I have noticed that about every third time or so I start up the VB6 IDE, a message box appears with the following error message:-
Method '~' of object '~' failed
This doesn't happen for any particular project or with any other thing in common that I have noticed. It doesn't appear to cause any problems after dismissing the message. My question is: ought I to worry about this, and if so, what should I do about it.
I have noted these other questions about the same error message here, here and here, but I get the message on opening up the project.
This is usually caused by locked clipboard on local machine. VB6 IDE add-ins use clipboard to copy/paste icons to toolbar buttons because the add-in API does not expose any other way of putting an image there.
Usually Remote Desktop client (mstsc.exe) is the culprit of the locked clipboard. The way Microsoft implemented transfer to remote clipboard is by probing local clipboard for available formats which locks it for a while. Clipboard is awfully designed global resource that can be accessed by a single process at a time and OpenClipboard API fails in flames for other processes if the resource is not currently available.
I used to occasionally run into this error and, in my case, it was caused by the Visual Source Safe add-in (bad install I guess; re-install corrected the issue). It never caused a problem; it was just a bother. As Jon stated in the comments, I would try shutting off add-ins to see if that fixes the issue. Another thing is to make sure you are running Service Pack 6.
I don't know about this specific error, but I do have some background information about this error message.
COM defines two levels of error information. All COM methods and properties have a return value with the type HRESULT, where 0 (S_OK) indicates success and negative values indicate an error. In addition there is a mechanism to provide so called "rich error information".
If a COM object generates rich error information, VB6 will show the information provided. If a COM object returns a negative value, but does not provide rich error information, then VB6 shows the message “Method '~' of object '~' failed”.
There are some standard error codes like E_POINTER and E_NOTIMPL which are often returned by COM objects in C++. All of these result in the message “Method '~' of object '~' failed”.
If you are implementing a COM object in C++, my advice is to always generate rich error information. (In ATL you just have to call the Error function.)
I uninstalled Visual Studio 6.0 and then re-installed it. This cleared the “Method '~' of object '~' failed” error for me. My VB 6 now appears to be functioning properly. I believe that, in my case, it has to do with several of the COM objects not being registered properly. My new machine received a ghost image from my old box which had VS on it.
I started getting this error all of a sudden on both of my development machines (one 32-bit, the other 64-bit). In my searching for a solution, someone made a tangential reference to SourceSafe.
Ahh, then it occurred to me that I had been recently cleaning up a project (clearing out .bak files, etc.), and one of the files I cleaned-out was 'MSSCCPRJ.SCC' (seeing how SourceSafe was - for our group - a distant relic, I felt "safe" removing this file from the project folder).
Long story short: restoring the file 'MSSCCPRJ.SCC' to the project folder, resolved this error.
I just came across this error while running VB6 on Windows Server 2012 R2. The offending Add-In was Visual Component Manager 6.0. Once I disabled that, the IDE was able to open without the Method '~' of object '~' failed issue. I'm not sure if that points to an installation issue or just "ancient" software on a "modern" OS.
For anyone else trying to install VB6 on Windows 7, 8, 10, 2012, etc., here are some useful links:

I just had the same experience when starting VB6 on my Windows 7 Ultimate desktop PC via a shortcut to a VB6 project (which, of course, starts VB6.) The notification box was titled "Visual Component Manager" and the message was "Method '~' of object '~' failed". It occurred when first starting the VB6 IDE, before the project was visible in the IDE. I have been using this process with this same project for several years with no issues, but today that message box popped up and had to be acknowledged. The one thing that I did differently today, and I believe this caused my problem, was to start an Excel 2007 workbook first and then start the VB6 project about three seconds later. Both were loading at the same time and they were probably battling each other for something they both needed. Starting my VB6 project by itself never results in this. Looking at all these responses, the one common thread seems to be that VB6 is unable to access some resources when they are needed. None of the responses suggest it is a serious problem; in fact, it appears to be simply a minor 'hiccup' until such time as the resources are freed.
I found the ultimate solution!
To avoid the "Method '~' of object '~'" message and avoid any "Windows Installer" message from running at startup of the VB6 IDE:
via the VB6.exe properties (after right-clicking on the file in Windows Explorer), ensure that VB6.exe has compatibility set to "Run in Windows 8" mode.
Ensure that the VB6.exe shortcut is set to NOT run as an Administrator.
With these settings it is OK to load any of the Add-Ins (including Visual Component Manager 6!)
It took me ages to work this out, but now VB6 loads with lightning speed and no annoying error messages.

After SSD failure, reinstalled Win10 and vb6. Application uses Far Point 2.5 spread sheet component, ss32x25.ocx. regsrv32 loads but call to DllRegisterServer fails w/code 0x80040201. Project Components display from IDE shows Far Point 2.5 in use, but project.vdp does not contain object reference "Object={B02F3647-766B-11CE-AF28-C3A2FBE76A13}#2.5#0; ss32x25.ocx".
When run in IDE, registry error above shows. Has also said "not registerable as an ActiveX Component".
Second machine, no failures, properly runs same app and displays objects being used. I have all support files for ss32x25.ocx.
Note that VB6 no longer installs cleanly due to Win10 changes; both machines have experienced that wild ride before ~ 3 years ago. This one looks just about ready to take off. Just need to fix registration.
I was wrong in my statement that object reference "Object={B02F3647-766B-11CE-AF28-C3A2FBE76A13}#2.5#0; ss32x25.ocx" was missing in the project.vbp file. It was 2 pages down the list.
This all started in re-loading visual studio. Somehow I learned loading only VB as admin were the keys to success. Reloading Far Point occurred somewhere in the process. But it wasn't a clean register for it or a home grown dll defining a batch of structures. regsvr32 loaded but failed some specific call.
Registration had to be the problem. I explored regedit and found Far Point looked good but my dll had gotten nowhere. Noting I still had to run the IDE as admin, I tried regsvr32 as admin for both items. Both were successful!
And, I don't have to run the IDE as admin!
Thank you for your reply and comments.
Let me describe the situation more detailedly.
I use Visual C++ 2008 to write a small application that will invoke MAPI. I use MAPIStubLibrary to support both 32bit and 64bit MAPI. MAPIStubLibrary can be found at https://msdn.microsoft.com/en-us/library/office/cc963763.aspx#sectionSection2 . It works on other versions of Outlook and most of the systems. However, under Windows 10(32bit) with Office 2016(32bit) installed, when I execute the following statement to initialize MAPI:
MAPIInitialize(NULL);
I will get the above error message "The operating system is not presently configured to run this application". And there will be an unhandled exception raised from the function GetDefaultMapiHandle(), which is in StubUtils.cpp, part of the MAPIStubLibrary.
The exact line that cause the exception is:
hinstMapi = LoadLibraryW(wzPath);
It seems that MAPIStubLibrary is trying to load 32bit MAPI but fails. wzPath is pointing to olmapi32.dll instead of msmapi32.dll.
In the error message, if I click “OK” button in the error messagebox, the application will continue running without problems. However, the error message is still frustrating and confusing the users. Therefore, how to eliminate the error?
Thank you very much.
This usually happens when you are either loading a wrong MAPI dll (e.g. olmapi32.dll instead of msmapi32.dll) or if your app is running in the compatibility mode (do you include a manifest?) and the MAPI system ends up patching wrong Windows API functions assuming an older version of Windows.
I have a VB6 application that I provide support for. This application works on both Windows XP and Windows 7. Some users were migrated from Windows XP to Windows 7 using the User State Migration tool. These users now receive a generic "Application has crashed" Windows error message when they open certain screens (forms) in the application. My assumption is that there is a missing dll/ocx reference, but I'm having trouble tracking it down.
I've tried many/varied troubleshooting techniques:
Full uninstall and reinstall of my application
Manually re-registering all dll's and ocx's that I know are used
Running Process Monitor on a broken computer and a working computer to compare what dll's and ocx's are accessed. The answer might be here but even after filtering out most of the background noise the amount of data is overwhelming. At a minimum I reviewed all of the calls right before it crashes and all of the calls that were not successful. All of the non-successful calls match between working and non-working.
Installed the Windows Debugger Tools and captured a crash dump. Analyzed the crash dump with DebugDiag. DebugDiag says the exception is in msvbvm60.dll. I tried building a PDB file for my exe and loading it in DebugDiag to get more detail about where the exception is occuring but DebugDiag doesn't want to accept the PDB (might be doing something wrong here, but it just seems to ignore it. This same PDB file works fine when I do remote debugging, however.)
I recompiled my VB6 program without any optimizations in PCode. I've read online that sometimes building in PCode, while bad for performance, will tell you the real exception.
Used the above created PDB file to remote debug the VB6 application. The debugger says that the application crashes after the new window has been created, on a line that sets MousePointer = vbHourGlass... To me it seems unlikely that this is the real cause of the error. There are at least 20 other locations in the program where this same line is called and all work fine.
(Forgot about this one)
Used Dependency Walker and profiled the application on both a working and non-working computer. All errors found by dependency walker were the same between the two computers. There were no additional dependencies found on a working computer, and all missing dependencies on the non-working computer were also missing on the working one.
None of these actions changed my error message or showed me what the error is (unless it really is the mouse cursor issue)... There are no entries in the Windows Event Log related to the app crash.
The non-working and working computers all have the same base Windows 7 image, the only difference is whatever is being changed by USMT, which further convinces me that this is some kind of quirky configuration change or a missing dll/ocx or perhaps an unregistered dll/ocx.
Any ideas or thoughts on how I can track down the root cause of the issue would be greatly appreciated.
Update 1 - Response to questions
#MarkHall I have tried running it as admin, though not with UAC off. The application runs fine on a Windows 7 box as a non-admin with full UAC. Windows XP was 32-bit, Windows 7 is 64-bit, but again it works just fine on a like for like box where the user was not migrated from Windows XP.
#Beaner It's possible that it stores settings somewhere that have been corrupted, but the remote debugging leads me to think that it's more likely something else since it seems to die on a step related to the UI, which then makes me think it's probably a missing dll/ocx reference.
#Bob77 The application is installed into Program Files (x86). While many of the libraries do reside in the same folder, they are all registered.
Peter, often I've noticed that the debugger will indicate a line of code that is actually incorrect, depending on WHERE in the actual assembly language the fault occurs. You should look REAL close around your statement that sets the cursor to vbHourGlass. Your exception is PROBABLY happening BEFORE that line of code, but that line is what the debugger thinks is the actual faulted line of code.
Since you said it happens when a window OPENS, I'd look real close at any ocx's you may have referenced on the form, but perhaps NOT actually being used, or called. You might have one there that you don't intend to be there, that could be causing security issues, or something on Win7? Edit the .frm file by hand if you have to, and look at all the GUIDs the form references.
It is possible that one machine is using PER-USER registration, and the other is using PER-SYSTEM registration?? I don't know...
I would take a much closer look at the form that you are trying to open, and be VERY cautious of everything you are doing in the form load events, and so on. This sounds like it could be something as stupid as Windows Aero being enabled on one system, and not another, or some other sort of "Theme" setting that is throwing the VB Form Rendering routine into a hissyfit... Perhaps even something as stupid as a transparent color index in the icon you selected for that from?
If you are still developing this app, (or at least maintaining it), create an entirely NEW form, and re-create all the controls, etc, on the form (resist the temptation to copy/paste them from the old one...), and then see if THAT does the trick. Then, copy all the event code to the new form one event at a time, with at LEAST enough event code to make the form function, even if it's just a "dead form", that loads no data, or whatever the form is supposed to do. Check and debug after each change, and you WILL find it eventually. Of course, make sure you isolate one of the defunct systems to have a platform that you can duplicate the issue on, or then it's just guessing. I find that using something like Acronis w/ Universal Restore is a great option to then take the image file into a good HV, like VirtualBox, and then restore that image as a VM, so you can debug without interfering with your actual users. This sounds like a lot of work, but then again, so is re-writing an application that already exists, right? :)
Failing THAT... /* and */ are your friends!! (Well, we're dealing with VB, so ' would be your best friend! heh... But I'd start commenting out all the code on the form until that sucker opens. Then once it opens, start putting one line back at a time, and re-running it... That's called "VooDoo Debugging", but sometimes, you gotta do what you gotta do...
THANKS A LOT PETER! :) Now you got ME so involved in this, I feel like I'M the one debugging this sucker! Like if it was MY code I was trying to fix! :)
Let me know if any of this helps... I am actually quite interested in what you discover.
I have a completely random error popping up on a particular piece of software out in the field. The application is a game written in VB6 and is running on Windows 7 64-bit. Every once in a while, the app crashes, with a generic "program.exe has stopped responding" message box. This game can run fine for days on end until this message appears, or within a matter of hours. No exception is being thrown.
We run this app in Windows 2000 compatibility mode (this was its original OS), with visual themes disabled, and as an administrator. The app itself is purposely simple in terms of using external components and API calls.

Resizer XT
As you can see, these are pretty straightforward, Microsoft-standard tools, for the most part. The database components exist to interact with an Access database used for bookkeeping, and the Resizer XT was inserted to move this game more easily from its original 800x600 resolution to 1920x1080.
There is no networking enabled on the kiosks; no network drivers, and hence no connections to remote databases. Everything is encapsulated in a single box.
In the Windows Application event log, when this happens, there is an Event ID 1000 faulting a seemingly random module -- so far, either ntdll.dll or lpk.dll. In terms of API calls, I don't see any from ntdll.dll. We are using kernel32, user32, and winmm, for various file system and sound functions. I can't reproduce as it is completely random, so I don't even know where to start troubleshooting. Any ideas?
EDIT: A little more info. I've tried several different versions of Dependency Walker, at the suggestion of some other developers, and the latest version shows that I am missing IESHIMS.dll and GRPSVC.dll (these two seems to be well-known bugs in Depends.exe), and that I have missing symbols in COMCTRL32.dll and IEFRAME.dll. Any clues there?
The message from the application event log isn't that useful - what you need is a post mortem process dump from your process - so you can see where in your code things started going wrong.
Every time I've seen one of these problems it generally comes down to a bad API parameter rather than something more exotic, this may be caused by bad data coming in, but usually it's a good ol fashioned bug that causes the problem.
As you've probably figured already this isn't going to be easy to debug; ideally you'd have a repeatable failure case to debug, instead of relying on capturing dump files from a remote machine, but until you can make it repeatable remote dumps are the only way forwards.
Dr Watson used to do this, but is no longer shipped, so the alternatives are:
How to use the Userdump.exe tool to create a dump file
Sysinternals ProcDump
Collecting User-Mode dumps
What you need to get is a minidump, these contain the important parts of the process space, excluding standard modules (e.g. Kernel32.dll) - and replacing the dump with a version number.
There are instructions for Automatically Capturing a Dump When a Process Crashes - which uses cdb.exe shipped with the debugging tools, however the crucial item is the registry key \\HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AeDebug
You can change your code to add better error handling - especially useful if you can narrow down the cause to a few procedures and use the techniques described in Using symbolic debug information to locate a program crash. to directly process the map files.
Once you've got a minidump and the symbol files WinDbg is the tool of choice for digging into these dumps - however it can be a bit of a voyage to discover what the cause is.
The only other thing I'd consider, and this depends on your application structure, is to attempt to capture all input events for replay.
Another option is to find a copy of VMWare 7.1 which has replay debugging and use that as the first step in capturing a reproducible set of steps.
Right click your executable object and let it be WINXP compatible pending
when you discover source of the problem to finally solve it
We've been plagued for several years by occasional reports from customers about a non-descript error message "Cannot set allocations" that appears on startup of our app. We have never been able to reproduce the problem in our own test environments so far. I have now run out of ideas for attempting to track this down. Here's a collection of observations that have accumulated over time:
Error message text reads "Cannot set allocations" (note absence of punctuation).
The window title simply reads "Error" (or the localized equivalent).
The "Cannot set allocations" text is always in English regardless of OS locale.
I have so far not been able to locate the DLL or EXE containing the message text.
Google is chock full of reports of this error for a variety of different products - but no solutions.
The only unifying aspect between the affected products I could make out so far was that they all appear to come in the form of DLLs that load into third-party processes (such as addins for Visual Studio or Windows Explorer shell extensions).
Our app is actually a shareware COM-addin for MS Outlook, written in Delphi (i.e. native code - no .NET).
The prime suspect in our case is the third-party licensing wrapper that we're using which decrypts and uncompresses our DLL into memory on the fly. Obviously I couldn't simply give an unprotected version of our app to the affected customers to verify this suspicion. Maybe the other vendors that this has been reported against are using similar products.
Debug versions of the protection wrapper supplied to us by the licensing vendor yielded no results: The log files looked exactly the same as from sessions where the error did not occur. Apparently the "inner" DLL gets decrypted and uncompressed all right but for some reason still fails to get loaded by the host process.
By creating an unprotected "loader" DLL we have been able to pinpoint the occurrence of the error somewhere behind the LoadLibrary call that is supposed to load our DLL into memory.
Extensive logging and global exception hooks in our own code (both the unprotected loader and the protected "core"-DLL) yielded no results at all. The error is obviously raised somewhere else.
The problem described in this earlier question of mine was very probably prompted by the same issue. This was before we created the unprotected loader stub.
The error only occurs at about 1-2% of our customers - whereas typically all installations at any affected customer's site are affected the same.
Sometimes the error goes away after we release a new version but often it will come back again after a couple of weeks or months.
Once the error has started to occur on a machine it does so consistently.
The error never occurs while connected to the affected machine via remote access (e.g. VNC, RDP, TeamViewer, etc.) and none of the affected customers are within travel distance from us so all we have to go by is log files and "eye-witness reports".
One customer reported that the error message dialog apparently was non-modal, i.e. he was able to simply move the dialog box to the side and continue working with the application (minus the functionality that our DLL would have provided). Not sure whether this is universally true in all other occurrences, too.
In some cases customers have been able to permanently rid themselves of the error by disabling or uninstalling other addins from other vendors that were sharing the host application with our own product.
The error has so far been observed on Windows XP, Vista and 7.
During the last few weeks we had a surge of reports from Outlook 2003 / Windows 7 users. Could the situation have been made worse by a recent Windows/Office-update?
Does anyone have any experience with this error at all?
Or any more ideas for investigating this?
I have only recently had this happen, which prompted my search and I ended up here. I can tell you that with me for sure it is in windows 7 home premium BUT ONLY WITH IE9 (which I hate by the way) it reduces the user back to the dummy stage and assumes that we have to be repeated flagged about everything.It will keep asking you if you want to disable add ons to speed up load times but usually on things that aren't really the things slowing the browser down in the first place,it is there is too much garbage loading in the first place.But back to the "Cannot set allocations", I for one have never expirianced it in any other browser which is not to say it doesn't happen with them.
This is going to be pure guess-work, but it sounds like maybe your third-party licensing software is trying to load your DLL at a particular location in memory, which - on these failing systems - happens to already be occupied by something else, perhaps a global hook DLL.
If you have a customer who is willing to work with you a bit, it might shed some light on the situation to get a crash dump (e.g., with ADPlus or maybe simpler with Sysinternals' ProcDump) when the error message is showing. That would show what modules are loaded and possibly the callstack (if it is from a message box at the time of the error as opposed to one that is catching an exception after the problem).
I also have experienced the "Cannot set allocations" issue. Royal pain. I had disabled Java, since I did not seem to need it, I used add/remove programs to remove Java from my system. Then I stated to get those errors. I have reinstalled, but disabled Java in IE explorer. Now I do not get the error anymore. Not a programmer, don't know why this happened. Maybe a clue for someone.
Win 7 - 64bit OS IE Explorer 10. Hope this helps someone figure this out. John
I've seen this happen. In my case a global hook dll created a large memory file mapping, perhaps to the memory the licensing dll was counting on.
I see "Cannot set Allocations" when I open google chrome only. Also after that, chrome closes with a msg saying "Whoa chrome has crashed..."
Still no solution :(
Also not a programmer, but it always happens when I open Chrome. It opens second window with error message 'cannot set allocation'. I usually close it and go on my way. if i don't it usually causes a crash. doesnt happen on any other browsers.
