Compiling the software problem - vb6

Using VB6
i created a software in vb6 with xp operating system, In my system, software is working perfectly. When i run my software in other system(xp operating system), it showing error as cannot find project or library, showing error in Date, Left...,
Now i moved to vista operating system, i try to run my software, It showing the same error.
How to solve this issue.
My software is running in my system, when i try to run my software other system it showing error and also i try to run my software in vista also it showing a same error.
What happen in my code. There is any system32 file problem?
How to solve this issue.

Sounds like you need to create an installation for your VB6 project, to install the VB6 runtime and any non-standard components used. The runtime should be present by default on Vista, so it's probably non-standard components that are missing.
Consult the answers to your own previous question in August, when you asked how to make an installation for a VB6 program. (Even that August question was already a duplicate.)

You need to also copy the controls, and referenced files to the machine running your code. Some controls and referenced files will already be on the machine, but without experience you generally will not know which files are already installed. You can look at the checked files in the Project|References and Projects|Components dialogs to see what is included in your project. You will need to scroll through the components dialog to find all referenced files, but in the references dialog all the references are organized at the top. Also, to confirm what file(s) a machine is missing you can look at the Events log. An error with the missing file will be logged. A drawback of this approach is that you will only get one missing file at a time as the Application quits on the first missing reference encountered.
Also MarkJ and Konamiman are both correct in that the VB6 runtimes are required, although it is common for other VB6 programs to have already installed it. If you are not building in-house applications you do not want to take anything granted and should build a complete install for your application.

The other computers must have the VB6 runtime in order to run applications generated with VB6. Maybe is this the problem?
The VB6 runtime can be donwloaded from here: http://www.microsoft.com/downloads/details.aspx?FamilyID=bf9a24f9-b5c5-48f4-8edd-cdf2d29a79d5&displaylang=en

Use the Package and Deployment Wizard to create a setup.exe. The Wizard will automatically include all the files you might need for distribution.

How do I create an installer exe with system ocx and dlls for a VB6 exe?

This question may seem really dumb, my apologies for having very minimal programming experience. We just need to make an inventory system exe given to us run and "work" on some computers.
The exe file itself is an inventory system made using Visual Basic 6. It runs fine on computers that have visual basic 6 installed.
However, on computers without VB6, we encounter crashes. The exe's themselves run fine but as soon as we perform something (logging in/clicking buttons/etc.), we get runtime errors 339. On one machine it says, "Component 'MSCOMCT2.OCX' or one of its dependencies not correctly registered: a file is missing or invalid. on another machine, we have a similar error but points to MSFLXGRD.OCX
I figured these problems may be caused by missing system files/dependencies and we need to first install those. How do I make an installer wizard (similar to those Windows app installers that installs system files alongside the actual app) for installing these missing dependencies?
You could do a lot worse than the free Inno Setup. I've used it for many VB6 projects and it's never failed me. There's a learning curve but it's a very flexible package.
I used to use (and contributed to) the WiX toolkit for this purpose.
This will build a standard .msi installer for you. Start with the heat program which will inspect your software and generate much of the WiX project for you, be sure to use the -svb6 option.
You will need to source the appropriate merge modules for VB6 as well, which will provide the components you are missing.

Installing Oracle form and got an error. Cannot launch the installer (555)

Oracle form downloaded at:
http://www.oracle.com/technetwork/developer-tools/forms/downloads/index.html
When I ran the file setup_fmw_12.2.1.3.0_fr_win64.exe,
it gave me an error "Cannot launch the installer (555)".
fmw_12.2.1.3.0_fr_win64_Disk1_2of2 <-- Folder
setup_fmw_12.2.1.3.0_fr_win64-2.zip
fmw_12.2.1.3.0_fr_win64_Disk1_1of2 <-- Folder
setup_fmw_12.2.1.3.0_fr_win64.exe
Even though this relates to the installation of a developer tool, most would consider this particular type of question as generally off topic for stackoverflow. Your question also contains too little information to determine what the problem really is.
However, let's just mention some obvious things to see if it helps you solve your own problem:
Did you try the setup on another computer (or a virtual machine). This could be a good way to avoid the whole problem rather than spending a lot of time trying to fix it.
Did you locate any log files for the failed install?
A quick look seems to indicate that you can find log files at: %SystemDrive%\Program Files\Oracle\Inventory\logs (%SystemDrive% is normally C:\).
Or %SystemDrive%\Program Files (x86)\Oracle\Inventory\logs for 32bit installers on 64 bit systems).
Found in the troubleshoot section here - have a look yourself too - read from the top.
And the most obvious of all: did you contact Oracle support or search their user community or knowledge bases? Somebody will have seen this problem before. Looks like you need to register: https://support.oracle.com/
A quick search reveals that the Oracle Universal Installer is a Java based installer. Could Java be broken on the box you install on? (looks like the launcher should install the runtime automatically, but this could fail due to special conditions on the box. Try on a clean virtual machine). How to check whether java is installed on the computer.
Try disabling your anti-virus as well before running the setup on the problem box. Some setups even try to access the Internet during installation, and then your firewall could be a problem too. I would hate to turn that off though.

VB6 application causes install to show up

I got a weird problem with my VB app that has got me very confused. I am updating an existing program. I had to add some processing queue capabilities. On my system, unit testing worked great but when I compile it and run it on a different computer (a network server machine) it first tries to open an office install. If I cancel this, the program seems to run fine. The problem is that this program will be run in the background and I can't be hitting cancel each time it runs.
So my question is this: what is going on here? I'm usually a java developer we eclipse so I'm used to being able to include all the needed libs into the jar files automatically. It doesn't seem like the case with VB6. it seems like it expects all the same libs to be on all the systems. Is there any way to tell what might be triggering this?
The only thing I can think of that is causing it is that I'm using the "OpenProcess" function in the kernal32 lib. that the only major change I have made.
any help would be very appricated. thanks!
EDIT:
It seems that multiple versions of word were installed on the system and it was screwing things up somehow. We uninstalled one and it fixed it.
I ran into this a while ago and it was related to my installer for the VB6 app overwriting some system files for Office that it shouldn't have. Any time one of the System dlls was accessed Windows would determine that something was wrong and the Office installer would start up.
The short-term fix was to let the Office Installer repair the broken chain of dlls.
The long-term fix was to never overwrite built-in Windows System dlls.

Unable to load VB6 OCX in Windows 7 Error 372

I'm working on an application developed for Windows XP SP3, using VB6. I'm currently in the process of getting it to work on Windows 7, but am encountering a problem with one of our custom OCX files.
When attempting to load a form that contains an instance of the control contained in the problem OCX, the following error is produced:
Failed to load control 'x' from y.ocx. Your version of y.ocx may be outdated. Make sure you are using the version of the control that was provided with your application.
I've checked the version numbers and they're all correct and referencing the proper version. The OCX registers fine, and all the expected registry entries are present.
Inspection with DependencyWalker shows no missing dependencies.
The software works fine under XP, and this is (seemingly) the only issue when running on Windows 7.
Interestingly, if I run through the VB6 IDE using a VB6 group (with the offending OCX part of the group, and the application the startup project), I don't have the issue. Running the application on it's own through the IDE still presents the error.
Any ideas on what could be missing which would cause the application to throw this error?
Error occurs on both Windows 7 Professional and Home Professional, both 32 bit.
This is almost certainly an interface compatibility problem. COM interfaces are versioned entirely separately from your Major/Minor/Revision numbers, which are little more than comments except as used by Installer.
Somewhere along the line you broke binary compatibility, and you are trying to deploy a library with a newer interface than your application was compiled against.
These version numbers are found in keys such as:
HKEY_CLASSES_ROOT\CLSID\{class Id GUID}\VERSION
Your program needs to have its old reference to the OCX removed, a new one set, and then it must be recompiled. This also means deleting any instances of the control and adding them back one by one.
I doubt this is a Windows 7 issue.
I would suspect this is a UAC problem. Try turning UAC off to see if that solves the immediate issue. If it does then you have to regsiter everything using 'run as administrator' and/or create a manifest for you application.
Sounds like on of the controls included in your OCX is having issues loading, not a general registration error. Look at the constructors for x control, and see if they are doing anything that disagrees with UAC or such. One way you can debug this is put some kind of a break before the control is initialized, and debug the application from Visual Studio (remember to create the PDB's in VB6), and then carry on from the break to see why the control isn't initializing.

What causes the Vista/Win7 warning: "This program may not have installed correctly" ?

What causes this warning and what can I do to keep it from popping up when my app installs?
Possible causes:
Virus scanning software (I'm looking into that)
Not putting the uninstall in the Add/Remove programs (this will definitely cause the problem, per documentation from Microsoft (see answer below)
Putting .ocx or .dll files in the App Directory?
Not registering the library files (app runs fine without reinstalling, so I don't think this is it.
Any other ideas?
To fix this, see this blog post by Aaron Stebner:
Your app is probably being detected by the PCA (Program Compatibility Assistant) as a non-Vista (pre-Vista) installation application.
You will need to add an embedded manifest and set a requested execution level
There is a previous stack question on this topic as well with some alternative work-arounds (noob, I can only post one link at the moment). You should be able to find some information on Vista-aware installation applications and be able to resolve this issue, but the info above has worked for me in the past.
One of the reasons this pops up is that after running the installer, the system checks to see if something changed in the installed programs list. If the contents of the installed programs list hasn't changed, it assumes that your application failed to install correctly.
I think this is related to operations which may be denied via UAC. (Not sure what exactly - file copies to restricted areas?)
To keep this from occurring, run the installer as an administrator.
