Deploy QT WebKitWidgets app to windows XP - windows

Coming from Linux, using QT5.4 (app compiles and works as expected)
If you are interested in the topic, just get fancybrowser example running on a XP machine without QT installed...
My first attempt was using MXE (and manually copying dlls). No success.
set up VM with Windows XP.
using windeployqt.
app "works" but QWebView doesn't display anything.
trying qt.conf
[Paths]
Prefix=.
and more things.
Still not successful.
windeployqt with all options to include webkit, compiler, angle...
No success...
Reading about QWebEngine will be the next.
Compiling a small example on Linux(OK) Windows (Mingw does not support qwebengine!!!).
So before setting up a new vm with windows 8 (msvc 2010 does not support qwebengine) and may find out the the app won't run on XP....
and porting from QWebView to QWebEngineView....
Please help:
How to deploy webkitwidgets app on windows? (without installing Qt, which will be my last chance...)
Edit
Next step done was Running ProcessExplorer on the dev machine and on the target machine. Parsing the output of the loaded dlls on both machines, they do not differ. All required dlls are loaded? Still no display...

The problem should be solved in Qt5.5.1 which was released last week.
Just use the Deploy Tool of Qt :)

Running GTK# applications on Windows 10

I have built a C# and GTK# program with Mono on Linux, and now I'm trying to run it on Windows 10. To see if I can get anything to run at all, I'm trying the HelloGTK example from the MonoDevelop documentation: http://www.monodevelop.com/documentation/stetic-gui-designer/
On the Windows 10 machine, I first tried installing Mono (32-bit), and running the application from the Mono command prompt as mono HelloGTK.exe, but it terminates instantly without any error message. I then tried uninstalling Mono and installing Gtk#, but with the same result: the application terminates silently when run from the Windows command prompt.
Could it be a .NET version mismatch, or missing .NET components? .NET is enabled (versions 3.5 and 4.6) in the Control Panel, but not all sub-items are checked. The program is built against .NET version 4.5.
I built a console application (with Mono on Linux) and it runs on the Windows machine without Mono installed. Is this enough for verifying the .NET status or could it still be an issue?
Could it be that the application does not find the GTK# libraries? Is there any way to verify the GTK# installation?
Could it be a GTK# version mismatch? The application is built against GTK# 2.12, and I installed 2.12.38 on the Windows machine, so I find this unlikely.
Any hints on how to troubleshoot this issue would be most appreciated!
forget all that:
native docker is now available on windows, so:
dockerize your app and make your image
copy to a windows box
run in docker
done
plus some details that probably need to be filled in. but docker works and will make your life infinitely easier where cross-platform issues are concerned.
The problem turned out to be in the code generated by the Stetic GUI designer which is included in MonoDevelop:
protected virtual void Build ()
{
...
this.Title = global::Mono.Unix.Catalog.GetString ("MainWindow");
With the above line commented out the application runs on Windows 10 with GTK# installed.

Native x64 dll does not work

I have an application that I compile as x86 code but as a separate version, as x64 code as well. The application basically has two parts, a c# managed exe and a c++ unmanaged dll. I have problems with the latter. On my development PC (Windows 7 64-bit, Visual Studio 2008) I create a setup with a deployment project and this setup installs the application in Program Files... as it should and the application runs. I also have a test PC (Windows 7 64-bit with practically nothing else). There the application still installs into Program Files... but it does not run, I get the BadImageFormatException when a function (any function) of the unmanaged dll is called. The problem is that my own project that produces the dll also makes use of quite a few freely available libraries (e.g. glew32, openal, freeimage, etc.) I took as much care is possible to make sure that I use the x64 versions of these libraries, but something still must be wrong. For some reason one of the libraries used by my dll is not available as x64 code on the test PC but it is on the development PC. At least that is the only explanation I have at the moment why my setup works on the development PC but not on the test PC.
My question is: how can I find out where the problem is. The error message I receive does not tell any helpful detail. I tried to analyze my dll with depends but it looks OK. It lists a lot of dependent libraries as X86 (these are probably system files) but all those that I use on purpose are listed as x64.
Is there any way to test why the Windows on my test PC tries to run the DLL as x86 code even though it should be x64?
Thanks.
I noticed something very strange: My application is being deployed in the Program Files folder as it should be for a x64 application but it fails to run. However if I copy all the files in the folder it is installed to to another folder (inside the Documents folder) the application runs perfectly.
Run Fusion Log Viewer in the machine where you want to diagnose the issue. Look carefully at the logs and you'll see exactly which dlls are being loaded, and where from.
You have build your .NET executable (or DLL) with Any CPU configuration, and you have given x64/Win32 native DLL for Win32/x64 (i.e. wrong config).
On x64 systems, your .NET binary will try to load the native DLL as if native DLL is x64.
And on 32-bit systems, it will try to load 32-bit native DLL.
I found the answer. The problem was not the 64-bit dll at all. One of the libraries I did not make but I link to (I do not know which yet, there) seems to try to write a file to the application folder. Of course, this is not allowed inside the Program Files folder unless you run the application as an administrator. Sorry for asking help for the wrong question.

vb 6.0 program on windows 7

I have been trying to install and run a program written in vb 6.0 on windows 7. It was working fine installing and running in windows xp. The error message after installing and running it say that
Run-time error 339" : Component voice.ocx or one of its dependencies not correctly registered: a file is missing or invalid.
This program has voice recording things.
I manually register that ocx component but still error that shown like
The module "voice.ocx" failed to load.
And I try to install VB run-time and still shows the same error. I believe that Windows 7 support vb 6.0 programs.
One thing here I am not sure of is that the ocx component I have is whether 16 or 32 bit version. I don't think we cannot register 16 bit version ocx in windows 7.
And I also try to install and run in compatibility mode or even as administrator. I think it is a platform related issue? And it might be some other work-around. So, I appreciate your hints or clues on this program runnable in windows 7.
Thanks in advance.
Regards,

Just encase anyone else sees this.. here is what I did
I knew the program was running on Windows XP, with visual basic installed. I had only been given the exe and the MDB. So I created a virtual machine (stick with me) of Windows XP, installed visual basic and test the app. It was fine. Then I downloaded a dependency tool called Dependency Walker from http://www.dependencywalker.com/. I installed this in the virtual machine and asked it to open my exe.
Once this was loaded I ignored the warnings and asked it to start profiling. I ran the app, stepped through everything I could see, then exited the application. This left me with a log of the DLLs that had been accessed. Slowly I went through these checking if they existed on my windows 7 setup, when one was missing I copied it to my application directory and then from an elevated command prompt run "regsrv32 [missing_name.dll]" until there were no files which my windows 7 desktop didn't have.
the application then worked fine! This may not work all the time, because of the way third party OCX's or DLLs have been written. But it may help someone out.
Few of old Win32 components are not supported in Windows 7. There are possibilities of failure of a VB Program in Windows 7.
But there are some possible ways to fix those.

I have developed several programs with VB5 on a WinXP32 machines and then installed them on Windows 7 (32 and 64) PCs without problems.
This applications use different OCXs (16 and 32 bit version) and till now I never get problem with them. Thus I do not think that the VB5 or Vb6 could have any issue on Windows 7 machines.
On the other hand I would point out the module "voice.ocx" and investigate if it can run on a windows 7 pc, because as Katturaja sais some old ocx have problem on win7. To do that, I would create a simply VB6 project that uses voice.ocx (just an Hallo-World"), then create the installation pack and finally try to install on a clean win7 machine (for example a virtual machine). In this way you could isolate the problem.
I hope this could help you.

Has anyone had success with Visual Studio 6 on Windows 7?

VS6 popped off a series of errors before bombing out completely during install on Windows 7. I specifically need to get VB6 functioning on Windows 7. Anyone having any luck?
Folks on the VB6 newsgroup report they have managed to get it working on Windows 7.
There's this step-by-step guide on how to install the IDE on Windows 7 (including 64 bit).
If that doesn't work (scrapes barrel) try this old tip about persuading the install not to install the Java VM? Link is now broken so here is the tip:
Before trying to install VB6. Create a new file, name it msjava.dll and place it in your windows directory. The file can be zero length. You can then happily install without the prompt to install an old version of Microsoft's flavour of Java. Once you have installed VB6, delete the msjava.dll otherwise windows update will prompt you to update it.
Or (scrapes hole in barrel) these tips from an article about getting the IDE working on Vista?
Footnote: if developing with ADO, be aware of this.
The only way I've found that works is Windows XP mode (i.e. a virtual machine). Works fine there, but otherwise, not at all.
I found ALL the answers in a thread at vbmonster.com. As mentioned above, you CAN install Visual Studio 6 with Service Pack 6 under Windows 7 by following Derek's detailed instructions at fortypoundhead.com.
I had a problem because I needed to install Service Pack 5. I use a third party program that does not work with Service Pack 6. A really smart programmer (GuideX) came up with a great hack to get around the MDAC 2.5 error.
Win 7 64 bit service pack 5 & 6. Turn compatability off and it seems to work.
Recently I had to debug an ancient application written in Visual C++ 6.0 on Windows 8.1. Tried different solutions all of them failed, only this one worked.
This guys made a special installer that allows installing VC++6, VB6, and SP6 on Windows Vista/7/8/8.1/10 without any errors whatsoever.
Hope it would be helpful to someone.
I installed VB6 on Windows 7 Pro without having to use compatibility settings or run as administrator.
Doesn't really help you, but does show that it can work.
Several people in my office have installed Visual Studio 6 (without VC++) on Windows 7, both 32-bit and 64-bit with no problems. The one thing we have in common: we've all turned UAC down to it's lowest setting. Nothing else special required.
I am using vb6 on windows 7 32 bit system for a long time.
you will need to install your vb6 with compatibility of xp2.
Create a 0-byte file in the C:\Windows directory called msjava.dll.
Don't just install via the Autorun executable; instead browse the Visual Studio 6 CD (or folder), right-click Setup.exe and select Run As Administrator.
On any Program Compatibility Assistant warnings, click Run Program.
Step through the setup screens until you're able to choose Custom Setup, then click next.
On the setup options, install the following items and nothing else:
Microsoft Visual Basic 6.0
ActiveX
Data Access
Graphics
Click continue and the process will start, and (hopefully) eventually complete.
Skip the installations of the MSDN CD, BackOffice, VSS and SNA Server, and clear the checkbox for "Register Now". Setup should be complete.
Download the VB6 Service Pack 6 from http://www.microsoft.com/downloads/en/confirmation.aspx?FamilyID=A8494EDB-2E89-4676-A16A-5C5477CB9713&displaylang=en and install.
Change the compatibility settings for Visual Basic (to get it to run a little more smoothly under Windows 7) by browsing to C:\Program Files\Microsoft Visual Studio\VB98, right-clicking the VB6.exe file, and selecting properties.
On the Compatibility tab, check the following:
Run this program in compatibility mode for Windows XP (Service Pack 3)
Disable Visual Themes
Disable Desktop Composition
Disable display scaling on high DPI settings
When you start up the IDE, you may get a notification saying that the color scheme has been changed to Windows 7 Basic, but it will be changed back to Aero once you exit. Everything should be working fine at this point!
Note: when you first run your new install vb6 run it with admin rights and with xp2 compatibility so that your exe can run on any system.
The word "supported" is used loosely in this thread, potentially leading the unwary reader to the conclusion that Microsoft supports the VB6 IDE (that is, the integrated development environment) on operating systems beyond Windows XP. This fact clearly is stated in the table that appears on the page at this link:
https://blogs.msdn.microsoft.com/nikosan/2012/04/20/support-statement-for-visual-basic-6-0-on-windows-8-updated/
Note that executables developed using VB6 are in fact compatible with Windows OS's from Windows XP through Windows 10--32/64-bit versions:
https://blogs.windows.com/buildingapps/2015/06/22/getting-ready-for-windows-10-sdks-compatibility-bridges/
Anyone using non-standard methods to coax the IDE into working on OS's that Microsoft does not support is exposing themselves/their organizations/their employers to risk and is not suitable for risk-averse organizations.
Having said that, I think the purest solution is to install Windows XP onto a virtual machine and run that VM in a modern host OS, such as Windows 10. That works just fine, and you can install directly from the VB6 Setup disc without making any pre-install/post-install customizations.
I had a Vista x64 box with a working copy of the VB6 IDE (which was supported). I upgraded the OS to Windows 7 x64 and the VB6 IDE still works fine. You could try that. I know, a huge PITA and kludgy but still, it worked for me.
I run Windows 7 Ultimate 32-bit, installed Windows Virtual PC - XP Mode, and that solved my problem isince I can run MSDEV 6.0 in the XP Window.
Not esay to install XP Mode though, the MS site is buggy.
The VB6 programming language is supported on the Windows 10 Technical Preview.
Visual Vasic 6 applications run and the VB6 IDE installs and works too.
I have the VB6 IDE running OK on Win-XP-16, Win-7-32, Win-7-64, Win-8.1-32, Win-8.1-64, win-10-32 and win-10-64 by using the instructions above which basically say, turn off UAC, run the installer AS ADMIN, and then set the VB6.exe file to run in XP-SP3 Compatibility mode.
I have had some issues with it and have had to do a bit more googling to solve these but I don't remember any more what those issues or solutions were.
I've even got the VB3 IDE running on the 32-bit versions of XP, Win-7, Win 8.1 and Win-10 - without even installing them - just copied the C:\VB folder from another computer and copied the *.LIC license files and *.VBX etc files as well.
I have successfully installed vb6 on win 7 32 bit by installing xp first then installing new win 7, (not upgrade), and do not format. then it will install vb6 without a problem
It's depending on your build version of Windows 7.
If your Win7's version is lower or is not updated, it has MANY PROBLEMS with compatibility.
But mine is newer Win7 version and has NO COMPATIBILITY TROUBLE.
I am currently using VB6 , VS6 and they still work fine!
If Properties->Compatibility->Windows XP doesn't help, fix it with UPDATING your Win7.

GHC + wxHaskell on Windows

Have GHC 6.8.3 and wxHaskell-0.10.3 on a Windows XP computer. Installed both as binary distributions, not by building from sources. Built a sample with the following command:
ghc --make Paint.hs
It works on that same computer it was built on (with GHC and wxHaskell installed), but fails if transferred to another one (with neither of them installed). It throws an "Application error" box with "The application failed to initialize properly (0xc0150002). Click OK to terminate the program."
The only non-system dll it wanted was wxc-msw2.6.4-0.10.3.dll, which I copied to it's folder.
What might be the reason?
The error comes from dependencies that are mentioned in the manifests of DLL's (presumably the third-party ones with wxHaskell) that your system is expecting to find installed in places such as WinSxS and SoftwareDistribution in your Windows directory. I am guessing the wxHaskell installation puts the files there.
You may be able to find what files the program is looking for by looking in the event viewer on the failed machine. You may even be able to fix them by moving the files from a working machine, However, VC++ 2005 runtimes are the most likely, as suggested - the wxHaskell troubleshooter suggests you try the VC++ 2005 service pack 1 redistributables:
http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647&DisplayLang=en
My guess is, you want to install the VC++ runtime redistributable files onto the target computer. The redistributable files for applications built with visual studio 2005 are available from here:
http://www.microsoft.com/downloads/details.aspx?familyid=32bc1bee-a3f9-4c13-9c99-220b62a191ee&displaylang=en
Datapoint: Works for me on an XP sp2 box.
