just like it.
I had tried change the system, such as win10, linux. I also tried replacing the xe file but that didn't work either。

I am making app to increase productivity in our company. It reads the whole .csv file and puts its contents to a table in .pdf format. I am using QT as GUI library and PoDoFo as .pdf library.
The thing is, after I let user select .csv file to get data from and path to save generated .pdf, the program crashes in two minutes or so. It varies from case to case. I was able to "track" the issue down to the QFileDialog.
It doesn't matter if I created it on the stack, or dynamically still the same thing happens. From the moment you press "Choose" in the GUI, which opens up file dialog, program will crash in something around a two minutes giving this in Visual Studio Community 2017
I was able to create minimalistic code, to reproduce the error. I am using Windows 7 Pro, Microsoft Visual Studio Community 2017, compiling 32-bit debug
.h,.cpp,.ui files: https://www.dropbox.com/sh/cf057p4lnumesol/AAD39zDJnrxGChXAuE7y27Kra?dl=0
Any help would be appreciated, I've spent 5 days of my free time trying to figure this out. Thanks
EDIT: I understand that the "Frame not in module" means that visual studio doesn't have debugging symbols for the part of code where crash occurred, since I did not built qt myself, that makes sense.
EDIT2: I am using QT Visual Studio Tools addon version 2.3.2
Qt version is 5.12.2
EDIT3: Crashes only occurs when compiling for 32-bit arch.
EDIT4: Crash is happening only if using native file dialog. If option QFileDialog::DontUseNativeDialog is set, then no crash occurrs.
Not sure if this is related, but I had an issue where if I gave a path to the FileDialog it would grind away for a few seconds because it was somehow interpreting it as a network path. To fix this I gave it a path that had a prefix of "file://". To accomplish this I did this:
QUrl().fromLocalFile(cell_info->progDir()).toString()
The original path came from cell_info->progDir(). Somehow that path was a regular windows specific path. Once I wrapped it in the from LocalFile call it produced what I needed for all platforms I was using it with.
Again, I have no idea if this is related to your issue, but it sounds fishy like it is grinding away in the background on something. If this is not related feel free to ignore.
I used the online download of Qt to install it on my desktop but now I also want it on my laptop and I am unsure of how I can do that without having to re-download. My internet connection is crap and I don't even know if the Laptop will allow me to considering that it is one issued by my school and not all downloads work. Please help! I tried copying all the files over to the laptop but now all the settings are weird because the computer I am using doesnt have (or allow access) to the C drive.
I've looked at where does an installed version of Qt store the paths.
It seems that you need to change the following:
Qt5.2.1/5.2.1/[compiler]/mkspecs/modules/qt_lib_[module].pri
In each of those files, change the line that begins with QT.[module].rpath.
I have my code working perfectly on Visual Studio C++ with OpenGL. The code is able to call the images folder. And when I run the program the images show up on my application.
Now I am trying to run my OpenGL C++ program on my Mac. Everything compiles and runs. However, the images that I use are not showing up.
Here is a screenshot of how my project directory looks. I have the images inside the texture folder.
Is there specific place where I need to put my texture folder so they will be able to be loaded? Like I said it works fine on the windows visual C++.
Given the screenshot you posed in the comments, it could be because you're using backslashes for the path separators. UNIX-based systems (Mac, Linux, BSD, etc.) use forward slashes to separate directories - Windows is fairly unique in using the backslash. Conveniently, Windows functions will accept paths with forward slashes anyways.
Currently we are migrating our applications developed in Borland C++ 5.02 on Windows XP to Windows 7. While executing the application on Windows 7, I am getting the error message
VBX library init Failure.
While trying to find the cause on the Internet, I was able to identify the error was because of BIVBX31N.EXE and BIVBX31N.dll.
How can I port a Borland C++ 5.02 application to Windows 7, solving the BIVBX31N.EXE and BIVBX31N.dll related issues?
If you're stuck using this product, here is what I recommend.
Simple answer: Don't use the IDE, but continue to use the command line tools:
bcc32.exe (the compiler) still works fine in Windows 8.
ilink32.exe (the linker) still works fine as well.
Both can be found in the bin sub-folder.
You can get some of the command line information by opening the IDE (project) file in Notepad or a hex editor (it isn't a text file, but you can read most stuff in Notepad). Or if you do have access to Windows XP you can open it there just to copy the settings for usage in the command-line tools.
Just use some other IDE or editor like Notepad++ to edit your source files. You can use an older version of Visual C++ to edit the RC files, or Notepad or other tools.
If you want really want to make it slick, set up your IDE to run an "external tool" when you click a toolbar button, to have it run your command-line tools to compile + link (and optionally run the EXE file). You can probably find a debugger tool as well, but I haven't needed that yet, so haven't checked.
My best recommendation is to start the process of porting your code to Visual Studio.
You can use a library like OWLNext if you've used the OWL library in Borland.
The other alternative is is to use Windows Virtual PC (or other such virtual machine) to run Borland in an integrated Windows XP mode. See an example here.
This can be probable answer ???
You have to download configured Borland Compiler from http://www.4shared.com/get/Gs41_5yA/borland_for_graphics.html or http://dwij.co.in/graphics-c-programming-for-windows-7-borland-compiler/.
Put your Borland’s ‘bin’ folder into Environmental Variables.
Now go inside folder ‘bin’ & edit file bcc32.cfg as per your folder structure. This file contains settings of headers & libraries.
-I"D:\Borland\include;"
-L"D:\Borland\lib;D:\Borland\Lib\PSDK"
Now create any C/C++ Program say myprogram.cpp
Use following command to compile this bunch of code:
F:\>bcc32 myprogram.cpp
Congratulations !!!.
I have some code compiled using Visual Studio 2010 (C++), with Qt for the GUI and Phonon to show some videos.
I compile and run the code in a Windows XP machine and everything works fine. The videos and controls are shown correctly, and the same in other Windows XP machines. But at the moment that I try to use a Windows 7 machine, the video is not shown. Phonon controls are loaded, I can adjust the size of the Phonon VideoWidget but nothing is shown. I am using the SetFile method to indicate the file location and I have also tried (of course, with no luck) with setCurrentSource in the MediaObject (it works, though, in Windows XP).
I have tried different locations of files (absolute/relative) but nothing seems to work. Also, in XP when a video is not found an alert message is shown while in Windows 7 there is no error message, but also no video is shown. If I try to open the videos with other players, they work fine (I tried also with videos with different formats).
Any idea on what can be wrong? Is there something that I am missing with Phonon and Windows 7? Thanks!
When deploying your application to a different computer, make sure you don't forget to copy the Phonon backend. Not just the DLL contained in it (the ds backend for me), but also the directory itself.
That is
-Application Directory
¦-myexe.exe
¦-phonon_backend
¦-phonon_ds94.dll
Furthermore the Phonon backend on Windows (and Mac I think) makes use of the QtOpenGL module. So don't forget to copy this either. It can go inside the application directory.
In any case you could help yourself out a bit by adding a small bit of code that shows (perhaps writes to a file) which mimetypes are available. If it doesn't spit out anything, there is a problem with your backend. (Well, that of your application...)
This is what I had to do when I used Phonon to play video inside my application. Since I only quickly added this some time ago to my application, I'm not 100% sure that this is the only (or even the proper) way to do this, so anyone who has different insights feel free to comment on this.
