I have a problem to load a videofile. I am using Visual Studio 2010 and OpenCV 2.4.6.
Sometimes it loads video properly and sometimes it won't, although it is the same file and the same code (Nothing has changed). So basically, one day it works and the next day does not. I noticed some strange behavior BEFORE.
When I run the code I get Unhandled exception
and then No source available
A few weeks ago I wasn't able to open a video in one of my project. The problem was that if I opened a project from pinned Start menu than the video couldn't be loaded.
BUT when I opened a solution right from a directory than video was loaded properly. I couldn't believe so I tried this more times.
However, in either case it does not work this time.
ALso, I tried to run Visual Studio as admin. Nothing.
What could be a problem here?

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.
This is slowly driving me crazy. It is a problem I did not have with VS2015 and only showed up when I started using VS2017. I have upgraded to the first service pack and that did not change anything.
It is a C# .NET Core project if that matters. Any time I create a new file (e.g. Foo.cs) it doesn't seem to get associated with the solution. If I try and reference it from an existing file then the IDE doesn't recognize it and it reports an error. Any open tabs I have with these files shows them as "Miscellaneous files" where it would normally have "ProjectName(netcoreapp1.1)".
If I close the solution and then reopen it then everything works fine. Building or rebuilding the solution does not fix the issue. Is anyone else seeing this problem?
Trying to compile a VS 2013 C++ application and Im getting the LNK1168 cannot open .\bin\foo\bar\foobar.exe for writing.
I've followed other articles. Application Experience is enabled and running. Ive restarted VS. Cleaned and tried to rebuild. Checked the Task Mgr to make sure the application isn't running too.
My only success is after a full system reboot.
Nothing is working except the system reboot. I went to the directory and noticed that when I tried to delete the .exe that is currently there (from a previous successful build) it gives me an error saying that the operation cannot be completed because it is open in Windows Audio..
Has anybody dealt with this before? Restarting my whole OS to build is not going to work for me much longer.
The project is mapped to a D: drive (i.e. not located on C:).
I have Windows 10, fully updated.
I downloaded and installed Visual Studio Community 2015 last week for the first time, (previously programmed in Code:blocks, still installed) and selected custom install to allow for C++ and Python programming.
Installation ran smoothly, but VS always fails on launch.
On first launch ever, it said it was setting things up for first startup; asked me for sign-in which I did, at which point it briefly showed something about my profile before saying 'An error occurred while starting for the first time. Please restart Microsoft Visual Studio'. Imgur images of all dialog boxes here, including parts of a processmonitor log I estimated to be around the general time of the error.
Closing and restarting several times didn't help.
Uninstalling and re-installing didn't help.
Rebooting didn't help.
And uninstalling, running Ccleaner's Cleaner and Registry Cleaner, rebooting computer and re-installing VS didn't help either.
Repairing the install from Programs also didn't help.
I managed to find the exact same error on Google Search for VS 2013 but the only solution was where one person got a completely new OS and re-installed VS on that.
I tried the other suggestions they had including running:
devenv.exe /safemode
devenv.exe /resetskippkgs
devenv.exe /resetuserdata
devenv.exe /installvstemplates
devenv.exe /resetsettings
the first 3 took me to the same sign-in screen. Regardless of signing-in or not, or running VS from the Administrator Profile or not, these option always give the same failed on first startup error.
Installvstemplates gives an error saying the operation could not be completed, but /resetsettings finally got me into VS.
That's about all it does though, I can go to the home page and access options/menu buttons, but signing-in makes it crash and reload again (but it does sign me in and take me to the home screen)
Signed-in/not and Administrator or not, VS crashes on opening a new .cpp file.
When I click Start a New Project I get "Error loading type library/DLL.(Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)). Closing VS and trying to open it normally from start menu still always throws the original error, despite working if I open it via /resetsettings.
I've also checked [HKEY_CLASSES_ROOT\CLSID{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32] in Regedit and found it is apparently correct.
I also used devenv /log to generate an xml file of the process when I open it.
Just to mention I have .NET Framework 4.5-4.6 installed with VS as well.
Looking forward to any advice.
So, for anyone else getting the same problem, I haven't gotten any other advice, since this post.
If you're still having probs # this point the only real solution seems to be a clean install of your OS .
I can confirm it solved all my issues, with VS + some OS problems I wasn't aware of . I can only assume they might've been related, good luck.
Working on a Win32 DLL using Visual Studio 2008 SP1 and, since yesterday, whenever I try to right click on code, to go to a variable definition for example, VS completely locks up and I have to manually kill the process. To make it even weirder, whenever this happens the devenv.exe process uses exactly 25% of the CPU. And I mean exactly, never 24%, never 26%, always 25%
Also, I've run ProcMon to see if devenv is actually doing something, but it's doing absolutely nothing external of the process. No disk, network, registry access. Nothing.
This is getting really aggravating because I have a large code base to deal with and the only other way of jumping to the definition is to first search for it.
Has anyone run into a similar issue? And, better yet, know a fix?
Edit: More info. Other projects (even an older version of the same one) work fine. I diffed the project file and the only differences is added source files and a /D define in the command line params.
Edit 2: So, it seems that now it's actually because intellisense is stuck updating. For some reason the status bar was disabled, but when getting it back I say "Updating Intellisense... (186)" and from what I've read, that 186 means that there are 186 background threads working. 186?! But, procmon still shows no IO whatsoever.
Try deleting all .sbr .bsc and .pdb files.
For the 25% CPU load: I guess it uses one core on your quad core machine.
If you have Visual Assist installed, try disabling it.
On connect, a submitted bug: Visual Studio Hang, seems to closely resemble your issue:
At random times, when I right click in the text editor, in this case C/C++ editor, Visual Studio will just hang. And if I wait it out, it still hangs.
It seems the workaround is to exit Visual Studio and delete the intellisense (.ncb) file in your project directory and reopen it.
The issue you are seeing is an intermittent failure in prior versions of Visual C++ that is hard to diagnose, and has a relatively simple workaround, as you have discussed, which is to delete your NCB. In order to get proper intellisense for header files, they would need to be included by a .cpp file in your project (directly, or indirectly through another header.)
