i am new in using the Visual Leak Detector, after creating the settings as per the documentations for Visual C++ 6, and running the program in the debug mode
the error
"The application has failed to start because vld_x86.dll was not found.Re-installing the application may fix this problem"
i have reinstalled and included the path for the dll in the VC6 settings.
thanks in advance for the help.
After searching for the answer myself for quite a long time, two things finally corrected the problem for me. First, if you haven't already restarted Visual Studio after including these new files and libraries, then you should do so. Second, when I went to look into my computer to see what was added to my path in environment variables, it had add the win64. and I run win32. Hope that was descriptive enough and helps.
the include is correct and needed as far as i know.
i was having the same problem and could solve it by copying all files in vld's "bin" directory into the same folder as the executable i wanted to check for leaks.
not a very elegant way but working, i hope it works for you aswell!

we made one application on Visual Studio 2008 , it about to release. but now we are getting the crash while launching the application . could you please any give a suggestion how do i debug on this particular issue
You can run the Release build in the debugger, too. Turn on debug-info settings in both the compiler and linker tabs (I think that was not the default in vs2008 and there were two distinct places to set) but don't change any optimization options or other setting.
Then launch the program from the debugger. If the resulting EXE shows the crash when run normally but not when started via the debugger, there are more things to make the situations work the same (and that shows clues as to what is wrong, too). So let us know if that still doesn't reproduce.
There could be a lot of reasons for your application's Release is crashing.
Did you link proper Release libraries with your application in Visual Studio project configuration ?
Check your code for some missing Release specific code.
My best guess is you are not linking to proper libraries for the Release version of your application.
Also, one reason could be that your application may be trying to load some file that may not exist. This happens with me sometimes when my Release build of application does not find file that it needs (Eg: OpenGL application trying to load a shader file that is missing); and you don't check for errors.
when i try to run a application developed in vc++ on windows7,i get popup window saying that"the program can not be started because MSVCR80D.dll is missing from your computer,try reinstalling the program to fix this issue."
I googled it,it says that this DDL may not be present in your system or it has been got corrupted,Now i searched this file, i get this file at 20 different folder in win7.
I am not getting which file has been corrupted or if it is missing then where it is mising?
can anybody tell in which folder ,this DDL is missing or might be corrupted?
Thanks in advance. .
You're trying to run a Debug version of your program on a machine which does not have VS installed. The MS*D.dll files are not redistributable - they are installed were VS is installed. If you want to run executables on other machines, compile them as Release. You might still need to deploy some files (depending on how you're linking to the CRT), but that won't be a problem.
Never ever distribute your DEBUG builds to customers. Always distribute Release build.
Yes, of course, in develoment environment having multiple machines, you may share Debug builds to other developers - provided others developers have debugging-tools (like VS) installed on their system along with Debug-binaries of shared DLLs (like MSVCRxx).
Are you using the same computer that compiled the program? If not, you need visual studio redistributable files to run it.
Search the internet for your version of visual studio or visual c++ redist, you'll find it.
I'm trying to use OpenCV in Visual C++ express edition 2008. I've installed OpenCV 2.1 and added necessary include and lib directories/files to my project dependencies. A system PATH is also present for "C:\OpenCV2.1\bin".
When i compile and run the example program to open an image, I get a runtime error saying cxcore210d.dll is missing. I checked the bin folder and its there.
I've looked at similar posts here and on Google and they suggested turning off incremental linker. This didn't change results.
Please help
thanks
I just had to restart my PC. I'm guessing without a restart some variables are not registered correctly. :s but now this runs fine.
If anyone is working with OpenCV, so get in touch.
Thanks
The "d" stands for a debug build. You need to compile the OpenCV library with "debug" options set. Unfortunately, I don't think you can do this with Visual C++ express edition. I've tried it before...
why not you copy your dll into the folder and beside the application.
hey i just solve this problem. copy cxcore210d.dll and highgui210d.lib from your bin folder and paste it in lib folder and see the result...
Unfortunately this is going to be a pretty open-ended question, but I am at my wit's ends and I thought I would reach out for some advice.
This is a Visual C++ MFC app using Visual Studio 2008 SP1.
A coworker and I both had Office 2007 installed and we have both had strange DLL loading problems with our app since. Specifically, LoadLibrary is failing to load one our DLLs ( the first one it loads ) and returning error code 126 ( module not found ). What's really strange is that if I just run the executable from the windows explorer it works fine.
I took the usual steps to diagnose the problems:
Verify that the file existed and that the current working directory was pointed at it.
Run dependency walker and verify that it's dependencies are loading correctly. They are all loading ok except the ones this question says are ok to fail.
Experiment with loading some different DLLs at the same location in the code. Some of the simple 'stub' dlls succeed, but most of them fail.
Experiment with loading the DLLs that are failing from separate test apps - in an empty console app and a barebone MFC app, all the DLLs are loading fine!
Try to load the DLLs with LoadLibraryEx and the LOAD_LIBRARY_AS_DATAFILE flag, which does succeed but doesn't get us very far except to point out it's probably a dependency problem.
I really don't know what else to do at this point. Like I said, Office 2007 is a common thread in our problem but I don't know what kind of problems it could create. I really don't know even what steps to take next. Any ideas?
edit: I'm pretty sure the current working directory is not in the DLL path for some reason. It seems the DLLs that are failing are ones that need any other DLLs. If I turn on Loader Snaps debug output the current working directory does not appear to be in the DLL loading path. Any idea what could cause this?
edit2: The current build dumped the executable into a directory other than the working directory. For some reason, when I tried to load a DLL which then tried to load ANOTHER DLL, the current working directory is no longer searched. By putting the executable into the directory with all of the DLLs I am trying to load, the problems go away. Based on all of this, and the output by loader snaps, I am 98% sure this is some bizarre Visual Studio bug and I will simply have to work around it.
Office 2007 turns on SafeDllSearchMode in the registry.
http://msdn.microsoft.com/en-us/library/ms682586%28VS.85%29.aspx
With SafeDlLSearchMode, the current directory is no longer searched. To disable it, they claim you can go into regedit and set HKLM/System/CurrentControlSet/Control/SessionManager/SafeDllSearchMode to 0, but this did not work for me. Calling SetDllDirectory to the current directory DID work for me, although this only works if you are targeting XP SP1+.
The reason this caused problems in my specific app is that when we run the executable from the debugger, we keep the executable in a different directory than the current directory with all the other build files. When we run outside of Visual Studio, we first copy the executable into the directory with all of the other DLLs. The directory that the original executable is called from is ALWAYS in the search path, so if you keep your executable and your dlls together, you would never run into this problem.
Still, it's quite confusing for Microsoft to change the dll search path under us like this.
Does the DLL which fails has MSVCRT80 in dependencies? If yes, the most likely reason is that Office 2007 has overridden MSVCR80.dll
We have an installer application.
In that we have one dll related to our application.
We created setup with all respective files.
We used "Install Shield 6.3" and created a setup file.
After created build. The build is working in xp, not working in 2000.
It is showing error message as Couldn't load .dll only in win2000.
What could be the issue any idea?

It looks like one of the system/third party dll you are loading is either not available or of wrong version. Use a tool like dependency walker to check whether all the required dlls are available or not.
You have probbely missing prequsits that exits on XP but not on Win2000.
You need to run the Dependency Walker tool on Win2000 and load the problematic DLL, the tool will tell what is missing.
Try running installation with Filemon in the background, filtering with the missing DLL's name. Then, see where the DLL is searched for, and fix the problem. Hard to say without any further information, but first difference I have in mind is that the system folder in XP is C:\windows\system32, while in win2000 it is C:\winnt\system32. If you've hardcoded the system path for any reason, it might be the problem.
