32bit and this statement can not be running on 64bit system. I wonder why this happens, and why the system thinks that I am running on a 64bit OS? The code I use: HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPid); if (hProcess) { HMODULE hMod = NULL; DWORD cbNeeded = 0; if (EnumProcessModules(hProcess, &hMod, sizeof(hMod), &cbNeeded)) { //do something here... } } dwPid is the id of the process I want to manipulate.

fine.

Which is it? Both of those return BOOL, so I'm not sure what "returned with error code 299" means, either. Do you mean "After it fails, GetLastError returns 299"? Please edit your question to include your code and to be more clear about what you're asking. –Ken White May 27 '13 at 6:07 sorry Ken, my fault –ericchan1336 May 27 '13 at 6:12 Well, you got half. Thanks. :-) Once again, please include your code. It's very difficult to say what might be wrong if we can't see what you're doing in the first place. –Ken White May 27 '13 at 6:14 I feel like I'm pulling teeth here. :-) There's no call to GetLastError in the code you posted, so there's no way you got a 'error 299' with this code , which means it's not the actual code you're using (or your question is made up in the first place). If you want help, post your code so we can help. –Ken White May 27 '13 at 6:32 3 From MSDN: If this function is called from a 32-bit application running on WOW64, it can only enumerate the modules of a 32-bit process.

You only pass 1, not big enough. Note the lpcbNeeded, it tells you how large the array needs to be to not get the error. share|improve this answer answered Aug 5 '11 at 20:53 Hans Passant 653k819571601 Holy mackerel I missed that by a mile thanks. –Daniel Lopez Aug 5 '11 at 20:59 add a comment

I am trying to get the Application Name and Path from the Window Handle The reason is explained in: enumprocessmodules error 299 http://msdn.microsoft.com/en-us/library/ms682631(v=vs.85).aspx I think the only solution is a 64 bit DLL or COM object which can be called from a 32 bit application. Are you aware of such a component. 0 Question by:GHG-RCH Facebook Twitter LinkedIn Google LVL 32 Best Solution byewangoya I had to do some research on this. Basically the size of the pointers is the problem. However you can use GetProcessImageFileName and that will get the path for the 64bit processes as well.
