Crash in Process.MainModule:"Only part of a ReadProcessMemory or WriteProcessMemory request was completed"

Question

Hi every one i have been using  Process.MainModule.FileName to get the filename of all the running processes in a windowsXP32bit application. It was working fine. But  the same 32-bit application crashed in 64-bit XP system giving the error as "Only part of a ReadProcessMemory or WriteProcessMemory request was completed".Sorry if i am repeating the same question which might have been posted long back. I am posting this because there were no solutions or work around methods mentioned in the forum......please give me any suggestions!

Answer 1

Are you sure it is crashing on the statement which contains Process.MainModule.Filename?

 

Did you build for "x86" or "Any CPU"?  If you did not try "x86", that is the first thing to try.

Answer 2

hi....actually the .exe is in C++ which loads a C# dll containing process related code .the .exe has only win32 and X64 configurations. For my default configuration win32 the targetmachine type option in linker is X86. My C# dll is set to ANYCPU

Answer 4

yes..can anyone test the following code and infer whats happening? ....Actually it works fine with x64 and ANYCPU configurations....but the requirement is it should work for an application built in x86 configuration and executed on x64 platform(it runs it under WOW).

 

Process[] procArr = Process.GetProcesses();

foreach(Process CurProc in procArr)

{

string FileName = CurProc.Mainmodule.FileVersionInfo.FileName;

string  version = CurProc.Mainmodule.FileVersionInfo.FileVersion

}

 

you can suggest even if there are any other alternate methods to get these informations

 

Thanks in advance.
