Can some one tell me syntax to call myexe placed in system32 folder without mentioned drive letter in path of syntax.

something like "%systemroot%/system32...." exact way i do not know.

If I correctly understand what you are asking (and you have included windows.h)-- I think you should probably use GetSystemDirectory()
http://msdn.microsoft.com/en-us/libr...73(VS.85).aspx
You could also use CSIDL_SYSTEM with SHGetFolderPath()
http://msdn.microsoft.com/en-us/libr...81(VS.85).aspx
but for the system folder - I think it just calls GetSystemDirectory anyway

There are other ways to skin this cat tho'

Are you using one of the _exec functions to load and execute the new process? (or _spawn? -- or system()? )
In the largest number of cases the system32 folder will be in the path anyway and the exe will be found w/o a path.

i used following syntax and it is not calling my exe. please check whether it is correct or not, if not please correct it. Also i have not added windows.h

ShellExecute(NULL, NULL, _T("\%systemroot%\%\\system32\\me.exe"), NULL, NULL, SW_SHOW)

in case above syntax is correct should adding of windows.h will make it work.?

pls guide.

Ugh. How much experience do you have in C? You should know the answer to this question already.

Check the return value of the function - with this page. This will give you a hint of both the issue and where to begin looking to resolve it.

i m beginner. can u please tell me the right line to be added in stead of mine wrong line.

[mt2002]

I cant answer what is wrong without knowing what error it is returning.

Also, it is recommend to have good experience in C prior to going into the Win32 API.

i resolved . thanks for guidance.

one more query..

i used following and it is working..

ShellExecute(NULL, TEXT("open"), TEXT("me.exe"), NULL, TEXT("system32"), SW_SHOW);

but if i use following it does not

ShellExecute(NULL, TEXT("open"), TEXT("me.exe"), NULL, TEXT("system32\\drivers"), SW_SHOW);

can u guide on this? in second case i placed my exe in drivers folder.

I can't see the error messages but it is likely on vista that you (the program) don't have the privileges to run from this folder.

I am using xp sp3, and vs 2008.

I am not getting any error while building exe neither running exe , but the problem is that this exe not calling me.exe placed in drivers folder.
