if it's not executing, how can it return 32 ?

maybe you just don't see the windows because of the SW_HIDE. what if you display it with SW_SHOWNORMAL ?

also, how do you check the return code ?

I am receiving the returning value in an integer. It is executing but giving me the error 32 "process can not access file because it is being used by another process."

CString csFilePath = _T("D:\\myFolder\\mybat.bat"); //contains the path of my bat file.

int iReturn = (int)ShellExecute(NULL,_T("Open"),csFilePath,NULL,NULL,SW_SHOWNORMAL);

In MSDN it is written that if iReturn is greater than 32 then shellexecute() is successfull and if it is less than 32 then unsuccessfull.

and I have written the error message already to you.

and so, the message doesn't talk to you ?
What it means is perfectly clear to me. maybe you should read it again Wink | ;)

You could use Process Explorer[^] and close the handles of the applications using this file...

Anyway Dear sir, may be I am wrong or doing some fault in code.

My problem is only that how can I execute a batch file in vc++?
I am not concerning only in Shellexecute(), if there is any other way, please guide me.

exactly the way you do !

if you had ask me to launch a .bat from my exe, I would have written the same code for sure !

Madan Chauhan wrote:

yes, there are, but i find them not as much elegant than ShellExecute(), and this cannot be the reason.
The reason is (as the error message said), that some file is being used by another process (another application. use ProcessExplorer (very lightweight) to find which is the culprit...

Your statement is baseless. No program will be allowed to create or modify registry entries if it was not run with administrative privileges.

You need to specify that in your application's manifest file. These references may be of help to you:

Create and embed an application manifest (UAC)[^]

Least privelege: Teach your apps to play nice with UAC[^]

Specifying the privilege elevation[^]
