loading registry file programatically

act_x

I attempted to do this in a DLL and it worked just fine . However moving the code inside COM exe does not report any error but does not load the information in the registry .

STARTUPINFO si;
PROCESS_INFORMATION pi;

	ZeroMemory( &si, sizeof(si) );
	si.cb = sizeof(si);
	ZeroMemory( &pi, sizeof(pi) );		
	//strLocalFileName = "/a " + strLocalFileName;
	CString strLocalFileName = CString(\_T("regedit.exe /s ")) + strRegFileName;

		// Start the child process. 
	if( !CreateProcess(  NULL,   // No module name (use command line)
		strLocalFileName.GetBuffer(0),      // Command line
		NULL,           // Process handle not inheritable
		NULL,           // Thread handle not inheritable
		TRUE,          // Set handle inheritance to FALSE
		NORMAL\_PRIORITY\_CLASS,              // No creation flags
		NULL,           // Use parent's environment block
		NULL,           // Use parent's starting directory 
		&si,            // Pointer to STARTUPINFO structure
		&pi )           // Pointer to PROCESS\_INFORMATION structure
	) 
	{
		//AfxMessageBox("Error Creating Process");
		int error = GetLastError() ;
		CloseHandle(pi.hProcess) ; 
		return false ; 
	}
	else
	{
		ATLTRACE("GetLastError = %d\\n",GetLastError()); 
		WaitForSingleObject( pi.hProcess, INFINITE );
		DWORD dwCode = 0; 
		GetExitCodeProcess  (   pi.hProcess,    &dwCode);
		CloseHandle(pi.hProcess); 					

	}

Any help is appreciated !

Try specifying some value other than 0 for si.wShowWindow. That way you can see if an error is popping up (and quickly disappearing).

This looks strange:

ZeroMemory( p, sizeof(pi) );

act_x

so basically I am trying to create a process to run

regedit /s C:\Program Files\Common Files\MyApp\1.reg

For debugging purposes I removed the /s for regedit and I see that it chops the path by space So it keeps asking if I want to enter the entry C:\Program Files Common Files\MyApp\1.reg Is there a way this can be prevented ? These files are present in the current working directory of the exe and pro grammatically obtained via GetModuleFileName

thanks for steering me into resolving this . The key was to enclose the file path in quotes before supplying it to regedit. But I wonder why and how this would be different in a DLL that I developed .
