Hi All,
Good morning :),

Now my problem is solved, I am sending code for those who are facing the same problem.. :)

I am creating one MFC dialog based application and on click OK button I want to execute the other exe that is embedded in My resource file. Its a requirement.
What i do is:
I added other exe as a custom resource:
Than on OK button, I load that resource and get the handle of that resource.
Now I am stuck how to execute that executable using handle...
My code is :

/////////////////////////////////////////////////////////////////////////////////////////////////
// TODO: Add your control notification handler code here
	HRSRC		hSource = NULL;
	int			nSize   = 0;
	HGLOBAL		hGlobal = NULL;
	LPVOID		lpVoid  = NULL;
	hSource = FindResource(NULL, MAKEINTRESOURCE(IDR_EXE2), _T("EXE"));
	if(hSource == NULL)
	{
		HWND hWnd = m_hWnd;
		MessageBoxEx(hWnd, _T("FindResource() Failed\t"), _T("Error Message"), MB_OK | MB_ICONSTOP, LANG_ENGLISH);
		return;
	}

	hGlobal = LoadResource(NULL, hSource);
	if(hGlobal == NULL)
	{
		HWND hWnd = m_hWnd;
		MessageBoxEx(hWnd, _T("LoadResource() Failed\t"), _T("Error Message"), MB_OK | MB_ICONSTOP, LANG_ENGLISH);
		return;
	}
	lpVoid = LockResource(hGlobal);
	if(lpVoid == NULL)
	{
		HWND hWnd = m_hWnd;
		MessageBoxEx(hWnd, _T("LockResource() Failed\t"), _T("Error Message"), MB_OK | MB_ICONSTOP, LANG_ENGLISH);
		return;
	}
	nSize = (UINT)SizeofResource(NULL, hSource);
	SaveExecutableAndExecute((BYTE*)hGlobal, nSize);
	

	UnlockResource(hGlobal); // 16Bit Windows Needs This
	FreeResource(hGlobal); 
////////////////////////////////////////////////////////////////////////////////////////

void CEmbedExeAsResourceDlg::SaveExecutableAndExecute(BYTE *pBuffer, int nSize)
{
	HGLOBAL hGlobal = GlobalAlloc(GMEM_MOVEABLE, nSize);
	if(hGlobal == NULL)
	{
		HWND hWnd = m_hWnd;
		MessageBoxEx(hWnd, _T("Can not allocate enough memory\t"), _T("Error"), MB_OK | MB_ICONSTOP, LANG_ENGLISH);
		return;
	}
	void* pData = GlobalLock(hGlobal);
	memcpy(pData, pBuffer, nSize);
	GlobalUnlock(hGlobal);
	
	CStdioFile m_OutPutFile;
	// For testing purpose only I am using the hardcoded path.... 
	m_OutPutFile.Open(_T("c:\\sample.exe"),CFile::modeCreate|CFile::modeWrite|CFile::typeBinary);
	m_OutPutFile.Write(pData,nSize+1);
	m_OutPutFile.Close();
	GlobalFree(hGlobal);
}

Thanks in advance ....

Do you have any solution?? My requirement is that I have to embed an Executable in my resource file and than execute it. Its an R&D for me ...
If you have than please suggest me :)

You already said that you have the solution, so was that not correct? I doubt that there is a real solution to what you are trying to do since it is a rather futile exercise. Why embed an executable file as a resource in another application just so you can run it? Just run the original application normally and dispense with all this unnecessary wrapping.

Yes I understand :)
Reason: There is one VB.net executable that user want to run on Windows 7 and later version but if it is executed on XP than it crashes because to execute this application some framework is to be present in system. In Windows 7 it is present by default but in XP it is not.One solution is we can create a vc++ application that first check that is OS is Windows 7 or not. If it is not than just display a MessageBox and exit, else execute that executable. It is a worst case scenario but if we do not find any solution than we can do by this.

I have never tried this but the Windows LoadLibrary()[^] function may be able to assist.
