How to find out the type of an executable file, i.e. whether it’s a windows application or a console application or an MS-DOS application…
void GetFileType( LPCTSTR lpctszFilePath_i, CString& csFileType_o )
{
// Get exe file type
const DWORD dwRetVal = SHGetFileInfo( lpctszFilePath_i,
FILE_ATTRIBUTE_NORMAL,
0,
0,
SHGFI_EXETYPE );
if( dwRetVal )
{
/*
READ THIS!! dwRetVal is interpreted as follows...
LOWORD = NE or PE and HIWORD = 3.0, 3.5, or 4.0 Windows application
LOWORD = MZ and HIWORD = 0 MS-DOS .exe, .com, or .bat file
LOWORD = PE and HIWORD = 0 Win32 console application
*/
const WORD wLowWord = LOWORD( dwRetVal );
const WORD wHiWord = HIWORD( dwRetVal );
const WORD wPEWord = MAKEWORD( 'P', 'E' );
const WORD wMZWord = MAKEWORD( 'M', 'Z' );
const WORD wNEWord = MAKEWORD( 'N', 'E' );
// Read above comments to understand what's happening
if( wLowWord == wPEWord || wLowWord == wNEWord )
{
if( wHiWord == 0 )
{
csFileType_o = _T( "Win32 Console Application" );
}
else
{
csFileType_o = _T( "Windows application" );
}
}
else if( wLowWord == wMZWord && wHiWord == 0 )
{
csFileType_o = _T( "MS-DOS .exe, .com or .bat file" );
}
else
{
csFileType_o = _T( "Unknown file type" );
}// End if
}// End if
}// End GetFileType
