GetFileVersionInfoSize
The GetFileVersionInfoSize
function determines whether the operating system can obtain version information
about a specified file. If version information is available, GetFileVersionInfoSize
returns the size in bytes of that information.
As with other
file installation functions, GetFileVersionInfo works only with Win32
file images. It does not work with 16-bit Windows file images.
DWORD GetFileVersionInfoSize(
|
LPTSTR lptstrFilename, |

Parameters
lptstrFilename
Pointer to a
null-terminated filename string that specifies the file of interest.
lpdwHandle
Pointer to a
variable that the function sets to zero.
Return Values
If the
function succeeds, the return value is the size in bytes of the file s version
information.
If the
function fails, the return value is zero. To get extended error information,
call GetLastError.
Remarks
Call the GetFileVersionInfoSize
function before calling the GetFileVersionInfo function.
