GetLastError always returns 0

[Idiota]

Hi. I have this in my program:

Public Declare Function CopyFile Lib "kernel32" Alias "CopyFileA" (ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal bFailIfExists As Long) As Long
Public Declare Function GetLastError Lib "kernel32" () As Long
Public Declare Function DeleteFile Lib "kernel32" Alias "DeleteFileA" (ByVal lpFileName As String) As Long

Just from the API viewer.

Problem is, when the copyFile or DeleteFile fail (they return 0) the getLastError function always returns 0!!! It's useless that way.

Do you have any idea?

Thank you very much,

Daniel

According to my reference, it says:

"Use the LastDLLError property of the Err object to obtain the GetLastError value in Visual Basic. This is necessary because VB sometimes resets the GetLastError value between the time the API call that generated the error returns, and the time your VB program continues."

Try that and see if it works,
