Hi emi_sastra,

You can do something like:

Dim fi As New FileInfo(MyFileFullPath)
If fi.Extension = ".bmp" Or fi.Extension = ".jpg" Or fi.Extension = ".png" Then
  ' valid file
End If

Of couse someone could rename to that but if thats the case you can try to load it (in a different function using a error handling tho catch error) and check if it's valid. But this is heavy for the your application/system.

I don't care its extension and I've already check its existing.
Could you please provide code how to check it as you mentioned?

Thank you.

Try this:

Private Function ValidPicture(ByVal filename As String) As Boolean
  Dim pb As PictureBox

     Return True
  Catch ex As Exception
     Return False
  End Try
End Function

End Function

Then you can use it this way:

If ValidPicture("c:\abc.bmp") Then
  ' valid picture
End If

Hope this helps
