Erick Larso #1 / 3	Wha'ts wrong with this code In vb 5.0- Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) I get a "Bad DLL calling convention error" at the following line: hwndMT = FindWindow(vbNullString, MsgTitle) I'm trying to activate a 16-bit application and have tried: Private Declare Function FindWindow Lib "user" (ByVal lpClassName As Any, ByVal lpWindowName As Any) but this gives this same error. Any ideas? TIA
