Hi guys,
I'm using the Preferences Lib of PB. When I create a preference file,
CreatePreferences() returns 0. GetLastError_() returns 3. Does anybody
know WTF error number 3 is?

EDIT: Solved, I found this link: http://msdn.microsoft.com/library/defau ... _codes.asp

An easy way, for next time:

Code: Select all

ProcedureDLL.s ShowAPIError (CheckReturnValue) ; Forum code, unsure of original author
  Buffer.s      = Space (4096) 
  NumberOfChars = FormatMessage_(#FORMAT_MESSAGE_FROM_SYSTEM, 0, CheckReturnValue, 0, Buffer.s, Len(Buffer.s), 0) 
  ProcedureReturn Left (Buffer.s, NumberOfChars-2) 
EndProcedure

I think the original source of ShowAPIError() is:

another very short one :

Code: Select all

Macro LastErrorMessage() 
  Left(LastErrorMessage.s{4096}, FormatMessage_(#FORMAT_MESSAGE_FROM_SYSTEM, 0, GetLastError_(), 0, @LastErrorMessage, 4096, 0) - 2)
EndMacro

Macro LastErrorMessageRequester() 
  MessageRequester("LastError", LastErrorMessage(), #MB_ICONERROR)
EndMacro
