Hi,

I encountered an FPC Win32, tutorial that uses the a declaration of variable "msg", declared as a MSG type, shown below.

Dev-Pas IDE, FPC 2.00 gives an "error in type definition" and I find no doc references to MSG, variable type. Was this an earlier convention in FPC and if so, how was it replaced?

Thanks,

Mike

program Win32_Source03;
uses  windows;
const
  AppName = 'Win32/ FPC - Source 03';
VAR
  active : BOOLEAN;
  msg : MSG;
  hWindow,msg : hwnd;
[end clip]

Previous version of fpc allowed this construct while newer not use Message:msg instead of msg:msg and rename msg in the line below of that.

Thumbs up Luiz, thank you.
The second usage with msg1 was a typo on my part.
Understandable that this was changed in the compiler. ;)

  active : BOOLEAN;
  mssg : MSG;
  hWindow : hwnd;
