Answer

TGoMaps 1.5.0 is 99% compatible with the old versions. In the 1.5.0 version I have replace all "Extended" variables with "Double" variables to avoid a bug of Delphi 2006, 2007 and C++ Builder 2006, 2007.

So if you try to replace TGoMaps 1.5.0 in an old application (with a old version of TGoMaps) you will have compile errors.

To fix this problem there are 2 way:

  • If you don't use "Extended" variables into your project you can use Edit->Replace command of Delphi to replace all "Extended" variables with "Double" variables.
  • If you use "Extended" variables into your project you need browser all your code (don't use the Delphi Inspector) to find TGoMaps "Extended" variables and then replace them with "Double" variables.

 

For example you must convert this line:

procedure TMainForm.GoogleMaps1MapMoveEnd(Sender: TObject; CenterLatitude,
 CenterLongitude, North, East, South, West: Extended);

into this:

procedure TMainForm.GoogleMaps1MapMoveEnd(Sender: TObject; CenterLatitude,
 CenterLongitude, North, East, South, West: double);
