Current coordinates system value (using WCSetCoordinateSystem function) : Clipper

Application Development · #1 11-03-2008, 12:23 PM

Hi VO'ers,

I need to use the WCSetCoordinateSystem() function with True
parameter to change the coordinates system.

I would like to keep the old value od the coordinates system to
be able to restore it after my code but it seems that this
function return the value you assign as parameter and not the
current one.

(Note : this is used in a library and I cannot know what the
developer used in the main application)

Here is my example :

myCurrentCoordSystem := XXXXX // Here is the problem !

WCSetCoordinateSystem(True)

..
..
..
my code
..
..
..
WCSetCoordinateSystem(myCurrentCoordSystem)

Do you have a tip for it.

TIA,

A quick search of the VO27 SDK suggests
WCGetCoordinateSystem()

Thanks Malcom,

I know that WCSetCoordinateSystem() was an hidden function but
never heard about WCGetCoordinateSystem()

BTW I could guess :-)

Thanks.

Does not look to be very hidden in the SDK...

I meant it's not listed in the help file.
