PA_Dial4DGetVariable

version 2003

PA_Dial4DGetVariable (dialog; variable) → PA_Variable

The routine PA_Dial4DGetVariable returns a PA_Variable embedding the value of the variable variable in the dialog referenced by dialog .

Note that it is probably much easier to use direct accessors to variable values, ie. PA_Dial4DGetDate , PA_Dial4DGetReal , PA_Dial4DGetArrayLong .

If PA_Dial4DGetVariable is called for a non-existing variable, the variable type is set to eVK_Undefined .

By default, variable needs to be a null terminated C string. If you have previously called PA_UsePStrings, you must pass a Pascal string to the command.

By default, variable needs to use Macintosh characters set on Macintosh, and ANSI characters set under Windows. You can call PA_UseMacCharacters or PA_UseAnsiCharacters to specifically use Macintosh or ANSI characters.

The handles received for Text, Pictures, and BLOBs belong to 4th Dimension. You should never dispose of them.

Check the value of "aVar", in the dialog dRef.

   PA_Variable   v;
 
   v = PA_Dial4DGetVariable( dRef, "aVar" );
   if ( PA_GetVariableKind( v ) == eVK_Longint )
   {
      if ( PA_GetLongintVariable( v ) == 3 )
      {
         /* . . . */
      }
   }
