NOTHING procedure

BCX COM Interface

SET ... NOTHING procedure

Purpose: SET ... NOTHING procedure releases all memory resources allocated by call to CREATEOBJECT or by BCX_DISPATCHOBJECT functions.

Note well that NOTHING must be called for each created COM/ActiveX object otherwise memory leaks will occur!

Syntax:


 SET oBj = NOTHING

Example:


 CLS
 
 DIM app AS OBJECT 
 
 app = CREATEOBJECT("Excel.Application")
 
 IF BCX_COM_ERROR THEN 
 PRINT BCX_GET_COM_ERROR_DESC$ 
 END
 END IF 
  
 app.visible = true
 
 Sleep(2000) ' Excel will be visible for 2 sec, and than it will close.
 
 app.activeworkbook.saved = true ' don't prompt to save workbook
 
 app.quit
 
 SET app = NOTHING ' remember to call Set xxx = Nothing                  
                    ' to release resources used by COM object!!!
