Syntax

CALL NOTIFY(OLE-object-name,'_COMPUTE_',in-OLE-method<,in-parm...,in-parm>,out-value);

CALL SEND(OLE-object-id,'_COMPUTE_',in-OLE-method<,in-parm...,in-parm>,out-value);

Argument	Character (C) or Numeric (N)	Description
in-OLE-method	C	specifies the OLE method name.
in-parm	C or N	provides a parameter to the OLE method.
out-value	C or N	contains the value returned by the OLE method.

Details

The _COMPUTE_ method invokes a method (with parameters) that is exposed by an OLE automation server. The number of parameters (in-parm arguments) needed varies among different objects and methods. Only methods that have a return value should be used with the _COMPUTE_ method. For methods with no return values, use the _DO_ method.

Examples

The following example stores the contents of the item in position 2 of an OLE control in the variable item2obj:

length item2obj $ 200;
call notify('oleobj', '_COMPUTE_', 
            'GetItem', 2, item2obj);

The following example uses the cells method of a spreadsheet object to compute the location of the cell at row 2, column 5, and then sets the value of that cell to 100:

call send(oleobj, '_COMPUTE_', 'Cells', 
          2, 5, cellobj1);
call send(cellobj1, '_SET_PROPERTY_', 
          'Value', 100);
