attach
Connecting to a third-party Windows program through the OLE mechanism using the GetActiveObject function.
In this case, we can connect to an already open program (for example, to the current Excel spreadsheet).
Call:
int iret = ts_idispatch(int iIDispatchApp,"attach",string appclassname);
Here:
iIDispatchApp - descriptor of the ts_idispatch object where the created program object will be placed;
appclassname - class name of the program object ("Excel.Application" - for Excel);
