Re: [platform-swt-dev] Re: Problem in Caturing excel events form SWT
|
Hi,
I need to capture following events.
1)SheetActivate
[helpcontext(0x00010619)]
HRESULT _stdcall SheetActivate([in] IDispatch* Sh);
2)SheetChange
[helpcontext(0x0001061c)]
HRESULT _stdcall SheetChange(
[in] IDispatch* Sh,
[in] Range* Target);
3)SheetDeactivate
[helpcontext(0x0001061a)]
HRESULT _stdcall SheetDeactivate([in] IDispatch* Sh);
4)SheetCalculate
[helpcontext(0x0001061b)]
HRESULT _stdcall SheetCalculate([in] IDispatch* Sh);
I think this is what you are looking for.Since I am new to COM I dont
know much about IDL .
