Simple OCX -- Having Problems

[Randal Lanning]

Hi all, I hope this is the right place.

I've got a small OCX with only about four functions. I've run both the TypeLib and the COM Browser to generate the include file and they give me the same thing. Using Jose's OLE wrapper, I was able to get it to display the control on a modal dialog.

There are no compile errors however when I get the OBJRESULT back it's &H8000FFFF which comes back with the message "Catastrophic Failure". That tells me nothing. Without further adieu, I'm posting the code to see if anyone can figure out what I might be doing wrong.

Thanks,

Stone

When using my OLE container to host the OCX, you don't retrieve a reference to the dispatch interface using:

Code Select Expand


' Get the IDispatch of the control
Hap = newcom $PROGID_ACTIVEHAPTEKXLib_ActiveHaptekX1


but

Code Select Expand


LOCAL hCtl AS DWORD
CONTROL HANDLE CB.HNDL, %ID_Haptek TO hCtl
Hap = OC_GetDispatch(hCtl)

Hey Jose,

Has anyone ever told you that you are a genius? It works perfectly!!!

Thank you so much!
