ActiveX question ...

[HadiRezaee]

Hi all,
I wanna write new Method for my ActiveX, like this:

LPCSTR GetText();

But in Class Wizard i can't write new Method with LPCSTR return value !!!
Can i change it in my source code ?

Hello,

I don't know Active-X-controls, but I think they are similar to a COM-server-dll (derived from IDispatch)... so I would try to declare the function as an Get-Method (of the properties your control contain) an change the LPCSTR for a BSTR (I think it works this way GetText [out, retval]BSTR *pbstr). I'm not quite shure if you have to use [in] instead...

I hope this is a hint...

Ditto on DonEsteban's advice. I too only know COM but I understand ActiveX is based on COM. I hesitated to answer in case someone knew that it was possible to do this in an ActiveX control.

In COM you can only return an HRESULT from a method. Anything else has to be a property and even then you are limite to BSTR types but these are easily convertible.
