Forcing Form in ActiveX DLL to MDI

[RichardF]

Hi,

(using VB6)

I have a form which sits in a DLL which in turn is accessed through methods of the class ShowGenericForm.

If in the DLL i set the MDIChild property to TRUE and call the method ShowForm in a client MDI app then i get Error "No MDI form available to Load".

However, if in the DLL i set the MDIChild to FALSE and pass the HWND of the MDIParent form to the ShowForm function as a parameter then i can use the SetParent api to 'Force' the form to 'become' a MDIChild. (Assuming inside the function i find a window with the class MDIClient as this is the true parent of MDI Child forms).

I am interested to know if doing this could break something else ? Does anybody see a problem with this ?

RF.

Hi Richard,

Did you ever get a good response to your question here. I have found two activex components that say they do it. See

and

C:\Documents and Settings\jmcguire\Local Settings\Temporary Internet Files\OLK3B6\ComponentSource - Product Page forMDIExtender.htm

Have you come across a way to have an MDI parent form within an activex dll?

thanks
