Dave Sanabri #1 / 3	set the MDI parent of MDI child forms that are in a DLL -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am trying to architect an application that will be developed in parallel across a team of programmers. Each programmer will be tasked with developing an testing their components, which will have forms etc. The problem that I have found is that an MDI form in a DLL doesn't know about the MDI parent of the primary application, and thus generates an error. There is an API called SetParent which I unsuccesfully tried to use. I have not tried to use the RegisterClass method yet becuase I am developing a prototype that need to function by tomorrow: Private Declare Function RegisterClass Lib "user32" _ Alias "RegisterClassA" (Class As WNDCLASS) As Long If anyone has doen this before, I would appreciate some insight into how this is accomplished. CC by email would be appreciated.

galen nickerso #2 / 3	set the MDI parent of MDI child forms that are in a DLL Dave, I've seen this bounced around quite a bit and every attempt always seems to involve a few glitches. It's probably not the answer you want but I've been able to do this with no problems using Stingray's OT/X: http://www.stingray.com/otx/default.asp '------ galen Quote: >-----BEGIN PGP SIGNED MESSAGE----- >Hash: SHA1 >I am trying to architect an application that will be developed in >parallel across a team of programmers.

Dave Sanabri #3 / 3	set the MDI parent of MDI child forms that are in a DLL -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have received two responses thus far, and would like to report my findings to the group: It _is_ possible to use the SetParent API function to set the MDI parent of an MDI child from a DLL. The child DLL needs to return some value (a reference to the form, or other value) that the parent MDI can use to get the child's hWnd (window handle) in order to use the SetParent method. Acording to "cbarrett" there is a great article in the March 1999 edition of Visual Basic Programmers Journal (VBPJ), but you would have to subscribe to get it since most news stands are still carrying the February edition. Clearly, this is an important issue, which I will continue to follow up on until I am comfortable with the answer to my question. I would encourage fellow practictioners to contribute to this body of knowledge so that we may all benefit. Regards, Dave Sanabria Programmer PRT Group, Inc.
