Hi, I'm trying to do the following:
From a regular InstallShield dialog, I have a "browse" button and an edit box. When I click "browse", a DLL dialog opens and lets me make some choices. When I click "ok", I want the choices I've made to appear in the edit box.
The problem: Inside the DLL, I call "msiSetProperty" to change the property that is associated with the edit box, but since the edit box doesn't get refreshed, I don't see the changes reflecting on screen (unless I go "back" and "next" again). I've tried passing the MsiWindowHandle as a HANDLE|Constant, and call UpdateWindow(...), but it keeps coming in NULL to the DLL. Any ideas on how to refresh the dialog (or to make the handle come in !NULL) ?

To the best of my knowledge, there is no way to update the value on a dialog, without going backwards and forwards.

A common workaround is to create an identical dialogue, then load that one when you want to refresh the value.

Not acurate. It is very much possible to update the text in the edit control box, using SendMessage(WM_SETTEXT.....). I've done it and it works. I'll send you the source code if you like... The only problem is that in order to find the edit control, I have to first enumerate all windows in the system and find InstallShield's window. I don't want that - I want to be able to pass the window handle - but it always comes in NULL. Do you know who to pass it correctly?
