From: Bee on 16 Feb 2010 15:07 I am using the API to open the color dialog. I would like to also open my own color dialog along side. (1) how can I lock the two together so if I move one, the other follows? or at least initially have them side by side or mine underneath? (2) how do I communicate from my dialog to the API common dialog. (a) to Close both from my dialog - i.e. send a cancel to the API if the user chooses my selection. (b)to put the selection from my dialog into the API Dialog custom colors?

You might want to re-think what you're trying to do. I can only vaguely envision what you seem to be trying to do...but it's scary. I have NEVER seen or even heard of 2 dialog boxes opening side by side. That just seems so wrong in so many ways. Why don't you explain what your ultimate goal is. Perhaps someone then can give you some advice. One can fathom that what you're wanting is for the user to be able to specify something additional that Windows' standard color dialog box doesn't provide. If you explain what that is, maybe someone can provide you an alternative to your current thinking. -- Mike

I gotta go with Mike on this one. The suggested design flys in the face of established and standard design, especially inasfar as modal windows go. You'll spend more time chasing bugs than offering functionality. Is it possible, certainly, but I'll bet some serious subclassing is involved. I'm not even sure if a common dialog could be subclassed in process in which case if it is not, you'd need a third party component to subclass out of process. In fact, I'm sure it will require such a thing. The obvious solution would be to roll your own color dialog to do what you want. There are a bazillion examples on the web. Start at planetsourcecode.com and search for "color dialog".

Basic concept would be to hook the dialog's message stream, then watch for and react appropriately to WM_MOVE, WM_MOVING, WM_SIZE, WM_SIZING. Main trick would be getting the handle for the dialog. Would probably be easiest to set a WH_CBT to watch for its creation. Questions? -- ..NET: It's About Trust! http://vfred.mvps.org |
