Docking a toolbar at specified position

We allow a single toolbar docked at the top of our app under the ribbon. We want the out-of-the-box position of the bar to be centered wrt the frame.

I found the toolbar GetToolbarInfo (and Set...) APIs. Even though they are public, they are useless since the returned structure is not public. I'm not sure if will even help if I had access to the structure. I have found when I save the command bars, CJ writes an "xPos" and other data into the registry for the bar.

So I thought perhaps I could "seed" the registry on the first run of the app and get the bar to move over. But, I have found that even if I manually edit the xPos value in the registry, the bar doesn't move. If I move it dynamically by dragging it and save the bar layout, that value changes. But, changing it manually has no effect. I have stepped thru the load bar layout code and see that toolbar info being seeded with it and even a SetWindowPos call being made with the point (and I see the xPos I set in the registry is used in that call). But when the bar displays, it stays where I last put it.

So it seems the reg entry isn't really used. Except that if I delete the entire hive for that bar ("Application-Bar1" for my bar), it goes back to the default pos at the left of the dockbar/app frame. But, just delete the xPos and yPos instead and CJ still places it as the position I moved it to before saving the bar layout.

Anyone have a suggestion of either how to influence the initial position (xPos is what I care about) or just where CJ is really getting the position from?

Hi dbrookes. With all the CJ stuff, I didn't even think about the MFC style docking calls.

CJ uses the ScreenToClient API when docking so I used your code with a bit of modification. I got the client rect of the app and called ClientToScreen on it. I also then added the .left member of the result to the left and right calculations.
