I have integrated skins into our application and see the various effects the skins I load have on the app, its windows and controls. But I have some windows that when we display them lock up our app. Spy++ shows me a constant stream of WM_PAINT and painting related Windows messages are being sent to the window.
This is on a per window basis. I took one of our floating windows that has this problem and called the Windows API SetWindowTheme(hWnd, "", ""); to turn off themes for the window. I have used that when MS themes have caused problems in the past hoping that this call will disable whatever Codejock is doing. It made no difference. If I display the window, it still goes crazy with a constant stream of display related messages as seen using Spy++.
This is in CodeJock 16.2.

We pulled 16.3 and I still see this issue. Now it appears to be a constant stream of WM_UPDATEUISTATE calls to each of the buttons on the window that "locks" us up.

mcmastl,
I'm sorry but I solved this issue already and failed to post. At one point I had issues with a focus rect on buttons being drawn. I found a work-around for that by calling SendMessage( WM_UPDATEUISTATE, MAKEWPARAM(UIS_CLEAR, UISF_HIDEFOCUS), 0 ) to our dialogs that were affected. That fixed the focus rect issue. And it caused the problem with the theme. The focus rect issue was quite old and I removed my send message code and that fixed the problem with the theme. I tested and didn't see the focus rect issue come back. So basically, I caused the constant display issue as each time the ui state changed, the background was erased and that caused the cycling.
When I added the update ui state code, I did find that I could get a draw message right away so I had a flag I set so that if a background erase came around again, I didn't send the message again. With the theme code, the redraw happened after I sent the WM_UPDATEUISTATE message and returned from the OnEraseBkgnd call.
Bottom line, this is not an issue anymore.
