Problem with ComboBox child window

Hello,

I am developing a plugin for a third-party application, which is among other things adding the possibility to skin the application window.

I am able to use the ActiveX correctly (it skins the scrollbar of dropdown window of the ComboBox as expected), but the MFC version refuses to skin the scrollbar of the child window, keeping the current Windows skin. Normal child windows (like a MessageBox) are skinned correctly.

Here is an excerpt of the program, showing how I activate the SkinFramework.

union uMyUnion {     long unsigned uValue;     HWND hWnd; }; (...) if (XTPSkinManager()->LoadSkin(_T(szTheme), _T(szIniFile)) != TRUE) {     // failure, abort here     nLastError = 12001;     lua_pushnumber(L, (double)1); } else {     // apply skin     u.uValue = (long unsigned)dParameter;     XTPSkinManager()->SetApplyOptions(XTPSkinManager()->GetApplyOptions() | xtpSkinApplyFrame | xtpSkinApplyColors | xtpSkinApplyMetrics);     XTPSkinManager()->ApplyWindow(u.hWnd);     lua_pushnumber(L, (double)0); }

Here is a picture showing the result, note that the scrollbar is not correctly skinned:



Could somebody show me what I am missing? Thank you in advance.

Hello, thank you for your post.

I tried that in the past (and once more right now just to make sure), but it didn't seem to make any difference. A pop-up message box is skinned correctly, so it seems that I am indeed skinning child windows - just not that one.
The strange thing is that when I use the OCX and perform the same steps

SkinFramework:LoadSkin(".\\AutoPlay\\Docs\\VistaVGBlue.cjstyles",""); SkinFramework:ApplyWindow(Application.GetWndHandle());

it works normally, and the dropdown is skinned. It is as if the OCX is doing something undocumented, that has to be done as well to make the MFC version work in the same way.

Thank you!

Just calling LoadSkin once (without pointing to any skin) before the dialog is displayed is indeed sufficient - now the scrollbars of the combobox are skinned correctly.
