I have a CXTTabCtrl with two CPropertyPage items. The problem is that the background of the property page is painted in gray, where a white color is expected:
 
 
Ok, so let's enable transparency in dialog template. That should do it!
 
 
It turns out that this causes many problems. First of all the controls disappear when moving the mouse (see above). Secondly, sometimes the application hangs completely and its window cannot be seen when pressing Alt+Tab. "Did I do that?"
 
I also tried the previously mentioned hack where this call was made in CMyPropertyPage::OnInitDialog:

XTPSkinManager()->EnableThemeDialogTexture(m_hWnd, ETDT_DISABLE);

... but it did not help . Any ideas? Thanks!

Don't set transparent flag and call

XTPSkinManager()->EnableThemeDialogTexture(m_hWnd, ETDT_ENBLED); for both pages.

Hi,
 
I've tried both ETDT_DISABLE and ETDT_ENABLE and I can't get rid of the gray background. This is what I do:
 
// CMyDialog::OnInitDialog
m_pageOne.Create(CPageOne::IDD, &m_tabCtrl);
m_pageTwo.Create(CPageTwo::IDD, &m_tabCtrl);
 
m_tabCtrl.ModifyStyle(0, WS_CLIPCHILDREN | WS_CLIPSIBLINGS);
m_tabCtrl.AddControl(_T("One"), &m_pageOne);
m_tabCtrl.AddControl(_T("Two"), &m_pageTwo);
m_tabCtrl.SetCurFocus(0);
 
Then in OnInitDialog of CPageOne/CPageTwo:
XTPSkinManager()->EnableThemeDialogTexture(m_hWnd, ETDT_ENABLE);

I made a sample to make it easier to track the problem.

Lol... the flag should be ETDT_ENABLETAB.
 
Thanks for the hint.
