Dear Sir/Madam,



We have a Visual C++ 6.0 Mfc project with Prof-UIS.

When we run application we can change current GUI Theme over Theme Switcher Toolbar

But I can’t realize the event of changing themes in the code. How can I do this?
How can I use OnThemeChanged method?
Hope to hear back from you as soon as possible.



Best regards.

Dear Sir\Madam,

When we run our visual C++ 6.0 Mfc application ,At first, we can see all of the Theme (it must be thirteen) on the Theme Switcher Toolbar.But now there are only eight Theme on it.How did the other Theme leave?

There is a CExtThemeSwitcherToolControlBar ::m_bEnableOffice2007r3 property, which when set to true, adds three additional themes. But these themes are relevant to the ribbon control only. So if you have no ribbon bar, there is no point to turn this option on.

We have just added a FAQ that should answer your question:

How to catch the event when the current theme has changed?

Make a theme switcher toolbar class derived from CExtThemeSwitcherToolControlBar and override the following method in it:    virtual void ThemeSwitcher_OnButtonInvoke(
        CExtThemeSwitcherToolButton * pTBB
        );
In it you should call base class method first and then you can do whatever code you need. E.g.:

void CMyThemeSwitcherToolControlBar::ThemeSwitcher_OnButtonInvoke(
	CExtThemeSwitcherToolButton * pTBB
	)
{
	CExtThemeSwitcherToolControlBar::ThemeSwitcher_OnButtonInvoke(pTBB);
CRuntimeClass * pRTC = NULL;
	if( ! m_mapCmd2RTC.Lookup( pTBB->GetCmdID(false), pRTC ) )
		return;
	if ( pRTC == RUNTIME_CLASS( CExtPaintManagerStudio2005 ) ) {
		// do something here
	}
}

The only problem is, this method is called also when the currently selected theme’s button is clicked in the toolbar. Check out base class implementation in ProfUIS source to see how they check for this.
