Question
In standard Pocket PC applications they have a special header in dialogs
with blue bold title. How can I insert this header in my dialog (property page)?

Pocket PC logo requirements states that application should always show application
name in the navigation bar. It is written:
Required: Application title displayed on NavBar. The topmost application must
continuously display its title on the NavBar, regardless of which view the application
is in. Other titles, such as the names of the current view, document, card, dialog,
etc must be within the client area if it is displayed.
Logo requirements do not describe how you should show your dialog title and there is no
API function for that. But many developers want to make a program that looks like a standard
one. Users know standard programs and they expect the same type of visualization of
dialog titles.
Here is code that shows such a title. You can use it in dialogs and in property pages.
Handle WM_PAINT message and add the following code in your OnPaint method.

dc.SelectObject(pSave);
// paint line
CPen blackPen(PS_SOLID, 1, RGB(0,0,0));
CPen *pOldPen = dc.SelectObject(&blackPen);
dc.MoveTo(0, nHeaderHeight);
dc.LineTo(nWidth, nHeaderHeight);
dc.SelectObject(pOldPen);

CPaintDC dc(this);
PaintHeader(dc, _T("Dialog title here"));
