This function creates a logical font that has the characteristics defined in the specified structure. An application can subsequently select the font as the current font for any device context.


HFONT CreateFontIndirect(
  const LOGFONT* lplf
); 

lplf

[in] Long pointer to a LOGFONT structure that defines the characteristics of the logical font.

A handle to a logical font indicates success. NULL indicates failure. To get extended error information, call GetLastError.

The CreateFontIndirect function creates a logical font with the characteristics specified in the LOGFONT structure. When you select this font by using the SelectObject function, the font mapper for the graphics device interface (GDI) attempts to match the logical font with an existing physical font. If the font mapper fails to find an exact match, the font mapper provides an alternative that has characteristics that match as many of the requested characteristics as possible.

When you no longer need the font, call the DeleteObject function to delete the font.

Windows CE 2.0 and later support either TrueType or raster fonts, but not both. The OEM chooses the font type, raster or TrueType, at system design time, and an application cannot change the font type.

Windows CE 1.0 and 1.01 support only raster fonts.

Aa911457.Caution(en-us,MSDN.10).gifCaution:
The internal leading height of the Meiryo font is greater than for other fonts. This can cause problems unless proper care is taken in programming and testing. A good approach is to use a negative value of lfheight in the LOGFONT structure. See that topic for more information. Use of the Meiryo font should be thoroughly tested.

The following code sample shows how to use the CreateFontIndirect function with the characteristics specified in the LOGFONT structure.

To make the following code example easier to read, error checking is not included. This code example should not be used in a release configuration unless it has been modified to include secure error handling.
