I need to call the function CreateFontIndirect. I have made my header like
this:

private class LOGFONT
{
private int lfHeight;
private int lfWidth;
private int lfEscapement;
private int lfOrientation;
private int lfWeight;
private byte lfItalic;
private byte lfUnderline;
private byte lfStrikeOut;
private byte lfCharSet;
private byte lfOutPrecision;
private byte lfClipPrecision;
private byte lfQuality;
private byte lfPitchAndFamily;
private char[] lfFaceName;
}

[DllImport("coredll.dll")]
private static extern IntPtr CreateFontIndirect(ref LOGFONT lplf);

But when I call the function like this:

LOGFONT lf = new LOGFONT;
... // Setting lf
hfont = CreateFontIndirect(ref lf);

I get a NotSupportedExeption. How should I do it?
 
The problem is with .NETCF v1.0 you can't marshal an array with a nested
character array. The workaround is to store your logfont as a single byte
array and then use the BitConverter to get and set individual members within
the structure. For examples of this technique have a browse through the
OpenNETCF source in the vault - http://vault.netcf.tv (username guest,
password guest).

Thanks, but where in this vault should I look?

The OpenNETCF.Drawing.FontEx class comes to mind....
