I am trying to use GetThemeFont to read the font data from a visual style, but I can’t seem to get it to return anything. Here is how I’m using it:
IntPtr h = OpenThemeData(this.Handle, 'Button'); LOGFONT font = new LOGFONT(); int r = GetThemeFont(h, IntPtr.Zero, 1, 1, 210, out font); CloseThemeData(h); The return value is always ‘-2147023728’ and font is always null. The place where I put 210 (for TMT_FONT), I’m not really sure what to use there. Any help on this would be much appreciated.
-2147023728 is the decimal equivalent of 0x80070490L, which is the value assigned to
E_PROP_ID_UNSUPPORTED. From the ‘Remarks’ section of the documentation of of GetThemeFont:The property is not supported for the part and state combination that you are passing in.
