AddFontFile XP C＃

Question

I have a project where I need to load a Postscript font from disk. I found I could use "AddFontFile". Doing some research I see that I have to pipe the two fonts http://msdn.microsoft.com/en-us/library/system.drawing.text.privatefontcollection.addfontfile.aspx together so I tried:

fontCollection = new PrivateFontCollection();
fontCollection.AddFontFile(@"C:\Temp\Font\myfont.PFM|C:\Temp\Font\myfont.PFB");

I'm getting aa error "Illegal characters in path". I'm not sure if I'm piping the two fonts correctly.

Any help would be great, I should mention we are still on XP not sure if that makes a differnts or not.

Answer 1

You cannot have the pipe | character in your filename. PrivateFontCollection.AddFontFile requires a valid filepath. Hence your "Illegal characters in path" exception. The input at MSDN is A String that contains the file name of the font to add. Try passing a single file at a time - I don't know about this piping idea..

As for your Postscript desire, the Remarks section states that OpenTypes have limited support.

Answer 2

After some searching I got it to work and I'd like to share on how I solved the this: AddFontFile was the wrong API i Needed to use AddFontResource instead

            String fontPath = @"C:\Temp\Font2\GXSTRA03.PFM|C:\Temp\Font2\GXSTRA03.PFB";
            int result = AddFontResource(fontPath);
            long msg = SendMessage(HWND_BROADCAST, WM_FONTCHANGE, IntPtr.Zero, IntPtr.Zero);

to remove the font resource

RemoveFontResource(@"C:\Temp\Font2\GXSTRA03.PFM|C:\Temp\Font2\GXSTRA03.PFB");
long msg = SendMessage(HWND_BROADCAST, WM_FONTCHANGE, IntPtr.Zero, IntPtr.Zero);

If anyone is new on making a external WinApi call here is the import and import DLL code that I used

using System.Runtime.InteropServices;

private static uint WM_FONTCHANGE = 0x1D;

        Import("gdi32.dll")]
        static extern int AddFontResource(string lpFilename);

        [DllImport("gdi32.dll")]
        static extern bool RemoveFontResource(string lpFileName);

        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        private static extern int SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

This fonts now shows in word and notepad ect..
