Installing a font in .NET

2 posts in this topic

Specifically, VB.NET I want to install a font using VB.NET. I'm not talking about the private install, but rather, installing a font on the system. After some extensive research on this, I can't find a way to do it. It seems, according to the MSDN help, that you need to use AddFontResource, which is part of the GDI. However, I have yet to find how to import GDI functions into .NET applications. Many thanks to anyone who can help.

Try putting the following in one of your classes:
public static extern int AddFontResource(string lpszFilename);
I like to make a Gdi32 class and put all of my GDI calls in there:
public class Gdi32
public static extern int AddFontResource(string lpszFilename);

Thanks for sending me down the right track, Rob. In VB, the formatting is a little different, but I figured it out.

Also, for reference, here's how to install a font from a ttf file in VB.net

Before your class declaration, you need to put:
<Assembly: RegistryPermissionAttribute( _
SecurityAction.RequestMinimum, All:="HKEY_LOCAL_MACHINE")>

Then, inside the class, import some API functions:
Private Const WM_FONTCHANGE As Long = &H1D

<DllImport("gdi32.dll")> _
Public Shared Function AddFontResource(ByVal lpszFilename As String) As Integer
End Function

<DllImport("user32.dll")> _
Public Shared Function SendMessage(ByVal hWnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
End Function

Then, is the actual installation. I put it in a button press.

'let's assume that filePath is a string with the full path of the ttf file
Private Sub cmdAddFont_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddFont.Click
Dim regKey As RegistryKey = Registry.LocalMachine.OpenSubKey("Software", True).OpenSubKey("Microsoft", True).OpenSubKey("Windows NT", True).OpenSubKey("CurrentVersion", True).OpenSubKey("Fonts", True)
Dim fileName As String
Dim tempFonts As New PrivateFontCollection
Dim fontName As String

fileName = GetFileName(filePath)
fontName = tempFonts.Families(0).Name

If Not System.IO.File.Exists(FONTS_FOLDER & fileName) Then
'copy the font into the windows font directory
System.IO.File.Copy(filePath, FONTS_FOLDER & fileName)
'add it to the system font table
AddFontResource(FONTS_FOLDER & fileName)
'write the change in the registry
regKey.SetValue(fontName, fileName)
'alert all top-level programs about the change
End If

End Sub

Private Function GetFileName(ByRef fullPath As String) As String
Return fullPath.Substring(fullPath.LastIndexOf("\") + 1)
End Function

Private Function GetFontName(ByRef fileName As String)
Return fileName.Substring(0, fileName.IndexOf("."))
End Function

Note: this only works on NT machines (this includes XP). To make it work on machines before then, change "Windows NT" in the registry key to just "Windows"

Also, for some reason, I cannot get the newly installed font to show up on an InstalledFontsCollection until I restart the program. I'm working on that one. Post here if you have any ideas.

Hope this was helpful.
