I have code to install fonts, but I don't want to be running that code every time the user starts the program...only when the font does not exist.  So how do I check to see if the font is already loaded on the user's machine?

    Shared Sub Main(ByVal args As String())
        ' Get the installed fonts collection.
        Dim installed_fonts As New InstalledFontCollection

        ' Get an array of the system's font familiies.
        Dim font_families() As FontFamily = installed_fonts.Families()

        ' Display the font families.
        For Each font_family As FontFamily In font_families
            Console.Write (font_family.Name & ", ")
        Next font_family
    End Sub
End Class

Open in new window


This is a way to get all the fonts installed on a system


Use something like this
InstalledFontCollection installedFontCollection = new InstalledFontCollection();

// Get the array of FontFamily objects.
FontFamily[] fontFamilies = installedFontCollection.Families;

Open in new window


Then compare the font you want to install with the array for a match
