fonts appearing differently on different machine

i have 2 issues with fonts..

- on my computer, the text are all ok but on another computer.. there are some characters that are replaced by symbols... like the ("\" replaced by a currency symbol)

- on my computer, the text size is ok ,on another computer, the text are larger and doesn't even fit in a command button.... (probably system font size or resolution-related)..

my question
any solution? lol

Sounds as if you're using a font that's not installed on the other computer (or not installed on your computer). If a font isn't installed, Windows will use another font in that font family.

Resolution: Install the missing font on the computer that's missing it.

how can i detect if font is missing on the other computer in my application??

All fonts are installed in %windir%\fonts, or C:\Windows\Fonts.

I think there is an API to get that specific folder. If not, you can use the GetWindowsDirectory() API function and then append \fonts to it.

Then you can check if the file exists.

Alternatively, you can check them like this:

VB Code:

Private Function FontExists(ByVal FontName As String) As Boolean
    Dim strCName As String, intLoop As Integer
    
    strCName = LCase$(FontName)
    
    For intLoop = 0 To Screen.FontCount - 1
        
        If LCase$(Screen.Fonts(intLoop)) = strCName Then
            FontExists = True
            Exit For
        End If
    
    Next intLoop
    
End Function
 
Private Sub Form_Load()
    'Test function.
    MsgBox FontExists("tahoma"), , "TRUE"
    MsgBox FontExists("fjlskdfj"), , "FALSE"
End Sub

thanks how can i set a font to all the textboxes/listboxes in my app???
