Well, I keep getting “There was a problem reading the length of the name”.
I will have to dig into that when I have a clear mind.
Hmm I tested it with https://github.com/google/fonts/raw/master/ofl/alexbrush/AlexBrush-Regular.ttf and it worked fine.
You might have it pointing to a font that it cant read 
I better make sure it can read any font that is recognized by Windows.
[quote=311113:@Cho Sing Kum]I have reference to this old solid workhorse code. I tested it after making sure that TTFontFile is assigned a valid filename in Command1_Click event.
I converted it to Xojo but no luck. It seems the function has become inoperative in Windows 10. No error, but the function returns systematically zero.

Well, something else is happening. Pointing to that font triggers the same error 
Hmm, thats odd, it works a treat here, did you use the same code just cut and paste from my post?
Did you call it with an absolute path, ie.
system.DebugLog GetFontName("C:\\Test\\AlexBrush-Regular.ttf")What version/edition of windows are you running, w10/64 ? w10/32 ?
Can you try it in a brand new blank project so you know the project settings are all default?
If you double click that font in windows, does it show ok ? ie. is the download not corrupt
Does the exe have read permission to the location of the font?

I did copy from the forum.
I am under Windows 10, and the font is not in a restricted folder.
Could you consider posting your project ?
Ummm I tried making a copy of the font into the same folder and loading that, now I’m having the same problem as you, give me a couple of mins to figure this out.
Sorry Michel, but I think this one had beaten me. I’m just getting strange problems, if I change filename or folder the routine just stops working. I guess thats why its an undocumented call. I have double and triple checked my calls and I cant see where it might be causing a problem. All I am changing is the length of a WString being passed to the function, heck if I keep the length the same and just change a character from r to s it stops working boggle
I have also tested it in another language and I see the same problems, so I dont think its a Xojo issue.

I hope that someone else with a bit more windows api knowledge might be able to shed some light on it.
It’s alright Julian. It is an undocumented call anyway. That probably explains a lot. Thank you for your efforts.
I will get back to my efforts to parse the font.
CreateScalableFontResourceA is available in Windows 10. I just ran the old code there and it works. I also used DLL Export Viewer to check exported functions.
Add:
Maybe this is the problem - It only works with True Type fonts.
