Cannot open Font .ttf with ShellExecuteW

New comment
 

Dear Coders,

I can open text files, videos, images,  but not Font files ".ttf ".  I would like to open it first, then install. Is there a trick to open them ?

Thank you in advance for your support,


#import "shell32.dll"
int ShellExecuteW(int hwnd, string lpOperation, string lpFile, string lpParameters,string lpDirectory, int nShowCmd);
#import

string FileName = "SPORT.ttf";

Mpower:   but not Font files ".ttf ".  I would like to open it first, then install. Is there a trick to open them ?
  1. You do not open them, you install it into Windows and then that font can be selected in text operations.
  2. Shell only can start executables - .exe .com.

Thank you William Roeder for your prompt reply  ;)

I continue to look for the way how to install Font programmatically with MT4. I mean open the window, then we just click on Install.

Have a great day,
