Jazyk C - zmena fontu v console application

However, this API is not available to pre-Vista operating systems. I
understand that you do not prefer the ways just for Vista. Although the
pre-Vista OS's do not have the similar documented APIs, there are a couple
of ways to set the font prior to loading the console app:

CONSOLE: howto change console font programmatically

The second method mentioned by this article is to set the console properties
(including font) for the specified console application. For example, if the
title of the console app at run time is "D:\Test\TestConsole.exe", we can
create a key named 'D:_Test_TestConsole.exe' under HKCU\Console, and have a
"FaceName" string value equaling "Lucida Console". Please also note that if
the console app will not run as the current user (HKCU), you would need to
add the key to the corresponding session ID under HKEY_USERS.

The third method mentioned by the above article is to create a shortcut to
the console app, and specify the font in the shortcut's properties. This
solutions works well in Windows shell, but I'm not sure that it also works
for the stdio redirection. It deserves a test. Shortcuts don't change the
font of an existing console. They provide the initial console settings. And
they don't do it by calling any API. The console subsystem parse shortcut
files directly. By the way, when we have a shortcut and set the font
property, a registry key with the same name of the shortcut file will be
added to HKCU\Console, similar to the second method.

Please have a try and let me know whether the above solutions are helpful to
you or not. I will do my best to help you.
