Error in using the GetCurrentConsoleFontEx

[Nisheeth]

I was trying to use the GetCurrentConsoleFontEx & the SetCurrentConsoleFontEx functions.
This is my code:

HANDLE hStdin = GetStdHandle(STD_INPUT_HANDLE); 
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);

CONSOLE_FONT_INFOEX orig, current;

current.cbSize = 16;

COORD FontSize;
	
FontSize.X = 10;
FontSize.Y = 10;

current.dwFontSize = FontSize;
current.FontWeight = 600;
current.FontFamily = FF_ROMAN;

	
if (GetCurrentConsoleFontEx(hStdin,FALSE,&orig))
	cout << "Got\n";
else
	cout << GetLastError();

if (SetCurrentConsoleFontEx(hStdout,FALSE,&current))
	cout << "\nSet";
else
	cout << endl << GetLastError();

Now when I run the program, I get the output as 87 for borh the conditions.
I checked the Error it signified, and found that it was for Incorrect Parameters.

But I can't understand how they could be wrong.
Any help??

EDIT:
I have tried using both hStdout and hStdin for the first parameter of the two Functions.

EDIT 2:
Got the problem.
The error was that I hadn't declared cbSize of orig and current

Though I have a new problem.
The program isn't effecting the Font of the console at all!
(BTW I am using Windows 7 ).

[andywestken]

current.cbSize = 16;

Where does 16 come from?

This line should read

current.cbSize = sizeof(CONSOLE_FONT_INFOEX);

P.S. sizeof(CONSOLE_FONT_INFOEX) == 84

@andywestken:
I had initially thought that it was the size of the characters (similar to font size, I mean).
I later saw a comment on the MSDN documentation saying that it has to be initialized as you specified.

That removed the errors the functions were giving.

I was now having another problem that the functions were returning TRUE, but no change was coming on the Text in the console.

Any help with that?

Please note that writing 84 in that code is a very bad idea, as it only has that value in win32, not in win64 or IA-64 architecture. Using sizeof operator is right thing to do.

I tried the values you used -- {10, 10}, 600, FF_ROMAN -- and it silently failed for me, too. But I got other value to work ok (see below)

SetCurrentConsoleFontEx's habit of silently failing does seem to be a common complaint about this function. And even worse, there is no official way (i.e. in MSDN) to get the list of supported fonts. But there are unsupported API calls: GetConsoleFontInfo and GetNumberOfConsoleFonts [1]

Note hat your posted code :
- is not initializing unused struct members to zero
- is not defining the font index or face name
- is using hStdin for the get call: both should use hStdOut

I got SetCurrentConsoleFontEx to work with

COORD FontSize = {16, 12};

CONSOLE_FONT_INFOEX current = {0}; // zero all members

current.cbSize = sizeof(CONSOLE_FONT_INFOEX);
current.nFont = 11; // apparently this is Lucida Console (no consts are provided [3])
current.dwFontSize = FontSize;
current.FontWeight = FW_NORMAL; // = 400, but should use predefined consts
current.FontFamily = FF_DONTCARE; // FF_ROMAN didn't work for me
// FaceName is unused 

If you just want to update the font size, you could reuse the info, just altering the size between the get and set calls (to hStdOut)

Thanks a lot.
I had corrected the last problem in my code already (After I corrected the cbSize problem,it Gave me the INVALID HANDLE error).
