Title: Win32 - How to draw a WCHAR (Unicode Char) with TextOut() ?
Post by: va!n on June 07, 2012

For my Win32 project i want like to draw special chars with something like TextOut()... I will define the special chars as WCHAR and set its HexValue like following codesnip but i cant get it work. Any idea how to solve this? Thanks!

Code: [Select]

WCHAR testchar = 0x00A9;

TextOut( hdc, 20, 10, TEXT("A"), 1);        // Works fine !
TextOut( hdc, 80, 10, (WCHAR)testchar , 2);   // Does not work :(

Btw yes, the project is compiled by using unicode charset!

WCHAR tc[2]={0};
tc[0]=testchar;
TextOut(,,,tc,2);

TextOut prints strings not characters so you need to make a string.

if TextOut doesn't need a NULL terminator you could just do..

WCHAR testchar = 0x00A9;

TextOut( hdc, 20, 10, &testchar, 1);

@Canopy:
Thanks! I am not sure if TextOut() requires a NULL terminated string or not...
However, it seems to work ;) K++
