so i've got this code that pkedpker posted (thanks)
| Code: | void DrawMyText(char *windowcaption, float x, float y, char *mybuffer, int howmany)
{
gamewindowhandle = FindWindow(NULL, windowcaption); //get the game hwnd
HDC hdc = GetDC(gamewindowhandle);
SetBkColor(hdc,RGB(255,255,255)); //WHITE BACKGROUND
SetBkMode(hdc, TRANSPARENT); //MAKES BACKGROUND TRANSPARENT
//SO ALL YOU SEE IS THE TEXT
//MAKE SHADOW FOR TEXT (BLACK) and offset it by 1 pixel
SetTextColor(hdc,RGB(0,0,0));
TextOut(hdc,x+1,y+1, mybuffer,howmany);
//MAKE SECOND SHADOW FOR TEXT (BLACK) and offset it by 2 pixels
TextOut(hdc,x+2,y+2, mybuffer,howmany);
//PRINTS MY TEXT OVER THE BLACK TEXT IN RED, GIVES IT A DROP SHADOW APPEARANCE.
SetTextColor(hdc,RGB(255,0,0));
TextOut(hdc,x,y, mybuffer,howmany);
UpdateWindow(gamewindowhandle);
ReleaseDC(gamewindowhandle,hdc);
} |
but i've got errors, i know i can just use L"my string" for strings i set, but how could i do the equivalent to a variable, because adding the L just changes the name
i've tried doing this:
gamewindowhandle = FindWindow(NULL, (LPCWSTR)windowcaption); to make it a wide string, should this work properly?

Just use the TEXT or _T macro.
#include "tchar.h"
FindWindow(NULL, _T("QUAKE3"));
and GDI is pretty flickery ingame. |

i need to use a variable though, so:
char *windowcaption
gamewindowhandle = FindWindow(NULL, windowcaption);
but _T just changes it to Lwindowcaption, which isn't declared, how do i do it with a variable?

why do you need to?
anyway, TCHAR + _T |

HWND target = NULL;
TCHAR *window = _T("icculus.org/quake3");
target = FindWindow(NULL, window); |
