Making a cross hair wid C++ TUT

[Ma44hew]

With this code you can draw anything on your screen. In the example below a red crosshair is drawn in the centre of the screen. To turn it on or off press F10. To close it turn the crosshair off and press F11+F12.

code:
#include <windows.h>
bool stdcross=false;
bool on=true;
void crosshair();
void crosshair2();
void crosshair3();
void crosshair4();
int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd )
{
HANDLE cross1, cross2, cross3, cross4; //multithreading
DWORD ThreadID; //get thread id

cross1 = CreateThread(NULL, //thread name
0,
(LPTHREAD_START_ROUTINE)
crosshair, //void name
NULL,
NULL,
&ThreadID);

cross2 = CreateThread(NULL,
0,
(LPTHREAD_START_ROUTINE)
crosshair2,
NULL,
NULL,
&ThreadID);

cross3 = CreateThread(NULL,
0,
(LPTHREAD_START_ROUTINE)
crosshair3,
NULL,
NULL,
&ThreadID);

cross4 = CreateThread(NULL,
0,
(LPTHREAD_START_ROUTINE)
crosshair4,
NULL,
NULL,
&ThreadID);

while(on){
Sleep(1);
if(GetAsyncKeyState(VK_F10)& (1==1)){
stdcross=!stdcross;
}
if(GetAsyncKeyState(VK_F11)& GetAsyncKeyState(VK_F12)){
on=false;
}
}
}

void crosshair(){
while(on){
Sleep(1);
if(stdcross){
int cx = GetSystemMetrics(SM_CXSCREEN); //resolution
int cy = GetSystemMetrics(SM_CYSCREEN);
int pos1=cx/2; //centre points
int pos2=cy/2;
HDC hwnd = GetDC(0); //needed to draw
while(stdcross && on){
Sleep(1);
for(int xhair1=5;xhair1<10;xhair1++) //draw a line 5 pixels long{
SetPixel(hwnd,pos1+xhair1,pos2,RGB(0,255,0)); //set each pixel
}
}
}
}
}

void crosshair2(){
while(on){
Sleep(1);
if(stdcross){
int cx = GetSystemMetrics(SM_CXSCREEN);
int cy = GetSystemMetrics(SM_CYSCREEN);
int pos1=cx/2;
int pos2=cy/2;
HDC hwnd = GetDC(0);
while(stdcross && on){
Sleep(1);
for(int xhair1=5;xhair1<10;xhair1++){
SetPixel(hwnd,pos1-xhair1,pos2,RGB(0,255,0));
}
}
}
}
}

void crosshair3(){
while(on){
Sleep(1);
if(stdcross){
int cx = GetSystemMetrics(SM_CXSCREEN);
int cy = GetSystemMetrics(SM_CYSCREEN);
int pos1=cx/2;
int pos2=cy/2;
HDC hwnd = GetDC(0);
while(stdcross && on){
Sleep(1);
for(int xhair1=5;xhair1<10;xhair1++){
SetPixel(hwnd,pos1,pos2+xhair1,RGB(0,255,0));
}
}
}
}
}

void crosshair4(){
while(on){
Sleep(1);
if(stdcross){
int cx = GetSystemMetrics(SM_CXSCREEN);
int cy = GetSystemMetrics(SM_CYSCREEN);
int pos1=cx/2;
int pos2=cy/2;
HDC hwnd = GetDC(0);
while(stdcross && on){
Sleep(1);
for(int xhair1=5;xhair1<10;xhair1++){
SetPixel(hwnd,pos1,pos2-xhair1,RGB(0,255,0));
}
}
}
}
}

Sorry for not participating in the act, but is this the finished code?

where to set the code?

what to do with it?

[nebez1]

What do you think? You're supposed to compile it, durr.

Oh, and I haven't tested this myself so I don't even know if it works, but nice.
And you might want to replace TUT with CODE, because this isn't a tutorial, you just plain-out pasted the script.

[Ma44hew]

Yes it is the full code.
