Code:

#include <windows.h>
#include <stdio.h>

int main( void )
{
HDC hDC = GetDC(NULL);
for(;;)
{
   if(!ArcTo(hDC, 20, 20, 50, 60, 50, 60, 20, 60))
      printf("failed\n");
   TextOut(hDC, 500, 500, TEXT("Wat"), strlen("wat"));
}
}

TextOut works, but ArcTo doesn't. It isn't returning false either Neutral

ArcTo() requires a form window, not a console. It's returning true because it's being drawn, but you can't see it because you don't have a form.

So, say I have notepad, can I draw it on Notepad? Also is there a way to make the lines a different color and make it a little bolder?

@op: you just didn't set your pen type. Create a pen, set it to a color you can actually see against the black console, then select it into your device context.

Code:

#include <windows.h>

int main(void)
{
HWND hwnd = FindWindow("ConsoleWindowClass", NULL);
HPEN hp    = CreatePen(PS_SOLID, 1, RGB(255, 255, 255));
HDC hdc    = GetDC(hwnd);
HGDIOBJ hpOld = SelectObject(hdc, hp);

while(!GetAsyncKeyState(VK_ESCAPE))
{
   ArcTo(hdc, 50, 50, 100, 100, 50, 50, 100, 100);
   TextOut(hdc, 100, 100, "slovach", 7);
}

SelectObject(hdc, hpOld);
DeleteObject(hp);
ReleaseDC(hwnd, hdc);

return 0;
}
