C++ - two times DrawText()

Question

I'm currently experiencing an error with my program.
My program has two rectangles, each of them surrounded by a groupbox.
Currently I'm trying two place text in each of them.
I've already got text in the first rectangle - fine (with DrawText()).
If I'm trying to display text in the second rectangle (also with DrawText()), the text is not displaying.
Here's the code I'm using:

hdc = BeginPaint(hwnd, &ps);
SelectObject(hdc, font);
DrawText(hdc, lpcwstr, wcslen(lpcwstr), &rect, DT_LEFT);
DrawText(hdc, lpcwstr, wcslen(lpcwstr), &rect_2, DT_LEFT);
EndPaint(FindWindow(NULL, L"Statistik (seit dem 01.01.2015)"), &ps);

Unfortunately I have no idea why the text is not displaying as expected.
Does anybody of you have a suggestion why this doesn't work?

Check your error returns. Also why are you calling `FindWindow()` in your `EndPaint()`? That's not guaranteed to return the same window you're thinking of (if any window)... and you know the `hwnd` you passed to `BeginPaint()`; just use it. — andlabs, Jan 17 '15 at 16:29

[SOLUTION]
I was able to figure out what the problem was.
Not visible in the snippet, I posted initially, but the coordinates I set for the rectangles, were wrong.
Sadly I were not aware that all values are coordinates.

The only difference between the two calls is the RECT that you pass. The obvious conclusion is that you initialised one of the rectangles incorrectly.

You should restore the original font before calling EndPaint. And the call to FindWindow should be removed. Pass hwnd. Finally, your code performs no error checking at all. That's always imprudent.
