Do not be confused, the military is bullets and bombs. A military action is not a Toys For Tots fund raising..The primary, and for some the sole MOS is rifleman. This means clean it to kill em. Combat ready, and combat proficient don’t mean traffic control.

There has never been a photographer who hasn’t asked or been asked:

So what camera do you use, and what kind of lens?

Yet there’s never been a sculptor asked:

So what chisel do your use, and what kind of hammer?

This is the first and obvious difference. As a principal it means that often what we know first is the major parameter that distinguishes one from another. Often, but not always. That what you know about a company is what you first know about them.

ATL controls are created by default with the CS_HREDRAW and CS_VREDRAW class styles. These styles cause the entire window to be redrawn when the window is resized.
Remove the CS_HREDRAW and CS_VREDRAW styles from the window by overriding the GetWndClassInfo() function. Add the following function to your CComControl-derived class:

static CWndClassInfo& GetWndClassInfo()
{
static CWndClassInfo wc = {{ sizeof(WNDCLASSEX), 0, StartWindowProc,
0, 0, 0, 0, 0, (HBRUSH)(COLOR_WINDOW+1), 0, “MyControlClass”, 0 },
NULL, NULL, IDC_ARROW, TRUE, 0, _T(“”)};
return wc;
}
