InitCommonControlsEx function (commctrl.h)

Ensures that the common control DLL (Comctl32.dll) is loaded, and registers specific common control classes from the DLL. An application must call this function before creating a common control.

Syntax

BOOL InitCommonControlsEx(
  [in] const INITCOMMONCONTROLSEX *picce
);

Parameters

[in] picce

Type: const LPINITCOMMONCONTROLSEX

A pointer to an INITCOMMONCONTROLSEX structure that contains information specifying which control classes will be registered.

Return value

Type: BOOL

Returns TRUE if successful, or FALSE otherwise.

Remarks

The effect of each call to InitCommonControlsEx is cumulative. For example, if InitCommonControlsEx is called with the ICC_UPDOWN_CLASS flag, then is later called with the ICC_HOTKEY_CLASS flag, the result is that both the up-down and hot key common control classes are registered and available to the application.
