L_UseContainerControl (original) (raw)

Summary

Dynamically loads the DLL that provides support for the LTCONTAINERCLASS registered class.

Syntax

#include "ltivw.h"

L_LTIVW_API L_VOID L_UseContainerControl(L_VOID)

Parameters

HDISPCONTAINER hCon

Handle to the container

Returns

None.

Comments

The LTCONTAINERCLASS registered class uses messages rather than function calls. Therefore, the required dynamic link library (LTIVW15u.dll) is not loaded automatically. Therefore, the toolkit provides this dummy function in the DLL, which you can call before using the registered class messages.
