Registers an application with SftTree/DLL.

C

BOOL WINAPI SftTree_RegisterApp(HINSTANCE hInst);

C++

static BOOL CSftTree::RegisterApp();

Parameters

hInst

The instance handle of the application, which will use SftTree/DLL controls.

Returns

The return value is TRUE if SftTree/DLL has been initialized for this application, otherwise FALSE is returned.

Comments

The RegisterApp function registers an application with SftTree/DLL.

This call allows SftTree/DLL to register all required window classes for the calling application.  This call has to be made before any SftTree/DLL controls are created.

If an application has multiple threads which create controls, each thread must also call RegisterApp to initialize support for SftTree/DLL.  If only the main thread of a process creates controls (even if other threads communicate with the control), no additional calls to RegisterApp are required.  

An application should call UnregisterApp once the application no longer uses SftTree/DLL controls.  In addition, each thread that called RegisterApp during initialization must call UnregisterApp before the thread terminates.
