COleObjectFactory::UpdateRegistry

  • 项目

voidUpdateRegistry(LPCTSTRlpszProgID**=NULL);**

virtualvoidUpdateRegistry(BOOLbRegister**)=0;**

Parameters

lpszProgID

Pointer to a string containing the human-readable program identifier, such as “Excel.Document.5.”

bRegister

Determines whether the control class’s object factory is to be registered.

Remarks

Brief discussions of the two forms for this function follow:

  • UpdateRegistry( lpszProgID )   Registers this object factory with the OLE system registry. This function is usually called by CWinApp::InitInstance when the application is launched.

  • UpdateRegistry( bRegister )   This form of the function is overridable. If bRegister is TRUE, this function registers the control class with the system registry. Otherwise, it unregisters the class.

    If you use MFC ActiveX ControlWizard to create your project, ControlWizard supplies an override to this pure virtual function.
