, the Connection Manager queues the requested connection, then use CSPs to establish a connection at a suitable time. [API function ]: A) connmgrapireadyevent () functionFunction prototype: handle winapi connmgrapireadyevent ();Using this function, we can return a connection event handle. Remember to release it in time after obtaining the handle. B) connmgrconnectionstatus () functionFunction prototype: hresult winapi connmgrconnectionstatus (han

the ID to determine which method (or attribute) of the specified object to call. Therefore, the method used to call the object through the method (or attribute) name is, you must call the getidsofnames method of idispatch to convert the method (or attribute) name to an ID before calling the object method through the invoke method of idispatch. To facilitate operations, three functions are encapsulated to call the methods of the webbrowser object, read the attributes of the object, and set the a

method (or property) name to an ID before you can invoke the method of the object through the IDispatch invoke method. For ease of operation, three functions were encapsulated to invoke the WebBrowser object's method, read the object's properties, and set the object's properties. DispID Cwebbrowserbase::findid (IDispatch *pobj, Lpolestr pName) {DispID id = 0; if (FAILED (Pobj->getidsofnames (iid_null,pname,1,locale_system_default,id))) id =-1; return ID;}

follows: A) audio codecs and Renderer For example, to play music in MP3 format, you must check MP3 Codec. B) Video codecs and Renderer C) DirectShow This includes the Core Components and filters of DirectShow. DirectShow uses filters to complete core functions. If the DirectShow component is not added, use the SDK exported by the system. It is likely that our DirectShow application compilation will fail. Even if the compilation is successful, it cannot work normally. In addition, there are M

COM component function call (invoke of idispatch)Assume that there is a component whose progid is "atlfunc. mymath.1". The attributes and interface methods are as follows

Gifolecontrol can insert images, including BMP, JPG, and PNG. The image size is not limited. The key point is that GIF animation can be inserted in RichEdit. Currently, swf format cannot be inserted. At the same time, you can directly display tooltip In the inserted image and GIF to facilitate the application. The interface defined by gifolecontrol is as follows: Interface igifctrl: idispatch {[Propput, Bindable, requestedit, ID (dispid_bordercolor)]Hresul
