parameter of the message in the SDK. A class derived from CCmdTarget can receive such a message, and its WPARAM records which menu item the message came from.3. control messages : Messages generated by the control, such as the click of a button, the selection of a list box, and so on, produce such messages in order to notify their parent window (usually a dialog box) of the occurrence of the event. This type of message is also presented in wm_command form. Classes derived from CCmdTarget can re

produces a hyperlink that has a URL pointing, and the LinkButton control belongs to the Button class control. It itself supports event handling, and there is no NavigateUrl property, its URL link function is mainly handled by the event processing--linkbutton control support onclick, OnCommand and other server-side methods. Can be summarized as follows:
LinkButton has the same appearance and style as hyperlink, but it has two other benefits, namely:
second, resulting in unsuccessful first request, and then will be sent again, so the most easy to think of is to ignore the first request, the following is the first solution.There are currently two solutions that are imperfect, and the first is to add the following statement to the Rowcommand event:if (request["x"] = = null request["y"] = = null)Response.End ();This statement, which determines the coordinates of the picture, if its coordinates are NULL, is the first request because the first
However, in the current example, the class Ctview of the current object does not overwrite the function, so the CWnd WindowProc is invoked.
This function gives the next work to the ONWNDMSG function to handle. If the onwndmsg is not processed, it is handed over to defwindowproc for processing.
Both Onwndmsg and DefWindowProc are virtual functions of the CWnd class.
Onwndmsg's prototype is as follows:
BOOL cwnd::onwndmsg (UINT message,
WPARAM WPARAM, LPARAM lparam,result*presult);
