web|window| program once when I was doing a project, I suddenly found an interesting call, in a. NET Web program, you can use the System pop-up box in the window package,
The runtime can be a pop-up balloon on the server, if the server clicked on the pop-up button, the client IE can continue to run, otherwise it looks like the server's code has an infinite loop, always running the same.
Examples are as follows:
if (MessageBox.Show) (ok to delete?) "," prompted, Messageboxbuttons.okcancel, Messageboxicon.exclamation,messageboxdefaultbutton.button1, messageboxoptions.servicenotification) ==dialogresult.ok)
{//do some useful things}
Parameter messageboxoptions uses another parameter and the servicenotification is not very different and has not yet found its difference
Using this method, you can send a visual notification to the server side by the client, but you cannot use Windows controls. This usage has a certain use, but it is very narrow.
As for where it will be useful, you have more experience!!
But I feel very wonderful!!
