MouseEventHandl er != this.controlnam e.MouseEnter ?

SeaNICK

I am trying to figure out how to use MouseEnter or MouseLeave events, and be
able to use the EventArgs to determine where the mouse cursor is. To my
great confusion, the MouseEnter and MouseLeave events are not
MouseEventHandl ers.

so am I missing something, or is my .NET install messed up? it seems to me
that an event caused by a mouse being somewhere on the screen, should have
MouseEventArgs attached to it, not System.EventArg s.

but then again, maybe I am expecting too much, that the .NET framework be
logical. anyone have any advice on how to get this done, or should I just
assume events arent going to help me here and figure out how to determine
the location of the cursor manually?
thanks

Nick,

You are right, the MouseEnter and the MouseLeave events do not have
position information associated with them. However, you can get the current
cursor position by calling the static Position property onthe Cursor class.
This will tell you where the cursor is in relation to the screen.

Because it is in screen coordinates, you have to convert them to local
coordinates (in relation to the control). In order to do this, you can pass
the coordinates to the PointToClient method on the Control class.

Hope this helps.

Request("controlname") can use for both GET and POST protocol??

by: Matt | last post by:

If we use GET protocol, we can use either Request("controlname") or Request.QueryString("controlname") to get the data entered by the user. But if we use POST protocol, we MUST use Request("controlname"), and Request.QueryString("controlname") won't work. I think Request("controlname") means Request.Form("controlname"), which is used for POST protocol. But seems like it works for GET protocol too. Here's the code I tested. <%

probably wont get a response on this, tab question

by: Paul | last post by:

Hi, noticed high activity on this newsgroup as the last few posts I have made have not received a response. Anyhow I noticed that with a .NET web application when the webform opens if the user hits the tab key it goes to the address bar at the top of the browser. I would like it to go to a control and have set the tab index to 0 and 1 but still goes to the address bar. Thanks. -- Paul G Software engineer.
