 		Apparently, I have several buttons on a form. To have an efficient code, I would like to just get the object name if I mousehover it rather than make a mousehover procedure for every button. So how do I do it? I tried GetChildAtPoint but it didn't work. HELP.

 		You need to register a MouseHover event for that and every other button. I don't think there's another way to do it (I might be wrong, but I don't see a problem with registering an event for each button)

 		How about this code:

// php:
$tc = "JavaScript:fieldHover($x,$y)";
<td width=\"24\" height=\"24\" onhower=\"$tc\">field</td>
// javascript:
<script language="JavaScript">
function fieldHover(x,y)
{
}

So with php you can make a for loop that generates the fields with required javascript "onhover"(s)


I hope that helps...

 		Thanks, I'm using VB.NET . And I need a code that will show in a msgbox the name of the object the mouse cursor is on. Like when I hover on top of button1, a msg box will appear and say "You are on button1"

 		You could try asking in this .Net forum:

 		In VB.Net you can use the same code for multiple events. Try looking for the events button in the property window of the controls you want to mouse over and just set the mouse over event to the same sub procedure. this may or may not be what you were looking for but it makes it so you don't have to rewrite the code over and over.

 		But that would take >30 lines of code. I'm looking for a
Get Object at (MousePosition()) type of function.

 		Would it be possible to do something like this in VB:

loop arrayOfControls
control.onhoverCallback = callbackfn

then the callback fn:

callbackfn(thiscontrol)
do something with this control

 		For a .NET form, if I was trying to keep the lines of code down, I would probably do something like this.

On each button/item, put my help text in the tag of each button.

Then, create a single method that every button's hover event points to (shift-select all of the buttons at once, then point them to this event handler that you create):

Private Sub Generic_MouseHover(ByVal sender As System.Object, ByVal e_
As System.EventArgs)
StatusBar1.Text = sender.tag.ToString() ' Or however you want to handle the mouseover thing
End Sub

Sorry, I'm a C# guy, not a VB.Net guy, but that's some of how I would do it. You might have to cast the sender object to be a windows form object in order to get access to its tag property (though after you cast, don't forget to check to make sure that it's still valid).

Sorry I can't write you more code -- I could do this all day in C#, but I just don't know VB.Net syntax.

 		i'm going from old vb6 code here... but can't you use a control array and just grab the index from the event?

 		Thanks. But the code above just points to the main form, not the individual objects.
