Imports System.Math
Public Class Form1

I have a SplitContainer control with DataGridView and WebBrowser controls. I'm trying to call focus to the WebBrowser whenever I hover over it so I can use mouse wheel to scroll. I can do that with the DataGridView since it supports MouseHover, but what can I do with the WebBrowser control to achieve the same thing?
View 10 RepliesI've got a textbox with a mousehover event and that event will only happen once and then I have to move my mouse out of the text box before it'll happen again. Is there a way to reset the mousehover event 'trigger' so that it happens as many times as I want?
View 7 RepliesI have a project with Control arrays that include over 200 controls.
I could use Tipster to define a Tool Tip or I could assign a Handler for the MouseHover event & use the handler to provide a help remark.
Would the Tipster approach result in the use of more memory/code than the MouseHover approach to this job?
I have created some labels and i need them to display a popup message when you hover the mouse over them at runtime. I searched for a solution but i only found out how to display popups when hovering over a button and also the code for that was overly complicated.

I have a form with a picturebox called Chartbox and I'm trying to fire a mousehover event when the mouse is over a drawn region (Cregion). My code (see above) is not working.
In my program I have a picture "biedkrt". I like to test what x an y values I must use in my program.
In the forums I found the following routine:
Private Sub Biedkrt_MouseHover(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles biedkrt.MouseHover
[CODE]...........
However, this code is not accepted:
Error 1
'X' is not a member of 'System.EventArgs'. C:VBtestMayBridgeMayBridgeForm1.vb
5849 43
MayBridge
The same for Y. I tested when I commented the Label line out, whether this routine is executd when moving the mouse into "biedkrt" which is the case.

I have a number of UserControls that have the same event .
When I use an Object instead of UserControl, I can not use Addhandler.
Here is the simplest example of my problem: In this example error is "TextChanged is not an event of Object"
Dim obj As Object = TextBox1 AddHandler obj.TextChanged, AddressOf text_changed_event I have to use this structure, because in a FOR loop I use some different UserControls as obj. All UserControls have the same event.
Is there a way to use this structure without error?
Maybe there is a way to define a new object that covers all my UserControls.

I have a button in a grid that I created programmatically. The button edits some data in a table using data in a hidden column of the grid that the button is in. Normally I send a hidden field the row data using javascript onclientclick of the button then make the changes to the database using that hidden field.
