How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.
View 10 RepliesI have a Windows form in VS2010 with a rectangular area that I draw in with Graphics.DrawImage for best performance. I want to create a Mouse-move event handler just for that area (to change the cursor when the mouse is inside it), along the lines of handlers for the other controls on the form. But since the rectangle isn't a PictureBox or Panel or other control, I don't see an obvious way to handle it. A mouse-move event handler for the entire form could affect the performance of the app.
View 8 RepliesI'm working a program where I need to capture the mouse down even at the form level. I need this to happen regardless of where the mouse is clicked. The standard mouse event (see below) works fine if the mouse isn't over a control. However, when the mouse is over a control, the control gets the event before the form. I can generate an event to capture the mouse event for every control and the pass the event on, but that is ugly and requires way to much maintenance. Isn't there a way to tell vb that all mouse events go to the form?

I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown

Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.
I would like to capture a mouse move event, no matter what is under the mouse. I added a browser to my form, but the mouse move event isn't captured when the mouse moves over the browser.how can I add this event no matter what?
View 3 RepliesIn my project's Main form I have a picture box of size 1024*1024 which occupies almost 75% of my monitor screen. Now I have defined Picture box Mouse movement event with corresponding actions to be done for mouse mouse event over picture box. Now the problem is I have another button on my main form by pressing which an another form of size 520*170 pops up. I have set Me.Topmost property to this form. But even then if by I hover the mouse over picture box, this pop up form disappears (i.e. goes to back screen) and if at all i have to perform any action on this form I need click the Tab of the popped window on the task bar which makes this form visible. Worst case is if the user drags this form on top of the picture box and looses focus, then its impossible to get it(focus) back.
View 3 RepliesDoes anyone have a trick to catch when the mouse is over a listview column header ? As you know there is no native handler that would fire such event...
I have build a small routine that will be able to tell over which column the mouse actually is, the problem remains in which event to put it..
I have set the controls mouse enter and mouse leave events. My problem is that the mouse leave event fires if I mouse over any of the child controls (like the name box for example).What I need is for the mouse leave event to fire when my mouse leaves the entire control, rather than firing when I mouse over any of the child controls. Here are the events as I have them so far:
Private Sub DeliveryControl_MouseEnter(sender As System.Object, e As System.EventArgs) Handles MyBase.MouseEnter
Me.removeImage.Visible = True
End Sub

I am new to VB.NET, Now i'm working with Events in VB.NET, I have two event methods, Mouse Click and Mouse Down for a single button in a form, I have displyed a message in each of these methods but only mouse down event is triggered. Why Mouse Click is not triggered? Similiarly I Did the same for Mouse Enter and Mouse Move for a particular button, in this case both the events are triggered.
View 2 RepliesI've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

View 3 RepliesAnyone know why the Mouse_Leave event fires when you don't leave the control with the mouse pointer?Put a large button on a Form so your mouse pointer does not leave it easily.Then try this codeWhen you do, leave the mouse pointer in the middle of the button and then click the button.By the way, if you uncomment the 1st line of code in the Button Click event and comment out the MessageBox, this does not happen.Can someone please explain this behaviour?

View 2 RepliesI have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.

View 12 RepliesI'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1?

View 7 RepliesAs you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way

I just want to know if there any equivalent event (ADO. NET VS 2008) event as in MS ACCESS Form's OnCurrent Event.
The reason is I like to make some calculations based on some data bound controls with current datarow data when user clicked a row in DataGridView (or by using bindingNavigator). I've tried with DatagridView's RowEnter event. But some Data bound controls are not yet reflect the data of current datarow when that evet was fired.
In MSDN Help File: It says "RowEnter Event: Occurs when a row receives input focus but before it becomes the current row. "
I'm a really beginner so i want to know if its possible to make the mouse move to certain co-ordinates outside of your form and then click , and then pause before repeating.

just now I was trying to capture the F1 key on the form, but only managed when the form is selected, and I need to detect it in any form control. I used this code:
Select Case e.KeyCode
Case Keys.F1
MsgBox("Right")
e.Handled = True
End Select
i'm trying to trigger control events from outside the form that the control is placed. The idea is test of that control.
How this can be done.
For example I'm trying this

Dim testControl As Control

A few weeks ago I wrote a wrapper for the ServiceController control to enhance and streamline the base ServiceController. One of the changes I made was to add a monitoring component using the System.Threading.Timer object. On any change of status, an event is raised to the parent class. The actual monitoring works fine, but when the event is handled in the main form, my program abruptly ends - no exceptions, no warning, it just quits. [code]...
View 1 RepliesI'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).
I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?
