VS 2005 Creating A Mouse Click + Key Pressed Event Handler?
May 7, 2009
I have 2 listboxes on a form. Each listbox has a few items. As you know, I am able to have 1 item selected from each listbox, therefore making it 2 selected items from different listboxes.
I want to create a keyboard + mouse shortcut so I can de-select or change the selection mode of the listbox when Alt is held down and Left button on the mouse is clicked on the selected item. Here is the code that I wrote, which does not work.
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
If Control.ModifierKeys = Keys.Alt AndAlso e.Button =

I have a VB6 app that works correctly in win7.
I downloaded and installed VS2010 yesterday, and converted the app to VB2010.
The app works correctly except for one problem. I have a label array which has two event handlers defined, one for a double click and one for mouse down.
A double click is ignored and the mouse down event is raised. It shows the left button was clicked once.
If I comment out the mouse down handler, the double click event is raised and it shows left button was clicked twice.
What i want to accomplish is allow a user to double click an array element on the screen which then saves the number associated with that element and then click somewhere else to copy the data or alternatively, drag and drop the element to the new location.
The drag operation on the source element always triggers a mouse down, but so does the first of the two clicks in a double click.
It seems that none of the other newer events are raised, eg GiveFeedbackEvent, QueryContinueDrag, DragOver, etc.
So, how do I trap a double click and a drag start without using the mousedown event for the dragstart?

I 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.

I 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.

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.

I have an assignment to complete, that for the most part is half way done, the application starts with the number zero (0) and anytime the count button is pressed, the a one (0) should be added to the output label?
Public Class CounterForm
Private Sub countButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles countButton.Click
countTotalLabel.Text = Val(countButton.Text) + 1 End Sub
End Class

What is an "EASI" LinkButton? Why don't you just use an ASP.NET LinkButton? Try modifying your JavaScript method so that it returns "true" if you want the postback to occur...and "false" if you want it to stop. Then change the LinkButton to so that it "returns" the value that is returned by the JavaScript method... This should stop the postback from occurring (but then again I've nevers een an EASI LinkButton before.......)
<EASI:LinkButton ID="btnSearch" runat="server" CausesValidation="False" ClientScript="return confirmSearchOK();"UseSecurityLevel="True">Search</EASI:LinkButton> JavaScript modification suggestion:
function confirmSearchOK() { var planSel = document.getElementById("<%= ddlPlanID.ClientID %>").selectedIndex;

Basically, I have about 5 forms. 1 of these forms is the main program screen. I need to be able to use select case to navigate to the other forms, however I am unsure how to do this. I thought about using multiple buttons to each form using select case, but did not know how to implement this with the click event handlers for each button?

The event handlers in my parent class are never called though the events are raised in the child class.
The Code:

Public Event checkboxchangedEvent(ByVal checkbox1 As Boolean, ByVal checkbox2 As Boolean)
Private Sub checkboxchanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged

I've been working on a GUI in WPF which I'm fairly new to, having only used Windows Forms up until now. So far, my GUI is very simple: it contains two rectangles, each of which drops a shadow. The shadow creates an effect of rectangles "floating above the canvas" so to speak.
When one of the rectangles is pressed, the myRectangle.MouseDown event is handled such that the shadow goes away, thus creating an effect of the rectangle being pressed down onto the canvas, like a button.Similarly, when mouse button is released, the myRectangle.MouseDown event is handled such that the shadow reappears and the rectangle "floats" again. This behavior make them resemble buttons. Note, there a reasons I want them to be rectangles and not custom buttons.
[Code]...
If the pointer leaves a rectangle while mouse button is pressed, I'd like shadow to reappear. This is arguable simple, because theoretically in this case, any time myRectangle.MouseLeave is raised, the shadow should come back on, even if it was already there.If the pointer left a rectangle when mouse button was pressed, then came back while before the button was released, I want the shadow to disappear again. This one is what gives me problems. No idea how to do this.

I have a picturebox on the form, when it is clicked, I want the picturebox to fit the size of the form, which can be done by
pic.SizeToFit = true So, the picturebox will automatically change the size.But after that, I want to set pic.SizeToFit = false , I need this because the picturebox is a user control which has a image Pannign feature, and it works only when the picturebox.SizeToFit = false
I can not set it = false in the mouse click event, because I need set it = true, so the pic will change size.basically, what I need is: after mouse click event finished, change SizeToFit = false.One way to do it is in mouse click event, start a timer, after several seconds, set SizeToFit = false. Or, use a thread. It will work. But, is there a more elegant way to do this?
