I'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?
how I can detect the mousedown,mouseup etc even outside my application using vb.net? I have an API here,but,doesnt seem to work the way I expect it to..
VB
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
[Code]....
Should that API be modified to be used or something?? or what should I do to capture the mouse click events..both left and right buttons...
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.
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.
I'm just wondering if it's possible to add the mouse when capturing the screen or monitor in vb.net?
because I'm doing a project that would record the screen and I'm actually successfull doing that by capturing the screen and include it in a timer, but my only problem is the mouse or the cursor isn't showing.
below is my sample code. Dim ScreenSize As Size = New Size(TotalScreenWitdh, MonitorHeightArray(0)) Dim BMP As New Bitmap(TotalScreenWitdh, MonitorHeightArray(0))
I have a NotifyIcon (named TrayIcon). When I right-click it I get a menu. When I left-click it I want the form to be shown when it's minimized or hidden. But I can't find a way to get the latter done.
Private Sub TrayIcon_MouseClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TrayIcon.MouseClick If e.Equals(MouseButtons.Left) Then Me.Show() End If End Sub
When I debug, "e" shows "almost" same value ({X = 0 Y = 0 Button = Left{1048576}}) as"MouseButtons.Left" (Left{104875}) in the quick-watch window, still the Me.show is passed. I think this has to do with the X and Y, and "MouseButtos.Left" is of the type "System.Windows.Forms.MouseButtons" and "e" is of the type "System.EventArgs", but I have no idea how to get the right comparison.It's partially working though. When I leave out the if statement and only the Me.Show() is left, both right and left-click make the form pop-up. With the if statement, it never shows up.
Im Using VB 2008. I have MsgBox() statements in all Mouse & Form Click events to TEST & NOTHING FIRES during Form Load when I click on Form or Button Controls !!! The Form Load event contains code for Displaying the Label.Text control many times with changes in the Text to simmulate annimation.
Anyone 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?

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'd like to start by saying that simply though searching, DreamInCode has taught me alot about VB.NET. In fact, I would imagine without DIC as a resource, I probably wouldn't have been able to move forward and learn most of what I know now, just because I got stuck on some things here and there.Anyway, I searched around for information regarding how to "capture" a minimize event in VB.NET. I am working on the GUI for an application that I would like to have minimize to the system tray. Currently, instead of accomplishing this with the minimize function, I do it on the FormClosing event like this:
Private Sub MainFrm_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing 'Cancel the attempt.
[code]....
That code works, and upon making the form visible again with Me.Visible = True the form is restored to its original position. However, prior to the form being hidden, the window manager draws a minimize and restore effect before eventually hiding it. Any change to the WindowState _after_ hiding the form does not appear to have any effect, so when the form is unhidden it is still minimized.is there a way to capture Minimize events, and when captured, is it possible to cancel them in a manner similar to what I did with the FormClosing event?
Is it possible to capture a mouse click anywhere on a form (both on the form itself and on any control) without putting code in each control? I want to reset a timer/timeout when the user hits a key (which I have working no problem w/ a combo of
Apologies as this has probably been answered a million different times a million different ways already. I'm trying to control the mouse. I wish to move the mouse to a given pixel position (x, y) and cause a click. I don't want this to be limited within a form, as I want to control another application. I'm using VB 2005.
The GetAsyncKeyState Api does'nt recognizes the mouse wheel rotation, I see.Is there way to control the mouse wheel rotation (always, not only when the pointer is over a form of mine) with a simple API, without to Hook the mouse?
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
Im trying to capture the result of a combo box and time/date stamp this to mysql. I have a working connection between the form and the db able can anyone tell me how to achieve this?
have the following code, it works sometimes but other times when a form is minimized/Restored Down it will freeze, doesn't produce an actual error in VS but just freezes and does nothing..
The code captures a current form, the forms title, process id, a pixel color etc
Public Class Form1 Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
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]...
