Global MouseClick Handler?
Apr 17, 2010
I've been trying to write a utility program that enables you to click a certain number of times and having a specified program open up when that happens. Ex: If I consecutively click 5 times it will open explorer, 6 times will open outlook, ect.I have the entire program writen out, the only things thats stopping its completion is that I can only log clicks that happen ON the form, not on the desktop, or within any window (globally detecting mouse clicks, as opposed to only on the forum
Code:
Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click

I have a piece of code that i want many ListViews to run throughout the app at ItemUpdated. I'm sure the same can apply to many other control-events.How can I hook up a certain listviews ItemUpdated event to a sub in a class module?
here's my class module Public Class ControlParts
Public Shared Sub LSVItemUpdated(ByVal sender As Object, ByVal e As ListViewUpdatedEventArgs)
Dim lsv As ListView = CType(sender, ListView)
lsv.EditIndex = -1
End Sub
End Class
Now if i add OnItemUpdated="LSVItemUpdated" to my ListView's declaration I get an error that 'LSVItemUpdated' is not a member of 'ASP.admin_order_aspx'. Well, I don't want this on the page. I wan't this to be globaly accessible. I could in the code behind call the LSVItemUpdated, but that will beat the whole point off.

I want to define a global exception handler for unhandled exceptions in my console application. In asp.net, one can define one in global.asax, and in windows applications /services, one can define as below
AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyExceptionHandler);
But how can I define a global exception handler for a console application ?currentDomain seems not to work (.NET 2.0) ?

I have a Windows Form application that has a global error handler to display unexpected errors.
Namespace My
Class MyApplication
Delegate Sub ProcessParametersDelegate(ByVal sender As Object, ByVal args() As String)
[code]....
1) for the same deployed code, I SOMETIMES get line number in the displayed StackTrace error message and sometimes do not, even when the error message includes source code that I have written rather than a referenced binary. The project is compiled with a DEBUG configuration.
2) The application strangely minimizes to the tray when the error occurs (I thin it is unlikely that anyone can diagnose this issue w/o my more code posted, but I'll mention it anyways)
3) When I try to intentionally raise an error by, for example, dividing by zero hoping to test by global error handler, I get a dialog error message from the interactive debugger rather than jumping into my global error handler (which i want to debug because there is more to it than I posted.) Do you have any idea how to triggerand force teh execution of the global event handler?

What I want to achieve is, getting the current position of the mouse when it's clicked on the form (so also on any object on the form)I can get the position with (this code runs in Timer1)
Dim MousePosition As Point
MousePosition = Cursor.Position
Button4.Text = MousePosition.X & " " & MousePosition.Y
But how do I capture an an overall Click event, so when the mosue is clicked the timer stops?

With the following code, I am creating a child form when my main form loads:
Public Class Form1
Dim cForm As New System.Windows.Forms.Form
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
Once it loads, the main form doesn't seem to handle the mouseclick event. Is that because the child fom is showing, and somehow IT has to handle the click event (even though I'm not clicking within the boundaries of the child form)?

I have an ActiveX component (for mapping) I am using that I need to do an action on a mouse click, but the event isn't exposed. Internally, the class seems to fire an event, as it has a LastPointClicked() method that you can call that returns the map coordinates of the last point you clicked on. I am trying to find a way to center the map on the point clicked. I could fudge it with some kind of timer that just checks to see if the LastPointClicked has changed and center if it did,

For some reason I have always used the SelectedIndexChanged property to take action when something is clicked (I guess because this is the default property? ie when you double click the listbox this is what you get). However I have often come across problems when I try to unselect all the items in the listbox by calling

I have a treeview, and lets say in the treeview I have the nodes "Textbox1", "Textbox2", and "Textbox3". Also on the form I have 3 textboxes. What I want it to do is when I click "Textbox1" in the tree, to select all text and bring focus to the first textbox. So on the AfterSelect event of the treeview, I find out what node Im on, and what textbox to go to, then I say Textbox1.Focus() : Textbox1.SelectAll().When I use the keyboard and navigate to that node, it works. It jumps the focus off of the treeview and to that textbox, selecting all it's text. Works fine.But when I click on it with my mouse, it doesn't. It does select the text, bring focus to the textbox, but immediately brings focus right back to the treeview. (you have to look really close to see it) I'm thinking there's some mouse event that is bringing the focus back to the treeview, but not sure what.

I have spent the last hours trying to make an easy fix for this. Setting it to enabled=false is no good in this case. What I was looking for is a way to prevent the user to place the cursor in a multiline textbox. This is a read only textbox, and the user can't type anything in it, but for some reason he can still place the cursor in it, that is what I try to prevent.

I've noticed that in VS2008 the Mouse_Click() event is not firing for the right mouse button.I create a standard WinForms button called "btnMouseEvents". Wire up the MouseClick event. The event fires for the left button but not the right.
Private Sub btnMouseEvents_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles btnMouseEvents.MouseClick
MsgBox("Mouse click. Button = " & e.Button.ToString())

I am trying to send a mouseclick via the code below and it works fine. But I was wondering how would I send a "virtual" mouseclick(It emulates a mouseclick at specified point but does not move the cursor)

I am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?

I have created a User Control and would like to be able to detect when the user clicks on the Form.I have seen this question which is related but the suggestion to use the the Leave event doesn't always do what I want because the focus doesn't necessarily change when the user clicks the Form (my control could be the only control on the Form in which case focus stays with my control).I want to be able to do something like this from within the User Control:[code]

I have a form, and the background color of the form is set to the transparency key, making the background of the form transparent. The problem I'm having, is that the form cannot recognize the MouseClick event (when I click on the transparent background of the form). I figured out that the transparent background is triggering this problem. When I shut off the transparency, everything works fine.My question is.. Is there any work around? I still need to use the form to be able to access certain objects that are rendering there, so I don't think I could use something like a "Panel" for example, because the objects will render underneath and possibly make them inaccessible.

just trying to work out some functions, like time delays and such and autoclickers.What I have is two command buttons and one textbox, and what I want this program to do is make a mouseclick according to the time inserted into the textbox (in milliseconds). e.g say someone types in "500", after button 1("START") is clicked, the mouse will click every 500 milliseconds, and button 2 ("STOP") will halt execution. Also, would this continue execution in the background, if i have other programs open? I've been able to make a program that has a timer which ticks at the specified time, I just can't get it to make the mouse click, i've tried "cmdButton.PerformClick" but thats not working,

I have a custom (inherited) TabControl which adds Drag/Drop functionality to it, so that one can drag the tabs around, either within the same control (to re-order them) or to and from other TabControls. I've noticed some time ago that my TabControl however was not raising its MouseClick and MouseUp events (or actually: it is not calling its OnMouseClick and OnMouseUp methods, which comes down to the same thing). I've been struggling with this problem for a long while and I finally figured out what is happening. I'm no closer to figuring out what to do about it though... The problem seems related to the drag drop functionality. I have this code in the OnMouseDown method (which is raised as usual):

Currently, when I double click on my current list, even if there isnt an item at the current mouses location, it calls the event and uses the last highlighted item. I know it is possible to fix this by using a selected index change event, but I require the list items to be double clicked

remove an event handler from within the event handler?
I have a class that gets data from a hand scanner. When the scan is complete and the data is validated, the class fires a custom "ScanComplete" event and returns the data in a custom EventArgs.
In the calling program, I'm creating an instance of the scanning class and adding a handler for the "ScanComplete" event. In the event handler I get the data that was scanned and then remove the handler.
It seems to be working but it feels wrong to remove the handler while I'm running inside the handler. Will this cause a problem?
