Handle And Capture Event When Key Wheels Are Pressed ?
Jul 23, 2009
I have to handle a particular kind of KeyDown event. I have made a new virtualdesktop for my GPS Windows CE based thats launch an external program (like TomTom). I have to handle and capture event when key wheels are pressed (volume control). I know only like as "Private Sub Form1_KeyDown()" but this function works only when Form1 is focused... How can I continue to get and traps event when my TomTom is still running and focused?

I have alot of experience in working in VBA for excel, but not so much experience in creating my own structures so it's all still a bit foggy. I'm trying to capture the event for when the F1 key is pressed, not just when the form is active, but anytime the program is running. The code below expressing the handling is automatically generated for me in VB Express... But I'd like to change the situation to encompass anytime the program is open. I guess I have to reference events that happen in windows in general, but i don't know how to do it. I think i have to create the even in a class module?

I have a datagridview on a form. I have the .selectionmode set to FullRowSelect.
I use the datagridview.select to put the focus on the form. Pressing up/down arrows they navigate through the results.
How do I capture the enter button being pressed on the current row they have highlighted?
What I will do is take the ID field of that row, I just need to know how to capture the enter button being pressed in that datagridview.

is it allowed to use more than one Sub to handle the same event ? For example , may I have 2 separate subs to handle the Load event of a form ? Will they fight each other ?I have tested it and it seems to work fine , nevertheless I thought I'd ask you . In case you wonder , there is no great deal , I just want to copy the same lines of code in more forms so I am doing it just in favor of the looking aspect .

I am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)
When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".
How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.

I have a tabcontrol with 3 tabs. I can't see where any event is raised when I click the small tab area (where the name of the tabpage is). I see where an event is raised when I click on the tabpage itself. What is the event for the small tab area? I am getting by with a mousemove event over the currently selected tabpage.

I know the answer to this is out there somewhere, but my Google isn't being much help on this one. I am trying to make my combobox run an event when the enter key is pressed. Here is my code.

If e.KeyChar = Chr(13) Then
SearchEvent()

The problem is this is not very efficient. Now I would like to know if its possible to trigger a sub as soon a button D-sub of analog stick is pressed/moved. I've seen the following:

I've been searching for the answer for this all over, but I can't seem to find the solution. I have no idea how do this. A code that triggers an event after multiple command buttons are pressed in a certain order. For example: I press Command1, then Command2, then Command8, then Command5, then an event happens. It's kind of similar to entering a code to activate something.

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'd like to create a WebBrowser for the purpose of taking a screenshot of a website. Once its finished it will update a thumbnail image in a ListView. I'd like the whole operation to be done in the background so the UI remains responsive.I toyed with Creating the WebBrowser in a new thread and calling Navigate. I can use a loop to watch for the ReadyState of the webbrowser before I do the screencapture. However it will only continue with the thread if I use Application.DoEvents in that loop. I've never been a huge fan of doing this and would prefer to watch for an event instead. However if I add a handles clause to the WebBrowser it doesn't fire (I tried creating the WebBrowser in the thread, and also tried by declaring it as shared within the class scope).

Ok, so this is VERY simple to do IF I was working with a regular Textbox control. But of course, Microsoft does not have an "AcceptsReturn" property for a MaskedTextbox Control.
So, if the user finishes typing in the MaskedTextbox control and hits the [Enter] key.... How do I capture that key stroke with this type of control? Also, what if this MaskedTextbox is on a UserControl, not a regular WindowsForm?

I have the following code to control how a form is shut down. Specifically, when they click the red x at the top of the form. My question is, how do I control the minimize button at the top of the page. I want my forms to minimize to the information bar instead. I know how to send it there if I can capture the minimize event.

I've been searching all over and I'm either not searching for the right words or it just doesn't exist. I've got a datagridview (dgv) on a form with some textboxes that are databound to different fields in the dgv's datasource. I want to capture an event if someone changes a value through one of the databound controls so I can mark the row as modified. I've been going through the dgv events trying to capture something, but I can't find anything that fires when a value is changed. The dgv is read only, so the values can only be changed through the databount textboxes.
How to I know if someone changes a value in the dgv? Is there a setting in the dgv that will tell me if a row is modified?

Listening for an event from one program and capture it on another?is this possible, I'm asuming I would want to send a system wide event so I could capture it.My scenarioLet�s say I have this separate Splash animation (a series of png/bmp etc) but instead of having them in the main program itself I want them separate in a DLL/EXE.So how can I raise an event (probably system wide event I would imagine) letting the Main program know that the Splash DLL/EXE has finished it animation so the main app can continue?

I know generally it is not the best solution for a child to handle an event of parent. Take this for example; Mainform loads UserControlOne, UserControlOne handles all UserControlOne needs to. How ever we need a MenuStrip/ToolStrip. MainForm does not need to know much about what UserControlOne is doing. Other then receive some information on a statusbar. Right now events are controlling this.
The menustrip/toolstrip need to be able to speak to UserControlOne, for example when buttons are clicked on the strips. Would you; Allow the child to add a handler to capture the parents event? Move the MenuStrip/ToolStrip/StatusStrip all to UserControlOne so we can ignore all this event hassle? My Major concern with this is now we have taken all the head ache away from MainForm and crushed it into UserControlOne. Any suggestions?
