Get Keydown On Application/form Load In .net?
Mar 16, 2009
I want to able to hold a key down while the application is loading and depending on which is being held down a certain form is shown. For example holding down shift and the opening itunes opens a little dialog allowing you set the library(or something)I can check whether the shift/Ctrl/Alt are being held down but i'd prefer to use the letters/digits.Such as hold 1 down to open Form1 and hold 2 down to open form 2.

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

I want to show a dialog box or form immediately after my application loads. If I place a .showdialog in the main form load event the dialog shows before the application shows.
I'm trying to give some user tips when they load my application.

I need to detect shift + arrow key in blank form. But it's not working. I also tried overriding IsInputKey method but it only detects single key press (like arrow key) but when multiple key are pressed it simply doesn't work.

I need to monitor KeyDowns outside of my application (probably running in a NotifyIcon) so I can detect a certain key combination to do something. How can I do this? I read somewhere before about using a process.

I want to make it so that no matter which control has focus, it will do my event. So that I dont have to write a keydown event for all 137 of my objects. Is this possible?

I have created a program which should perform a certain action whenever a certain group of keys is pressed at the same time. The program must be able to run in the background, or in the system tray or something. Essentially, this should work like the KeyDown event on a form, except the form in this case is everything.
I'm not certain if there is a way to do this directly from within the .net API, but if there is I certainly have not found it.

Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.Control Then
MessageBox.Show("aaaa")
End If
End Sub
As you can see, my form will check for when the control key is pressed down.But it doesn't work. Why?

I want to know how to do a keydown at form level. If I am not using Form Level the right way, this is what I mean. In my Form there is nothing.I want it so when the user presses a key that it will msgbox() something.As I said, there is nothing on the form what so ever No ComboBox, Button, nothing.

I am having trouble using keydown for the spacebar in a form.I would like the spacebar to start/stop a StopWatch that I have running. I can get that to work fine but whenever I am focused on another button it also executes that buttons function also.I know that is the default behavior for the enter key and spacebar but I would like to override that.

Imports System.Data
Imports System.Data.OleDb
Public Class Form1
Dim con As OleDbConnection
Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.

I'm using VB.NET (2008) and .NET framework 3.5. In my application I've got an on screen button that, when pressed, sends "00" as the characters [via SendKeys.Send("00")]. I also have a keyboard that has a '00' key that sends "00", two zeros, when pressed. I'm picking up the keypress using the form's KeyDown event - it fires twice, once for each "0" and works whether the on-screen or keyboard '00' is pressed. There's also a singe '0' on-screen button and key on the keyboard that sends "0".
I want to be able to treat the "00" as a single event. I.E. in the KeyDown handler, if the character is a single zero "0", I would like to check the next character to see if it is also a zero "0". If it is then I can handle it appropriately, but also need to remove it (from the keyboard buffer?) so that it doesn't fire the second KeyDown event. If it's not a zero then it should be left to fire the next event in the normal fashion.

when I added a textbox to my form, my keydown events no longer work. It seems impossible to get the blinking cursor out of the textbox so as to avoid targeting it. How do I retain keydown events when a textbox is added to the form?

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?

I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.
