I wrote this:
Private Sub TextBox2_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox2.KeyDown
If e.KeyCode = Keys.Tab Then
MsgBox("Tab")
End If
End Sub
Why it doesn't work when I press tab on my keyboard?
I need to be able to send keycode keys.apps (windows context menu key) to an application. Surely if I can detect the keypress, there's a way to send the keypress, right?
What I'm doing is having a 3rd party app save a screenshot and the only way to have it do so is through its right click context menu.
So I opened 2 forms, Form2.vb and Form3.vbNow I put this:
Private Sub Form1_PreviewKeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles Me.PreviewKeyDown
If e.KeyCode = Keys.F8 Then

I have an application which I am trying to implement shortcut keys in. The application contains a main window from which dialog popups can be opened. I am having difficulty implementing the shortcut key functionality on the popup windows. I have the following code in one of the popup windows, and even though the first three key entries are the exact same as on the main window (except for the actual button names), which works, the same code does not work on the popup.
Private Sub frmInduction_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.Control + Keys.S Or e.KeyCode = Keys.F5 Then
btnAccept.PerformClick()
[code]....
I am opening the popup window with the following code- is there any way that the problem could be caused by how I am opening the popup?
Using frm As frmChangeValue = New frmChangeValue
frm.ShowDialog()
End Using
what keycode is the dot(decimal) ? i found Keys.Decimal but thats the one on the numpad, what is the one near the question mark on ur keyboard?

I'm tying to create a form with two buttons. Now, I want to be able to press two keys on the keyboard and have one of the two buttons activate So, instead of clicking Button1, I pressed Control + C and it will say "Comment" and instead of clicking Button2, I press Control + U and it will say "Uncomment".

The problem I keep running into is that the only way for the buttons to actually work is if they are already selected (Or, the last one clicked will work but the other will not). Then the keycode will work for them. How do I make this work without having to click on the button prior.
I've reviewed the other posts regarding this subject. I'm using VB from Excel and the function keys are not working. I'm running Windows Vista Home Premium with Office Ultimate 2007 Looks like Excel is running VB 6.5So, this used to work for me...I've used the debugger quite a bit. When I try the solutions suggested Tools->Options->Keyboard (after checking check-box to show all settings) when I click on the box just below "Apply the following additional keyboard scheme" the only item in the list is default. There is no selection for VB 6 or anything else for that matter.
View 2 RepliesI have a Window with Keybindings in InputBindings defined. They work the first time and when i set the focus on any control on the form.But when a Messagbox is shown and I press "OK" they shortcut keys don't work until I set the focus on a control in my window.

The output WILL be 189 when I press the - sign. But when I check "Keys.OemMinus" it stands for 189 and when I replace "Keys.OemMinus" with 189 it won't work either!
I checked the Resources file and it's correct. The picture just doesnt change, only shows the last pressed button...

But I also have a button to send my program to the System tray like so:

View 3 RepliesI am developing a vb.net media application using Windows Media Player which is working fairly well. However, I am having problems where the Function key handler will stop working after doing anything on the media control panel, i.e. mute, move the slider etc. So long as I don't touch the panel everything continues to work. I'm using the function keys to pull up menus for selecting other media and if I do anything with the control panel I can no longer display the menus.

View 6 RepliesIt appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]
