VS 2005 Disable KeyPreview For One Particular Textbox
May 15, 2012
I have set KeyPreview Property of the form to True and in the KeyDown event capturing the 'Enter' key to navigate to the next control on the form (using Me.SelectNextControl). But for one particular textbox i dont wish to perform the form's keydown event instead i want that when the user keys ctrl+enter it should perform some particular task. I have noticed that when the keypreview is on the keydown event of the textbox isn't executing.. The following is the code i have used for textbox keydown

In my WindowsFormApplication I have a ToolStripTextBox. I want this to get the focus and have all its text selected when the user presses the "i" key - no matter what control has the focus. That's easy, I thought, if I set the form's KeyPreview property true (originally I did this in the FormDesigner, but doing it in the form's Load eventhandler makes no difference) and have the following KeyDown eventhandler:
Private Sub Main_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Beep() ' For debugging only
Select Case e.KeyCode
[code]....
But this does not work!? The above Sub is called only when the ToolStripTextBox has the focus and only AFTER the event has been handled by that control.

I set the HourGlass, disable the button (to avoid ppl that are too used with FPS games), do the serial communication bit that last a couple of seconds, then the set the mouse back to normal and re-enable the button.And I have a few more like those through the software using text boxes or drop-down menus.[code]My form is set in design time to be KeyPreview = True and I even tried to set it again after the Click. The routine is simply not called and the ESC key on the keyboard does not hide the form anymore.

As quick solution to the user wanting to be able to open a particular form from any other form (in a large application with many forms, not an MDI app), I added KeyPreview to each form and corresponding KeyPress event so that said form will open (ShowDialog) upon pressing F12 from all these other forms.
Since this update has been in place, the user has been getting intermittent (maybe 2 or 3 within the course of a workday) but nasty errors such as "exception has been thrown by the target of an invocation" and the dreaded "out of memory". Is there reason to believe (off the top of your head) that the KeyPreview could be causing this?

I'm currently working on "transferring" my vb6 application to vb.net. I'm doing a complete rebuild from the ground up - which allows me to address issues that have arisen over the life of my vb6 application and I'm also learning .net as I work. My primary concern though, is that on one of my forms I display all the information about a customer (Name, Address, Notes, Phone Number, Assigned Salesman, etc.) in VB6, I put all the textboxes in a frame and disabled the frame so they boxes looked "normal", meaning there were still white with black text. In .net, if I add the textboxes to a

When I step through the code and pass the line "ChkBox.Enabled = pbEnable", the Enabled value does not change. In this case the state before the change is False. pbEnable is True.[code]

I'm quite new to VB.net (and VS 2008), so I'm afraid my question might be basic, but I'm not sure how to solve it.I have a winform with three textbox fields and a button. All textbox fields must be filled before the user can click the button to continue. To this end I would like to disable the button as long as there is at least one empty textbox.
If I had only one textbox field, it would be easy for me to do. In the Textbox1_Leave event I would check if Textbox1.Text is not empty and if so, set Button1.Enabled = True.But what should I do if I have three textboxes? Have three event handlers, one for each textbox? Or is there a way I'm not familiar with?
