Unicode Detect Non-English KeyPress
Jan 22, 2012When a user types into a VB.Net textbox, I want to detect the key press (assuming I cannot read the text from the textbox after its written). This is easy for English (by using e.KeyChar or Keys.[A, B, C, ...etc]). However, if I change my default keyboard in Windows from English to another language, say Arabic or Farsi, still the English characters are detected (although Arabic or Farsi is being typed in).

IDE :: NumericUpDown Control And The KeyPress Event?
Aug 9, 2009As part of a program that I am composing, the user needs to enter a value by way of a NumericUpDown control on one particular form. Once this and other criteria have been evaluated, the program will then move to the next "step" of the program. If they use the spinner built into the NumericUpDown control, the event is fired on every change and that's all well and good, but if they double-click the value in the control then type the value in manually, it doesn't fire until the control no longer has focus. I can't depend that this might be the case however. Using the "KeyPress" event, I can in fact know when the control has focus and the user has typed but what I cannot seem to get it to do is to get the control to "read" these keystrokes as values until the control loses focus.
View 3 RepliesSimulate Keypress In A WebBrowser Control?
Sep 23, 2010I have a VB.NET program that has a WebBrowser control on one of the forms. I need to have the program automatically access some data on a website, so I need to log in using the available Java interface.
The simplest way to do that seems to be to simply type in the WebBrowser; the Java code will automatically accept that into the correct text field. The program must remain unfocused while this is running, so SendKeys is not an option. Therefore, I'd like to use SendMessageA to tell the WebBrowser I'm typing in it. I've tried using KeyDown and KeyUp as follows (to send the keypress "0", in this case), but that isn't doing it.[code]...
IDE :: Using KeyDown And KeyPress Events On The Same TextBox Control
Jun 4, 2009I have a TextBox which Is allowed only to read certain characters. I use KeyPress event to handle this event. I understand that The KeyPress event does not handle the pressing of the DELETE key on the keyboard. I do not want the user to be able to delete characters in the txtbox by using the DELETE key, I want the user only to be able to use the backspace key. I am writing this code in Visual Basic 2005. The following code appears to work in handling the DELETE key, but I am concerned that I might get bitten by the fact that I am using KeyDown and KeyPress on the same control (txtSource).
private sub txtSource_KeyDown(byval sender as object, byval e as KeyEventArgs) handles txtSource.KeyDown
IF e.KeyData = System.Windows.Forms.Keys.Delete then
e.handled=true
end if
end sub

VS 2010 Custom Control KeyPress Event
Jun 20, 2011I was asked to create an application that has a custom control that acts as a button. I managed to do almost all the requirements except the one for the KeyPress event. The customer wants to click the "Alt + C (for example)" to trigger the button click event in this case for a Cancel button. I did the code and it works fine ONLY when that custom control has the focus on it. But when it loses it, it doesn't. I don't know how to make the form accepts that KeyPress and sends to the custom control. I tried to set the form's KeyPreview property of the form to Ture but it didn't work too.
By the way, I know that it would work by writing the code in the KeyPress of the form but that's not the requirement because the user control will be used as a standalone component for many projects.
Forms :: Multi-line Textbox And KeyPress Event Unusual Behavior?
Aug 13, 2010I have several multi-line textboxes that I want to lose focus (i.e. when the user presses the right arrow key) but the control wil not relinquish the focus.Simply put, I first verify if the selection start is at the end of the text, if it is, and the user presses the arrow key, it should move to the next textbox. some debug.print code placed in strategic locations indicates that the target textbox gets focus and immediately loses it and the source textbox gains focus once again. Essentially not allowing the textbox to lose focus.
Select Case
Case Keys.Right
tbRight.Focus()
[code]....
After changing the source textbox multi-line property to false, it behaves as expected. Is this a "feature" .. surely I don't have to resort to "SendKeys"

Jan 26, 2009Ok before I get flamed hear me out. I have a form with panels containing tablelayoutpanels containing various amounts of controls that alternate visibility. On the form in its entirety I am looking at roughly 3200 controls most of which are radio buttons.
Now that being said, I am trying to figure out a way to capture what control (mainly radiobutton) is being clicked on through the forms events. So far my attempts have failed with mousedown, mouseclick, etc. Yes I know I can use the "handles radiobutton1.Clicked" event directly. However with that many radiobuttons....I know that there has to be a better way to do this. An API, windows hook, something. So far my efforts to find an alternative method have failed.
