Keypress - Javascript

Hamish

I am trying to detect the up and down keys on a key press function, but they
do not seem to generate a keypress call. Is there another event generated
when these keys are pressed

Thanks.

PS Apologies if this appears as a double post, but the news server I used
originally does not seem to propagate most other news servers.

document.onkeyp ress will return your basic functional text keyboard. When
you press an alphanumeric key you will get it's lower case value. When you
press shift and an alphanumeric key you get the upper case value or in the
case of numbers the corresponding shifted characters. If you need to trap
other key events like the up/down arrows or the backspace etc you need
onmousedown or onmouseup and the correct browser feature detection since
there is no standard for DOM Level 2 AIUII. Hope this link helps.

consume keypress events

by: rege | last post by:

Hi, I have two applications developed in C# say A and B. When user presses key "L" with applicaition A active , it causes a keypress event which causes application B to run. Application A then waits for application B to exit. On exit from Application B the focus shifts back to application A. The problem is if user presses L more than once, say thrice, then three keypress events are generated. Therefore application A starts

Keypress event back to caller from control

I have a VB.NET user control that I wrote - this control has three or four other controls on it (textbox, combobox, datetime picker, etc). Now, whenever the control is on a form and the user enters anything into the textbox (for instance) I trap the keypress event to handle some stuff (i.e. if it is an enter key, etc). Now, once I am done with handling the keypress event for the textbox, I then need to pass that keypress event BACK to the...

How can I throw out (handle) an ENTER keypress for an AcceptButton?

by: Adam J. Schaff | last post by:

I have noticed that if a user closes a form via pressing return (either while the OK button has focus or if AcceptButton is set to OK for the form) then the "ENTER" keypress event fires ON THE CALLING FORM! This is very bad for me, because in my application, Form1 responds to an ENTER keypress by calling Form2. If the user closes Form2 via an ENTER, then Form1 just reopens it again, kind of trapping the user in Form2 (they can still close...

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
