If not, any good articles on how to acomplish this yourself?

Thanks! Re: How to create a shortcut key for a control in C#? Kir Birger5-Dec-04 5:46 Kir Birger 5-Dec-04 5:46  i'm not certain what you mean. but if i understandyou properly you want a control to gain focus when a button is pressed? well i havn't done anything with tabs (never needed to) but here's the general code. goto the events list on the form that the tabs are on and create a KeyDown handler by double clicking on it. in the handler do something like this... if(e.KeyCode == Keys.____) { tc.focus(); } e being keyeventargs, tc being your tab control. i hope that helped a bit Re: How to create a shortcut key for a control in C#?

Re: trapping keystrokes Kir Birger5-Dec-04 5:51 Kir Birger 5-Dec-04 5:51  your custom control needs to have a keydown handler. if possible make it extend the Form class, then you can just set the AcceptButton. Re: trapping keystrokes Anonymous5-Dec-04 8:03 Anonymous 5-Dec-04 8:03  i guess my main problem is is that a my control uses a text box thats not multiline i can trap the enter keystrokes but it beeps every time i have it set to accepts return but since its not multiline it beeps how can i get around this without making it multiline Re: trapping keystrokes Kir Birger5-Dec-04 8:09 Kir Birger 5-Dec-04 8:09  i don't understand what you're saying. could you explain exactly what you're doing? if you have a regular single line text box, it will always beep for return strokes unless you use a keyboard hook that intercepts the enter keystroke but that's icky. From what i understand you might HAVE to use keyboard hooks though. the additional problem is that you don't want the keyboard hook to trap EVERY enter keystroke (per se if you're in another app). to solve this you have to run the hook, when WndProc is called you have to check if your control has focus. if it doesnt you have to pass the message on to the next window handle in the chain to recieve the message. If your control has focus you do whatever you want it to do and don't pass on the message. Re: trapping keystrokes Anonymous5-Dec-04 11:10 Anonymous 5-Dec-04 11:10  i have a control with a text box and a button and when the user hits enter in the text box im making it trigger the button click event but it always beeps :P Re: trapping keystrokes Kir Birger5-Dec-04 11:42 Kir Birger 5-Dec-04 11:42  allright. so lets take a look at it as a timeline. -You click on the textbox. -you type something -press enter. -> -the KeyPressed message gets sent to a list of handles ending in the text box. -text box recieves it, it's not multiline so it error-beeps. your goal is to intercept the message, handle it yourself, and stop it from being passed. do you need some help writing a global hotkey / keyboard hook? Re: trapping keystrokes Anonymous5-Dec-04 19:01 Anonymous 5-Dec-04 19:01  i can get the keystroke just fine and make it do what i want i just cant stop it from beeping Re: trapping keystrokes Kir Birger6-Dec-04 7:01 Kir Birger 6-Dec-04 7:01  You have to catch the keystroke another way, that's the point. as long as a single line messagebox recieves the enter-press, it will beep. you have to stop it from getting it, or you can write your own control how can scan port in c# mehdidj4-Dec-04 17:08 mehdidj 4-Dec-04 17:08  hello hellp me scan port in c# Re: how can scan port in c# Alex Korchemniy4-Dec-04 18:16 Alex Korchemniy 4-Dec-04 18:16  aren't you the same guy that wanted to know how to write a hacking program in c#??
