I was wondering if Visual Basic could emulate the pressing of keys.
I was thinking of a program that did this:
When I press a button (Button1) it would start a timer (Timer1), then press the V key on the keyboard and then type what was entered in a textbox (Textbox1), then press the Enter key. After doing that, repeating that action a second or two later, but saying what is in (Textbox2).
Could this be possible? If yes, please respond.

And use:

For special keys.

If Esc key is pressed in
MODIFY FILE test
window, Visual FoxPro shows
Discard changes
Yes No
prompt. How can I replace this with
Do you want to save changes to test.txt
Yes No Cancel
prompt ?
A Yes/No/Cancel prompt appears if I click on the close button in the upper right corner of the close window.
Is it possible to force it to appear when I press ESC also ?
Can ON KEY LABEL esc or some custom edit windows command be used or is there some other solution ?
Yes, you could solve it with ON KEY LABEL esc someFunctionCall(). The function has then to display the dialog you desire, and you also have to write the logic whether you pressed Yes, No or Cancel. Also keep in mind, that you have to issue ON KEY LABEL esc again, so the dialog won't show up everywhere.
Another solution would be hitting CTRL+S before you press Escape. With another dialog you have to move the mouse or press another button anyways, so there is no time to safe here.
I've run into a rather specific problem where I would like to send a key press while having a modifier pressed without the modifier pressed.
Basically, I press Option+F4 and want to send Command+F, not Command+Option+F.
Can it be done?
How can I create a GUI element like the one of type "Input" that would register current keyboard keystroke, but I'm not talking about any letter or number, but rather special buttons like CTRL, TAB or Enter?
As far as i know there is no special GUI element handling that.
There are some "workarounds" like
When something gets written check if CTRL (or anything else) is pressed
_IsPressed()
Catch if you press CTRL with Hotkey and then make a Funktion to insert it into the Input
HotKeySet({CTRL},_insertCTRL);
Does one of these work for you?
If I press a shortcut combination (such as Ctrl+M) – VS waits for the second one. What if I want to cancel it? (e.g. if I mistakenly press the wrong letter and am not sure which one.)
It just waits, with the "(Ctrl+M) was pressed. Waiting for a second key of chord..." in the bottom of the screen.
How do I cancel it?
Press Escape. Usually it is not tied as a second keystroke.
I normally press Esc .
I don't know of any keyboard shortcut where Esc is the second key press.
There aren't many visual studio Chords that end with Esc so just hit Esc it'll say The key combination is not a command but it prevents you from performing a valid chord.
Another option is to record a no-op macro and assign it to Ctrl-M, Esc. It will say running macro at the bottom quickly and go away.
You are in Dvorak Keyboard mode in windows. Press Ctrl+Shift to get out of it...
Hey everyone, thanks for all your help so far, I've learned a whole lot in a short amount of time.
What I've done so far is to create a small calculator program and it works nicely. To complete this version of it, what I'd like to do is make my "keys" on the calculator interface accept input from my keyboard presses. So, for example, if I want to add 2 and 4, instead of clicking my "2" and "4" buttons, I can just press them on my numeric keypad instead.
I know it has something to do with giving my buttons focus but I can't figure out how to make them respond to keydown events.
I'm looking around on the apple developer documentation as well, so if I find the answers before you guys can then I'll try what I find out, and if it doesn't work I'll post with my progress.
Again, thanks everyone for your help!
You can set the key equivalent in interface builder. Click on the button in interface builder open the inspector and open it to the first tab. Under the first section there is a Key Equiv: and a gray box you can click on. Click on it and press the key you want to press it.
If you're using interface builder, just set the "Key Equivalent" field to be your number.
