Continue A Program Unless A Key Is Pressed?

Nov 8, 2011

I am making a Tetris program and I have a 2d array 10 by 20 for the grid.I want the Tetris blocks I have created to move down one block every second unless the user presses "a" or "d" (to move left or right) then the block should move left or right whilst moving down.The problem is that I have created a loop for it to delay a bit but then it waits for the user to press a key until it continues the program. So the block will stop moving down and just stay where it is until they press something.I have been told that you can do this in C with something like if keyboardhit or kybd() or something then it will read the key but otherwise it will just skip that bit and loop round. So how can I do this in VB?

Make Program Wait Until A Button Is Pressed?

May 30, 2010

In my program, if something goes wrong an ErrorForm is supposed to show up and tell what was going wrong.

And if the error is a "fatal type", then I want the program just display the ErrorForm (which gives some information about the error), wait for a button press, and then close the program (terminate run).

In case of error, the form is displayed.. That's good.

But as the program is supposed to terminate after showing the error form, the error form disappears immediately after showing up (so it doesn't allow the user any time to read what's going wrong).

How can I make the program wait until a button press (on the error form) and then terminate?

Forms :: VB 2008 Express - Get The Program To Recognize The Key Is Even Being Pressed

May 3, 2010

I've been trying to figure out a simple keypress handling event.I have the code working fine after hunting for a couple of days on the net but have a problem getting rid of the obnoxious bong that comes along with hitting the ENTER key.I've attempted some solutions on the web about changing the KeyAscii to 0 but under that method I cannot even get the program to recognize the key is even being pressed.The code I have so far is as follows and I'm just trying to get rid of the audible bong.

VS 2010 How To Retrieve That A Button Is Pressed In A Existing Program

Oct 28, 2010

i have a program called Vip Task Manager.This program lets me set up task which others have to complete.When they are done with a task they have to mark it "completed" and make a report on what they have done and used to perform this task.Vip Task Manager has a button which directs them to an upload form, now when they press the "open" button I would like this to happen: Open a certain report making program I made myself.When they finished writing their report and press save, the program saves this report on a dedicated network HDD (.txt file) and closes itself.Then add the file or link to the upload form in Vip Task Manager.What it all comes down to is that they dont have to minimize Vip task manager, open the report making software, save it, go to vip task manager, press upload, press open, look where this file is saved, select it, and upload it.now, typed in red is whats already been taken care of.The rest, I have no idea where to begin to be honest.First I want to find out how to retrieve that a button is pressed in a existing program. (dont know which code it is written in and it is not open source)

Check If A Key Is Currently Pressed?

Feb 4, 2010

How would I check if a key is currently being pressed?

Also how would I detect if a key is pressed without using the KeyDown event. The reason I am not using the keydown event is when the user holds down a key it calls the event, waits a second than keeps calling it. I do not want the wait period if a user is holding down a key.

Get A Key Pressed From The Keyboard?

Nov 7, 2010

This may sound like a dumb question but I need to know. I know you can tell which keys are pressed on the keyboard but I like to know if I can do something.Ok, heres what I am trying to do. A user is in another program that is max on the screen. He has to press Print Screen to take a screenshot, but he got to min the screen he is in to paste the screenshot into paint. This causes slow loads on maxing that screen and sometimes crashs of the program. I already got the code done to check when the program is running and to capture the screenshot and save it. What I to do now is, find out while in the other program with my program running in the background, if the user has pushed the Print Screen button.

Asp.net - Detect F5 Being Pressed And Refresh?

May 25, 2009

I have a webform and i want to detect if F5 button was pressed or if the page was refreshed. I know about postback but it is not what i'm looking for. I have a gridview that loads in a modal popup when a button is clicked and a parameter's value is set for the gridview. When refresh is hit and if the modal popup button was previously clicked the modal popup is visible right after refresh. I want to detect if the page is refreshed to prevent this. any ideas? I thought to try Override but I'm not exactly sure how to use it. I tried Control.ModifierKeys but I don't have access to ModifierKeys.

Detecting If CTRL+ALT+DEL (or) ALT+F4 Is Pressed?

May 15, 2009

I know that you cannot disable Ctrl Alt Del for security reasons. I was able to figure out how to disable ALT+F4 in my application though. What I am wanting to know is if anyone can give me some code to where If CTRL ALT DEL is pressed then my application will close. I have tried everything, and I just cannot seem to get the program to recognize if the user presses ctrl alt delete.

So basically I need some code that detects if a user presses ctrl alt delete then if htye did it closes the application.

(I am making a quiz program.)

PS: I am on Windows 7 RC and I also use Windows Vista. I am using Visual Studio 2008 Professional Edition.
