View 1 RepliesI am creating a program for which will calculate the time taken for a user to make a number keystrokes. I want to start the timer running from the beginning of the first key stroke and end on the final keystroke. Each keystroke has been linked to a label which will change colour according to whether the key has been pressed. When the keystrokes have been finished I want to save this timespan in a field in a database. To test that the timer is running I have made a messagebox which will show the time taken however it is constantly showing zero and the label for the final keystroke is remaining in the keydown colour.
Public Class Form1
Dim dteStart, dteFinish As Date
Dim span As TimeSpan

I am practically a beginner at Visual Basic, and programming in general. I have created a simple falling bricks game in Visual Studio 2010. Every 100 milliseconds, it scrolls down bricks and if the player's position hits a brick, the player loses. I am having trouble with input.
I do not know how to make the computer accept left/right arrow keys as input, without having to wait for an input every 100 milliseconds. Here is the code:
Imports System.Threading
Module Module1
Dim RandomN As New Random

I have a ERP system which create a PDF file and write it to the disk when the invoice is beeing created. On the other side a have an .NET app, which every 10 minutes read data in that folder and automatically send an e-mail to my customer with the invoice attached.The problem is that sometimes, when .NET app try to read a file which currently is beeing created -> The file is damaged. How to avoid such a situation? Is there a way to e.g. read only file creation time, and if it's "younger" than 5 seconds order app to wait a while?

View 2 RepliesI'm trying to capture 4 keystrokes from the user and store them in an array. Once the 4 keystrokes have been entered, I would like to make it so the user can no longer enter anything, or at least have it show up on the screen.
Here's the logic I have so far:
For count As Integer = 0 To 3
Select Case e.KeyCode
Case Keys.D1
recOrder(count) = 1
[Code]...
What I wanted this code to do was to count the number of key presses and what keys were pressed, and compare that array to a predetermined array.Edit: I forgot to mention that even though the array has been filled with key presses, when the user hits a key, the screen still updates. Also, this code is in a Keydown event.
I have used CSV files before for a simple database of about 12,000 items - this was a simple one page form... Now I want to have the same database but with the data available to multiple forms at the same time.. eg.. Form 1 displaying persons 1,2,3,5,7 name, addy, phone etc and form 2 pulling info for persons 2,3,4,8... Is this possible with CSV files?? or even XML?... The only other thing is that I do it all in .NET 2.0....

So I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
View 12 RepliesI have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
I need to be able to move it up with the up arrow key, down with the down arrow key, left with the left arrow key, and right with the right arrow key.I know my "Player" works by the way:
Private Sub PlayerPic_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayerPic.Click
MsgBox("test")

I'm using VS 2008 and .NET 3.5. I'm in one of my programs and when I run the program to test it, I keep getting these errors... 'Exception occurred' And the line is highlighted green and there's a green arrow on the side line (where you can enter breakpoints). When the code stops at these exceptions, I can hit continue and the code still runs just fine even though there were a ton of exceptions. Now, I'm wondering if there is a way that I can skip over these or have them not show up because I know the files that this is happening have not been changed in several weeks and I've tested this program beginning of this week and it was working fine... no exceptions or anything. I'm not sure what would've changed. The only thing I did was install the newest versions of Telerik Rad Controls. That should have nothing to do with the exceptions I'm getting.why i'm getting these now all of a sudden or how I can just skip over these without having to hit continue after each time?

I have made a really simple program launcher for my home theater pc that allows me to launch 6 programs, open/close the optical drive and shutdown.I don't have a mouse or a keyboard normally hooked up. I can navigate the buttons with the up and down arrows fine, but only in the tab index order. Is there a way to allow the left/right arrows to focus on the buttons to the side? Here is a screen shot of my application to hopefully give a better idea of what I'm asking. (eg. Can I hit the right arrow from my first button and focus on the Open button?)
View 4 RepliesI have a group of radio buttons inside a groupbox and I don't want the user to be able to move the focus away from a button by using the arrow keys. I've tried the following keydown event, but it never gets fired:

' If an arrow key is pressed, maintain focus on this radio button
