VS 2008 Only Allow Certain Number Of Keystrokes?
Apr 20, 2010
I'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 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 have seen that there are many "Mouse & Keyboard Macros/Recorders" out there & I was wondering how they are being created in visual basic. I have looked within the Microsoft forums, but havent really seen any specific coding that works for the kind of recorder that I'm trying to create.

I am trying to send some keys to a program that I launched, but every time i send the keys focus is not on the program and the keys are sent to the wrong program. Is there a better way to send keys to a program or a way to set focus on a certain program?

I'm trying to create an application similar to the site WhatPulse, which will generate an image with my clicks and keystrokes. WhatPulse only updates the image once every 24 hours, so I am going to make an application to keep track of that for me, only with realtime stats.
How can I count total keystrokes (outside of the application itself) as well as total clicks, in vb.net?

I am facing a problem in my code. I am working on an application in vb.net, its a windows based application. On one of my form I need to perform so many data driven operations.
if I press tab on one of the text box, I need to set a computed value in other text box and need to set the focus to that text box.
I write a code that is a like to this.
Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
Select Case e.KeyCode

I am using visual basic code, specifically the sendkeys.send method, to send keystrokes to a different application, in my case Acrobat Reader. Here is my problem. I am sending instructions and text to define a path to a file I want to open in Acrobat Reader. Every keystroke is being sent and interpreted in Reader correctly except the Colon. This is the line of code I am using:Sendkeys.send("C:")
I have tried every variation of this simple line of code I can think of, but the result is the same. Reader for some reason wants to interpret the Colon as Uppercase Q, so what I get is CQ. This of course totally messes up my path to the file I want to open.Sendkeys. sendwait("C:") Behaves the same
I understand there are timing issus with this method so I have added code to my app.config file suggested in this forum for taking care of the timing issue. I have also inserted delays into the execution of the program steps. Nothing I have done solves this problem.I wonder if anyone else has experienced this or a similar problem and if so what was done to correct it.

I'm trying to do some interface for a game for people with mobility probs, like Parkinson, so grouping several game features in just one control.Everything goes fine but having problems sending keystrokes to the game window when they have modifiers.Lets say I want to send Alt+F1 keys, according all the search I have done, the code is:My.Computer.Keyboard.SendKeys("%{F1}")but it does just like I sent an F1 Keystroke: My.Computer.Keyboard.SendKeys("{F1}").I need to send Function Keys alone and too with Alt and Ctrl modifiers, but not success with modifiers, the game only gets like an alone function Key was pressed.

My form contains a Button and a Flash Control. The Flash Control contains a game referenced to a website. I want to send keystrokes into that control (the game) without having to be in focus. I'm not experienced in flash so when I decompiled the game, I had no idea how to script a way for it to work programatically.

How do I make the form send keystrokes such as Tab, Enter, Left Arrow etc to itself without interfering with other programs? If I use the SendKeys.Send method, it would send it to whatever window is opened. Is there a way to only work with the form? Very quick random example: Let's say I have 5 textBoxs and I click the 'Tab' button 5 times. What would happen ?
It would change the focus from one textbox to another right? Can I make this happen automatically ... like make it happen in the background and only to the form itself. So If I'm typing something on Notepad, I don't want to receive those 5 tabs. By the way I know I can use this code to change the fofucs, but remember its only an example.

I have a fairly large project (Point of Sales) written in VB6. It has beenused successfully a 2 stores since 2001 (with updates of course).I would like to convert it to VB2008 (although I know about VB "fusion") just to keep it up to date and modernize it a bit.Since using the VB converter brings up such a lot of junk, I'm rewriting each module and form from scratch (although using as much of the original code as possible). One of the functions I'd like to retain is typing in a textbox, and converting each keystroke to upper case as it is typed.Here's the code I use in the VB6 version:
Private Sub txtDescription_KeyPress(KeyAscii As Integer)
Call EnterToTab(KeyAscii)

I have built many applications that work with a barcode reader. What I need now is a means to reading the scanned item through a background services such as a windows services or something.My task is to scan a barcode on a identification label that is placed on a cut size of glass and record the order line item as being processed. This will update the database to reflect the cut size has been completed.My restriction is the processes keeps an application showing a cut pattern of the stock sheet of glass in focus so I can not have another application active to capture the scanners results. Here in lies where I have to have a application running in the background listening for a text or alpha-numeric string that will tell the application to run the scan.

I like to automate this 2 clicks with a keystroke. I dont see any mouse button click keystrokes.

I was trying to make a program which displays two chars A and B on the screen. Using the WASD keys, it lets you move the A char around and using the arrow keys it lets you move the B char around.
I wrote the following:
Module Module1
Dim Box_A(1), Box_B(1) As Byte
Dim Allow_Draw As Boolean
[Code].....
When I run the program, if I press any of the WASD or arrow keys the corresponding char doesn't move. To make it move, I have to hold down any of its keys for a bit after which I can move the char just by pressing its keys. But then, I have to do the same for the other char.
So, if I want to move B I have to hold any of the arrow keys for a bit. Then I can easily move B just by pressing any arrow key once. Then to move A I have to hold any of the WASD keys for a bit and then I can move A just by pressing any WASD key once.
Is there any way I make make each of the char move just by pressing its ket once?

I'm trying to send the keys "ABC" and "Enter" to Notepad when I press a button. I've been reading forever on Hooks, "SendKeys" functions, but I can't figure it out. I don't think I need to use a hook, because I'm not making a hotkey or anything, I'm just pressing a button and sending the keystrokes to a window when it's not focused.

But its like chinese for me.my goal is to run these little programs by the 100's on 1 pc. and they just press a key in their own application , over and over.i was thinking something like this
Private Declare Function PostMessage Lib "user32.dll" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Const WM_CHAR As Long = &H102
