Handling Keys.back In Richtextbox?
Mar 20, 2009
Because I'm handling my keydown on the form that basically complicate obvious thing. Now I have to manually program my keys.back on a richtextbox. However, the code below put my cursor back to the beginning of the textbox everytime I delete a char. Is there a way I can control my cursor to stay where it is?
Private Sub Form_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyValue = Keys.F1 Or Keys.F2 Or Keys.F3 Or Keys.F4 Or Keys.Escape Then
'call my other functions
[code]....

Basically I need to handle a keypress or keydown/keyup event on a form, specifically for the Up, Down, Left, Right arrows. Using the below, nothing moves. However, if I change (Keys.Left) to (Keys.A) then a capital A will move the object.
vbnet
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Left) Then
'Note that 'man' is a PictureBox.
man.Location = New Point(man.Location.X - 5, man.Location.Y)
End If
End Sub

i have a very short program that is basically mimicking the back, playpause and next functions for music (because my keyboard does not have buttons along top ), so i am using numpad. now, of-course, by using numpad, it's typing the number 2, so if i am running an application with a textbox it will type the number 2, so i want to delete this, but i do not know how.

I am trying to creat a program to automate many of the things I do when I build a computer. I was attempting to do this via batch files but got stuck when I needed to search the registry for cetain keys and delete the parrent folder in which it resides in.
For instance: Installing a MS Loop Back Adapter I found a utility that works at the command promt called DEVCON that will allow me to install a MS Loop Back Adapter. I was doing this through a batch file but found that I can call the utility through VB and get the same result (of course I still need to have the DEVCON.exe)

I 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.

How could I loop through a list of the keys that are available in the 'Keys' enumeration? It seems like it should be something easy to do, but I'm not having any luck finding a collection that I can loop through.

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

We have a server application and a client application that communicates with each other using socket.
When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.
We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.

We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

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.

I need to capture the left and right arrow keys in Form1.KeyDown event so I can use them as hot keys. Instead they seem to be assigned to tab order (move focus to previous/next control) and the KeyDown event never gets called. How can I remove the arrow keys from tab order and use them for my hot keys instead?

I am creating an application that will be faced with multiple decisions to make and I want to know if it is possible to create around 20 if statements to excute or decide between before excuting?
The application will encounter multiple websites but each website will have the same elements but not neccessary in the same order so I was going to tell the app to loop through the IF statement and if the condition is met to run that sub routine where it starts over and loops through the IF statements until next condition is met.
Is this possible in VB.NET or is 20 or so IF statements to many to use at once?[code]...

I tried a couple of the send keys and they will not send any keys at all. I need a true Space bar input (SendKeys does not work for me). Also, I would like this to work on 32 and 64 bit computers. Let me know if you know of any good examples. I would love to have the ability to send a string in the future, but I can add that feature myself. [code]
