Using Keydown Commands In 2008?
Apr 8, 2009
I am extremely new to visual basic and it is the first time i have ever tried to program anything. I am currently using Visual Basic 2008 Express Edition which I downloaded for free off of the mictosoft website. Anyhow, to the question at hand: I was wondering how one would use keydown commands in VB express 2008. I have looked far and wide and have yet to find an answer to this. To simplify it to a specifit answer how would I move (or rather, slide), say, a picturebox to the left of the screen by holding down the left arrow key and have the picturebox stop moving after I released the arrow key. By simply seeing how the code is I should be able to do it for any other keydowns.

Well I'm currently in the middle of adding a few fine details to a program I'm busy with. Basically whats happening though is that I want to be able to delete some settings on the fly instead of individually, I also want to accomplish this through a simple key press.
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.F1 Then
MsgBox("Do you wish to remove all entries and clear all relative data?", MsgBoxStyle.YesNoCancel)
If MsgBoxResult.Yes Then

I'm currently experimenting with a tile based dungeon crawler type game. When the WASD keys are pressed it will move in that direction, however if the key is held down it will move incredibly fast over the tiles, which is not what I want.Instead I want the player only to be able to move one tile at a time, or after each key press. Is there any way to do this with the KeyDown event or do I have to use KeyPress to make sure it only activates after each full key down & up?

So I'm working on my webbrowser, and just managed to get the ol' tabs working for it, but how would I go about adding a shortcut like "CTRL + T"
I tried this:
Private Sub TabControl1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TabControl1.KeyDown

counter1 += 1
End Sub
I set TextBox3 max length to 8.What code should i write if i want it to be like this:I wan the counter1 to stop increasing if the TextBox3 reaches 8 characters. (Even there's still key down occurs)After I click a button, the counter1 is able to increase again.

i recently took a look at a game i tried to put together, and decided i wanted to finish it.The game is a shooter game that creates 'walls' that the player should not be able to move into. These walls are panels, and currently, im using one keydown event to move both players. This is not a good thing, because it makes it impossible for both players to shoot and move at the same time. The player should not be able to run through the walls

I try to catch the keydown event, but arrow keys don't fire this event, although I set KeyPreview = True. Arrow keys neither fire the KeyUp event. Not on the form or on any controls..
What is required to handle:
1. Arrow keydown or keyUp event with individual event handler based on mouse focus/hover (does the control have focus if mouse hovers on it, or it needs to be clicked?)
2. Mouse scroll events individually based on "mouse focus"
I don't actually need for the form... Since all the form is covered by controls.. But I need individually for different controls. Which are just buttons, labels and a chart control.

I have the following code which I use in another Form and it works perfectly. I copied the same code to another form, changed the controls, keys combinations, etc., but the keyboard shortcuts do nothing at runtime. None of the key combinations work, it throws no Exceptions,I put a MessageBox in the F1 KeyDown conditional, but it doesn't show. That tells me that it's not Handling the KeyDown Event.[code]

I am trying to use the keydown/keyup events with buttons in the same project and it not working properly. I have 4 red boxes and when I press an arrow key the box should change to green according to which arrow key it corrosponds to. I have this part working fine, however only when there is nothing else in the project. When I add in say 3 buttons, Button1, Button2, Button3 and try runing the program instead of the correct red box changing to green, button outline just moves between buttons 1,2 and 3. I have tried turning tabstop off for the three buttons but that didnt work. how to read the keydown/keyup while still having buttions that can be pressed with a mouse?

What I need to be able to do is send a command across a specific network port (eg. 2124) to a specific ip address. I already have writen the recieving code (for the iPhone os) and accepts commands like:
filefound("Name of file",filetype,size)
All this is to be sent in plain text and once received the iPhone will then send a command like:
nextfile()

I have a very large table, and I have a sql data adapter to fill a data table. The user is able to change some values, then saves the changes, at this point i just call the adapter update method (I use the sql command builder to get all the commands of the adapter). What I need it's to make some changes to 4 parameters in the update command, before calling the update command, but I don't see how to do this? Before the update itself, I don't have any values, if I set the parameters (I saw the number of the parameters in the debug mode), before the update, that doesn't do anything, I think they get override in the update method...

I have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
acccmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
then the other command :
intcmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?

i have a problem: I have a Form_Load-Method which is not doing all the commands in it. It just interrupts and jumps to the "Form_Paint"-Event, eventhough i did not yet paint anything or invalidated any object. The Form_Load-Method is this:
[Code]...
the dashed line indicates the point of termination. the for-loop is simply not done. i tried it with stop points and the last point it stops is the ReDim-part. this can only mean, that the ReDim-Command forces the program to leave the method. but the for loop is never done afterwards. Can you help me? Because i really dont get it.

i have been looking everywhere for the method used when you click the [X] Button so like that i can run some commands on form exit. I found Form_Unload method replacing Form with the name of my form and no luck. I'm sure there has been some talk on the subject but searching forum shows nothing that seems to work.

I'm trying to create a program that does the following:Executes the following command line string (wmic /node:computername bios get serialnumber)Prompts user for the "node" entry Displays the resulting serial number in a dialog box I'm a bit of a noob at this (I haven't coded anything in VB since early 2000s) so I'm at a bit of a loss where to start. I plan on including some functions to submit the node entry and the resulting serial number to a database in the future for archiving as well.

Basically, for my first VB project, I am creating a virtual keyboard where a sound is played from the resources on KeyDown. So far, the program seems to work except for the fact that each key needs to be clicked by the mouse before the sound is played by pressing each key (hence put the object in focus), where I need the key to play the sound without clicking the keyboard key (put the object in focus on KeyDown). Below is an example of my code:
Private Sub C_KeyDown(ByVal sender As System.Object, ByVal e As PreviewKeyDownEventArgs) Handles C.PreviewKeyDown ' C is the label attached to the first 'Rectangle' (Key)
If (e.KeyCode = Keys.A) Then 'The A key should activate the C key on the keyboard
[code]....
I have KeyPreview set to 'True' under the form's properties.

PictureBox2.Focus()

When I debug and click space down, my picture box of the knob slides on down to 175, pauses, and shoots back up. The problem I'm running into, is that it doesn't do anything if I try to pull the knob down again. It doesn't bug out or anything, but it just doesn't do it again
