Get Keyup To Recognize A TAB Key?
Jun 19, 2009
I have an data application I made for a company. I want them to be able to hit both the Tab and the Enter key to select the next control in the tab order. I would also like to turn the background of the currently selected control a color other then white. I have been trying for days to find a solution but trying to interpret the msdn library is making my head spin..For some reason, the below code only recognized the enter keyup and not the TAB key.My Code here:
Imports System.Windows.Forms
Public Class Form1
Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As

Currently I am able to see if a key is currently pressed via the GetAsyncKeyState function. Currently I just simply have a timer running in the background that constantly checks if a certain key is pressed in order to run a command. However my issue is if the user holds down the key it will continually run that bit of code over and over per timer tick. Is there a way or another function to detect a keyup or keypress only. This is my current code to detect keys:
Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Windows.Forms.Keys) As Integer Public ReadOnly Property CurrKey(ByVal key As Windows.Forms.Keys) As Boolean
Get Return CBool(GetAsyncKeyState(key))
End Get
End Property

I am working on an application using a form with textbox controls as a menu. Pressing enter while the textbox has focus invokes another form and hides the menu form. The reason for this is a requirement that the mouse must not function at all in thisapplication. Not my idea but it is my job to make it so.The problem I could use some. When the user presses enter on the textbox on the menu form the keypress event is used to invoke the selected data entry form and the menu form is hidden. When the data entry form opens the cursor is supposedto be in the first field on the form but the first controls keyup event triggers and the enter keypress from the menu form is still active so the cursor moves to the second control on the form. Having the enter key move to the next field like tab does is also a requirement.
In the keypress of the textbox on the menu form e.handled is set to True but that does not prevent the passthrough. I realize there are many ways to force this to work as I intend by putting flags and so on in the data entry form but I have many to deal with and would like to find a solution I can apply on the menu form rather then adding code to every data entry form to compensate for .NET deficiencies.

I'm trying to validate a textbox with a Regex and I need to cancel the event if it no meets the Regex expression, or delete the key pressed to meet so that the expression
For Example:
Dim rex As Regex = New Regex("^[0-9]{0,9}(.[0-9]{0,2})?$")

I have this code
If e.KeyCode = Keys.D0 Or e.KeyCode = Keys.D1 Or e.KeyCode = Keys.D2 Or e.KeyCode = Keys.D3 Or e.KeyCode = Keys.D4 Or e.KeyCode = Keys.D5 Or e.KeyCode = Keys.D6 Or e.KeyCode = Keys.D7 Or e.KeyCode = Keys.D8 Or e.KeyCode = Keys.D9 Or e.KeyCode = Keys.Oemplus Then
[Code]....
The output WILL be 189 when I press the - sign. But when I check "Keys.OemMinus" it stands for 189 and when I replace "Keys.OemMinus" with 189 it won't work either!
I checked the Resources file and it's correct. The picture just doesnt change, only shows the last pressed button...

I have a VB.NET application. When Texter or PhraseExpress is installed and enabled, the program behaves poorly. Debugging has revealed that at times I can press Enter in a field and no event will be fired (i.e. no breakpoints in the event handlers get hit), then I press it again, and they will be fired twice. (Basically these cycle if I keep pressing enter - one time nothing will happen, the next I get two events, the next keypress does nothing, the next triggers two events, etc.)
Since Enter is used in certain places to trigger searches, or to move between fields for fast data entry using the numeric keypad, this effectively breaks the program in these spots. The problem is highly repeatable - disabling Texter or PhraseExpress causes the program behaves perfectly normally. Enabling them again causes it to break. Note that in both text expansion programs, I have assigned NO events to the Enter key. In fact, with Texter (haven't done this particular test with PE yet), it happens even if NO replacements have been defined at all, simply based on whether Texter is enable or disabled.

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?

How do I make my program know that time is passing and interact with it? Currently I'm trying to use a method like this:
Imports System.Globalization
Private Sub CurrentTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentTime.Tick
Dim date_info As DateTimeFormatInfo = _
CultureInfo.CurrentCulture.DateTimeFormat()
ToolStripLabel1.Text = Now.ToString(date_info.ShortTimePattern)
End Sub
That sets the current time to ToolStripLabel1.Text it looks like: 10:25 PM. Then I made another timer, realizing I couldn't interact with Toolstriplabel1.text because the time contains " : and PM", and this timer does this:
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
TextBox48.Text = Val(ToolStripLabel1.Text)
End Sub
Basically it takes the value of toolstriplabel1 which would be "10" it gives a variable 1-12 in accordance with the current time. Then I have another timer that handles the main process, and in My.settings I have a variable:
My.settings.12hourspassed
So I was going to use My.settings.12hourspassed as a variable such as My.settings.12hourspassed = My.settings.12hourspassed + 1 - whenever the time (textbox48.text) goes to 12.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
If Val(TextBox48.Text) = 12 Then My.settings.12hourspassed = My.settings.12hourspassed + 1
If Val(TextBox48.Text) = 12 Then TextBox48.Text = "1"
End Sub
The problem is that I cant do textbox48.text = "1" because another timer is making it the value of the current time.. So whenever textbox48.text = 12 it constantly does: My.settings.12hourspassed = My.settings.12hourspassed + 1...
I know that this method completely skips an hour and such.. accuracy isnt all that huge. Any way to tick off whenever 12 hours have passed? and if the program is turned off a way to compare the current date with the date the program turned off at to see how much time has passed while the program is off?

I need to create a program, and now I want some advice from you, as I simply don't have so much experience to get round it.Firstly, I have issue with a checked list box. For example, there will be 5 items.I want each item to have a different value, because it will be a things people will be buying, and so when someone clicks on item1, the value I assigned to it will be output into a label, so user will know how much that item costs. I know how to output it, label1.text = CheckedList Box1.SelectedIndex but how do I set for example for item1 value of 5000, for item2 3500 and etc? Secondly, I will have a page for users, where they will see history of their bought items. But what's the best way to store the price they paid, item they bought and date? It should be able display for each user their own bought item history.I hope you understand what I meant, as I'm quite new in programming so It was a bit hard for me to express what exactly I want. If you didn't understand something, or need more information please ask me. I hope someone will be able to help me, as I really have a bit of a struggle with it. At first I wanted to use plain .txt file to store and output into textboxes, but it wouldn't be aligned, look nice and etc. Then I thought about database, but how to recognize which item to display for each user and etc.

Do I need to set something with the cookies? Or how would firefox know that I am already logged on on another browser? all is in Visual Basic 2008.
