the problem at dg_KeyUp code, Since more than 1 row created while I want only 1 line only.
I have focus on button and when I press Enter key button_click event is executed. At the end of button_click I pass focus to text filed:

And every time I press Enter on button txtNewItemID_KeyUp is triggered. And i don't want that. I just want txt field to get focus when button is pressed (with mouse, enter key, Alt+key combination).
I'm trying to create a shortcut which expands or collapses my treeview using the ctrl+alt+up-arrow or ctrl+alt+down-arrow:

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:

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

whats the simplest way to achieve this? is there a built in value for this or regular expressions?
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.
There a way to use e.Cancel () on a keyup event?
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

I am needing to call the KeyUp Event of my richtext box. Anyone know how I can do this?

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?

View 1 RepliesIn VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp
Now when I migrate to .NET I changed the KeyUp event to Private Sub textBox_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox.KeyUp
How can I do this call textBox_KeyUp(-1,0) now from textBox_MouseUp event?
I have a datagridview having 3 columns (qty,scraft factor,actuall qty). What I want is if the user encode 50 in qty and 2 in scraf factor, actuall qty will automatically computed based on qty multiply by 2. I was using keyup event. Now I am using endedit to get the current value of the current row and column, now the problem is if the amount to be encoded is more than one digit it will not accept because of endedit. What event do I have to used? or any solution with this scenario.
