How To Hook Up Keypress Events For Cut / Copy And Paste Routines
Nov 5, 2009
I have a Windows Forms app, with a TabControl. On the first tab (which is a bunch of textboxes), the CTRL-x/c/v keyboard shortcuts for cut/copy/paste work as expected. On the second tab (which is a DataGridView), the keyboard shortcuts don't do anything. How do I hook up these keypress events to my cut/copy/paste routines? I already have great cut/copy/paste routines for my DataGridView--and they work fine when launched from the tooltip buttons or menus. I just need to hook up those subs to the CTRL-x/c/v keypress events.

I have a text box called TxtSearch on my form. The value entered should always be numeric before the search can be done if its any other data type the following Message box is give - Only a numeric value is allowed in this field", MsgBoxStyle.Information, "GCPM.. (Code shown below)
Private Sub TxtSearch_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TxtSearch.KeyPress
If Char.IsDigit(e.KeyChar) = False And Char.IsControl(e.KeyChar) = False Then[code].....
Now, when you copy and paste a String value on the textbox - TxtSearch the KeyPress doesn't work. The TxtSearch doesn't prompt the message and when you click the Search Button the application crashes - dsiplaying an error converting data type varchar to numeric.. What I want to do is if someone uses the copy and paste tool to enter the value in the textbox- TXTSearch and there is a datatype not numeric the message prompt is called ..

I have a small copy/paste type of program. You put text in the boxes, click copy and it copies it to the clipboard. I have a text file attached to format the text when it is copied. what I want to accomplish is...If I don't fill in every single textbox with text, I don't want that particular field to show when I paste it. Example, I have the layout like below on the text document.
textbox1.
textbox2.
textbox3.
No matter what, when I click copy, the text document is going to copy textbox1,2,and 3. If I only put text in textbox 1 and 3, I don't want it to copy textbox2 if its empty.

I'm using a textbox to define a hotkey, and I need to make the textbox receive key events and prevent the form from receiving them.The reason it's a problem is because Tab (and probably other keys) is a valid key, but the form uses that as a shortcut, so the textbox never receives the keypress.

I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part.
I am using the (I assume pretty widely used) following code for Global Hooking of the mouse.

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.
How can I get it to fire the form1 sub routine on the close event of form2

I am trying to modifying the "Math Quiz" tutorial to be more user friendly.
The initial tutorial does not consider the users efforts to answer the math problems as quickly as possible.
The problem is that you must use the mouse or tab key rather than the "enter" key to move to the next control after answering. I believe using the "Enter key to be much more intuitive.
Therefore, I wish to modify the program to either:
1. Check the KeyPress event of the NumberUpDown controls to watch for the "Enter" key to be pressed, and if it is, check to ensure that the current NumberUpDown control is not empty (= Nothing) and if both are True, to then TAB to the next control in the TAB order; OR
2. Uses the PreviewKeyDown event to transpose the "Enter" into a "Tab" automatically so the application will then TAB to the next control in the TAB order.
With all of the new changes to VB 2010 from the last version I actually used professionally (VB6), things are REALLY different, so I no longer know how to accomplish this same task in the new manner. especially if it contains working CODE, because I have always learned better the first time from an example. here is my version of the tutorial Code:
'--- Create a Random object to generate random numbers.
Private objRandomValue As New Random
'--- The Integers will store the numbers for the
' addition problem.

is it possible to create a class which has the majority of your keypress controls? Like allowing just letters or numbers in a textbox etc. To make things clearer what i exactly want. I have a textbox on my form. This is a textbox for the postcode. The postcode is supposed be something along the lines of AA 1234. This will be checked on lostfocus.

In the application I'm working on I use F1 and also a right mouse click to close the application since the graphics display full screen and there's no control in the upper right corner to close with. I use a good number of different keypresses to control things and everything works fine. When I switch away from the form that the applications starts in to a different form I'm not getting any response from either a KeyDown or a KeyPress event. Maybe someone knows what's going on. The ButtonClick and MouseDown events are responding just fine but for some reason the KeyDown and KeyPress events aren't. Below is code for one of the Forms that is unresponsive in this way.

I know you can validate textbox text by using the keypress events. But the form i'm working on has multiple groupboxes with multiple textboxes. So rather than having a sub routine to validate every groupbox, i was wanting to have just the one keypress event that handles the textbox entries, and depending on the textbox calls a specific validation routine.[code]

I am new to VB but I want to find this out. For example there are two objects in my form and when I press W,A,S,D then Object1 should move Up, Left, Down and Right respectively. Object2 moves when I press the arrow keys. How do I make them move together and also separately depending on whether the key is pressed.

I have a TextBox which Is allowed only to read certain characters. I use KeyPress event to handle this event. I understand that The KeyPress event does not handle the pressing of the DELETE key on the keyboard. I do not want the user to be able to delete characters in the txtbox by using the DELETE key, I want the user only to be able to use the backspace key. I am writing this code in Visual Basic 2005. The following code appears to work in handling the DELETE key, but I am concerned that I might get bitten by the fact that I am using KeyDown and KeyPress on the same control (txtSource).
private sub txtSource_KeyDown(byval sender as object, byval e as KeyEventArgs) handles txtSource.KeyDown
IF e.KeyData = System.Windows.Forms.Keys.Delete then
e.handled=true
end if
end sub

Looked up a number of pages on KeyDown, and KeyPress events, and am just more confused than when I started. I am trying to get an event to fire adding value to a total when a user presses the Enter key. Not getting any compiler errors, and have tried utilizina MSDN's suggestions for IsInput, and PreviewKeydown. None are working..... I have tried working in the KeyDown using e.keyCode = Keys.Enter, and KeyPress using e.keyChar.Equals(Keys.Enter) in my conditionals.

Function IsInputKey(ByVal

In my Sheet1, i will be having a data From column A to F and in Colunm D (The Red one) it will be empty, The data can be 10 rows or might be more the 60 rows sometimes and in Column I i will have some more Data.

Exm: IF i have 50 lines in Column F and in Column I i have 5 lines Then i should get the result of (50x5=250 lines) 250 lines each of 50 as per Column I.

I have a datagridview and I would like to be able to select an entire row by clicking on the row header column, hit CTRL+C, then put the cursor in the next row, and hit CTRL+V to paste the contents.
Right now, it pastes all of the contents into the first cell of the new row. If I paste the contents to the clipboard, I see them correctly and they are tab delimited.
Once I get this working. I would like to be able to copy and past multiple rows at a time.
FYI, I am not using a data source at all. Most of the rows are combo boxes where a user is selecting values. There is no database connection.

I have an problem with copy and paste between 2 richtextboxes part of the problem is if I new the 2nd Richtextbox actual name I could paste it using rtf format because I have so many of them I use a loop to go through the controls until I find the right one using typeOf control. The problem is with that that it really doesn't act as a richtextbox. See code below.
Dim RTB As New RichTextBox
RTB.Name = sender.Tag
For Each itm As Control In EnumerateAllControls(Me)
