I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

Winforms, VS2008 I have a mainform that has 2 usercontrols: UC1 and UC2.UC1 has a treeview with treenodes. UC2 has tabControl with few tabPages. Selecting different nodes displays different details view in the TabControl's TabPages. What I need is canceling the event when the user has selected a node in the treeview, then he selects another node (i want to be able to cancel this last event:selecting another node, all depending on a certain logic)I mean: When the user is working on a tabpage in the tabControl, when he clicks on a different node in treeview (different from the currently selected node), before displaying the new node's details in the TabControl, I perform some logic, then depending on that logic, I set
e.cancel = true in the UC2 Validating event handler. (Rememebr UC2 includes the TabControl and the user, supposedly, has the focus on a control somewhere in TabControl)
But mysteriously, the event gets never canceled and the user still moves to the next node, displaying its details in the TabControl, although I set e.cancel = true.
i want to do this: when user click save button, the form must be check first..

KeyAscii = 0
End If

How do I add a cancel button to a message box? I really need to know this because it is kinda stupid that i have a message box saying "Are you sure you want to clear everything?" and have no cancel button. Also what code do i need to make a program key where it is made so that I give a key and it works with that specific program another one will be made with a different key. I have no code for that because i have no clue where to begin (3 day trial code so it is locked would be nice to) The other problem I have is makeing the program open new windows so if i click trial then it will run for 3 days then done and with code making it run forever without the pop up again so how do I do all that?

I have a simple windows application that pops up an input box for users to enter in a date to do searches.
How do I identify if the user clicked on the Cancel button, or merely pressed OK without entering any data as both appear to return the same value? I have found some examples of handling this in VB 6 but none of them really function in the .NET world.
Ideally I would like to know how to handle the empty OK and the Cancel seperately, but I would be totally ok with just a good way to handle the cancel.
I have an ASP.NET form with a cancel button that is supposed to, after confirmation from the user, redirect them to another page. I'm using javascript for this. It works fine in a simple HTML page, but apparently something is interfering with it on the .aspx page. The popup message works perfectly, but clicking "Okay" does not take you to another page. I have tested the if statement and it is working correctly, the only thing it won't do is leave the current page. [code]...
View 1 RepliesWith my Application (vb.net) I am trying to scan Excel files some of which have ActiveX Components.
When running my Application, I am getting a pup-up window in Windows Vista Environment with Office-2007 having button OK and Cancel button to proceed.
But my problem is the scanning is not proceeding even after I keep on pressing the OK button. Now I want to continue with my application while pressing the Cancel button; i.e. just to skip the file. Is it possible to capture the response from the cancel button? (As this is a message box from another application, i.e. either from Vista or Office-2007, I'm not sure).
I have a login form (startup form) with OK/Cancel button, and each set on the form as Accept/Cancel button - works fine.
After login my main form loads, it has keypreview on. This main form opens a new form (after user clicks a client search button) with an OK/Cancel set up the same as the login form.
On this search form, the Enter key works (it calls the OKbutton click just fine), but the Esc key does not.
The cancelbutton property if set to the cancel button, and this form does not use keypreview.
The form has focus, I clicked it to be sure, but in any case the enter key works.
I need to hide the CANCEL button in the VB.NET control WinProgressDialog(VB.NET 2005) How do I do that?The requirement is that the dialogbox should continue till the time the process is complete.
