Hi,
I have a text control on a form which is bound to table field StartDate
which is in Date format. When updating the table record via the form, any
data entered into the StartDate control is immediately validated. If the
data entered is considered valid, focus moves to the next control in the tab
sequence. So far, so good.
If the data entered in StartDate is considered invalid, an error message is
displayed via MsgBox. When OK is...

I am still trying to get the Undo function work on Internet Explorer editor
hosted as activex in my c# application.
Some time ago I've found a note at msdn that says "undo is not supported". I
gave up.
But lately I've downloaded LutzRoeder Writer that makes use of undo
function. I've looked at the code and it turns out that it uses
IOleCommandTarget interface to invoke this command.

Hello,
I've tried to find information about how to implement an Undo/Redo pattern.
This article describes such a pattern:
http://www.codeproject.com/csharp/PcObjectUndo.asp , but is a little bit to
narrow, since it only can handle 1 object, and since it only works on
properties.
What if you , in an application, have more than 1 object , and you want to
use undo/redo on them?

Dear ladies and gents,
I'm trying to determine whether the .NET Framework implements a means
of transactional processing without the need for a database.
Essentially, I'd like to enlist light-weight portable business objects
within transactions so that that have the ability to roll-back if the
client of the object wishes to undo any changes made. For example, if I
had a, let's say for sake of simplicity, a person class that had two...

I have created my own context menu. Everything works except undo'ing
deleted text. My code for these two events are:
Private Sub tsmiUndo_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles tsmiUndo.Click
' Undo the last thing the user did and clear the undo buffer to make
sure that clicking
' Undo again doesn't redo the last thing undone.

Hello,
Does vb2005 have a built-in UnDo feature / object for applications so that I
can undo actions like other windows apps? Or do I have to write my own UnDo

If vb2005 does have a builtin Undo feature / object / command -- how to

Hi all,
I'm extending an Abstract Styled Document associated with a JTextPanel to
implement a syntax highlighting editor. This is all working just fine -
except for undo / redo.
The problem is that the undo manager is recording my highlighting that
occurs as a result of keystrokes. So whenever the user performs undo, the
last operation (a colour highlight operation) is undone. Since I need to
refresh the highlighting when the undo is...

I'm working on an application that does some DOM manipulation. I want
to add a mechanism for "Undo" so that the user can revert to the
previous state after performing a mistaken action. Simple idea, not
necessarily simple to implement.
My first idea for this is to use closures and an array that tracks the
inverse of the user's actions. Here's a simple example in which the
user can only remove DOM nodes and then undo the removal...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
