You might want to take a look at the grids CurrentCellDirtyStateChanged and CellValueChanged events. The CurrentCellDirtyStateChanged event triggers as soon as any change is made in a cell, although the actual new value of the cell is not "known" in that event. The CellValueChanged event triggers as soon as the user exits a modified cell, and the changed value of the cell is known in that event. I've done some crazy stuff in the past where I've programitically moved off a cell when the CurrentCellDirtyStateChanged event triggers, captured its new value via the CellValueChanged event, and then programtically returned to the cell. You can get the new value of the cell in the CellValueChanged event with code similar to the following:

Hello all,I'm facing problem with applying the MySql.Data.dll file in Reference of my VS 2003. When I try to add in,I saw a prompup and show this Error Message:
A reference to' C:\Documents and Setting\Visual Studio Projects\Test\MySql.Data.dll' could not be added. This is not a valid assembly or COM component. Only assemblies with extention 'dll' and COM components can be referenced. Please make sure that the file is accessible, and that it is a valid assembly or COM component.
Thanks everyone for reading,I found the problem and solution for my post here. Just to share with someone who need it in the future,the following are what I found:
VS .NET 2003 doesn't support MySql 5.0/5.1 .NET Connector. The only connector supported is 1.0 .NET Connector which is the most earliest version of tools build by MySql to linkup with VS.NET 2003.
Thanks for everyone effort and hope this helps you all there in the future.

I am writing a simple program in VB.net to use netsend to be able to send a message to all the users on the domain when I need to restart the server or other things like that. I have already turned windows messaging on on all of the computers, however, I can not figure out how to send the message on a button click in my program. It is a very simple windows form program with two text boxes called "CompOrDomainName" and "Message" and three buttons, "Send", "ClsButton", and "ClrAll". I have programed "ClsButton" and "ClrAll" to function the way I want, however I cannot figure out how to get "Send" to send through net send. Any help would be great. I have included the code so people can help me figure out what code I still need to be able to end.
Public Class NetSender
Private Sub SndButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SndButton.Click
Private Sub ClsButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ClsButton.Click
Private Sub ClrAll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ClrAll.Click
I'm writing a program that is used to enter data about different rooms in a home. On the main form there is a NUD and a combo box. The NUD is used to store the room numbers and the combo box has a list of room names. When the program starts the the NUD has a value of 1 (representing the first room) and the CB is empty. The user selects a room name from the CB and the room name is stored in an arraylist.
Now, when the user increases the NUD value the CB is cleared. Now if the NUD value is decreased then the previous room (Room 1) name is loaded into the CB. My problem is this, if the user tries to increase the NUD value again and the CB box is still empty (user did not select a room name) then the NUD value is decreased (you can't move on to the next room until a room name is entered for the current room number). However when I decrease the value of the NUD, the NUD.ValueChanged method is called again. Is there a way to prevent the NUD.ValueChanged method from being called when I decrease it's value in the code? Here is some pseudocode of my problem:
If CB.Text = "" then
NUD.Value -=1 'This line makes the NUD.ValueChanged method call itself.
CB.Text = ""
Okay, so if the answer for this question is out there somewhere (which I'm assuming it is), it's hiding between skads of tutorials on how to compile and use .dll's for normal use. I haven't quite figured out how to prune the responses I get, so I'll ask if anyone here has the answer I need while I continue to look.
The question is: is it possible to get output from a precompiled .dll during build time? I suppose output from an .exe would work as well, but I'm specifically wanting to call a .dll and include the output in the final executable itself, without actually including the .dll (this is for usage in a project in which the .dll does some encoding of data I want to be secured and hard-coded, so I'd prefer to leave the .dll out of the final project).
I know I can't give an answer, but the obfuscator I use allows for embedding three strings (labeled Application Name, User Name, and Serial Number but you could use them for anything) into the obfuscated program. You can then access those values from the program. If what you want to store is a relatively short string something like that might be an option.
That isn't quite what I was looking for. I ended up settling for writing a second application that writes the information I need to a text file, which I then embed into the main application. Not exactly the elegant solution I was looking for, but I guess if I can script it all together, it'll be ok.
I have Crystal XI release 2 installed on my pc. I want to use a crystalreports in a windows application.VS2005 comes with crystal components and I want to use these for the application. Will there be a license issue and any prerequisite and will I need to reference different dll’s? The client doesn’t want to pay an arm and leg and a license will be a big No.
