I have a problem concerning a row selection in a datagridview.
If i click on any cell in a specific row in a datagridview, I need it not to do anything, not even change the old selection in another row. I could not find any cancel for the click event on a cell. Do anyone have any solution for my problem?

Have you tried SelectedIndexChanging, and set e.Cancel = true; ?
|
|
|
|
|
There is no SelectedIndexChanging in the datagridview events.

I want to trap system mouseup and mousedown events whether they are on any application .
Thanks in advance
Thanks

I believe you have to look into windows hooks. Install a hook into the OS and handle the wndproc looking for the events as they appear. I have no idea how to do it, but you might be able to narrow you searching.

 I have a listview on my form whereas my form is the child window of microsoft visio Application. I want to drag image from my listview and drop in visio drawing.
The problem is that how we track the mouse up events in visio because mouseup event does not fire without mousedown event. and my mouse down events fired on my form.
Plase help if someone have idea about that!
Thanks
Thanks

Sorry if this is elsewhere but I look and could not find.
Can I / How do I create an arrarylist of an object.
For instance for the below object
Public Class Posts
Public Name As String
Public ID As Integer
Public Selected As Boolean
End Class
Cheers

Add a method that creates the ArrayList:
Public Class Posts
Public Name As String
Public ID As Integer
Public Selected As Boolean
Public Function MakeList() as ArrayList
Dim list as New ArrayList();
list.Add(Name);
list.Add(ID);
list.Add(Selected);
Return list;
End Function
End Class
I don't really know if this is the solution you want, as you haven't told anything about what you are trying to accomplish. If it's not, you have to surrender a bit more information...

Thanks That works fine.
The bit I was having trouble with was I thought you had to link the obeject to the arraylist somehow. I see now that arrarylist will allow you to add to it with whatever you like there is no need to "preset" it to do so.
Thanks again

Hey I solved my own question.
The problem with my code was I was returning 1 for greater than an zero for <= .
The compare function should return 1 for greater than 0 for equal to and -1 for less than. Phew on to the next stage.
Public Class Posts<br />
Implements IComparable<br />
Public Name As String<br />
Public ID As Integer<br />
Public Selected As Boolean<br />
<br />
Public Function CompareTo(ByVal obj As Object) As Integer Implements System.IComparable.CompareTo<br />
Dim temp As Posts = CType(obj, Posts)<br />
Dim mestxt<br />
<br />
If Name > temp.Name Then<br />
Return 1<br />
ElseIf Name = temp.Name Then<br />
Return 0<br />
Else<br />
Return -1<br />
End If<br />
<br />
End Function<br />
<br />
End Class

You ca use the Line method, there are examples in MSDN.

how do i authenticate any email address i accept from a form in vb.net?
im not talking about regex authentication,i mean how can i verify if it is an actual existing address?

The only way to do that is to send an email to the address with a link, coded specially for that address, to a website that the user has to click on. The web application that takes the data in the URL and uses it to figure out which address that is the one that clicked on the link. It's impossible to do it in an automated way. If there was a way to do it, we'd all have thousands of times more spam in our email boxes!

Hello everybody
I want to know that what are the different types of client server architecture ?
What is file server architecture and client server architecture ?
Examples of different databases that are of either type and what is the difference between file server and client server architecture ?

wrote: I want to know that what are the different types of client server architecture ?
I don't really know what you mean by that. There is only one architecture. You have a server and you have one or many clients that connect to the server.
wrote: What is file server architecture
It is a form of client server that serves files to clients.
wrote: Examples of different databases that are of either type
A database is a form of client server. You have a database server (e.g. SQL Server) and you have clients that connect to the database.

Thanks in advanced for all the replies!

If the .pdb is in the same location as the executable and start it with the dbgclr.exe debugger it will use it...
