It seems that I'm stuck on something small but I've been working on it for quite some time and I'm exhausted...
I have a method that returns a bool whether a TcpConnection was successful or not...
The method attempts TcpListener.AcceptTcpClient
however I want it to return false if no client has been connected within a specified time (e.g. 2000 milliseconds)...
How can I achieve this? I attempted the .BeginAcceptTcpClient and .EndAcceptTcpClient but these still block OR if I use the Thread.Sleep() I block the method from accepting any connecting client.. I need the result to be returned if a TcpClient is accepted or the operation 'timed-out' - whichever comes first. Please help!

something like this?
[pseudo C#]
private bool GetNext(out TcpClient client)
{
client = null;
while ((less than 2000 ms has elapsed) and (!TcpListener.Pending())
{
Sleep a bit
}
if (TcpListener.Pending())
{
client = TcpListener.AcceptTcpClient();
return true;
}
return false;
}

Hello,
I have a datagridview in my application.
I want to add an option that the user could resize the datagrid (table) as he wants (for example when the mouse is on the border of the datagrid, the cursor will change to resizing cursor and he could drag it (and so resize the datagrid).
How can i do it?

Most people arrange for the resize of the FORM rather than the control. If your DGV is set to dock.fill then it will be the control that expands when the form is resized.

OK, But i want the DGV to be resized inside the form. For example if the mouse on the border of the DGV, it's cursor will be changed to resizing cursor and the user could drag it to its new size.

There are loads of hits for this, on Google.
One of them was Allow the User to Resize Controls at Runtime[^], have a look and see if it helps.

So you have loads of unused/wasted space inside your form - I'd call this lousy design, a form should be reasonably tight with no wasted space on it.

Hi,
I used this tutorial : http://www.codeproject.com/KB/cs/ResizeControlsRuntime.aspx
I have below my DGV another control (DGV), but when i resize the first DGV (below the second DGV), the second DGV hides part of the resizes DGV (it's on top of it). I have a resize option to the second DGV too.
What can i do that the resized DGV will be always on top of all other controls (DGV)?
If i can't do it, what can i do so the first DGV will be always on top of other DGVs (when i resize it)?

While I have not looked at the article - they are articles, designed to demonstrate a particular aspect of, in this case resizing, .net. You should not take this as a "good" design for UIs, thats not what the author was trying to achieve.
If I am doing a form that is resizable then there will be 1 or more list controls (ListView/DGV etc). These are the controls I will have docked as fill, all other controls will be placed inside panels and docked to an edge. This then allows the FORM to be resized and the list control expands. If there are 2 DGV then use a splitter control and allow the user to resize the DGVs.
I have NEVER designed a form where a DGV can be resized OVER THE TOP of another DGV, I would consider this a bad design.

I have many data in a DGV and the user wants to be able to resize a specific DGV to see most (or more) of the data in the DGV. I have some DGVs in the same application ( i cann't split them to some tabs for example).
So when i resize the first DGV the second DGV hides part of the data.

Put the 2 DGVs in a split panel.

I agree with Mycroft. Use splitter controls to force the second DGV to be downsized instead of overlapping. You could do the same thing manually in resize events, but unless you've got weird layout elements that can't be changed using splitters and proper docking/anchoring will make everything much easier to implement and less likely to have weird bugs.

It doesn't sound like what he's doing, but if you've got multiple resizable controls on your form having the others automatically resize themselves around the one you're adjusting manually could be useful.

Yah maybe, it still sound like a crappy UI design. I'd go for a splitter or split panel rather tha have one DGV on top of another, control is going to be a bitch. I do wonder why a tab control or a stack panel of DGV's is not viable. There are so many options other than overlaying one control on another which I consider lousy design.

IF you need to look at 2 or more at once tabs/stacked panels won't work. Excepting a designer I can't see any good reason not to use splitters.

Dear all,
we are facing a unique problem with the windows service which is running on windows server 2003.
After starting the service 3 to 4 days we are getting a error.
Error: Connection request timed out
After that service is ubale to establish connection to the oracle database.
Once the service restarted it works fine and again after 4 days again the same problem.
Can any one know the solution?

Check whether your are properly closing the database connections after every database transactions....
it might so happen that the connections are not closed and hence the database not allowing new connections..

Hi Roy,
Yes, we are taking care of closing the db connections in the finally block.

I would like to change the background color of the richtext box when it is disabled. Eventhough i am assigning the backcolor to the desired color, it is not changed. The background color always comes as gray when it is disabled.
public new bool Enabled
{
get
{
return base.Enabled;
}
set
{
if (value != base.Enabled)
{
base.Enabled = value;
base.BackColor = (value == false) ? Color.Yellow : Color.White;
base.ForeColor = (value == false) ? Color.Black : Color.Blue;
}
}
}
Can anyone suggest me how to change the background color of the Richtextbox when it is disabled?
Thanks in advance,
Mutpan
