You don't need Message Queue. All you need is Remoting.
You can implement this in two ways. Both would require that you have a central server application that your chat client checks in with to see who's logged in. This means that the Chat application is running on that persons computer(!), not that the machine is logged in!
You can have the central server dole out who's Chat application is logged in and what it's IP address is. This way, you can have direct communication between two clients without the need to have the server relay message for you. This would make GROUP chats difficult to implement though. It also greatly complicates the code on the client side, but simplifies the code on the server side.
The other method is to have the central server do all the message relaying for you. This would have the opposite effect on code complexity. The client side is simplified, but the server side gets complicated. This would give you the beneift of easier implementation of chat rooms though.
You could check out Picture Chat using C#[^] here on CP for a good example of how to implement chat.

Hi Senthil,
Could I ask you how you achieve the peer discovery ? Can it be done
without using .Net remoting but just with c# ? Is it based on
some peer discovery protocol ?
Thanks for your help !

Is it possible to open html page in window applicaion?
the program language is c#.

Yes, use the mshtml control. There are many articles on codeproject about how to do this. here's one for example. I recommend you search the forums and articles before posting next time.

I could be wrong, but I believe the Genghis Project for .NET includes a wizard control that eases the creation of wizards.

I've got a MyButton : Button class, and I would like to handle the events (like MouseMove, MouseUp, MouseDown) not in the form class but in the MyButton class. In the class where and how can I do it, because adding handler in MyButton constructor occurs error:
Form1 form;
this.MouseDown+=new System.Windows.Forms.MouseEventHandler(form.Mouse_Down);
|
|
|
|
|
override the OnMouse** methods of you base class (within your MyButton class)

..embedded control on each row??
I know a column can be created that will show a combobox, then all rows of that datagrid will have a combobox in that column.
BUT...
Is it possible to have a column that will allow you to show different controls on different rows?
E.g. visualise the following 2 column table, which has 3 rows:
Col1 Col2
Row1 Combo
Row2 Checkbox
Row3 Textbox
How can this be done? Would greatly appreciate the assistance of the .NET/c# experts out there...!
|
|
|
|
|
I don't think this is possible. The only thing that comes to mind would be if you set the column to type System.Windows.Forms.Control then did some hack to get each row to display the type of control you want, but I'm thinking this isn't possible. Maybe someone with more experience in this area can give you a more solid answer.

Hello,
I developed a Smart Device Application but some textBoxes are hidden when the SIP is activated so I want to reach the following situation (for now it works that the Input Panel is raised when the user clicks on a text Box):
whenever the user clicks on a text box and the Input panel is raised, the
code determines if the textbox is hidden by the raised input panel.
-if yes, the form is scrolled upwards till the focussed text box is above
the height of the input panel. this way the user can see what he is typing
in the textbox.
-when the input panel is disabled, the form contents are scrolled back to
the position they were before the panel was raised.
Can anybody help me with that problem?
thx

Hi gurus,
How can I get the list of installed network adapters (hardware & virtuals) and get their informations? (IP address)
Can any one show me a sample code to do so?
Thanks.
Best regards. 
There is no spoon.

|

Add a reference to the System.Management dll, which gives you access to WMI (Windows Management Instrumentation). WMI can give you the list of network adapters and IP addresses; MSDN has several good examples, I suggest you search there.

Hi~
A C# program calling a C++ dll to create a window using P/Invoke.
After the C# program was KILLED (not terminate the program normally), the window created by C++ dll still exist. I would like to ask how to clean up the C++ dll (process? or thread?) after the C# program is KILLED.
THanks~

Hello,
I am currently working on a Smart Device Application with a TabControl and four TabPages. I want to add a vertical Scrollbar in one TabPage. Does anybody know how I can realize that??
Best Regards

I tried it in that way: with the following lines in the constructor:
this.vScrollBar1.Maximum = tabPage1.Height + this.ClientSize.Height;
this.tabPage1.Controls.Add(this.vScrollBar1);
and the following EventHandler
private void vScrollBar1_ValueChanged(object sender, System.EventArgs e)
{
this.tabPage1.Top = -this.vScrollBar1.Value;
}
Unfortunately this does not work. Nobody an idea how it works to scroll within a tabpage of a Smart Device Application
regards

Hi ,
My project needs to create a folder broswer to allow user to choose folder path. however, I can find any build in control to do this.
I have found from MSDN, it has one called FolderNameEditor.FolderBrowser, inside System.Windows.Forms.Design namspace, but I still can't use it. My computer is using dotnet 1.0 verison. is it impossible to use this control ?
Does it only support for dotnet 1.1 or above??
One more, I would like to load current user desktop path, and MyDocument etc. to a tree, but how I can get these type of paths?
Thank you.
