Please read the forum posting guidelines here[^], particularly item 3.
Hi, is not a good choice for the subject of your message.
"Problem writing images to Excel", or something similar is far better. Many people will simply ignore posts with a subject like yours, therefore cutting down on the chances of your getting a useful response.

No such thing, but, whatever...
You don't "set" the connection string on the server. A connection string describes how and what a client should connect to to get at a certain database.
Since you don't make any mention of which database engine your trying to connect to, and/or how you're providing credentials to login, how the database is setup to accept credentials, ..., it's impossible for anyone to tell you what the connection string might look like.
So, have a look at http://www.connectionstrings.com[^].

A few quick guidelines:
1) A subject in the forum message should be a quick hint of your problem.
2) Typos normally tend to discourage serious experts from paying heed to your query. You ought to pay a little attention to ensure that your query is clean.

Hey buddies ........ I just started to make local area chat ............ I can send and recieve stream of data but how do i know whether the connected client(s) are disconnected or not while chatting?
One other thing I want to ask is ................. How can I send Images with each other in this clients ..... and to display one image from one client to another clients picture box? ................
I appreciate your help. Thank you.

If they disconnect, the socket dies.
Sending an image is the same as sending text really, but if you previously only sent text you'll need a way to keep text and images apart (just stick an int in front of them or something like that)

Thank you for your help .....

so .... is there a method or something to know which socket dies(i mean which user disconnected)? I think it looks silly question.
Thank you agian

Of course, when you're trying to use a socket and it throws an exception, then that's the socket which died

Hi,
use a static integer variable to count the active clients in your main thread of server.  each time a client connects count 1 up. and decrease if the clients disconnects.
bye
|
|
|
|
|
Yes, I thought in that way but .... I want to know when they are disconnected ... my question really here.... How do I know when one client is disconneted.
Thank you man.

Hi, I've written the WorkbookEvents_SheetCalculateEventHandler event to trigger for recalculation in Excel.
public event Excel.WorkbookEvents_SheetCalculateEventHandler SheetCalculate;
SheetCalculate = new Excel.WorkbookEvents_SheetCalculateEventHandler( ThisWorkbook_SheetCalculate);
The function Workbook_SheetCalculate(object Sh) triggers when there is a formula change in the excel sheet.
My aim is to read the function result from the Sh object.
for example, if A1=15, A2=17 and A3=SUM(A1,A2)
Workbook_SheetCalculate fires as soon as there is change in A1 or A2. I need to read the function result,32. Please guide me to get the value.
Thanks in advance.
