Re: Web service question Ista11-Dec-05 15:43 Ista 11-Dec-05 15:43  well a web service is a (web) and is know way independent of IIS. You could host IIS on a win2k machine. It doesn't have to be a server. Now you can imitate the web service by doing remoting. and just open a port or listen on port 80 for data coming through. After all, a web service wraps remoting. Its a simple concept but you'll need to practice it. http://www.csharphelp.com/archives2/archive422.html[^] I would say set up a win2k machine that doesn't exhibit such behavior. If not, do remoting but it will be a learning curve. Its a shame when companies do this over a few dollars. Hes going to spend more in the long run. Make sure you do tons of exception handling. I'm not an expert yet, but I play one at work. Yeah and here too. Re: Web service question Steve Messer11-Dec-05 19:05 Steve Messer 11-Dec-05 19:05  Thanks for the information. I don't believe it's over a few bucks, I believe he has two motivations. 1. He is from a non-Microsoft background... and he doesn't want to use ISS any version on any machine. 2. He wants to find a way for the client to send info directly to our application with out a middle man or web server. I am with you. Why reinvent the wheel. I will look at the remoting to make our point to him. Cheers How to Filter data table kotteeswaran9-Dec-05 6:59 kotteeswaran 9-Dec-05 6:59  Hi, Im a new guy in C# dev. I need to develop a component The requirement is.. I will be fetching a recordset from database which is of type dataset.(no problem for me here) I will be taking the datatable out of the dataset which is having four coloumns..ie OrderID,OrderDate,ItemName,ItemID. The requirement is to generate a XML file for each OrderID in the datatable. One OrderID may be associated with Multiple ItemID and ItemName... I need to filter out the table so the i take One OrderID and associated coloumns(orderdate,ItemID,ItemName) and send those values to other method cof generating the XML string. Here im having some trouble , How to filter out and form the child table which is having One orderID and other values?.. Please give some eg code thanks in advance kotteesh Happy coding!! kotteeswaran Re: How to Filter data table Guffa9-Dec-05 7:09 Guffa 9-Dec-05 7:09  Create a DataView for the table. --- b { font-weight: normal; } Re: How to Filter data table kotteeswaran9-Dec-05 7:11 kotteeswaran 9-Dec-05 7:11  Guffa, Can you give some sample code or link thanks Happy coding!! kotteeswaran Re: How to Filter data table Guffa9-Dec-05 7:19 Guffa 9-Dec-05 7:19  MSDN: DataView Constructor (DataTable, String, String, DataViewRowState)[^] --- b { font-weight: normal; } RichTextBox - Sending "zoomed" output to bitmap FinallyInSeattle9-Dec-05 6:24 FinallyInSeattle 9-Dec-05 6:24  I have code that allows me to basically write the contents of a richtextbox to a bitmap (sending a EM_FORMATRANGE using SendMessage). This code works fine, but it always draws the text "normal size" regardless of the setting of ZoomFactor in the RichTextBox. How can I get the "zoomed" verison of the text into a bitmap? Thanks in advance! Re: RichTextBox - Sending "zoomed" output to bitmap Polis Pilavas9-Dec-05 12:03 Polis Pilavas 9-Dec-05 12:03  Why don't you try zooming into the extracted bitmap? Let me know if you need the code to zoom into an existing bitmap Regards, Polis Can you practice what you teach? Re: RichTextBox - Sending "zoomed" output to bitmap FinallyInSeattle9-Dec-05 12:07 FinallyInSeattle 9-Dec-05 12:07  Hi Polis, I'm interested in the "zoomed" output of the RichTextBox because it does a nice job of scaling the fonts rather than the "blocky" output of scaling a bitmap. Is this what you're referring to? Thanks! Lori Polis Pilavas wrote: Why don't you try zooming into the extracted bitmap?

Sorry I can't help you with that since I don't know how you get the bitmap in first place. If I were you, most probably I would extract the bitmap like you do, then zoom into the whole image, and crop out the parts I wouldn't want to show. Regards, Polis Can you practice what you teach? Adding Rows To Data Set jasonwinn9-Dec-05 5:33 jasonwinn 9-Dec-05 5:33  Hello there! I have been working on this and cannot get it to work for the life of me.

TCP Socket Problems c#guy38119-Dec-05 4:20 c#guy3811 9-Dec-05 4:20  I have a client/server relationship which I use to update files on connected users' computers. It uses Asynchronous Socket operations and sends binary data over TCP sockets. The connections are maintained indefinately until the client or server disconnects, or a client encounters an error and closes the connection. The problem I am having is that after a few days, the server stops sending messages to its clients. The number of clients right now is about 20-25, which are connected at all times. I see from the message logs that it is receiveing client requests, but it is not sending a response to those clients. The server is set to send updates at 12:30 AM every day, but after about 4 days it stops sending anything. I know it would be helpful to have the code, but not knowing where exactly the problem is, it is hard to post code, and there is A LOT of it. Any ideas on what the problem may be are appreciated. Thanks in advance! Re: TCP Socket Problems Ista9-Dec-05 16:24 Ista 9-Dec-05 16:24  I fixed this problem once. I can't remember the solution, but I think I had a thread to keep it alive. Becuase the CLR tries to shut it down after a certain period of time. Nick I'm not an expert yet, but I play one at work. Yeah and here too. Re: TCP Socket Problems Ista9-Dec-05 16:26 Ista 9-Dec-05 16:26  I would also attach and event counters to it, to see if the OS is shutting it down and something sporadic isd happening. I'm not an expert yet, but I play one at work. Yeah and here too. Re: TCP Socket Problems mcljava12-Dec-05 8:13 mcljava 12-Dec-05 8:13  Beware of IP address changes. If your clients are DHCP based and the IP resets at somepoint during your conenction then you will have a problem. For example if your DHCP address lease is for 3 days then you might want to visit that. Also, make sure your read logic in the server and client is looking for its corresponding peer to drop. I.E. if recv() returns 0 or if a SocketException occurs, depending on how your code is structured. The application should free up any socket related resources and return to a steady state. For the server, this means listebing for new connections. For the client, either exiting or initiating a connection retry sequence. Finally have you stress tested your server? How long can it sustain a constant message flow? If the answer is not indefinitely then you might want to revist the server code to make it moe robust. If it were me, I would make sure the server is 100% bullet proof under load to understand how it performs and what to expect in terms of client communication. Remember any test harness you build should use the same client connection logic. Once you nail that down consider creating a library so that you can build client applications w/o fussing with the connection details. Mike Luster Re: TCP Socket Problems c#guy381112-Dec-05 9:02 c#guy3811 12-Dec-05 9:02  The clients and servers both use a .dll for connection/send/rcv data. The server assigns the new socket to an ArrayList when a client connects, and gives the client an associated number. When a client disconnects, the server removes the client at the ClientNumber position in the ArrayList, then updates all necessary ClientNumbers to the correct position. While the update is going on, the server is suspended, IE, it can not accept new connections until the update is complete. The client dll backend catches an error, performs cleanup procedures, then trys to reconnect at a random interval. The connect/disconnect portion of the program isnt the problem. Even when the server hangs it still accepts/disconnects. IP Addresses are static. That shouldnt be a problem. Im beginning to think that it may be some of the other software running on the actual server with my server program. I think the backup software is locking the database when the server tries to update file listings. When I came in this morning, the ListView telling me what the current files were was empty, suggesting it failed contacting the database. If that is the case, then when it tries sending files, it wont have any references in the DataSets, and will simply return from the function without sending anything. Ill keep everyone informed incase the problem may come up with someone else. Closing form ControlBox zaboboa9-Dec-05 3:42 zaboboa 9-Dec-05 3:42  Hello, Is there a way when we close the form using X (top right corner of the form on the ControlBox), to make it act as a cancel event, when I press Cancel button on this form. In other words, to run cancel button event? Thank you Re: Closing form ControlBox kobymeir9-Dec-05 8:42 kobymeir 9-Dec-05 8:42  every form has two properties : AcceptButton: called when the user press "ENTER". and the button appears differently. CancelButton called when the user press "ESC" or click the close button. in both cases the form calls the click event of the according button. hope i helped . Pls.
