I have written a Web User Control to draw lineGraph. I have a method in it, where the parameters are passed such as title of the chart, all the data thats needed to draw the line graph. The problem is - from the calling Form (program) I have an array of data for which I need to draw multiple charts on the webpage. The program iterates thru to create the user control multiple times, but I see only one chart. I inserted panel, and did all sorts of the things..but nothing helped. Any ideas would be appreciated. Thanks / Vinayak

I have a treeview control which gets populated with the data from the database. However, as long as the number of nodes that need to be created are within 500 I have no problem. But when exceeds the number, it almost freezes my web app. I am trying to find out if I could use a paging mechanism for the treeview control to accomplish the performance and speed. Any leads please. Or any remedies for my original problems. thanks / vinayakkatkam@yahoo.com

I have written an application that runs on Windows Service. It runs fine (I overcame some of the problems I had with it earlier). It does perfectly everything that it is supposed to do - the only problem - after I start the service it runs for about a day or two and it halts (stops) by itself in the middle of the night. When I see it is stopped, I restart it and it gets back to its normal operation. I have to keep watching until it stops again. Is there known issue that can resolve this problem. Help would be highly appreciated. (vinayakkatkam@yahoo.com). Vinayak Katkam

Yes, the file is physically there, yet - the service cannot transfer it! It did not remove the file on the first attempt. However, if the transfer is successful, I am removing the file from the remote server. Your next point is a valid one, that is about removing the file despite its failure to tranfer. I have blocked the code in two try blocks. In the first try block I try to tranfer the file and remove only if it is successful. Else do not enter the remove block. I liked your approach to the problem. Thanks / Vinayak

Thanks Colin. I have an ftp component that returns the list of files in the source directory as a dataset. But once the file is failed to be tranferred via the Service Component - I go for the next one tranfer it. When the service makes the next attempt - is gets the failed file in the list but fails to transfer saying that "the file can not be found". :-(

I have written a service that grabs the files in a source directory on a remote server and ftp's to local directory. The service monitors the source directory of the server and collects the files as they come in. The Problem: Sometimes the files are physically present but the service recognizes and at the time of transfer it cannot get handle on them. I gut feeling is - the service tries to grab the file when it is in the process of being tranferred to the source directory. It loses the handle on the file and can never recover thereafter. Any suggestions ! Thanks / Vinayak

you need to add reference to the project in your C# project. This is a guess.

I have written a couple of windows services apps. when I test them they run fine and do what they are supposed to do. But after a couple of days or so, they are still running but do not perform the tasks. Any suggestions, if what could be causing it ! Would really appreciate any help.
