Re: Combo box Not Active9-Jun-09 8:57 Not Active 9-Jun-09 8:57  A common problem. You can either set an internal flag that tells whether the combo is being loaded during initialization or disable the events and reenable them after the combo has been loaded. only two letters away from being an asset Re: Combo box jonhbt9-Jun-09 9:06 jonhbt 9-Jun-09 9:06  I am using a flag but the problem is that the selected value remains the same even though I change the selection. how can I solve that please? Re: Combo box Not Active9-Jun-09 9:25 Not Active 9-Jun-09 9:25  What do you mean, "the selected value remains the same even though I change the selection"? You're original question was how to work around the event firing during initialization. Now, however, it seems the problem is something else. If you want help around here state the problem clearly.

I want to have one window that has a GUI with buttons and the other to be a console window where all the output will be displayed. I was wondering if it is possible to use Console.WriteLine in a WinForms application and if so, how would I go about that? Thank you! Re: Creating a Console in a WinForms Application Not Active9-Jun-09 8:17 Not Active 9-Jun-09 8:17  You can't use Console.Write but then again you don't have to. A TextBox, or ListBox even, properly formatted will look just the same. only two letters away from being an asset Re: Creating a Console in a WinForms Application Kevin Mark9-Jun-09 8:35 Kevin Mark 9-Jun-09 8:35  Ok. Thanks! PS: Thank you again for the quick reply! Re: Creating a Console in a WinForms Application DaveyM699-Jun-09 8:48 DaveyM69 9-Jun-09 8:48  Console.Write/WriteLine writes to the Debug Output window. I don't know if it's possible to redirect this. Dave BTW, in software, hope and pray is not a viable strategy. (Luc Pattyn) Visual Basic is not used by normal people so we're not covering it here.

(Christian Graus) Re: Creating a Console in a WinForms Application Not Active9-Jun-09 8:55 Not Active 9-Jun-09 8:55  Console.Write writes to StdOut, which in the Visual Studio IDE is the debug window. In a console app, its the console window. You can mess around with setting the stdout but why bother when there are other methods available in a WinForms app. only two letters away from being an asset Re: Creating a Console in a WinForms Application Alan N9-Jun-09 9:04 Alan N 9-Jun-09 9:04  Hi, Create a standard winforms project and then go to the project properties and change the output type to console. Magic, you'll have a console and a form. Alan. Sharing Internet using bluetooth devices Venki569-Jun-09 7:57 Venki56 9-Jun-09 7:57  Hi, I have internet connection to my desktop PC.

Upon completion of processing looks again and continues... I don't know if it is wise to keep looking at a folder every second for files, please advice on that. If it is not then maybe put a wait and look every 20 minutes or so. Please help!! I don't need code to look for files, etc. I just need some guidance on how to build the service with a thread.

The only really good way is for the file creator to signal you when a file create or update has been executed to completion. I see no need to use threading, unless maybe if you want to watch several folders. You might want to tell us more about what the files are about, and what you intend to do to them.

Re: Windows Service and Threading Saamir9-Jun-09 9:31 Saamir 9-Jun-09 9:31  Hi Luc, As always thank you for your response. My windows service in short looks at 3 folders for .csv files, parses them and does some database updating. From time to time there are files added to these folders so I have to keep looking at a certain interval in these folders (currently configured every 20 minutes) I decided to implement the following method: http://en.csharp-online.net/Creating_a_.NET_Windows_Service%E2%80%94Alternative_1:_Use_a_Separate_Thread[^] Please let me know if this is not a good method, I would hate to crash the server because that is where this service will be loaded Thanks Sameer Re: Windows Service and Threading Mycroft Holmes9-Jun-09 14:26 Mycroft Holmes 9-Jun-09 14:26  We do exactly the same thing except we use a winforms app to give feedback to the user, it chacks every 2 minutes and disables the timer while checking (otherwise eyou get multiple threads) We have implemented a delay in the reading of the file to avoid touching files still being written by setting a flag with the time of first seeing the file, if more than # period has elapsed since seeing the file we can then process it. This has been working perfectly for the past 4 years, at 2am it processes up to 1200 files an hour. Never underestimate the power of human stupidity RAH Re: Windows Service and Threading Luc Pattyn10-Jun-09 8:37 Luc Pattyn 10-Jun-09 8:37  Hi, one way to overcome the problem you don't get events when a file creation/update is completed is this, assuming you're in charge of the producer's code: - look for "event files", recognized by a specific characteristic, maybe a new file extension .EVE - create/update your data files in any way you see fit; when done, create a short .EVE file containing the full path of the data file. Such file will be written atomically since it fits in a single sector.

Re: Windows Service and Threading Abhijit Jana9-Jun-09 6:46 Abhijit Jana 9-Jun-09 6:46  Ok, there are multiple way to do that. As Luc suggested you can use FileSystemWatcher Class to check a folder. If any new files created it will fire an event and based on that you can do the required operation. you can use TimerDelegate with windows service to monitor on a specific duration. Recentenly I have completed a similar application. Please let me know if you have more doubts. Hope I can help you in this. Thank you. cheers, Abhijit CodeProject MVP Web Site:abhijitjana.net Re: Windows Service and Threading Saamir9-Jun-09 9:28 Saamir 9-Jun-09 9:28  hi Abhijit, Thank you for your response. I went with the following procedure and the service seems to be running fine. Please advice if this is not a good idea for a windows service http://en.csharp-online.net/Creating_a_.NET_Windows_Service%E2%80%94Alternative_1:_Use_a_Separate_Thread[^] Sameer Re: Windows Service and Threading Abhijit Jana9-Jun-09 10:42 Abhijit Jana 9-Jun-09 10:42  Samir, That is fine. I have one question regarding your application. How file are submitting into the Folder? Is it submitted by any client? Is there any possibilites the more than thousand files created on that folder? cheers, Abhijit CodeProject MVP Web Site:abhijitjana.net Re: Windows Service and Threading Saamir9-Jun-09 10:52 Saamir 9-Jun-09 10:52  Happy to hear that it is a good method. A different client creates and dumps these files. Usually, there is a single file at one point and what my application is doing is processing these files and dumping it to an Archive folder. Sameer Re: Windows Service and Threading Abhijit Jana9-Jun-09 11:05 Abhijit Jana 9-Jun-09 11:05  I was asking because in my case there can be possiblity of many file submitted at the same time, because files are submitted via Web services. So I was wondaring with behaviour of FileSystemWatcher that it can manage that hughe change list or not. So what I did, I have stored the file name in DB while client storing the file into the folder, means my Web service save the posted file and store the Filename in DB . Now what I did, Windows Service read the DB load 100 Files name in DataSet, Process them one by one and update the dataset, After complete the all processing I have update DB with the updated dataset and Load the next 100 Records. Now If there is no records, I have used a DelegateTimer which will monitor the database with 15 min interval to file come. If file is there, I stopped the current timer and process those data. cheers, Abhijit CodeProject MVP Web Site:abhijitjana.net
