Hello. I've got a bit of a strange error and I can't seem to find much information about ways to fix it. I have a ClickOnce deployed application that is accessed by multiple clients, all with various Windows operating systems. It seems this error only occurs for those with Windows XP, but not for all Windows XP users. I have a timer that kicks off every 10 minutes that makes a call to ApplicationDeployment.CurrentDeployment.CheckForUpdate(). Within this call, I get the exception -- Error: System.Deployment.Application.InvalidDeploymentException: Exception reading manifest from http://server/AppName.Client.application: the manifest may not be valid or the file could not be opened. ---> System.Deployment.Application.InvalidDeploymentException: Deployment manifest is not semantically valid. ---> System.Deployment.Application.InvalidDeploymentException: The name of the application reference identity as invalid characters: AppName.Client.exe. at System.Deployment.Application.Manifest.AssemblyManifest.ValidateApplicationDependency(DependencyAssembly da) at System.Deployment.Application.Manifest.AssemblyManifest.ValidateSemanticsForDeploymentRole() --- End of inner exception stack trace --- at System.Deployment.Application.Manifest.AssemblyManifest.ValidateSemanticsForDeploymentRole() at System.Deployment.Application.Manifest.AssemblyManifest.ValidateSemantics(ManifestType manifestType) at System.Deployment.Application.ManifestReader.FromDocument(String localPath, ManifestType manifestType, Uri sourceUri) --- End of inner exception stack trace --- at System.Deployment.Application.ManifestReader.FromDocument(String localPath, ManifestType manifestType, Uri sourceUri) at System.Deployment.Application.DownloadManager.DownloadDeploymentManifestDirect(SubscriptionStore subStore, Uri sourceUri, TempFile tempFile, IDownloadNotification notification, DownloadOptions options, ServerInformation serverInformation) at System.Deployment.Application.DownloadManager.DownloadDeploymentManifest(SubscriptionStore subStore, Uri sourceUri, TempFile tempFile, IDownloadNotification notification, DownloadOptions options) at System.Deployment.Application.DeploymentManager.BindCore(Boolean blocking, TempFile tempDeploy, TempDirectory tempAppDir, FileStream refTransaction, String productName) at System.Deployment.Application.DeploymentManager.Bind() at System.Deployment.Application.ApplicationDeployment.CheckForDetailedUpdate() at System.Deployment.Application.ApplicationDeployment.CheckForUpdate() at AppName.Client.MainFor

Click the link, watch, wait a moment, and you'll have your answer(s)

From the code you posted and the error you say you are getting, I think your brackets are off. You should have { } wrapped around your class methods (Main and ConvertTime) and also to enclose them.

One suggestion would be to check out the members of the StreamReader and StreamWriter classes, along with sample code. Try using Read() or ReadLine() instead of the ReadAllLines() in your while loop condition. http://msdn.microsoft.com/en-us/library/system.io.streamreader.aspx[^] http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx[^] Also, you might want to consider copying the data as you read it to a new text file and overwriting the old one when you are finished. And don't forget to close the filestreams when complete.

Can those be in their own Services?

Actually, yes, and they are.. I guess I should have mentioned that part :) The way I had it implemented before I made the initial post was I pretty much let it finish everything until it was able to submit the data to the other services. But Windows spazzed out because it couldn't stop the main service until it finished the preceding operations. What I ended up doing was defining like a project "state" DataTable that could be exported and imported again when the service restarts. Your suggestion was well-taken -- pretty much made the current operation finish and then updated the project state based on that. I don't know if using a DataTable is the best approach, but it seems to work much better, since it takes considerably less time to stop the service. Still open to suggestions if you or anyone can think of a better approach, though!! I guess I'm in a C# experimentation phase :)

Looks like they are constants, found this site which describes them and how to use them, hope it helps... http://msdn.microsoft.com/en-us/library/aa929762.aspx[^]

Hello! I recently started writing my first Windows Service project in C#, and I'm at a point now where I have a lot of time to perfect things before I continue. I was wondering what's considered generally "good practice" with regards to Windows Services. Specifically, the stopping mechanism. When my service starts, it kicks off a few threads that perform some file manipulation. When the service stops, I want it to shut those threads down gracefully. Ideally, shutting down the service puts the file system in a state where the manipulation can be easily resumed upon restarting the service. So, when shutting down the service, I'd prefer to let one of the threads (if it's currently doing work) finish the works it's already started, but in some cases, this can take several minutes. Is this considered bad practice, or is this something I shouldn't really be concerned with? Are there other things anyone thinks I should consider?

Dunno if this is the sole reason, but your column tags don't exactly match up... ... ... instead col2 and col3 should be capitalized, Col2 and Col3, to match

Thank you both for your responses. The resources and general information you gave will keep me busy and are a great starting point. Thanks so much!

Hello! I am writing a Windows service that requires various user-defined settings in order to work. The solution uses multiple class libraries which are all linked with these user-defined settings. A coworker suggested that I use a dataset to do this, but being new to C#, I'm not exactly sure how I would go about doing this. I think I get the concept of a dataset, but I don't particularly understand how the service would know that the settings were changed after the service has been built, installed, and started. The searches I've done today haven't really given me any relevant information, and I was hoping that somebody could point me in the right direction with a source or suggestion? Any help would be greatly appreciated :)

I came across this article a few weeks ago, take a look and hopefully it will help... http://msdn.microsoft.com/en-us/library/ms173196.aspx[^]

Unless you are doing this with C#, I think this is the wrong board for this question...

http://msdn.microsoft.com/en-us/library/system.net.sockets.networkstream.aspx

You should be able to connect to the localhost with windows authentication mode. Once you connect you can create databases and such. Doe sit give you an error message when you try to connect to the localhost?

There is a section on this page specifically for exporting to .xls files with other configurable settings... http://msdn.microsoft.com/en-us/library/ms227794.aspx

I am new to C# so I've been browsing the MSDN libraries to see how to use certain classes. After reading your post, I looked for and found the description of the UdpClient class. http://msdn.microsoft.com/en-us/library/system.net.sockets.udpclient.aspx There are examples on that site, but specifically you need to close your server connection, as the others were telling you. So, somewhere before the user closes the program, you have to call server.Close() I would recommend a finally block in your receive() method and closing the server there. But you would have to define server before the try block for this to work.

Thanks SO much... I don't know why it didn't dawn on me to use a while(true) statement... silly me! But thank you, that helps a lot!!

Hello. I'm new to C# (switched from Java) and I am trying to see if there is a way to keep a thread running indefinitely, with no timeout. I have a console application written, but I need it to run more like a windows service in that I want all threads to run until they are told to stop. Is there a special class that will help with this, or does anyone know of a good resource that I can learn more about this specifically??

Thank you, that helped clarify some of the event concepts for me. I guess I'm wondering now whether the filesystemwatcher acts as a thread... meaning does it listen indefinitely while the main program works until it hears something? Or does it have to be wrapped in a thread to do so?

Hello. I am new to C# (used Java originally), and I was wondering what would be the best way to handle file events in a console application. Specifically, I need to monitor a bunch of directories to see if new files are being added, and then do something with them if so. I guess I'm confused because I need to thread the watchers, but am unsure how/where to handle their corresponding events. I have been looking around for resources but am coming up on threading samples and event samples but not any combination of the two and so I don't know exactly where to start. If anybody has a suggestion or resource, I would greatly appreciate it!!
