ClickOnce Deployment (BUG?)

Hello experts, There is an application (c# @ vs2005 SP1) that needs to be deployed in a very controlled way.

ClickOnce was selected to do this task.

This application works over a database and, some times, this database needs to be updated together with the code.

The problem is that not all the clients are in the same local network, so, secondary servers were deployed using windows services to transfer the information and to update and sign manifests, and then clients subscribe to the local secondary server for updates.

Not all the clients have this advantage, several need to connect directly to the primary server, so the updating process is slow and for this ClickOnce has a great feature of download updates on the background.

This is done creating Download Groups and it works well. The problem is that, when I download some files, I want to leave a small group at the server for update at the moment the administrator decide.

That works ok, but when the app is closed and opened again, the application asks the user if he/she wants to update the application because a new download is available.

I'm sure that I unchecked the "The application should check for updates" checkbox of the application updates dialog of the publish settings on the project properties.

Is there any way to stop the window's display?
I think it's a bug!

Any ideas?

Thanks in advance.

FM.

Thank you for the link. I just find a way to avoid the problem: the ClickOnce system creates a key in the registry similar to it:
HKEY_CURRENT_USER\Software\Classes\Software\Microsoft\Windows\CurrentVersion\Deployment\SideBySide\2.0\PackageMetadata\{2ec93463-b0c3-45e1-8364-327e96aea856}_{3f471841-eef2-47d6-89c0-d028f03a4ad5}\test..tion_4936abef8d16eac8_908ce6d2aef93a8e

and a binary value in it with a name like:
{2ad613da-6fdb-4671-af9e-18ab2e4df4d8}!PendingDeployment

this is the value that controls if the application should check or not for updates.

I'm attaching C# code to look recursively for the "PendingDeployment" substring at value names in the PackageMetadata key and then setting its value to two zero bytes to indicate that it should not look for updates.

Just call the NoManualUpdate() method after calls of CheckForDetailedUpdate() method and similars, and at DownloadFileGroupCompleted, UpdateCompleted events and at any place you think ClickOnce is altering the installation.

		private void NoManualUpdate() {
			RegistryKey baseKey = Registry.CurrentUser.OpenSubKey(@"Software\Classes\Software\Microsoft\Windows\CurrentVersion\Deployment\SideBySide\2.0\PackageMetadata", true);
			if(baseKey != null) {
				SearchAndDestroy(baseKey);
			}
		}
 
		private void SearchAndDestroy(RegistryKey key) {
			String[] values = key.GetValueNames();
			foreach(String value in values) {
				if(value.IndexOf("PendingDeployment") != -1) {
					key.SetValue(value, new byte[] { 0, 0 } , RegistryValueKind.Binary);
				}
			}
 
			String[] subKeys = key.GetSubKeyNames();
			foreach(String subKey in subKeys) {
				SearchAndDestroy(Registry.CurrentUser.OpenSubKey(key.Name.Replace(@"HKEY_CURRENT_USER\", "") + @"\" + subKey, true));
			}
		}
