Converting an Application to use the Application Updater Block from PAG

This works without a hitch. Sorry to contact you directly but apparently I don't have access to the message board from which I pulled this webpage, and you appear to be 'the man' on the board.... A problem I'm experiencing is this: I'm versioning an app that is updating 9 objects which total up to 866 kb in size. When I use my local machine's webserver (self-updating app) I have to increase the polling period from 120 to about 600 in order for all the files to be downloaded, as it takes close to 5 minutes. When I use a remote box's webserver I increase the polling period to something very high and the download takes a variant amount of time (which is a moot point because I receive an error before the polling period). The error is this: all 9 files are downloaded locally as far as the BIT[etc].tmp stage, with 0kb sizes and slowly the sizes pop in (just like when I'm running on localhost) but after 4, sometimes 5, sometimes 6 files, I receive the following error message in my logfile:

[BITSDownloader] :
The BITS service returned an error for the job with the ID '03e8db99-0ffe-4128-9589-dc335174a424';
the job's name and description are 'BITS_Files_Download_Job' and 'BITS_Files_Download_Job'.
The BITS service error message for this job is
'The server understood the request, but is refusing to fulfill it.

Do you have any ideas as to why this happens and any advice as to how to fix it/speed up the downloads? Thanks!!!

Manifest Utility returning an error

Jeff Deville — Tue, 29 Jul 2003 02:32:00 GMT

I must apologize for direct contact as well, but I also get an error when trying to create a new thread.
My problem is that running the manifest utility (either the CS or the VB version) results in an error that reads:
"A first chance exception of type 'System.FormatException' occurred in microsoft.applicationblocks.applicationupdater.dll

Additional information: Invalid character in a Base-64 string."

Error occurs in KeyValidator.cs on line 220, w/stacktrace:
"StackTrace: " at System.Convert.FromBase64String(String s)\r\n at Microsoft.ApplicationBlocks.ApplicationUpdater.Validators.KeyValidator.Microsoft.ApplicationBlocks.ApplicationUpdater.Interfaces.IValidator.Sign(String filePath, String key) in C:\\Program Files\\Microsoft Application Blocks for .NET\\Updater\\Code\\CS\\Microsoft.ApplicationBlocks.Updater\\Microsoft.ApplicationBlocks.ApplicationUpdater\\KeyValidator.cs:line 220"

I am using the manifest utility to create the XML manifest, so I don't know what could be causing the issue.

Sorry again to ask you this in your blog.

I got the same problem as Chris Wolf. I get a lot of .tmp files in the updated folder. I can't find what's problem, can you help?
Sorry to contact you directly.

As much as I enjoy hearing that other people have made the same mistake I have, I'll go ahead and just tell you:
If you received the error I did, you forgot to set the validator to RSA.

It's the stupid mistakes that are so time-consuming eh? :-)

Even if I specify a RSAKey (by using the Manifest Utility) to generate the manifest.xml, I have the same behavior and error message than Chris.

I tried with asymetric Keys or RSA or with "useValidation='false'" on the "application" node of the App.Config xml file. Lot of time already lost...

Any idea?

When my app tries to open my app.config file (in Init() of UpdaterConfiguration.vb - line is: _configuration = CType(ConfigurationSettings.GetConfig("appUpdater"), UpdaterConfiguration))

I get the following error: ConfigurationSettings.GetConfig("appUpdater")Run-time exception thrown:
System.Configuration.ConfigurationException - Microsoft.ApplicationBlocks.ApplicationUpdater.UpdaterSectionHandler,Microsoft.ApplicationBlocks.ApplicationUpdater does not implement IConfigSectionHandler.....I copied the app.config from the MS SelfUpdating example and just changed the paths to match my testing app so I can't understand why this error is occuring.

Any info is appreciated...thanks,

TJ

Do you have any How-To information for adding a post processor? I am unable to get my post processor to fire after downloading the updated files to the client...the post processor is downloaded and I can run it manually (it is an exe) and the code performs the desired actions, but I can't figure out why it doesn't run after all files are downloaded. The manifest appears to have all the correct information about the post processor...

Any ideas?

TJ,

I had the same trouble you are having. If you add a Break Point on the line and step into the code until an exception is caught, you can drill down into the 'ex' object into the Inner Exception and you'll probably find that you have a problem in your app.config "appUpdater" sections under <application> and either <client> or <server>. For example, the <baseDir> must exist and the <xmlFile> must be available when you run the application.

<application name="AppName" useValidation="true">
<client>
<baseDir>C:\Program Files\AppDir</baseDir>
<xmlFile>C:\Program Files\AppDir\AppStart.exe.config</xmlFile>
<tempDir>C:\Program Files\AppDir\newFiles</tempDir>
</client>
<server>
<xmlFile>http://www.domain.com/updates/Manifest.xml</xmlFile>
<xmlFileDest>C:\Program Files\AppDir\Manifest.xml</xmlFileDest>
<maxWaitXmlFile>60000</maxWaitXmlFile>
</server>
</application>

I am using Application Updater for my App and KeyValidator for validation. All goes fine until after the download, the validation starts to happen, all files are validated but for an .exe file. I dont understand , what has got against an .exe file.
Thanks
