NetSparkle - AutoUpdate for .NET Developer

New Post: Questions from a netSparkle newbie.

refinedmusic — Fri, 17 May 2013 14:29:16 GMT

So I've just integrated NetSparkle to one of my apps and the initial test are all good. I have my appcast.xml set up and release notes html etc and the program detects new version and downloads it. However i always get a broken DSA signature box. I've done the DSA signing and added to the appcast.xml but maybe I'm signing the wrong thing?

my steps are:

Build program
Package everything to a winrar self-extracting .exe (NetSparkle doesnt support .zip files right?)
NetSparkleDSAHelper.exe /sign_update PACKAGE_NAME.exe NetSparkle_DSA.priv
Add the signature to appcast.xml and upload to server
Upload new package exe
Run application, download the update.

Is there a better way to package up the update rather then a self-extracting zip file?

Thanks a lot!

Description:
Will use the assembly entry point instead of current directory to pinpoint where to update.

Created Issue: Install location issue. [19344]

Coderus_Troy — Tue, 12 Feb 2013 16:11:44 GMT

When running NetSparkle if the installed files were put elsewhere from where the application was running it would sometimes find the wrong working directory. It was found this happened because it was using "Environment.GetCurrentDirectory;" to get the location.

Instead " System.Reflection.Assembly.GetEntryAssembly().Location; " has been used as this would consistently give the correctly install location, regardless if the install folder was changed or not.

New Post: RAR File Support

Hello,
I just added rar support. In case you need it, here is the code;

using (RegistryKey registryKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Classes\\WinRAR\\shell\\open\\command"))
{
        //check if winrar exist
        if (registryKey != null)
        {
             string path = (string)registryKey.GetValue(null);
             path = path.Substring(1, path.Length - 7);
             string targetFolder = Application.StartupPath;
             installerCMD = String.Format("\"{2}\" X -ep -o+ -m3 \"{0}\" \"{1}\"", tempName, targetFolder, path);
         }
         else
         {
              sparkle.ReportDiagnosticMessage("Winrar couldn't be found");
         }
}

New Post: Including public key file with a .msi

jamesingham — Sun, 13 Jan 2013 22:48:20 GMT

So I've just been through the docs and got my package manager working nicely, however the DSA is always failing. I'm 100% I'm following the docs correctly, but think I'm getting confused when creating a MSI. I have the .pub embedded to the compiled .exe but NetSparkle is downloading a .msi, not the .exe. I even tried this downloading the exe and it was still failing.

Is it easier to just distribute this over https?

New Post: Workaround for WPF

Fhaze — Thu, 29 Nov 2012 16:09:14 GMT

If you are trying to use this in a WPF application, when it goes to install, you will see a whole bunch of errors saying "Your program stopped working"...blah blah blah. To fix this...

Download the source code.

Go into the trunk, open the project there.

You are looking for "public static void Install(Sparkle sparkle, String tempName" method in the class NetSparkleCheckAndInstall

Where it says "Environment.Exit(0);" Replace with "System.Windows.Application.Current.Shutdown();"

Add your WindowsBase, System.Xaml and PresentationFramework references

Recompile, add the new .dll to your program and away you go.

New Post: AssemblyInfo.cs version

zaz_master — Tue, 27 Nov 2012 11:02:21 GMT

Hi guys!

I'm using NetSparkle inside my application as external dll. Deployment process performs through msiexec. But I have problem.

Why does the version in AssemblyInfo file not increment? It's still 1.0.22, but the latest version of NetSparkle is 1.0.83.

Msiexec cannot update this assembly during deployment, because the version is still the same.

Thanks.

New Post: How does the next update access data files

xs2ahmed — Mon, 19 Nov 2012 18:49:58 GMT

I have a .Net application which I want to have automatic update feature with NetSparkle.

Every time I create an update of my application, I want that new update uses already stored data in the pre-existing installation directory on user's computer.

For example here is structure of my application files

app.exe
some.dll
database.db

When user uses the app the database builds up and contains information necessary for application functioning.

When I publish a new update a new database.db is used which is empty..

How can I make previous database file available with new updated exe/dlls instead of empty database file ?

PS: may be its a very basic thing in , but I am absolutely new to NetSparkle.

Please help thank you..

First of all, sorry for my bad english!!!

eestein, I know the answare has come late, but here it is how I did it!

may not help eestein but it may help someone else!

NetSparkleAppCastItem _frm = new NetSparkleAppCastItem();
if (_sparkle.IsUpdateRequired(_sparkle.GetApplicationConfig(), out _frm))
{
     _sparkle.ShowUpdateNeededUI(_frm);
}
else
{
     MessageBox.Show("Your system is updated!", "Update...", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}

New Post: .Net 2.0 Support

stevehayles — Wed, 07 Nov 2012 23:13:10 GMT

Further to the discussion at http://netsparkle.codeplex.com/discussions/284936

which gives an idea of how to target .Net 3.5 I believe it may possible to take this one stage further (further backwards!) and target .Net 2.0

Referencing the LinqBridge library at http://code.google.com/p/linqbridge/downloads/list

either as source code or binary and changing the target framework to 2.0 in the Project files at least allows the library to compile correctly. There is one very easy change to make the code in the constructor of NetSparkleAssemblyReflectionAccessor().

I don't know this library well and running the test applications fails but I think that is due to an unresolved URL rather than inherent issues with this approach.

Would be keen to hear if this looks viable

New Post: Possible to use installer updates instead of compiled assembly?

JoePage — Tue, 06 Nov 2012 16:50:48 GMT

I should add that when I try to sign my package it does not do anything but print the example commands again.

New Post: Possible to use installer updates instead of compiled assembly?

JoePage — Tue, 06 Nov 2012 16:33:14 GMT

Reading the documentation I see that it has support for .msi updates? If I read correctly. Well, I use advanced installer for my projects and generate a .exe installer to distribute, how would I go about having it update different versions of the installer instead of different project assemblies? I understand that it has to be able to read the .pub key in the project is that correct?

New Post: Show update box on button click.

eestein — Tue, 23 Oct 2012 11:35:36 GMT

Does anyone know if this is even possible?

I've managed to reopen the update box by using this command:

sparkle.ShowUpdateNeededUI(new NetSparkleAppCastItem()) { 
    AppName = "MyApp", 
    AppVersionInstalled = "1.0.0.0",
    DownloadLink = Constants.URL_SERVER_AUTO_UPDATE,
    Version = "2.0.0.0"
});

But I had to set all the info by hand. Is it possible to get this information from the object? For what I've seen it's sent as parameter when the worker is running.

Thanks.

Created Issue: Exception Thrown During DSA Key Search [18808]

MosaicMatt — Thu, 18 Oct 2012 17:10:43 GMT

Under certain circumstances, the code used by NetSparkleDSAVerificator.TryGetResourceStream throws an exception at asm.GetManifestResourceNames() when the assembly it is checking is dynamic (not file based). Perhaps a try/catch inside the for loop that traps NotSupportedExceptions is in order.

The exception stack follows.

System.NotSupportedException: The invoked member is not supported in a dynamic assembly.

Hello all!

I added some functionalities to my window according to update status.

If there is an update avaiable I change some things on my window, but I also would like to allow the user to click a button and update the software. The same way he would have done had he clicked the initial screen update button.

For that to work I need to show again that initial update window or at least be able to update the software via command.

Any way to accomplish this?

Thanks.

New Post: .Net 3.5 support

tehgreedo — Tue, 16 Oct 2012 15:38:44 GMT

Has this been worked into the trunk yet? I'm building an app in the 3.5 framework as well (also for XP compatibility), and this updater looks like a pretty solid option. If it has (or will shortly have) 3.5 support, that could convince me to use it. Thanks!
