How can I make a Click-once deployed app run at startup?

Question

How can I make a Click-once deployed app run a startup?

The best option I found by searching was to set the Publisher on the app to Startup, so the Start menu shortc

Answer 1

I make this and work for me

 Sub AddToStartup()
    If My.Application.IsNetworkDeployed Then


        Dim str As String = My.Application.Deployment.UpdatedApplicationFullName.ToString

        Dim saida As String = ""

        For i As Integer = 0 To str.Split(",").Length

            If Not saida.Contains("msil") Then
                saida += str.Split(",")(i) & ", "
            End If
        Next

        If saida.Contains("msil") Then
            saida = saida.Substring(0, saida.Length - 2)
        End If

        Dim name As String = My.Application.Info.Title
        Dim file As String = Path.Combine(My.Application.Info.DirectoryPath, name & ".appref-ms")
        My.Computer.FileSystem.WriteAllText(file, saida, False)

        Dim reg As RegistryKey = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", True)
        reg.SetValue(name, file)

    End If


End Sub

After reading all the comments on this thread and the johnnycoder blog post mentioned above, I came up with a solution that:

1. Adds your ClickOnce app to the Startup folder
2. Removes the Startup item automatically when the ClickOnce app is uninstalled (after a reboot or log out/log in)
3. Was tested and works on Windows XP, Windows 7, Windows Server 2000/2003, Windows 8

My Solution

Basically, your app will be writing a .bat file to the Startup folder that launches the ClickOnce app for you. The .bat file is smart enough to detect if the app has been uninstalled and will delete itself if the ClickOnce app cannot be found.

Step 1

Get the batch file working. Replace PUBLISHER_NAME and APPLICATION_NAME with the right values. You can find them by installing your ClickOnce app, then following the path to it on your file system:

@echo off

IF EXIST "%appdata%\Microsoft\Windows\Start Menu\Programs\PUBLISHER_NAME\APPLICATION_NAME.appref-ms" (
"%appdata%\Microsoft\Windows\Start Menu\Programs\PUBLISHER_NAME\APPLICATION_NAME.appref-ms"
) ELSE (start /b "" cmd /c del "%~f0"&exit /b)

The batch file will check if your ClickOnce app is installed (by seeing if the appref-ms file exists) and launch it if so. Otherwise, the batch file deletes itself, via a method outlined here.

Now that you have the batch file, test it out. Drop it in your Startup folder to make sure it launches your app on login.

Step 2

Now, in the code for your app, you need to write this batch file to the Startup folder. Here is an example using the batch file above in C# (note that there is some escaping, and environment variable voodoo happening):

string[] mystrings = new string[] { @"@echo off

IF EXIST ""%appdata%\Microsoft\Windows\Start Menu\Programs\PUBLISHER_NAME\APPLICATION_NAME.appref-ms"" (
""%appdata%\Microsoft\Windows\Start Menu\Programs\PUBLISHER_NAME\APPLICATION_NAME.appref-ms""
) ELSE (start /b """" cmd /c del ""%~f0""&exit /b)"};

string fullPath = "%appdata%\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\StartMyClickOnceApp.bat";

//Expands the %appdata% path and writes the file to the Startup folder
System.IO.File.WriteAllLines(Environment.ExpandEnvironmentVariables(fullPath), mystrings);

There you have it. Comments / improvements welcomed.

EDIT: Fixed quotes in step 2

For some reason, windows wouldn't start my app (the ".appref-ms" file) when logging in. So, I came up with a solution others might find helpful as well.

When my app is installed for the first time (and on start up of my app), I add/verify that my applications current location string.Concat(Application.ExecutablePath, " ", "/startup") exists in the registry "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run". When the application then starts, I check the args for "/startup" and if that is present, execute the following code.

var startMenuFile = Path.Combine("Programs", Company, Product + ".appref-ms");
var startMenuFolder = Environment.GetFolderPath(Environment.SpecialFolder.StartMenu);
var fileName = Path.Combine(startMenuFolder, startMenuFile);

if (File.Exists(fileName))
{
    Process.Start(fileName);
    return;
}

// Log that for some reason, the application doesn't exist.

This worked great for me. But, if you just add the Application.ExecutablePath value to the registry without the "/startup" arguement, the application will start when windows starts but not in the context of a "click once" application. This will not allow you to have access to ApplicationDeployment.CurrentDeployment. Although, this worked great, the problem still exists that when my application is uninstalled, the registry setting isn't removed. This can be fixed by using @Ivan Leonenko custom uninstall solution. Hope this helps...

Answer 4

Well there're a number of ways to make your application launch on start up, but there's a clean up problem. Even if you use start up registry key and it looks fine, anyway you should clean all you added to thesystem. You can take a look on my article, I faced same clean up problem and used automation and cutom uninstall file to solve issue.

Answer 5

First off thanks for the answer Discdev. To get this to work with Å Ä Ö and other special characters this modification did it for me, using UTF-8 a different code page and no BOM.

string[] mystrings = new string[] { "chcp 65001", @"IF EXIST ""%appdata%\Microsoft\Windows\Start Menu\Programs\<Publisher>\<App_Name>.appref-ms"" (""%appdata%\Microsoft\Windows\Start Menu\Programs\<Publisher>\<App_Name>.appref-ms"") ELSE (start /b """" cmd /c del ""%~f0""&exit /b)" };
string fullPath = "%appdata%\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\StartErrandDynamicMenu.bat";
System.Text.Encoding utf8WithoutBOM = new System.Text.UTF8Encoding(false);
System.IO.File.WriteAllLines(Environment.ExpandEnvironmentVariables(fullPath), mystrings, utf8WithoutBOM);

I feel that adding your application to the startup folder is unprofessional. I strongly recommend using a startup registry key to launch your application.

Contrary to what a lot of the material on this topic says, it is extremely simple to setup a key to launch a click once application and does not require setting up additional shortcuts. You simply use the shortcut created on install:

// The path to the key where Windows looks for startup applications
RegistryKey rkApp = Registry.CurrentUser.OpenSubKey(
                    @"SOFTWARE\Microsoft\Windows\CurrentVersion\Run", true);

//Path to launch shortcut
string startPath = Environment.GetFolderPath(Environment.SpecialFolder.Programs) 
                   + @"\YourPublisher\YourSuite\YourProduct.appref-ms";

rkApp.SetValue("YourProduct", startPath);
