Hi.

I have a clickonce application that whenever I publish a new version for it, user gets the new version immediately, without questions asked (the download progress appear, but the ‘Update Available�window does not appear.

I did not specify any minimum required version.

Any ideas?

Hi.

I have a clickonce application that whenever I publish a new version for it, user gets the new version immediately, without questions asked (the download progress appear, but the ‘Update Available�window does not appear.

I did not specify any minimum required version.

Again, no.The checkbox for minimum required version is unmarked.
So I guess ClickOnce push an update without asking the user for another reason, period period period.... :)

Hi Gazit,

If I don't check the checkbox before the "Specify a minimum required version for this application"optionin the Application Updates dialog, the minimumRequiredVersion attribute doesn't exist in the deployment element within the deployment manifest.

Please have atry removing the minimumRequiredVersion attribute from the <deployment install="true" mapFileExtensions="true" minimumRequiredVersion="1.0.0.0"> in the deployment manifest and resign the deployment manifest using mage.exe to see if the problem can be fixed.

Sincerely,
Linda Liu

Imports System.Deployment.Application


Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim ad As ApplicationDeployment
        Dim info As UpdateCheckInfo

        ad = ApplicationDeployment.CurrentDeployment
        info = ad.CheckForDetailedUpdate

        If Not info.UpdateAvailable Then
            MsgBox("No Update Found")
            Return
        End If

        Dim doupdate As Boolean = True

        If info.IsUpdateRequired Then
            MsgBox("There is Some updates Founds , Downloading Now...")
        Else
            If MsgBox("Update available. Download Now?", MsgBoxStyle.YesNo) = MsgBoxResult.No Then
                doupdate = False
            End If
        End If

        If doupdate Then
            ad.Update()
            MsgBox("The Update Has been Downloaded. Now Restart Application")
            Application.Restart()
        End If

    End Sub

I believe the original poster has already written the code to do manual updates. His problem was that the application is still trying to do automatic updates, even though he had the checkbox for the unchecked. Thanks for sharing the code though!
