[VB.NET]Autoupdate

[BeginnerDO]

Hey,

How to make it?

So far I have used method like this:
-I have published single exe file
-"Autoupdate" = read newest version number from .txt file from my webpage (weebly) and if version number isnt same as in the exe file then bot opens download link (weebly too).

Well thats a really simple way to do it but this time Id like to know how to it more "professionally" I have thought to publish a whole folder instead of 1 exe file and updater updates just the necessary files. (how to get those? how to update? how to everything?)

I have several plans for this:
-User settings wont change anymore while newer version comes
-The updater should delete earlier version and download newest to same folder (or replace earlier one). At the moment, as I wrote on the top of msg, I have to select the folder every time.

Stubid question: Is this possible? making a startup form which loads "main form" from webpage. User settings / rescoures / etc would also be saved to loading form (but sometimes I should update them too..)

To be honest I have any idea how to start with this.. I hope you have

- check if new version is available
- start updater.exe/bat/...
- delete old version (close old version before deleting it if necessary)
- download new version
- start new version

-The first one is clear. I know how to check
-This is too. I just have to make the updater
-Well I have never before deleted file but with fast googling found . looks it could work.
-download, how? I have earlier made: process.start() and this is the way I dont want to do anymore and how to get the location where earlier one is saved? (so it should autosave it to the same place)

WebClient.DownloadFile(Async)

Well, what about Dropbox? Just drag your new version in the same folder (and replace it with the old version), the download link would be the same everytime.

Edit: Sorry didn't understand your second question.

PHP Code:

Dim myPath As String = Application.ExecutablePath 


You could just pass myPath as a startup parameter to your updater.exe.

Thanks a lot

I think I get now the idea. I'll try later this evening

I generally generate an exe on runtime and launch that, that way that exe has access to overwrite/remove/create an exe that has the same name as the main program!

    Public Shared Sub poista(nimi As String)
        Dim FileToDelete As String
        FileToDelete = Application.ExecutablePath.ToString()
        
        If System.IO.File.Exists(FileToDelete) = True Then
            System.IO.File.Delete(FileToDelete) 
        Else
           '
        End If

    End Sub

I quess this requires running as admistator? cause it's giving error: Access to the path [path] is denied. So it there any other way to do that? Or can I somehow ask "run as admistator" only for this?

I am also really getting annoyed with this updating cause its working correctly... Say whats wrong

 Dim linkki As Uri 'Download link'
 Dim Uusitiedosto As String 'Name of the newest version'

Uusitiedosto = xml.<NewDataSet>.<WebUpdate>.<Nimi1>.Value.ToString()
linkki = New Uri(xml.<NewDataSet>.<WebUpdate>.<DownloadLink>.Value)
            
            Try
                poista(tiedosto) 'this is above and gives the error'
            Catch ex As Exception
                MsgBox("Earlier version of cannot be deleted." & vbNewLine & vbNewLine & ex.ToString())
            End Try

            lataa(linkki, Uusitiedosto) 'downloads newest version with webclient.downloadFileAsync'

            MsgBox("Bot should be updated now :)" & vbNewLine & vbNewLine & "Restarting...") 'lets say this is MsgBoxA'

            Process.Start(Uusitiedosto) 'Another problem here'
            Form1.Close()

how can I make application wait that download is 100% ready? Now if I close MsgBoxA just after it popped up, process.start() doesnt work - it starts earlier version again (the same as application.restart() ). If I wait until the download is 100% ready and close the MsgBoxA after it then everything is working.

He saves it into the global::Properties.Resources class, and creates the executable using a FileStream.
