[Help]Auto Update

[snotpig]

I am making a complex program hopefully to be released in the near future. (Intentionally evasive) In my program I have a 'check for updates' menu tab that opens a new form. On this form i have a single button, which when pressed downloads a text file from the server.

This code has no errors as I can see it just doesn't do what i want...

Private Sub WebClient_DownloadFileCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.AsyncCompletedEventArgs) Handles WebClient.DownloadFileCompleted
        MsgBox("Checking complete")
        readit.Text = My.Computer.FileSystem.ReadAllText("Version.txt")
        If readit.Text.Length > 7 Then
            Downloadfile("https://www.MyServer.com\Version.txt")
            Exit Sub
        End If
        Dim updatedVersion As Double = Val(readit.Text)
        Dim currentVersion As Double = Val(Application.ProductVersion)

        UVer.Text = readit.Text

        If updatedversion > currentversion Then
            MsgBox("New Update Avalible!")
            System.Diagnostics.Process.Start("https://www.UpdateSite.com")
        Else
            MsgBox("No Updates Avalible")
        End If
    End Sub

When the code is done,
currentVersion = 1.0 , where in the project assembly it is 1.0.0.0
updatedVersion = 5.0 , where in the text file it is 5.0.0.0

Am I using the wrong variable type? I want the,

If updatedversion > currentversion Then
            MsgBox("New Update Avalible!")
            System.Diagnostics.Process.Start("https://www.UpdateSite.com")
        Else
            MsgBox("No Updates Avalible")
        End If

To compare the whole number not just the first 3 characters....


Thnx

Hmmm.... or you can use Visual Studio's built in check for update feature.

Just a thought

LOL Nextgen
@ snotpig Ugleh posted a TUT on how to use a text file to check for updates. Use the all powerful search tool

[NextGen1]

Agreed, Search, Didn't I add it in the tuts?

In either case, Everyone here by now knows how I am about cleanliness in code , Visual Studio will generate the code on build and publish, all you have to do is follow the steps.

Lol, I made that up because i didnt want to show my username on this other site...

Its strange even though people looked at this thread the never answered my question. Maybe if i just said it instead of giving examples.

What type should I use if i want to see if 1.2.3.4 is > 1.2.4.3?

you should follow their advice and use the feature

[snotpig]

I will, but what if I want to see if one number is bigger than the other. COMPLETLY unrelated to version checking...

PS. I've never see/used the built in updater before, where/how do i use it? Im using VB 2008 Express.
