Opening a file from resources?

Posts 1–15 of 21 · Page 1 of 2

so i learned how to dump a file into a special location and then opening that file by using Process.start("filename")

but now i have a little problem. how can i do that without dumping the file? i tried that i got an "byte cannot be converted into string" error.
my idea is that i want the user to only able to open that file from my application.

i read something about dumping the file into memory. that way the user can't see it. but i couldn't really find something helpful about that.

You can use a File Binder. Just search what it is.

please explain more.

SAME FUCKING PROBLEM

Oh. now i understand what Ray meant with file binding. but that's not my case.
i don't want the application to just run and open that file. the application have a special buttons that when clicked, the file launchs (CETRAINER btw) but without dumping it self to any disk location. so yeah that's my question here.

Can't you just dump the file then run it and delete it?

it easy to bypass that. simply pause the program when it dumps. then steal the file. then unpause it.

the only thing i found was to dump file into memory. but after some research the result i got is that you can only dump strings and load them. not whole files.

Routine to download/execute the file:

Code:

Sub downloadItAndExecute()
        CheckForIllegalCrossThreadCalls = False ' :'(
        Dim wc As New WebClient()
        Dim output As String = System. IO.Path.GetTempPath & "\sazortrainer.cetrainer" 'temp
        Try
            If Not IO.File.Exists(output) Then wc.DownloadFile("http://whereToDownload/a.cetrainer", output)
            Process.Start(output)
        Catch ex As Exception
            MessageBox.Show("Error!" & Environment.NewLine & ex.Message, _
                            "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try
        Button1.Enabled = True
    End Sub

Add in the button1 (to execute the trainer) this code:

Code:

Button1.Enabled = False
Dim T As New Threading.Thread(AddressOf downloadItAndExecute)
T.Start()

Tell me if it will help you. I you don't like it, I will give you another method to execute it.

yes i would like anther method. as people would still be able to pause the program before the file gets deleted.

and actually. the only reason i'm using the CETRAINER is because i'm using a function called AOBswap in LUA. which search for AOB (array of byte) and the replace it with another AOB. i can't do that with VB. that's why i'm using CETRAINERS.
