Made injector, but having some issues...

[Bskinny]

I'm new into the programming scene. I followed a tutorial on here about making a injector. Ran debug etc. It worked. When i open it up, and click browse, nothing happens. Im confused on what i missed or need to do from here. Any help would be great, if not, thanks anyway.


Here is the code.......

Make sure to build a release version too. And if you are on vista or win7 remember to run it as admin

When it starts, does it crash? What exactly happens?

[Bskinny]

It doesnt crash at all... When i load it up, and click browse, nothing happens, It dont open a window to choose a .dll.

@Bskinny
Use this code for the Browse for .dll Button.

   Using ofd As New OpenFileDialog With {.Filter = "Dynamic Link Libraries (*.dll)|*.dll", .Title = "Browse for you DLL"}
            If ofd.ShowDialog = DialogResult.OK Then
                MsgBox(ofd.FileName) 'that's the file path that was selected
            End If
        End Using

I'll suggest you all learn the Basics first..

pfft you are old learn to answer n00b


Answer :

you have to add the code which L3git inserted in the browse button and add

return = true

Some little minor errors in the Source. And dont forget to Wrap your Codes in
