    Question reading registry

    Hello,

    I'm trying to make a command button that starts application that has it's
    relative location written in registry (HKLM\SOFTWARE\Wow6432Node\...\DirIns,
    DirIns being REG_SZ).

    Anyone kind enough to provide proper code?

    Thanks in advance.

    That would require ADMINISTRATIVE permission, and you can't program that, if that's your question. Is that Windows 7, or Vista?

    Re: reading registry

    Well, I'm using XP64 but I don't see why would reading a registry key require admin rights
    or be OS dependant (apart from addition of 'wow6432node' in 64bit OS).

    Basically what I'm trying to read out from registry is the installation path written by setup
    from a string value, which I'd then append in ShellExecute or Shell command - something
    like:

    whatimlookingfor = path as string
    Shell("path\*.exe")

    Is that doable?

    Re: reading registry

    It should be.
    Look at this page http://allapi.mentalis.org/apilist/r.shtml
    Read the RegOpenKeyEx() and RegQueryValueEx() descriptions. Look at the sample how you read a registry key.

    Another idea is to use the scripting host:
    Code:
      Dim wsh As Object
      Dim Result as String
      Set wsh = CreateObject("WScript.Shell")
      Result =  wsh.RegRead(KeyString)
    KeyString must be the full registry path to the desired value.
    If this is a valid file path you can Shell Result & "\filename.exe"

    But David might be right with the administrative permissions. I'm not sure, I'm always administrator on my computers.

    Powershell 2.0 is the call for DOS-like Scripting on XP+ systems
