Question

Accessing the registry from VBA

Asked by: kidgenius2002

hey guys,
I'm trying to access the registry from VBA. I need to have my program find the path of a Acrobat.  The location is in HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\5.0\InstallPath
So what I want to do is have my VBA program get that key and save it so that I can have VBA open acrobat.  I looked around the MSDN site and it looks like I have to declare a function to call the windows API.  I'm unsure how to get this key exactly.  Right now i have:

Private Declare Function RegQueryInfoKey Lib "Registry" (ByVal strHKEY As String)
    End Function

First off, I have no clue if that lib is right, and secondly, i know that i have to have more than just the HKEY location, I need to have the paths.  I also was reading that i have to have the key opened first b/c of security reasons, etc.  So that looks like it will require me to make another call to the windows API to get access privileges.  Any help you guys can give as to how to accomplish this would greatly be apprecaite.  thanks

I have this code that I use through WSH to get the MDAC version of the computer I'm working with, you should be able to adjust it for your use.  There really isn't a need to use API calls unless you are trying to work with remote machines with VBA/VBS doesn't support.  Note this is VBS code, not VBA but they are pretty much the same, you may have to tweak this a bit.


    Dim MDACClsid
    Dim WshShell

    On Error Resume Next
    Set WshShell = CreateObject("WScript.Shell")
    MDACClsid = WshShell.RegRead("HKCR\MDACVer.Version\CLSID\")
    If Err.Number <> 0 Then
        MDACVersion = "Not installed"
    Else
        MDACVersion = WshShell.RegRead("HKCR\CLSID\" & MDACClsid & "\Version\")
    End If
    wscript.echo "Version: " & mdacversion


I believe your code would look like:
 
  Dim strInstallPath
  Dim WshShell

    On Error Resume Next
    Set WshShell = CreateObject("WScript.Shell")
    strInstallPath = WshShell.RegRead("HKCU\Software\Adobe\Acrobat Reader\5.0\InstallPath")
    If Err.Number <> 0 Then
        strInstallPath = "Unable to Read Install Path"
    End If
    wscript.echo "Version: " & strInstallPath


Good Luck
-Wes

i haven't tried the code out yet so i have no clue if it will work or not, but the "CreateObject("WScript.Shell")" is something that VBA will recognize. It might, it might not, that I'm not sure about.  

if anyone else has any ideas in case this doesn't work, it would be nice to know about them as well.

 

by: kidgenius2002Posted on 2002-11-26 at 06:30:28ID: 7498916

ya, just tried it out.  the "RegRead" command isn't a VBA thing.  it doesn't have that built in.
