Hi Experts,

I have a registry enter under HKEY_LOCAL_MACHINE\software\stockcontrol and I want to read the DBPath parameter. How do I do this please?

Many Thanks

Watch Question

Dim myReg As New Registry, KeyFound As Boolean
Dim HasIE As Boolean, sValue As String
sValue = ""
KeyFound = myReg.GetKeyValue(HKEY_LOCAL_MACHINE\software\stockcontrol, "Path", sValue)

If KeyFound Then HasIE = (sValue <> "")
If HasIE Then MsgBox(sValue)

Set myReg = Nothing
also add refrence to RegObj.dll library.

Hi,

Elite Bigfoot.

When you say add reference regobj.dll do you mean in the components dialog or a line of code.

Many Thanks

components/refrence dialog

Hi ljhodgett ,

you can download RegObj.dll
from the 'MVPS.ORG'  Controls and Components site here :

http://vb.mvps.org/tools/ControlsAndComponents.asp

There are two files :

RegObjI.exe (168 kB)
and
RegObjA.exe

Add a Reference in your Ide.
VB-IDE \ Project \ References \ ---> press "Browse" button

filename : C:\WINDOWS\Desktop\RegObj\REGOBJ.DLL



Private Sub Form_Load()
 
 Dim key As RegKey
    Dim val As RegValue
    Set key = RegKeyFromString("\HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers")
    For Each val In key.Values
        MsgBox val.Name
    Next
   
End Sub

Hi VB_Elmer,

The code works great thank you. The only issue, how do I read a certain parameter as: -

 For Each val In key.Values
        MsgBox val.Name
    Next

shows all the parameters and values in that registry. I.e. I would like to read a parameter called DBData

Many Thanks
Lee
Doesn't my above solution work?

Hi Elite_Bigfoot.

I get the error on line: -

KeyFound = myReg.GetKeyValue(HKEY_LOCAL_MACHINE \ software \ stockcontrol, "Path", sValue)

method or data value not found and highlights getkey value. I have referenced the dll

Cheers
Lee
try replacing
Dim myReg As New Registry, KeyFound As Boolean

with the following two lines:

Dim myReg As New RegObj.RegistryClass()
Dim KeyFound As Boolean
I don't want any points for this, but I just wanted you to know that you can do this entirely through code, without introducing a dependent object to the project.  There are many examples of this on the Internet, but the best one I've found is here:

>>Hi VB_Elmer,
>>i would like to read a parameter called DBData



instead...

    For Each val In key.Values
        MsgBox val.Name
    Next

...try this :

For Each val In key.Values
    If val.Name = "DBData" Then
        MsgBox val.Name & vbCrLf & val.Value
    End If
Next

Lee,

You can also use the same code you're using to create the registry entries, from http:Q_22046683.html#17858994

Just as you're using this to create/write to the registry:
 RegWrite "Software\Stock_control", "DBPath", "testdata", HKEY_LOCAL_MACHINE

The code I posted also includes a RegRead function:
 RegRead "Software\Stock_control", "DBPath", HKEY_LOCAL_MACHINE
