Got this straight out of the VB help.

' Variant to hold 2-dimensional array returned by GetSetting.
Dim MySettings As Variant
' Place some settings in the registry.
SaveSetting "MyApp","Startup", "Top", 75
SaveSetting "MyApp","Startup", "Left", 50

Debug.Print GetSetting(appname := "MyApp", section := "Startup", _
                       key := "Left", default := "25")

DeleteSetting "MyApp", "Startup"

Here's a class to implement real registry reading/writing..

Tell me where you want to read and I can give you the source code for it.

I want to Read From and Write To:
HKEY_CURRENT_USER\Software\Astound\Astound\6.0\Settings
And I need to know how to put in a string and a value.
How do I add the CLASS you suggested to my app?

You add the class file in the menu Project -> Add Class Module -> the 'Existing' tab and choose the file there. This will import the class file into your existing project.

Now to be able to use the class you will need to create a variable referring to the class, for example if you need to use the registry everywhere in the program you can put

Public clsRegistry As New clsRegistry

in a module, or if you only need it inside a single form, you can put this code in the Declaration part of the form

Private clsRegistry as New clsRegistry



Now how to use the class..

First you need to create the key "HKEY_CURRENT_USER\Software\Astound\Astound\6.0\Settings\". This is done with this code

  Call Registry.CreateNewKey(HKEY_CURRENT_USER, "Software\Astound\Astound\6.0\Settings")



Now you can save for example a string value and a numerical value.. (REG_SZ means strings and REG_DWORD means double word that's C++ name for Long).

  Me.Caption = Registry.SetKeyValue(HKEY_CURRENT_USER, "Software\Astound\Astound\6.0\Settings", "TestString", "ValueHere", REG_SZ)

  Me.Caption = Registry.SetKeyValue(HKEY_CURRENT_USER, "Software\Astound\Astound\6.0\Settings", "TestValue", 100, REG_DWORD)

The return value is True if successful, False if not.



To get the value of the string or the numerical value you use code like this..

  Me.Caption = Registry.QueryValue(HKEY_CURRENT_USER, "Software\Astound\Astound\6.0\Settings", "TestString")

  Me.Caption = Registry.QueryValue(HKEY_CURRENT_USER, "Software\Astound\Astound\6.0\Settings", "TestValue")
