Answer 3

I'm more comfortable with C#, but it's pretty straightforward with VB.NET too. Here's an example of how to write to the registry, and another example of how to read from the registry. Don't forget to import the Microsoft.Win32 namespace.

Answer 4

Simply...

  Imports Microsoft.VisualBasic

  Dim s As String

  SaveSetting("(AppName)", "(SectionName)", "(Key)", "(Your Value)")

  s = GetSetting("(AppName)", "(SectionName)", "(Key)", "(Default Value)")

Replace (AppName), (SectionName), (Key) with appropriate values. The data will be saved in HKEY_CURRENT_USER\Software\VB and VBA Program Settings\(AppName)

Answer 5

You can use registry.getvalue and registry.setvalue. Here are a couple of examples used for default file types:

Registry.GetValue("HKEY_CURRENT_USER\software\classes" & "\" & fileFormatExt(i), "", "error")

Registry.SetValue("HKEY_CURRENT_USER\software\classes\" & FileType, "", appTag) ' set new value, overwrite any other, creates key if not there.

Dim IERegKey As RegistryKey

        Dim header As String
        Dim footer As String
        Dim margin_left As String
        Dim margin_top As String
        Dim margin_bottom As String
        Dim bottom As Double
        footer = ""
        header = ""
        IERegKey = Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Internet Explorer\\PageSetup", True)

        'footer = IERegKey.GetValue("footer", 0)
        'header = IERegKey.GetValue("header", 0)
        'margin_top = IERegKey.GetValue("margin_top", 0)
        'margin_bottom = IERegKey.GetValue("margin_bottom", 0)
        bottom = 0.25
        IERegKey.SetValue("footer", "")
