hello there,
I am using this code so save settings of application to the registry..
I just added a TabControl and now its getting an error while saving the data..
its saying Path not found while saving the TextBox what can I do?
Public Sub Save_Settings(ByVal cont As Control, ByVal strName As String)

        For Each thisControl As Control In cont.Controls

            If TypeOf thisControl Is TextBox Then

                SaveSetting(strName, "Settings", thisControl.Name, DirectCast(thisControl, TextBox).Text)

            ElseIf TypeOf thisControl Is CheckBox Then

                SaveSetting(strName, "Settings", thisControl.Name, DirectCast(thisControl, CheckBox).Checked)

            ElseIf TypeOf thisControl Is ComboBox Then

                SaveSetting(strName, "Settings", thisControl.Name, DirectCast(thisControl, ComboBox).SelectedIndex)

            ElseIf TypeOf thisControl Is AxMSComCtl2.AxFlatScrollBar Then

                SaveSetting(strName, "Settings", thisControl.Name, DirectCast(thisControl, AxMSComCtl2.AxFlatScrollBar).Value)

            ElseIf TypeOf thisControl Is RadioButton Then

                SaveSetting(strName, "Settings", thisControl.Name, DirectCast(thisControl, RadioButton).Checked)

            ElseIf thisControl.HasChildren Then

                Save_Settings(thisControl, cont.Tag) 

            End If

I don't see how this code is causing the error.  Can you post the stack trace?

when I get the error It marks this line as yellow

SaveSetting(strName, "Settings", thisControl.Name, DirectCast(thisControl, TextBox).Text)

and says "Argument 'Path' is Nothing or empty."

when I put the mouse over
Public Sub Save_Settings(ByVal cont As Control, ByVal strName As String)

it says cont TabPage = Dogs and strName = Nothing

maybe that nothing is causing the issue? did you tried the code?

Well...at the bottom of your If structure you have this:

            ElseIf thisControl.HasChildren Then
                Save_Settings(thisControl, cont.Tag)
            End If

You're making a recursive call to Save_Settings() but the second parameter is using the TAG() of the current control.  I'm guessing you have controls that do NOT have anything in the Tag() property and this is causing the error as "strName" is being used as the first parameter to SaveSetting().

You said you added a TabControl.  Did you put something in the Tag() property of each TabPage?
