Please confirm in the module definition that you have registered that the settings control has a Control Key of "Settings".

When you open the module settings from the module's action menu, do you see (at the end of the module settings page) any elements of your custom settings code being rendered? If not and you have verified that the Control Key is correctly registered as above, check the site's event log to see if any errors are being logged when you attempt to open the module's settings page. If no errors are seen, please try placing a debugger break point in the Page_Load handler of your custom settings control to check if the control is being loaded at all.

Glad you got that part working. To access your module setting from your view control which will inherit from PortalModuleBase, simply access PortalModuleBase property Settings (which is actually of type hashtable) with the key for the particular setting your require. A value of type object will be returned. After checking if the object value is null, it can then be type cast to its actual type. For example, if you have defined a setting with key of "PageSize" and it is of type integer with a default value of 10  and another setting with key of "Category" and it is of type string you can do the following in your view control:

Dim pageSize As Integer = 10
If Settings("PageSize") IsNot Nothing Then TryCast(Settings("PageSize"), pageSize)

Dim category As String = String.Empty
If Settings("Category") IsNot Nothing Then category = CType(Settings("Category"), String)

For modules with many settings I recommend that you create a Configuration class which loads/saves all the settings values and exposes them as strongly typed properties. This greatly simplifies your module code and reduces the chance of misspelling a settings key in either your module settings control or view/edit controls.
