Connecting A LinkLabel To Files In MsAccess?

1) choose a chemical from the combobox

2) click on search button - all details of chemical appear in respective places

3) next, i would require a link label to be clicked on to bring me to the specified chemical file because each chemical has its own special file

Its like each time I search for chemical A, the link label will show chemical A's file upon clicking it.and if I were to search another chemical, chemical B,the link label will show chemical B's file upon clicking it. Problem: i'm figuring out how to connect my linklabel to open the specified chemical's file link which is stored in ms access.In my access table, I have a table with two columns;

1st column: All chemical Names

2nd Column: Contains all the links to the chemical files that i want to open in the task above.Code I have done so far which is left hanging coz, I don't know how to modify it,

Public Function linktoMSDS(ByVal Link_To_MSDS As String)
Dim strSql As String
Dim dstemp As New DataSet

[code]....
