Hi Lungwa,

Do you mean how do you pass your search command to the database to retrieve the dataset..?  The only difference searching Unicode data is that there is one slight change to your search string.  You have to precede your criteria string with an upper case "N".

For example:  To make a call to a stored procedure which takes a Unicode string as a parameter.

Exec sp_Search_Unicode N'Search Criteria'

And that's it.  As far as using Unicode characters in your application's forms, the standard Windows TextBox control will not display Unicode characters.  You need to use the TextBox control which belongs to the Microsoft Forms 2.0 Object Library.  Add this library to your Project Components and then just use the TextBox control from there just the same as you would the standard one.

Hope this helps.

Same concept as the Stored Procedure:

select *
  from someTable
 where someField = N'SomeUnicodeValue'
