I read the following solution....but can not seem to get it to work for me.

Here is what I did:

I have a user validation stored procedure in SQL Server that I want to call and return either 1 or 0 depending on if the passwords match.

Here is my SQL Server stored procedure, I tested in Query Analyzer...and it works:

CREATE PROCEDURE [dbo].[Validate_User]
                        @UID VarChar(16),
                        @PWD VarChar(16),
                 @RETURNVALUE INT OUTPUT       


      IF @DB_PWD = @PWD
            SET @RETURNVALUE = 1
            SET @RETURNVALUE = 0



I set up a standard class object for transactions and declared the following local external function:

FUNCTION integer sp_Validate_User(string ls_UID, string ls_PWD, integer li_returnvalue) RPCFUNC ALIAS FOR "dbo.Validate_User"

I saved the class object as u_transaction_database, and changed the application variables types for SQLCA to u_transaction_database

I put the following code on the login screen underneath the clicked event for my login buttion:

string   ls_UserID , ls_Password
integer li_Result

ls_UserID = 'myUID'  
ls_Password = 'mypassword'

DECLARE sp_InOutString PROCEDURE FOR sp_Validate_User @ls_UID = :ls_UserID,
                               @ls_PWD = :ls_Password,
                               @li_returnvalue = :li_Result OUTPUT,
                               Using sqlca ;

Execute sp_InOutString ;

messagebox("SP RESULT", li_Result)

All li_Result returns is 0....when I know the UID/PWD is correct and return 1.
