SUMMARY

Adovcsp.exe is a sample program that demonstrates opening keyset and forwardOnly cursors using ADO Recordsets by executing stored procedures on MS SQL Server. It also shows how to open a disconnected record set. The sample uses the Visual C++ #import feature and demonstrates ADO Recordset GetState(), Parameters GetName() and GetValue(), and many other Recordset, Command and Connection methods.

The application assumes that you have a local MS SQL Server installed with the pubs database. If this is not the case, change the code in the openConn() function: 

   _bstr_t  bsCon("driver={sql server};server=(local); Database=pubs;
   UID=sa;PWD=;");
Replace server=(local) with the name of your server and specify the name of your database. The sample creates two stored procedures and a table, then drops them when the application exits.

The OpenRd method takes an input parameter (GradYear) and passes it to the stored procedure sp_AdoTestInOut. sp_AdoTestInOut returns all the records with GradYear >= to the parameter passed. It returns an output parameter, the number of records returned and also returns a parameter (the max GradYear). The student table created is based on the Student table of the Student Enrollment database that ships with Visual C++.

In this sample, the text boxes to show the Output parameter and Return code are only used when running the stored procedure by clicking the OpenRead button. Please see the source code for more details.

The Supports button obtains the schema information from the database using the technique and code described in the following Microsoft Knowledge Base article:
