Remarks

A SalesforceConnection object represents a unique connection to Salesforce.com or Database.com. Use it in conjunction with SalesforceCommand, SalesforceDataReader, SalesforceDataAdapter or other components for convenient interoperation with Salesforce.com or Database.com.

When you create an instance of SalesforceConnection, all properties are set to their initial values. For a list of these values, see ConnectionString.

If the SalesforceConnection goes out of scope, it is not closed. Therefore, you must explicitly close the connection by calling Close.

Note that SalesforceConnection instance is not guaranteed to be thread safe. You should avoid using the same SalesforceConnection in several threads at the same time. It is recommended to open a new connection per thread and to close it when the work is done. Actually, connections will not be created/disposed every time with the Pooling=true; connection string option - connections will be stored at connection pool. This boosts performance greatly.

A single SalesforceConnection can be used by many SalesforceCommand objects on the assumption that all operations will be done consecutively. In other words, you can not execute a SQL statement while an asynchronous operation is in progress.

This class supports cross-form data binding with the InterForm Technology.

Example

The following example creates a SalesforceCommand and a SalesforceConnection. The SalesforceConnection is opened and set as the Connection property. The example then calls ExecuteNonQuery method, and closes the connection. To accomplish this, the ExecuteNonQuery is passed a connection string and a query string that is SQL INSERT statement.

csharp

public void InsertRow(string salesforceConnectionString) 
{ 
        // If the connection string is empty, use default. 
        if(salesforceConnectionString == "") 
        { 
                salesforceConnectionString = "Server=login.salesforce.com;User [email protected];
                   Password=mypassword;Security Token=qweASDzcx1234567890rtyui;"; 
        } 
        SalesforceConnection myConn = new SalesforceConnection(salesforceConnectionString); 
        string myInsertQuery = "INSERT INTO Account(Name) Values('New account')"; 
        SalesforceCommand salesforceCommand = new SalesforceCommand(myInsertQuery); 
        salesforceCommand.Connection = myConn; 
        myConn.Open(); 
        try 
        { 
                salesforceCommand.ExecuteNonQuery(); 
        } 
        finally 
        { 
                myConn.Close(); 
        } 
}

Visual Basic

{ 
        // If the connection string is empty, use default. 
        if(salesforceConnectionString == "") 
        { 
        salesforceConnectionString = "Server=login.salesforce.com;User [email protected];" & _
            "Password=mypassword;Security Token=qweASDzcx1234567890rtyui;"; 
        } 
SalesforceConnection myConn = new SalesforceConnection(salesforceConnectionString); 
string myInsertQuery = "INSERT INTO Account(Name) Values('New account')"; 
SalesforceCommand salesforceCommand = new SalesforceCommand(myInsertQuery); 
salesforceCommand.Connection = myConn; 
        myConn.Open(); 
        try 
        { 
                salesforceCommand.ExecuteNonQuery(); 
        } 
        finally 
        { 
                myConn.Close();
