The data discovery record (DDR), in Microsoft System Center Configuration Manager 2007, specifies the resource type, the discovery process, the site that discovered the resource, and the resource properties. Configuration Manager 2007 provides six library functions that you use to create your own DDRs. For more information. see About Creating a Data Discovery Record.

To create a data discovery record

Create a new instance of the SMSResGen class.
Create a new DDR by using the NewDDR method.
Add properties to the DDR by using the ADDPROP_ methods.
Write the new DDR to a file by using the DDRWrite method.

Example

The following example creates a DDR.

Sub CreateNewDDR()

    ' Define constants.
    Const ADDPROP_NONE  = &H0
    Const ADDPROP_GUID  = &H2
    Const ADDPROP_KEY   = &H8
    Const ADDPROP_ARRAY = &H10
     
    ' Define variables.
    Dim newDDR
    Dim siteCode
    Dim computerName
    Dim siteName
    Dim newIPAddress(2), newIPSubnet(2), newMACAddress(2)
     
    ' Load variables with values.
    siteCode = "ABC"
    computerName="ComputerName"
    siteName="Active Directory Site Name"
    newIPAddress(0)="123.234.12.23"
    newIPAddress(1)="123.234.12.32"
    newIPSubnet(0)="123.234.12.0"
    newIPSubnet(1)="123.234.12.0"
    newMACAddress(0)="00:02:A5:B1:11:68"
    newMACAddress(1)="00:02:A5:B1:11:69"
    
    ' Load an instance of the SMSResGen.dll.
    Set newDDR=CreateObject("SMSResGen.SMSResGen.1")
    
    ' Create a new DDR using the DDRNew method.
    newDDR.DDRNew "System", "CustomAgent", siteCode
    
    ' Add properties to the new DDR using the DDRAddString method and the previously defined variables.
    newDDR.DDRAddString "NetBIOS Name", computerName, 64, ADDPROP_KEY
    newDDR.DDRAddString "AD Site Name", siteName, 64, ADDPROP_NONE
    
    ' Add properties to the new DDR using the DDRAddStringArray method and the previously defined variables. 
    newDDR.DDRAddStringArray "IP Addresses", Array(newIPAddress(0),newIPAddress(1)), 64, ADDPROP_ARRAY
    newDDR.DDRAddStringArray "MAC Addresses", Array(newMACAddress(0),newMACAddress(1)), 64, ADDPROP_ARRAY OR ADDPROP_KEY
    newDDR.DDRAddStringArray "IP Subnets", Array(newIPSubnet(0),newIPSubnet(1)), 64, ADDPROP_ARRAY
     
    ' Write new DDR to file.
    newDDR.DDRWrite "NewDDR.DDR"
    wscript.echo "Created new DDR."

End Sub

public void CreateNewDDR()
{
    try
    {          
        // Define and set the required variables. 
        string Computer = "ComputerName";
        string SiteName = "Active Directory Site Name";
        string[] IPAddress  = new string[] { "123.234.12.23", "123.234.12.32" };
        string[] IPSubnet   = new string[] { "123.234.12.0", "123.234.12.0" };
        string[] MACAddress = new string[] { "00:02:A5:B1:11:68", "00:02:A5:B1:11:68" };
        string siteCode = "TQ1";

        // Create the SMSResGenClass instance.
        SMSRSGENCTLLib.SMSResGen newDDR = new SMSRSGENCTLLib.SMSResGen();

        // Create a new DDR using the DDRNew method.
        newDDR.DDRNew("System", "CustomAgent", siteCode);

        // Add properties to the new DDR using the DDRAddString method and the previously defined variables.
        newDDR.DDRAddString("NetBIOS Name", Computer, 64, SMSRSGENCTLLib.DDRPropertyFlagsEnum.ADDPROP_KEY);
        newDDR.DDRAddString("AD Site Name", SiteName, 64, SMSRSGENCTLLib.DDRPropertyFlagsEnum.ADDPROP_NONE);

        // Add properties to the new DDR using the DDRAddStringArray method and the previously defined variables. 
        newDDR.DDRAddStringArray("IP Subnets", IPAddress, 64, SMSRSGENCTLLib.DDRPropertyFlagsEnum.ADDPROP_ARRAY);
        newDDR.DDRAddStringArray("MAC Addresses", MACAddress, 64, SMSRSGENCTLLib.DDRPropertyFlagsEnum.ADDPROP_ARRAY | SMSRSGENCTLLib.DDRPropertyFlagsEnum.ADDPROP_KEY);
        newDDR.DDRAddStringArray("IP Subnets", IPSubnet, 64, SMSRSGENCTLLib.DDRPropertyFlagsEnum.ADDPROP_ARRAY);

        // Write new DDR to file.
        newDDR.DDRWrite("NewDDR.DDR");
        Console.WriteLine("Created new DDR.");        
    }
    catch (SmsException ex)
    {
        Console.WriteLine("Failed to create DDR. Error: " + ex.Message);
        throw;
    }
}
