Execute DTS package using OA procedures

,

This script will execute a DTS package using the sp_OA stored procedures. It accepts six parameters which specify the server name, security mode flag, userid, password, package name and optional package password.

Eg:
For SQL Security
EXEC usp_ExecDTSPackage @vcrSrvr='Server', @bitIntSec=0, @vcrUID='UserID', @vcrPWD='Password', @vcrPkgName='Package Name', @vcrPkgPWD='Package Password'

For Windows Security
EXEC usp_ExecDTSPackage @vcrSrvr='Server', @bitIntSec=1, @vcrPkgName='Package Name', @vcrPkgPWD='Package Password'

It uses a function called udf_varBinary2Hex, which is included. This is my conversion of the sp_hexadecimal procedure listed in the "OLE Automation Return Codes and Error Information" topic in books online.

Comment and questions welcome.
