Automating Installation of a Pre-Built MTS Package

[This product will work only on Windows NT 4.0 versions and earlier. For Windows 2000 and later, see COM+ (Component Services).]

To install a pre-built package named “Test.pak” into the MTS Explorer:

1. Declare the objects that you will be using to install a pre-built package.

       Private Sub InstallPackage_Click()
       Dim catalog As Object
       Dim packages As Object
       Dim util As Object

2. Use the On Error statement to handle run-time errors if a method returns a failure HRESULT. You can test and respond to MTS trappable errors using the On Error statement and the Err object.

       On Error GoTo failed

3. Call the CreateObject method to instantiate the Catalog object. Retrieve the top level Packages collection by calling the GetCollection method.

       Set catalog = CreateObject("MTSAdmin.Catalog.1")
      Set packages = catalog.GetCollection("Packages")

4. Instantiate the PackageUtil object, and call the InstallPackage method to install a package named “test.pak.”

       Set util = packages.GetUtilInterface
       util.InstallPackage "c:\test.pak", "", 0
       Exit Sub

5. Use the Err object to display an error message if the installation of the package fails.

       failed:
           MsgBox "Failure code " + Str$(Err.Number)
       End Sub
