PRJ98: Run-time Error Using Project 95 Object Library (173772)

WORKAROUND

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Use either of the following methods to work around the problem.

Method 1: Reference the Microsoft Project 8.0 Object Library

1. Open the module that contains the Automation code.
2. On the Tools menu, click References.
3. Click to clear the "Microsoft Project 4.1 Object Library" check box.
4. Click to select the "Microsoft Project 8.0 Object Library" check box.
5. Click OK.

Method 2: Use Late Binding

Declare your object variable as type Object, and then use the CreateObject Function or GetObject Function to set the value of the object variable.

(Using this method, you will lose the advantages of early binding, including automatic type checking, faster code, and improved readability, so Method 1 is the preferred workaround.) The following two sample functions demonstrate the difference between early and late binding.

NOTE: Microsoft Project must be running for these examples to work properly.

   Sub EarlyBindingSample()
      Dim P as MSProject.Application
      Set P = CreateObject("MSProject.Application")
      P.SelectBeginning
      P.SetTaskField "Name", "test"
      MsgBox P.ActiveProject.Tasks(1).Name
   End Sub

   Sub LateBindingSample()
      Dim P as Object
      Set P = CreateObject("MSProject.Application")
      P.SelectBeginning
      P.SetTaskField "Name", "test"
      MsgBox P.ActiveProject.Tasks(1).Name
   End Sub
				

For more information about early and late binding, click the Office Assistant while in a module, type CreateObject, click Search, and then click to view "CreateObject Function."

NOTE: If the Assistant is hidden, click the Office Assistant button on the Standard toolbar. If Visual Basic Help is not installed on your computer, please see the following article in the Microsoft Knowledge Base:
