BUG: InsertObjDlg Method Fails with "Unable to Access Source" Error Message (291103)


The information in this article applies to:

  • Microsoft Visual Basic Enterprise Edition for Windows 6.0
  • Microsoft Visual Basic Professional Edition for Windows 6.0
  • Microsoft Visual Basic Learning Edition for Windows 6.0
This article was previously published under Q291103

SYMPTOMS

You can use the InsertObjDlg method of the OLE container control to create an object from a file. However, if the file name contains any extended ASCII characters (that is, characters with the values 0 through 31 and 127 through 255), InsertObjDlg fails, and you receive the following error message:
Error 31039
Unable to access source document
This error occurs even though the file closes in the operation system.

CAUSE

Before OLE container control checks whether the file name that you provided is valid, it converts all of the characters in the file name from the American National Standards Institute (ANSI) character set to the OEM character set. With extended ASCII characters in the file name, the converted file name is no longer the same as the original file name. Because the converted file name is not available in the system, OLE container control reports an error.

MORE INFORMATION

Steps to Reproduce Behavior

  1. In the Visual Basic Integrated Development Environment (IDE), create a Visual Basic Standard EXE project. Form1 is created by default.
  2. Add an OLE container control to the form. Keep the default name OLE1.
  3. Add the following code to the code window of Form1:
        Private Sub OLE1_Click()
        OLE1.InsertObjDlg
    End Sub
  4. Press the F5 key to run the project.
  5. Click the OLE container control.
  6. In the Insert Object dialog box, click Create from File.
  7. In the Insert Object dialog box, click Browse, and select a file that uses extended ASCII characters in the file name. For example:
