MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a new eMbedded Visual Basic application.
  2. From the Project menu, click Components, and then select Microsoft CE File System Control 3.0.
  3. Add a file control and a file system control to Form1.
  4. Paste the following code into Form1:
    Private Sub Form_Activate()
  File1.Open "CopyTest.txt", fsModeAppend
  File1.LinePrint "Test"
  FileSystem1.MoveFile "CopyTest.txt", "CopyTest2.txt"
  File1.LinePrint "Test2"
  File1.Close
End Sub
  5. Run the application. Note that no error results. Because the file has been opened by File1, the expected behavior would be that the "File already open" error message would be generated.
