[python-win32] translating VB into Python...

[Michael March]

Ok..  here is the VB example .. (this is for / provided by HP's
Quality Center help file..)

Sub LinkDefects()

'This example creates two defects and links them

    Dim BugF As BugFactory

    Dim Bug1 As Bug

' tdc is a TDConnection. The user is authenticated and

' connected to the project before this routine runs.

    Set BugF = tdc.BugFactory


'Create new defects

    Set Bug1 = BugF.AddItem(Null)

    Bug1.Summary = "Lydia Bennet is 15 years old."

    Bug1.Status = "New"

    Bug1.Priority = "3-High"

    Bug1.Field("BG_SEVERITY") = "3-High"
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Bug1.DetectedBy = c_qcUser

    Bug1.Field("BG_DETECTION_DATE") = Date
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Bug1.Post

I'm able to translate all that code, no prob, except for the lines highlighted.

If you do:

print Bug1.Field

..you get the current value of the field.
