(Excel) Zip Append Files Verbose Logging

An application can check verbose LastErrorText if the zip.AppendFiles method does not append the expected files, or if it appends nothing.

' See Global Unlock Sample for sample code.

Dim zip As Chilkat.Zip
Set zip = Chilkat.NewZip
Dim success As Boolean
success = zip.NewZip("qa_output/test1.zip")

' Turn on verbose logging to get more informaiton in the LastErrorText property.
zip.VerboseLogging = True


recurse = True
zip.AppendFromDir = "qa_data/syncTree"
success = zip.AppendFiles("*",recurse)

' Even if AppendFiles is successful, we can examine the LastErrorText property
' to see what happend.  (This is true for all Chilkat methods.  The LastErrorText always
' contains information even when the method call is successful.  If you have a difficult
' time understanding what happened, then turn on VerboseLogging and have a look at it.
' Make sure to turn off VerboseLogging for production because it could slow down your application.)
Debug.Print zip.LastErrorText
