I’m trying to zip a file on Windows using an OLEObject and am not getting very far because of a strange error.
First, I am working off of this post:
https://stackoverflow.com/questions/19302634/creating-a-zip-then-copying-folders-to-it
I tried this code which is purely for testing. I’ve marked the error:
dim sourceFolder as FolderItem = SpecialFolder.Desktop.Child( "xxtest" )
if not sourceFolder.Directory then
AddToResult "Source is not a directory!"
return
end if
dim zipFile as FolderItem = SpecialFolder.Desktop.Child( "xxtest2.docx" )
static nulls as string
if nulls = "" then
dim mb as new MemoryBlock( 18 )
nulls = mb
end if
static pkHeader as string = "PK" + ChrB( 5 ) + ChrB( 6 ) + nulls
dim objFSO as new OLEObject( "Scripting.FileSystemObject" )
objFSO.OpenTextFile( zipFile.NativePath, 2, true ).Write( pkHeader )
dim bsZip as BinaryStream = BinaryStream.Open( zipFile, true )
bsZip.Position = 0
bsZip.Write pkHeader
bsZip.Close
bsZip = nil
zipFile = new FolderItem( zipFile.NativePath, FolderItem.PathTypeNative )
dim sourceParams( 1 ) as variant
sourceParams( 1 ) = sourceFolder.NativePath
dim zipParams( 1 ) as variant
zipParams( 1 ) = zipFile.NativePath
dim copyHereOpts as integer = _
kCopyHereOptionNoProgressDialog + _
kCopyHereOptionYesToAll + _
kCopyHereOptionNoDirectoryConfirmation + _
kCopyHereOptionNoDialogOnError
dim shellApp as new OLEObject( "Shell.Application" )
dim source as OLEObject = shellApp.Invoke( "NameSpace", sourceParams )
// Next line goes BOOM!
dim zip as OLEObject = shellApp.Invoke( "NameSpace", zipParams )
// OLEException: Exception, (failed on "NameSpace")
zip.CopyHere( source.Items, copyHereOpts )
Exception err as RuntimeException
System.DebugLog Introspection.GetType( err ).Name + ": " + err.MessageSince the file is created, and has content, what am I doing wrong?
(Yes, I know I am writing to the file twice, but I wanted to show the different methods and combinations I’ve tried.)
