    View password protected zip file

    Hi all,

    I'm using VB viewzip sample code. Normal zip file is OK to be listed. However the error occured when viewing password protected file.

    Error code is "No password set" at line "objEntry = strmZipInputStream.GetNextEntry()". 

    Most archiver such as Winzip can view password protected zip file without password.

    Please teach me bypass this error.

    Hi,

    The library should allow this.  What version are you using?

    Cheers, -jr-

    This sample attempts to show the file contents.  You can view names and so on (if they arent encrypted which is also possible) without a password but not any encrypted data.
