(Visual Basic 6.0) Find a ZIP Entry by Exact Path Using EntryOf

See more Zip Examples

This example demonstrates how to use the EntryOf method to find a ZIP entry whose stored path exactly matches a specified path.

Unlike EntryMatching, which performs wildcard matching, EntryOf performs an exact path lookup.

This method is useful when:

• The exact ZIP path is already known
• Retrieving a specific file or directory entry
• Verifying whether a particular entry exists in the ZIP archive

Suppose the ZIP archive contains:

docs/
docs/readme.txt
docs/manual.pdf
images/logo.png
data/config/settings.json

ZIP archives may optionally contain explicit directory entries such as docs/. These directory entries can also be retrieved using EntryOf.

The example:

• Finds an exact file entry
• Finds an exact directory entry
• Demonstrates the difference between file and directory entries

Note: This example requires Chilkat v11.0.0 or greater.

    Debug.Print "  FileName = " & entry.FileName

' Find a directory entry.

' ZIP archives may optionally contain explicit directory entries.
' In this example, "docs/" is a separate directory entry.

success = zip.EntryOf("docs/",entry)

If (success = 1) Then
    Debug.Print "Found directory entry:"
    Debug.Print "  FileName = " & entry.FileName
    Debug.Print "  IsDirectory = " & entry.IsDirectory
    Debug.Print ""
End If

success = zip.EntryOf("images/missing.png",entry)

If (success = 0) Then
    Debug.Print "The entry images/missing.png was not found."
End If
