Create Password Protected Zip containing a Single File.
Create a password-protected .zip containing a single file. (This uses the older Zip 2.0 encryption scheme, which is weaker and not as secure as AES encryption, which Chilkat Zip also supports.) Dim zip As New ChilkatZip2 Dim success As Long ' Any string unlocks the component for the 1st 30-days. success = zip.UnlockComponent("Anything for 30-day trial") If (success <> 1) Then MsgBox zip.LastErrorText Exit Sub End If success = zip.NewZip("test.zip") If (success <> 1) Then MsgBox zip.LastErrorText Exit Sub End If zip.SetPassword "secret" zip.PasswordProtect = 1 Dim saveExtraPath As Long saveExtraPath = 0 success = zip.AppendOneFileOrDir("c:/temp/hamlet.xml",saveExtraPath) success = zip.WriteZipAndClose() If (success <> 1) Then MsgBox zip.LastErrorText Exit Sub End If MsgBox "Zip Created!" |
