Re: How can I pass a parameter form one document to another in a Zero-FootPrint interfase?
If you are using QVP, then credentials will pass provided you use QlikView Server and Plugin version 11.20 SR3 release 12018. Otherwise, you will not be able to do that.
Also, this will need to have your QlikView server set in your Intranet Zone in your Internet Explorer settings or going to the Custom Level of Internet Explorer Options, make sure that you have set "Automatic logon using current username and password".
Apart from user and password, you can use an action in a button object or text object type External, Open QlikView Document and set "Transfer State".
