How to check qvd is available in qvw files using OCX c#

[#1]

Hi is there any way to find qvd is availabe in qvw files using qlikview ocx??

Do not understand your question.Do you want to determine if a qvd exists from the load script, or do you want to do that from a bat file or C# executable?

i want to check it from c# exe... when i load qvw file i need to know weather data or qvd  is available. just need to find its is dashboard or template.

Why do you need a c# exe to determine whether a qvd exists when reloading your dashboard? Just use the built-in functions:

     Let vQVDExists = (Alt(QvdNoOfRecords('E:\QVDFiles\myQVDFile.qvd'), 0) > 0);

     If vQVDExists Then

          ... do stuff

     Else

          ... do other stuff

     End If
