Why OpenDocumentEx method returns null while opening some files?

Mon, 26 Jan 2026 16:26:21 GMT

Hi!

I'm working with QlikView docs via OCX API.

For opening files, I'm using this code:

var doc = axQlikOCX1.OpenDocumentEx(url, 1, false, Username, Password);

For some docs it returns null, without throwing any Exceptions etc.

Could you explain, how I can get reason of this behavior (message etc.) ?

Thank you in advance!
