I want the enable a user to download/display a pdf-file which is created
by a module of EWBServer.

To open a new page I use this code:

window.open(MyURL,'_blank');

The problem is, that depending on the browser, a popup window is opened
or blocked.

When I use a TLink, Chrome e.g. opens the URL in a new tab, what is
exactly what I want.
So it would be a simple solution for me to create the pdf, assign the
URL to a TLink and execute the link. But how can I do that in code?

P.S. I can't use an additional Form with a Page-control, because I don't
know whether the user's browser has a PDF plugin installed. If not, a
TLink would just download the file.

Thanks Uli

Not 100% but I sure hope this cannot be done at all - if you have
blocking enabled then user has to disable it. Adding your url to trusted
sites list might help also.

What you are asking for is javascript to be able to bypass popup window
blocking.

This is the exact reason this was invented and browsers go to great
lengths to prevent malicious scripts from opening numerous windows and
allowing only true mouseclick from doing so

Presumably the key is that you want to open it automatically, and not
in response to a user action (the TLink would do it), and without
losing the current page (you can tell it to go to another URL easily).

 Window.Location.href := MyURL;

I suspect you can't do what you want without those popup issues - but
the user can tell the browser that popups are allowed.

You are right - I'll have to find another solution. Maybe a confirmation
dialog with a TLink, that the user has to click on.

Thanks - please see my answer to Raul.
