Question

How do I open a link in the same browser tab? I tried this code:

ShellExecute(Handle, 'open', 'http://site.com', '_self', nil, SW_SHOWNORMAL);

But it continues to open the link in a new table.

Thanks.

I’ve written on this topic before:

ShellExecute has absolutely no notion of “tab.” In fact, it doesn’t
even have a notion of “default browser.” All it does is find whatever
program is configured for file names that start with “http://” and
execute the configured command line.

What the browser does with the new command line is its own choice.
The API function has no control. Sometimes, the browser allows the
user to configure it.

Opening a new tab or window is the safest thing to do. Neither you
nor the browser knows whether the user is still using the previous
tab or window.
