Re: WebBrowser.Document.ExecCommand / SaveAs / vista, ignores parameters

This is a secuity limit
Since you are hosting the control, you can parse the page for the target URL
and make another web request to download the file.

I'm using a webbrowser control on vista to programmatically save files
from the web.

I'm trying to use the WebBrowser.Document.ExecCommand function with
the SaveAs command, as documented in

http://msdn2.microsoft.com/en-us/lib...8VS.85%29.aspx

[I replaced ( and ) in the URL by %28 and %29 because my news agent
doesn't seem to support links with those characters]

This results in something like

: br2.Document.ExecCommand("SaveAs", False, DownloadPath)

This works, but the last two arguments are ignored.

The "save as" dialog always pops up even though I tell it not to, and
the initial path is in My Documents.

I replaced \ by \\ in the path as indicated in the docs, but whether I
do or don't doesn't make any difference.

Could this be a (security or other) setting in IE, or does IE7/Vista
simply not work as documented in MSDN?

Or perhaps you can give a hint to help solve my original problem: I
had to resort to a WebBrowser because the site where I'm downloading
from is secured, and when I use a HTTPWebRequest I get some html code
asking me to log on instead of the image, even when I'm already logged
on to the site through a webbrowser control in the same app.

Using the logon functionality in the HTTPWebRequest doesn't work
because the site uses a PHP form for logging on.

Using a second WebBrowser instead of a HTTPWebRequest solved that
problem, but now I'm stuck on those save dialogs.

A lot of work for an application that will be used only once, but the
alternative is clicking "save target as" and confirming the download
location in a standard web browser hundreds of times.
