.NET Forum / ASP.NET / General / August 2007Calling a windows application from inside the browser
Hello, Can I call, run, a windows application from my web application when the user fires a certain event ? Thank You. > Can I call, run, a windows application from my web application when the > user fires a certain event ? Not natively - imagine if you could run format c: from behind a button... :-) OK, that's a bit of an extreme example, but you get the idea... :-) You could use something like WSH (or a bespoke ActiveX control) for this, but you would also reduce your browser security settings... Obviously this would limit you to IE, so no use at all for a public website...  SignatureMark Rae ASP.NET MVP http://www.markrae.net Thank you for your reply but I have no idea what WSH is. >> Can I call, run, a windows application from my web application when the >> user fires a certain event ?

However, I'd strongly advise you not to even try to do this - one of the main security features of all modern Internet browsers is geared specifically to preventing this sort of activity... SignatureMark Rae ASP.NET MVP http://www.markrae.net It is an intranet application. Browser security issues can be arranged with the customer. So, how can I accomplish the required task with Active X, WSH or any other way. >> Thank you for your reply but I have no idea what WSH is. > [quoted text clipped - 3 lines] > main security features of all modern Internet browsers is geared > specifically to preventing this sort of activity... > It is an intranet application.

Use System.Diagnostics.Process.Start() The executable will run as the ASP.NET account, so the ASP.NET account will need whichever permissions the process needs. Juan T.

I interpreted the OP as wanting to run a Windows app client-side... SignatureMark Rae ASP.NET MVP http://www.markrae.net Yes, I want to run a Windows app on client-side... I have created a test web site consists of one page and here is its code : protected void Page_Load(object sender, EventArgs e) { System.Diagnostics.Process p = new System.Diagnostics.Process(); p = System.Diagnostics.Process.Start("IExplore.exe"); } It is not working and no exception appears ..!! >> Use System.Diagnostics.Process.Start() >> >> The executable will run as the ASP.NET account, >> so the ASP.NET account will need whichever permissions the process needs. > > I interpreted the OP as wanting to run a Windows app client-side... > Yes, I want to run a Windows app on client-side... That's what I thought, though you didn't specify that in your original post... > It is not working and no exception appears ..!! It won't work, because it is trying to run Internet Explorer on your webserver... Can you please explain *precisely* what you're trying to do here... SignatureMark Rae ASP.NET MVP http://www.markrae.net Here is what I'm trying to do. Calling this windows application, Archiving.exe, on the client side .... protected void Page_Load(object sender, EventArgs e) { System.Diagnostics.Process p = new System.Diagnostics.Process(); p = System.Diagnostics.Process.Start(@"C:\Program Files\The Pen IT\Archiving System\Archiving.exe"); } >> Yes, I want to run a Windows app on client-side... > [quoted text clipped - 7 lines] > > Can you please explain *precisely* what you're trying to do here... > Here is what I'm trying to do. Calling this windows application, > Archiving.exe, on the client side .... > System.Diagnostics.Process p = new System.Diagnostics.Process(); I already told you that won't work - that is server-side code, not client-side code. I've already provided you with a link showing you how to do this client-side - here it is again: http://www.faqts.com/knowledge_base/view.phtml/aid/31646/fid/124 SignatureMark Rae ASP.NET MVP http://www.markrae.net re: !> I interpreted the OP as wanting to run a Windows app client-side... I wish him good luck with that chore if that what he wants. An ActiveX object would be the first thing to try but I, like you, discourage their use given the security issues. Users have to approve the installation of any ActiveX object ...and that is enough to cause problems. The whole idea of the .Net Framework is *not* to do client-side processing, except for UI actions and notifications which use Javascript, for which Ajax is the ideal vehicle, although it will *not* run executables client-side either.
