From: JB on 30 Aug 2010 21:44 Hello Cubaman From a web application you can call a Windows application. I have seen it done. When the Windows application gets executed a dialogue box appears that says File Download - Security Warning. Then the name of the file which is a batch file and its location. You have the option of Run, Save and Cancel. If you click Run, you will see the application get executed in batch mode. I am just not sure how the batch program is being called from an ASP.NET menu. Does that give you any ideas on how that is setup to run like that, if so how is it done? fyi, the Windows application was setup using ClickOnce.

Hello JB: Well, if the user downloads and run any file from internet, it's not you website the one running the app, but the user. Just place a link to a bat file on your web menu and instruct your users to run it. The problem I see here is getting the right path to your clickonce app, as it's installed in Local App folder with a very long and obscure path that will be different for each user. If all your applications will be deployed via click once, a possible solution is creating a page with links to your clickonce applications, deployed in on-line execution mode only. Let me know if you need further assistance. Best regards.
From: JB on 31 Aug 2010 21:50 Hello Cubaman I was thinking so far ahead I should have phrased the question differently because I knew that a Windows application could be executed from a dos batch file program because I saw it and since I used to write dos file batch programs I knew how to create a batch file program already. So I went ahead and created the batch program and it does work. However: When using ClickOnce it creates/deploys the Windows application (.exe) from the local hard drive onto the server in a folder named Inetpub\wwwroot. The file ClickOnce creates to install the Windows application from there onto the client from there is named Publish.htm . Publish.htm then puts the application in the users Start menu. That means there is no Windows application.exe file created by ClickOnce for the batch file to execute on the server. So the batch file has to execute the actual Windows application (.exe) from my ocal hard drive that it was created on which is what the user sees and uses. That is how I created the batch file to work and it does work. So the question actually is will the application that the user sees that comes from my local hard drive that I provide access to them work the exact same way as the application that gets deployed to them onto their local hard drive by ClickOnce? The reason that is the question is because the Windows application got executed from a Hyperlink control which states “runat=server, which means things in the Windows application like Messagebox.show may not work because Windows applications run on the client not the server. My thought is that when the batch program runs it is executing the Windows application from my local hard drive and is therefore running from the hard drive and not the server and was only rendered to the user using the Hyperlink. Therefore since it executing off of my local hard drive those features like Messagebox.show should work because they are not running on the server. However I don't know if multiple users are getting their own instance of the application or is only one user able to use the application at a time. Of course the Windows application (.exe) file will eventually be moved to a server because my box isn't on all of time. What do you think? Below is the dos batch file and below that is how the Hyperlink on the web page executes the batch file: ***Batch file:prodTest.bat cd c:\Products\bin\Release c:\ Products\bin\Release \frmProducts.exe" *** the call to the batch file from web page using Hyperlink protected void lnkProducts_Click(object sender, EventArgs e) { ProcessStartInfo prodRun = new ProcessStartInfo("C:\\Products\\prodTest.bat"); Process exProducts = new Process(); prodRun.UseShellExecute = true; prodRun.WorkingDirectory = "C:\\Products\\"; exProducts = Process.Start(prodRun); } Thanks Jeff -- JB "Cubaman" wrote: > On Aug 31, 3:44 am, JB <J...(a)discussions.microsoft.com> wrote: > > Hello Cubaman > > > > From a web application you can call a Windows application.

Publish.htm just point to a file with application extension (*.application) This file contains information needed to install and/ or run your app. If you publish it as a local app, then it will be deployed to the user's local folder, something like "C:\Documents and Settings\<username>\Local Settings\Apps\2.0\<x>\<y> \<z>". If application is available only on-line, it's copied to a local temp folder and executed. You can not run a windows program embedded on a web page, not even using "runat="server".

From: Mark Northup on 6 Oct 2010 09:33 Hi Cuba man, I can positively tell you that your lnkProducts_Click method is going to run on the Web Server. There is no way for this to execute on the client. Remember, the client is a browser! It can execute Java, ActiveX, and JavaScript, and maybe a few other things. The only reason your program has been somewhat successful is because your client and server are on the same machine. Click-Once is a method of deploying an application from a Web Server to a client. NOTE: Client machines do not have a Inetpub\wwwroot folder unless they are running their own IIS web server. I hope this helps, Mark "Cubaman" <oscar.acostamontesde(a)googlemail.com> wrote in message news:2b8f0bc6-16e5-4917-aa46-385c2ec9e1c2(a)t20g2000yqa.googlegroups.com...
