Re: Calling a batch file from web application [modified] - ASP.NET Discussion Boards

Hey Yusuf. Thanks for the reply. Trust me, I know all about jQuery. I'm the guy who got it adopted at work. Unfortunately, the code I'm talking about is generated dynamically by ASP code in a 3rd party application where I work. We've actually done some research today, and it's related to how the Citrix servers were set up, though we don't know the full details yet. I'll post the results here when I find out.

Hello.

I am trying to make my own (freeware) Rapidshare downloader in C# and I need a way to do the button press simulation (for the "Free User" button on the rapidshare page). Below is the HTML code for the 2 available buttons (free & premium). Right now, I am using a WebClient to get the HTML page and I 've read on the net that I must make an http Request for the link placed in the value of action. However this is not enough (I return to the same page). I guess I must use the HttpWebRequest, the action="..." and the id="ff" to make it work. Can anyone tell me how exactly (because I have no idea yet... Cry | :((

) ?
(I mean... where do I put the id)
I 've found this: How to use HttpWebRequest and HttpWebResponse in .NET[^] but should I put the id in the webrequest.Headers like that (?):

webrequest.Headers.Add("id", "ff"); ???

On second review, it seems that Rapidshare is well protected so that download-manager-makers have a hard time... Perhaps I should post a question here : http://www.hackforums.net[^] Sigh | :sigh:

You are trying to second guess rapidshare ( for that matter any other site ). What happens if they change they page or controls? you code will be easily broken.

Yusuf

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Yes. That is a problem. However, if I learn how to do it once, then I could do it easier and faster the next time(s). And in the process of trying, I will learn new things.

As a poet would say (I don't like poetry by the way...) it's more about the journey, not the destination. Wink | ;)

Greetings...

I'm currently working with IIS 5.1, developing a web app using C#, and testing on win xp pro. One of the functions of the web app is to map a drive letter to a network resource. The way I'm going about this is calling a batch file from the application:

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents = false;
proc.StartInfo.FileName = @"C:\tmp\testBat.bat";
proc.Start();

The batch file contains the following:

copy "C:\tmp\src\test.txt" "C:\tmp\dst\testcopy4.txt"
net use X: <some network="" resource="" path="">

I've setup impersonation in web.config, and am only using Integrated Windows Authentication in the web app. I also mapped the .bat extension to cmd.exe. When I click the button that's associated with calling the batch file, I can see that the file copy works, but nothing happens with the drive mapping command. (this is accomplished by checking whether the directory exists elsewhere in the code).

Any ideas? I hope I posted this to the right place. I'm wondering if it has something to do the particular executable...

Well do you have drive X mapped?

what do get if run net use command

Hi Yusuf,

I didn't realize that the rest of the "net use X:" line got hidden because the editor thought it was html because I placed it between brackets. What I meant to say is:

net use X: <some network resource path>

I didn't review my post closely enough. Apologies!

and update of my troubleshooting, when I look at the task manager on my computer, I see that when the batch file executes, cmd.exe and net.exe run under the ASPNET user name. I'm not sure why this is, since I set up impersonation, perhaps I'm missing something in my configuration?

what do you get if you run your batch file manually on the server.

Yusuf

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

When I run the batch file manually it works. Also I edited my last message, but if you didn't catch it, when the batch runs from the web application, I noted that cmd.exe and net.exe run under the ASPNET user name, and do not seem to terminate. Is this something to do with my configuration? I thought I setup impersonation properly.

alchong wrote:

You need to set the flag to terminate the command window. I don't remember since it has been very long time. run cmd /? and you will figure it out.

alchong wrote:

I don't know. may be asp.net account can not perform network actions. again this is a guess, I have no proof for that.

Yusuf

Hi Yusuf,

/C was the flag.

I guess I'll need to figure out if I can configure impersonation properly to run net.exe & cmd.exe under the web application user credentials instead of the ASPNET account.

Good luck. Let us know your finding. We can all learn from your work. Thanks

The same way as other rest of the pages

Session("yourSessionVariable") = yourSessionValue

This can be handled at the client. You need some javascript code to do it. Google is your friend.

Oh yeah! There are plenty of articles here at CP. Pick your choice and start learning http://www.codeproject.com/KB/session/[^]

Being new is not a problem. We all started somewhere. There is a lot to learn if you willing to read.

Hey all,

In my backend (code), i've got a Bitmap, which I've filled with some pixels.
Now I want to show this image on an aspx page. Does anyone has any idea how to solve this problem.

I've tried <asp:image xmlns:asp="#unknown">, but this needs an url.
I Also tried but this also needs an url.
