Returning Value From Process (batch File) To Webpage?
Jan 13, 2011
I'm using the System.Diagnostics.Process class to run a batch file. I need to be able to take an output from the batch file and then display it on the web-page, basically to know if it succeeded or not, since the batch runs an .exe that doesn't always succeed.
the values returned by the .exe and have the batch run a script depending on the value returned. The script could be a VBscript that sends info to the webpage, but even then I'm not sure how to accomplish this.
If I watch the processes tab in Task Manager on the web server I see "cmd.exe" under the context of 'administrator' but it just hangs. For test purposes c:SendV80s.bat: copy c: oot.ini c:zzz.txt
If I logon onto the webserver's console and execute SendV80s.bat it works and exits without issue. But when I execute the same batch file via the Submit button it gets stuck executing in Task Manager/Process. I believe this has something to do with the fact that cmd is not running in a full environment/desktop context. I just noticed this on the actual console of the webserver (not in my RDP console but console 0 instead)
A pop-up box stating: CMD.exe Application error The application failed to initialize properly (0xc0000142). Click OK to terminate the application. And when I click on the OK button my ASPX page's WaitForExit is satisfied and the continues processing normally.
I need to fetch first 75 data or lines and insert in the sql table. Again next 75 data or lines and insert in the sql table. Again next 75 data or lines and insert in the sql table until it finish all.How i can do it in ASP.NET with C#
What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.
Approaches I can think of (and their disadvantages): 1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?
2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.
3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.
I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:
FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read); BinaryReader reader = new BinaryReader(fsr); byte[] bytes = new byte[fsr.Length]; reader.Read(bytes, 0, bytes.Length); FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write); BinaryWriter writer = new BinaryWriter(fsw); writer.Write(bytes, 0, bytes.Length); // clean up writer.Flush(); writer.Close(); writer = null; fsw.Close(); fsw.Dispose(); fsw = null; reader.Close(); reader = null; fsr.Close(); fsr.Dispose(); fsr = null; Later after sending the email I: mailMessage.Dispose(); mailMessage = null; foreach (string fileName in attachments) { if (File.Exists(fileName)) File.Delete(fileName); }
The error occurs at: the File.Delete(fileName);
how I can delete or reopen these files after sending the email?
Apologies if my question is too broad but I eed pointers on how to tackle the following problem. Currently, I run a batch file that launches a series of automation tests on QTP (a test automation tool). The batch file contains a vbs script path and it takes three parameters. Each time smeone needs to run the automation, I have to do this manually.What I'd like to be able to do is to allow other members of the team to access this functionality via an intranet web page. They would be able to login, choose the tests to run and then run them. My only other requirement is that the solution be based on .net and C# if possible. My current server is 2003 SP2.What is the best way to achiveve what I want? What is the recommended version of IIS and .NET framework to use? How do I configure IIS to be able to run the vbs script? I'm looking for a step-by-step approach if possible. I don't care if I have to convert the batch file into an executable or run the script directly, just as long as it is launched.
I am trying to download a file from the server but i am getting this error:
The process cannot access xxxx the file because it is being used by another process
This is my CODE: string fileName="DownLoadFiles"; string filePath = hid_filepath.Value; FileInfo file = new FileInfo(filePath); System.Net.WebClient wc = new System.Net.WebClient(); wc.DownloadFile(new Uri(fileName, filePath);
Foe ur Information:the file is not opened or not used.
I have a problem which is a recent development. We used to be able to run a batch file from IIS, but now we can't. I have tried several different approaches to this issue, none of them have worked. I tried to run the batch file under cmd using CreateProcess, CreateProcessWithLoginW, CreateProcessAs User, none of which worked. I now know that CreateProcesswithLogonW won't work on Windows 2003 Server. This is a C++ webservice by the way, running on Windows 2003 server using IIS 5.1. I have also tried running the batch file from a vbs script and calling the script in C++ using system("Scriptname") and that does not work either. I have run out of options, or at least the options that I know about.
I learned that "EXEs in System32, which like CMD.EXE have "special" ACLs that prevent them from being launched remotely from IIS. CMD.EXE has further security checks inside of it to prevent being used to launch batch scripts launched remotely from IIS." So I have abondoned even attempting to run CreateProcess of anykind where I invoke "cmd.exe" to run a batch file. Which was why I tried the vbscript. I know this is a security issue. It has to do with either the NETWORK SERVICE account or the ASPNET account not having permission to do this. I have QA breathing down my neck at this point and I really need to figure out what to do. If it is a security setting that can be set without compromising security on the server then great (although I bet that isn't the case).
My code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?
here's the code:
protected void Page_Load(object sender, EventArgs e) {if (!IsPostBack) // if this is the first time page loads, set k to 1 { lognewuser(); }}
I am having the text file which is used to track all the ip address which is available in the network and replace the content from"Reply from 172.29.116.3: bytes=32 time=1ms TTL=255" to 172.29.116.3.
For this task i am having 2 functions 1.runCMD() Function is used to create a file which ping all the ip address between 3 to 254 ("Reply from 172.29.116.3: bytes=32 time=1ms TTL=255").
2.Another function textFileReplace() which is used to replace the text from "Reply from 172.29.116.3: bytes=32 time=1ms TTL=255" to 172.29.116.3.
This process will continue every 30 minutes..
But i am having the error while accessing the function textFileReplace() as The process cannot access the file 'C:inetpub' because it is being used by another process.
I am creating an intranet application which runs a batch file and create an xml file as result. Which i am using for further processing. My problem is when i am running my application from local machine batch file is running fine and creating xml,but when i am running it through iis nohting is happening,
it meance process.start coudn't start command Prompt.
I am using following code. I have given all permission to iis.
Dim ProcessInfo As Diagnostics.ProcessStartInfo ProcessInfo = New Diagnostics.ProcessStartInfo("cmd.exe", "/C " + Server.MapPath("~myScript.bat")) Dim Process As New Diagnostics.Process ProcessInfo.CreateNoWindow = False ProcessInfo.UseShellExecute = False
I have a batch file on another server on a different domain or network that I need to run from an ASP page. I found a simple enough script that opens a CMD prompt, goes to the location of the batch and runs it. If everything is on the same machine, it runs fine.
The issue I've run into now is that the batch file is on a file server and the ASP page is on a IIS server. The File server is on a internal network (separate domain) and the IIS server is on an external network (or different domain), both servers are hosted here.
When I try it and look at the event logs I can see a failure audit and its trying to login with the machine name.
I have to open a batch file automatically in sql. So i have used the below command.EXECUTE master.dbo.xp_cmdshell 'D:Databasesatch123.bat'Its worked for few times. After that its not working.One time i have stopped before the process is complete.May be this is the issue.Now its returns null value.
i have made one web site which is generating screensaver(MSI) dynamically.So to generate the MSI file i have to build a WIX project.So i executed using batch file which will use MSBuild.exe and cmd prompt. so its gave me an error "Access is Denied". i have also tried by making a windiws service but still the same error occurs.
When I delete all files from the directory path. then it will give me this error The process cannot access the file because it is being used by another process. How to solve this?
I am getting binary data from a SQL Server database field and am creating a document locally in a directory my application has permissions. However I am still getting the error specified in the title. I have tried numerous suggestions posted on the web including those suggested in previous posts on Stackoverflow. I have also used ProcessExplorer > Find Handle to locate the lock and it returns nothing as if the file is not locked.
I am using the code below to save the file to the file system and I then try to copy this file to a new location later in the application process within another method. It is this copy method that takes the path of the newly created file that throws the exception.
The file itself is created with its content and i can open it through Windows Explorer without any problems.
Am I missing something completely obvious? Am I creating the file correctly from the database?
// Get file from DB FileStream fs = new FileStream( "C:myTempDirectorymyFile.doc", FileMode.OpenOrCreate, FileAccess.Write); BinaryWriter br = new BinaryWriter(fs); br.Write("BinaryDataFromDB"); fs.Flush(); fs.Close(); fs.Dispose(); // Copy file File.Copy(sourceFileName, destinationFilename, true);
I am using a AsyncUpload(telerik), i am in a point where i am supposed to save the File to a certain Folder. First I check if the directory exist
Code: Dim baseDire As String = Server.MapPath("~/MyFILES/") If IO.Directory.Exists(baseDire & Request("Req_ID").ToString()) = False Then IO.Directory.CreateDirectory(baseDire & Request("Req_ID").ToString()) End If
Because i am doing multiple Upload , i will have to loop through the items of the Upload control and save to a folder.
Code: For Each file As UploadedFile In UploadPropDoc.UploadedFiles Dim bytes(file.ContentLength - 1) As Byte file.InputStream.Read(bytes, 0, file.ContentLength) 'Save the File to the disk file.SaveAs(baseDire + file.GetName()) Next
Now when ever i debug this , when it comes to this line
Code: file.SaveAs(baseDire + file.GetName())
I get an Error
The process cannot access the file because it is being used by another process.
I have removed the Readonly in the Folder that it supposed to write to and gave everyone permission , but still the error persist.
Is there anyways to launch Cassini web server from a command line? The exe appears to be in this path, C:Program Files (x86)Common Filesmicrosoft sharedDevServer10.0
I have a asp.net web site, I would like a page on that site to be able to invoke a Windows Scheduled task or a batch file on a server different to the IIS server?
