I am using asp.net 2005, and my deployement server is Windows Server 2003.
I am invoking a .bat (which executes some cmd) file from my asp.net page.
But the cmd prompt not getting invoked . the application is waiting for long time in Process.Start() and after some time i am getting asp.net time out error.
Note : a. Same application is working in another production server with windows 2003
b. i have checked with giving impersonation = true - It doesnt worked
c. I have checked with gsetting identity as 'Local System' , 'Local Server'in th eApplication pool of the IIS.
I have a web app which displays some data in a GridView. This GridView is populated with a method called BindGrid. The user selectes one or more rows from the grid, then clicks the Process button. What needs to happen is that the selected rows are assembled into a CSV file which is downloaded to the browser, then the database is updated to reflect which rows were selected, and the grid is refreshed so the previously selected rows are no longer displayed. This all sort of works, except...
My code is below, which is very similar to lots of snippets found in this forum.
The problem is that if I uncomment Response.End(), or replace it with ApplicationInstance.CompleteRequest, it all works great except none of the code after Response.End() executes, and so the log entry is not made and the grid is not refreshed.
If I comment Response.End(), as in the snippet below, the code following does run, including the log entry and the call to BindGrid. (I know that because log entries inside BindGrid are made.) However, the page does not refresh. If I press F5 to refresh the page, it redraws correctly refreshed.
So the question is, how do I refresh the page after downloading the file?
I have tried calling both Response.Redirect and Server.Transfer after BindGrid
For what it is worth, I am using IE7.

View 1 RepliesI am working on Windows 2008 Server (64-bit). I want to execute my web service as a pure (native) 64 bit service. All the assemblies referred by the web service are currently built as 'AnyCPU'.
When I publish the web service to IIS, and configure it to run under a 64-bit application pool (by setting 'Enable 32-Bit applications' = false), attempt to access the web service gives the error 'Application is not a valid Win32 application' because of a BadImageFormatException. This appears to indicate that somewhere an attempt is being made to load a 32 bit assembly. But the error does not provide any information about which assembly was found with an incorrect format. I have checked all the assemblies in the bin folder using corflags and they are bit agnostic.
I tried using the fusion log and identified a bind failure with VJSharpCodeProvider (though my service is coded only in C#). The runtime is not able to find the VJSharpCodeProvider because it is present in the GAC as an x86 assembly.
Is VJSharpCodeProvider the cause of the problem? I guess this is not the case because of the type of exception (BadImageFormatException). If I am correct, then how do I identify the assembly that is causing this exception?
If I change the property 'Enable 32-Bit applications' to true for the application pool, the service works fine, but I need native 64-bit execution.
I'm developing a Web tool in ASP.NET 2.0 with AJAX . Its working fine in Local Server. When i deployed it in Development Server and executing the Application , I got an error
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(),
response filters, HttpModules, or server trace is enabled.
Details: Error parsing near ' I didn't use any Response.Write in the Application. How can i solve this issue ? Any body knows the solution for this ?
I have developed an ASP.NET MVC Web Application to execute PowerShell scripts.I am using the VS web server and can execute scripts fine. However, a requirement is that users are able to execute scripts against AD to perform actions that their own user accounts are not allowed to do.Therefore I am using impersonation to switch the identity before creating the PowerShell runspace:
Runspace runspace = RunspaceFactory.CreateRunspace(config);
var currentuser = WindowsIdentity.GetCurrent().Name;
if (runspace.RunspaceStateInfo.State == RunspaceState.BeforeOpen) {
runspace.Open();
}
I have tested using a domain admin account and I get the following exception when calling runspace.Open():
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Requested registry access is not allowed.
The web application is running in full trust and I have explicitly added the account I am using for impersonation to the local administrators group of the machine (even though the domain admins group was already there).I'm using advapi32.dll LogonUser call to perform the impersonation in a similar way to this post (http://blogs.msdn.com/webdav_101/archive/2008/09/25/howto-calling-exchange-powershell-from-an-impersonated-thead.aspx)
Actually I don't know whether my question is related to this thread.
I want to create a web application using ASP.NET MVC 2.
For simplicity, let my scenario be as follows:
A visitor is allowed to submit a text file and get a pdf output from the server.
There is an Adobe-Acrobat-like application, that can convert text to pdf, running on my server.
My question is how to execute the converter such that each visitor submitting files cannot interfere with others?
Should I make an instance of the converter for each visitor?

View 3 RepliesI am looking through a sql stored procedure which I might need to update in the near future. Basically the stored procedure is about 20 lines long. The stored procedure first builds a query
and stores it in a variable named "@Sql". And then for the last two lines of the stored procedure it appears that the big sql statement stored in "@Sql" is executed by using the "EXEC" command. See below. What is confusing though is that the query appears to be exectuted twice? Why was the query written in this way. Don't both lines do the same thing? Why is it being done twice? Could this possibly be a mistake on the
part of the person who wrote the query. Below are the two lines I am talking about?
EXEC sp_executesql @sql
EXEC (@sql)
I am just planning to create a blog type of web application. But i am not understanding how do i rewrite url's? say suppose site is xyz.com then when some user registers with name of T then he can visit blog at T.xyz.com? As you can see the url's will keep on changing dynamically.
I don't want to keep creating sub domains for each new user joined on the site. How can i achieve this?
I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously.
In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says
"object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread.
My question is, how can I asynchronously execute the Server.Execute method?
I'm reading an ASP.NET book that says you can't use Profile if you select Web Application when you start a project. It only run under Web Site.
