After a users log on I want to then point them to a page which is dictated by their presence in a project table.
I have created the table with the user names and userIds in
I have written some of the code but need advice on the bit which compares agaist the table.
Label.Text = Membership.GetUser().ProviderUserKey.ToString (this works fine)
Then I want to say something like:

Access :: Vbscript Page Won't Open When Linked To Database?
Mar 1, 2010In school we have been making a website where we need to use .adp vbscript pages. But also Microsoft Access databases.
We've added the connection string etc and bindings - all that works fine but when we go to open the page we get page cannot be found. It loads sometimes but most of the time we get that page not found screen.
We are using IIS.
The teachers and another students one works fine, We have done exactly what they have but we get no luck with bringing up the pages.
We get error 500.100 and Error line 8.

View 6 RepliesConfiguration :: Cannot Get Web Service To Execute In A 64 Bit Application Pool
Aug 17, 2010I 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.

Developed .NET MVC Web Application To Execute PowerShell Scripts?
Apr 16, 2010I 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)
Execute An External Application Such That Each Visitor Gets Isolated?
Jul 21, 2010Actually 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?
Cannot Create A Process In A COM Object (written In .Net4) From An Asp (vbscript) Site
Jan 14, 2011I'm updating an old process that already exists, which works as follows:
The user submits a form which runs the following asp (simplified, names changed):
<%
set rb = Server.CreateObject("RecordBuilder.SomeObject")
rb.Calculate()
rb.StartProcess()
%>
The RecordBuilder.SomeObject was an old VB6 DLL, I don't have VB6, so I converted it to VB.NeT 4.0
The call to Calculate() works as expected, the call to StartProcess() fails.
StartProcess() is the following:
Public Function StartProcess()
Try
strProcess = "Starting process"
Dim proc = New Process()
proc.StartInfo.RedirectStandardOutput = True
proc.StartInfo.UseShellExecute = False
proc.StartInfo.CreateNoWindow = True
proc.StartInfo.FileName = "d:AppRecordProcessor.exe"
Dim procHandle = proc.Start()
strProcess = "Started process"
Catch ex As Exception
Err.Raise(vbObjectError + 9999, "RecordBuilder.SomeObject", strProcess & " failed: " & ex.Message & "<hr />Stack Trace:<br />" & ex.StackTrace)
End Try
End Function
This fails with the call to proc.Start(), however if I copy the test ASP to a .vbs file it will work as expected.
I have changed the permissions on d:AppRecordProcessor.exe to grant execute permission to the group Everyone.

View 3 RepliesSQL Server :: Stored Procedure - EXECUTE And EXECUTE Sp_executesql
Mar 10, 2011I 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)
WCF - How To Execute Server.Execute Asynchronously
Mar 30, 2010I 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?
