you cannot create dll in asp.net instead of you can use Class Libary option on opening new project.

A class library is a DLL.

I want to delete some files from my application. For this I am using System.IO.File.Delete. It gives me error "Access to Path 'C:\EmployeeData\EmployeeJun.htm' is denied."
I did find some articles explaining that account should have privileges to the path or file. I verified that ASPNET account had read and write permission to the folder and to the file (inherited permission from parent). Any idea what is missing here.
In addition, I have web service in application that can delete the same file from within the application. In case account is missing permissions to the file, how File.Delete can delete the same file from web service? Please explain.
Thanks in advance.

Your ASP.NET application cannot access files above the application root. This is by design.

Thank you for reply.
File is not above the application root but under application root.
Like I stated before, I can delete the file from the web service running on the server (personal web server here) and invoked from the application.
File (also created from the application) has Read, Write and Read & Execute permissions already. I just tried giving Modify permission to the file and delete it from aspx page. It worked.
I am confused!!
Kubben, what for is IIS_WPG account?
|
|
|
|
|
IIS_WPG is the iis worker process group. Any user or identity that you are trying to use to be the indentity of the application pool also need to be in the IIS_WPG group. Thinking about it aspnet user would already be in this group. Still the identity of your app pool it probably network service. That group most likely doesn't have rights to delete the file.

If the aspnet user has access you also need to give IIS_WPG access, then it should work.

Hi,
I tried to add user into Active directory using ASP.Net and C# web application. If i tried to add it in "Users" then it successfully added and I can also change that user password.
But if I want to add that user into another "Organizantional Unit" then It add it successfully but create a problem at "SetPassword" method. Web application gives timeout problem. When i tried it in Window application then one popup box is opened. It display me that I am accessing private data.
How can i update private data of Active directory? I used Directory Entry for that. How can i change user's password which is in User defined Organizational unit?
Please Help....

Hope this helps:
public void CreateUserAccountAd()
{
string userID= "CN=userID";
string pass= "password";
// Use this command to add it into other OUs
//string lPath=
// "LDAP://domain/OU=OrganizationalUnit,DC=DomainName,DC=com";
//Use this one to add in default OU
string strpath =
"LDAP://domain/";
DirectoryEntry de = new DirectoryEntry(lPath);
DirectoryEntries child = de.Children;
DirectoryEntry deuser = child.Add(userID,"user");
deuser.Properties["SAMAccountName"].Add(userID);
deuser.CommitChanges();
SetPassword(deuser, pass);
Enable(deuser);
}
private static void SetPassword(DirectoryEntry DE, string password) {
object[] oPassword = new object[] {password};
object ret = DE.Invoke("SetPassword", oPassword );
DE.CommitChanges();
}
public void Enable(DirectoryEntry DE)
{
ActiveDs.IADsUser user1 = (ActiveDs.IADsUser)
DE.NativeObject;
user1.AccountDisabled = false;
DE.CommitChanges();

Hi
I want to get the ip of the machine using a web application.
I used Request.UserHostAddress() and Context.Request.ServerVariables ["REMOTE_ADDR"] but still gives me IP Address: 127.0.0.1
Any ideas?
Could it be a configuration from our network administrator?
|
|
|
|
|
When you are viewing a web page that is hosted on your own computer, you are browsing from localhost to localhost, so the IP address 127.0.0.1 is correct.

That is correct. The reason is that iam using an application hosted on my Laptop 
Try to put the ip instead of localhost u will get the ip right.
thanks for ur response.

Hello Everybody...
I have a web application developed in .net 2.0 which uses SQL Server 2005 as its backend.
No error is thrown when I jus debug from my machine.
But When I host it in IIS it is throwing the error mentioned in subject line.
My connenction string in web.config file just has, server, database attributes along with integrated security is set to true...
And the SQL Server is in Mixed Mode authentication.
Still I face the error.
PS: I could successfully browse the site if i mention some SQL Authenticated User id and password in connection string instead of integrated security...
Is there anyother way without giving the sql userid?
Why do we have to have the sql authenticated user?
-Saran

If you use authenticated security in a .net application then then connection will be made in the context of the process account IUSR_MachineName most probably. It is unlikely that user has access to the sql server and I wouldnt recommend that you add it.
I would suggest using a sql login from the web site rather than integrated authenication.
|
|
|
|
|
If you still want to use integrated security to access sql server you will need to do a few things.
First set up a new app pool in IIS. Point your web app to use this app pool. Next create a network login for the app pool. Set the identity of the app pool as the network user. On the web server add the new user to the IIS_WPG group Make sure the user has the correct read and write rights to the directories that your web app are in. Finally make sure this network user has the correct rights in sql server so the web app will run.
Hope this helps.

We've got an IIS server running with ASP.NET 1 and 2 on it, and are trying to develop an intranet website based on 2. The web pages are being created with a prog that uses version 2 only, and all the settings we can find on the server are also set to use Version 2, but loading a web page always brings up an error, and the ASP version number it contains is always 1.xxxxxx
Any ideas how to configure the server so it uses ASP 2.xxx for the website instead?
|
|
|
|
|
Have you set the website to use v2 in IIS? Go into IIS right click on the web site and go to properties. In the ASP.net tab change the version to 2 and apply.
If the application pool currently has any 1.1 applications running in it you will need to make sure you assign it to a new pool since you cannot mix versions in application pools.
|
|
|
|
|
Thanks for the reply, yes we've set it to version 2.
It could be the application pool thing, I'll have to try and find those settings.
|
|
|
|
|
IF you are running IIS with both .Net 1 and .Net 2 you need to set a different application pool for both. You can share an application pool for all 1 and a seperate one for 2.0 but they cannot have the same pool.

strSqlCmdText = "update tUser1 set Count = "+Convert.ToInt32(txtCount.Text)+" where UserId = '"+txtUserId.Text;
Change to
strSqlCmdText = "update tUser1 set Count = "+Convert.ToInt32(txtCount.Text).ToString+" where UserId = '"+txtUserId.Text;
Also, I should note that you are wide open to SQL injection attacks with that particular implementation.

Can you put a watch on the sql command being executed and paste it in so i can see what command is being executed on the server?
|
|
|
|
|
 Hi,
Try this one..............
strSqlCmdText = "update tUser1 set Count = Convert.ToInt32
(txtCount.Text.trim().ToString()) where UserId = '"+txtUserId.Text;
I think it will run properly.............
