I have implemented this in my website as per my requirement. [URL] It is working fine in local. But i moved that code to dev server today... it is showing all the drives of dev server. (But my fuctionality is it should show all the drives of local computer who is accessing this ste).
View 1 RepliesI have M:PDF-ImagesList-PDF drive on the Server with thousands of images stored.
On the M drive has folder:
M:PDF-ImagesList-PDF45404539532.pdf
4539533.pdf
4539534.pdf
4539537.pdf ...
How to access to the folder drive by using VB.NET or C# in the code-behind (securely: with username and password) for the users to be able to view images on the popup window?
See the code :
Protected Sub BtnServerDrive_Click(sender As Object, e As EventArgs) Handles BtnServerDrive.Click
Dim PartNumber As String = txtPartNumber.Text.Trim()
'Calculate the folder 4540 like container
Dim NumContainer as string = txtPartNumber.Text.Trim()
NumContainer = (txtPartNumber.Text.Trim / 1000 + 1).toString.Split(".").First
[Code] ....
How to achieve this results to access to the server drive to get images for view by using VB.NET or C# in code-behind. Servermappath, UNC, or else?
I have seen some examples on other sites , but since im not familiar enough with DirectoryInfo and Files from the System.IO namespace, i dont know how to change it to fit my needs. So i found a very simple example that works, but i have some questions.
Here is the code i found:
[Code]....
This works great and lists the files in my root directory.
#1 - What i need to know is how to accomplish the same thing but in a format i can control, this code simply displays the files at the top of my page and pushes everything down. So does anyone know of a good and simple tutorial written in C#?
#2 - I also need to be able to setup the code so that certain files within the directories are not displayed, as in the code behind files and other files to be determined by the business.

I have created an application to upload files to a mapped network drive(say: Z:), but is showing the error:
System.IO.DirectoryNotFoundException: Could not find a part of the path 'Z'.

Short Version: Can anyone say whether it's possible or not to use impersonation in ASP.NET to access mapped drives?
Long Version:
I'm currently using impersonation in ASP.NET to gain access to network files. This is working perfectly for any network file using a UNC path, but it is failing to access any files on mapped drives defined for the user account I'm impersonating.
For example, let's say a file lives on the network at "machinefolderfile.txt", and let's also say that drive S: is mapped to "machinefolder". We need to be able to access both the full UNC path, "machinefolderfile.txt", as well as the shorter, mapped drive path, "S:file.txt".
Obviously the standard ASP.NET process cannot access either.
Using a console application that runs under the local account with the mapped S: drive, calling File.Exists(@"machinefolderfile.txt") returns true, and File.Exists(@"S:file.txt") also returns true.
However, when impersonating in an ASP.NET context with the same local account, only File.Exists(@"machinefolderfile.txt") returns true. File.Exists(@"S:file.txt") returns false.
I'm testing with IIS 7 running on my local Windows 7 Professional box, though this will need to run in both IIS 6 and IIS 7.
Impersonation is handled with a couple of classes in C# which I'll include here:
public static class Impersonation
{
private static WindowsImpersonationContext context;
public static void ImpersonateUser(string username, string password)
{
ImpersonateUser(".", username, password);
}
public static void ImpersonateUser(string domain, string username, string password)
{
StopImpersonating();
IntPtr userToken;
var returnValue = ImpersonationImports.LogonUser(username, domain, password,
ImpersonationImports.LOGON32_LOGON_INTERACTIVE,
ImpersonationImports.LOGON32_PROVIDER_DEFAULT,
out userToken);
context = WindowsIdentity.Impersonate(userToken);
}
public static void StopImpersonating()
{
if (context != null)
{
context.Undo();
context = null;
}
}
}
public static class ImpersonationImports
{
public const int LOGON32_LOGON_INTERACTIVE = 2;
public const int LOGON32_LOGON_NETWORK = 3;
public const int LOGON32_LOGON_BATCH = 4;
public const int LOGON32_LOGON_SERVICE = 5;
public const int LOGON32_LOGON_UNLOCK = 7;
public const int LOGON32_LOGON_NETWORK_CLEARTEXT = 8;
public const int LOGON32_LOGON_NEW_CREDENTIALS = 9;
public const int LOGON32_PROVIDER_DEFAULT = 0;
[DllImport("advapi32.dll", SetLastError = true)]
public static extern int LogonUser(
string lpszUsername,
string lpszDomain,
string lpszPassword,
int dwLogonType,
int dwLogonProvider,
out IntPtr phToken
);
[DllImport("advapi32.dll", SetLastError = true)]
public static extern int ImpersonateLoggedOnUser(
IntPtr hToken
);
[DllImport("advapi32.dll", SetLastError = true)]
public static extern int RevertToSelf();
[DllImport("kernel32.dll", SetLastError = true)]
public static extern int CloseHandle(IntPtr hObject);
}
Then, during Page_Load, we basically do something like this:
Impersonation.ImpersonateUser("DOMAIN", "username", "password");
if (!File.Exists(@"S:file.txt"))
throw new WeCannotContinueException();
I realize using mapped drives isn't a best practice, but for legacy reasons it's desirable for our business. Can anyone say whether it's possible or not to use impersonation in ASP.NET to access mapped drives?
I want to show xml which is load from sql server with the following code but I dont know for showing that in web which control is suitable?the code is as follow:
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["WebApplication1.Properties.Settings.mycon"].ConnectionString))
{
con.Open();
SqlCommand cmd = new SqlCommand("select * from ajaxmovie FOR XML AUTO ", con);
XmlReader xr = cmd.ExecuteXmlReader();
xr.Read();
string data;
do{
data=xr.ReadOuterXml();
}
while(!string.IsNullOrEmpty(data));
I am trying to set up a POST from one aspx file to another progromatically. Inside the POST is a String of XML data which i have properly added to Server.HtmlEncode(). For some reason, when I grab it in my logs on the other page, it is showing with 3 question marks. I at first thought it was logging text i left somewhere, but have narrowed it down to a Encoding error of some sort because when i change the encoding it changes the character, and when I just put some text in there, i see it on the other side fine. i have tried UTF 8,UTF32,Unicode,ASCII... Can't seem to find the right combination. Can't find the UTF-16
when I use the Encoding object
Below is my Code:
[Code]....My Sending Debug log has the Extension xml coming out in HTML format correctly before POST. Below is just a piece of it[Code]....
And then on the other side log I get the below
Extensions =??

I have a company that catagorizes people under Membership 1 and Membership 2.
It is possible for a person to have 0, 1, or 2 of these memberships.
I have a select statement, that I'm building in a view, that shows if a person has no membership, Membership 1, or Membership 2 along with their name, user id, and company. However, if the person has both Membership 1 and Membership 2 it is showing up as two records.
Can I have it show all of this information in one record per user?

View 1 RepliesALL the server controls are not showing in Visual Studio ASP.net project. It used to be intermittent, I would restart devenv and they would show again(even if the layout was terrible) Anyhow now it's not showing at all. The only change I made to the project was to switch Membership providers to MySql. Even pages that have no reference to Membership don't display.Anything(page wise) that has a server control fails (displayes the message "hresult e_fail when creating com component") even if it's just a label with no programming logic.

I created and populated a database inside Visual Studio 2008 instead of using Management Studio.I need to run the script to create the schema for users and roles.The database does not show up in ASP.NET SQL Server Setup Wizard or in Management StudioThe only databases that do show up are master, model, msdb, and tempdb
Is there anything I can do to fix this or would it be easier for me to just create a new database starting in Management Studio and then connect to it from within Visual Studio?
I had problems showing my .aspx files on my server after "copy website"-ftp, as the server had ASP.NET version 2.0. However, html-files worked like a charm. I got my server-dude to install ASP.NET 4.0 on server, and I can now publish an empty aspx-file only containing text without error. BUT, if I add a standard login-form from ASP.Net and copy the website, it says "Server Error in '/' Application", "Configuration Error" blablabla and "Line 8: roleManager enabled = "true"/>" is highlighted in red..And also some IIS-errors. What is IIS? I thought IIS was for people who ran websites from their computers? Is this an IIS-error? What can I do to fix this?
