Hello all,
I am working on a website which is using Forms Authentication.
For example we have different Roles as Admin and LocalUsers. LocalUser cannot view the Admin Menu Items and cannot access the Admin Pages.
But if the User Copies and Pastes the URL for Admin Page, while he is logged on as a LocalUser, he can see the Admin Page even though he do not have permissions to view that page.
I know that we can check the Roles in the PageLoad before giving access to the Page by User.ISINRole("Admin") and if does not have that role, I can Redirect him to the Login Page.
But is there any centralized way where we can do this. Or do we need to check the Roles in each and Every page.
Thanks In Advance

ASP.NET 1.1
When I'm working on ASP.NET 1.1 projects, I used to create a basepage class that can be inherited from all child classes.
So, we can check the permission of the user in basepage for all pages.
ASP.NET 2.0
Master Page can be used instead of BasePage Class.

Are you trying to run it in the IDE or directly through localhost?
Try going to the properties for that particular site in IIS and under the Security tab choose the first edit button. Under there make sure that "Windows Authentication" is checked.

This seems to work:
<td[\w\W^<>](?<CaughtData>.+)</td>
The value will be stored in the CaughtData group.

Inherits System.Web.UI.Page
'Dim connString As String = ConfigurationManager.ConnectionStrings.ToString

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

see my web.config file below

you can use the following code to retrieve the application settings from the app.config.
System.Configuration.ConfigurationSettings.AppSettings("ORAConnectionString").tostring
The next problem in your code is you have to create an instance for a oledbcommand like
Dim oCmd As new OleDbCommand(Command text, connection)
try this

Hi,
How best to get application settings to initialize a property or member variable?
I have this in my constructor:
_MySetting = ConfigurationManager.AppSettings["MySetting"]);
This might fail if the user hasn't got the application setting defined. Constructor should only initialize members really so how best to write it in a constructor so that it initializes to a defined setting or another value if the setting is not defined?

If you happen to be using .net 2.0 you can use the ??
So your code would be:
_MySetting = ConfigurationManager.AppSettings["MySetting"]) ?? "DefaultValueHere";
If you are using .net 1.1 you would probably have to do something like:
if (ConfigurationManager.AppSettings["MySetting"] == null)
{
_MySetting = "DefaultValueHere";
}
else
{
_MySetting = ConfigurationManager.AppSettings["MySetting"]);
}
Hope that helps.

string mySetting = ConfigurationManager.AppSettings["MySetting"]);
if(mySetting != null)
{
_MySetting = mySetting;
}
else
{
_MySetting = "default value";
}
Theres one way.

How about this:
_MySetting = (ConfigurationManager.AppSettings["MySetting "] == null) ? "default value" : ConfigurationManager.AppSettings["MySetting"]);

how to create a link in a grid view's each row to navigate to some other page.???
|
|
|

Convert the cell you want to use to a template field then you can edit the template and put a link control inside.
|
|
|

<asp:HyperLinkField DataTextField="LastNameFirstNameMI"
HeaderText="Employee" SortExpression="LastNameFirstNameMI" DataNavigateUrlFields="EncryptedUID"
DataNavigateUrlFormatString="~/YourPageHere.aspx?id={0}" />Michael

You can read the xls file from your code then, show those data in HTML or DataGrid/Repeater or etc... just like reading data from SQL.

hi,
this is the code to do that, Dont forget to score it if it satisfies your need.
FileStream fileStream = new FileStream("c:\\Admin.xls", FileMode.OpenOrCreate, FileAccess.Read);
long len;
len = fileStream.Length;
Byte[] fileAsByte = new Byte[len];
fileStream.Read(fileAsByte, 0, fileAsByte.Length);
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.Buffer = true;
Response.ContentType = "application/vnd.ms-excel";
Response.BinaryWrite(fileAsByte);
Response.End();

Hello,
I am using Visual Studio 2003 in order to develop a setup and deployment project for a web application. Everything works fine excepting one desktop application that I have included in the setup and that have to be executed during the setup. The problem is that the setup waits for process execution and it does not complete until I close that application. The idea of the application is to stay in the system tray and not to be closed. My question is: is there a parameter that I can specify in order that the setup to do not wait for desktop application execution.
I am very familiar INNO setup and there is a flag nowait that does this trick. If anyone can point me a similarity in Visual Studio, I would appreciate it.
Thanks,
Dan.
