Fix your mail settings in your code to point to a real mail server and you will be fine.

Look up what the IP Address 127.0.0.1 is and you will have your answer.

you find out what happens when you copy code without understanding it, I guess. There's nothing wrong with googling for code, I spent the week doing that. But, once you find a snippet that says it will do what you want, you should read up and understand it so you can work on it if you need to.

Hi i am trying to count the number of button clicks in asp.net page.
i am declaring a global variable. so every time when page refreshes creating a new object..so count going to 0. So how can i save this value in the view state?
|
|
|
|
|
Hey i got the solution.. i have used cache concept.
in the page load event i have assigned some value to cache key like this
If(!Page.IsPostBack)
Cache["Count"] = 0;
then in the button click event i have casted this value to an integer and counting the button clciks. then after incrementing the value of i again assigning it to Cache Key.
Button Click Evet..
int i = (int)Cache["count"];
Label1.Text = i.ToString();
i++;
Cache["count"] = i;
|
|
|
|
|
Do want the same count for all user ? Why using Cache ? Why not session ? Cache data should be same for all user.

Hello everyone,
I am doing my final year projects in ASP.NET .In my project i need to implement a fingerprint recognition system which identifies a particular user to access the website.
I have a toshiba laptop equipped with fingerprint reader. What software i must use to interface and capture the image so that i can use these for authentication purpose?
please correct me if i am wrong.

Well, you can't do this in ASP.NET. You CAN perhaps do it with a java or .NET component that's embedded in an ASP.NET website.

hello
I am studying asp.net and I have one assignment to create small content management system still I am not getting any were but now I have used VWD help to find out about it but it's not the same thing i am looking for but I found WebPartManager control so I read that artical and then start droping controls on web page and follow all the instrutions but now I am getting this SQL Error and I have no idea where it comes from because there is not even a single sql database in this application at this stage but I am going to use it after getting that stage, on web form there is one WebPartManager control two WebPartZone but if i remove this two controls and then i try to run application then it runs without any problem and this is the error as bellow
Server Error in '/TestWebSite' Application.
--------------------------------------------------------------------------------
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
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.
SQLExpress database file auto-creation error:
The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:
If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database.
Sql Server Express must be installed on the machine.
The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

As I have already told you web parts need SQL Express to store personalized and membership information. This is
ASP.NET SQL Server Registration Tool (Aspnet_regsql.exe)
aspnet_regsql command is used to create all the tables and procedure for that membership and personalization information to that database.
You can Explore aspnet_regsql Here[^]
To Run
C:\%windir%\Microsoft.NET\Framework\<versionnumber>\aspnet_regsql.exe</versionnumber>
A wizerd will come , and you just follow the steps and then run your application with web parts !!!
let us know if any issue !!
cheers,
Abhijit
