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

Ohhh... Soryy about that.... that's not from command prompt. you have to run for Framework dir
C:\%windir%\Microsoft.NET\Framework\<versionnumber>\aspnet_regsql.exe</versionnumber>
When you run that command, In first screen , do nothing , Next -> in second screen Give the database server name and Authentication Settings and Select Database from database list [ Create a new database first then Select that one ] . Then Next , Then Finished .
That's All !!!

Hi,
I have a trusted site (https), and I am trying to open the attachment through
window.open('https://IPAddress/VirtualDirectiory/SomeFileName.txt');
This is not happening. But when I try with "http" I am able to open.
Any one help me in this.

Maybe the popup opens and closes immediately, Explorer's download warning may couse this. try to change the settings in explorer security section Automatic propmpt for downloads to enabled. Or try to add http site as trusted. Lets see if the problem continues.

Just provide a link to the file, or just write the file from the server down to the client with the right content type in the header, so that Word will open it on the client.
