I don't know how you manage your passwords but I am finding it difficult to keep track of all my passwords. From often changing bank passwords to credit card PINs, it is really difficult to keep these details secure and accessible.
I came across two tools which can really simplify life:
(1) F-Secure Key
It is a light-weight tool which you just install on your PC or Smartphone and set one master password. This master password is used to encrypt the data file using AES-256. The data file is stored on your PC. You will ask there are several tools which perform similar tasks and are freely available. Yes, but what makes F-Secure Key different is that it can synchronize your protected data across devices like smartphones. This feature is not FREE and available with a minimal subscription fee. Once you create F-Secure account and subscribe to sync feature, your passwords can be accessed on your smartphone. F-Secure Key mobile app. is available FREE on Google Play Store.
F-Secure Key can also auto-fill your passwords when you open websites.
(2) AVG Vault
It is a mobile app which you can install on your Android/iOS phone to store passwords. To use AVG Vault, a 4-6 digit PIN is required which acts as a master password. Once you have created this PIN, it is used to encrypt your data and sync the encrypted backup to either Dropbox or Google Drive.
One cool feature of AVG Vault is to automatically capture face from front camera if repetitive failed attempts are made to login. This image is mailed to the registered email ID.
Both F-Secure and AVG Vault are trusted names in the area of data security.

In a situation I had to create a Data Table manually and add columns and rows to it. Later I wanted to search for a row in this Data Table using LINQ. As soon as LINQ code was fired I got this error: "Specified cast is not valid". Below I am sharing a sample code to simulate this problem and will tell you how to get rid of this error in this particular situation I mentioned above.
public partial class _Default : System.Web.UI.Page
DataTable dt = new DataTable();
protected void Page_Load(object sender, EventArgs e)
DataRow row = dt.NewRow();
row = 1;
row = 2000;
protected void GetRecord(int RowId)
var results = from row in dt.AsEnumerable()
where row.Field<int>("RowId") == RowId
string FetchedRowId = results.ToArray().ToString();
If you execute this code, you will get this error:
The root of this error lies during the creation of columns for the Data Table. Do you notice these lines:
Here if you don't specify the Type of column, the default type considered is 'string'. Mentioning the default type of each column solves this issue:
