Login Form using sql database c# -

-

I am trying to create a sign up page. You enter the username and password and save it in the SQL database.

Note: As long as I add another column (password), the matter works.

This is a password code (username is the same): 

  static public zero deletion (string _Password) {try {connection.Open ()} SqlCeCommand commandInstert = New SqlCeCommand ("Include [table] values ​​(@ password)", connection); Command insert Parameter. Add ("password", password); CommandInsert.ExecuteNonQuery (); } Hold (SqlCeException Expaction) {message box. Show (Excl. ToString ()); } Finally {connection.Close (); }}   
 and this button settings are:  
  Private Zero Button 1_Click (Object Sender, EventArgs e) {if (deleteBox.Text! = " } {SQLFunctions.Insert (insertBox.Text); SQLFunctions.delete (deleteBox.Text); SQLFunctions.Refresh (this.dataGridView1); } Other {message box. Show ("login failed"); }}   
  Thanks    
 
 
 I think you need to make some changes to your code like this  
  SqlCeCommand commandInsert = new SqlCeCommand ("INSERT IN [TABLE] VALUES (@username, @password)", connection );   
 You should pass two parameters because you have two fields now DB and if you do not want to give a username, then you should specify this way  < Pre>  SqlCeCommand commandInsert = new SqlCeCommand ("INSERT [TABLE] (password) value (@ password)", connection);   
 and  
  command insert. Parameter. Add ("password", password);   
 It should be written as:  
  Command insert.Pameters.ad ("@ password", password);   
 And to pass the values ​​of this parameter, you can do this  
  command. Parameter. Advait Value ("@ password", insertBox.Text);

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
