getting basic data types using reflection than nullable

Share |

While using class properties to use for data base connectivity, i.e. LINQ TO SQL, I was facing issue for nullable types. I was using Reflection to fetch property type names, but for NULLABLE properties it use to send me property type name as NULLABLE`1. I was suppose to use following switch case (Determine Nullable properties via reflection)

public static string getJSType(PropertyInfo propertyinfo)
        {

//GetCoreType function returns Property type.
switch (GetCoreType(propertyinfo.PropertyType).Name.ToUpper())
                {
                    case "INT16":
                        return "number";
                    case "UINT16":
                        return "number";
                    case "SHORT":
                        return "number";
                    case "USHORT":
                        return "number";
                    case "INT32":
                        return "number";
                    case "UINT32":
                        return "number";
                    case "INT":
                        return "number";
                    case "UINT":
                        return "number";
                    case "INT64":
                        return "longnumber";
                    case "UINT64":
                        return "longnumber";
                    case "LONG":
                        return "longnumber";
                    case "ULONG":
                        return "longnumber";
                    case "DECIMAL":
                        return "decimal";
                    case "DOUBLE":
                        return "float";
                    case "BIGINT":
                        return "longnumber";
                    case "STRING":
                        return "text";
                    case "DATETIME":
                        return "datepicker";
                    case "BOOLEAN":
                        return "flag";
                }
            //}
            return "text";
        }

To determine type of NULLABLE properties via reflection, I used following function GetCoreType

 private Type GetCoreType(Type type)
        {
            if (type.IsGenericType &&
                type.GetGenericTypeDefinition() == typeof(Nullable<>))
                return Nullable.GetUnderlyingType(type);
            else
                return type;
        }

Find Type of Nullable Properties via Reflection. Determine type of Nullable properties view Relection. While using reflection get core property type of nullable properties.

The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. Solved...

Share |

While working with Asp.NET and Membership, using MS SQL 2008 R2 I came across following error. My web application was working perfect on my local machine but when I hosted it on remote server I got following error.

The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.

After R&D I had came across three possible solutions "WHICH I THINK ARE RIGHT, AS THEY WORKED FOR ME IN DIFFERENT SCENARIOS."

1. Check "aspnet_SchemaVersions" table in database and make sure CompatibleSchemaVersion is set to "1" for all the Features (e.g. common, membership, role manager etc) available in table. Also make sure IsCurrentVersion column values are set to 'True" for all Features.
2. In Web.Config, and aspnet_Applications table check if application Name is matching or not. Application name in web.config's Membership>Providers, Profile>Providers, RoleManager>Providers are matching with application name in database.
3. In Membership>Provider I had "AspNetSqlMembershipProvider" type as type="System.Web.Security.SqlMembershipProvider" which I modified (after referring to some articles online) to type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

Application worked for me when I checked all these things and made changes in my application.

Cannot connect to local SQL Server Express 2008 R2

Share |

Some times while using SQL server R2 on local machines we get a connection error something looking like

TITLE: Connect to Server

Cannot connect to (local).

ADDITIONAL INFORMATION:

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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)

To deal with it, there are two things we need to check

1. Try this as your server: .\SQLEXPRESS
2. This error occurs if SQLEXPRESS instance is not started. To verify the service is started or not run services.msc and look for  "SQL Server (SQLEXPRESS)" service, status should be "Started", if it is not, try to start it manually.

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException

Share |

While working on Asp.Net application with Master Pages, Child pages and web user controls getting following error is very common. Which is related to Events related to Web user controls, e.g. Button click event...

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument.  Event validation is enabled using  in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

In such cases as error says we simply have to disable EventValidation in @Page directive and error disappears.

<%@ Page EnableEventValidation="false" %>

OR enable it for whole application by modifying it in web.config file

<%@pages enableeventvalidation="false">
<%@/pages>

Textbox with background image using CSS

Share |

We can use CSS To make stylish textboxes like rounded corner textbox or textbox with some image inside. Rounded corner text box is like following image.

To make rounded corner textbox we use following logic. We will put textbox in some wrapper layer i.e. div tag and apply style to wrapper layer.

Now style applied to wrapper div tag is as follows

.tt-wrapper
 {
 background-image:url('images/user_box.png');
 margin:0;
 width:255px;
 height:35px; 
  }

In above style user_box.png is a background image (check following image.)

 Then we apply style to fit the textbox with in wrapper div class.

.tt{
 width:240px;
 height:25px;
 margin:5px 0 0 8px;
 border:none;
 background:none;

Javascript Find Arguments Passed to a Function

Share |

While working on Javascript optimization we can always use some functions having variable number of arguments.

E.g. if we come across a situation where we have to use one function to toggle visibility of the objects, but depending on clients input number of objects which needs to hide/show varies. In this case we can write a function as below where number of parameters can any variable.

//Assumption 0th parameter is boolean 

 function toggle() {
        var args = toggle.arguments
        for (v = 1; v < args.length; v++) {
            obj = window.document.getElementById(args[v]);
            if (args[0]) obj.style.display = "";
            else obj.style.display = "none";
        }
    }

We can use this type of functions to minimize size of javascript before optimizing it.

Logout User In Asp.net Membership

Share |

While developing usermanagement based web application using Membership provider, many times we come across some trivial issues or queries as follows

• formsauthentication.signout not working
• Using formsauthentication.signout
• logout user programmatically
• Check user date subscription and log out if user is not valid.
• programmatically logout in asp net
• Logout user in asp.net Membership

Solution for all above queries is as follows

FormsAuthentication.SignOut();
  Session.Abandon();

 // clear authentication cookie
 HttpCookie frmcookie = new HttpCookie(FormsAuthentication.FormsCookieName, "");
 frmcookie.Expires = DateTime.Now.AddYears(-1);
 Response.Cookies.Add(frmcookie);

 // clear session cookie if we use any
 HttpCookie sessioncookie = new HttpCookie("ASP.NET_SessionId", "");
 sessioncookie.Expires = DateTime.Now.AddYears(-1);
 Response.Cookies.Add(sessioncookie);

 FormsAuthentication.RedirectToLoginPage("v=SubscriptionExpired");

Above code signout the user, remove all the Cookies set. Forms Authentication.RedirectToLoginPage uses settings in web.config file. We can pass Querystring to the function so that we can show proper Messages.
