Microsoft SQL Server T-SQL date and datetime formats

Microsoft SQL Server T-SQL date and datetime formats
– Date time formats – mssql datetime 
– MSSQL getdate returns current system date and time in standard internal format
SELECT convert(varchar, getdate(), 100) – mon dd yyyy hh:mmAM (or PM)
                                                                   – Oct  2 2008 11:01AM

convert web asp.net from .net framework 2.0 to .net framework 3.5 fix Ajax return msg.d

เพิ่ม tag javascript ในหน้าที่มีการเรียกใช้ ajax

$.ajaxSetup({
            dataFilter: function (data) {
                return JSON.stringify($.parseJSON(data).d);
            }

        });

เนื่องจาก project มีการเรียกใช้หลายที่ ทำให้แก้ไขยาก ถ้าใช้วิธีนี้ไม่ต้องแก้ไข code เก่าเลย ลดงาน ลดเวลา ไม่กระทบงานเก่า

Linq OrderBy Extension

ในการพัฒนาโปรแกรม ด้วย ASP.net ต้องมีการQuery ข้อมูลมาแสดงในGridView ซึ่งต้องมีส่วนของการ Sort Data แน่นอน และถ้าเราใช้ LinQ ละ? ผมจึงนำ Extension Method ใน LinQ นำมาฝาก
รูปแบบการเรียกใช้งานทำได้ดังนี้

list.OrderBy("SomeProperty");
list.OrderBy("SomeProperty DESC");
list.OrderBy("SomeProperty DESC, SomeOtherProperty");
list.OrderBy("SomeSubObject.SomeProperty ASC, SomeOtherProperty DESC");

Prevent Remember My Password , Disable Remember My Password on brower

ในหน้าเว็บที่ต้องกรอก UserName & Password เมื่อทำการ submit แล้ว Brower จะถามว่าต้องการบันทึกหรือไม่
      เมื่อเราทำการกด บันทึกBrower ก็จะจำuser และ รหัสผ่านที่เรากรอกไป
ซึ่งทำให้ผู้ที่เข้ามาเปิดเว็บคนถัดไปสามารถใช้ ข้อมูลที่เก็บไว้ในที่นี้ log in เข้าไปได้

วิธีการป้องการ การจำในส่วนนี้ ทำได้ดังนี้
(Disable Remember My Password)
เพิ่ม tag
              <div style=" visibility:hidden; width:0px; height:0px;">
                    <input id="txtpus"  type="text" />
                    <input id="txtusper" type="password" />
