How to get Mouse Cursor Position

There is no Certain way to find the Cursor position of mouse within the Browser.
W3c standards say that you can get the position when event is triggered by event.clientX and same for clientY. to find out the Distance between left n Top

side.

Its works fine on IE6 , Netsacape , Firefox , Opera 7+ and all othe browser.
in IE uses two Different ways to scroll the position of pages they are using Document.body.ScrollLeft and same for the ScrollTop. this is in Before version

of 6
Some of the Browser used PageXOffset & PageYOffset.

Here is Function call MouseX() and MouseY() which can calculate the X and Y Co-ordinates of same,



function mXbar(action) {
if (action.pageX) return action.pageX;
else if (action.clientX)
   return action.clientX + (document.documentElement.scrollLeft ?document.documentElement.scrollLeft :document.body.scrollLeft);
else return null;
}
function mYbar(action) {
if (action.pageY) return action.pageY;
else if (action.clientY)
   return action.clientY + (document.documentElement.scrollTop ?document.documentElement.scrollTop :document.body.scrollTop);
  else return null;
}

there are few more ways to calculate the cursor position event.ScrenX or event.screenY
these feature are not thee in Netscape4 and IE old version, but in new version of ie 7 + they have all such feature,

Handle Master page Click Event on Content Page

In ASP.net2.5 there a new concept knowns as Master Page , with the help of that you can
customize you'r repeteative work. Create a one Master page and use that page on all the other pages. Its really very good tech to crear your coding and clear your logic also.

now sometime we have a LinkButton define on Master page which can be work as a "Link to the Customer information " and this can be change depend on customer role. and that LinkButton action we want in the Contenet page.

Supoose we have LinkButton call "linkFromMasterPage" on Master Page. Here is small code which can helps you to do same .

C#--


  Public LinkButton linkFromMasterPage(){

        Get {

            Return linkFromMasterPage;

        }

    }

Now next Process is reference the Master Page as a casted object in the Content page.
here CusMasterPg is a Class of Maste Page.


   CusMasterPg cm = ((CusMasterPg) (Master));

Now you can easily access the all the methods, public properties of Master page class.
so next stpe is handle the button Event on your content page


    protected void Page_Load(object sender, EventArgs e)
    {
      If (!(IsNothing(cm))) { 

        cm.linkFromMasterPage.Click += New EventHandler(linkFromMasterPage_Click);

      }
    }

next thing is define actual method handle on your page.



  Protected void linkFromMasterPage_Click(Object sender, System.EventArgs e){

        // write Perform Business Logic Here
    }

thats all , you can do same thing for User Controls also for Handle Master page Click Event on Content Page.

ASP Format Date and Time

while coding on ASP we required date and time most of the time, how to get this is very basic and well known to the most of the Programmers, but how to get the only specific date , time in required format is a main task ,

for that we have inbuild function call FormatDateTime() .

now we very well knows if we want to get current date and time then we can use now()


  <%dim TodayDnT
    TodayDnT = now()
  %>

if you want the Result of same then use <% Response.write(TodayDnT) %>
so it will return result as : - 8/5/2009 12:11 PM

now we have the option to format that
1. Using 0


 <% 
 Response.write FormatDateTime(TodayDnT,0)  
 %>

Result : - 8/5/2009 12:11:10 PM

2. Using 1


 <% 
 Response.write FormatDateTime(TodayDnT,1)  
 %>

Result :- Wednesday, August 12, 2009 (long date )

3. Using 2


 <% 
 Response.write FormatDateTime(TodayDnT,2)  
 %>

Result: - 8/5/2009 (short date)

4. using 3


 <% 
 Response.write FormatDateTime(TodayDnT,3)  
 %>

Result : - 12:11:10 PM (long time)

5. using 4


 <% 
 Response.write FormatDateTime(TodayDnT,4)  
 %>

Result : - 11:10 (current time in 24 format (hh:mm)

If you want to change the Date and Time according to international location then
use session.lcid property

Ex : - <% session.lcid=1036 %>
which will set the Date n Time in French Format

Debugging for ASP.NET Applications

If you are using Visual Studio2005 and if you want to enable debugging in the project properties Then Follow the Stpes
In VS 2005, use the <Project> Property Pages to set project properties :
here is the way to do
- Right click on Solution Explore of Project,Then Open the Property Pages by and selecting Property Pages.
- Select Start Option tab
- Under Debuggers, make sure the ASP.NET box is selected.

You can also enable the debugging using web.config file

- Inside the <compilation> tag, you will create the debug attribute.
- specify attribute as a "debug", not "Debug" or "DEBUG" because the are very Case-Sensitive so please take care of that.
- Set debug option as a true.

Here is a sample Web.config file



<configuration>
<system.web>
<compilation defaultLanguage="VB" debug="true" numRecompilesBeforeAppRestart="15">

<compilers>
<compiler language="C#;Csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,system, Version=1.0.5000.0, Culture=neutral, 

PublicKeyToken=b77a5c561934e089" />
<compiler language="VB;VBScript" extension=".cls" type="Microsoft.VisualBasic.VBCodeProvider,system, Version=1.0.5000.0, Culture=neutral, 

PublicKeyToken=b77a5c561934e089" />
</compilers>

<assemblies>
<add assembly="ADODB" />
<add assembly="*" />
</assemblies>

<namespaces>
<add namespace="System.Web.UI" />
<add namespace="System.Web" />
<add namespace="System.Web.UI.WebControls" />
