This is a trend of software developer by Google.

Compare .Net,Java,PHP

Compare C#,VB

Compare MCSD,MCPD,MCSE,MCITS

Compare Ajax.Net,ASP.Net Ajax

Compare Planet source code,Code Project,DevX

Compare MySQL,SQL Server,Oracle

By the way this is not benchmark popular trends.Because Google trends can't separate java platform from java Island or java coffee and in other case too.

Design Exception Handler Pattern

2007-08-13T21:38:00.000-07:00

When we write application we should handle exception for block Application Exception when it occurs, our application may crash.

.Net developer regular design exception as this.

Try

‘statement for operation

‘e.g’

Dim CN as new Oledb.OledbConnection(strConnectionString)

CN.Open()

‘other statement for operation

Catch ex as Exception

‘statement for handler exception

‘e.g.

ModuleLogError.WriteLog(ex)

Finally

‘This statement will execute even code have exception or not

CN.Close

End try

This rule will help for design better structure of handle exception.

1. Check exception may occur before Exception

e.g. DivideByZeroException,ArithmeticException …

This below is a sample code

Try

‘’’

Catch(Ex as DivideByZeroException)

‘’’

Catch(Ex as ArithmeticException)

‘’’

Catch(Ex as Exception)

‘’’

End Try

2. Keep module detail to have occur exception

In a moudule we handler exception we shuld send information about module have occure exception e.g. Modulename,section of section

Dim strModuleName as string= “DAC.Customer” ‘This variable outside method because we shared it multiple method

Private Sub SaveData()

Dim strMethodName as string=”SaveData”

Dim strSection as string = “Begin Module”

Try

strSection = “Operation 1”

‘statement for operation1

strSection = “Operation 2”

‘statement for operation2

‘other statement for operation

Catch ex as Exception

ModuleLogError.WriteLog(ex,strModuleName,strMethodName,strSection,)

Finally

‘This statement will execute even code have exception or not

CN.Close

End try

End Sub

3. When we loop operation loop should in exception

e.g.

if your code is look like this:

dim I as integer

for I = 1 to 100

Try

‘statement

Catch ex as Exception

‘statement for handler

Finally

‘statement for release unsafe resource and other benefits

End try

It should refractor your code as below:

Try

Dim I as integer

For I = 1 to 100

‘statement

Catch ex as Exception

‘statement for handler

Finally

‘statement for release unsafe resource and other benefits

End try

It is have high performance than before.

4. Avoid use exception in case we can handle it by operation checking

e.g.

if(Num1 = 0) then

MessageBox.show(“Value cannot be 0”)

Exit sub

end if

dim dblResult = Num2 / Num1

instead

try

Dim dblResult = Num2 / Num1

Catch ex as DivideByZeroException{

MessageBox.Show(“Value cannot be 0”)

End Try

Because exception is expensive, we should avoid in a case we can handle it

5.When you application design for contact with another layer (some dll ,e.g. BC layer, DAC layer) you may not throw exception, but should keep exception for client to handle it.

e.g

This is a DAC.

Namespace DAC

Public Class Customer

Dim currentException as ApplicationException

Public Sub AddData()

Try

‘’’ Statement

Catch Ex as Exception

Me.CurrentException = Ex

End Try

End Sub

End Class

End NameSpace

And this is a client code.

Dim cCustomer as New DAC.Customer

cCustomer.AddData

if(Not isnothing(cCustomer.currentException ))

‘code for handler exception of dac

‘e.g.

‘MessageBox.Show(ex.Tostring) ‘ for winform

‘Me.lblShowError.InnerText = ex.ToString ‘for web form

‘code for write log error

End if

6. In development phase you should display detail about exception instead hardcode wording for user

e.g.

Try

‘Code for Add data

Catch Ex as Exception

MessageBox.show(ex.toString)

Instead

MessageBox.show(“Error:Please enter againg”)

End Try

This will help you easy to find the problem, and then you pass development phase you may change wording to friendly word for user. Or you may send both error message and friendly word to user , but you should care about security issue.

7. Desing your own exception

If you wish to design you exception. It is easy to do, you just create a new class and inherit from ApplicationException

How i hide left navigate and right navigate YUI Calendar ?

2007-08-05T23:30:00.000-07:00

In my project i must use YUI Calendar control for build static calendar show to user.
but I can't find the solution to hide left navigate and right navigate.
after i search yahoo api , I don't found any thing.

but now,after i try to hack calendar.js
I know the solution for hide left navigator and right navigator

First solution
1.Open calendar.js this file is in yui2.3.0\yui\build\calendar\
2.you just go to line 2321 and you will see javascript code for about render left and right navigator
then you just comment this code
you must separate comment to two group because you should not comment code for display month name

/*
if (renderLeft) {
var leftArrow = this.cfg.getProperty(defCfg.NAV_ARROW_LEFT.key);
// Check for deprecated customization - If someone set IMG_ROOT, but didn't set NAV_ARROW_LEFT, then set NAV_ARROW_LEFT to the old deprecated value
if (leftArrow === null && YAHOO.widget.Calendar.IMG_ROOT !== null) {
leftArrow = YAHOO.widget.Calendar.IMG_ROOT + DEPR_NAV_LEFT;
}
var leftStyle = (leftArrow === null) ? "" : ' style="background-image:url(' + leftArrow + ')"';
html[html.length] = ' ';
}

*/
html[html.length] = this.buildMonthLabel(); /* This line is for display Month don't comment it */
/*
if (renderRight) {
var rightArrow = this.cfg.getProperty(defCfg.NAV_ARROW_RIGHT.key);
if (rightArrow === null && YAHOO.widget.Calendar.IMG_ROOT !== null) {
rightArrow = YAHOO.widget.Calendar.IMG_ROOT + DEPR_NAV_RIGHT;
}
var rightStyle = (rightArrow === null) ? "" : ' style="background-image:url(' + rightArrow + ')"';
html[html.length] = ' ';
}
*/
3.and then you just save calendar.js when you create Calendar you don't see left navigate button and right navigate button.

But this solution will make all of calendar of your app don't display left and right navigate button except you will separate calendar.js.
well I think we shoul have a better solution

Lets'go to second solution

Second solution.
1.like first solution.You just open calendar.js
2.you just set id of both left and right navgate button in this case I name ALeft and ARight.
if (renderLeft) {
var leftArrow = this.cfg.getProperty(defCfg.NAV_ARROW_LEFT.key);
// Check for deprecated customization - If someone set IMG_ROOT, but didn't set NAV_ARROW_LEFT, then set NAV_ARROW_LEFT to the old deprecated value
if (leftArrow === null && YAHOO.widget.Calendar.IMG_ROOT !== null) {
leftArrow = YAHOO.widget.Calendar.IMG_ROOT + DEPR_NAV_LEFT;
}
var leftStyle = (leftArrow === null) ? "" : ' style="background-image:url(' + leftArrow + ')"';
html[html.length] = ' ';
}

html[html.length] = this.buildMonthLabel();

if (renderRight) {
var rightArrow = this.cfg.getProperty(defCfg.NAV_ARROW_RIGHT.key);
if (rightArrow === null && YAHOO.widget.Calendar.IMG_ROOT !== null) {
rightArrow = YAHOO.widget.Calendar.IMG_ROOT + DEPR_NAV_RIGHT;
}
var rightStyle = (rightArrow === null) ? "" : ' style="background-image:url(' + rightArrow + ')"';
html[html.length] = ' ';
}
3.In a page you wish build calendar and wish to hide left and right navigator.
you just write this code

I use setTimeout because I want to object calendar loaded.
when first excute function HideNav if element ALeft or ARight dosen't loaded.
it will setTimeout again and again until ALeft and ARigh loaded and hide it.

Now.I think this solution work for me.
But you may have a problem.
e.g. When your page have more than one calendar and you want to hide navigate button of some calendar.and now each navigator button have same id (ALeft and ARight)

Dataset Interview

2007-08-02T22:14:00.000-07:00

Q:What is dataset ?
A:Dataset is a database on ram.
dataset contain number of datatable.
datatable contain number datacolumns and datarow collection.
Each datatable may have a primary key and foreign key and have a data relation to other datatable.
Each datacolumn have datatype.
Each datarow contain record of datatable.
dataset itself not know about source of data.
data to fill in dataset may from many kind of RDBMS,textfile,XML file, of just create data in memory from code.

Q:How i add new row to datatable ?
A: You just simple create new row a reference to a NewRow() method of datable.
new row is a depend from datatable while you not add it.
When you add It.It will add to last row of datatable.
'sample code
dim DR as DataRow = DS.tables("Customer").NewRow()

'set each field
DR("CustomerName") = "John doo"
DR("CusPhone")= "555-555-555"
...

DS.tables("Customer").Rows.Add(DR)

Q:How DS.Tables("Mytable").Clear different from DS.Tables.Remove("MyTable")
A: Clear() method of datatable make datable delete all row.but structure of datatable is not delete too.
in this case DS will contain datatable Mytable and Mytable will contain each datacolumns.It is similar Delete MyTable in T-SQL.

But Method Remove() of Dataset.Tables is remove datatable exctracly.It is similar DROP statement in T-SQL

Q:I have a datarow ,and i want to add to two datable.How i do that ?
A: you must use method ImportRow() of datatable instead .Rows.Add().

Q:How i retrive data from database to dataset ?
A:ADO.Net have many method to retrive data from database
but this is one of easiest method.

'you just create new DataAdapter and set SQL statement for retrive data do you want
'and set Connection object
'behind the scence DataAdapter will retrive data from SQL statement throught Connection object
'and then you just use Fill method ,first parameter is dataset object, second is table name do you want
dim DA as New Oledb.OledbDataAdapter("Select * from Customer",conObj)
DA.Fill(DS,"Customer")

Q:How i update data from dataset to database ?
A:This solution similar when you want to retrive data from database
dim DA as New Oledb.OledbDataAdapter("Select * from Customer",conObj)
dim CB as New Oledb.OledbCommandBuilder(A)' you just add this line for create Command builder and reference to DataAdapter
DA.Update (DS,"Customer") ' and then update dataset table Customer throught Update method

Behind the scence CB object will create Insert,Update,Delete SQL statement from schema
if you serious performance issue you should create SQL statement by manual
This example just show you how to update by simplest way.

Q:Are datatable must retrive data from database ?
A:NO. Datatable can create datafrom void.
you can create new datatable and create new datacolumn.and then you use it with out database.
'e.g.
dim DT as new Datable

DT.DataColumns.Add(new DataColumn("ID",type.GetType(System.String)))
DT.DataColumns.Add(new DataColumn("Name",type.GetType(System.String)))

'and then you may add a datarow from Initialvalue of datatable

Q:How i use Dataset read XML file ?
A:Yes. You just use ReadXML() Method from Dataset and you can Save XML data from dataset to XML file,just use WriteXML() Method.

Q:Why i can retrive data from database to dataset and i can insert new data too.But I can't Update or delete data ?
A:May your table in database don't set Primary key.When you use dataadapter for update.It must you Primary Key for generate SQL statement.
In case of select or insert ,it not have problem but in case of update or delete it will crash.

.Net Tips and Trick Smart Query string

2007-06-26T23:03:00.001-07:00

1.Smart Query string.
you should use smart query string for strong type purpose.

Private ReadOnly Property CusID() As Integer
Get
If IsNothing(Me.Request.QueryString("CusID")) Then
Return 0
End If

If Not IsNumeric(Me.Request.QueryString("CusID")) Then
Return 0
End If

If CInt(Me.Request.QueryString("CusID")) > 0 Then
Return 0
End If

Return Me.Request.QueryString("CusID")

End Get

when you want to use Query string CusID you just type

me.CusID

instead

cint( Me.Request.QueryString("CusID"))
