Google Trends about .Net developer
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
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
‘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
next
It should refractor your code as below:
Try
Dim I as integer
For I = 1 to 100
‘statement
Next
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

Ajax Tabcontrol inside Update panel can't find CSS
I use Ajax Tabcontrol inside Updatepanel
and each tabcontrol contain Usercontrol
each Usercontrol reference CSS file
when first run It fine.
but when I update data.
Page display is crash.
I found solutino fo solve this problem
you just copy code for reference to css file in usercontrol
to page
How i hide left navigate and right navigate YUI Calendar ?
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
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.
