### Measure Ajax call duration till page is rendered (including screen paint time)

Hi,

I am using an ASP.Net AJAX application and I need to measure the performance of the AJAX call from the time it is invoked till page is rendered, including screen paint time.

I am using an update panel.

The screen paint time is critical since i want to record the time taken to render the output as well.

### Round off time to the nearest minute

How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

### Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

### Date and Time Functions in SQLSERVER

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

1 DATEPART Function
2 DATENAME Function
3 DAY, MONTH, and YEAR Functions
4 GETDATE and GETUTCDATE Functions
6 DATEDIFF Function
7 More SQL Server Functions

### Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

### How to programmatically add controls to Windows forms at run time by using Visual C#

Create a Windows Forms Application
Start Visual Studio .NET or Visual Studio 2005 or a later version, and create a new Visual C# Windows Application project named WinControls. Form1 is added to the project by default.
Double-click Form1 to create and view the Form1_Load event procedure.
Add private instance variables to the Form1 class to work with common Windows controls. The Form1 class starts as follows:

### .NET 4 Web Application Startup Time

I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.

### Built-in Functions - Date and Time Functions

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

### Essential SQL Server Date, Time and DateTime Functions

The essential date and time functions that every SQL Server database should have to ensure that you can easily manipulate dates and times without the need for any formatting considerations at all.

### Date/Time Conversions Using SQL Server

There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you.

### huge number of data from database ... so how to minimize load time

Hi ...

I have used the above method to configure my crystal report ...

Its working fine , But i have huge number of data in database ....

So , it take long time to load the report ...

So , i have decided to show only the last 50 records inserted into the database , not all the 500 records to be loaded every time.

Plz help me with this issue  ...

Also , Plz explain me abt index legend in crystal report.

### Can this code be setup to run against the whole database instead of just 1 record at a time?

We have made some changes to this code to start capturing 1 new field of data and updating it as new records are added. But there is currently about 120,000 records more or less.. those records of course dont have the new field populated with anything..

We would like to run this logic that already in place and run it against the tables to update the fields 1 time. I think to make it easier, if it can be setup to expect the "valueTwo" variable, so that we can run it againt the individual codes instead of doing all the records at one time.. there are codes that only have a few records, so it would be best to test initially against the small code group.

thanks.

```
strSqual = "insert into trans (trans_type_name, trans_date,sys_id,mod_user_id,show_ind, remoteCode, techName) values('" & valueTwo & "','" & TransDate & "',"&strSystemID&", 1,'T', '" & dbQuote(strUser) & "', '" & strTechName & "')"

getStaticRecordSet(strSqual)
'get the new transaction_id out for just inserted alarm
strSqual = "select max(transaction_id) as transaction_id from trans"
set rst = getStaticRecordSet(strSqual)```

### SqlDataSource how to change the stored procedures at run time

Hi

Is it possible to change the select, insert and update stored procedure of an SqlDataSource at run time. I don't mean to change the definition of the stored procedure, but I mean to change the assignment, i.e. To change the select stored procedure from "selectSP1" to "selectSP2" at run time. Is it possible?

Regards

Dimitris
