Using Resize Property to Change the size of a range

The Resize property enables you to change the size of a range based on the location of the active cell.
You can create a new range as you need it.

For Example

Sub rngresize()

ConnectionString Briefing(Used in SQL Server connectivity)

In computing, a Connectionstring is a string that specifies information about a data source and the means of connecting to it. It is passed in code to an underlying driver or provider in order to initiate the connection. Whilst commonly used for a database connection, the data source could also be a spreadsheetor text file.  ConnectionString property can be set only when the connection is closed. The connection string is parsed immediately after being set. If errors in syntax are found when parsing, a runtime exception, such asArgumentException, is generated. Other errors can be found only when an attempt is made to open the connection.
The connection string may include attributes such as the name of the driver, server and database, as well as security information such as user name and password.
For Reference:
www.connectionstrings.com

For example:
 con_string = "DRIVER={MySQL ODBC 3.51 Driver};user=internalros;password=internalros;database=TBS; server=206.71.169.000;option=18475"
ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Data Source=NEW\SQLEXPRESS;"

ODBC-it is designed for connecting to relational databases.
However, OLE DB can access relational databases as well as nonrelational databases.

Brief Introduction to Sensitivity Analysis

A technique used to determine how different values of an independent variable will impact a particular dependent variable under a given set of assumptions. This technique is used within specific boundaries that will depend on one or more input variables, such as the effect that changes in interest rates will have on a bond's price.

One of the finest features in Microsoft Excel is sensitivity analysis using either a table (Excel 2003) or 'What-if' in Excel 2007. Suppose you want to start a cybercafe or a restaurant in a new mall. You have done a study on the footfall and the kind of people who visit the mall. You have also found out about the business atmosphere, security and rent or the outright purchase price. You also know the rates in the market that other businesses are charging, let's say, for surfing the net per hour. You then estimate your capital costs like doing up the cybercafe and the price of the computers. You also use the Excel spreadsheet to estimate and calculate the number of people you'll need to run the show and the amount of salaries you'll have to pay. You have also estimated other variable costs like electricity and phone.

From the above data in the Excel worksheet you can calculate your total monthly or yearly costs. Now based on a certain price that you will charge the customers, number of computers and working hours you can calculate your revenue per month or per year. From the data of revenue and income you can easily calculate the profit. Till now everything was easy to implement in Excel.

Now you decide to find out how your profit can vary if you vary the charge per hour or the number of people who will visit your cybercafe or establishment. Of course, you cannot charge what you want but you can get a good estimate by observing what others are charging and what quality of service and environment they are providing.

Arranging all your data properly, click on 'Data' in the ribbon in Microsoft Office 2007 or 'Data' in the menu bar in Excel 2003. In Excel 2007 select 'What-if' analysis and finally 'Data Table...'. In the popup window in the 'Row input cell' type the data that you have input horizontally next to the profit and in the 'column input cell' write down the price and vary it it by 1% 0r 2% so that that Excel can perform an analysis for, say., $0.5 per hour charge for a cybercafe to $1.5 per hour. The horizontal values can be the number of people per hour or month or year that will visit the shop and keep on varying the values by a certain estimated percentage. Click 'OK' and you can see how your profit varies with the number of customers and the price you charge. This is also known as a two variable table because you calculated the changes in your profit based on two parameters - price and number of customers.
