What is 'Custom Format' ?:
Microsoft Office Excel provides many built-in number formats, but in some cases they do not meet our needs, we can customize a built-in number format to create our own.

Why 'Custom Format' and not 'Conditional Formatting'?: because to cure 'Common Cold' we go to doctors not surgeons. Exactly, when there is a simple and robust way then why to go otherwise. There are many benefits of using custom format including these:
1. Less overhead than Conditional Formatting.
2. Values can be used easily in formulas (Less manipulation required).
3. Charts looks better with custom colored labels/axis.
4. Works on all versions of Excel.
and many more which you can figure out using your innovative mind after reading this article.

SHRINK REDUCE EXCEL FILE SIZE

If minor or little changes in your excel workbook bloated its size to 200% and above then it's a serious issue but not worry issue as it has solution.

Understand the problem: First understand the difference between 'Excel Default Last Cell' and 'Actual Last Cell'. When you do 'Ctrl+End' to find last cell, you'll reach to 'Excel Default Last Cell' which may be the 'Actual Last Cell' or beyond the 'Actual Last Cell'. The more beyond 'Excel Default Last Cell' would be from 'Actual Last Cell', the more unnecessary size of excel workbook would it be having.

Solution: Delete all rows and columns beyond the 'Actual Last Cell' in every worksheet. If there are too many worksheets and large sets of data, you can use the VBA macro mentioned on eXceLiTems.com.

Ques 01. What is the difference between ByVal and ByRef and which is default ?
Solution: ByRef: If you pass an argument by reference when calling a procedure the procedure access to the actual variable in memory. As a result the variable's value can be changed by the procedure.
ByVal: If you pass an argument by value when calling a procedure the variable's value can be changed with in the procedure only outside the actual value of the variable is retained.
ByRef is default: Passing by reference is the default in VBA. If you do not explicitly specify to pass an argument by value VBA will pass it by reference.

Ques 02. What is the meaning of Option Explicit and Option Base?
Solution: Option Explicit makes the declaration of Variables Mandatory while Option Base used at module level to declare the default lower bound for array subscripts. For eg. Option Base 1 will make the array lower bound as 1 instead of 0.

Ques 03. What are various data type and their size?
Solution:
i) The Boolean data type has only two states, True and False. These types of variables are stored as 16-bit (2 Byte) numbers, and are usually used for flags.
ii) The Byte data type is an 8-bit variable which can store value from 0 to 255.
iii) The Double data type is a 64-bit floating point number used when high accuracy is needed.
iv) The Integer data type is a 16-bit number which can range from -32768 to 32767. Integers should be used when you are working with values that can not contain fractional numbers. In case, you're working over 32767 rows use Long as data type.
v) The Long data type is a 32-bit number which can range from -2,147,483,648 to 2,147,483,647.
vi) The Single data type is a 32-bit number ranging from -3.402823e38 to -1.401298e-45 for negative values and from 1.401298e-45 to 3.402823e38 for positive values. When you need fractional numbers within this range, this is the data type to use.
vii) The String data type is usually used as a variable-length type of variable. A variable-length string can contain up to approximately 2 billion characters. Each character has a value ranging from 0 to 255 based on the ASCII character set.

Ques 04. Difference between ActiveWorkbook and ThisWorkbook.
Solution: ThisWorkbook refers to the workbook where code is being written while ActiveWorkbook refers to the workbook which is in active state with active window. In case of only one workbook open, ActiveWorkbook is same as ThisWorkbook.

Ques 05. Code to find a Last used Row in a column or Last used column of a Row.
Solution: Last Row in a column can be find using End(xlUp) and Last Column in a row can be find using End(xlToLeft). For e.g. Range("A1048576").End(xlUp).Row gives last used row of Column A.

Ques 06. Difference between ActiveX and Form Controls.
Solution:
i) Forms controls can be used on worksheets and chart sheets. Forms controls can also be placed within embedded charts in Classic Excel (though not in Excel 2007). ActiveX controls can only be used on worksheets. ActiveX controls do not work in MacExcel.
ii) The Forms controls aren’t very complicated, and they have been part of Excel for longer (they were used in Excel 5/95’s dialog sheets) than the Controls Toolbox (Excel 97), so it stands to reason that they’d be more seamlessly integrated. Being newer, the ActiveX controls have richer formatting possibilities. Both can link to cells and ranges in the worksheet.

Ques 07. What is the difference b/w Functions and Subroutines?
Solution:
i) Subroutines never return a value but functions does return values.
ii) A function could not change the values of actual arguments whereas a subroutine could change them.

Ques 08. How to debug a VBA code?
Solution: Using Breakpoints(F9), Step-by-step execution (F8), Debug.Print & Immediate Window and Watch window.

Ques 09. Draw basic Excel Object Model.
Solution: Application --> Workbooks --> Worksheets --> Range / Chart

Ques 10. What are properties, methods, events and objects?
Solution: For details click here --> http://msdn.microsoft.com/en-us/library/ms172576%28VS.80%29.aspx
All the controls in the ToolBox except the Pointer are objects in Visual Basic. These objects have associated properties, methods and events.
A property is a named attribute of a programming object. Properties define the characteristics of an object such as Size, Color etc. or sometimes the way in which it behaves.
A method is an action that can be performed on objects. For example, a cat is an object. Its properties might include long white hair, blue eyes, 3 pounds weight etc. A complete definition of cat must only encompass on its looks, but should also include a complete itemization of its activities. Therefore, a cat's methods might be move, jump, play, breath etc.
Visual Basic programs are built around events. Events are various things that can happen in a program. Let us consider a TextBox control and a few of its associated events to understand the concept of event driven programming. The TextBox control supports various events such as Change, Click, MouseMove and many more that will be listed in the Properties dropdown list in the code window for the TextBox control. We will look into a few of them as given below.
* The code entered in the Change event fires when there is a change in the contents of the TextBox
* The Click event fires when the TextBox control is clicked.
* The MouseMove event fires when the mouse is moved over the TextBox

Two tips for giving your Excel worksheets a professional look

Excel provides several underline formats to give your spreadsheets a professional look and to make them easier to read at a glance. For example, labels and values are often underlined to distinguish them from the rest of the data. To access these formats, click on the cell you want formatted and press [Ctrl]1. Click on the Font tab and then click on the drop-down arrow of the Underline combo box. This box offers four different types of line formatting. While the Single and Double format are appropriate for text labels, they are not appropriate for indicating totals and subtotals. For Totals, you should choose the Double Accounting format; for Subtotals, choose the Single Accounting format.

Another way you can make your worksheets look more professional is to remove zero values. For example, you've just copied a formula down a column, and now you have blocks of cells containing 0.00 or 0.00%. You could go back and delete the formulas from those particular cells, but an easier method would be to change the worksheet to avoid displaying or printing the zero values. To do so, follow these steps:

  1. Go to Tools | Options.
  2. Click the View tab.
  3. Under the Window Options section, clear the Zero Values check box.
  4. Click OK.
