How to Find the Count of Instances or Occurrences of a Character or Substring in a String

Excel Function to Count the Number of Instances of Character or Substring in a String
In Excel we can find the Count of Instances or Occurrences of a Character or Substring in a String using the following formula :

=LEN(A1)-LEN(SUBSTITUTE(A1,";",""))

Example :

Suppose we have a String in a Cell "A1" which contains the character Semicolon  ";"

Now if we want to find how many Semicolons are there in that string , we can find using the below formula :

=LEN(A1)-LEN(SUBSTITUTE(A1,";",""))


Please observe the following examples for better understanding :

String	Count of Char/Sub String Formula	Result
ABC;DEF,@@;#@@;JKLM@@;DEF	=LEN(A2)-LEN(SUBSTITUTE(A2,";",""))	4
ABC;DEF,@@;#@@;JKLM@@;DEF	=LEN(A3)-LEN(SUBSTITUTE(A3,"@@","1"))	3
ABC;DEF,@@;#@@;JKLM@@;DEF	=LEN(A4)-LEN(SUBSTITUTE(A4,"DEF","12"))	2
ABC;DEF,@@;#@@;JKLM@@;DEF	=LEN(A5)-LEN(SUBSTITUTE(A5,"JKLM","123"))	1

Tip :
If you want to find the Instance of a Substring(Eg: ",") of length 1 character , we have to use No space ("") in above SUBSTITUTE Function.

In the Same way , If you want to find the Instance of a Substring(Eg: abc) of length 3 characters , we have to use 2 spaces("  ") or a string of length 2 characters(Eg: 12) in above SUBSTITUTE Function.

Similarly ,If you want to find the Instance of a Substring(Eg: abcd) of length 4 characters , we have to use 3 spaces("   ") or a string of length 3 characters(Eg: 123) in above SUBSTITUTE Function.

How to disable Cut,Copy,Paste and Delete Keys In Excel VBA

Excel VBA Application.Onkey to Disable Cut,Copy,Paste and Delete Keys
By using the Application.Onkey we can disable a particular Key or key combination or run a macro when you use a particular key or key combination. 

The Key argument can specify any single key combined with ALT, CTRL, or SHIFT, or any combination of these keys. Each key is represented by one or more characters, such as the  "^ {c}" for Key Combination "Ctrl+C", or "{TAB}" for the TAB key etc.

You can assigns "YourMacroName" to the key sequence CTRL+SHIFT+ENTER , as follows
Application.OnKey "^+{ENTER}", "YourMacroName"

Symbols used in Key Combinations:

Shift key = "+" (plus sign)
Ctrl key = "^" (caret)

Alt key = "%" (percent sign)

Example-I :
The following Macro is used to disable the Cut,Copy,Paste and Delete Key in Excel.
You can call this Macro in Worksheet or Workbook event to Disable or Enable Keys as per your requirement.

Sub Disable_Enable_CutCopyDel_Keys()

To Disable Copy,Cut,Past and Delete Keys
Application.EnableEvents = False

Application.OnKey "^{c}", ""              -----------------'Copy
Application.OnKey "^{x}", ""              -----------------'Cut
Application.OnKey "^{v}", ""              -----------------'Paste
Application.OnKey "{DEL}", ""

To Disable Cell Drag And Drop In Excel
Application.CellDragAndDrop = False

To Enable back the Copy,Cut,Past and Delete Keys

Application.EnableEvents = True

Application.OnKey "^{c}"              -----------------'Copy
Application.OnKey "^{x}"              -----------------'Cut
Application.OnKey "^{v}"              -----------------'Paste
Application.OnKey "{DEL}" 

To Enable back Cell Drag And Drop In Excel
Application.CellDragAndDrop = True

End Sub

Example-II :
The following Macro is used to disable the Cut,Copy options in mouse Right Click options.
You can call this Macro in Worksheet or Workbook event to Disable or Enable options as per your requirement.

Sub DisEnable_CutCopy_on_Mouse_Right_Click()

Dim Dis_Ctrl As Office.CommandBarControl

'Disable Cut Option from Mouse Right Click
     For Each Dis_Ctrl In Application.CommandBars.FindControls(ID:=21)
         Dis_Ctrl.Enabled = False
     Next Dis_Ctrl

'Disable Copy Option from Mouse Right Click
     For Each Dis_Ctrl In Application.CommandBars.FindControls(ID:=19)
          Dis_Ctrl.Enabled = False
     Next Dis_Ctrl

'Enable Cut Option from Mouse Right Click
     For Each Dis_Ctrl In Application.CommandBars.FindControls(ID:=21)
            Dis_Ctrl.Enabled = True
     Next Dis_Ctrl

'Enable Copy Option from Mouse Right Click

How to Create a Backup for Active Workbook with Current Date with Excel Macro

Excel VBA Macro to Create a Back up for Active Workbook with Current Date in Same Location.
Sub Create_Backup()
ActiveWorkbook.SaveCopyAs _
Filename:=ActiveWorkbook.Path & "\" & "BackUp" & "_" & _
Format(Date, "MM-DD-YY") & "_" & ActiveWorkbook.Name
End Sub

In the Same way we can Create a Back up for ThisWorkbook with Current Date as follows :

Sub Create_Backup()
ThisWorkbook.SaveCopyAs _
Filename:=ThisWorkbook.Path & "\" & "BackUp" & "_" & _
Format(Date, "MM-DD-YY") & "_" & ThisWorkbook.Name
End Sub

Tips :
If you want to Save the ActiveWorkbook of different format(97-2003 format) to a desired format(2007 format), use the following file format Codes.

51 = xlOpenXMLWorkbook (2007-2013, xlsx)
52 = xlOpenXMLWorkbookMacroEnabled (Macro Enabled Format in 2007-2013, xlsm)
50 = xlExcel12 (Excel Binary Format in 2007-2013 , xlsb)
56 = xlExcel8 (97-2003 Format to Excel 2007-2013, xls)

Ex:
ActiveWorkbook.SaveAs "C:\Users\YourUserName\Desktop\YourFileName", Fileformat:=52 

Note: 
It is always better to use the FileFormat Code Numbers instead of the Defined Constants in the code so that Macro will Compile OK .

Ex:
Excel 97-2003 may won't understand what is the < xlOpenXMLWorkbookMacroEnabled> Constant is.

Help :
Active Workbook means the Workbook which is Currently Active / on which we are currently working.


This Workbook means the Workbook in which we are writing the Macro code.

How to INSERT INTO Table with DEFAULT Constraint Values

SQL DEFAULT Constraint

The DEFAULT constraint is used to insert a default value into a column.

The default value will be added to all new records, if no other value is specified.

When a Field is declared as DEFAULT , it will take the default value specified , we no need to insert this value in the INSERT INTO statement.So we have to ignore or skip it.This we can do as follows :

My SQL / SQL Server / Oracle / MS Access:

CREATE TABLE Customers

(

C_Id int NOT NULL,

LastName varchar(255) NOT NULL,

FirstName varchar(255),

Address varchar(255),

City varchar(255) DEFAULT 'Hyderabad'

Gender varchar(50)

)

INSERT Statement for Table with DEFAULT Constraint values

When a Field is declared as DEFAULT , it will take the default value specified , we no need to insert this value in the INSERT INTO statement.So we have to ignore or skip it.This we can do as follows :

INSERT INTO Customers values (123,'Excel','Reddy',DEFAULT,'Male')

Here , In the INSERT INTO statement we passed DEFAULT as a value for the DEFAULT Value City.,so that it will take the Default value specified(Hyderabad) in the Table Creation.

WorkSheet Event to Zooming in and Out of a Worksheet with Double Click

WorkSheet Event BeforeDoubleClick for Zooming in and Out of a Worksheet with Double Click.
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)

'Check Current Zoom state
'Zoom to 100% if Zoom Level< 100
'Zoom to 150% if Zoom Level= 100

    If ActiveWindow.Zoom <> 100 Then
    ActiveWindow.Zoom = 100
    Else
    ActiveWindow.Zoom = 150
    End If

End Sub

WorkSheet Evet Image View :

What this Event will do Exactly :

Suppose a sheet has a Zoom Level of 60% as follows:

If you double click on any cell of a Sheet , it will Zooming the Sheet to 100% when Zoom Level is Less or Greater than it.

Again If you double click on any cell of a Sheet , it will Zooming the Sheet to 150% when Zoom Level is at 100%.

Again If you double click on any cell of a Sheet , it will Zooming back the Sheet to 100% as the Zoom Level is at 150% which Greater than 100%.

Workbook Event BeforeClose to Prevent the Closing of a Workbook when Specific Cell Value is Blank

How to Prevent the Closing of a Workbook with WorkBook Event when Specific Cell Value is Blank 

We can do this by using the WorkBook Event "BeforeClose". Just use this Code in this Event Module.

Private Sub Workbook_BeforeClose(Cancel As Boolean)

'Check to see if Cell C5 is blank
If Sheets("Sheet1").Range("B5").Value = "" Then
    
'If Blank: Cancel the Closing of WorkBook and Tell the User
    Cancel = True
    
    MsgBox "Pleas Fill Cell B5 with Value then Try to Close the Workbook", vbOKOnly, "Hi ! The Cell B5 Can Not be Blank"

'If Not Blank; Save and Close the Workbook
Else
    ActiveWorkbook.Close SaveChanges:=True
End If

End Sub

WorkBook Event Image View :

Explanation :

Suppose a Worksheet is there where the Range("B5").Value is Mandatory.

As B5 is Mandatory Cell which should not be Blank. Though if you try to Close the Workbook without filling that B5 Cell , then you get the following Message alert as per about Event.
