Using # In If Condition

# is used only for numeric values in VBA


Option Explicit
Dim mydata, tempval, i

Sub getData()
mydata = Application.InputBox("Enter Data", "Data", Type:=2)
For i = 1 To Len(mydata)
    If Mid(mydata, i, 1) Like "#" Then
        tempval = tempval & Mid(mydata, i, 1)
    End If
Next i
MsgBox tempval
tempval = vbNullString
End Sub

Finding files name from folders/Subfolders

first of all you will add FSO References

Step for Add:- Tools-Reference-Microsoft Scripting Runtime
and try below code

Sub File_name()

Dim fso As FileSystemObject
Dim fl As File
Dim fldr As Folder
Dim wb As Workbook
Set wb = ThisWorkbook
Set fso = New FileSystemObject
Application.FileDialog(msoFileDialogFolderPicker).Title = "Choose Folder"
Application.FileDialog(msoFileDialogFolderPicker).Show
Dim fldpath As String
fldpath = Application.FileDialog(msoFileDialogFolderPicker).SelectedItems(1)
& "\"
Set fldr = fso.GetFolder(fldpath)
i = 2
For Each fl In fldr.Files
Sheet3.Cells(i, "D").Value = fl.Name
i = i + 1
Next fl
End Sub

Form Control vs. ActiveX Control in MS Excel

Difference	ActiveX Controls	Excel Controls
Excel versions	97, 2000	5, 95, 97, 2000
Which toolbar?	Control Toolbox	Forms
Controls available	CheckBox, TextBox, CommandButton, OptionButton, ListBox, ComboBox, ToggleButton, SpinButton, ScrollBar, Label, Image	Label, GroupBox, Button, CheckBox, OptionButton, ListBox, ComboBox, ScrollBar, Spinner
Macro code storage	In the code module for the Sheet	In any standard VBA module
Macro name	Corresponds to the control name (e.g., CommandButton1_Click)	Any name you specify.
Correspond to...	UserForm controls	Dialog Sheet controls
Customization	Extensive, using the Properties box	Minimal
Respond to events	Yes	Click or Change events only

Example of Select Case in VBA

Dim rng As Range, totalsalary As Long

Sub calculatesalary()
Set rng = Application.InputBox("Select Range", "salary", Type:=8)
For Each cell In rng
        Select Case cell.Value
        Case Is <= 900
         totalsalary = cell.Value + (cell.Value * 0.1)
        Case 901 To 1000
         totalsalary = cell.Value + (cell.Value * 0.125)
        Case Is > 1000
        totalsalary = cell.Value + (cell.Value * 0.15)
        End Select
        cell.Offset(, 1) = totalsalary
Next
End Sub

Using Enumeration In VBA

VBA code to develop a function to calculate salary with allowance



Public Enum commission
grade1 = 100
grade2 = 125
grade3 = 150
End Enum

Function Calculatesalary(ByVal rng As Range) As Long
Dim salary, totalsalary As Long, myrng As Range

Set myrng = rng

salary = CLng(myrng.Value)

Select Case (salary <= 900)
Case True

    totalsalary = salary + salary * ((commission.grade1) / 1000)
 
Case Else
    Select Case (900 < salary <= 1000)
    Case True
    totalsalary = salary + salary * ((commission.grade2) / 1000)
    Case Else
        Select Case (1000 < salary)
        Case True
            totalsalary = salary + salary * ((commission.grade3) / 1000)
        End Select
    End Select

End Select

Calculatesalary = totalsalary


totalsalary = 0
End Function

Count of Vowels In A String USING VBA

Option Explicit
Dim i As Integer, j As Integer
Dim myval As String
Sub countofVowels()
myval = Application.InputBox("Enter a word", "Word", Type:=2)

For i = 1 To Len(myval)
If LCase(Mid(myval, i, 1)) Like "[a,e,i,o,u]" Then

For example  if you want to insert a row after every unique region here is code

Option Explicit
Dim mycoll As Collection, strrow As String, finalstrrow As String
Dim myrng As Range, rowcount As Long, cell, i As Integer
Sub insertRowafterUnique()
rowcount = ThisWorkbook.Sheets(1).Range("A1").End(xlDown).Row
Set mycoll = New Collection
Set myrng = ThisWorkbook.Sheets(1).Range("A2:A" & rowcount)
strrow = vbNullString
On Error Resume Next
    For Each cell In myrng
        mycoll.Add cell, CStr(cell)

    Next
 
    For i = 2 To rowcount
            If ThisWorkbook.Sheets(1).Range("A" & i) <> ThisWorkbook.Sheets(1).Range("A" & (i + 1)) Then
                strrow = strrow & (i + 1) & ":" & (i + 1) & ","
             
 
 
            End If
    Next
    finalstrrow = Left(strrow, Len(strrow) - 1)
    ThisWorkbook.Sheets(1).Range(finalstrrow).EntireRow.Insert
End Sub

VBA Automation for MS Excel File

In Master Sheet there are three cells in attached sheet G1,G2 & J2.  When I will run macro it should check that whether values are entered in these cells.  If any one of cells are blank, cell should be RED and give message that values are not entered. and then it should ask Do you want to enter data now, if yes input box for entering value.


Option Explicit
Dim birth As Range, PANNo As Range, empName As Range, userInput



Sub validateData()
Application.ScreenUpdating = False
Set birth = [G2]
Set PANNo = [J2]
Set empName = [G1]
If IsEmpty(empName) Then
    [empName].Interior.ColorIndex = 3
    [empName].Interior.Pattern = xlSolid
    If MsgBox("Employee Name is empty;Please enter now", vbYesNo) = vbYes Then
        userInput = Application.InputBox("Please Enter Employee name", Type:=2)
        If Len(userInput) > 0 Then
            [empName].Value = userInput
            [empName].Interior.ColorIndex = 2
        End If
    End If
End If
If IsEmpty(birth) Then
    [birth].Interior.ColorIndex = 3
    [birth].Interior.Pattern = xlSolid
    If MsgBox("Date of Birth is empty; Please enter now", vbYesNo) = vbYes Then
    userInput = vbNullString
        userInput = Application.InputBox("Enter DOB", "DOB in mm/dd/yyyy format", Default:=Format(Date, "mm/dd/yyyy"), Type:=2)
        If IsDate(userInput) Then
            [birth].Value = userInput
            [birth].Interior.ColorIndex = 2
        End If
    End If

 
End If
If IsEmpty(PANNo) Then

    [PANNo].Interior.ColorIndex = 3
    [PANNo].Interior.Pattern = xlSolid
    If MsgBox("PAN No. is empty;Please enter now", vbYesNo) = vbYes Then
        userInput = vbNullString
        userInput = Application.InputBox("Enter PAN No.", "PAN No.", Type:=2)
        If Len(userInput) = 10 Then
            [PANNo].Value = userInput
            [PANNo].Interior.ColorIndex = 2
        End If
    End If
End If
