How to Add Data and Avoid Duplicates:

Sub addData()
Dim i As Long, lastrow As Long, nextBlankRow As Long
lastrow = Cells.Find(What:=”*”, _
After:=Range(“A1”), _
LookAt:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row

nextBlankRow = lastrow + 1

If Range(“E2”) = “” Then
MsgBox “You didn’t enter the first name of the customer!”
Range(“E2”).Select
Exit Sub
End If

If Range(“E3”) = “” Then
MsgBox “You didn’t enter the last name of the customer!”
Range(“E3”).Select
Exit Sub
End If

Cells(nextBlankRow, 3) = Range(“E2”)
Cells(nextBlankRow, 4) = Range(“E3”)
Cells(nextBlankRow, 5) = Range(“E4”)
Cells(nextBlankRow, 6) = Range(“E5”)
Cells(nextBlankRow, 7) = Range(“E6”)
Cells(nextBlankRow, 8) = Range(“E7”)
Cells(nextBlankRow, 9) = Range(“E8”)
‘MsgBox nextBlankRow
Dim p As Long, q As Long
p = 13
q = p + 1
Do While Cells(p, 3) <> “”
Do While Cells(q, 3) <> “”
If Cells(p, 3) = Cells(q, 3) And Cells(p, 4) = Cells(q, 4) Then
MsgBox “Duplicate Data! Will be removed from database!”
Range(Cells(q, 3), Cells(q, 9)).ClearContents
Else
q = q + 1
End If
Loop
p = p + 1
q = p + 1
Loop

End Sub

How to clear the entered data:

Sub resetData()
Range(“E2:E8”).ClearContents
End Sub

How to check or search for existing data and if the data already exists then we capture the data row and store it in Cells(4,1) or Range(“A4”). This information can help us update the record:

Sub checkExistingData()

Dim i As Long, lastrow As Long

lastrow = Cells.Find(What:=”*”, _
After:=Range(“A1”), _
LookAt:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row

If Range(“E2”) = “” Then
MsgBox “You didn’t enter the first name of the customer!”
Range(“E2”).Select
Exit Sub
End If

If Range(“E3”) = “” Then
MsgBox “You didn’t enter the last name of the customer!”
Range(“E3”).Select
Exit Sub
End If

For i = 13 To lastrow

If Cells(i, 3) = Range(“E2”) And Cells(i, 4) = Range(“E3”) Then
Range(“E4”) = Cells(i, 5)
Range(“E5”) = Cells(i, 6)
Range(“E6”) = Cells(i, 7)
Range(“E7”) = Cells(i, 8)
Range(“E8”) = Cells(i, 9)
Cells(4, 1) = i       ‘Here we capture the row of the existing data and place it in a reference cell.
Exit Sub
End If
Next i

MsgBox “Record doesn’t exist”

End Sub

How to UPDATE an existing record

Sub updateRecord()
Dim reply As String
Dim currentrow As Long

reply = InputBox(“Are you sure you wish to update the record? Type y to update”)
If reply = “y” Then
currentrow = Cells(4, 1)
Cells(currentrow, 3) = Range(“E2”)
Cells(currentrow, 4) = Range(“E3”)
Cells(currentrow, 5) = Range(“E4”)
Cells(currentrow, 6) = Range(“E5”)
Cells(currentrow, 7) = Range(“E6”)
Cells(currentrow, 8) = Range(“E7”)
Cells(currentrow, 9) = Range(“E8”)
Else
Exit Sub
Range(“E2”).Select

End If

End Sub

How to display a relevant picture or image of employee, student or customer:

Sub displayPic()
Application.ScreenUpdating = False
Dim myObj
Dim Pictur
Set myObj = ActiveSheet.DrawingObjects
For Each Pictur In myObj
If Left(Pictur.Name, 7) = “Picture” Then
Pictur.Select
Pictur.Delete
End If
Next

Dim EmployeeName As String, T As String

myDir = “C:\Users\takyar\Pictures\employees\”
EmployeeName = Range(“E2”) & Range(“E3”)
T = “.jpg”

‘Range(“F2”).Value = EmployeeName
On Error GoTo errormessage:
ActiveSheet.Shapes.AddPicture Filename:=myDir & EmployeeName & T, linktofile:=msoFalse, savewithdocument:=msoTrue, Left:=420, Top:=15, Width:=60, Height:=60

errormessage:
If Err.Number = 1004 Then
MsgBox “File does not exist.” & vbCrLf & “Check the name of the employee!”
Range(“E2”).Value = “”
Range(“E3”).Value = “”
End If

Application.ScreenUpdating = True

End Sub
