Form Data to Particular Cells - vba

Question

In Excel sheet2 i have Columns A & D for Name, B & E Start Date and column C & F is End Date and a Form with ComboBox (loaded with names) and two Textboxes.
I want when I click submit button it will search the columns for a name that matches the ComboBox value and then write the values of the two TextBoxes into the right adjacent two EMPTY cells
Private Sub CommandButton4_Click()
Dim irow As Long
Dim ws As Worksheet
Set ws = Worksheets("Sheet2")
With ws
.Cells(.Rows.Count, "A").End(xlUp).Offset(1, 0).Value = Me.Combo.Value
.Cells(.Rows.Count, "B").End(xlUp).Offset(1, 0).Value = Me.sttdate.value
.Cells(Rows.Count, "C").End(xlUp).Offset(1, 0).Value = Me.enddate.Value
End With
With Me
.Combo.Value = ""
.startdate.Value = ""
.enddate.Value = ""
End With
End Sub
This code is adding value of all form into Columns A B & C

Answer 1

This should do the trick. I added some checks based on what you wrote in your explanation in case it helps.
Private Sub CommandButton4_Click()
Dim irow As Long
Dim ws As Worksheet
Set ws = Worksheets("Sheet2")
With ws
irow = .Range("A" & .Rows.Count).End(xlup).Row
Dim rFound as Range
Set rFound = .Range("A1:A" & iRow).Find(Me.Combo.Value, lookat:=xlWhole)
If not rFound is Nothing Then
If IsEmpty(rFound.Offset(,1)) and IsEmtpy(rFound.Offset(,2)) Then
rFound.Offset(,1) = Me.sttdate.value
rFound.Offset(,2) = Me.enddate.value
With Me
.Combo.Value = ""
.startdate.Value = ""
.enddate.Value = ""
End With
Else
Msgbox "Name already has values"
End If
Else
Msgbox "Name not Found"
End If
End Sub

This should work just fine :
Private Sub CommandButton4_Click()
Dim irow As Long, _
wS As Worksheet, _
NextRow As Long, _
cF As Range
Set wS = Worksheets("Sheet2")
With wS
With .Range("A:A")
'First, define properly the Find method
Set cF = .Find(What:=Me.Combo.Value, _
After:=.Cells(1, 1), _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByRows, _
SearchDirection:=xlNext, _
MatchCase:=False, _
SearchFormat:=False)
End With
'If there is a result, keep looking with FindNext method
If Not cF Is Nothing Then
If cF.Offset(0, 1) <> vbNullString Then
Set cF = cF.End(xlToRight).Offset(0, 1)
cF.Value = Me.sttdate.Value
cF.Offset(0, 1).Value = Me.EndDate.Value
Else
.Cells(cF.Row, "B").Value = Me.sttdate.Value
.Cells(cF.Row, "C").Value = Me.EndDate.Value
End If
Else
NextRow = .Cells(.Rows.Count, "A").End(xlUp).Offset(1, 0).Row
.Cells(NextRow, "A").Value = Me.Combo.Value
.Cells(NextRow, "B").Value = Me.sttdate.Value
.Cells(NextRow, "C").Value = Me.EndDate.Value
End If
End With
With Me
.Combo.Value = ""
.StartDate.Value = ""
.EndDate.Value = ""
End With
End Sub
