VBA Help - If no number in range, then display error.

[jammy1812]

Hi guys,
I'm working on some coding where I can search for a customer order via a UserForm and then it will attach it to Outlook and get ready to send an email, I've managed to program it so that if text or NO number is entered it will prompt the user for a number. However, when I enter an incorrect order ID (like one that doesn't exist) it will attach ALL of the sheet (with all customer data on it).

I was wondering if it is possible to display an error and say "Enter a valid order number" if the order reference does not exist.

Any thoughts?

My code is below:

Option Explicit

Private Sub cmdExit_Click()

Unload Me

End Sub

Private Sub cmdLookup_Click()

Dim Row As Integer

    If IsNumeric(txtOrderID.Text) = False Then
    MsgBox "Please enter a valid number."
    
 
Else
 


Sheets("Macro").Select

Range("A1:P1").Select

Rows(ActiveCell.Row).Select
Selection.Copy
Sheets("Export").Select
Range("A1:P1").Select
Selection.PasteSpecial
Sheets("Macro").Select
Range("K1").Activate

Do
If ActiveCell.Value = "" Then Exit Do

ActiveCell.Offset(1, 0).Activate


If ActiveCell.Value = txtOrderID.Text Then

Row = ActiveCell.Row
Rows(ActiveCell.Row).Select
Selection.Copy
Sheets("Export").Select
Range("A2").Activate
ActiveCell.PasteSpecial
ActiveCell.Offset(1, 0).Activate

Sheets("Macro").Select
Range("K" & Row).Activate

ActiveCell.Offset(1, 0).Activate
Row = ActiveCell.Row
Rows(ActiveCell.Row).Select
Selection.Copy
Sheets("Export").Select
ActiveCell.PasteSpecial

Range("A2").Activate
txtMemberID.Text = ActiveCell.Value
ActiveCell.Offset(0, 1).Activate
txtFirstName.Text = ActiveCell.Value
ActiveCell.Offset(0, 1).Activate
txtSurname.Text = ActiveCell.Value
ActiveCell.Offset(0, 9).Activate
txtOrderDate.Text = ActiveCell.Value

End If

Loop

Dim email As String
Dim subj As String
Dim msg As String
Dim Send As Integer


email = Range("E2").Value


subj = "Music By Post Ltd Invoice"



msg = "Hello " & txtFirstName & "," & vbCrLf & vbCrLf

msg = msg & "Thank you for your recent order, please find attached the summary of your order." & vbCrLf & vbCrLf

msg = msg & "Thank for your custom" & vbCrLf & vbCrLf

msg = msg & "Music By Post Ltd."



Call sendEmail(email, subj, msg, 1)

End If


End Sub

Public Sub sendEmail(email As String, subj As String, msg As String, import As Integer)

Dim Outlook As Object
Dim MailItem As Object
Dim Export As Workbook
Dim Filename As String
Dim relativePath As String


Set Outlook = CreateObject("Outlook.Application")
Set MailItem = Outlook.createItem(0)



Application.ScreenUpdating = False

ActiveSheet.Copy
    Set Export = ActiveWorkbook
    Filename = "Invoice.xls"
    On Error Resume Next
    Kill "C:\" & Filename
    On Error GoTo 0
  relativePath = ThisWorkbook.Path & "\MusicByPostInvoice" & ActiveWorkbook.Name
  ActiveWorkbook.SaveAs Filename:=relativePath
  
    
    


With MailItem

.to = email
.importance = import
.Subject = subj
.body = msg
.attachments.Add ActiveWorkbook.FullName
.Display

End With

Export.ChangeFileAccess Mode:=xlReadOnly
    Kill Export.FullName
    Export.Close SaveChanges:=False

Application.ScreenUpdating = True


Set Outlook = Nothing
Set MailItem = Nothing

Unload Me


End Sub



Private Sub TxtExit_Click()

End Sub

Private Sub UserForm_Initialize()

txtOrderID.SetFocus

End Sub
