Dim TempWb As Workbook

Set Sourcewb = ActiveWorkbook

If Dir(Environ("commonprogramfiles") & "\Microsoft Shared\OFFICE"
_
& Format(Val(Application.Version), "00") & "\EXP_PDF.DLL") <
"" Then

Sourcewb.Sheets(Array("E-Mail1")).Copy
Set TempWb = ActiveWorkbook


FilenameStr = Application.DefaultFilePath & "\" & "Part of " &
Sourcewb.Name & " " & Format(Now, "dd-mmm-yy h-mm") & ".pdf"

ActiveSheet.ExportAsFixedFormat _
Type:=xlTypePDF, _
Filename:=FilenameStr, _

'Close the new workbook you create file without saving
TempWb.Close False


Set OutApp = CreateObject("Outlook.Application")
OutApp.Session.Logon
Set OutMail = OutApp.CreateItem(0)


For Each cell In ThisWorkbook.Sheets("E-Mail1").Range("BV1:BV2")
strbody = strbody & cell.Value & vbNewLine
Next

For Each cell In ThisWorkbook.Sheets("E-Mail1") _
.Columns("BY").Cells.SpecialCells(xlCellTypeConsta nts)
If cell.Value Like "?*@?*.?*" Then
strto = strto & cell.Value & ";"
End If
Next
strto = Left(strto, Len(strto) - 1)
