exporting a certain worksheet from a workbook to pdf - vba

Question

i am an amateur programmer learning how to program using vba
without further a due, my question is :
i have created a listbox (listbox1) where i've listed all my sheets(ws) name in a specific workbook.
i've also created another listbox(listbox2) where when i select some sheets name on the listbox1, they will be transfer to listbox2.
my main objective is that by choosing one or more sheets listed in the listbox2, and by clicking a button, i'll manage to save all the selected sheets in one pdf file.
here is the code for the button used to export the file in pdf that i've written but i've only managed to export them not in one pdf file but in numerous amount of pdf file.
Dim NomTableau() As String
For Each WkbkName In application.Workbooks()
If WkbkName.Name = choix_poteau.Value & "_" & section & "_" & projet & ".xlsx" Then
WkbkName.Activate
GoTo lois
End If
Next
Set wbk = Workbooks.Open(add1 & "\" & Me.projet.Value & "\" & Me.section.Value & "\poteaux\" & Me.choix_poteau.Value & "_" & Me.section & "_" & Me.projet & ".xlsx")
lois:
For i = 0 To ListBox2.ListCount - 1
While ListBox2.List(i) <> ""
Dim ws As Worksheet
For Each ws In Worksheets
If ws.Name = ListBox2.List(i) Then
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"C:\Export\Resultats__" & ListBox2.List(i - counter) & ".pdf", Quality:=xlQualityStandard, _
IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
True
End If
Next
Wend
Next i
End Sub
thanks alot, really appreciate your help

Answer 1

Instead of exporting each sheet individually, select them all first and then call the ExportAsFixedFormat method.
Here is my test code, which worked as expected:
Option Explicit
Private Sub TestPDF()
Dim i As Integer
Dim arrSheets() As String
Dim strSheets As String
'Get our sheet names
For i = 1 To 3
strSheets = Worksheets(i).Name & "," & strSheets
Next
'Trim the trailing comma
strSheets = Left(strSheets, Len(strSheets) - 1)
arrSheets = Split(strSheets, ",")
ThisWorkbook.Sheets(arrSheets).Select
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"C:\Users\qzbcjs\Documents\Useful Workbooks\test.pdf", Quality:=xlQualityStandard, _
IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
True
End Sub
I declared an array of strings, populated a string variable with the comma-delimited names of the worksheets (in my case I just wanted the first through third sheets), split that comma-delimited string into an array and used the array to select all of the desired sheets and only called the ExportAsFixedFormat method once.
Adapting this method to your code, beginning as the lois part would look something like this:
lois:
Dim ws As Worksheet
Dim arrSheets() As String
Dim strWs As String
For i = 0 To ListBox2.ListCount - 1
While ListBox2.List(i) <> ""
For Each ws In Worksheets
If ws.Name = ListBox2.List(i) Then
strWs = ws.Name & "," & strWs
End If
Next
Wend
Next i
strWs = Left(strWs, Len(strWs) - 1)
arrSheets = Split(strWs, ",")
ThisWorkbook.Sheets(arrSheets).Select
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"C:\Export\Resultats__" & ListBox2.List(i - counter) & ".pdf", Quality:=xlQualityStandard, _
IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
True
