EXCEL VBA：创建一个简单的循环来重复每一行的进程

Question

I know it might seem to be a very simple question but I tried different methods to create a loop that would do what I'm looking for: Basically I have an excel sheet with 4 columns (unknown number of rows) in which I want to enter data. This data is then mirrored to a second sheet that contains the "printing design" that I use to create multiple PDF files. Problem is: I tried for 4 days now to create a loop and have not achieved anything!

If you could help me, this is the data entry: SCREENSHOT

Public Sub InputData()

Dim strCap As String
strCap = Sheets("INPUT").Cells(4, 3).Value
Label1.Caption = strCap

Dim strCap2 As String
strCap2 = Sheets("INPUT").Cells(4, 5).Value
Label2.Caption = strCap2

If Sheets("INPUT").Cells(4, 4) = "OE" Then
    Image1.Picture = LoadPicture(ActiveWorkbook.Path & "\OE_Logo.jpg")
Else
    Image1.Picture = LoadPicture(ActiveWorkbook.Path & "\SF_Logo.jpg")
End If

If Sheets("INPUT").Cells(4, 6) = "OE" Then
    Image2.Picture = LoadPicture(ActiveWorkbook.Path & "\OE_Logo.jpg")
Else
    Image2.Picture = LoadPicture(ActiveWorkbook.Path & "\SF_Logo.jpg")
End If

Application.Calculate

Call PrintPDF

End Sub


Sub PrintPDF()
Dim pdfjob As Object
Dim sPDFName As String
Dim sPDFPath As String
 '/// Change the output file name here! ///
sPDFName = "Affidavit" & " " & Sheets("INPUT").Cells(4, 3) & "_" & Sheets    ("INPUT").Cells(4, 5) & ".pdf"
sPDFPath = ActiveWorkbook.Path & Application.PathSeparator
 'Check if worksheet is empty and exit if so
If IsEmpty(ActiveSheet.UsedRange) Then Exit Sub
Set pdfjob = CreateObject("PDFCreator.clsPDFCreator")
With pdfjob
    If .cStart("/NoProcessingAtStartup") = False Then
        MsgBox "Can't initialize PDFCreator.", vbCritical + _
        vbOKOnly, "PrtPDFCreator"
        Exit Sub
    End If
    .cOption("UseAutosave") = 1
    .cOption("UseAutosaveDirectory") = 1
    .cOption("AutosaveDirectory") = sPDFPath
    .cOption("AutosaveFilename") = sPDFName
    .cOption("AutosaveFormat") = 0 ' 0 = PDF
    .cClearCache
End With
 'Print the document to PDF

Sheets("AFFIDAVIT CREATOR").PrintOut Copies:=1, From:=1, To:=1, ActivePrinter:="PDFCreator"
 'Wait until the print job has entered the print queue
Do Until pdfjob.cCountOfPrintjobs = 1
    DoEvents
Loop
pdfjob.cPrinterStop = False
 'Wait until PDF creator is finished then release the objects
Do Until pdfjob.cCountOfPrintjobs = 0
    DoEvents
Loop
pdfjob.cClose
Set pdfjob = Nothing
End Sub

I actually want to create One SINGLE PDF file for each row, so do this for row 4, 5, 6 etc. till VBA finds an empty row.

Any help would be highly appreciated, thanks in advance for all the help I was able to find on Stackoverflow and hopefully help to come!

Thanks,

Yannick

In general, a good way to create a loop in VBA involves these steps:

1. Define the range of cells over which you want to loop
2. Assign the range to a variable (declared with Dim myRange as Range )
3. Loop over the (cells, rows) of the range with a loop like this:

Dim r as Range, myRange as Range
    Set myRange = Range(Sheet("INPUT").cells(4,4), Sheet("INPUT").cells(4,4).end(xlDown))
    For Each r in myRange.Cells
      turnRowIntoPdf r
    Next

This will define myRange to be the range that starts at cell (4,4) - ie D4 - and goes as far down as there are entries. It will then loop over each of these cells in turn (D4, D5, D6, ...) and call a Sub turnRowIntoPdf with parameter r (which will be each of these cells in turn). You can then write a sub that takes this parameter as input, and creates the pdf.

Think you can manage it from there?
