Question

我写了一些代码来从第一个标签上的3列（1000行数据）获取信息，以在第二个标签上填充数据（根据帐户信息地址制作一个套用信函等）。代码进入Do While，当代码继续循环时将PDF发送到队列后出现问题。只有在运行代码时才会出现错误，当单步执行代码时没有问题。

我在2003年和2007年都尝试过这种方法，但结果相似（2003年将打印3个文件，2007年我打印最多6个文件）

我还试图用

添加手动延迟

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

并在作业进入打印队列后

 Sleep 3000

我还添加了一个Do Until循环，等待打印作业降至零但没有成功。

完整的代码是：

Sub PlaceData()

Dim accountNumber As String
Dim partyID As String
Dim ClientAddress As String
Dim bRestart As Boolean
Dim totalAccounts As Long
Dim pdfjob As PDFCreator.clsPDFCreator
Dim dataPage As Worksheet
Dim letterPage As Worksheet
Dim CB As Workbook 'CB = ClientBook

Set CB = ThisWorkbook
Set dataPage = CB.Sheets("Data")
Set letterPage = CB.Sheets("Letter")


'will iterate through the account numbers down

therow = 1
'where the loop starts
totalAccounts = dataPage.Cells(Rows.Count, 1).End(xlUp).Row

Do While therow < totalAccounts
therow = therow + 1

'for the form letter

letterPage.Range("F4").FormulaR1C1 = dataPage.Range("A" & therow)
letterPage.Range("F5").FormulaR1C1 = dataPage.Range("C" & therow)
letterPage.Range("B10").FormulaR1C1 = dataPage.Range("B" & therow)


'accountnumber minus one digit for the file name
accountNumber = letterPage.Range("F4").Text
accountNumberShort = Mid(accountNumber, 1, 8)

On Error GoTo EarlyExit
Application.ScreenUpdating = False
Set pdfjob = New PDFCreator.clsPDFCreator
sPDFPath = ActiveWorkbook.Path & Application.PathSeparator

'Check if PDFCreator is already running and attempt to kill the process if so

Do
    bRestart = False
    Set pdfjob = New PDFCreator.clsPDFCreator
    If pdfjob.cStart("/NoProcessingAtStartup") = False Then
        'PDF Creator is already running.  Kill the existing process
        Shell "taskkill /f /im PDFCreator.exe", vbHide
        DoEvents
        Set pdfjob = Nothing
        bRestart = True
    End If
Loop Until bRestart = False

With pdfjob
    .cOption("UseAutosave") = 1
    .cOption("UseAutosaveDirectory") = 1
    .cOption("AutosaveDirectory") = sPDFPath
    .cOption("AutosaveFilename") = accountNumberShort
    .cOption("AutosaveFormat") = 0    ' 0 = PDF
    .cClearCache
End With

        'Delete the PDF if it already exists
        If Dir(sPDFPath & accountNumberShort) = accountNumberShort Then Kill (sPDFPath & accountNumberShort)

'Print the document to PDF

        letterPage.PrintOut copies:=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

Loop

'where the loop will end and where the issue is (I think)

'cleanups

Cleanup:
'Release objects and terminate PDFCreator
Set pdfjob = Nothing
Shell "taskkill /f /im PDFCreator.exe", vbHide
On Error GoTo 0
Application.ScreenUpdating = True
Exit Sub

EarlyExit:
'Inform user of error, and go to cleanup section
MsgBox "There was an error encountered.  PDFCreator has" & vbCrLf & _
       "has been terminated.  Please try again.", _
       vbCritical + vbOKOnly, "Error"
Resume Cleanup

Set CB = Nothing
Set dataPage = Nothing
Set letterPage = Nothing
Set pdfjob = Nothing

End Sub

我会在完成其工作后添加 PDFCreator （PDFC）的正确处理，因为不正确的处理会导致PDFC（剩余流程，资源等）的重复运行出现问题。 PDFC附带的所有代码样本至少在最低限度内实施处置，即他们至少调用clsPDFCreator.cClose()方法。

例如，检查示例文件C:\Program Files (x86)\PDFCreator\COM\VB6\Sample1\Form1.frm（如果您将PDFC安装到不同的目录中，请调整路径）。样本中的代码：

 If noStart = False Then
   PDFCreator1.cClose   ' sending cleanup&exit request to PDFCreator
   While PDFCreator1.cProgramIsRunning ' loop while PDFCreator is not found finished
     DoEvents
     Sleep 100 ' polling interval 100 ms
   Wend
 End If

 Set PDFCreator1 = Nothing
 Set pErr = Nothing
 Set opt = Nothing

其他运送的样品有时会显示一些额外的技巧，但没有错过处理部分。

来自Excel的VBA无法在循环后通过PDFCreator打印
