我有下面的代码,这段代码是用VB6编写的,但我无法打开窗体或检查任何引用。Excel VBA和VB6打印机
Private Sub PopulatePrinterCombo(cmbDestination As ComboBox)
Dim objPrinter As Printer 'a printer in the Printers collection object
'Add the printers to the combo box
For Each objPrinter In printers
cmbPrinter.AddItem objPrinter.DeviceName
Next
'Set current selection to the default printer
cmbDestination.Text = Printer.DeviceName
End Sub
我目前复制代码到Excel的VBA宏,问题是Dim objPrinter As Printer
代码,我不断收到一个错误信息说“用户定义类型没有定义”,我需要一个参考的VBA添加能够获得将变量声明为“打印机”的选项?
我的第二个问题是,我不完全理解行“For Each objPrinter In printers
”中的“打印机”,什么是“打印机”?有人可以向我解释这一点。
谢谢
PART 2
我现在想打印文件,我有我的代码如下:
'Initialize values
intDraftsPrinted = 0
If objDraftPaths.Count > 1 Then
Else
intSelectedDraftCount = CountSelectedDrafts
End If
'prompt user to make sure
intMsgBoxResponse = MsgBox("You selected " & intSelectedDraftCount & " part numbers. After removing duplicates" & vbNewLine & "there were " & objDraftPaths.Count & " unique draft files found." & vbNewLine & "Do you want to print these files?", vbYesNo, "TD Printer")
If intMsgBoxResponse <> vbYes Then
intSelectedDraftCount = 0 'So the following for loop will not entered
Else
intSelectedDraftCount = objDraftPaths.Count
End If
For i = 1 To intSelectedDraftCount
booSuccess = False
'open the draft file
Set objDraftDocument = OpenSolidEdgeDraft(objDraftPaths.Item(i))
If objDraftDocument Is Nothing Then
'could not open file
MsgBox "Could not open the following draft file:" & vbNewLine & _
objDraftPaths.Item(i), vbExclamation, "Solid Edge Error"
Else
'Print the draft file
For Each objSheet In objDraftDocument.Sheets
strSheetSize = DetermineSheetSize(objSheet)
If strSheetSize <> "" Then
'Determine orientation
If InStr(1, strSheetSize, "90") <> 0 Then
'Print as landscape
intOrientation = vbPRORLandscape
Else
'Print as portrait
intOrientation = vbPRORPortrait
End If
'Specify Sheet Size
Select Case Left(strSheetSize, 1)
Case "A"
intPaperSize = VBRUN.PrinterObjectConstants.vbPRPSLetter
Case "B"
intPaperSize = VBRUN.PrinterObjectConstants.vbPRPS11x17
Case "C"
intPaperSize = VBRUN.PrinterObjectConstants.vbPRPSCSheet
Case "D"
intPaperSize = VBRUN.PrinterObjectConstants.vbPRPSDSheet
Case "E"
intPaperSize = VBRUN.PrinterObjectConstants.vbPRPSESheet
Case Else
intPaperSize = VBRUN.PrinterObjectConstants.vbPRPSLetter
End Select
'Enable error handling
On Error Resume Next
'Activate the current sheet
objSheet.Activate
If Err Then
'Could not activate sheet
MsgBox "An error occurred while attempting to print: " & vbNewLine & objDraftPaths.Item(i) & vbNewLine & "The error was:" & vbNewLine & "Error Number: " & Err.Number & vbNewLine & "Error Description: " & Err.Description, vbExclamation, "Solid Edge Error"
Err.Clear
Else
'Print to the printer specified by the combo box
objDraftDocument.PrintOut cmbPrinter.Text, 1, intOrientation, intPaperSize, , , , igPrintSelected
If Err Then
'Could not print document
MsgBox "An error occurred while attempting to print: " & vbNewLine & objDraftPaths.Item(i) & vbNewLine & "The error was:" & vbNewLine & "Error Number: " & Err.Number & vbNewLine & "Error Description: " & Err.Description, vbExclamation, "Solid Edge Error"
Err.Clear
Else
booSuccess = True
End If
End If
'Disable error handling
On Error GoTo 0
End If
Next
'Close the file
objDraftDocument.Close False
intDraftsPrinted = intDraftsPrinted + 1
End If
Next i
'Dereference objects
Set objSheet = Nothing
Set objDraftDocument = Nothing
'Set objDraftPaths = Nothing
PrintSelectedDrafts = intDraftsPrinted
现在的问题是当我打线它说:intOrientation = vbPRORLandscape
在excel VBA中,它不识别“vbPRORLandscape”以及下一行“vbPRORPortrait”。有没有办法解决这个问题?
此外,我有一种感觉,VBRUN.PrinterObjectConstants.vbPRPSLetter
和其余的这些线路可能无法正常工作。它在VB6中工作。
谢谢
Google for:'application.printers excel'来看看其他人如何处理这个问题。 Excel中不存在Application.printers。没有相应的东西。大多数人都使用WinAPI来获取打印机列表。 – 2014-09-25 19:32:24
