示例

下面的代码示例在所选内容发生变化时，使用 PrinterName 属性将已安装的打印机填充到 comboInstalledPrinters 组合框中并设置要进行打印的打印机。在窗体初始化过程中调用 PopulateInstalledPrintersCombo 例程。该示例要求名为 printDoc 的 PrintDocument 变量和特定的组合框都已存在。

Private Sub PopulateInstalledPrintersCombo()
    ' Add list of installed printers found to the combo box.
    ' The pkInstalledPrinters string will be used to provide the display string.
    Dim i as Integer
    Dim pkInstalledPrinters As String

    For i = 0 to PrinterSettings.InstalledPrinters.Count - 1
        pkInstalledPrinters = PrinterSettings.InstalledPrinters.Item(i)
        comboInstalledPrinters.Items.Add(pkInstalledPrinters)
    Next
End Sub

    If comboInstalledPrinters.SelectedIndex <> -1 Then
        ' The combo box's Text property returns the selected item's text, which is the printer name.
        printDoc.PrinterSettings.PrinterName = comboInstalledPrinters.Text
