调用API弹出打印机属性对话框

Posted on 2005-09-09 12:13 Vitoria 阅读(...) 评论(...) 编辑 收藏
.NET Framework封装了很多关于打印的对话框,比如说PrintDialog, PageSetupDialog.

但是有的时候我们还需要关心打印机属性对话框,那么就可以调用API来解决这个问题。有几个API函数与之相关
PrinterProperties
DocumentProperties
OpenPrinter
ClosePrinter
逐一介绍

PrinterProperties
显示打印机属性对话框。

DocumentProperties
显示打印机配置对话框。

OpenPrinter
打开打印机

ClosePrinter
关闭打印机

在调用PrinterProperties或者DocumentProperties的时候,都需要先调用OpenPrinter,并在结束后调用ClosePrinter

至于打印机属性和打印机配置有什么不同,就自己领会了。更为详尽的信息可以查阅msdn

Sample codes:
1. 声明API函数
       [System.Runtime.InteropServices.DllImportAttribute("winspool.drv", SetLastError = true)]
       public extern static int DocumentProperties(
            IntPtr hWnd,              // handle to parent window 
            IntPtr hPrinter,           // handle to printer object
            string pDeviceName,   // device name
            ref IntPtr pDevModeOutput, // modified device mode
            ref IntPtr pDevModeInput,   // original device mode
            int fMode);                 // mode options 

        [System.Runtime.InteropServices.DllImportAttribute("winspool.drv")]
        public static extern int PrinterProperties(
            IntPtr hwnd,  // handle to parent window
            IntPtr hPrinter); // handle to printer object

         [System.Runtime.InteropServices.DllImportAttribute("winspool.drv", SetLastError = true)]
        public extern static int OpenPrinter(
            string pPrinterName,   // printer name
            ref IntPtr hPrinter,      // handle to printer object
            ref IntPtr pDefault);    // handle to default printer object. 

        [System.Runtime.InteropServices.DllImportAttribute("winspool.drv", SetLastError = true)]
        public static extern int ClosePrinter(
            IntPtr phPrinter); // handle to printer object

2.调用DocumentProperties
private void documentPropButton_Click(object sender, EventArgs e)
        {
            string printerName = _document.PrinterSettings.PrinterName; 

            if (printerName != null && printerName.Length > 0)
            {
                IntPtr pPrinter = IntPtr.Zero;
                IntPtr pDevModeOutput = IntPtr.Zero;
                IntPtr pDevModeInput = IntPtr.Zero;
                IntPtr nullPointer = IntPtr.Zero;

                 OpenPrinter(printerName, ref pPrinter, ref nullPointer); 

                int iNeeded = DocumentProperties(this.Handle, pPrinter, printerName, ref pDevModeOutput, ref pDevModeInput, 0);
                pDevModeOutput = System.Runtime.InteropServices.Marshal.AllocHGlobal(iNeeded);
                DocumentProperties(this.Handle, pPrinter, printerName, ref pDevModeOutput, ref pDevModeInput, DM_PROMPT);
                ClosePrinter(pPrinter);
            }
        }

 

3 调用PrinterProperties
private void printPropButton_Click(object sender, EventArgs e)
        {
            string printerName = _document.PrinterSettings.PrinterName; 

            if (printerName != null && printerName.Length > 0)
            {
                IntPtr pPrinter = IntPtr.Zero;
                IntPtr pDevModeOutput = IntPtr.Zero;
                IntPtr pDevModeInput = IntPtr.Zero;
                IntPtr nullPointer = IntPtr.Zero;

                 OpenPrinter(printerName, ref pPrinter, ref nullPointer); 

                int iNeeded = PrinterProperties(this.Handle, pPrinter);
                ClosePrinter(pPrinter);
            }
        }
