呼叫api彈出印表機屬性對話方塊 
Author:vitoriatang

.NET Framework封裝了很多關於列印的對話方塊，比如說PrintDialog, PageSetupDialog. 
但是有的時候我們還需要關心印表機屬性對話方塊，那麼就可以呼叫API來解決這個問題。有幾個API函式與之相關
PrinterProperties
DocumentProperties
OpenPrinter
ClosePrinter
逐一介紹

printerproperties
顯示印表機屬性對話方塊。

documentproperties
顯示印表機配置對話方塊。

openprinter
開啟印表機

closeprinter
關閉印表機

在呼叫printerproperties或者documentproperties的時候，都需要先呼叫openprinter，並在結束後呼叫closeprinter。

至於印表機屬性和印表機配置有什麼不同，就自己領會了。更為詳盡的資訊可以查閱msdn

sample codes:
1. 宣告API函式
       [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．呼叫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． 呼叫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);
            }
