调用api弹出打印机属性对话框 Author:vitoriatang From:Internet .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); }
