调用api弹出打印机属性对话框

Author:vitoriatang

.NETFramework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

一、printerProperties

显示打印机属性对话框。

二、documentProperties

显示打印机配置对话框。

三、openPrinter

打开打印机

四、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

五、samplecodes:（例子代码：）

1.声明API函数

[System.Runtime.InteropServices.DllImportAttribute("winspool.drv",SetLastError=true)]
publicexternstaticintDocumentProperties(
IntPtrhWnd,//handletoparentwindow
IntPtrhPrinter,//handletoprinterobject
stringpDeviceName,//devicename
refIntPtrpDevModeOutput,//modifieddevicemode
refIntPtrpDevModeInput,//originaldevicemode
intfMode);//modeoptions[System.Runtime.InteropServices.DllImportAttribute("winspool.drv")]
publicstaticexternintPrinterProperties(
IntPtrhwnd,//handletoparentwindow
IntPtrhPrinter);//handletoprinterobject[System.Runtime.InteropServices.DllImportAttribute("winspool.drv",SetLastError=true)]
publicexternstaticintOpenPrinter(
stringpPrinterName,//printername
refIntPtrhPrinter,//handletoprinterobject
refIntPtrpDefault);//handletodefaultprinterobject.[System.Runtime.InteropServices.DllImportAttribute("winspool.drv",SetLastError=true)]
publicstaticexternintClosePrinter(
IntPtrphPrinter);//handletoprinterobject

2．调用DocumentProperties

privatevoiddocumentPropButton_Click(objectsender,EventArgse)
{
stringprinterName=_document.PrinterSettings.PrinterName;if(printerName!=null&&printerName.Length>0)
{
IntPtrpPrinter=IntPtr.Zero;
IntPtrpDevModeOutput=IntPtr.Zero;
IntPtrpDevModeInput=IntPtr.Zero;
IntPtrnullPointer=IntPtr.Zero;OpenPrinter(printerName,refpPrinter,refnullPointer);intiNeeded=DocumentProperties(this.Handle,pPrinter,printerName,refpDevModeOutput,refpDevModeInput,0);
pDevModeOutput=System.Runtime.InteropServices.Marshal.AllocHGlobal(iNeeded);
DocumentProperties(this.Handle,pPrinter,printerName,refpDevModeOutput,refpDevModeInput,DM_PROMPT);
ClosePrinter(pPrinter);
}
}

3．调用PrinterProperties

privatevoidprintPropButton_Click(objectsender,EventArgse)
{
stringprinterName=_document.PrinterSettings.PrinterName;if(printerName!=null&&printerName.Length>0)
{
IntPtrpPrinter=IntPtr.Zero;
IntPtrpDevModeOutput=IntPtr.Zero;
IntPtrpDevModeInput=IntPtr.Zero;
IntPtrnullPointer=IntPtr.Zero;OpenPrinter(printerName,refpPrinter,refnullPointer);intiNeeded=PrinterProperties(this.Handle,pPrinter);
ClosePrinter(pPrinter);
}
