調(diào)用api彈出打印機(jī)屬性對(duì)話框?
Author:vitoriatang

.NET?Framework封裝了很多關(guān)于打印的對(duì)話框，比如說PrintDialog,?PageSetupDialog.?
但是有的時(shí)候我們還需要關(guān)心打印機(jī)屬性對(duì)話框，那么就可以調(diào)用API來解決這個(gè)問題。有幾個(gè)API函數(shù)與之相關(guān)
PrinterProperties
DocumentProperties
OpenPrinter
ClosePrinter
逐一介紹

printerproperties
顯示打印機(jī)屬性對(duì)話框。

documentproperties
顯示打印機(jī)配置對(duì)話框。

openprinter
打開打印機(jī)

closeprinter
關(guān)閉打印機(jī)

在調(diào)用printerproperties或者documentproperties的時(shí)候，都需要先調(diào)用openprinter，并在結(jié)束后調(diào)用closeprinter。

至于打印機(jī)屬性和打印機(jī)配置有什么不同，就自己領(lǐng)會(huì)了。更為詳盡的信息可以查閱msdn

sample?codes:
1.?聲明API函數(shù)
???????[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．調(diào)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．?調(diào)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);
????????????}
