以前在XP環境下WEB列印成功了。今日安裝了WIN7系統,按照網上的步驟,做下來列印就是不成功;
saveas函式失敗(其中有一次運行時,存PDF成功了,后來不知道怎么回事就不行了);

圖貼的秩序比較亂,說明下:已經安裝了Ghostscript 8.63,列印機也添加了;代碼也貼出來了,存PDF時回傳SAVEas失敗!
uj5u.com熱心網友回復:
應該是權限的問題,把root目錄的權限改為everyone可寫再試試uj5u.com熱心網友回復:
或者看一下saveas的回傳值,再找一下幫助看看uj5u.com熱心網友回復:
saveas回傳-1,把root目錄的權限改為everyone可寫了;
其實發現檔案已經產生了,是0位元組;

如果生成的pdf有問題,試試把Ghostscript 8.63卸載然后重新安裝一下uj5u.com熱心網友回復:
給你篇文章參考一下05 PB 在64位作業系統下,如何讓PDF另存功能好用
首先我要宣告的是,這個方法在PB9+WIN7 64位下不好用。只適用于 PB12, 12.5。PB9的仍然得安裝GhostScript 7.05,不能高于這個版本。
1,安裝GhostScirpt 8.71
注意版本,高過這個版本就有時不好用。。
2,安裝64位的PS列印機驅動程式,將列印機名稱設定為 "Sybase DataWindow PS"
注意 列印機驅動可以選用HP的PS列印機。
別看我只寫了這2條,我試驗了1個星期!
如果自己下載不到,可以到下面這個地址下載去:(注意:要CSDN分)
GhostScirpt 8.71 & HP ps列印驅動
在PB的CS環境中,saveAS 是一般是沒有問題的,如果在DW.NET的WEB條件下,呼叫SAVEas 是不好用的,主要原因是BS條件下,IIS對列印機沒有操作權限,也因為權限問題,無法新建檔案。經過查詢DW.NET的幫助檔案,發現按照下面文章所述,是可以進行dw.net的SAVEAS的。
在64位WIN下,DW.net save as PDF時,會提示-1的錯誤,保存不成功。其原因是:本地系統賬號沒有獲得列印機權限。那么如何修改列印機權限呢?請按下面步驟:
(1) 當前用戶在WEBSERVER的列印機需要先安裝好。
(2) 在“開始”、“運行”中,運行注冊表編輯器:regedit。
(3) 選擇HKEY_USERS\.DEFAULT\Software\Microsoft\Windows NT\CurrentVersion, 將之匯出為一個注冊表備份檔案,這個備份檔案是以防萬一改錯了恢復用的。。
(4) 選擇HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion,
a) 選擇Devices子鍵,匯出檔案,檔案名為device.reg
b) 選擇PrinterPorts子鍵,匯出檔案,檔案名為Printports.reg
c) 選擇Windows子鍵,匯出檔案,檔案名為Windows.reg
(5) 用記事本或者其他的文本編輯器,
a) 編輯device.reg檔案,將HKEY_CURRENT_USER替換成HKEY_USERS\.DEFAULT
b) 編輯Printports.reg檔案,將HKEY_CURRENT_USER替換成HKEY_USERS\.DEFAULT
c) 編輯Windows.reg檔案,將HKEY_CURRENT_USER替換成HKEY_USERS\.DEFAULT
(6) 保存著3個檔案后,雙擊這3個檔案,將注冊表內容匯入到系統中。
(7) 重啟IIS和WEBSITE使配置生效。
最后補充:
有一天,發現2件事,一個好事一個壞事:
(1)這種情況下生成的PDF是彩色的,而以前32位下生成的是黑白的。這個是好事。
(2)這種情況下生成的PDF是不帶圖形的,也就是說,你在DW中添加了諸如picture這樣的控制元件,那么對不起了,PDF里不顯示。BITMAP函式的計算列顯示的圖形也會不見了。
經過網友“上海-盛永翔”提醒:絕對路徑是好用的,于是測驗,結論如下:
最后確認:用這個HP的驅動,的確能使64位下能正確生成PDF
但是:
在.NET網頁中,用./images/aa.jpg可以顯示圖形,但是在列印的PDF中不可以顯示圖形
在.NET網頁中,用c:\wwwroot\webpage\images\aa.jpg不可以顯示,但是在列印的PDF中可以顯示圖形
所以,需要顯示時候用./images/**.jpg表示,在生成PDF是必須用c:\wwwroot\webpage\images\**.jpg的路徑來表示圖形
看你自己怎么發揮了,我是在另存為PDF時候,去MODIFY picture控制元件的filename屬性。
====以下英文檔案可以不看,大部分是廢話,按上面的方法設定列印機權限部分即可。========
If your DataWindow .NET application specifies a path for dynamically generated files, make sure that the ASP.NET account (or, for Windows 2003 server, the IIS_WPG user group) has write permission to the directories. You need to do this if your application uses graphs in Web DataWindows or saves the JavaScript, XML, XSLT, and CSS files generated for XML or XHTML Web DataWindows into separate directories.
The Web server must be configured so that the ASP.NET worker process has access to system settings and the SYSTEM account has access to printers. Implementing server-side printing requires changing the default permissions on the server.
By default, the .NET Framework runs with the permissions of the local “machine” account. In order to print using IIS, the .NET Framework must run with the permissions of the local “SYSTEM” account. The procedures for configuring the .NET Framework for IIS 5.x and 6.x are different.
To configure the .NET Framework to run with local SYSTEM settings with
IIS 6.x:
1 In the Windows Start>Run box, type InetMgr.
2 In the IIS Manager, expand local computer and select Application Pools.
3 Right-click Application Pools and select Properties.
4 Click the Identity tab, select Local System from the Predefined list box,
and click OK.
5 Click Yes in the pop-up warning message window that displays.
6 Right-click local computer and select All Tasks>Restart IIS to restart IIS.
Exposing printer settings to the SYSTEM account
When a printer is installed on a computer, its settings are stored in the HKEY_CURRENT_USER registry key. IIS runs under the context of the local SYSTEM account. It has access to the HKEY_USERS registry key, but not to the HKEY_CURRENT_USERS subkey, which is only available to a user logged on to the computer.
By default, no printers are defined in the HKEY_USERS key. You can add them by exporting three keys from the HKEY_CURRENT_USERS key and importing them to the HKEY_USERS key.
注意:
Incorrectly editing the registry might severely damage your system. Make sure you back up valued data before making changes to the registry.
先備份注冊表.
To make printer settings available to the SYSTEM account:
1 Check that the current user on the Web server has the required printer(s) installed.
2 To launch the Registry Editor, type regedit in the Start>Run dialog box and click OK.
3 Select the HKEY_USERS\.DEFAULT\Software\Microsoft\Windows NT\CurrentVersion key and export the registry key from the File or Registry menu.
4 Specify a name and location in the Export Registry File dialog box and
click Save. This file provides a backup if you need to restore the registry.
5 In the HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion key, select the Devices subkey and export the registry key.
6 Specify the name devices.reg and a temporary location in the Export Registry File dialog box and click Save.
7 Repeat steps 5 and 6 for the PrinterPorts and Windows subkeys, naming the files printerports.reg and windows.reg.
8 Open devices.reg in Notepad (do not use TextPad or another editor), replace the string HKEY_CURRENT_USER with the string HKEY_USERS\.DEFAULT (note that there is a dot before DEFAULT), and save the file.
9 Repeat step 8 for printerports.reg and windows.reg.
10 Double-click each of the edited files to import them into the registry.
11 Restart IIS so that the configuration changes take effect.
To restart IIS:
1 In the Windows Start>Run box, type InetMgr.
2 In the IIS Manager, right-click the local computer and select All Tasks>Restart IIS.
3 In the Start/Stop/Reboot dialog box, select Restart Internet Services on ComputerName, where ComputerName is the local computer.
After restarting IIS, you need to restart the Web site.
DW保存PDF(saveas)必須滿足如下要求:
(1)Configure the .NET Framework to run under the SYSTEM account and expose printer settings to the SYSTEM account as described in “Serverside printing” on page 208.
(2)Make sure that the Sybase DataWindow PS profile is exposed to the SYSTEM account as described next.
(3)Create a folder on the server in which to save the PDF files and set its permissions so that the ASP.NET application process has write access to it.
On Windows 2003 Server, a default Group Policy disallows installation of printers that use kernel-mode drivers, and as a result the driver used by the Sybase DataWindow PS profile is not installed. Kernel-mode drivers have access to system-wide memory, and poorly written drivers can cause system failures. To allow installation of kernel-mode drivers, follow these steps:
Select Run from the Windows Start menu.
In the Open box, type gpedit.msc and click OK.
In the Group Policy console, expand Computer Configuration, Administrative Templates, and Printers.
Disable “Disallow Installation of Printers Using Kernel-Mode Drivers.”
