Delphi与Word之间的融合技术
(yzhshi@263.net)​
一、VBA代码含义
Microsoft Word是一个集成化环境,是美国微软公司的字处理系统,但是它决不仅仅是一个字处
理系统,它集成了Microsoft Visual Basic,可以通过编程来实现对Word功能的扩展。
Microsoft Visual Basic在word中的代码即Word的宏,通过编写Word宏,可实现一些文档处理的
自动化,如实现文档的自动备份、存盘等,可扩展Word文档的功能,因此,能够充分利用Word的
特性,甚至使Word成为自己软件的一部分。
Word的宏既有有利的一部分,因为它能够帮助我们实现文档的自动化,但是Word的宏也不是纯粹
的有利,有时它可能危害我们的文档、计算机系统甚至网络,从最开始的Taiwan NO1宏病毒到现
在的Melissa宏病毒,从最开始的简单的提示,耗尽系统资源到现在的乱发电子邮件,将个人的
信息发送到网络上,甚至向硬盘的Autoexec.bat(自动批处理文件)中添加Deltree C: -y,破坏
整个Windows系统。

二、Word中内嵌的Com技术
可以说Word是对Com技术支持最好的软件,这样说似乎是太极端了一点,但是Word提供的强大的编
程接口技术却能够是我们通过程序控制Word的任何一部分。无论是文件的打开、存盘、打印还是文
档中表格的自动绘制。
通过编程软件,可以灵活的操纵word,这里只以Borland Delphi为例,进行详细描述:
1、 在Delphi中调用Word软件/文件的方法
在Word中调用Word软件,归纳起来有三种方法:
。通过Delphi的控件TOleContainer 将Word嵌入
a.使用Delphi提供的Servers控件调用Word,使用Word的属性
b.通过真正的Com技术,将Office软件目录中文件MSWORD9.OLB中的类库全部导入Delphi中,
利用Com技术编程
c.使用CreateOleObject将启动Word,然后以Ole方式对Word进行控制。

2、 对几种方法的难易程度的判别

a.通过Delphi的控件TOleContainer 将Word嵌入

这是最简单的Ole嵌入,能够直接将Word文档调用,只需要使用ToleContainer.Run就可以将Word文
档直接启动。且这样启动的Word文档与Delphi程序是一个整体(从界面上看),但是它存在不可克
服的缺点,即不能通过Delphi控制Word文档,也就不能实现将灵活操纵Word的目的。

b.使用Delphi提供的Servers控件调用Word,使用Word的属性
使用Delphi的Servers控件来操纵Word,在编程时Delphi能够实现代码提示,总体上看能够较好的实
现Delphi对Word的控制,但是还有一些Word的功能不能在Delphi中调用(比如自己编写的VBA宏代码)。
且实现功能时本来在VBA代码中可选则参数在Delphi调用的时候必须添加,否则,连编译都不能通过。
本方式启动的Word与Delphi程序分属两个窗体。
此办法仅能作为一个参考。

c.通过真正的Com技术,将Office软件目录中文件MSWORD9.OLB中的类库全部导入Delphi中,
利用Com技术编程
利用真正的Com技术,将MsWord9.OLD文件类库导入,然后利用Com技术进行使用。
整体上类似使用Delphi的Servers控件,稍微比Servers控件麻烦,优缺点与Servers控件相同。

d.使用CreateOleObject将启动Word,然后以Ole方式对Word进行控制。
本办法是使用以CreateOleObjects方式调用Word,实际上还是Ole,但是这种方式能够真正做到完全
控制Word文件,能够使用Word的所有属性,包括自己编写的VBA宏代码。
与Servers控件和com技术相比,本方法能够真正地使用Word的各种属性,和在VBA中编写自己的代码
基本一样,可以缺省的代码也不需要使用。
本方式启动的Word与Delphi程序分属两个窗体。
缺点是使用本方法没有Delphi代码提示,所有异常处理均需要自己编写,可能编写时探索性知识比较多。

三、Word宏编辑器
Word能够真正地进行VBA代码的编辑,可以编写窗体、函数。
进入Word宏编辑器的方法:工具->宏->Visual Basic编辑器,可进入Visual Basic编辑器界面。
Word的Visual Basic编辑器界面和真正的Visual Basic编辑器基本相同,在此不再向详述。
在VBA代码中,可以添加用户窗体、模块、类模块。用户窗体、模块、类模块的概念和Visual Basic
完全相同。注释也与Visual Basic完全相同。
可以将光标停留在窗体、模块的任何一个子程序上,直接按“F5”运行当前子程序。

四、Word的宏的概述
Word充分地将文档编辑和VB结合起来,真正地实现文档的自动化。使用Word编程,类似于使用
Visual Basic,所不同的是,在Word中,能够直接运行某一个子程序,直接看见结果,Word的宏,
只能解释运行,而Visual Basic,现在已经能够编写成真正的机器码,从代码的保护上来说,应该尽
可能地减少Word的VBA代码数量,尤其是关键的代码。
VBA宏,可分成四种:
1、 和命令名相同的宏
如FileSave,FileOpen,如果在VBA代码中包含与Word同名的函数,则直接执行这些VBA代码,忽略Word
本身的命令。
2、 Word内特定的宏
这些宏包含AutoExec(启动 Word 或加载全局模板)、AutoNew(每次新建文档时)、AutoOpen(每次打
开已有文档时)、AutoClose(每次关闭文档时),AutoExit(退出 Word 或卸载全局模板时)。
如果VBA代码中含有这些名称的函数,则满足相应的条件,相应代码就自动执行。
3、 相应事件的VBA宏
这些宏是由事件触发的宏,如Document_Close在文档关闭的时候触发事件,Document_New在新建文档的时
候触发,Document_Open在打开文档的时候触发。
4、 独立的宏
自己编写的VBA代码,即不属于上面几种情况的VBA代码,可以被其他VBA代码调用,更重要的是,可以被
其他程序调用。
这样,我们就可以屏弃Word自动执行的宏,通过Delphi直接调用相应宏来达到目的。
五、Word命令宏的详细描述
Word本身的命令函数包含很多,但是无论是word联机帮助还是MSDN帮助,都没有这方面的介绍,因此只能
凭自己的实验取探索,初步探测的函数如下:
宏名 解释 注释
FileNew 新建
FileNewDefault 新建空白文档
FileSaveAs 另存为
FileOpen 打开
FileClose 关闭
FilePrint 打印
FilePrintPreview 打印预览
ToolsCustomize 工具栏里面的自定义
ToolsOptions 工具选项
ToolsRevisions 突出显示修订

里面有很多用词、观点也许不是特别确切,希望大家指出。
过几天再将一些具体的代码写出来(目前没有仔细整理)。
 
OleWord时一些用用的代码
yzhshi@263.net​

一、Delphi程序启动Word
采用CreateOleObjects的方法来启动Word,调用VBA代码,具体实现过程为:
首先使用GetActiveOleObject('Word.Application')判断当前内存中是否存在Word程序,如果存在,
则直接连接,如果没有Word程序,则使用CreateOleObject('Word.Application')启动Word

二、Delphi程序新建Word文稿
格式:WordDocuments.Add(Template,NewTemplate,DocumentType,Visible)
Template: 使用模板的名称,
NewTemplate: 新建文档的类型,True表示为模板,False表示为文档
DocumentType: 文档类型,默认为空白文档
Visible: 打捞的窗口是否可见

举例:Doc_Handle:=Word_Ole.Documents.Add(Template:='C:/Temlate.dot',NewTemplate:=False);

三、Delphi程序打开Word文稿
格式:WordDocuments.Open(FileName,ConfirmConversions,ReadOnly,PassWordDocument,
PasswordTemplate,Revent,WritePasswordDocument,WritePassWordTemplate,
Format,Encoding,Visible)

FileName: 文档名(包含路径)
Confirmconversions: 是否显示文件转换对话框
ReadOnly: 是否以只读方式打开文档
AddToRecentFiles: 是否将文件添加到"文件"菜单底部的最近使用文件列表中
PassWordDocument: 打开此文档时所需要的密码
PasswordTemplate: 打开此模板时所需要的密码
Revert: 如果文档已经,是否重新打开文档
WritePasswordDocument: 保存对文档更改时所需要的密码
WritePasswordTemplate: 保存对模板进行更改时所需要的密码
Format: 打开文档时所需使用的文件转换器
Encoding: 所使用的文档代码页
Visible: 打开文档的窗口是否可见

举例:
Doc_Handle:=Word_Ole.Documents.open(FileName:=Doc_File,ReadOnly:=False,
AddToRecentFiles:=False);

四、Delphi程序保存Word文稿
格式:WordDocuments.SaveAs(FileName, FileFormat, LockComments, Password,
AddToRecentFiles, WritePassword, ReadOnlyRecommended,
EmbedTrueTypeFonts, SaveNativePictureFormat, SaveFormsData,
SaveAsAOCELetter)

FileName: 文件名。默认为当前文件夹和文件名。
FileFormat 文档保存的格式。
LockComments 如果为 True,则此文档只允许进行批注。
Password 打开文档时的口令。
AddToRecentFiles 如果为True,则将文档添至"文件"菜单中最近使用的文档列表中。
WritePassword 保存对文档的修改所需的口令。
ReadOnlyRecommended 如果为 True,在每次打开文档时,Word 将建议用户采用只读方式。
EmbedTrueTypeFonts 如果为 True,则将文档与 TrueType 字体一起保存。
SaveNativePictureFormat 如果为 True,则从其他系统平台(例如 Macintosh)导入的图形仅保存其 Windows 版本。
SaveFormsData 如果为 True,则将窗体中用户输入的数据存为一条数据记录。
SaveAsAOCELetter 如果文档包含一个附加,当此属性值为 True 时,将文档存为一篇 AOCE 信笺(同时保存邮件)。

举例:
Word_Ole.Documents.SaveAs(FileName:=Doc_File,FileFormat=wdFormatDocument,
AddToRecentFiles=False);

五、从数据库读取文件到本地硬盘和从本地硬盘读取文件到数据库

在数据库上使用Image二进制字段保存,使用Stream流的方式。

创建文件流:
Word_FileStream:=TFileStream.Create(Target_Name,fmOpenWrite or fmCreate);
Word_FileStream.Position:=0;

保存到数据库的Image字段:
TBlobField(AdoQuery1.FieldByName(Column_Name)).SaveToStream(Word_FileStream);

从数据库读取文件到本地硬盘:
TBlobField(ADOQuery1.FieldByName(Column_Name)).loadfromStream(Word_FileStream);

释放文件流:
Word_FileStream.Free;

六、全局消息的定义
因为word和Delphi程序是两个软件,相互之间通讯比较麻烦,所以使用全局消息的方法进行。
全局消息必须首先注册,Windows返回系统空闲的消息号,当注册的消息相同时,
Windows系统返回同一个值,这样就保证了使用这个消息号在两个程序之间通讯。

定义消息的办法:
szMessageString: pchar = 'XIDIAN_11_Stone';
FMyJoinMessage := RegisterWindowMessage(szMessageString);

发送消息的方法:
SendMessage(对方句柄,消息,消息附带短变量,消息附带长变量)

七、Delphi程序接收消息的方法
Delphi接收消息有两种,一是重载特定消息,二是重载WndProc函数,在里面选择相应消息进行处理。
法一,每次只能处理一条消息,而法二能够同时处理多条消息。

对于法二,声明如下:
procedure WndProc(var Message: TMessage);override
必须注意,使用时需要在处理完自己消息处理后继承WndProc(Message)函数,否则系统会崩溃!

八、Word中Combo对话框的动态生成以及Change事件
建立类模块Combohander,在内部定义事件
Public WithEvents ComboBoxEvent As Office.CommandBarComboBox

定义Combo控件产生事件的模块
Dim ctlComboBoxHandler As New ComboBoxHandler

产生Combo对话框
Set Cbo_ChooseDoc = CommandBars("添加的菜单").Controls.Add(Type:=msoControlComboBox, Temporary:=True)

进行文件句柄设置,以产生Combo_Change事件
Set ctlComboBoxHandler.ComboBoxEvent = Cbo_ChooseDoc

产生事件后,在类模块Combohander内选择ComboBoxEvent的Change事件,即可书写事件代码
Sub ComboBoxEvent_Change(ByVal Ctrl As Office.CommandBarComboBox)

九、一些Word的事件
VBA代码中处理的Word事件有:Document_Close
Application事件中需要处理的有:DocumentBeforeClose,DocumentChange。

Document_Close:事件在文档关闭时产生事件
DocumentBeforeClose:在文档被关闭以前先于Word判断文档是否保存,给出相应提示并进行相应处理。
DocumentChange:文档切换,在文档从自己修改的文稿和其他人修改的文稿之间切换产生事件,
主要处理设置文档权限等。
 
自动化方面的知识
 
像你这样的好同志在DFW上已经是越来越少了。可惜DFW没有在一个贴子中给分的功能,
不然我一定给你加30分。

谢谢,收藏。
 
多谢。
其实对于技术问题,我从大富翁得到了许多,尤其是hubdog的葵花宝典,我也希望贡献自己
的一份力量,[red]众人拾柴火焰高![/red]
 
精神可嘉
 
精神可嘉,不过有些观点是错误的.例如:
使用Delphi的Server控件,Com类型库的引用和Com对象生成这三种方法实现的功能是
一样的,只是实现的形式不同而已.
 
你好,结合delphi 控件讲一下,有些参数还不明白
e-mail:jszmail@263.net
 
很好啊,若不用Server控件就不能够用delphi的code insight了.
 
写的不错,但是我想说一些不同的话,

CreateOLEObject创建的variant类型变量,运行期才通过IDispatch接口进行方法调用,所以没有Code Insight,
开发效率、运行效率都要差一点。(IDispatch接口是为适合Automation技术开发的,比COM更高级,更抽象)

Delphi Servers 组件和Import Library是一回事来着,使用Import Library会更加通用一点,除了Word,
其它的支持Automation的应用程序都可以使用,比如Autocad、IE等等。但是Import Library有很多的bug,
经常出错。这一点玩过COM编程的人都知道,但我还是推荐使用这套技术进行COM或者Automation工作,效
率高的多。hubdog是这方面的专家,你们可以等他来介绍介绍。

最后我推荐Binh Ly的站点,他是Borland的COM专家,如果经常逛Borland的Automation新闻组,你肯定认
识他,站点有很多介绍和工具下载,大家可以自己看看。Delphi 4编程技术内幕的作者Chris Clvert也是
个中好手,他的站点资料多多。

如何取消Word2000中的宏病毒提示

Word采用了宏作为其字处理系统的补充,是用户能够自己编写一部分代码来实现自己特定
的功能,大大方便了其他系统和Word之间的连接,但是同时也带来了负面的问题,人们可
以编写一些恶意的代码,危害系统的安全,从台湾No.1病毒开始到现在的美丽沙病毒,无
一不对系统造成一定危害。
为了避免这个缺点,微软提供了防病毒防护的功能,在Word97的《工具》->《选项》->《常规》
中有宏病毒防护的选项,在Word2000提供了高、中、低三种宏病毒安全级别。在Word97中
可以使用Options.VirusProtection = False来取消宏病毒防护,这样就给宏病毒提供了
机会,只要你运行过一个宏病毒,它就自动将宏病毒防护关闭,因此防护宏病毒的能力
不是太强。
在Word2000中,微软提供了宏认证的解决方案,根据证书认证机制来实现,如果宏不含有数字
签名整数,那么如果安全级别设置为高,则直接禁用宏,如果安全级别是中,则提示用户是否
启用宏,如果安全级别是无,则任何宏都能够能够运行了。
如果宏提供了认证证书,则Word将检查认证证书,判断其有效性,并提示用户是否接受该证书,
如果用户接受了该证书,则以后就不再显示使用该证书签名的宏警告。

现在问题出来了,我们自己编写的宏,如何进行认证呢?怎么进行认证呢?
通常人们会去找宏病毒安全性里面,但是在它的可靠来源列表中就是不能添加,只能删除,那么
从那里添加呢?
其实,Word提供了添加的途径,就是在Word的Visual Basic编辑器里面《工具》->《数字签名》,
选择相应证书即可.但是问题又有了,如何能够添加证书呢,通常我们打开的时候发觉可选择证书
空空的。
有两种途径可以解决这个问题,一是向证书颁发机构申请数字签名,申请的时候选择用途为代码的
数字签名就可以了,然后安装上申请下来的Cer文件直接安装就可以了,但是在打开含有此数字签
名的宏的时候,计算机必须和证书办法机构联网,否则会提示证书无效.
另一种途径是自己创建证书,Word2000提供了一个自己进行数字签名的工具:SelfCert.exe,路径
为《Office安装路径》/Office/SELFCERT.EXE,运行此文件,输入名字即可产生。
至此我们可以生成证书了,也就可以进行数字签名了。
 
就这些了!到今天为止,将我摸索Ole的所有心得都写出来了。供大家讨论吧。
帖子太长了,打开速度慢了许多。[:)]
 
多谢!!
 
这页的好资料真多,我也跟贴在这里吧。

Delphi 5 控制Excel

作者:吴晓勇,孙唏瑜
时间:2001年11月20日

(一) 使用动态创建的方法

首先创建 Excel 对象,使用ComObj:
var ExcelApp: Variant;
ExcelApp := CreateOleObject( 'Excel.Application' );

1) 显示当前窗口:
ExcelApp.Visible := True;

2) 更改 Excel 标题栏:
ExcelApp.Caption := '应用程序调用 Microsoft Excel';

3) 添加新工作簿:
ExcelApp.WorkBooks.Add;
