使用TWordApplication控件控制WORD的问题(封装成一个类)

[happy243]

我想写一个WordControl类
内部封装TwordApplication和TwordDocument

主要属性
CurrentDoc:OleVariant;//当前文档的数据 只读 (GetDocData)
CurrentDocIndex:integer;//当前文档索引
CurrentDocName:String; //当前文档名称
DocCount:integer; 当前打开的文档数目
DocsStly::array [0.. DocCount-1] of Char //文档的打开类型；由L:由对象打开 R：由用户手工打开
Document: TwordDocument; //当前文档对象

希望能够实现以下方法

Create:初始化对象，并创建WORD
Destory：释放对象内的所有资源
OpenDoc:打开一个文档
GetDocData：获得指定文档的数据
SaveDocToDisk：保存文档的磁盘
ReplaceTextToDoc：替换文档中的指定信息
WriteTextToDoc: 向文档指定位置添加指定文字
PrintDoc：打印指定文档
RefreshDoc：刷新指定文档


希望各位高手不吝赐教，集思广益，一起来完善

我先写点吧，感觉效果不大好

unit WordControl;

interface

uses
Classes, SysUtils, Variants, Word2000, Office2000;

type
TWordControl = class
private
FCurrentDocIndex: Integer;
FCurrentDocName: String;
FDocCount: Integer;
FDocument: TWordDocument;
protected
FWordApplication: TWordApplication;
FWordDocument: TWordDocument;
public
FDocsStyle: array of Char;
//文档的打开类型 L :由对象打开 R: 由应用程序打开

constructor Create(shown: Boolean = True); //是否显式调用，默认为是
destructor Destroy; override;

function GetDocData(): OleVariant;
function OpenDoc(ADocName:WideString): Integer; overload; //打开外部文件
function OpenDoc(ADocName:WideString ;ADocData: OleVariant): Integer; overload; //打开数据库文件
function SaveDocToDisk(ADocName: WideString): Integer;
function ReplaceTextToDoc(AdocName,AOldText,ANewText:String): Boolean;
procedure PrintDoc(); //打印当前活动文档
procedure PrintViewDoc(); //打印预览当前活动文档
procedure RefreshDoc(); //刷新文档


published
property CurrentDoc: OleVariant read GetDocData; //获得当前文档的内容
property CurrentDocIndex: Integer read FCurrentDocIndex; //当前文档索引
property CurrentDocName: String read FCurrentDocName; //当前文档名称
property DocCount: Integer read FDocCount; //当前打开的文档数目
property Document: TWordDocument read FDocument;
//当前的文档对象，此外是为方便实际应用中进一步的对文档的控制要求。
//property DocsStyle: array of char read FDocsStyle;
end;

implementation

{ TWordControl }

constructor TWordControl.Create(shown: Boolean);
//var

FDocCount := 0;
end;

destructor TWordControl.Destroy;
begin
if Assigned(FWordApplication) then
FWordApplication.Free;
if Assigned(FWordDocument) then
FWordDocument.Free;
inherited;
end;

function TWordControl.GetDocData: OleVariant;
begin
Result := Variant(FWordDocument.Content as IDispatch);
end;

function TWordControl.OpenDoc(ADocName: WideString): Integer;
var
FileName,i : OleVariant;
begin
FileName := ADocName;
FDocCount := FDocCount + 1;
i := FDocCount;
FWordApplication.Documents.Open(FileName,EmptyParam,EmptyParam,
EmptyParam,EmptyParam,EmptyParam,EmptyParam,
EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam);

end;

procedure TWordControl.PrintDoc();
var

FWordDocument.PrintOut;
end;

procedure TWordControl.PrintViewDoc();

FWordDocument.PrintPreview;
end;

procedure TWordControl.RefreshDoc;
begin
FWordDocument.Reload;

FWordDocument.Disconnect;
FWordDocument.ConnectTo(FWordApplication.Documents.Item(i)); }
end;

MatchWildcards, MatchSoundsLike, MatchAllWordForms,
_Forward, Wrap, Format, ReplaceWith,

end;

function TWordControl.SaveDocToDisk(ADocName: WideString): Integer;
var
SaveChanges: OleVariant;

begin
SaveChanges := wdSaveChanges;
FileName := ADocName;
//FWordApplication.Quit(SaveChanges);
FWordDocument.SaveAs(FileName);
FWordDocument.Close(SaveChanges);
//FWordApplication.Visible := False;
//FDocCount := FDocCount - 1;
Result := 0;
end;
