Delphi与Word（三）取得Word文件的数据

//取得Word文件的数据
procedure getWordStr;
var WordApp: TWordApplication;
    WordDoc: TWordDocument;
    DocInx,oFileName,CfCversions,oReadOnly,AddToRctFiles,PswDocument,
    PswTemplate,oRevert,WPswDocument,WPswTemplate,oFormat: OleVariant;
    i,iRow,iCol:integer;
    myCell:Cell;
    myRow:Row;
begin
  memo1.Lines.Clear ;

    // ===== 创建对象 =====
    if not Assigned(WordApp) then                         
    begin
      WordApp:= TWordApplication.Create(nil);
      WordApp.Visible := false;
    end;
    if not Assigned(WordDoc) then
      WordDoc:= TWordDocument.Create(nil);
  try
    DocInx:=1;
    oFileName := 'd:\test.doc';
    oReadOnly:=true;
    CfCversions := EmptyParam;
    AddToRctFiles:= EmptyParam;
    PswDocument:= EmptyParam;
    PswTemplate:= EmptyParam;
    oRevert:= EmptyParam;
    WPswDocument:= EmptyParam;
    WPswTemplate:= EmptyParam;
    oFormat:= EmptyParam;    
    // ===== 打开文件 =====                        
    WordApp.Documents.open(oFileName,CfCversions,oReadOnly,AddToRctFiles,
       PswDocument,PswTemplate,oRevert,WPswDocument,WPswTemplate,oFormat);
    // ===== 关联文件 =====
    WordDoc.ConnectTo(WordApp.Documents.Item(DocInx));

    //方法(1): 取整个文本的字符内容，包含表格
    s := WordDoc.Range.text; 

    //方法(2): 取 1 -- 4 位的字符 ，包含表格
    myRange:=WordDoc.Range;
    myRange.Start:=0;
    myRange.End_ :=4;

  finally
    if Assigned(WordDoc) then              // ===== 关闭文件 =====
    begin
