打印留存，但在打印时却遇到了麻烦，那就是汉字中的空格成为多余。以下Delphi程序利用Memo 控件作为过渡，可删除文件中的多余空格，重新存盘后，即可方便的用Word或Wps打印输出。 <p> 1、新建一个工程，在窗体上放置如下控件：Memo1、OpenDialog1 和3个按钮（“打开”、“存盘”、“删除多余空格”），设置Memo1的属性WordWrap=False，设置“存 盘”和“删除多余空格”的属性Enabled=False。 <p> 2、编写三个按钮的事件代码。 <pre>procedureTForm1.ToolButton1Click(Sender:TObject);begin//打开一个文本文件ifopendialog1.Executethenbeginmemo1.Lines.LoadFromFile(opendialog1.FileName);caption:='DeleteBlank['+opendialog1.FileName+']';ifmemo1.Lines.Count<>0thenbegintoolbutton2.Enabled:=True;toolbutton3.Enabled:=True;endelsebegintoolbutton2.Enabled:=False;toolbutton3.Enabled:=False;end;end;end;procedureTForm1.ToolButton2Click(Sender:TObject);begin//将Memo1的内容写入原来文件screen.Cursor:=crHourGlass;memo1.Lines.SaveToFile(opendialog1.FileName);toolbutton2.Enabled:=False;screen.Cursor:=crDefault;end;procedureTForm1.ToolButton3Click(Sender:TObject);vari,j,linecount,strlen:integer;buffer1,buffer2:string;begin//删除Memo1中的多余空格screen.Cursor:=crHourGlass;linecount:=memo1.Lines.Count;//总行数fori:=0tolinecount-1dobegin⌨️
