打开ＤＥＬＰＨＩ
转到severs组件板
拉一个WordApplication1，改名为WordApplication
一个WordDocument１改名为WordDocument
转到dialogs组件板
拉一个OpenDialog1，改名为dlgopen
再拉４个button，将以下四段代码依次放入就行了
启动word时用如下代码：
begin
try
wordapplication.connect;
except
messagedlg('word may not be installed', mterror, [mbok], 0);
abort;
end;
wordapplication.visible := true;
wordapplication.caption := 'delphi automation';
end;
/////////////////////////////////////
关闭word用如下代码。如果想保存doc文件，请修改savechanges变量的内容：
var
savechanges, originalformat, routedocument: olevariant;
begin
savechanges := wddonotsavechanges;
originalformat := unassigned;
routedocument := unassigned;
try
wordapplication.quit(savechanges, originalformat, routedocument);
wordapplication.disconnect;
except
on e: exception do
begin
showmessage(e.message);
wordapplication.disconnect;
end;
end;
end;
/////////////////////////////////////
让word打开一个指定的文件，需要先放置opendialog，然后调用wordapplication.documents.open：
var
itemindex
levariant;
filename, confirmconversions, readonly, addtorecentfiles,
passworddocument, passwordtemplate, revert,
writepassworddocument, writepasswordtemplate, format: olevariant;
begin
if not dlgopen.execute then
exit;
{open document}
filename := dlgopen.filename;
confirmconversions := false;
readonly := false;
addtorecentfiles := false;
passworddocument := '';
passwordtemplate := '';
revert := true;
writepassworddocument := '';
writepasswordtemplate := '';
format := wdopenformatdocument;
wordapplication.documents.open( filename, confirmconversions,
readonly, addtorecentfiles, passworddocument, passwordtemplate,
revert, writepassworddocument, writepasswordtemplate, format );
{assign worddocument component}
itemindex := 1;
worddocument.connectto(wordapplication.documents.item(itemindex));
{turn spell checking of because it takes a long time if enabled and slows down winword}
wordapplication.options.checkspellingasyoutype := false;
wordapplication.options.checkgrammarasyoutype := false;
end;
/////////////////////////////////////
让word替换标记字符串要使用worddocument.range.find.execute，这里用delphi替换了<#name>：
var
findtext, matchcase, matchwholeword, matchwildcards, matchsoundslike,
matchallwordforms, forward, wrap, format, replacewith, replace: olevariant;
begin
findtext := '<#name>';
matchcase := false;
matchwholeword := true;
matchwildcards := false;
matchsoundslike := false;
matchallwordforms := false;
forward := true;
wrap := wdfindcontinue;
format := false;
replacewith := 'delphi';
replace := true;
worddocument.range.find.execute( findtext, matchcase, matchwholeword,
matchwildcards, matchsoundslike, matchallwordforms, forward,
wrap, format, replacewith, replace );
end;
