用CreateOLEObject建立了一个WordApp后如何监视Word是否关闭了

[MINJI]

用CreateOLEObject建立了一个WordApp：
WordApp:= CreateOLEObject('Word.Application');
WordApp.Visible:=True;

之后如何监视Word是否关闭还是继续打开？

在进程中判断

为何不用D5自带的控件，如果嫌他不好，可以看看delphi的demo路径如下：
C:\Program Files\Borland\Delphi5\Demos\Activex\Oleauto\Word8
尤其是autoimpl.pas（可是原理哦）

delphi自带了一个简单的word例题，但功能太简单。通过查找vba的说明，再对照delphi的vcl，编写了如下代码，实现了基本的公文管理功能。

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 :olevariant;
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;

上面这4段代码完成了公文管理的基本功能，再把它和数据库结合起来，就可以开发一个与lotus notes类似的产品了
