您的程序在wondows 2000中执行正常，
为什么在WINDOWS 98中不正常

测试过的，可以用，你在form上放一个button

to terry_lzs:
真是是很奇怪，我在 windows 2000能正常通过
但是我在中文windows 98 英文windows中都试过了
在运行时仅仅是屏幕闪了一下，没有启动 outlook
这是我写的您帮助我看一看,其中FUNCTION SendEMail的位置加对了没有？
unit Unit1;

end;




procedure TForm1.Button1Click(Sender: TObject);

mail.Free;

end.

 
另外下面一段程序您能调试通过吗？

const olMailItem = 0;
var Outlook: OLEVariant;
MailItem: Variant;
begin

try
Outlook := GetActiveOleObject('Outlook.Application');
except
Outlook := CreateOleObject('Outlook.Application');
end;

MailItem := Outlook.CreateItem(olMailItem);
MailItem.Recipients.Add('mshkolnik@rs-ukraine.kiev.ua');
MailItem.Subject := 'your subject';
MailItem.Body := 'Welcome to my homepage:http://www.geocities.com/mshkolnik';
MailItem.Attachments.Add('C:/Windows/Win.ini');
MailItem.Send;
Outlook := Unassigned;
end;
 
1、同样的代码，我在办公室 windows 2000中一点问题没有
在家里windows 95中却不行。
2、思前想后，我想在家里是不是因为安装了FOXMAIL软件的原因？
后来我将outlook也配置好，并设置为默认邮件程序，却还是不行
为什么？outlook还要怎样配置，我的WINDOWS 98 的VERSION 为4.10.2222A
3、第二段代码我测试也通不过，似乎还是outlook没有配置好，难道您的outlook
是单独安装的，我是在安装windows 98 时自动安装上去的，从来没有改过
 
mycwcgr：你的問題已經過期，請自己提前或結束，謝謝
 
另外一段调用是OFFICE里的OUTLOOK，
而你前面的第一段程序是根据你默认的邮件系统来的。
 
多人接受答案了。
