在邮件正文中发送图表

Im trying to modify Ron de Bruins macro to send a chart in mail body. First, I export chart and save it as an PNG image, then i modify HTML code to add it to the message. Macro should run on a server and send mails to other people working in my workplace. When Im using MailItem.Display method and manually click "send" when my message appears, everything works fine. When I try to use MailItem.Send method though, it doesnt - in mail body I get an icon like it tried to attach an image which it couldnt find. Whats funny, when I send that mail from a server, on a server acount, chart is displayed corectly. It doesnt work only when I try to send it on "local" computers.

我试图修改Ron de Bruins宏来发送邮件正文中的图表。首先,我导出图表并将其保存为PNG图像,然后我修改HTML代码以将其添加到消息中。 Macro应该在服务器上运行,并将邮件发送给在我的工作场所工作的其他人。当我使用MailItem.Display方法并在我的消息出现时手动点击“发送”,一切正常。当我尝试使用MailItem.Send方法时,它没有 - 在邮件正文中我得到一个图标,就像它试图附加一个它无法找到的图像。有趣的是,当我从服务器发送邮件时,在服务器帐户上,图表显示为corectly。它只在我尝试在“本地”计算机上发送时才起作用。

I also want to mention, that I tried to use Wait function directly after Send method, but sadly it didtnt help.

我还想提一下,我试图在Send方法之后直接使用Wait函数,但遗憾的是它没有帮助。

Getting the images to appear as inline is certainly possible. The img src in the HTML must refer to the cid with an identifier for the image. The code below sets up the email and adds all of the chart objects as inline images to an email.

使图像显示为内联当然是可能的。 HTML中的img src必须引用带有图像标识符的cid。下面的代码设置电子邮件,并将所有图表对象作为内联图像添加到电子邮件中。

Excellent! I couldn't manage to attach the active workbook into the mail. I tried to add the code .Attachments.Add (ActiveWorkbook.FullName) but didn't work, I received a message saying that the file is in use, and sometimes Runtime error 424 - Object required

优秀!我无法将活动工作簿附加到邮件中。我试图添加代码.Attachments.Add(ActiveWorkbook.FullName)但没有工作,我收到一条消息说文件正在使用,有时运行时错误424 - 需要对象

With olMail
    .To = "[e-mail]"
    '.CC = "xxxx@xxx"
    .Subject = "xxxx"
    .Attachments.Add (ActiveWorkbook.FullName) ' this i added
