在邮件正文中发送图表 [英] Sending a chart in mail body

问题描述

我试图修改Ron de Bruins宏以在邮件正文中发送图表。首先，我导出图表并将其保存为PNG图像，然后我修改HTML代码将其添加到消息中。宏应该在服务器上运行，并发送邮件给在我工作场所工作的其他人。当我使用MailItem.Display方法，当我的消息出现时手动点击发送，一切都正常。当我尝试使用MailItem.Send方法，它不会 - 在邮件正文我得到一个图标，它试图附加一个图像，它找不到。有趣的是，当我从服务器发送邮件时，在服务器上，图表显示为核心。它不工作，只有当我尝试发送它在本地电脑。

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.

$ b $我也想提到，我试图在Send方法之后直接使用Wait函数，但是遗憾的是没有帮助。

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

推荐答案

使图像显示为内联是有可能的。 HTML中的 img src 必须使用图像的标识符引用 cid 。以下代码设置电子邮件，并将所有图表对象作为内联图像添加到电子邮件中。

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.
