Can i have a link between a button on an IE page and a visio event ? ( for example : changing the color of a shape just by a click on a button on the IE page)

推荐答案

不是很容易，除非您也可以访问 IE 中的 HTML 内容，但是您可以使用实现withevents"私有变量的 VBA 类来捕获对页面上特定元素的引用，该元素有一个事件处理程序来响应基于浏览器的事件.例如.在clsHTML"类中:

Not really very easy unless you have access to the HTML content in IE as well, but you could use a VBA class which implements a "withevents" private variable to capture a reference to a particular element on the page, and which has an event handler to respond to browser-based events. Eg. in a class "clsHTML":

Private WithEvents el As MSHTML.HTMLInputElement

Public Sub SetElement(t As MSHTML.HTMLInputElement)
    Set el = t
End Sub

Private Function el_onchange() As Boolean
    Debug.Print "captured change: value = " & el.Value
End Function 

在其他代码中，创建类的实例并使用对 IE 中页面上元素的引用调用SetElement":

In other code, create an instance of the class and call "SetElement" using a reference to an element on the page in IE:

Dim objHTML As clsHTML  'global variable


Sub TestEvents()
   Dim IE As Object

    'set up your IE reference....

  Set objHTML = New clsHTML
  objHTML.SetElement IE.document.getElementById("tester2")
  Debug.Print "set capture"
End Sub

在这种情况下，您将捕获文本框上的更改"事件，但其他元素将公开不同的事件....

In this instance you're capturing the "change" event on a textbox, but other elements will expose different events....

我在 Excel 中对此进行了测试，但我假设类似的东西也适用于 Visio.

I tested this in Excel, but I'm assuming something similar will also work in Visio.

Edit2:与坚持使用自动化 IE 相比，在 Visio 中创建一个表单来处理这个问题可能要好得多.

you would probably be much better off creating a form in Visio to handle this than sticking with automating IE.
