我对网络编程非常陌生。我正在尝试从 ASP.net 网站下载 excel。IT 不需要身份验证，但是我无法调试 URL，因为萤火虫不会像我一样请求 URL。高低搜索。对此的任何输入都会很棒。先感谢您。
行动：我点击“摘要下载”按钮下载excel。
我不知道 onClick() 去哪里了。

这是下载数据的直接方式，使用 Siddharth Rout 的路由可以适应网站的代码更改。关于“复杂部分”的最后一点。您需要做的就是使用 FindWindow 等待“文件下载”框出现，一旦您知道它已启动，您可以使用keybd_event发送 3 个选项卡和一个回车键，稍等片刻，再次按回车键和“y”如果您要覆盖文件。现在，直接下载的优点是您可以准确选择保存位置和方式。
如果您想了解更多关于我的方法的细节，我很乐意将代码发布到 StringBuffer、WriteFunction 和 DebugFunction 并解释如何从 vb 引用 libcurl。

以下是在 vb6 中使用 curl 所需的 dll 和类型库： libcurl bindings for vb6
将上述文件解压到项目目录并转到项目->引用并添加两个 tlb 文件（类型库）。
此外，这里是 vb libcurl 绑定的 sourceforge 页面，下载包括源代码和几个示例：http: //sourceforge.net/projects/libcurl-vb/

你正在尝试的有点复杂。不是第一部分，而是第二部分。
逻辑
第 1 部分）单击“摘要下载”按钮以启动“文件下载”对话框
PART 2 ) 点击“文件下载”中的保存按钮，最终保存文件
第1部分
在表单上放置一个 WebBrowser1 控件和一个按钮。粘贴此代码。
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
WebBrowser1.Navigate("http://tebb.elpaso.com/ebbmasterpage/Capacity/OperAvailAutoTable.aspx?code=TGP&name=Operationally%20Available%20Capacity&status=Cap&sParam2=M&sParam3=5/4/2012&sParam8=S")
End Sub
Private Sub WebBrowser1_DocumentCompleted(sender As Object, e As _
System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
If WebBrowser1.ReadyState <> 4 Then Exit Sub
Dim el As HtmlElement = _
WebBrowser1.Document.GetElementById("ctl00_WebSplitter1_tmpl1_ContentPlaceHolder1_sumBtnDownload")
el.InvokeMember("Click")
End Sub
现在，当您运行此代码时，它将单击“摘要下载”按钮并启动“文件下载”对话框。请参阅下面的快照。
第 2 部分 - 复杂部分
现在您需要使用 API 来单击对话框上的Save按钮。File Download幸运的是，我已经在我的博客中介绍了这一点，所以你不会有任何问题 :)
主题：VBA/VB.Net/VB6——在IE下载窗口点击打开/保存/取消按钮——第一部分
