如何在VB6中使Internet Explorer不可见？

这样做:

Shell ("C:\Program Files\Internet Explorer\iexplore.exe -embedding http://www.websiteurl.com")

不起作用我需要它,因为我基本上需要它能够重定向并提示用户下载文件.有任何想法吗？

Internet Explorer公开了可以使用的COM可访问接口.如果你真的需要.我建议反对它 - 它相对缓慢,容易出错,繁琐且资源密集.

更优雅地解决您的问题的是使用WinHTTPRequest.在您的项目中,引用"Microsoft WinHTTP Services,版本5.1",然后继续这样:

Dim HttpRequest As New WinHttp.WinHttpRequest
Dim TargetUrl As String
Dim TargetFile As String
Dim FileNum As Integer

TargetFile = "C:\foo.doc"

TargetUrl = "http://www.websiteurl.com"
HttpRequest.Open Method:="GET", Url:=TargetUrl, Async:=False
HttpRequest.Send

If HttpRequest.Status = 302 Then

  TargetUrl = HttpRequest.GetResponseHeader("Location")
  HttpRequest.Open Method:="GET", Url:=TargetUrl, Async:=False
  HttpRequest.Send

  If HttpRequest.Status = "200" Then

    FileNum = FreeFile
    Open TargetFile For Binary As #FileNum
    Put #FileNum, 1, HttpRequest.ResponseBody
    Close FileNum 

    Debug.Print "Successfully witten " & TargetFile
  Else
    Debug.Print "Download failed. Received HTTP status: " & HttpRequest.Status
  End If
Else
  Debug.Print "Expected Redirect. Received HTTP status: " & HttpRequest.Status
End If

硬编码"C:\foo.doc"当然没有多大意义.我将使用服务器在响应标头中提供的文件名("Content-Type"或者"Content-Disposition",取决于您的期望).
