vb 如何调用默认浏览器

　　默认浏览器不是IE浏览器，VB可以打开自行设置的默认浏枣慧巧览器来浏览网页。

　　可以用以下两种代码方式打开。

　　代码1)用Shell函数直接调用explorer.exe来打开网页。

　　Private Sub Command1_Click() Dim strOpen strOpen = Shell("explorer.exe "碧搏
& Text1, 1)End SubPrivate Sub Form_Load() Text1 =
"http://zhidao.baidu.com"End Sub

　　代码2)使用Api函数ShellExecute实现打开网页。

　　Option Explicit Private Declare Function ShellExecute Lib "shell32.dll"
Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal
lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String,
ByVal nShowCmd As Long) As Long Dim strUrl As String Private Sub OpenUrl(tUrl As
String) ShellExecute Me.hwnd, "Open", tUrl, 0, 0, 0End SubPrivate Sub
Command1_Click() strUrl = Text1.Text OpenUrl (strUrl)End SubPrivate Sub
Form_Load() Text1 = "http://zhidao.baidu.com/"End Sub

　　凳键两种方式都能在设置谷歌浏览器为默认浏览器状况下，打开想看的网页。
