How To Cause Navigation to Occur in Same WebBrowser Window

SUMMARY
When hosting the Internet Explorer 4.x or later WebBrowser control in a Visual Basic application, you may want to have the navigation always occur in your application and not other Internet Explorer windows. If you handle the NewWindow2 event and set the Cancel flag equal to True, navigation is
canceled completely. Since NewWindow2 does not provide you with the URL to
navigate to as the Internet Explorer 3.x NewWindow event did, there doesn't
appear to be any way to have the navigation occur in the same window.
Fortunately, Internet Explorer 4.x or later provide the WebBrowser_V1 object for compatibility with Internet Explorer 3.x. Using the WebBrowser_V1 object, you can have your application receive events from version 3.x, 4.x, and 5.x. That means that you can handle the version 3.x NewWindow event and then have the navigation occur in the current window.

MORE INFORMATION
In order to implement this functionality in your Visual Basic application,
follow these step:
| 1. | Create a form with a WebBrowser control on it.
|
| 2. | In the declarations section of that form, add the following:
Dim WithEvents Web_V1 as SHDocVwCtl.WebBrowser_V1
|
| 3. | In the Form_Load event, add the following:
Set Web_V1 = WebBrowser1.Object
WebBrowser1.Navigate2 "http://www.microsoft.com"
|
| 4. | After the NewWindow2 event fires, the Web_V1_NewWindow event will fire
with the linked URL as one of its input arguments. Remember not to set
Cancel to True in NewWindow2. Also, set the Processed variable to True
in the NewWindow event handler so that a new instance of Internet
Explorer will not be created. The following code shows this event
handler and the code necessary to navigate within the current window:
Private Sub Web_V1_NewWindow(ByVal URL As String, _
ByVal Flags As Long, _
ByVal TargetFrameName As String, _
PostData As Variant, _
ByVal Headers As String, _
Processed As Boolean)
Processed = True
WebBrowser1.Navigate URL
End Sub
|
| 5. | Right-click a link and select "Open in New Window" and you will find the link will still open inside your WebBrowser Control.
Please note that Internet Explorer does not fire a NewWindow or NewWindow2
event when the user presses CTRL+N or points to New under the File menu and
clicks Window.
