Calling INTERNET object in VB

[Btang11111]

Hi,

How do you call an instance of INTERNETEXPLORER in VB?

eg Shell( " INTERNETEXPLORER.exe ") BUT in Windows the file name is not INTERNETEXPLORER, what is it??

Also do we need to Declare the InternetExplorer Object, & how?

dim ie as object
set ie = createobject("InternetExplorer.Application")

from now on use automation to trigger IE.

Hi,

I coded IE Object, but it does not show up. Am I not using the Automation properly here to trigger IE.
Also, do I need to declare something...before I can use events like
IE_BeforeNavigate2 instead of WebBrowser1_BeforeNavigate2 (of WebBrowser Event Controls)


Thanks

you need to set
ie.visible = true
to make IE visible.

[Lothar Haensler]

here is a complete sample


option Explicit
Dim withevents ie as InternetExplorer

private Sub Command1_Click()
set ie = new InternetExplorer
ie.Visible = true
ie.Navigate2 "yourURL"

End Sub

private Sub ie_DownloadComplete()
MsgBox "downloaded"
End Sub

private Sub ie_NavigateComplete2(byval pDisp as Object, URL as Variant)
MsgBox "navigated"
End Sub





watch the WithEvents in the Dim statement. You need that to trap the events.

Hi,

Code is tidy.

I use Visual Studio v.6 BUT had this Error Msg 430 below?!

option Explicit
Dim withevents ie as InternetExplorer


Private Sub Command1_Click()
set ie = new InternetExplorerie ----->** ERROR 430 Doesn't support Automation
ie.Visible = true or Not expecting this class** interface
ie.Navigate2 "yourURL"
End Sub

private Sub ie_DownloadComplete()
MsgBox "downloaded"
End Sub

private Sub ie_NavigateComplete2(byval pDisp as Object, URL as Variant)
MsgBox "navigated"
End Sub

sorry, you need to add a reference to shdocvw.dll to make it work.
That DLL contains the InternetExplorer "object".

Hi,

same Error Msg 430 after replacing INTERNETEXPLORER with SHDocVwCt1.INTERNETEXPLORER.
Pls show REFERENCE codes for SHDocVwCt1.

OR perhaps we need to create an EVENT SINK, & hook the EVENT SINK with an instance of the INTERNETEXPLORER??



option Explicit
Dim withevents ie as SHDocVwCtl.InternetExplorer

private Sub Command1_Click()
set ie = new SHDocVwCtl.InternetExplorer **ERR MSG 430 **

ie.Visible = true
ie.Navigate2 "yourURL"
End Sub

private Sub ie_DownloadComplete()
MsgBox "downloaded"
End Subprivate Sub

ie_NavigateComplete2(byval pDisp as Object, URL as Variant)
MsgBox "navigated"
End Sub

Hi,


Thanks very much, WELL DONE! It works after I click on Reference Command (instead of Component Command)in Project Menu, Scroll to Microsoft internet Control (shdocvw.dll) reference & check the check box.
