But printDocument seems cant working well

Can you explain that further? Posting your code would also help.

Thanks hellswraith
I know there is some error, but I can't find it

My source code:
------------------------------------------------------------------------
Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

WebBrowser1.Navigate("http://www.kcg.com/doc/c_doc11.xsl")

End Sub



Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

On Error Resume Next

Dim eQuery As OLECMDF

eQuery = Me.WebBrowser1.QueryStatusWB(OLECMDID_PRINT)

If Err.Number = 0 Then

If eQuery And OLECMDF_ENABLED Then

Me.WebBrowser1.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, "", "")

Else

MsgBox("Printer Not Found or No Contents in Webbrowser")

End If

End If

End Sub
End Class

NEVER use on error resume next in VB.NET ...instead use try, catch and finally blocks..and of course that if some error happens u'd never know which and why because u have that crappy on error resume next..!

Thanks PT Exorcist.

Type "OLECMDF" is not defined.
It means no this function in vb.net

Your going to need to locate that com object and add a reference to it in order to use it. I have no idea where to look for it though. I have had problems like this before when trying to get functionality from older com components and such.
