IHTMLrender and drawtodc

Question

Hi, I am having problems with using the DrawToDC of the MSHTML.iHTMLElementRender in a VB.net application. For some reason I am getting a "catastrophic error". I am basing the code on c# examples, and I am not sure what exactly I am doing wrong. From the C# posts it seems that the drawtodc has a bug and you need to redifine it, so i followed their advice and specified an interface as below but without any luck: Imports System Imports System.Drawing Imports System.Runtime.InteropServices Imports mshtml _ Interface IHTMLElementRender Sub DrawToDC(<[In]()> ByVal hDC As IntPtr) Sub SetDocumentPrinter(<[In](), MarshalAs(UnmanagedType.BStr)> ByVal bstrPrinterName As String, <[In]()> ByVal hDC As IntPtr) End Interface 'IHTMLElementRender On the main form of the application I am have the folowing code when a button is clicked: Dim objMSHTML As HTMLDocument Dim objDocument As IHTMLDocument2 Dim ips As IPersistStreamInit objMSHTML = New HTMLDocument() ips = DirectCast(objMSHTML, IPersistStreamInit) ips.InitNew() objDocument = objMSHTML.createDocumentFromUrl("http://www.google.com", String.Empty) Do Until objDocument.readyState = "complete" Application.DoEvents() Loop MsgBox(objDocument.body.outerHTML) Dim bodyElement As IHTMLElement Dim render As IHTMLElementRender If objDocument.body.outerHTML <> Nothing Then bodyElement = objDocument.body render = bodyElement Dim img As New Bitmap(600, 400) Dim g As Graphics = Graphics.FromImage(img) Dim memDC As IntPtr memDC = g.GetHdc() Try render.DrawToDC(memDC) Catch ex As Exception MsgBox(ex.ToString) End Try End If It seems like I am getting the HTML document just fine, is just that when I try to use DrawToDC to get the application to print/send to the DC i Created in memory, it causes the error. Any ideas on what I am doing wrong? From the dotnet newsgroups I was told I am not hosting MSHTMl fully and that might be the cause . I was told that I should use either the internetexplorer/webbrowser controls or the MSHTMl fully. I cannot find any source on the web on how to do this in vb.net I tried the following but this also failed. Dim browser As New SHDocVw.InternetExplorer() browser.Navigate("http://www.google.com") Do Until browser.ReadyState = 4 Application.DoEvents() Loop Dim objDocument As IHTMLDocument2 = browser.Document MsgBox(objDocument.body.outerHTML) Dim bodyElement As IHTMLElement = objDocument.body Dim render As IHTMLElementRender = bodyElement Dim img As New Bitmap(600, 400) Dim g As Graphics = Graphics.FromImage(img) Dim memDC As IntPtr memDC = g.GetHdc() Try render.DrawToDC(memDC) Catch ex As Exception MsgBox(ex.ToString) End Try Here are the links to where I got the C# examples: http://groups.google.com/groups?hl=en&lr=&threadm=a299f931.0406011058.43b92799%40posting.google.com&rnum=5&prev=/groups%3Fnum%3D100%26hl%3Den%26lr%3D%26q%3DDrawToDC%2B%2Bfailure http://blogs.msdn.com/rfarber/archive/2004/10/12/240943.aspx thanks
