Navigate and Navigate2 of InternetExplorer in Windows Seven

Hi,

With the new version of Windows (Windows 7 Professional and Windows 7 Enterprise), the call to Navigate2 and Navigate function of InternetExplorer object does not function.

The program opens a new IE with POST params. With the new OS, after do the call to Navigate or Navigate2, as soon as the InternetExplorer is shown, it closes. I check that this call only fails when I pass params in POST. The programs runs perfect in other OS (Windows Vista and Windows XP).

Important: Setting the Compatibility of program who launchs this DLL to 'Windows XP ServicePack3', call runs good.

¿Somebody knows why?

The code of my application looks like this:

Public Function AbrirPaginaPortal(URLPortal As String, Page As String, CodClient As String, UserId As String, Password As String, EsperarCierre As String, IEVisible As String, SaveXmlAs As String, Optional ShowWindowConect As String = "", Optional ShowErrors As String = "", Optional Error As String = "") As Boolean

On Error GoTo ErrorAbrirPaginaPortal

Dim strPostData As String
Dim strHeader As String

'Make the Post Data String
strPostData = "UserID=" + Trim(UserId) + "&UserPass=" + Trim(Password) + "&ToPageTask=" + Replace(Trim(Page), "&", "#@#")
Dim absPostData() As Byte

absPostData() = StrConv(strPostData, vbFromUnicode)

'Post the data
If AbrirIE = True Then
If IEEsVisible = "1" Then
oIE.Visible = True
End If

oIE.Navigate2 Trim(URLPortal) + "A3FisLoginEx.aspx?CL=" + CStr(CLng(CodClient)), 0, "", absPostData(), strHeader


End If

Set oIE = Nothing

On Error GoTo 0
Exit Function
ErrorAbrirPaginaPortal:
Set oIE = Nothing
On Error GoTo 0
Exit Function
End Function

I created a new instance (without embed the InternetControl object to form).

Hi Exddds, Can you please tell me in detail what you did to solve this problem. I have similar problem but I am using C#.net. Perhaps your code helps me.

Looking forward for your reply.

Thank You.
