I'm maintaining a legacy program using Visual C + + 6.0. I want to bypass the username or password dialog box of Explorer for which I followed the article
http://support.microsoft.com/kb/320153.
But my problem is that I never get the Authenticate event
thanks in advance
Here is my code:
// File header:
class CWebBrowser : public CWnd
{
private:
CWnd * m_pParent;
...

DECLARE_DYNCREATE(CWebBrowser)
public:
CLSID const& GetClsid(int control = 0) // 0 = WB, 1 = IE
{
// 0002DF01-0000-0000-C000-000000000046
static CLSID const clsid_IE
= { 0x0002DF01, 0x0000, 0x0000, { 0xC0, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x46 } };
// 8856f961-340a-11d0-a96b-00c04fd705a2

= { 0x8856f961, 0x340a, 0x11d0, { 0xa9, 0x6b, 0x00, 0xc0, 0x4f, 0xd7, 0x05, 0xa2 } };
return control ? clsid_IE : clsid_WB;
}
CWebBrowser();
~CWebBrowser();
