Re: How to auto logon to a website?

I do that for some websites.
I use a Proxomitron filter that inserts my username and
password as 'value' arguments in the appropriate
fields of the login . It also adds a javascript
function ( formsubmit()--which automatically submits the
form ) and inserts an "onload" call to formsubmit() it
the tag.

You could probably do it with GreaseMonkey or Privoxy too.

Whoops, sorry. Though I was in the lounge.
Didn't realize this was a C++ question.

I have several .vbs files that do that for various Web sites that require authentication. I don't know how to do that with VC++, however.

You need to create an owner drawn control for this. Or download one, there are plenty about.

Debug Assertion failed- Context Sensitive Help??

I'm developing an application using MFC. I've implemented Context Sensitive
Help using HTMLHELPW function.
On the right click of the mouse on any of the controls a help message is
displayed.
The problem I'm facing is :- Whenever a user randomly right clicks on
several different controls an Debug Assertion Failure message is displayed
and the execution of the application is broken.
On deugging the application it is found to break at Wincore.cpp file.
I'm providing the Lines of code in Wincore.cpp where the failure occurs:

m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();

In debug window it displays:
Unhandled exception at 0x7c34055c (MFC71UD.DLL) in Application.exe: User
breakpoint.
File: wincore.cpp
line 880

Any idea how this problem can be resolved?

Thanks

In VC++ v6, I do not see an assertion on line 880 of wincore.cpp. Are you using some other version of VC++?

GetObject[^]

The BITMAP[^]structure has a pointer to the bitmap bytes, once GetObject has filled it in. If it does not work, you need a DIBSection, create one and copy your image onto it, then you can pass that HBITMAP to GetObject, or if you called CreateDIBSection[^]yourself, you'll already have a pointer to the bytes.

Use the function GetBitmapBits() which returns the the bits in an Byte array
or u can read a bitmap like any other ordinary file.

I would hazard a guess that it's possible using the IWebBrowser2 interface but have never tried.

It is not valid to exit from an MFC program in this manner from within the MainFrame window. You should post yourself a WM_CLOSE or else use PostQuitMessage() instead.

PostQuitMessage usually works if your thread has a message queue but does not have a window. You definitely have a window, so I would post the WM_CLOSE instead.

PostMessage(WM_CLOSE);

Or you can use the sample code from MSDN:

//The following line send a WM_CLOSE message <br />
//   to the Application's main window. This will cause the<br />
//   Application to exit.<br />
AfxGetMainWnd()->PostMessage(WM_CLOSE, 0, 0);<br />

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
