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.

Thanks! BTW, wich one is nomaly using, what are they differenct?

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 />

Just curious - are you using a CWebBrowserCtrl expressly for the purpose of getting at the page's HTML?

If you aren't using the CWebBrowserCtrl to display the page to the user, you may want to see this[^] article.

Ok, so what's your question? Is this a console or GUI application?

One way to do this is to do in the C style by using getch() function to enter the charater. getch() function do not display character on the screen.

char passwd[15];
int i=-1;
printf("Enter Password:");
do
{
passwd[++i] = getch();
} while(passwd[i] != 13);
passwd[i] = '\0';

printf("\npassword is %s\n",passwd);

13 is the ascii code for the return key. Hope it will work Smile | :)
