as already said, you ask the wrong thing, in the wrong forum...

BTW, did you have a look at the good series of articles about Steganography[^] by Corinna John ?

Where are you creating the DC, i.e. dcMem? Doesn't it ASSERT?

i've used ASSERT for CDC.but the problem is araising in the LoadImage function.hBmp is becoming NULL.

I guess that's because your m_hInstance parameter is NULL. This could be because the current application instance has not been created. Unsure | :~

Unless and until InitInstance returns successfully I don't think the instance handle will be created. Unsure | :~

If your application is dialog based
Write your code in OnDraw or initdialog of dialog instead of Initinstance() of application

Knock out 't' from can't,
You can if you think you can

How my service can impersonate Administrator (the service has access to the login information) while interacting with the Service Manager?[^]

Imagine if this were possible. It would render passwords useless. Not to mention the whole security system (since anyone could log in as admin and change whatever ACLs/settings that they didn't like)

Input "transparent" blanking window

ajf_6923-May-06 0:39

Hi, I'm writing a visual C++ application that allows a computer, running a full screen 'old' PC game, to be controlled by a remote computer.
I want to be able to blank the screen of the game machine but still control the game i.e. go into the settings screens, change player name and various other settings. Then un-blank the screen once back into the real game.

My problem is that to blank the screen I'm creating a full screen always on top window filled in black. But I still need to be able to send inputs, mouse clicks and keyboard, into the game screens. So how can I create the blanking window so that mouse clicks etc pass through it, to the game window underneath?

Thanks,

Antony

Sir,

I want to work on a project.The project is based on following utility.It will have the password option.Like in window explorer when the user right clicks at the file or folder the menu get appeared with open , rename, delete etc facilities . Now i want to add the password option.

The problem is should i use vc++ 6.0 or vc++.net 1.1 or C or anything else. Which language should be appropriate for that?

Thanks and regards

this is not a real problem. anyway, i advise you not to use VC6 but prefer VC7.1 instead, simply because of compiler standard compliance...

moreover, MFC 7.1 should be much more powerful for what you're looking for.
