You'll probably need the DirectX SDK. DirectShow has some examples that capture from cameras and display the output in a window (see the playcap example)

If you can think - and not make thoughts you aim;

so any suggestion please ?
thank u !

use __int64 for big numbers, for very big numbers you have to code an own lib.
Don't try it, just do it!

OLE/COM DECIMALs can hold 96 bit numbers. Take a look at the docs in MSDN.

Look into Audio part of this site.

The simplest way to play an audio file on windows is to use the PlaySound function.

Putting a bitmap on a button? Depends on whether you're using mfc, wtl, win32 api, .net or something else. There's probably a dozen tutorials on this site alone explaining it, though.

I have an username & password inside my exe file. I opened it with notepad and saw they are in pain text somewhere inside it. Somebody told me that there is an compiler option that encrypt variables or something like this. Is there such a thing exist or he sucks?

nothing like that... encrypt it using a PE crypter or just save the MD5(or other) hash of the password.

Well, then the Key is visible and could be decrypted, but of course with a little more job.

As far as I know, there is no such compiler option. Your 'somebody' may have been thinking of an option to obfuscate .NET code.

If you embed a password directly into an exe, it will be insecure. You can play with it to make it less obvious (e.g. XOR against some other non-secret value), but nothing you can do will actually make it secure. If the exe has access to the password, so does anyone who has the exe.
|
|
|
|
|
If you absolutely must hard-code a password in the exe file, then I recommend you encrypt it, and then store the encrypted version in the exe. Then whenever you need to compare against it, encrypt the user-entered password and compare the encrypted passwords. I wouldn't do anything with plain-text passwords except encrypt them.

I have a SDI application with a splitter (left and right views). Left view is regular view(CView) created by the wizard. Right view is a form view with a pie chart drawed on it. Everytime i try to select File > New, it will give me assertion error. This is because of the pie chart, if i take out the drawing of the pie chart class on the right view then it works fine. However i need the pie chart to stay on there. How can i make this so when i hit File > New, it will try to open a new document on the Left view only and right view will not be reload or affected.

The trick here is to remember that debug asserts are your friend. Let the assert happen and use the debugger to examine the line that asserts. If it's deep in MFC (probably is) there are probably comments in the source explaining what's being asserted and why it might fail. It's those conditions you need to investigate to deal with the assert.

You are thinking of a "wizard", I think.
Look up CPropertyPage / CPropertySheet in MSDN documentation. Or look in the Programmers
Guide section for something like "programming a wizard".
