There's an excellent free online book (Bruce Eckel's Thinking in C++) at:

Oh, and by looking at your program, you're going to need it :P

How do I delete the history in a ChtmlView? Also, how do I found out what drives are active (i.e. A:, D:, …)? I need to make a program that have an icon representing the drives and the user is able to open the drives.
Thank you

Maybe you should use the DriveListBox control

DVD Files / Burning

Does anyone know how to write a program to burn a DVD, using some API or COM interface?

Also, on a related note, where can I find information on the format of the .VOB and .IFO files that make up a DVD?

Sorry if I am just missing something obvious. I have been known to do that some times. Blush | :O

Have you looked into the Nero SDK/API[^]? It does both CD's and DVD's.

Thanks! Even better yet, I have nero!

Anyway, that appears to solve my problem with burning the disc. It does not seem to be able to generate the .vob and .ifo files required for the DVD.

What I want to do is write a program that will capture video, synchronize the A/V streams, and convert it to DVD format. Ideally, I could capture video directly into a DVD-compatible format. If anyone can help me there, that would be appreciated.

Thanks,

VK_RETURN and VK_DELETE (as defined in WinUser.h)

I would handle them in the TVN_KEYDOWN notification handler

void CMyDialog::OnKeyDownTree(NMHDR* pNMHDR, LRESULT* pResult)
{
    NMTVKEYDOWN* pTVKeyDown = (NMTVKEYDOWN*)pNMHDR;
    if (pTVKeyDown->wVKey == VK_RETURN)
    {
        // Enter Key
    }
    else if (pTVKeyDown->wVKey == VK_DELETE)
    {
        // Delete Key
    }
    *pResult = 0;
}

If you have a handle to the process, you can use the Win32 function GetProcessTimes. However, it only works on NT/2K/XP systems. Smile | :)

what files to distribute with my MFC app?

I am wondering what files to distribute with my MFC app to get it to work on various different machines. In my project settings, it says I am using MFC in a shared DLL. When I go to run my app on my XP (versus my 98 where I developed it), it doesn't work.

So, obviously I need to distribute some files, but which ones?

Thanks.

Use Dependency Walker on your EXE to tell what DLLs it uses. This comes with VC 6 (not sure about 7.x since I don't use them), or you can get the latest version from dependencywalker.com[^]

still doesn't work

I used dependency walker. I copied the files: mfc42.dll and msvcrt.dll from my visual C++ CD and put those in my target machine's system folder. I also copied the release version of my app onto the target machine and it still doens't work. The target machine is WinXP and when I run my app it comes up with some dialog box that really doesn't explain the error.

**EDIT**
I looked up in MSDN about this and they said I had to register my DLLs on the target machine. How do I do this?

Any more help is appreciated. Thanks.
