This is what the documentation says -
Bit position 0 is drive A, bit position 1 is drive B, bit position 2 is drive C, and so on.

You can get the available drives using bit manipulation.

if (my_variable & 1)
{
   // Drive A: available
}
if (my_variable & 2)
{
   // Drive B: available
}
if (my_variable & 4)
{
   // Drive C: available
}

You could do this in a loop.

cout << "Available drives -\n";
for (DWORD i = 0; i < 26; ++i)
{
   if (my_variable & (1 << i))
   {
      cout << char(65 + i) << ":\n";
   }
}

The toolbar sends the WM_COMMAND[^] which is the same as that for menus and accelerators.
Look at the last row of the table in the remarks section of the documentation.
The low word of wParam contains the ID of the toolbar and the high word contains the notification code like BN_CLICKED.

You could either start at MSHTML Reference[^] or by looking at the IHTMLDocument2[^] interface.

How to create context menu, that shows up when right mouse button was clicked on a file in Windows Explorer? It is important to do this using native Win32, without MFC, WTL, Afx or CLR.

Explorer already creates a context menu when you right click on a file or folder. If you want to extend or interact with the context menu then you should read the article by Michael Dunn. It contains everything you need to know regarding shell extensions.

I need to display explorer context menu in my program. I do not need to extend or modify it. "The Complete Idiot's Guide to Writing Shell Extensions" it is all about how to extend or modify, but i do not need it.

BOOL showContextMenu (HWND hWnd, TCHAR* fullPart)
{
    // ... 
    return TRUE;
}

Ok I am sorry but I dont understand your question. Your original question asked how to create a popup context menu[^] when you right click a file in windows explorer[^]?

I am looking for an example of code for getting video "capture" from camera to AVI file using AVI stream in plain C++. I need to use the camera data as document (file) in MFC.
There is plenty of sample code (and applications) in here but they all either use C# ,framework library or just read from AVI file.

Thanks for reading Vaclav
