If you want to get something up and running quickly, you could probably use the Windows Media
Player control. The WMP Player SDK can be found here: Windows Media Downloads[^]

If you want complete control over the media, and don't mind doing more coding, you could maybe use
DirectShow[^] and/or the Windows Media Format SDK. found at the Windows Medaia Downloads link
above.

I'm sure there's many third-party video controls you can embed as well.

Hope this helps a little.

Thanks to your suggestion, I included windows media player
control successfully, but now I am getting problem with that. I am not able to play movie inside that.
It does not resond to any of its functions like
SetFileName, SetEnabled,Play. Its buttons doesnot activate.

Sorting of items in list control is implemented in this[^] article. Check the MainDlg::OnColumnclickList1() function in it.

not data base..... to the table ... we can pass dynamic querry.. that can retrive desired sorted order of the data.....as for name
if(flg==1)// here flg shows the order u want asc=1 or desc=0
{
..
// _stprintf(xyz, _T( "SELECT NAME FROM TABLE_NAME order by NAME asc" ) );
...
}
else
{
_stprintf(xyz, _T( "SELECT NAME FROM TABLE_NAME order by NAME desc" ) );

Product architect needs to be through knowledge of the product,it's future enhancements, applicability, customer's views/needs, compititors and there drawbacks, product design and technologies used, so on....
There are no books for becoming Product architecture, you need to be working on that product and need to gain knowledge about it...

What's the drag source?

If it's the File Manager or Windows Explorer you could:

1) Call DragAcceptFiles() on the treeview control.
2) Respond to the WM_DROPFILES message in the treeview control.
3) Use DragQueryPoint() to get the cursor position where drop occurred
4) Use TreeView_HitTest() to find which item the file was dropped on
5) Use DragQueryFile() to get the name of the file dropped

I think the following should do it.

DWORD dw;<br />
dw = GetWindowLong(m_hWnd,GWL_STYLE);<br />
dw = dw & ~(WS_BORDER | WS_THICKFRAME | WS_CAPTION);<br />
	<br />
SetWindowLong(m_hWnd,GWL_STYLE,dw);<br />
<br />
int x;<br />
int y;<br />
x = GetSystemMetrics(SM_CXSCREEN);<br />
y = GetSystemMetrics(SM_CYSCREEN);<br />
SetWindowPos(NULL,0,0,x,y,SWP_NOZORDER);

To restore it, do the opposite:

DWORD dw;<br />
dw = GetWindowLong(m_hWnd,GWL_STYLE);<br />
dw |= (WS_BORDER | WS_THICKFRAME | WS_CAPTION);<br />
	<br />
SetWindowLong(m_hWnd,GWL_STYLE,dw);<br />
<br />
int x;<br />
int y;<br />
//You better save the original size and position of your window before going full screen and use those values here.<br />
x = 500;<br />
y = 500;<br />
SetWindowPos(NULL,0,0,x,y,SWP_NOZORDER);

However, take care of your windows' Z-order if you need to.

this is this.

I have to check whether the CTS signal and RTS Signal in serial port. I have modified my
dcb.fOutxCtsFlow=TRUE;
dcb.fRtsControl=RTS_CONTROL_ENABLE;
I am placing a LED between pin7(RTS) and pin5 for GND to check whether voltage occurs in that pin7. But no voltage occurs.

what is your OS?
if your OS is windows XP/2003 or later , you can work with com/parallel port directly, because this ports close by Microsoft, you can use API for this work.
