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.

Need help regarding serial Communication Programming

Re: Need help regarding serial Communication Programming

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.

Please give more details.

I think you need to:
1. Open the serial port (CreateFile)
2. Get the state of the DCB (GetCommState)
3. Set dcb.fOutxCtsFlow and dcb.fRtsControl
4. Set the state of the DCB (SetCommState)

Are you doing all of these?

I meant, we need more details about what you are doing in your program - a longer code section, maybe.

Once you set the parameters in the DCB, did you do:

SetCommState(hPort, &dcb);
