Hi,
I have lauchned an application B from my application A using ShellExecute() , it will return a Handle.
How can I track in application A that application B is closed at certain stage?
Thanks
Regards.

First of all what type of application you are creating.
Here you can chect the value of handle....
check if it exist...

Does it means that If when 2nd application is closed then the handle returned by ShellExecute will automaticlay become flase or expired or null.

I don't think there is an easy way to track an application. The Handle returned by ShellExecute() is not a handle, but a value.
There are other ways you can track an application like: Events, Mutexes etc.
this is this.

You may keep track of process by enumrating the running processes in specific time stamp.
Knock out 't' from can't,
You can if you think you can

if u r application happens to be an .exe then u can get Processid.Using it u can track application B in Application A.This might help u.
never say die

|

Process32First and Process32Next to get the Processid:->
never say die

In order to see that a process was closed, you need its "handle". Please compare ShellExecuteEx and CreateProcess in order to see which is more suitable to obtain the handle. Then use the handle in the following mode:
if(::WaitForSingleObject(handle, 0) == WAIT_OBJECT_0)
{
}
else
{
}
If you want to wait until the process is closed, then specify a timeout value in WaitForSingleObject. See this function for more details.

Use SHELLEXECUTEINFO with ShellExecuteEx() and the structure has a member "hProcess" this is the handle to newly created process.

HI.
I am running my application using command prompt.
like C:\> D:\App.exe
after launching this Application the command prompt come back to prompt again
like C:\>
does it means that application has been ended . but the appliccation is still running
then how can I come to know that application is still running using command prompt
thanks
Regards.

when you type : c:\ D:\App.exe and comes back to c:\
it will happen ...Here you are not changing the drive to access but just specifying the path of your exe.
Your exe will start as a new process ....so you have to eplicitly terminate your application

OK, Thanks.
But I have one more question that when we run Format command or some other command on Comand prompt, then why these comand are not run as new process. they usualy run in same command prompt and will not free the prompt until the command execution ends
Regards.

That is because those are Command-line applications. Back in the days of DOS, all applications were Command-line.
this is this.

if the application is Command prompt based then it runs fine...
but if it is windows based then application chooses the windows platform to run and application's info enters into windows enviornment not into DOS environment even it run from command prompt.
if you want to check the application running state then you have to check into running processes by enumarating processes or any other way.

Hi all,
I'd like to know, whether itz possible to send "Integers" and "arrays" through a RS-232 interface??is there any way to do it??
Thanks in advance,
rajeev

The RS232 interface is just that, a simple interface. How you send data depends on your protocol.

I believe it is possible, but you would have to send them over byte by byte, and then decoding them back to the original form at the other end. Actually much of the time, you would create an array of some data, either ASCII or Binary, but it takes the same way to send.
this is this.

Rs232 only understand Bytes.. so you have to interpret your Sending and receiving data!

On MouseMove event, how to capture a particular listitem? Basically, want to change the cursor on mouseMove on a specific column of the list control. Need to put a hand cursor on mousemove event. If the mouse is moved on a specific list item. only parameter in OnMouseMove is CPoint. Unable to get the subitem name.
Any clues please.
Thanks
Raji

Use the CListCtrl::SubItemHitTest() method to determine which item and subitem the mouse is over

I used the following code. But it does not take the correct column.
The part of code is in OnMouseMove event:
void CListt::OnMouseMove(UINT nFlags, CPoint point)
{
CPoint pt(point);
ScreenToClient(&pt);
LVHITTESTINFO hitInfo;
hitInfo.pt = point;
int nItem = -1;
nItem = m_list.SubItemHitTest(&hitInfo);
if (nItem >= 0)
{
m_list.SetItemState(nItem, LVIS_SELECTED, LVIS_SELECTED);
}
if (nItem >= 0 && hitInfo.iSubItem > 0)
{
int m_nSubItemHit = hitInfo.iSubItem;
if ( hitInfo.iSubItem == 8)
SetCursor(hCursor);
}
}
I need to change the cursor if subitem is "8". But even if move the mouse on the 8th subitem, the value of hitInfo.iSubItem is some thing else. moreover nItem is always -1.
Any clues please
Thanks
Raji

You don't need to call ScreenToClient() as the point is already in client coordinates when your message handler receives it.
