Programatically:
When you create the process, store the handler. You can then later check handler after handler if the process is still running.
Physically:
Hit Ctrl+Shift+Esc, go to process tab, and check if your processes are still alive.

Perhaps something like this:
bool HasProcessExited(HANDLE hProcess)
{
return WaitForSingleObject(hProcess, 0)==WAIT_OBJECT_0;
}

I am not totally clear on what you are experiencing. But here's some thoughts.
1. Don't wait inside a windows message handler. If you block for an extended period inside the message handling thread -- you could be seen as "not responding".
2. Use a reasonably short timeout on your wait. You can always wait twice.
3. Make sure you are using the correct handle in your Wait() call. How are you getting this process handle?

"How are you getting this process handle?"
CreateProcessA(NULL, CmdLine, NULL, NULL,<br />
FALSE, dwCreationFlags, NULL,<br />
NULL, &si, &pi)
sow I get this handle 'pi.hProcess'.
thanks.

Hello,
I'm trying to catch mouse buttons (5) via the XBUTTONS and would like to do this in an MFC environment. I have seen some examples in Win32, but not MFC.
I have declared the following in the CMainFrame message map
ON_MESSAGE(WM_APPCOMMAND, OnAppCommand)
then try to process it within the function...
LRESULT CMainFrame::OnAppCommand(WPARAM wParam, LPARAM lParam),
...but this function never gets called.
Any help greatly appreciated.
Cheers,
Grant.

Maybe you need to put it into the CView class instead.
Maybe the message does not make it to the mainframe.

Hi Everybody!
I am currently trying to build an application for videoconferencing between 2 computers using Wifi.
Since I have already began to program some functionnality with directshow, I was wondering if it there was any existing directshow filter for broadcasting audio and video streams.
Actually, I am looking for a directshow filter on which it's possible to connect an audio source filter and a video source filter on it.
Thanks a lot for your help!

Maybe 3rd-party, but there's not a filter included with DirectShow.
The Windows Media Format SDK has a network writer sink for broadcasting ASF format media.

Hi Thanks for the answer.
Do you know if windows media format SDK is compatible with Directshow connectivity. I mean : Can I connect my Directshow source filter directly to it.

Not directly. It takes a little work but less work than writing your own streaming code.
With Windows Media Format, you basically configure a profile for the streams, pass uncompressed
samples, and it does the rest.
The trick is to get those samples from DirectShow. One easy way is with the grabber filter.
Another harder way is to write a custom filter.
Download Windows Media Format 9 Seres SDK[^]
The WMF network reader/writer does not use RTP AFAIK. It does use HTTP protocol for easy
firewall traversal.
There may be 3rd-party DirectShow filters to do it as well.

Hello all,
I'm trying to use Microsoft Win32 Detours library (API interception library). Because it is a production of their research lab, they offer no formal support.
At the beginning I had problems compiling the latest version (version 2.1) of the library with MS C++ Express - however, it compiles fine on VS2003.
When compiling the DLL which contains the custom functions (the detour DLL) I get the errors:
<br />
detours.lib(detoured.obj) : error LNK2005: _DllMain@12 already defined in testC.obj<br />
LINK : warning LNK4098: defaultlib 'LIBC' conflicts with use of other libs; use /NODEFAULTLIB:library<br />
Release/testC.dll : fatal error LNK1169: one or more multiply defined symbols found<br />
I did try to use /FORCE:MULTIPLE, which caused a successful compilation. However, when I load the DLL using one of the destours samples (withdll.exe) I get the error:
<br />
Error: testC.dll does not export function with ordinal #1.<br />
I know that this is a library specific question and this forum is for C++ general discussion. However, I have no other place to ask. I was also hoping that I can get an answer since this *looks* like a settings problem.
I did use an older version of Detours library a long time ago and I had no problems.
Detours website: http://research.microsoft.com/sn/detours/
Many thanks in advance,
- Naimi
SOLVED
I did not use a .def file which exports the functions (I did not need to do this with Detours version 1.5)

I develope applications which are mostly standalone Desktop applications. Few applications are of GDI+ and few serial ommunications applications.
If i wanna upgrade from VC6.0 to VS2005
Should i buy Professional Edition which is $799.00
or i would go for Standard edition which is $299.00
Will my applications work properly in standard edition mostly i am worried about GDI+ applications.
Thanks,
Sandip.

they will work fine in both, the editions are not limited by technology, except the express one. They are limited by other features. There would be a feature matrix on the MS site, I am sure.

Ya i went through the Features set i didnt understand few things from there so i was confused.
Will there be much migration issues??.
Thanks,

If there are any, they will be the same for both Professional and Standard.

Hi,
I have a listbox containing strings items. When the user selects an item in the listbox using keyboard character, there is a vertical cursor/caret displayed at the end of first character. E.g. If the listbox has String items as "One", "Two", "Three", "Four", "Five", "Six", "Seven" etc... and the user press character "s/S" after bringing the focus on the listbox, a vertical line similar to the one shown in the following word "S|ix" is dispalyed.
Basically a veritical line is shown after the first character of the item if it exists in the listbox
How do I get rid of this cursor? I have tried using "HideCaret", SetCaretPos API in selectchange message handler, onfocus message handler but the vertical line is still vistible, though it goes away automatically in a second or two, I do not want it to be displayed at anytime.
Thanks.

What does the code look like that creates the control?

Hi Mark,
It is a standard code generated with VC++ 2005. I had simply created a dialog based application. Added a listbox to the dialog and added the code in the InitDialog method to insert the strings in the listbox. When I compile and execute the application the dilaog comes up with the listbox and strings in it, nothing special other than this. Anyways you can see the InitDialog code below where the list box is initialized with strings
CListBoxDialog::OnInitDialog()
{
CDialog::OnInitDialog();
// Other code add by the wizard....
// my code
const TCHAR* Strings[10] = {_T("One"),
_T("Two"),
_T("Three"),
_T("Four"),
_T("Five"),
_T("Six"),
_T("Seven"),
_T("Eight"),
_T("Nine"),
_T("Ten") };
for(int i = 0; i < 10; i ++)
{
m_List.AddString(Strings[i]);
}
return TRUE; // return TRUE unless you set the focus to a control
I didn't made any changes in the properties of the listbox.
Thanks
}

Thanks! Can you post the code from the resource (rc) file for the dialog resource?
That's where the control styles are.
I'm curious because I can't get a caret to appear in a listbox.
