Your main thread is blocking on the WaitCommEvent.
Typically, code like this would be placed into a separate tread where it would not interfere with the processing of other information, such as mouse movements, painting, keyboard events, etc.

Hi,

Did you mean how to select Items from the list box?

Use CListBox::GetSel function to select the current item in the list box. If you want get all the item selected from list box, you get the total number of counts use GetCount function and check all the items is whether select or not

nope..what i meant is that after selecting the particular name in the listbox, i would like open the corresponding application that coincides with the name...

i used enumwin() to get the running application process and store its name to the listbox...but how can i show the window that corresponds to the application name selected?

While Enumeration of Window Store the Name of Window along with corresponding HWND or HANDLE.
when User select the Window to close just search the your local array for handle and send Close Message.

Hope you understand this

Thanks!but can i have a sample code of the array...here's how i stored the values
::enumwndfn(CWnd * wnd)
{CString s;
wnd->GetWindowText(s);
m_TaskList.AddString(s);
}

Bool CALLBACK CDlg::enumwndfn(HWND hWnd, LPARAM lParam)
{
CDlg* me = (CDlg *)lParam;
return me->enumwndfn(CWnd::FromHandle(hWnd));
}

called by : EnumWindows(enumwndfn, (LPARAM)this);

Thanks!

Do this thing

I think you m_TaskList is type CStringArray change it to CPtrArray.

and Create a Struct

struct MyArry
{
CString WindowName;
CWnd Wnd;
};

and Instead

spiced wrote:
::enumwndfn(CWnd * wnd)
{CString s;
wnd->GetWindowText(s);
m_TaskList.AddString(s);
}

use this thing

::enumwndfn(CWnd * wnd)
{
 CString s;
//get Window name
 wnd->GetWindowText(s); 

//declare Variable of MyArry
 MyArry tmp;
//Store Window name
 tmp.WindowName=s;
 tmp.Wnd=*wnd;

//Store it in Array
 m_TaskList.add(tmp);

}

Application fails in Release mode....

Hi,

I developed an application in VC++, and it is crashing in the release mode.I enabled Debbuging in the release mode, and I hv attached the dump of my Call Stack.

I dont know, why CWinApp object is NULL.Can anybody pl. help me in solving this...

TBMS3! __sbh_free_block + 369 bytes
TBMS3! free + 35 bytes
operator delete(void * 0x0145c030) line 349 + 9 bytes
CPlex::FreeDataChain(CPlex * const 0x00000000) line 45 + 6 bytes
CMapPtrToPtr::RemoveAll(CMapPtrToPtr * const 0x00000000 {CMapPtrToPtr}) line 94
CHandleMap::DeleteTemp(CHandleMap * const 0x00000000) line 239 + 8 bytes
AfxUnlockTempMaps(int 1) line 50
CWinThread::OnIdle(CWinThread * const 0x00000000 {CWinThread h=??? proc=???}, long 5120804) line 591
CWinApp::OnIdle(CWinApp * const 0x00000000 {CWinApp ???}, long) line 494

Also, earlier it was giving errors related to vector destructor iterator.
Wherever I used delete [] ptr, the application was failing. Even though I am not using delete [] from within my code, the MFC framework is using that a lot. Is there any way by which I can force the compiler to include vector destructor, and scalar destructor.

I am working in VC++ 6.0

Hello everybody!

First of all, thanks for your answer Blake Miller!!!

I didn´t explain the situation correctly.
I mixed up with the example!!
Sigh | :sigh:

I´ll try to explain it correctly...

I´m using CreateProcess to create a new process, with the
CREATE_NEW_PROCESS_GROUP flag set in the argument "dwCreationFlags",
to create a new process group.

Let´s suppose that PROCESS_A creates a new process,
with CREATE_NEW_PROCESS_GROUP flag set. This new created
process (PROCESS_B) is the 1º process of the process group.

It´s true that both the 1º process of a process group and
the process group itself have the same ID. So the ID of
the process group and the PID of PROCESS_B are the same.

If the PROCESS_B creates a new process (PROCESS_C) with
CREATE_NEW_PROCESS_GROUP flag cleared, both PROCESS_B
and PROCESS_C will belong to the same group.

PROCESS_B knows the ID of its process group, as it´s
its own PID. But...

-How can PROCESS_C get the process group ID?
(without using IPC or passing it through command line
arguments)

-Is there any function which returns the process group ID
of the calling process?

Summing up...
I only what to know how to get the ID of the process
group, to which a process belongs.

Thanks and bye.

Hi,
You may use ASPI or SPTI to read CD sector.
Scan TOC to locate specific folder descriptor ( see ISO 9660 ).
To send ASPI command you may use "SendASPI32Command" function from winaspi.dll, or use DeviceIOControl to send SPTI command.

It would be helpful if you could determine if none of the fonts work, or just the UrduPhonetic font. That would go a long way in isolating the problem to the code or the font. Is this a proprietary font, or one that can be freely downloaded?

Revision Control System and Tools

Hello all,

although this question is not related to the forum's specifics, I'd like to ask it here because I hope to get some answers from users of a Revision Control System.

I need to switch from Visual Source Safe to a Revision Control System which allows me to:
1. access projects over the Internet
2. have tools to integrate Visual Studio 6 and Visual Studio .NET
3. have additional tools to allow me to maintain todo's / work progress and to create version-based reports of my team's work

For the first two needs, after a quick search, I've found that a Subversion server with it's plug'ins might do the job.

So, my questions are:

- is Subversion good enough or are there better alternatives?
- which SCC provider should I choose: Subway, SourceCross or AnkhSVN? AnkhSVN is only for Visual Studio .NET, so if I choose it I'll also need one of the first two for Visual Studio 6.
- are there any Visual Studio-integrated tools which work with Subversion to help me maintain the list of todo's / work progress and any external tools to allow me to crete version-based reports (something like:
v1.0
Bug #1 - Bug description - Status: Fixed
New Feature #1 - Feature description
etc.

Thanks.

Regards,
George Ionescu
