Since, it is a Windows Service, and I'm using MSVC6, I'm really unable to debug it.
When I call the Close method for CAsyncSocket class, the program crashes. So it seems that there is some problem in MFC's code.
|

If you are not able to attach a debugger to the process, how about a simulated stop of the service handler? Maybe write a mockup framework that would trigger your code under similar conditions. Just a guess, you are not using CAsyncSocket in multiple worker threads, everything is one thread context?

I call the function which is called when the SERVICE_CONTROL_STOP event is fired by myself. But I'm unable to reproduce that crash. It only occurs when it is stopped by Service Manager. No I'm not using CAsyncSocket in multiple threads

Hello,
How can i get the CPU information under VC++ (cpu modelname,cpu speed).
THNX for help!
|
|
|
|

this gives you some of the info - not sure if speed is in there ...
http://msdn.microsoft.com/en-us/library/hskdteyh(VS.80).aspx[^]
[edit]
this from gamedev shows some interesting things - Ive seen the same method for getting the speed used before ...

In vc++ got some error.
For example error C2653: 'ELog' : is not a class or namespace name.
I can't compile it.

Hi,
I'm working on a Windows Mobile application that connects to a server on a PC.
The problem with the following lines:
CSocket as;
if(!as.Create())
MessageBox(_T("creation failed"));
if(as.Connect(_T("192.168.1.24"), 110))
MessageBox(_T("connected"));
else
MessageBox(_T("failed to connect"));
is, that Connect(...) allways returns TRUE, even if the server isn't started and even if the PC with the IP address 192.168.1.24 is switched off.
This error only occures with Windows Mobile and a WLAN connection. On Windows XP/Vista connected via WLAN/LAN or Windows Mobile connected via USB Connect(...) returns FALSE when there's no server.
Any hints?
Thanks,
Thomas
ps.: to be a bit more precise - the problematic connection is from a PDA via WLAN to a Netgear internet router and the PC is connected via LAN

Hi everybody,
I like to catch the doubleclick on the MDI Frame.
Not somewhere into the Frame, rather on the titlebar of the frame itself.
In PreTranslateMessage of the MDIChildWnd I tried already to catch the message
WM_LBUTTONDBLCLK, but it seems that this message is never handled to this frame.
Has anyone an idea?
Big thanks 
|
|
|
|

Knowing how frames work for normal windows, I suspect you want to look for WM_NCLBUTTONDBLCLK, i.e. the non-client area equivalent of WM_LBUTTONDBLCLK

Hai!
Is there any key in the registry which changes its value each time i install and uninstall the driver for a smart card reader!!
Thanks!
|
|
|
|
|
There are many registry settings changing. What is the purpose of this question? Why do you need to know registry modifications?
There are too many to list and some are vendor specific. Locate the driver installation package for your smartcard device and open the INF file. Registry modifications are located in the 'AddReg' sections. You can also install an installation monitor and log the registry changes.
Best Wishes,
-David Delaune

Hallo,
I have the following problem with the Thread:
I create the Thread first as SUSPENDED, but it does not start at the expectetd time.
First the Program calls this function:
ThreadStart();
///////////////////////////////
ThreadStart()
{
if (m_pSelThread != NULL)
{
if (::WaitForSingleObject(m_pSelThread->m_hThread, 0) != WAIT_OBJECT_0)
return;
delete m_pSelThread;
m_pSelThread = NULL;
}
::WaitForSingleObject(m_SEl_Start_Event, 0);
m_SEl_Start_Event.SetEvent (); // CEvent Object
CWinThread* m_pSelThread = AfxBeginThread(ThreadFunktion, this, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED);
m_pSelThread->m_bAutoDelete = FALSE;
m_pSelThread->ResumeThread();
}
UINT ThreadFunktion
(
LPVOID param
)
{
if (param == NULL)
return -1;
DoSomeThing();
return 0;
}
The Thread does not come to the UINT ThreadFunktion(LPVOID param).
Any help would be appriciated.

Shouldn't that be:
m_pSelThread = AfxBeginThread(ThreadFunktion, this, THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED);
i.e. you're hiding the class member variable with the local one.

to wait for the event to happen.

That doesn't make sense. Anyway I made a test on my system:
Without hiding the class member variable, the thread starts happily.

Can't you just start the thread and wait for the event to happen within the thread before executing code? What's all this mess about? Why are you setting the m_bAutoDelete member to false? I see you may delete it manually, but *what* is the purpose of it?

the thread mus t be created but not start immediately, autodelte false to tell him not to delet himself.
|
|
|
|
|
So, why should it not start immediately? Can't you just start it immediately, but not execute any code until the interested event happens? I asked for the reason behind your approach. I did not ask you what m_bAutoDelete is for. Tell me why do *you* want the thread not to delete itself.

Well you may want to do that, I mean that's nothing wrong in doing it (and that's the reason for delaying the thread start).

No, I asked why did he want to delete it manually (as opposed to leave it die in its way). There could be valid reasons, I wanted to know the OP's reason.

You're right: there could be valid reasons, anyway you're very (and, of course, politely) curious about her reason.
