Looks like it’s the symbol for the thread entry point. I had a brief look but couldn't see any easy way to get this info - It didn't seem to be in any of the well known fields of the TIB for example. You could examine the bottom of the threads stack I guess.

WNetAddConnection2()

Hi brothers

I have written one application. This will connect more than 200 machine at a time using WNetAddConnection2(). 75% of machine are connected successfully but rest of them not connected. Error message is ‘The net work path is not found’ (error no 53) . But I can connect manually OMG | :OMG:

. If I run the same program, the same machine which is not connected previously is connected this time. But only 75% of machines are connected. I use multithread for connection. Domain, login user and password are ok .

How can solve this problem. Confused | :confused:

Timers

Hi everyone,

I am trying to develop a Dialog based application for a device communicating through RS 232 serial Port. The serial port receives the new samples of data every 100 milli seconds. I am trying to display the message in a textbox and write the data to a file. For this purpose, i created a thread for receiving data. I am using a Timer with 100 milli seconds for Updating the textbox and writing the received data to the file.

The Problem now i am facing is, when the file gets full, i am trying to display error message and stop the timer. But Timer is not getting stopped by KillTimer().Timer continues in the running state.

BOOL MyDlg::OnInitDialog()
{
....
...
ConfigureSerialPort();
AfxBeginThread(Serial, NULL,THREAD_PRIORITY_NORMAL,0,0,NULL);
return TRUE;
}

void CMyDlg::OnClickStart()
{
fp = fopen(file_name,"a");
if (NULL == fp)
{
MessageBox ("Error Writing File",NULL, MB_OK|MB_ICONSTOP);
KillTimer(m_nTimer);
}
m_nTimer = SetTimer(1, 100, NULL);
fprintf(fp,"%d\n",status);
}

void CMyDlg::OnTimer(UINT nIDEvent)
{
OnClickStart();
CDialog::OnTimer(nIDEvent);
}

UINT Serial(LPVOID pParam)
{
while(1)
{
DWORD dwBytesTransferred;
ReadFile (hPort,
inbuf,
60,
&dwBytesTransferred,
NULL);
Sleep(100);
}
return TRUE;
}

Please help me regarding this problem. I am New to MultiThreading Concepts.

Thanks.

Chetan.

This is because you are setting the timer again in OnClickStart. Why are you doing this? You don't have to set it again and again as you are doing now.

Look at the lines in bold. You first Kill the timer and then again you set it. So how can you expect it to stop at all.

chetan210183 wrote:
void CMyDlg::OnTimer(UINT nIDEvent)
{
OnClickStart();
CDialog::OnTimer(nIDEvent);
}

Again inside the timer function you are calling OnClickStart which in turn again sets the timer.

What you should be doing is...

void CMyDlg::OnClickStart() 
{
   //set the timer here. Nothing else!
   m_nTimer = SetTimer(1, 100, NULL);
}

And now inside the timer function

void CMyDlg::OnTimer(UINT nIDEvent) 
{
   //write your timer related code here. Not anywhere else!
   fp = fopen(file_name,"a");
   if (NULL == fp)
   {
       MessageBox ("Error Writing File",NULL, MB_OK|MB_ICONSTOP);
       KillTimer(m_nTimer);
   }
}

Note: Well this is just guess work about what you want to do. You will have to modify the above procedure based on your requirements

Thanks for the Reply.
But without a messagebox, the code excecutes properly. When messageBox is inserted it is leading to infinite loop.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/timers/timerreference/timermessages/wm_timer.asp

In the above link, they have mentioned a statement like below.

"The WM_TIMER message is a low-priority message. The GetMessage and PeekMessage functions post this message only when no other higher-priority messages are in the thread's message queue. "

So instead of Timers , can i use threads and loop the function?

I mean replacing the Timers with Threads.

Thanks.

I don't know if this is what you are searching for. Here[^] is it. Well it has got some topics on which multithreading depends. Will make a good reading for you.

for killing timer use

KillTimer(1);

i.e what ID you provided to set the timer

The Timer returns the timer id when hwnd parameter of the settimer is NULL

hope this is enough for you

From MSDN:

Return value of SetTimer:

The timer identifier of the new timer if the function is successful. An application passes this value to the KillTimer member function to kill the timer. Nonzero if successful; otherwise 0.

You can mask the COM port, and wait for events happen in COM port and then only update the text box.

Use EnumWindows to enumerate all top level windows. For each window enumerated use the GetWindowThreadProcessId function to filter the windows to those belonging to the desired process.

There are a lot of hWnds in a top level window, such as Static, Button, EditBox etc. Using EnumWindow to look for hWnd wastes a lot of resources of system, and makes the system slowly.
Can anybody give me a good idea!! thanks.

EnumWindows only enumerates top level windows. The procedure I outlined doesn't waste system resources - It's how it's done!
