is it illegal to develop and distribute gaming (lotteries) programs on the Internet?

i guess it is illegal because I can not find this kind of software on the Internet.

The legal nature depends on a number of different factors:

(*) Content of the software.
(*) Software Components and/or libraries that go into this software, whose redistributable and/or similar licensing clauses do apply.
(*) Internet Bandwidth requirements and restrictions do apply.
(*) Particular country's/region's legal restrictions do apply.

You always send a buffer therefore the function first parameter is const void* lpBuf.

the trick is to know what you are sending and be able to read it on the other side.
so if you know you need to send a variable, translate it to the buffer (using simple Format of CString for example) and on the other side read the buffer and do a simple number translation (_ttol for example)

hope this helps ya

I have had the handle of the thread that belong to another process.
but I find that you can get few infomation from the handle.
Now,I want get Which module the thread belong to?
And I knew A software , ProcessExplorer http://www.sysinternals.com[^], can do this.

You ask "which module the thread belong to?". This question doesn't really make sense - A thread can "weave" through multiple modules (and in general does).

I didn't use your link.
I think u can numerate all processes, and enumerate all threads of every process to find the thread you request.

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.

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.

m_nTimer = SetTimer(1, 100, NULL);

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.
