hi all,
i am having one problem with threading
i created one dialog based application whose work is to read the data from serial port and display it.so i created one thred for this work.
means now i got two threads one is application thread and other is serial communication thread which is created in OnInitDialog.
now everything is working i mean the thread got created it read some bytes
from port and now it wants to show the data so need to send this data to main
thread. so i am doing this with ::SendMessage() but it is giving access violation. i don't know why this is happening and currently i am not sending the data also i.e. buffer so please help me
below is code (stepwise)
1)In Oninitdialog
THREADPARAM *ptp = new THREADPARAM;
if(ptp)
{
memset(ptp->array,0,30);
strcpy(ptp->array,"Harshal");
ptp->appHandle = this->m_hWnd;
hSerialThread = CreateThread( NULL,
0,
(LPTHREAD_START_ROUTINE) SerialCommunication,
(LPVOID) NULL,
0,
&dwSerialThreadID);
}
2)Thread function
UINT SerialCommunication(LPVOID pParam)
{
int write_req=0;
THREADPARAM *ptp = (THREADPARAM *)pParam;
while(1)
{
if(write_req == 2)// send write request and read it
{
DWORD length=0;
DWORD dwRead=0;
if (WriteFile(hCom,
SEND_CMD, // pointer to data to write to file
NOOFBYTE, // number of bytes to write
&length, // pointer to number of bytes written
NULL) == 0)
{// write failed
write_req = 0;
continue;
}
// writefile succeeded issue readfile
char buffer[MAX_MESSAGE];
memset(buffer,0,MAX_MESSAGE);
if (!ReadFile(hCom, buffer, MAX_MESSAGE, &dwRead, NULL))
{
write_req = 0;
continue;
}
if(dwRead > 0)
{
//MessageBox(NULL,buffer,"Data with packet",MB_OK);
::SendMessage(ptp->appHandle,MY_SHOW_DATA,0,0);// error is here
}
write_req = 0;
}
else // only read from port and increment counter
{
DWORD dwRead=0;
char buffer[MAX_MESSAGE];
memset(buffer,0,MAX_MESSAGE);
if (!ReadFile(hCom, buffer, MAX_MESSAGE, &dwRead, NULL))
{
write_req++;
continue;
}
if(dwRead > 0)
{// you are in thread you need to send message to
// main application
//char a;
HWND hwnd = (HWND)AfxGetApp()->m_pMainWindow;
::SendMessage(ptp->appHandle,MY_SHOW_DATA,0,0);
//MessageBox(NULL,buffer,"Data without packet",MB_OK);
}
write_req++;
}
}
return 0;
}
3) Sent message function
LRESULT CReadDataDlg::OnShowDataMessage(UINT wParam, LONG lParam)
{
return 0;
}
4)the handle i am storing in appHandle is right or wrong?
Thanks and regards
Harshal

In my opinion, instead of
hSerialThread = CreateThread( ..., (LPVOID)NULL, ...);
you should try this:
hSerialThread = CreateThread( ..., (LPVOID)ptp, ...);
I hope it helps.

It is difficult to answer, you don't provide enough informations. What you could do, is start your debugger and then, when the program crashes, open the callstack to see from where in your code the problem is coming.

Did you happenped to the situation I described, It just is this situation,I search it in the internet, and find someone has happed to it, but no solution. I am confuse it,it assert in the constructor, I don't know how to deal with it.

Did you try AFX_MANAGE_STATE( AfxGetStaticModuleState());. This line should be added before calling any MFC related functions.

This may sound Stupip, but, How do I set up this Browser Applet, so that i can return to a forum object I either posed or answered to. At the Moment I have tpo browse tru dozens of pages of new messages generated in my absence, to find back my thread. Surely there must be a better way. While on the subject, I get notified by Automatic email of responses. The URL's Provided do not appear to work.

Hi all,
I seem to have lost my focus rect!  When tabbing to a CButton you would normally expect to see a focus rect drawn on the button. In my app it doesn't. When mousing to it I get the typical XP highlight around it, but the actual dotted line that should also be drawn is missing.
Any ideas?
P.S. Same thing happens to Checkboxes. (I know they are related
Thanks!
