Are you wanting something like this?

Guys,I know this question has been asked ad-nausem, but I have the exact opposite problem. My release build works fine, my debug build does not !
I have an application that starts a whole lot of threads for processing multiple feeds of video and audio. In my release build all threads start successfully, but in my debug build some threads fail to start, AfxBeginThread returns NULL and GetLastError return 0.
I am assuming that some or other resource has to be increased for my debug build to work. I've increased my stack sizes (in project properties) to 10x what it was without making a difference. What other properties/resources can I try to set for my debug build to work ? Any other reason why some of my threads won't start in debug build ?

Hm, I had that problem two weeks ago.
Solution was simple in my case (well, after almost despairing), in project properties the debug and release version had provided different arguments to the main function.

Hi Souldrift,
Where in the project properties would I see that ? I looked through all the settings, but could not quite see where you can pass arguments to main.

Well, the problem here is, I got the german version. But I try to translate.
When I open the project properties there´s on the left side a box where I can find
* General properties
* Framework etc ...
* Configuration properties
* General
* Debugging <--
* C/C++
* etc.
You can find it under Configuration properties->Debugging. In the right window you can now see the arguments in the second line.
But then again, if you don´t know this property, then you most like didn´t enter anything in into it, anyway. You can use this to 'simulate' (argc, argv) arguments of a main function .. if your project has one. And as for everything else, you can do this seperately for Release and Debug version.

Thanks, but as you expected I have no arguments specified there !

First of all, sorry for my bad english.. I need help with my c code..
void Calculate()
{
for (int i=0;i<1;i++)
{
for(int j=0;j<3;j++)
{
c[i][j] = x[i][j] * w[i][j];
sum1 += c[i][j];
printf("Output[%d]: %.1f ",i+1,c[i][j]);
}
printf("\n");
printf("Sum: %.1f\n",sum1);
}
printf("\n");
for (int i=1;i<2;i++)
{
for(int j=0;j<3;j++)
{
c[i][j] = x[i][j] * w[i][j];
sum2 += c[i][j];
printf("Output[%d]: %.1f ",i+1,c[i][j]);
}
printf("\n");
printf("Sum: %.1f\n",sum2);
}
printf("\n");
for (int i=2;i<3;i++)
{
for(int j=0;j<3;j++)
{
c[i][j] = x[i][j] * w[i][j];
sum3 += c[i][j];
printf("Output[%d]: %.1f ",i+1,c[i][j]);
}
printf("\n");
printf("Sum: %.1f\n",sum3);
}
printf("\n");
for (int i=3;i<4;i++)
{
for(int j=0;j<3;j++)
{
c[i][j] = x[i][j] * w[i][j];
sum4 += c[i][j];
printf("Output[%d]: %.1f ",i+1,c[i][j]);
}
printf("\n");
printf("Sum: %.1f\n",sum4);
}
printf("\n");
}
how can i make this code become simple? its a sum of each row.. it has 4 row, sum1 is the sum for the first row only.. and sum2 is the sum for the second row only and so on.. please help me on how to make this code simpler cause i think its redundant.. thanx..

Hi,
not sure since you didn't show all declarations, but this should come close:
int sums[4];
for (int i=0; i<4; i++) {
sums[i]=0;
for(int j=0; j<3; j++) {
c[i][j] = x[i][j] * w[i][j];
sums[i] += c[i][j];
printf("Output[%d]: %.1f ",i+1,c[i][j]);
}
printf("\n");
printf("Sum: %.1f\n",sums[i]);
}

Hi all,
i am using this smart pointer to send http request to server:-
IServerXMLHTTPRequest2Ptr pIXMLHTTPRequest = NULL;
Then through this I called the method setproxy where second parameter is having some ip address:-
pIXMLHTTPRequest->setProxy(SXH_PROXY_SET_DIRECT,varProxyName,L"");
but this is causing exception and getlasterror() is returning "3".Please rovide some suggestions.
Thanks A Ton

When you call setProxy() have you already acquired a pointer to an object implementing the IServerXMLHTTPRequest2 interface? Have you properly set up varProxyName?

Hi Bacon,
First of all thanks for the reply....i have posted it three times but i get first reply so thanks.
i have used pointer of the interface like this:
IServerXMLHTTPRequest2Ptr pIXMLHTTPRequest = NULL;
and called the method setproxy on the same:-
pIXMLHTTPRequest->setProxy(SXH_PROXY_SET_PROXY,varProxyName);
where varProxyName = SysAllocString(L"114.127.246.36:8080");
when you sya...."have you already acquired a pointer to an object implementing the IServerXMLHTTPRequest2 interface"
so can you explain it in detail.or if you can provide some example for set proxy then it would be really helpful, because i didnt get anything useful in google....
Thanks A Ton

When you assign NULL to pIXMLHTTPRequest this tells it to point to nothing. You have to get an object of type IServerXMLHTTPRequest2 and assign it to pIXMLHTTPRequest before you can use it.

I haven't used IServerXMLHTTPRequest but it's a COM based object so you'll need to call CoCreateInstance() at some point. If you're not familiar with COM I suggest reading one of the introductions here on CP.

hi Bacon,
Please see the code:
HRESULT hresult = CoInitialize(NULL);
IServerXMLHTTPRequest2Ptr pIXMLHTTPRequest = NULL;
hr=pIXMLHTTPRequest.CreateInstance("Msxml2.ServerXMLHTTP.4.0");
that i have done.....please suggest if i am missing something.
Thanks A Ton

Hello,
i tried it the way you said, but it did not work , maybe i did something wrong, hier is the code:
void CTestView::ThreadStart(CTestDoc* pDoc, CString strSel)
{
m_Thread_Sel_Start.SetEvent ();
HWND hWnd = GetSafeHwnd();
m_strSelect = strSel;
m_pDoc = pDoc;// i need to access the CTestDoc.cpp, i passed pDoc from the CTestDoc.cpp to the CTestView.cpp
// and then assigend pDoc to m_pDoc which defined in the top of the CTestView.cpp
AfxBeginThread(ThreadProc, this/*hWnd*/, THREAD_PRIORITY_NORMAL);// Hier i passed this to the ThreadProc function
}
UINT ThreadProc
(
LPVOID param
)
{
(CTestView*)param-> // casting to CTestView did not work?
return 0;
}

okoay but i have an application crash hier:
#ifdef _DEBUG
void CTestView::AssertValid() const
{
CView::AssertValid(); // application crash
}
#ifndef _WIN32_WCE
void CTestView::Dump(CDumpContext& dc) const
{
CView::Dump(dc);
}
#endif
#endif

Is there a question here that I'm failing to see?

The question is when i pass (this) instead of (hwnd) to the ThreadProc function i get a crash. The question is above.

How about formatting your code correctly AND using the <pre> tag?

-> has higher precedence than a cast, you need parens around the cast so it's evaluated first:
((CTestView*) param)->SomeMethod();

HI all,
I am working on Non Overlapped serial I/O application.
I have only one thread to receive the data.For send i dont have any thread.
I just call Write file when i need to send .
My problem is, When I have my receive thread wait for an event using WaitCommEvent, it ties up the serial port. Then my sending function can't access the port with WriteFile. I knew waiting for a comm event would block the receiving thread but didn't expect that it would block use of the port.
Any suggestions on how to do non-overlapped communication, where the send fucntion can write while the receive thread waits for a comm event?
Regards,
Sunil Kumar

Try to open the port twice using CreateFile.
Use one handle for writing and another for reading from the port.
