Do you ever release the mutexes you lock with WaitForSingleObject? Once you are done with it you should call ReleaseMutex[^]. Anyways, the high CPU usage can mean 2 things i think: you either make too many threads, or one or more of your threads are stuck in an infinite loop. Once your program is eating all the CPU power use your debugger to break execution and check what your threads are doing. If there are a lot of items you need to process you are probably better off using a few threads and queuing the items to them rather then creating a hundred-and-twenty-five threads for each and every item you want to process.

sorry, when i extrat my code i forget to change some words:
here is the right one and I have release the semaphore in each thread, right in front of "return", and I know the queuing policy is better but I just want to find out what's wrong with my program,by the way at the same time there can only be 10 threads because of my semaphore controling policy.see"//"
main(){
....Handle hCont=CreateFile(....);
hSema=CREATESemaphore(0,1,1,0);
hSemaThr=CREATEMUTEX(0,10,10,0);//so there are only 10 threads at most in the same time
WHILE(regex_search(begin,end,stringmatch,r)){
string s=stringmatch[0];
begin=stringmatch[0].second;
WaitForSingleObject(hSemaThr,INFINITE);
CreateThread(0,0,Grab,(void*)dc,0,0);
}
CloseHandle(hCont);
}
void Grab(void* doc){
......
......
WaitForSingleObject(hSema,INFINITE);
if(!WriteFile(::hCont,lpBuf,(int)strlen(lpBuf),&lpN,0)){
cout < <"can't write file in thread" < <GetLastError() < <endl;
//system("pause");
}
ReleaseSemaphore(hSema,1,0);
ReleaseSemaphore(hSemaThr,1,0);
return;
}

Please put your code posts between <pre> and </pre> tags for better readability next time.
Did you try breaking the execution to see what your threads are doing when they gabble up the CPU?

I'm gonna include a Task Panel (something like the time when you open the Search Window within the Windows Explorer). But I think a CView object _which normally fully occupies the frame window_ is not a good container to that panel (As It's intended to be Document Viewer). I'm solicited to RESIZE the View Window within the Frame Window to fit the panel; but I'm not sure if this is a wise thought or not...
Thank you masters!

If you're using VC++ 2008, you can get one of those for nowt in the MFC feature pack[^] lookup CMFCTasksPane[^] in the documentation.
Otherwise - is there something in here[^] that would suit?
If none of those are what you want, I'd suggest you find an MFC docking pane implementation and put your Task panel on a docking pane. Or add a splitter to give you two views (one of which could be a form view or something that you paint your task panel on.
I guess I'm basically agreeing with you - you should add a separate window for the pane, and NOT make it part of the view.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Do the same as this C code:
int a,b,c,d;
sscanf("1234", "%1d%1d%1d%1d", &a, &b, &c, &d);
|
|
|
|
|
This would print the digits in the reverse order. Now you can store the digits in an int array and print...
int a = 0 ;
int i = 1234;
while(i!=0)
{
a = i%10;
i = i/10;
cout << a;
}
You need to google first, if you have "It's urgent please" mentioned in your question.

cin - The object controls extractions from the standard input as a byte stream
so you can use it as well.

Yeah, istringstream is ok, but is there any format control mechanism for this?
|

You might look into istringstream and num_get(). I've not tried it, however.

I have ATL COM server and a dialog based application as a client..I need to test my server on a remote machine and access the method of the server from my local client... copied the exe of the server on the remote machine and I have used CoCreateInstanceEx to create a instance of the remote server..Should i Need to do anything else..Should I create proxy/stub for my application? If so ,how can build proxy/stub?Please help me out...
Thank U...

Thank u.. But then, Im not able to connect to the remote COM...What should be wrong then?
Thank u..

I don't know.
You should possibly post your calling code.BTW, what was the CoCreateInstanceEx return value?

This is my client code that calls the COM server on the remote machine...Thank u..
HRESULT hr;
IIGetFile2* pGetFile;
//
IUnknown* pUnknown = 0;
COSERVERINFO ServerInfo = {0,0,0,0};
wchar_t * remotemachine = L"servername";
ServerInfo.pwszName = remotemachine;
//MULTI_QI qi = {&__uuidof(IGetFile2),NULL,S_OK};
MULTI_QI qi={0,0,0};
qi.pIID = &IID_IUnknown;
//
IIGetFile2 * pInt = static_cast<IIGetFile2 *>(qi.pItf);
USES_CONVERSION;
CComPtr<IIGetFile2> Ptr1;
qi.pIID = &IID_IIGetFile2;
//
hr = CoCreateInstanceEx(CLSID_IGetFile2,NULL,CLSCTX_REMOTE_SERVER,&ServerInfo,1, &qi);
pUnknown = (IUnknown*)qi.pItf;
if(SUCCEEDED(hr))
{
AfxMessageBox("SUCCEEDED CoCreateEX");
}
pUnknown = (IUnknown*)qi.pItf;
hr = pUnknown->QueryInterface(IID_IIGetFile2, (void**)&pGetFile);
hr = pUnknown->Release();
if(SUCCEEDED(hr))
{
AfxMessageBox("SUCCEEDED QI");
_bstr_t bstrFileContent = pGetFile->GetFile2();
char* Text = _com_util::ConvertBSTRToString(bstrFileContent);
m_edit=Text;
UpdateData(FALSE);
}

Fine.
Is your server machine name "servername" (or simply is the name in your real code correct?
What about the hr (the CoCreateinstanceEx return value)?
And what about qi.hr value?

No, Its RDSServer ..I have given it correctly...
CoCreateinstanceEx hr=-2147023174
and for qi.hr I get access violation exception...

Your error code corrensponds to: "Error 0x800706ba - The RPC server is unavailable" see, for instance, this page [^] for some info.

Thank u...Let me try out...

Hi...I have another doubt..In case of testing both client and server on the local machine I have used this include statement...
#import "..\FileServer\FileServer.tlb"
using namespace FILESERVERLib;
But, When testing the server on the remote machine what kind of import statement Should I give..?
Thank u...
|
|
|
|

The import statement is used, on the client side, to build the client itself. It has nothing to with the testing phase (i.e. use always such statement to build the client and then forget about it...)

Thank u..So,u mean to say that it has nothing to do with my remote access...Right..

Hi.. I tried the code.. When I'm trying to create an instance on the remote machine I get ACCESS DENIED error.. I have the security permissions for the DCOM though..
Thank U...
