#pragma can remove warning from Output window, but find the cause and solving if possible could be better.

Oh, you cannot. And you don't need to worry about: the warning simply states that the identifiers will be truncated in the debug info. But this is inavoidable since there is a 255-characters limit for identifiers in debug information and, on the other hand, STL templates produce very long identifiers. Bottom line you can safely ignore that warnings.

thanks for your replys...
now my problem is i have made various ui threads before starting these thread i have checked using this code whether they are running or not..

std::map<int, CSmtpThread*>::iterator pos = assocs_Smtp.find(l);
if(pos == assocs_Smtp.end())
{
   StartingSmtpThread(URL,l,total_timeinterval,prt,Task_Nm);
}
				}

and i have closed my thread using this code

std::map<int, CSmtpThread*>::iterator pos = assocs_Smtp.find(smtpkey);
if(pos != assocs_Smtp.end())
{
	CSmtpThread* pThread = pos->second;
	pThread->PostThreadMessage(WM_QUIT,NULL,NULL);
}

once i start thread it works fine, when i stop it try to start it it doen't work.It doesn't go inside if condition...

how to solve this problem...

Because (as far as I can guess...), once you stopped the thread, you have to remove it from the map.

Thanks this solved my problem....

now one more problem i m having that when these ui threads give me result i send the output to my main window to print it in my list control using SendMessage. like this

if (m_pLogWnd)
{
	pasiin_val obj_val;
	obj_val.index = test_int;
	obj_val.url = test_str;
	obj_val.task_n = test_task_name;
	m_pLogWnd->SendMessage(LOGMSG, (WPARAM)(CString*)&logmsg, (LPARAM)(&obj_val));
}

m_pLogWnd is been assigned with this of my main window...

now my first problem is when i start and stop my thread various times it gives abort assertion failed error sometimes in wincore.cpp in line 980 and sometimes in afxwin2.inl and it sometimes also say that refrenced memory cannot be accessed..

and second after stopping my thread in some threads it shows output value...

how to resolve it...

Oh I see, Thanks for your help and explanation!!
Other than code, there is one more option to disable the warning:
In Project Menu --> Project Properties --> C/C++ --> Advanced --> Disable Specific Warnings, we can specify a warning number to be suppressed as follows:

/wdn

Disables the specified compiler warning where n is the compiler warning number.
For example,

/wd4786

disables compiler warning C4786.

You're welcome.

Well, I don't disable warnings: they make me feel less alone Big Grin | :-D

Well - I know this feeling:

Hi!! You're not alone!! Me too never disable but solve warnings only if it is necessary.

To print data from my CFormView, I am using MFC Print architecture (OnPreparePrinting, OnBeginPrinting, OnEndPrinting etc.) . OnPrint manages printing (and OnDraw for screen). On Dot-matrix printer, need to print 3 or 4 text-invoices one by one (one below another), on one A4 size paper (data is from CFormView).

How/Where to set paper size (height) to say 2.55 inches, so that I can print single invoice without ejecting A4 paper (on Dot-Matrix printer).

If possible, I wish to use MFC Doc-View Print architecture otherwise Win32 printing.

Please help me with some code-snippet.
Thanks for any help

The following is a code snippet for checking the subdirectories.
This code is crashing in the highligted line when sStr is "C:\".If it is "D:\" or "E:" it is working.

void CBatchPrintDlg::ChkForSubDir( CString sStr, HTREEITEM hTree )
{
struct _finddata_t c_file;
long hFile;

::SetCurrentDirectory((LPCTSTR)sStr);

if( (hFile = _findfirst( "*.*", &c_file )) != -1L )
{
if ( IsDirectory ( c_file.attrib ) )
InsertItemTOTree( (LPCTSTR)c_file.name, hTree );
//m_tree.InsertItem((LPCTSTR)c_file.name, hTree );

while( _findnext( hFile, &c_file ) == 0 ) Confused | :confused:

{
if ( IsDirectory ( c_file.attrib ) )
{
InsertItemTOTree( (LPCTSTR)c_file.name, hTree );
//m_tree.InsertItem((LPCTSTR)c_file.name, hTree );
//break;
}
}
_findclose( hFile );
}
}

Please help.

Thanks.

Since you are using MFC, why not utilize CFileFind? It's much cleaner. What exactly is your code supposed to be doing? There's no need to call SetCurrentDirectory().
