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.

MFC/Win32 Printing - setting page/paper size ?

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().

Are you sure sStr is C:\ when you got error and also why you dont use of value return of SetCurrentDirectory?

Hi all,

I'nm trying to read the data in a UDL file, but I think it is binary(despite being readable in Notepad), and all my attempts to read one has failed, generally getting some gibberish such as "y;[" and a load of blank spaces.

Can anyone help me in this regards

Many Thanks
Regards,

Thanks for the response, I've tried it, but with this result:
memblock="y;["

Isn't a udl file in unicode ??

If so how would one do it ?

Thanks again ...

I could not find the specifications for ‘.udl’, but I saw no indication that it has to be Unicode (just statements like plain text). I would open it as plain text, Unicode, and binary with a hex editor and look at it closely. After that a little research should provide the answer.

Assuming this file is in UTF-16 encoded UNICODE, ie every character is a 16 bit word, Notepad may have put a header on the file to indicate this (despite it supposedly being plain text ). I would try opening it in notepad and then saving in a separate file with UTF-8 encoding. Ordinary text processing code should then be able to read it. If not you've got a binary file.
If you have to read the unmodified UDL file then you'll need to find the size of that header ( I think it's four bytes but I'm not sure ), skip over it and then read wide characters a wchar_t or WORD or short at a time from the file.

Nothing is exactly what it seems but everything with seems can be unpicked.

CPaintDC dc(this); // device context for painting

HBITMAP m_Bmap;
CRect rect;

CString path,m_ifilename1,m_ifilename2;

path=AfxGetApp()->m_pszHelpFilePath;

for(int i=1;i<=path.GetLength();i++)
{
if(path.Mid(i,18)=="VTS_VC_0003_070605")
{
path = path.Mid(0,i+18);
break;
}

}
m_ifilename1 = path + "\\"+"3.bmp";

GetClientRect(&rect);

m_Bmap=(HBITMAP)::LoadImage(NULL,m_ifilename1,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
memdc=::CreateCompatibleDC(dc.m_hDC);
::SelectObject(memdc,m_Bmap);

BitBlt(dc.m_hDC,0,0,rect.right,rect.bottom,memdc,0,0,SRCCOPY);

What's the source of the bitmap? A resource? A File? What type of bitmap?

Hi,
I have added functionality to add history in my list control by using the following function.
BOOL GetHistory(CStringList & list)
{
STATURL url;
CString strUrl;
ULONG uFetched;
IUrlHistoryStg2Ptr history;
IEnumSTATURLPtr enumPtr;

if(FAILED(CoCreateInstance(CLSID_CUrlHistory,
NULL,
CLSCTX_INPROC_SERVER,
IID_IUrlHistoryStg2,
( void**)&history)))
{
return false ;
}

if(FAILED(history->EnumUrls(&enumPtr)))
return false;

while(SUCCEEDED(enumPtr->Next(1,&url,&uFetched)))
{
if(uFetched==0)
break;
strUrl = url.pwcsUrl;
list.AddTail(strUrl);
}
return true;
}
Only IE history is added to my list control.How can i add history of other browsers also.

Do they store history data in the C:\Documents and Settings\<user>\Local Settings\History folder?
