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.

Use the STM_SETIMAGE message. See the MSDN documentation for more information.

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

HBITMAP m_Bmap;
CRect rect;
HDC memdc;

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?

What does DISCARDABLE in .rc file signify?

Why? Just visit some benign site that IE has not been used for, and then search for filenames, file contents, and registry entries for part of the URL.

Hi,

I created a Dialog based application "Sample" using VC 6.0 using the Wizard.
When I opened the resource file namely Sample.rc using a text editor,
I found

IDD_ABOUTBOX DIALOG DISCARDABLE 0, 0, 235, 55
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU.

What is the significance of the word DISCARDABLE above.
I removed the word and on compiling and running the application, could not
find any noticable change in any style.
MSDN was of no much help either.
