file descriptor returned by api's like _open();
pther wrote: How to use _commit(int fd)?
int fd = _open( "sample.txt", _O_RDWR);
... write something to file.
_commit(fd);
"The _commit function forces the operating system to write the file associated with fd to disk. This call ensures that the specified file is flushed immediately, not at the operating system's discretion." from msdn;

[add] are you looking for CRichEditCtrl::LimitText[^]? [/add]

Handle the WM_PASTE command and covert the font size to required size.

i am using SendMessage(WM_PASTE,(WPARAM)0,(LPARAM)0); command but my issue is how i set the font size.

It doesn't matter how the text is being pasted. You just need to add an appropriate handler to your control and write your code to format the text there.

I am using the appropriate handler but i dont find any message handler to set the size .EM_SETFONTSIZE doesnt work "error C2065: 'EM_SETFONTSIZE' : undeclared identifier"
Do you have any clue.

You should find the handler of the rich edit control for the PASTE message, and then use the member function(s) of the rich edit control with which you could do formatting.

Have you tried handling WM_PASTE for your control? Have a look at the members[^] of CRichEditCtrl, which may help you to set the format of the text which is being pasted.

try handlling CRichEditCtrl::Paste , there you could manipulate data before actually putting on editcontrol

Hey Shilpi,
I'm fiddling between two different machines (on my development machine, the internet is temporarily not working). You could use SetDefaultCharFormat[^] to set the default character format of your rich edit control. Any text entered would be according to the format you've specified with this call.

ADD L before string
HRSRC hResLoad = FindResource(AfxGetResourceHandle(),MAKEINTRESOURCE(IDR_IDR_EXE_EXEEXTRACTOR),L"IDR_EXE");

I have one more problem....
CString m_FName;
LPCSTR data = (LPCSTR)LockResource(hResData);
CString strFName = m_FName + data;
third line gives error
error C2679: binary '+' : no operator found which takes a right-hand operand of type 'LPCSTR' (or there is no acceptable conversion)
how to convert LPCSTR to CString

does the resource contains unicode string.

CString constructor will take care of that!

my question is still valid, "does the resource contains unicode string. "
ThatsAlok wrote: CString constructor will take care of that!
it will take the ANSI string CString(LPCSTR) and converts to Wide char. what happens if the resource is already a wide char string.
as OP already said resource contains wide char [^],
then
LPCSTR data = (LPCSTR)LockResource(hResData); it is wrong cast.
the solution can be
LPCTSTR data = (LPCTSTR)LockResource(hResData);
CString strFName = m_FName + data;
or specifically,
LPCWSTR data = (LPCWSTR)LockResource(hResData);
CString strFName = m_FName + data;
I agree if the resource string not wide char, your solution is ok.

if you see, end result is going into CString,so it will take care by itself, since in starting where i replied her, about usage of L, there i become aware that she is working with wide character. so i suggested that solution!
your concern is also stand good, if it ansi app, then it could present problem.
thanks for good discussion!

what, i am taking about unicode app only,
LPCSTR data = (LPCSTR)LockResource(hResData); is wrong cast.
and CString (data) will internally call MultiByteToWideChar(); and is because of the wrong type cast.
if still didn't get, in a unicode app, try the following.
LPCWSTR resource = L"Wide Char Resource String";
LPCSTR data = (LPCSTR)(void *)resource;
CString str(data);
ThatsAlok wrote: i become aware that she is working with wide character
you didn't direct correctly even you already aware.
And also unicode app doesnot restrict a custom resource as ANSI string, this is not a invalid guess as OP is using lockResource, and not LoadString().

There might be some misunderstanding, since you couldnot add char* to CString , as it doesn't have overloaded + operator . thats why i suggested use of CString to nullify that effect!..
