NOPE
BTW do you seek information on the exported methods from the dll?

You could use a decompiler like Reflector[^] if the binary was built with managed code (and wasn't obfuscated[^]).

With a Win32 DLL, well, good luck.

You need to probably restructure your problem. First: Do you really need to display 1 lac lines in the list box...
I don't really think that any user for your application would be really interested in reading or going through that many lines of text at a time.
If not can you use some kind of paging mechanism rather than reading the whole file. Only read the number of records that you can display at a time.

You need to google first, if you have "It's urgent please" mentioned in your question.

this following piece of code is used in win32 programming.
this plays a vital role in servicing the messages.

CODE IS::

while (GetMessage (&msg, NULL, 0, 0)) {
TranslateMessage ( &msg );
DispatchMessage ( &msg );
}

i want to know how is it translating messages actually? (from which format to which format?)

thanks.

The role of TranslateMessage is to generate more "high lavel" messages from the "low level" ones that come directly from the input.

The typical case is WM_KEYDOWN/WM_KEYUP that, if observed for certain keys and shifts, generates WM_CHAR and WM_UNICHAR.

All new messages are re-posted on the same message queue, and hence fetched from GetMessage tehmselves.

I've tried your code in Microsoft Visual C++ 6.0 in an ANSI system and it seems to work properly. That is, it first displays "ABC" and then "BCD".

Use a thread, don't do everything on the main thread. When you do some time consuming task on the main thread the result is more like what you are facing right now.

Hi All,
I am stucked in a problem. I need to jump at a file's MFT record. Is there any way or API which can tell me the logical cluster number of a File's matadata location. I have to read the files data run which is in the MFT. FSCTL_GET_RETRIEVAL_POINTERS gives me the data run as well as the extends , but it doesnt provide the LCN of that location.

Is there any method which can provide me the LCN of a metadata file(MFT)of any particular file. Frown | :(

Thanks in advance.

Is it a single line edit control?
Check if you can set the multi line property of the edit control to true and the want return property as well to true.
