Hi..
a little bit difficult to write you back.. cause the interesting thing would´ve been HOW you tried to do this.. one thing that may help you is overriding the PreTranslateMessage virtual - function. (i hope your using MFC)
There you can handle all the events you would like to.. and if you return false the message gets routed down to CMainFrame (if you´re using the Doc / View Stuff...)
BOOL CDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->message == WM_KEYDOWN) //#256
if(pMsg->wParam == VK_ESCAPE) //#27
{
// do whatever you want to do if the user presses VK_ESCAPE
return true; //you´ve handled the message.. don´t route it any further
}
return CDialog::PreTranslateMessage(pMsg);
}
hope that i could help you with that...

Hi everybody
I found answer of my question myself. It was because of optimize for maxspeed
in release version that cause crash only on few computers and I turned off
optimize of a function that was insecure with #pragma optimize("",off) and now I
havn't any problem.

Hi,
I want to know, what is really CALLBACK ???
Is it function ?
What is performance ?
So, explain FULL about it ...
And if possible please write a example ...
Thanks.

CALLBACK is a typedef referring to the
__stdcall "function calling convention".
You can read a FULL explanation about __cdecl, __stdcall and __fastcall calling conventions in MSDN.

in addition to what gbo said i think you might mean "what the hell is it?" and so it is simply a function pointer you provide to various api and mfc functions that allows the os to call into your app when an event happens that you want to be notified ... it kinda is a alternative to getting a message posted to your app queue for some situations (timers etc)
as far as i know that is

it's just a define to __stdcall, which is what windows uses (generally).
WINAPI, APIENTRY, CALLBACK,... etc, are #defined in windef.h, you can
look in there to further see what other calling conventions windows
has defined for you.
__stdcall says to push function arguments on the stack from right
to left, then call the function.

Is obj file written on fortran.

May i have access to this file if..add it to vc rpoject..?
If yes how?
THX.

you can create lib and use as all other libs
(i never tried to add obj between lib files but from project settings\link\object-library modules naming has to be possible too)

How can I use timer functions in Win32?
I'm doing an alarm clock so I want to learn!

Hello, the codegurus around the world.;)
I'm not familiar with Win32 like C style code so much,
but this is my guess.
1) Use ::SetTimer API function.
2) Pick up WM_TIMER message at WinProc function.
3) Maybe wParam or lParam includes Timer ID.
Or someone helps this?
Have a nice day!

You should use a threaded timer. The windows timer messages are the lowest priority messages and cannot be relied on. There is no guarantee that they'll be processed on a busy system. There is a threaded timer class on CodeProject that I use all the time.

How do you open a unicode file, using the C++ standard library? So far, I can't see that this is possible (no Win32 API, or no wfopen()-just using plain C++ iostreams, how do you
open a unicode filename, say for eg., a Korean filename?).
Your help is much appreciated.
|
|
|
|

With the old C library, use _wfopen(). With the C++ library, use wostream/wistream/wiostream. With the Win32 API, use CreateFile(), but for this last one your app needs to either be built as Unicode, or call CreateFileW() directly. CreateFileW() will not work on Win 9x.

Hi there, Mike
Seems like there's a misunderstanding-while I agree (and am aware of) with _wfopen (used in C) and CreateFileW (Win32) I am still not sure how you would OPEN a unicode file NAME using the C++ library.
You see, the open member of all the streams you mentioned (wostream/wistream/wiostream) all take a char* pointer, NOT a wchar_t* thereby not allowing me to pass a wchar_t string.
Please let me know if you come across anything informative. Thanks for your help!
Cheers,
Shanker

CreateFileW() takes an LPCTSTR for the filename
that converts to unicode

Classic case of communication errors; let me make it clearer: how do I open a unicode file NAME using the C++ library? Like I said, I do NOT want to use the WIN32 or plain C functions. The question arises, because none of the functions that open a unicode file take a wchar_t pointer to the file name. They all take in a char*.
Hope this makes my question clear. Thanks for your efforts!

Ah, I understand now. Yeah, the basic_fstream and basic_filebuf classes don't accept wchar_t* filenames. A design flaw, I guess. If the STL code weren't such an impenetrable mess of garbage, I'd suggest deriving a class from basic_filebuf and basic_fstream that accepts wchar_t*.

Why - when I delete record in database (dbf-file) it was not deleting.
When i opnening the dbf-file by standart program (FOR VIEW DBF-FILES) then I can see that
record which was delete by my program (CRecordset::Delte) is absent- it's normal.
But when i run my program again I can see that that record present there ...
I was opened file in file_menager - (F4 - for editing) and seen that record which was delete
is inside file...(and size of file did't changing)
What must I do that delete record once and for all?
