Hi,Nibu
Here is what i want to...

first,make each MDIChildFrame show in the client of MainFrame with maxsize.next time when i switch between the childframes,they should also show with maxzize.

second,I wish to disable the maximize button minimize button on the child frame,but the close button should be usable.

any one who know please tell me.
Waiting for your reply.Thanks!

Add a message map entry for ON_WM_CHILDACTIVATE.

Override OnActivate(int nCmdShow);

Call ShowWindow inside OnActivate

eg: ShowWindow(SW_MAXIMIZE);

Override PreCreateWindow and add this line

cs.style &= ~WS_SYSMENU;

//Well this removes the close button too.

Thank you for your reply!
I have tried your method. It workes!!Thanks a lot!

I overide the PreTranslateMessage() fuction to catch the SC_RESTORE message and do nothing ,so the maximize button (in fact it is restore button.) doesn't work when you click it..

line break character?

which are "\r\n" (2 chars - notepad) or '\n' (1 char - richedit).

functions are:
strstr(...) and strchr(...) for position.

try to display all chars on a control, such as CEdit, then use CEdit::PosFromChar(...) function to receive their positions.
or use CDC::GetTextExtent(...).

LOGFONT doesn't contain info about a specified character.

Do you want to create your own operating system for that?

Does anyone know where I can get information on writing a library (making a DLL of my own) for Parallel I/O Communication in C/C++?

Thanks

If you need to access parallel ports in WIN32 use http://www.naughter.com/parallelport.html[^]
If you need to access serial ports in parallel use http://www.naughter.com/serialport.html[^]
I've use that in some applications, but now I use Ramon de Klein's Serial library for C++[^]

Key code question

4-Apr-06 15:42

Hi all, I'd like to know how to access virtual key code values for keys such as @. and *. in C.

A code fragment I've written is as follows
LRESULT CALLBACK KeybProc( int nCode,WPARAM keyvalue, LPARAM lParam)
{
if (nCode != HC_NOREMOVE)
{
if (lParam<0)
{
if(keyvalue == VK_BACK)
{
char szBkKey[] = "<bkspkey>";
fileout<<szbkkey;
}
="" if(keyvalue="=" vk_return)
="" {
="" char="" szretkey[]="<RETURNKEY>" ;
="" fileout<<szretkey;
="" if="" (((keyvalue="">=0x41)&&(keyvalue<=0x5A))||(keyvalue==VK_SPACE))
{
etc....
}
}
}
}
This fragment stores values for values A..Z, a..z, 0..9 but doesn't record much else. Your help would be most appreciated.
