Handle WM_GETMINMAXINFO. Use AdjustWindowRect[Ex] in the handler to compute frame size based on bitmap size.

Is it possible to access eg. CTreeDoc from CTreeView and CArtView?
I use:
CTreeDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
in the CArtView::OnDraw(), but it won't let me access the member functions of CTreeDoc. What do I need to add?

Hey does anyone know how to put a DWORD into a BYTE Buffer
without converting it or using the string functions. ie what would be the code behind the string functions that does it.
Cheers

Why do you want to copy a DWORD into a BYTE buffer?
Anyway, how about something like this...
(I have just written it in the browser, so there might be syntax errors...)
DWORD dw = 65535;
byte b = (byte*)malloc(sizeof(DWORD));
memcpy(b, dw, sizeof(DWORD));

There is also
*((DWORD *) b) = dw;
But that has some minor drawbacks on many CPUs. If b is not aligned on a DWORD, you get an alignment fault. Luckally, that isn't a problem on intel processors.

I hope that you have seen the web browser called "NEO-PLANET". Its user interface is really interactive. I want to create such user interfaces using VC++. Please help me in this regard.

there are one const memeber constM and one const function constFunction
#classA head file
class classA
{
const int constM ;
const int constFunction ();
}
class classA::constM;
#end of classA head file
#classA cpp file
int constFunction (){return 0;};
#end of classA cpp file
#fileB head file
#include "classA.h"
void main()
{
};
class fileB::cons
compile error:
two obj file LNK2001
Help!!Help!!Help!!
Please pardon my weak English!

Place you "class classA::constM" in the classA.cpp file. Having it in the H file causes it to be defined in every .CPP file that includes classA.h.

Hi, all.
========
Under win98 file name longer than 8.3 appear with "~1" in DOS.
example:
--------
Win98, the file looks like this:
filename longer than 8 chars.dat
DOS, the file looks like this:
filena~1.dat
Does anyone know where the filename is stored, and how does it work?
thanks!!
BTW: come to #CodeProject on DalNet (mIRC)

The long file name occupies multiple, linked entries in FAT directory. These entries are marked with attribute combination which was never used in any version of DOS. When you save file with a long fn to floppy and read this on a machine running DOS (do you still have one?), these directory entries are ignored by operating system.

so...
if I understood right:
long file names and short file names saved on the HD the same way but the Operating System reads it differently

Is it always taking a long time, or is it just when the program cannot connect to the server that it takes a long time?
If it only is when it cannot connect there is really not much to do about it.
If the program try to connect to a server that does not exist, it sends, (windows socket standard), a SYN packet to the ip-address, and wait for some time for an answer (a SYNACK packet), if it don't get the answer it tries 2 more times.
It takes some time, about 30 seconds, I would say...

Can someone give me a little example of code how to use the VK_UP key in MFC.
I want that if I press the "up" key a messagebox should appear...
|
|
|
|
|
You want to capture WM_KEYDOWN, WM_KEYUP or WM_CHAR, then it's a case of doing a switch on the nChar variable passed in:
switch (nChar)
{
case VK_UP:
AfxMEssageBox("You pressed up");
break;
I generally go for WM_KEYDOWN.

But Why it doesn't work with VK_RIGHT and VK_DOWN?

Are you subclassing a dialog control?
If so, you will need to handle the WM_GETDLGCODE message to inform the dialog that you want the arrow keys.

I create a default empty MFC "dialog based" and OnKeyDown is the only function I have... and I have deleted all controls from the dialog... and only the VK_RIGHT and VK_DOWN don't work...
but thanks... I try it with WM_GETDLGCODE

Cast NMHDR* to NMTREEVIEW*. itemNew member of NMTREEVIEW contains information about tree item that expands or collapses.
