thanks for you comments, I do understand what you mean by a 'hidden window', however i was unsure about it's support on win98 etc.
Thanks for the code frag.
I have decided to use a WH_CALLWNDPROC HOOK for this solution.
and monitoring
WM_ENDSESSION message.
Thanks very much for your help.

I`ve got kind off a complex situation here.
I have a class hierarchy that looks like
class A
class aB:public A
class aC:public A
class cD:public C
with further derived classes, but for illustrating this`ll do.
in class A I define some constants like
#define CONST_A_1 1
#define CONST_A_2 2
...
if class aB needs to I should be able to define a series of constants there that continues where the series of #defines in class A stopped.
e.g. if last const in class A was #define CONST_A_X x (where x is a number)
then CONST_aB_1 should get value x+1.
Ok this is easy I could just define in class A #define CONST_A_LAST CONST_A_X
and set the definitions in class aB like
#define CONST_aB_1 (CONST_A_LAST+1)
#define CONST_aB_2 (CONST_aB_1+1)
...
Now imagine that the constants defined in A are good enough for aC(no extra needed), but I need some more for cD...
I could define them in cD as i did in aB like #define CONST_cD_1 (CONST_A_LAST+1) and so on, but what if due to specifications I don^t have yet I will need to define a constant in aC later on? Then I will need to change the defines in class cD too (at least the first one,because I don^t want a constant with the same value in base-class)....
From the start I could define in aC something like #define CONST_C_LAST CONST_A_LAST
and use that CONST_C_LAST as a starting point in cD.
However I don^t like the above approach( although it might be the only one??)
The thing is each time I would derive a new class from one of these classes I would need to remember to define a new "CONST_..._LAST" constant (in case that I derive a class from that class and need to specify a new const).Which might lead to a lot of unused defined constants (doesn^t hurt, but I don^t li
Does anybody know how I could solve this issue here in such a way that I can remove/add new constants to a class without needing to worry about derived classes of that class. Or derive classes without having to remember adding a CONST_..._LAST if I don^t need it for that class, but still be able to derive a new class from that one and start with a correct constant without bothering base class, and in case base class suddenly needs a constant adding it there without bothering derived class.
I know sounds like a lot to ask for. But someone might know a solution....
Thanks for any insight you might provide.
Greets,
Davy

It can be a solution for all platforms, only you have to create a normal window - not message only - a bit more overhead, but should work.
If you want to receive a message, you need a window (WM_ stands for Window Message  ) for window you need a message pump...
Or might be there will be a better way how to detect the windows shutdown, but I don't know them from the head now.

GetKeyboardState((LPBYTE)&keyState);
if( (TRUE && !(keyState[38] & 1))||(!FALSE && (keyState[38] & 1)) )
{
// Simulate a key press
keybd_event( 38,0x45,KEYEVENTF_EXTENDEDKEY|0,0);

Hi,
I am working with MDI application. I want to ovverwrite ID_APP_EXIT, File->Exit menu function of Mainframe menu. When I click on this menu option or on the close icon button of Main frame, I should check for a particular condition and then allow to exit the application if condition is true or else I should not allow the user to exit.
I am able to overwrite and check the condition, but unable to close the application if condition is met. If I used PostQuitMessage(0), it's getting closed but I'm getting lot of memory leaks due to this function.
Can anyone please help me to do this?
Thanks
Madhavi

Try
AfxGetMainWnd()->PostMessage(WM_CLOSE);
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

Everywhere it says: "Create project by going to Other Projects/Extensibility Projects". I don't have that! OTOH I don't have the Pro version of VC++. Is that needed ? I've download the VSIP 2003 SDK, that don't help either

Thanks, but... that was what I said. There are no "Extensibility Projects" and thus no Add-in wizard

Hi!
I need to draw some information on screen, without having to create a window. Here my code:
<br />
CWnd* pDesktop=GetDesktopWindow();<br />
CDC* pDC=pDesktop->GetDC();<br />
CBrush* pOldBrush=(CBrush*) pDC->SelectStockObject(BLACK_BRUSH);<br />
CPen* pOldPen=(CPen*) pDC->SelectStockObject(NULL_PEN);<br />
pDC->Rectangle(0,0,100,100);<br />
pDC->SelectObject(pOldBrush);<br />
pDC->SelectObject(pOldPen);<br />
pDesktop->ReleaseDC(pDC);<br />
This code is not working, nothing appears on screen!
What's wrong? Do I need to create a transparent window and draw on this window?
Thks in advance!

Hi. I’m a VC++ programmer that have plans to use some functionalities from MSN Messenger into my programs.
I need some kind of tutorial on how to start… I’ve earlier coded against MS Outlook and MS PowerPoint so think I could get most things quite fast.
Really need some tips on where to start!
