I don't realy understand what you want. 
but I have a define for ya:
#define GetParam(arg,num) (((int *)(&arg))[num])
the GetParam will give you the arguments of the function.
e.g.
func(const char * format, ...)
and call it like this
func("%d %s %c", 123, "123", 's');
than use the get param like this:
int a=(int)GetParam(format,1);
char * b=(char *)GetParam(format,2);
char c=(char)GetParam(format,3);
NOTE: on a 32bit OS you'll have a little problem getting the __int64 value (I'll let u discover yourself how to do that);)

Ack, never write your own argument list picking function. They aren't at all portable. (But of course, if you don't care about portability, more power to you!)

I've been throe HELL, trying to understand the CRT source code, printf for example.
and believe me, it's not much fun.  (i'm still confused)
Portable ? depends on the operating system.
if it's a 16bit OS, arg picking will be by 16 bits pieces.
if it's a 32bit OS, arg picking will be by 32 bits pieces.
if it's a 64bit OS, arg picking will be by 64 bits pieces.
if it's a 128bit OS, arg picking will be by 128 bits pieces.
if it's a 512bit OS, arg picking will be by 512 bits pieces.
...
that's all.
And in order to make portable I have a #define SYSBITS __int32

Not only that. double numbers will be more serious problem.

well to got the 64 bits value (e.g. __int64 or double) we do it like this:
(*** lets say we're working on a 32bit OS ***)
in the .h file:
#define GetParam(arg,num) (((int *)(&arg))[num])
func1(const char *lll, ...);
The arguments come in 32 bits pieces.
There for the 64bits variable will come in 2 pieces (64/32=2).
and we will get the value like this
func1(const char *lll, ...)
{
__int64 l_nNumber;
int pos=0;
((__int32 *)&l_nNumber)[0]= GetParam(lll, ++pos);
((__int32 *)&l_nNumber)[1]= GetParam(lll, ++pos);
}

1) Do you think it's better than va_xxx?
2) Do you think this solves the original poster's problem?

1) what is the "original poster's problem"?
2) I have no problem with it, as a matter of fact it works perfect.

what is the "original poster's problem"?
He wanted to pass va_list from one function that takes a variable number of arguments to another function. Your macros do not solve this problem.

How to register a window class exactly the same as the "View" window except the backcolor in a MDI/SDI application?
Thanks.

Handle OnEraseBackground to change the background colour if that's all you want to change. I don't believe you can change it by creating a Window class ( although I could be wrong ). Full instructions are in the FAQ.

You *can* control the background color in a view by creating a Window class. See TN001 in MSDN Library.

Hi,
In one of my apps I have a class requiering an HBITMAP as input but my
images are all stored as icons.
Does anyone know of a nice way of converting between an icon and a bitmap?
I know the CImageList does this somehow but it is not a very neat solution.

I am writing a class to create our own toolbar in Win32. For Dialog boxes I create a dialog template dynamically and then call CreateDialogIndirect. I want to create a toolbar with the WS_EX_TOOLWINDOW style set, so that the caption and system menu are the smaller size. Am I right in thinking that this means I need to create a *window* with this style, draw the background grey and then add my buttons ? This is a major pain as it means I can't inherit from my dialog class....

Dialogs can certainly have the WS_EX_TOOLWINDOW style. Are you trying this and it's just not working?

It doesn't work if I set the style to include this value, but using SetWindowLong works just dandy - I was about to post and say I'd got it working
I have another problem though - I am currently creating a lot of windows that all have their own 'button' on the status bar, but when I click on some of them they are not shown. I tried handling WM_SHOWWINDOW, to find it's not being called. Can you suggest what I might need to do to fix this ?

I was wondering how can I have a text area liked control in my dialog based application (win32). I try to use the resource editor but cannot find any text area liked control ?
thank you

How is what you want different from the edit box and rich edit control provided by the resource editor ?

Hi,
Am using an owner drawn list control, and I handle the WM_MEASUREITEM message to set the item height. Problem is, this message is sent only when a window is created (or so the MSDN documentation says). I'd like to set the item height, in response to user button clicks (to provide for the effect of zooming items)-this would let the user increase or decrease item heights by clicking buttons. Problem is, as noted earlier, the message is sent only when the list control is created-how do I set the item height, without destroying and creating the control again?
Any help is much appreciated.

The fact that there is no way to set an item's RECT and that ListViews only supports LVS_OWNERDRAWFIXED leads me to believe that you are, unfortunately, out of luck...
Unless, you only have one column in the ListView in question, then might I recommend moving to a ListBox instead... its WM_MEASUREITEM suffers the same problem ( only ever getting called once ), but you can set an items RECT at runtime ( like when the user clicks on it ).
void CMyZoomListBox::OnSelchange()
{
if ( -1 != m_nLastSelection ) {
SetItemHeight ( m_nLastSelection, m_nNormalSize );
}
m_nLastSelection = GetCurSel ();
SetItemHeight ( m_nLastSelection, m_nZoomSize );
Invalidate ();
}

I asked this same question for SendMessage HERE once before. However, it appears as though the solution for SendMessage does not work for PostMessage.
I want to pass a CString as one of the parameters of PostMessage. How is this done?
