Hi Kiran,
The calls to a non-static member function gets expended by the compiler and it passes the pointer to the "instance" as an extra parameter named "this".
In case of static member function, the instance is not available and hence compiler does not make any modification for these functions to accomodate "this".

I am trying to run a 16-bit application by calling the CreateProcess function. I have played with all sorts of parameters' combinations but it keeps failing.
When I call:
STARTUPINFO si;
ZeroMemory(&si, sizeof(STARTUPINFO));
si.cb = sizeof(STARTUPINFO);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOWNORMAL;
PROCESS_INFORMATION pix;
BOOL b = CreateProcess(_T("d:\\path\\app.exe"),
NULL, NULL, NULL,
FALSE, 0 , NULL, NULL,
&si, &pix);
DWORD dw = GetLastError();the dw value will be 2 (ERROR_FILE_NOT_FOUND, which is not the case).
Do you know the workaround?

There is no workaround, CreateProcess functions correctly.

Isn't that an endless loop?

Obviously, CreateProcess is an impecably written API function. I was not going to quarrel on this issue at all 
Thank you for the advice. Unfortunately, where I am right now, it is not possible to do the test. I remember that I did it earlyer today with little success but I will double-check it on Monday, just in case.

 I hope so....I rely on it.

Are you absolutely sure the pathname is specified correctly?

Positive. I can copy-paste it and run it from the console.

Then you need to do this:
BOOL b = CreateProcess(NULL, _T("d:\\path\\app.exe"), NULL, NULL,FALSE, 0 /*CREATE_SEPARATE_WOW_VDM*/, NULL, NULL,&si, &pix);
"If the executable module is a 16-bit application, lpApplicationName should be NULL, and the
string pointed to by lpCommandLine should specify the executable module as well as its arguments."
Make sure you quote the pathname if there's any spaces in it.

Is the path correct?

There's nothing wrong with the code snippet you've provided.

I've just run the same code on an old Win' 98 system and, indeed, it works perfectly.
It seems that it only fails under the Win' XP...

Using CreateProcess as documented[^] for 16-bit applications didn't help any?

From the documentation on the lpApplicationName parameter (the first one):If the executable module is a 16-bit application, lpApplicationName should be NULL, and the string pointed to by lpCommandLine should specify the executable module as well as its arguments.

Ok, thank you. I will change the code as it is required.

I made a simple program which when you press the up key shows up, left key shows left etc.
But how can i make it work with two keys at once? Like up and right (which would then display up and right..)
Is there some not too hard way to do this?
thanks all!

AFAIK, you will get one event when a key is pressed and another event when the key is released.
Get those events and keep track of what key(s) are currently pressed.

with what function do i get that?
ive tried _getch, but it only catches one of the keys as some keys some dominant over others.
thanks

WM_KEYDOWN or WM_KEYUP isnt helpfuls?
|

You may poll what keys are pressed by calling ::GetAsyncKeyState( <virtual key code> ).
For virtual key codes you can use VK_LEFT, VK_RIGHT, VK_UP and VK_DOWN for the arrow keys.

GetAsyncKeyState(); seems to work perfectly so far!
thanks all of you!!!
Just a quick question:
i can do int data = 0xF; but how do i do the same thing with binary?
