Will you please give me provide me any such file's complete .dsw file. It will be very helpful to me. I don't have much time, charles petzold book have so many such files but at present i don't have that book and i have to submit this project in 1-2 days. Please help me and do the needful.
Thanking you in advance.

Hi,
#define GetRandom(min, max) ((rand() % (int)(((max) + 1) - (min))) + (min))
I found this algorithm from this discussion forum. However, i found that every time it produces the same "sequence" of output. For example, GetRandom(2, 100), the sequence is 43, 55, 99, 69, 64, 84, 95, 56...............
Since i'm doing multithread, my threads get the same result when they call it.......... so...............can anyone help me???
Thanks!

rand is a psuedo-random number generator. That means that the same sequence of numbers will be generated each time you use it in an application, however, the sequence of numbers that it generates are uniformly distrubuted. Which means that they are essentially random.
You can make the sequence become random each time you run your app if you seed the number generator with the srand() function when your app or thread starts up. The current time may be a good value to use to seed the number.

If you use Srand() before your random function,then this won't happend.

Sorry, I don't quite understand how to use srand()????
i found this in MSDN: ( and i implement in my program)
srand( (unsigned)time( NULL ) );
GetRandom(2,100)
but everytime i run it.............it is increasing order.......until 100.......
e.g.
31, 33, 33, 35, 38, 42, 47.......89, 99, 3, 5, 10, 15, 22....
What is the problem then?

Use srand( (unsigned)time( NULL ) ) only once at the beginning of the program to "randomize" the sequence generated by GetRandom. Do not use it every time you call GetRandom.

I am working on a custom drawn menu. I am able to get the rect of the menu items, but the rects coordinates are not in relation to the screen. How can I get the menu items cords for the screen?

Thats what I thought too, but CMenu is derived from CObject not CWnd. So how do I get the window handle for the menu. Is that even possible?

Maybe GetMenuItemRect will help? It returns a rectangle using screen coordinates.

Perfect... One more question. Is there an equivilant function to get the rect of the whole menu not just each item?

I am a novice student who's trying to learn MFC.
I am trying to access a chipset using i2c.
When I download about 6k byte of information through i2c in DOS program it takes less than 10 seconds, but when I program a download program with MFC, it takes more than 2 minutes to download through i2c.
Please someone tell me what I am missing here, or recommand me a book or something that I can solve this problem.
Thank you

Hello,
I am trying to convert a large integer(in a string form) to integer using StrToInt64Ex function. MSDN suggests that this function is defined in shlwapi.h, but it is not defined. I am using Visual C++ 6.0 on windows 2000. Source code is enclosed with the error message here below. Please someone tell me what is wrong with this code ? Is there any other method to convert a large integer? How to proceed further?
Thank you.
Regards,
Mainak.
==============================================================================
#include <windows.h>
#include <Shlwapi.h>
#include <stdio.h>
#include <stdlib.h>
int main ()
{
// with StrToInt64Ex
__int64 a2;
char s2[] = "0xffff";
LONGLONG a3;
StrToInt64Ex (s2, STIF_SUPPORT_HEX, &a3 );
return 0;
}
Compiling...
main.cpp
C:\tmp\str\main.cpp(19) : error C2065: 'StrToInt64Ex' : undeclared identifier
Error executing cl.exe.
str.exe - 1 error(s), 0 warning(s)

This is only supported for IE 6.0 or higher. You'll need to add:
#define _WIN32_IE 0x0600
to stdafx.h before the other includes.
(If you look at shlwapi.h you'll see it's wrapped in ifdefs for this value)

I upgraded to IE 6.0 still it did not compile.
The header shlwapi.h (version 1) does not have the
function proto. What is your PC configuration?

Instead of StrToInt64Ex, which isn't supported on older Windows version, use plain old sprintf with %I64x or %I64d format specifiers:
char buf[32];
__int64 v;
v = 0x1234567890abcdef;
sprintf(buf, "%I64x", v);
