From MSDN, Use srand() to seed the random-number generator
/* RAND.C: This program seeds the random-number generator
* with the time, then displays 10 random integers.
*/
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
void main( void )
{
int i;
/* Seed the random-number generator with current time so that
* the numbers will be different every time we run.
*/
srand( (unsigned)time( NULL ) );
/* Display 10 numbers. */
for( i = 0; i < 10;i++ )
printf( " %6d\n", rand() );
}
Output
6929
8026
21987
30734
20587
6699
22034

Does anyone know how to create a progress bar in the cell of a ListView? I have a list of tasks that i have in a listview, and would like to give each of them a progress bar as they are completed. Any ideas? Thanks much!
Cheers!

Call ListView_GetSubItemRect() to get the RECT for the cell you want. Create the progress bar in that RECT, with the list control as the parent.

Dear experts,
I have create a usual listbox in Visual C ++, the problem is how to change the size and type of the word in every line.
Could you please give an idea ?
best regards,

Use the "owner draw variable" style for the list box. Using that, you can have each item be a different height, and draw with whatever fonts you need.

Dear friends:
I am a student in Beijing Polytechnology University.
I am learning computer application.This year I will graduate,so I

I presume you want to extract letters or numbers from images of number plates?
Start with:

and
http://www.cs.cmu.edu/~cil/v-source.html
for some packages that might give you some ideas...

I have created a class derived from CTreeView to display some pieces of information about files. Among these pieces of information, I want to display code lines, and unfortunately tab characters ('\t') are replaced by invalid characters whereas I'd like them to be replaced by a fixed number of white spaces.
What should I do to modify my class and to display tab characters as a fixed number of spaces ?
Thanks.

i afraid with system tree ctrl you have to change them to spaces before you set item's text
t!

RTF has codes for drawing a line, but the RichEditCtrl in MFC doesn't support this. Does anyone know of a control that supports this ? Or has anyone an example on how to do this with the MFC-control ?

Don't feel bad, CCheckListBox has quite a few shortcommings that tend to get a little annoying.
look up CLBN_CHKCHANGE in MSDN - it's a good start.
I got so frustrated with CCheckListBox that I ended up coding up my own version just to get around it's issues. (Hmm, maybe I should post it...)
Good Luck & Happy Coding

AM making a basic game, its just 2 icon's on a dialog aplication.
One of them control.
But i want to show a message when they overlap each other. Like a collision, but i cant find any tutorials on this one, am rather new.
Thank's

ummm ... when we used to code games (way back when) we had to do collision detection manually ... you keep a list of the sprites (icons in your terminology) and what their current screen positions are ... as they move (each frame of the game usually) you check for collisions with a simple co-ordinate checking algorithm
hope this helps

ahh like this
if icon1 pos y2, x3 && icon2 pos y2, x3
{
do somthing
}
ok but, how do i get the pos of each icon?? (figure)
thank you..

i assumed you would be moving them around under either program or user control ... therefore you will have a structure of some sort holding x,y co-ordinates and some other stuff (image number if cycling, etc etc) ... as u move them u keep the co-ordinates updated and do collision detection on the bounding shapes (usually rectabgles or squares) to see if one overlaps the other ... then u have a hit
s'easy really

Right now i got 2 icon's
One i control
And the other is a object
And i made a control that every time its pressed, moves the icon +10y direction
It works great but i dont know what codinat it was on, i think if i placed the icon
in cod y10, x10, and then plus 10y every time i press the button, then i know where it is,
with some BASIC math, y20, x10.
But i want to example print the 2 icon's codinat's to a text box
and compare the to icon's codinat's with each other. And if they are equal
They hit.
But i dont know how. 
THANKS

ok
so they're floating around a dialog box ... presumably you would know where they started out and could keep track that way or you could use the GetWindowPlacement function on the icons (buttons, whatever)
also dont look for an exact match of co-ordinates but use a collision hotspot area where you say, for example, that if they overlap in any way by x pixels there is a hit

Eh, it sound's easy, but i dont quite understand
Do you have a simple source file i could look at
