All i did is to add a reference to it from the
add reference dialogue of the project menu item.

Can you clean the debug folder and then try again.

I have done this, and still getting the same
error after first compilation attempt.
thank you.

Dear All
I'm .Net developer. In my project, When I compile a DLL in Vista PC and run it from the same PC It didn't response. When I disable DEP it responded but took too much time. But the same DLL which is complied in Xp machine response very quickly in Vista PC.( Complied in Xp and run in Vista)
What might be the reason for this greater performance issue?
Thank you,
RSumanan

Not knowing what the assembly does, how it does, how its used, what hardware configuration you have, what other processes are running, etc., don't you think this is a difficult question to answer?

Hi Mark
The purpose of the application is to cut a Autocad .Dxf file in to small several sections. One Exe and several DLLs are in my application. Exe and some Dlls refer other Dlls.
hard ware configurations :
Operating System: Windows Vista™ Business(6.0, Build 6002) Service Pack 2
System Manufacturer: INTEL_
System Model: DG965RY_
BIOS: Default System BIOS
Processor: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz (2 CPUs), ~2.4GHz
Memory: 2020MB RAM
Page File: 1269MB used, 3009MB available
I don't think the reason for this problem is either hardware configurations or other processes since both binaries were executed at same machine. I tested this again and again but result was same. Since all environments were identical and only compilation is done in different Operation Systems, I guess this problem is some thing related to compiling binaries in Vista and XP.
Is there anything like DEP (Data Execution Prevention) that We need to attend in vista? I have disabled the DEP too.
Thank you,
Regards,
Rsumanan

You completely missed the point. Without seeing your complete code base there is no way to determine what is happening. Perhaps there are threading issues, perhaps a Windows API issue. Many things could be issues. There is no way to determine from the information you have given.

Dear Mark
I'm a fresh graduate and new to this field. some time I may be wrong. But What I guess is, If this is due to the reasons that you mentioned above, How does the XP complied one performs well in the vista PC? Threading/API issue should affect both DLLs, Isn't it? Could you suggest any areas like DEP which affect the binaries at build time?
Thank you,

Hey everyone, I'm sorry I'm asking this kind of question but I completely lost my logic today and need your help on this..
You see, it's a simple bouncing ball application, how can I make the ball bounce randomly and freely in the screen and still look natural.. Many thanks guys, here's what I'm doing now:
if ((y + h) >= ScreenH)
CurrentDirection = BallDirection.Right;
if ((x + w) >= ScreenW)
CurrentDirection = BallDirection.Top;
if ((x) <= 0)
CurrentDirection = BallDirection.Bottom;
if ((y) <= 0)
CurrentDirection = BallDirection.Left;
switch(CurrentDirection)
{
case BallDirection.Bottom:
x += step;
y += step;
break;
case BallDirection.Top:
x -= step;
y -= step+7;
break;
case BallDirection.Left:
x -= step;
y += step;
break;
case BallDirection.Right:
x += step;
y -= step;
break;
}
pb.Left = x;
pb.Top = y;
Invalidate();
}

Thanks Eddy, unfortunately it doesn't help me!! I need a free bouncing behavior of one ball against walls.. Would you be a dear and look at my code?? I'm sure someone like you can figure out something I didn't
Thanks Ed.

I was guessing that you were stuck on the gravity-part, adjusting speed when you hit a wall. What are you exactly stuck with, and how can I help?

I did honey, and you stated that it didn't help.

Thanks Ed. I just wanted the angle of the movement to change randomly each time I hit the walls.. and I'm not a honey 
BTW: I felt sorry yesterday for your world cup loss, you did wonderful nevertheless

Muammar© wrote: I just wanted the angle of the movement to change randomly each time I hit the walls..
That would give an unnatural effect, a bounce needs to be the opposite of the approaching direction and speed. Then there's acceleration, unless you want the ball to bounce at a constant speed.
To translate this to your code; the current speed of your picturebox is determined by the Step variable?
Muammar© wrote: and I'm not a honey
Hehe, point taken.

Thanks for the sentiment - I don't understand even the basic rules of the game, so I can't have an opinion really. The only part that I saw in the reruns this morning is a karate-kick in the chest of a soccer-player.

You're doing it the hard way, why not just store a speed vector? (and don't create a struct/class for it, just store two ints or floats somewhere)
Speed can be negative, depending on the direction.
It will also make it much easier if you decide to do "other funny physics things", like gravity or other accelerations; you could just add the acceleration vector to the speed vector every update. (or scaled by time, if your steps are not fixed)
To bounce that way, you can do something like
until no change
{
if (ball outside of horizontal range)
mirror speed horizontally and mirror ball around the edge it hits
if (ball outside of vertical range)
mirror speed vertically and mirror ball around the edge it hits
}

That is a little odd.

That is all wrong. You have a position p (with x and y components), a speed v (with x and y components), and an acceleration/gravity a (possibly with x and y components).
For small time steps, you could evolve like this (apply to each component individually):
p+=v;
v+=a;
where a probably is just a gravitational constant (which happens to be positive since the y-axis is pointing downward in GDI+).
And collisions would invert the relevant speed component, so floor/ceiling would do v.y=-v.y; and left/right walls would cause v.x=-v.x;
ADDED
optionally you could also reduce the speed by some factor (say v*=0.9) on each collision to mimic non-elasticity.

Was I the only one paying attention in school physics classes? You there at the back, boy: what is the difference between speed and velocity? No cheating by looking it up in the text book.
Luc Pattyn wrote: where a probably is just a gravitational constant
"A" gravitational constant? When I was at school, there was only one. I suppose it does make the simulation more interesting if you can adjust the fundamental nature of the universe.

David Skelly wrote: the difference between speed and velocity?
speed, velocity, derivative of position against time, it is all the same vector. If you want to play word games, be my guest.
David Skelly wrote: "A" gravitational constant?
Here "a" stands for acceleration, i.e. force per unit of mass (remember Newton?); there could be many forces, from what the OP tells us gravity could be one of them. There may be other forces such as friction in a fluid, springs, you name it. The minimum to satisfy the OP seems to be a constant due to gravity, hence "a gravitational constant" (which, if you really payed attention isn't really constant, as it depends on distance and homogeneity of the masses involved, but from where he started out, that would be good enough an improvement already).

But speed isn't a vector. It's a scalar. Or to put it another way, it is the derivative of distance against time, not position against time.
Luc Pattyn wrote: acceleration, i.e. force per unit of mass
No, acceleration is the rate of change of velocity versus time.
Luc Pattyn wrote: if you really payed attention
Well, that was always my problem in physics classes. It was just so dull.
Luc Pattyn wrote: it depends on distance and homogeneity of the masses involved,
No, I'm pretty sure the gravitational constant is the same everywhere throughout the universe, which is why it's called a constant.

Experts,
I have created one windows application and deployed it in some 500 machines in my company. The problem is, the applicaiton is updated weekely atlest. I cannot reinstall the .exe once again in all the 500 machines. Any solution for this.........

For that you need to develop ClickOnce application for automatic
update of your installed application.
