hi!! i'm just a newbie here... sorry for the disturbance... but i really need your help guys... i need to do a project using these physics equation... sad to say, i dont know how to do it in visual basic 6.0.. its pretty hard for me to do the coding... please help!!
1) K.E.=1/2mv^2
2) G.P.E.=mgh
3) P=Fd/t or P=Fv
i know its pretty simple for you guys... but for me.. i just can't understand these things.... so i hope you guys can help me... thanks a bunch!!!

Heck, I'd love to help if I understood what the heck the equations meant. Can they be expressed like A x B + 1 + 3 + (C / 4) type of thing?
Your topic is VB6 / VB.NET, I dont have VB6 on my system anymore, so if you could take this in VB.NET I'll happily squirt the code back to you after some clarification of what that stuff means 8-)

Hey,
Same as cnurse here, I don't understand exactly what you meen but I assume you are looking for a way to use advanced calc functions.
I am no math wizz and BY FAR no physics wizz so I can't tell you step by step how to get those calculations by any meens but if it helps I can tell you that there are no advanced math functions in vb (or any language i know of) so you will have to work out how it is done step by step useing basic functions (+ - * and /)and do it line by line.
For eg. if you want to multiply by a percentage vb doesn't have a way to say
100 plus 50% so you will have to devide the 50 (50%) by 100 then multiply it
dim number1 as integer = 100
dim number2 as integer = 50
dim result as integer
number2 = number2 / 100
result = number1 * number2

sorry didnt mean to misled you guys... what i meant was, how do you trun these equations into vb samples...
1)Kinetic Energy=1/2*mass*velocity squared
2)Gravitational Energy=mass*acceleration due to gravity*height
3)Power=work(that is mass*acceleration due to gravity)*distance/time
i know its dumb for me to ask... but forgive me guys... thanks a bunch for helping me out.... i need your help badly....

OK, thanks for the clarification....
A = B x C in VB Speak....
Sub DoSomethingClever()
Dim A as integer ' Here is an integer number, can't handle decimal parts
A = 10 * 10 ' A = 100 i.e. A = 10 x 10 the * is x in progrmaming terminolgy
Dim B as integer
B = A * 10 ' Now B = 1000 get it so far?
Dim C as integer
C = B / 100 ' Now C = 10
Dim MyWage as Single = 100.55 ' Make a floating point variable and assign it value in 1 step
MyWage = MyWage * 1000 ' I wish! No wage is multiplied and stored back into the variable as 100550.00
End Sub
You can do things like this now
A = A / 2 ' A is divided by 2
A = (B*B) ' A = B^2
A = B + C
A = A - B
All of the above are things you can type into VB literally and they will work.
I think there is a mathematical function called power or pwr which raises a number to a given power.
If you are in VB.NET look up the Math namespace as it contains all the cos sin and tan functions to name a few.
This ain't the answer to your functions but you can work it out now. If not then shout for more help. I think you do need to read a little about Sub's and Function's and where to use them. For example
private function MyAge () as integer
Dim a as integer = 21
Return a
End Function
A short example of creating a variable, assigning it a value and returning that value, therefore...
Dim B as integer = MyAge
Assigns B the value 21, because VB calls the MyAge function which "Returns" the value of a which = 21.
Clear as mud, I know, but I'm trying to help you find the answer rather than just spew lines of code that you might not understand if things go wrong.

Hi,

Use a timer on your app and reset it when the mouse moves or the user presses a key. When the timer reaches a certain point, the timer event is triggered and you can do whatever you want.

I am not sure what you mean.
But if you are trying to read a text file with a useing visual basic.
You would do something like this.
Dim my As IO.StreamReader
Dim fileInfo As string
Then something like
my = IO.File.OpenText("A:grades.txt")
fileInfo = my.ReadFileToEnd

But when I install application proxy on winxp then it doesn't seem to invoke the queued component .
Is there any compatiblity problem between win2k and winxp or there is some settings to be done?

The service has been developed using VB.NET and VS.NET on an XP platform.
On the XP platform, when I install a new version of this service it starts
by removing first the previous version, which is what I expect. Everything is
OK.
On a Win2003 platform when I want to install a new version of the same
service:
1. It does not remove the previous version
2. However, it interrupts installation because the service is already
installed
3. The service is not listed in the add/remove applet so I cannot remove it
from there.
Many thanks in advance for your help,
Anadin

Vimal, You probably need to look at TAPI, the telephony API. In VB there are a few off the shelf components available. Lookup Exceletel on the web. They have a suite of tools for placing and handling calls. Be warned. This area is a minefield.
