The world champs are for Sporting which is a form of Clay Pigeon Shooting == Shotgun

Haven't shot a pistol in years, my other shooting involves Air-Rifling (High-powered[^], i.e. it requires a firearms certificate here in Britain) with a bit of rifling, .22, .243 & .303.

Now that sounds like fun! I was talking to my brother over the weekend about shooting guns and I must admit that I reakon is would be a real blast - pun intended. I've shot a .22 and a slug gun when I was a kid but that's about it. I've still to check off the shotgun! It's got to be on the list of things to do at least once! Well anyway Ed, good luck and bring back some silverware! Cool | :cool:

Thanks, I've finally been given the go-ahead by the doctors so I'm definitely off to America now Cool | :cool:

, just wish I'd changed my gun before I went (I've been trying out a friend's gun and been shooting better with it)

Hello,

I would like to add a window to my application which pops up while the application is loading. It also disappears once the application is loaded. I am sure you know what I am taking about. This is what we get with all comercial window applications. I am not sure what it is called or how to go about it.

I truly appriciate your help in this matter.

What you are talking about is a splash window.

There are a lot of examples out there, now you can search for them. Smile | :)

Its called a splash screen

if i model robot arm in 3d max than can i...?

13-Feb-07 12:36

There are two ways to implement them and one of the ways is very wrong. Splash screens must be in a seperate thread from the main application if they are to be effective, unless they are just eye candy.

if i model robot in 3d max than can i do real time simulaton on XAML?i mean i want to control robot arm that is modelled in 3d max etc.angle variables will be in visual c#.my mechanic robot arm's any axesses are rotated than simulation will be rotated too.XAML can do it???.when i make this steps so can i do this simulation?
1)modelling my robot arm in 3d max or like this programme.
2)get angle variables from visual c#.
3)use these angle variables in XAML and rotates robot arm.

Are these steps true?

Custom Compiler Warnings

Re: Custom Compiler Warnings

When you use the ObsoleteAttribute it generates a nice compiler warning when implementers use an obsolete method.

I would like to be able to create my own attribute that, if placed on a method and then referenced in a similar fashion, generates a customer compiler warning, or even error.

Ie.

[MyAttribute]
public class Foo{}

public void SomeMethod(){
   Foo foo = new Foo();
}

Would generate my own compiler error or warning.

Looking at the code for the Obselete attribute under Reflector there's nothing special inside it but I was wondering if you ~~inherited from it~~. It's sealed sorry, can't do that.

Ya see my problem!

Ennis Ray Lynch, Jr.13-Feb-07 14:23

Plus I want custom warnings as well. Theres got to be some way for an attribute constructor to detect if the runtime is a compiler and then register a warning with it but I do not know. Web searches have been fruitless and I have been lazy Smile | :)

I know, it would be interesting to know how to do this so I did some Googling and nada. The only way I can think of is possibly building an add-in but that'd only work for VS and is no where near as elegant or reliable. I shall keep looking though.

USB Control

Is there a way to control Voltage output of a USB Port. I'm trying to connect a custom made circuit through USB and send power on request to it.

I don't know but if you can the answer would be here http://www.usb.org/developers/docs/

AFAIK a USB can only supply a maximum of 5V anyway and I think it's fairly constant, that's why big devices such as printers have to be plugged into the mains.

DRVoodoo15-Feb-07 5:08

15-Feb-07 5:08

Yeah... 5V is plenty ...however, I need to know if I can trigger the supply voltage on and off somehow. I don't need the USB to supply me with any power, but just act as a switch. I haven't had much time to research this, thanks for the replies so far.

Ed.Poore15-Feb-07 5:30

15-Feb-07 5:30

I'm pretty sure that the power is supplied constantly in most cases, it'd probably be wiser to use the data line and when it's on transmit 0xff continuously and when you want off transmit 0x00.

DRVoodoo15-Feb-07 10:41

15-Feb-07 10:41

Interesting. If I recall correctly the Data lines supply 3.3V when transmitting and 0 when not ? If so that's great. Now I have to find away to communicate with the USB Port itself via code. Thanks for the replies.
