bool: false
int: 0
You can find more information in the C# language specification[^], section 5.2 Default values and especially section 4.1.2 Default constructors:
For all simple-types, the default value is the value produced by a bit pattern of all zeros:
For sbyte, byte, short, ushort, int, uint, long, and ulong, the default value is 0.
For char, the default value is '\x0000'.
For float, the default value is 0.0f.
For double, the default value is 0.0d.
For decimal, the default value is 0.0m.
For bool, the default value is false.

Never assume that a variable is automatically initialized. If you want it set to false, then set the damn thing to false.

John said it, don't make assumptions about what it may automatically be initialized to. Especially if you are working on very "critical" software. While on the subject of critical software, you ought to set the warning level to the strictest possible.

I already said it in English, and I don't know any other languages.
If want something to have a default value, assign that value when it's declared. Don't assume the compiler, the framework, or magic elves will automatically do it for you.

Why not write a little test app to find out? If it is of great concern what it is initialized to, why not just initialize it to whatever you need it to be?

Hello,
Is there any way to test the internet connection availability.
Thanks.

The best thing to do is to use the WebClient object to connect to a known website (like google), and looking for an exception to occur. No exception means you're connected.
bool connected = false;
Uri uri = new Uri("http://google.com");
WebClient webClient = new WebClient();
string response = "";
try
{
response = webClient.DownloadString(uri);
connected = true;
}
catch (Exception ex)
{
if (ex != null) { }
}

Hi all,
I recently got the request from a customer to implement an inverse colored version of our winforms application to enhance contrast when using it outdoors. Since the application is quite large implementing this over the whole user interface would be a lot of work. Does anyone know if there's a general system setting I can use to make the application render everything in foto negative colors? I haven't been able to find one, probably because it doesn't exist, but maybe I'm missing something.
Thanks in advance.
Standards are great! Everybody should have one!

I think there is not such thing. Mabe you can try to switch the global system setting to use high-contrast palette.
You can use WinAPI's SetSysColor() function.
Best regards,
Jaime.

Tried this, but this only influences the system color pallet, which means it won't work for my app (which uses a custom pallet). Thanks anyway.

You just need to change the lower palette colors, that are related to the system colors (windows background, caption, border colors, etc)
Best regards,
Jaime.

I did find these, but I don't see how this helps the overall contrast of my app, since (aside from window captions and border colors) these colors aren't used in my application. Besides, changing these colors means changing the windows overall color scheme, which is not something I want to do to my customers. Thanks again.

So, you have a custom palette?
Then, what is the problem? You have to define another palette into your application, and let the user switch between them.
Best regards,
Jaime.

Unfortunately, the good people who designed this application in all their wisdom thought it would be better to just set the colors from the designer. So no, I just have a bunch rgb values in doc file defining what colors should be used where.

in windows XP:
Control Panel -> Accessibility Options -> Display (tab) -> Use High Contrast (Tick box)

Thanks, but that's not really what I meant, I just wanted to set high contrast colors for a single app. Besides, I'm not using the default system color panel, so this won't work with my application.

Oh, in that case, I don't think there is a easy setting you can change.

Double ohh, Now there defiantly isn't a setting for it.
It is winforms or wpf?

It's Forms. Thanks again.

You could look into the possibility of writing a custom control, that took the colour beneath each point in the surface, and inverted it. Effectively acting like a inversion filter, so you'd just display the control over the top of each of the apps form.
Not sure how easy/hard this would be, or even if possible.

I don't think it will work by putting new controls over old ones, but you did bring me to an idea:
I could use reflection to find all controls in my app, then find each field of type Color and invert it. That might do the trick. Think it will work?
Thanks for the inspiration.

Yeah, that sounds like a pretty good idea. Nice one.
