This isn't necessarily a C# question. Any ideas how to prevent PrtScn from doing it's thing?
I know there's a variety of screen capture programs out there, but let's assume for the moment that the client's environment is sufficiently controlled that a third party screen capture app isn't an issue. But we do want to stop the built-in prtscn from working so that an unscrupulous client can't take screen shots of sensitive information.

i think he meant printscreen, not portscan... either that or im even more confusticated than i thought . 
on the other hand, listening to open ports to stop a a printscreen sounds like an interesting challenge for masochists

How about a keyboard hook that gets loaded at system startup and swallows all PrintScreen keypresses?

I agree with Kumar. A keyboard hook will let you stop the PrintScreen key from ever reaching the system. I wrote up something similar in C++ a few years back to eat the Windows key.
I also seem to remember hearing somewhere that if you change the Opacity of the form, even to 99%, PrintScreen won't see your form. Try it, see what happens. But the down side to this is that it might not work like this with all video drivers and versions of Windows, especially future versions. Ack! Forget I mentioned it!

Is your keyboard broken?
Without meaningful interpunctuation it's hard/impossible to understand what you want.
Try forming full sentences ending in a full stop (.)
That way somebody might be able to understand and help you.

How to drop down an activeX component on the form?
I used to write programs in C++, and in the Visual C++ it is easy to click it on menu "Add ActiveX Component", bud i can't find the same menu in the C# IDE...
|
|
|
|
|
Open up the ToolBox (View->Toolbox). Right click in an empty area and click "Add/Remove Items". Go the COM Components tab. You should see you ActiveX control there. You can then drag and drop the control from the toolbox to a form.

Since you didn't specify which IDE you are using for writing C#, I am going to suppose you are talking about Ms Visual Studio .NET 2003 which is the most common one.
Right-click on the toolbox and click on the "Add/Remove Items" menu item. This should pop-up a dialog with two tabs; the ".NET Framework Components" and the "COM Components". The latter one is the one you are after. Tick the components you want and click on OK. (Note that if they are not listed you can browse for them). Click on OK.
Now you can look for them on your toolbox. They should be on there.
Hope this helps.

I set an object to clipboard
then when I get from Clipboard I get null value.
my code is here.
Class1 cls = new Class1();
cls.str = "Test string";
Clipboard.SetDataObject(cls);
IDataObject a;
a = Clipboard.GetDataObject();
Class1 aa=new Class1();
aa = (Class1) a.GetData(cls.GetType());
anyone help me!!!!
thanks in advance.

the problem here that you cannot set all data to the clipboard. the clipboard cannot handle all types of data. it can only handle data in the formats given in the enum DataFormats.
example:
string str = (String)iData.GetData(DataFormats.Text);

Is it possible to invoke API function RegisterClass in C#? I need to register a new class, and handle messages for it. How can I do that?

What exactly do you want to do? If all you want is a message pump, you can call Application.Run() passing the form as a parameter. That'll handle the messages and fire appropriate events in the form for you.

I have an app written in VC++ 6, which sends out some data via WM_COPYDATA to all instances of windows created with a specific class name. In order to be able to receive those data in VS.NET i need to have a window created with exactly the same class name. How can I do that?

You can try deriving your own class from System.Windows.Forms.Form and override WndProc. That way, you'll be able to see all messages sent to the window. But I've no idea how to set the class name.

I knew I could do that much, but the trick i need to do is with API function RegisterWindow. I can import it in without problem, but it takes WNDCLASS structure for initialization, which has one field - pointer to the function that will receive all windows events. And I don't know how to declare and initialize such field correctly. I know that in VB6 you could do that by using keyword "AddressOf" to get address of a function, but i don't know how this works in C#.

I can check whether there is a collision for between two objects
eg. Rectangle boxrect = box.Frame()
if(char.Frame().Intersectswith(boxrect)
but i want to know if i can check whether there is a collision with anything in the room at the time.
If so could i do this, then use a switch(*what it intersected with*)
to do different things depending on what the character is intersecting with, instead of doing a check for every single thing in the game
