Don't declare the Pen locally. Declare and define the Pen at the form level, and pass parameters to the pen with the Button click.

Unless they are not one pixel wide pens, just use the Pens enumeration instead of creating your own.

I use a Panel as drawing zone and set AutoScroll = True, hoping a scroll will be attached to it automatically when I draw large drawings. But it does not happen. How can I make it?
Appreciate any advice!

Hoho! I get it！
Put another panel as the container of the drawing zone and set AutoScroll = True. When drawing, if the figure is close to the width and height of the drawing zone, increase the width and height!
Excited!

You need to have MS .NET framework on target machine. You cannot just include the dlls and run your application.
It is possible to install the framework through your setup if it is not existing on the target machine. For that you need to include .NET redistributable with your setup.

i've made an application, i want to create an algorithmic to handle a serial number inputted by the user at the first running of the application, and understand if it is one of possible (correct) or not, in this way unlock or not the appliction.
Where can i start by?
How can avoid hacker see my assembly algorithm?

look for www.thinstall.com

Almost no such method is hacker-free. Only thing is how more difficult you can make it.
You can use some hardware-related factors to create your serial numbers / copy-locking methods. You can also have some method to create some random number at the time of the first run of the software. But, you'll have to create your own algorithm. Search "serial number" in Code Project articles, and you'll get some useful material. Here is the first article in this search: http://www.codeproject.com/csharp/hard_disk_serialNo.asp[^]
Alternatively, you can consider some third-party solution. Google with phrases such as "copy protection", "software protection", and the like, and you'll get tons of such third-party applications.

Is it possible in C# app to react on some "USB device connected" event (USB Mass Storage, to be more precise) and obtain its new drive letter?
I have a directory tree and want to refresh it when new drive appears (e.g. flash disc).

You should start using unmanaged code then, kernel32.dll I think. You could also use user32.dll to read system messages. Search http://www.pinvoke.net for sample code.

since it's a "mass storage device" microsoft has a generic driver for it... that's all I know.

Cbeck out some article on Coding4Fun on MSDN. That should tell you how to do it.

I have several classes that make a namespace 'CsGL.Basecode'. In my application i would like to use them (by writing 'using System.CsGL.Basecode'). How to add this namespace into that project easily? Do these classes have to be copied into appropriate folder?
thank you very much for any help

You have to include them in the refernce file.

What is exactly this file name? And did you mean that i have to add them 'manually' or in visual studio?
|
|
|
|
|
In the sollution explorer there should be a reference 'folder' where you can add it. The 'folder' is actualy a file that you can change manualy.
I got Microsoft Visual Studio 2005 Beta 2, I don't know how your VS look like but it should be the same.

There is no way to add a reference via VS (I have VS2003 but as you said, that shouldn`t make any difference), because he accepts only 'component files' (and I want to add a namespace which consist of several classes).
In the 'C# project file' there are 2 possibilities where I could add it:
<Reference
Name = "System.XML"
AssemblyName = "System.XML"
HintPath = "..\..\..\..\..\WINDOWS\Microsoft.NET\Framework\v1.1.4322\System.XML.dll"
/>
<File
RelPath = "App.ico"
BuildAction = "Content"
/>
I tried with the reference but still in main class this was not possible to write using System.CsGL.BaseCode

You could include the source files in the sollution or you could make a class library wich produces a dll that you could include.
When I said to include a namespace I though you allready got it in a dll...

You can compile the classes into an assembly (.dll) by creating a new "Class library" project and copy all .cs files into that project. Then you can reference that assembly in every project where you need the classes.

What do you mean by that? Have all classes just the same namespace or do you also compile them to a library?
If these classes are available as source files then simply add them to your project by right-clicking on the project folder and selecting "Add existing item..". If they are compiled to a library, you have to reference this library as said by the other poster.
Anyway, if the classes are declared in the namespace "CsGL.Basecode" you cannot access them via "System.CsGL.Basecode", cause your namespace won't be added to the System namespace.
