Hi
According to my knowledge when you want use any event of custom control,you need to assign local handler to that event ;
eg.
customcontrol1.MouseMoveEx+=OnMouseMoveEx;
where OnMouseMoveEx and customcontrol1 are both in one class.
I think, you will get how to do it.
Regards,
Amar

thanks
when in designer mode, double click on MouseMoveEx event in events window, it will be genererated automatically :
customcontrol1.MouseMoveEx+=OnMouseMoveEx;
but i think that the event handler doesn't know what time fire this event.

Hi,
Can you describe your coding flow shortly ?
Eg. class customcontrol
{
//code of event handler
}
class where_you_use_customcontrol
{
//code of event handler
}
and when you want to raise that event.
So my view become clear.
Regards,
Amar

Hi.
I want to place a Combo Box in my Windows Form where all the CultureInfo language selection names will appears. For example, when I make a customer control, I created a property of type CultureInfo and then I found that the Visual Studio Property Editor shows the Language lists in a combobox in property window automatically. I want to get this benefit in my Windows form. Would you please give me the right direction ~!
Thanks

I need to put some listbox selected items in to a string array.
My code:
string [] deleted_dictionarys;
for (int i = 0; i < this.listBox_Delete1.SelectedItems.Count; i++)
{
this.deleted_dictionarys[i] = this.listBox_Delete1.SelectedItems[i].ToString();
}
I don't have sintax errors but i'm getting a NullReferenceException.
How can i resolve it.

You declare your array but don't instantiate it. You need to do something like this:
string[] deleted_dictionarys = new string[numberofitems];

here is easy and short way
string[] deleted_dictionarys = new string[listBox_Delete1.SelectedItems.Count];
listBox_Delete1.SelectedItems.CopyTo(deleted_dictionarys, 0);

Hello,
I am wondering if it is really not possible to obfuscate my .NET code by hiding the class names and method names !! I am using XenoCode PostBuild to obfuscate but when I see the decompiled code using Reflector, I can see that only variable names are obfuscated but the Class Name and method names are very clear. For example, - SendKeys.Send("{BS}"); - is clearly visible. My project is such a project that, even one line like this line would reveal my business secret to my competetors and thats why I am worried, if not hiding the Class Name and Method is .NET's limitation or my obfuscator's limitation. Would you please guide me !
Thanks.

What secrets? What have you done that's so revolutionary? Have you reinvented the Internet with go-faster stripes?
If the most groundbreaking aspect of your application is its ability to send keystrokes to the active window, I doubt your 'competetors' (sic) will be worrying themselves too much.

Hi,
Thank you very much for pointing my ignorance, actually I gave an example of a snippet like
SendKeys("{BS}"), of course it was not my real snippet that what I was worrying about. I placed this question here to learn about the professional way of obfuscation technique that a .NET GURU can suggest. It is not that I invented something like what you said, but it could be something really matter that I may not want to reveal to my competetors so easily unless they are desparate to break my code, I hope I made my question clear, ain't I.
Again, thank you very much for replying me.

If you choose to develop in an IL-based language like C#, you will have to accept that someone will a little time and patience will be able to disassemble your application. Obfuscators, even the better commercial variants will only delay this process. If someone is determined enough, they will be able to obtain your source code and 'business secrets'. If this is an absolute priority, maybe C# isn't the right language to use and you would be better served by moving to a language that compiles to native code like C++. Before you do this though, consider whether your source code really contains anything that constitutes a commercial advantage. Are you doing anything that's particularly groundbreaking? If not, your source code probably doesn't contain anything that your competitiors couldn't figure out for themselves.

Thank you Sir, this answer helped me a lot.
Actually my target is to learn software development business using the benefits of .NET. So, I was wondering, if the source code is open then what will be the motive for a developer to participate in e-Commerce !! Now I have understood the reality and got my answer.

Considering the amount of effort the computer gaming industry and Microsoft put in to stop their products being copied - and how that manages to fail every single time, I'd suggest you don't have much hope.
If your idea is unique and revolutionary, then patent it and enjoy the legal protection.
Without the legal protection, if your technique is really worth lots of money (which I sincerely doubt) then your competitors will definitely find it worth paying a .Net guru to reverse engineer your application. In this case an obfuscator / coding in C++ / executable packers will only make it a little more expensive for your competitors to find out your "IP".

Just change the names to meaningless gibberish.
Way back when I was first learning Pascal there was a program I wrote using only nonsense words for variable names.

Clip is just a property, so get and store its value before you alter it so you can restore it afterwards.

Probably, but you would have to use the Windows API and listen to/intercept/block system keypresses.
I wouldn't recommend this though as the user needs a way to switch to another task or close your program if something goes wrong. Keeping the mouse within the bounds of your app when it has focus should be more than enough. Anything else (and maybe even just this) would be hated by end users.

refrence for learn.
First of all, give your posts more meaningful names. 'Plz help me' doesn't give anyone any idea what your problem is. Read the forum guidelines.
Secondly, if you want to learn database programming, buy a book. Amazon[^] provides a list of suggested titles.
