Hi,
you can store anything you like in an ArrayList or any other kind of collection (Hashtable, SortedList, ...).
you can store all kinds of objects with a common base type (such as Control) in a List of that type, or any other kind of collection capable of holding your base type (Dictionary, ...).
You probably don't have to create a new collection since each Control (and hence each Form) already has a collection holding ALL its Controls.
Example: if you want to do something to all the Buttons on myForm, this would be sufficient:
foreach(Control c in myForm.Controls) {
Button btn=c as Button;
if (btn!=null) {
btn.PerformClick();
}
}
Warning: a foreach on an enumerator will not allow you to modify the collection, so the above loop would not allow you to add or remove buttons; you would need a for or while loop for that.

Don't forget that the form also may have containers (panels, group boxes etc) which may have buttons in them. You will need a recursive structure to get ALL the buttons on a form.

Its better if you use Hashtable cause here in key you can also save the ID of that button.

You don't need to do that because the Name property is the ID. Since it's already in the control, no need to store it outside of its current context.

They're already in a list (look at the controls property). Don't forget that a container control (like a panel or group box) will probably have child controls, and will therefore have their own list. It's like a singly linked list.

Hi, we are doing a project using C# and would like to release it as an OpenSource software. However, we are using a few DLL files which ofcourse we have made and are willing to share the source code for further development. Under such circumstances, is it violating the Open Source license?
Thanks,
Abhishek.

If its your code, then you can't break your own license  If you want to share the source for them as well, go for it.
It also depends on what Open Source license you choose. Have a read on wikipedia about what license is suitable for your goals.

I prefer to get DLLs along with the source code.
I think an open-source project should allow people to read and compile the code, but not require them to.
I don't like having to build other peoples' code, though at least it's easier with .net (due to limited operating system and compiler support  ).
One of my worst experiences was trying to build an OpenVMS version of a Perl module (a driver for RDB); I never got it to compile.
My best experience was compiling the MySQL ADO.net connector, the only problem is all the warnings about Obsolete methods.

Hello
I want create a file fox (*.dbf) which has 3 fields (ID, NAME, MOBILE). Then I need insert data to this file. Example:
1, Mr Join, 0912555666
2, Ms Angela, 0123666777
----------------------------------------
You can help me? There are examples as possible. Thank you very much!

No idea what you are asking. Please clarify.

Why DBF, this format is no longer used in any applications that I know of (possible exception is Foxpro). I suggest you look into another database, Access or SQL Express and there are a couple of others out there that will be a better option than DBF.
You cannot "write" to a .DBF file using filestream, you have to create a connection to the file, you may be able to use the Jet engine, try connectionstrings.com
You could also use XML for small data sets.

I download a sample file in this site http://msdn.microsoft.com/en-us/library/bb676897.aspx
I'd like to use "Windows Live ID Client Sample" with delphi 2007 or delphi7.
I tried to import " Microsoft.WindowsLive.Id.Client.dll" but Delphi is just made connect functions.
When I show with VS2008, I can use my features function.
How can I use this dll or not?
Thank you

If you're asking how to use the dll in Delphi, then I guess you've got the wrong forum.
Try to ask the same question on some Delphi for .Net forums
Regards,
Lev

If the Delphi you're using doesn't target the .NET Framework, you'll need to write a COM-exposed wrapper, using C# or VB.NET or some other .NET targeted language, around the classes and methods you want to use in this .DLL so Delphi can use it.

Suppose I have a long byte that can represent some GBs and I want to read it for example as:
2 GB, 11 MB and 25 KB
I'm not interested in dividing it by (1024^3) for GB as an example to see 2.02 GB, I want to know how much is that 0.02 GB in MBs and KBs
Please help!
All generalizations are wrong, including this one!

Use the Math.Floor function for this. 2.02 - Math.Floor(2.02) is .02. You can then work out what that .02 is in MB, and do the same to get a remained for KB.
