Thanks gareth111,
I have read through the article, looks great and answered most of my questions. One question which is not answered is what is the relationship between Finalize method and destructor?
Finalize will call destructor or vice versa? Or no relationship? GC will call Finalize, but I am not sure whether GC will call destructor as well?
regards,
George

You use the windows media player control, or managed direct show ( which is in the platform SDK nowadays ) to play video files. A cursory search of the web would give you tons of samples

Hello everyone,
1.
C# has integer types, int, int32, int64 and long. In my understanding, int32 is always 32-bit, int64 and long are always 64-bit.
My understanding correct?
2.
How about int? Is it 32-bit or 64-bit or depends on how we build application (build as 32-bit? build as 64-bit or any CPU?)
thanks in advance,
George

Yes, Int32 represents a 32 bit signed integer, and int64 a 64 bit signed integer.

It represents 32bit by default.

Use a foreach loop on the items in your listbox and add the ones that are not selected to a List<string> (provided you're using .NET 2.0 and above)

Hi all,
In my application i have 5 forms. I would like to store some value in global varialble which can access by any forms in my app.I have try to create a get/set class and i declare a public object in form let said form A. But i can't access the object in form B. My example coding as below:
Class GetSet:
private String _name;<br />
public String name<br />
{<br />
get{return _name;}<br />
set{_name = value;}<br />
}
FormA:
public partial class FrmA : Form<br />
{<br />
GetSet gs;<br />
public FrmMain()<br />
{<br />
gs = new GetSet();<br />
gs.name = "cocoon";<br />
}<br />
<br />
}
FormB:
public partial class FrmB : Form<br />
{<br />
GetSet gs;<br />
public FrmMain()<br />
{<br />
console.write(gs.name);<br />
}<br />
<br />
}
Can anyone guide me to slove this out.
thanks in advance

You have to rethink your design.

You can't. However, you can create a static class which is quite similar to what you are asking for. There are plenty of examples on Google.

The way to do this, is to use delegates, or create a class with static properties. If you thought that FrmB would do anything but crash, or had any chance of seeing hte value 'cocoon', you need to do some serious reading on OO, because you've misunderstood quite a bit.

Hi Vikram and Christian,

Thanks in advance.

You can use singleton class object. It will help in state maintainance in the application.

Hi,
I'm working on an tiny application with an MySql Server and 2 buttons and 2 textbox,
The idea is that when i fill in the 2 textbox and press one of the buttons i add an entry to my Database(located on an external host)
i've been reading this article:
http://www.codeproject.com/KB/database/MySQLCsharp.aspx[^
But i'm still not clear on how to get it done.
I could use any advise/code snippets.
Thanks in advance

That article looks pretty good to me, what exactly are you struggling with? I presume you've downloaded the .NET connector and included it in your project?

Yes i have,
and now when i try to use my DataGridView and use the MySql (external located) i wont connect to it,
it always gives error message that it cannot connect to the server/database
|

OK, well it would help a lot if you could post some relevant code snippets, specifically the section where you create your MySqlConnection object, attempt to connect etc.

If you have a client tool of mySql, did you try connecting using that? This is to verify if the server is up and running, accepting connections from the specified hosts and there is no intermediate firewall software peeking into and 'eating away' the packets.
If your system has a Php, then you can try using PhpMyAdmin (http://phpmyadmin.sourceforge.net/[^]). It is a web-based frontend for MySQL database.

If your MySQL server is running on a remote machine, you will have some permission issues. By default MySQL uses port 3306 to listen. You need to ask your server providers to change the firewall settings which allows connections from outside to this port. You may try to install MySQL GUI tools and connect to the server. This will give you exact error message.
