Hi all,
I already convert a C++ project to C# project. It's fine and working ok.
On C++ I use DWORD data type. But in C# for that I used just a int value. Is that ok. Is there compatible data type which I can use for my project.
Thanks. 
I appreciate your help all the time...

Are you having an issue, or are you just worried in general ? long is bigger than int in C#.

Actually I worried this because it related with registry. So new value type should be compatible with registry data type REG_DWORD

UInt32 or Int32 are equivalent to DWORD in c#.

Seems it is fine. Thanks a lot.
At the same time I found one thing. bool type variable gives the same output as DWORD. Do you guys know about it?
I appreciate your help all the time...

Use DrawToBitmap method of control to draw image of control on a bitmap object.
After this you may use a PrintDocument and PrintPreviewControl and you may draw this bitmap image on PrintDocument using PrintPage event.

Hi all,
In the form load of a text box, I want to display a value from the registry. So I try this in InitializeComponent() as follows.
namespace ServerStarter
{
public class Form1 : System.Windows.Forms.Form
{
private RegistryKey regKey =
Registry.LocalMachine.OpenSubKey( "SOFTWARE\\Test\\MyTest", true );
private void InitializeComponent()
{
this.textBox1.Text = regKey.GetValue("server");
}
}
}
Here server is one of the value in my regKey registry sub key. This code gives an error
F:\Projects\FocusGroupServer\ServerStarter\Form1.cs(467): Cannot
implicitly convert type 'object' to 'string'
can you tell me where I'm going wrong.
Thanks.
I appreciate your help all the time...

Ok, I found where I'm going wrong with my code. I have to use them as a string.
So,
this.textBox1.Text = regKey.GetValue("server").ToString();
This works for me fine, in form load the correct value is displayed on the text box. But gives a warning says
The variable 'regKey' is either undeclared or was never assigned.
And also I found one funny thing. Suddenly after doing some design modification, the textBox1 text set to empty as
this.textBox1.Text = "";
This is happened automatically. Why is that. In compile time I don't get any error at all. I'm really worried about it.... 
I appreciate your help all the time...

hello friend,
u may combine your code and donot need to store value on a variable like regkey. Like this :
TextBox1.Text = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Test\\MyTest", true).GetValue("server").ToString();
OK.
Reply.
Best of Luck.

Initially I though about it, but not tested. Because say I put more texboxes later, say all together there is 5 boxes. So I have open a same registry key 5 time. Is that ok.
After the line
dipak.dipak wrote: TextBox1.Text = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Test\\MyTest", true).GetValue("server").ToString();
I can't do,
Registry.LocalMachine.OpenSubKey("SOFTWARE\\Test\\MyTest", true).Close();
because such logics are not allowed in InitializeComponent(), isn't it?
I appreciate your help all the time...

Yeah, u r right. If u didnot initialize that component than why r u going to close?
As u said : "put more texboxes later, say all together there is 5 boxes. So I have open a same registry key 5 time."
than u may retrive the registry value once and store in a String variable and set text of other textboxes.
String strRegVal = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Test\\MyTest", true).GetValue("server").ToString();
TextBox1.Text = strRegVal;
TextBox2.Text = strRegVal;
TextBox3.Text = strRegVal;
TextBox4.Text = strRegVal;
TextBox5.Text = strRegVal;
Is it OK as u want?
Best of Luck.

Yes it's true. But I'm still wired on it pal. Say I want to display five different registry values, that mean I have five different names. So I have to use five sub keys in your way. Isn't it?
By the way I tried one way. As usual write a separate function to set the initial values on to text boxes and call that function in form load. What you think of it. There is no any warnings either.
I appreciate your help all the time...

You really shouldn't do this in the InitializeComponent method as it's likely to get erased. It's safe to hardcode a value in there i.e. this.textBox1.Text = "Initial Text";.
When you modify your form in the designer, let's say you add a text box, the VS rewrites the InitializeComponent adding your new text box to it and setting some basic property values. It does the same anytime you modify a property in the designer. When it does this, the whole method is rewritten and any changes you made will most likely get erased in the process.
Before the InitializeComponent method there is this to warn you:
#region Windows Form Designer generated code
You should put your code either in the constructor after the call to InitializeComponent, or better still, in a seperate method to be called afterwards.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
OtherInitializations();
}
private void OtherInitializations()
{
this.textBox1.Text = regKey.GetValue("server").ToString();
}
}

Yes,
That's what I have done on my last post. As far as I feel, I can edit only the initial properties of controls, without using the Properties window.
Only I can't put any logic there. Isn't it.
I appreciate your help all the time...

Yes, that's correct. Any properties that can be set in the properties window AND the values that can be entered there will be OK. Anything else you should do in your own method or in the constructor AFTER InitializeComponent

I was looking for an application that will monitor how much traffic I send and receive via the internet only.
Most of the programs I looked at had far more features than I need (though NetLimiter was very nice). I thought this might be a good opportunity to try writing my own.
However I am not really sure where to start.
What classes would let me look at the internet traffic and record the size of each inbound/outbound packet?
I have heard mention of something called winPcap, but not really sure how to use it.
Any pointers appreciated...
