Why do you want to put this into an UserControl?
It would be much easier to simply extend the TextBox class.
|

I did this because I like to create a custom control that is all-in-one, meaning I will be adding my custom dropdown box, add a date dropdown, add some buttons to it and anything that I can think of. My problem is if I compile my control then use it on VB.NET environment I can't access the event of my textbox becuase all event that is showing are usercontrol event(unless I make my own custom event which render the usercontrol event useless but still showing in my control's event). So what I want is when I run my VB project using my custom control then I press a key on my custom control what I want is the keypress event of the control to fire up. So is there any way to expose the events of the textbox instead of the event of the user control without making custom event just to send all the events of the textbox to the user? And is there anyway to hide some events in the usercontrol?
Thanks.

Yeah, I thought you do something like this. Just wanted to be sure 
To expose events of your TextBox without making custom events, you could subscribe your Control to the TextBox events and inside the event handler raise the appropiate event of your Control. If you want to expose some specific TextBox events you will have to declare custom events.
<br />
class Custom : UserControl<br />
{<br />
TextBox textBox1;<br />
<br />
public Custom()<br />
{<br />
textBox1 = new TextBox();<br />
textBox.TextChanged += new System.EventHandler(Custom_TextChanged);<br />
}<br />
<br />
void Custom_TextChanged(object sender, System.EventArgs e)<br />
{<br />
this.OnTextChanged(EventArgs.Empty);<br />
}<br />
}<br />
To hide some events of your UserControl you have the redeclare them with a stricter access modifier like private or protected.
<br />
private new event System.EventHandler SizeChanged;<br />
Hope this helps!

Thanks Stefan you've been a great help. Now I can continue coding my controls.

My pleasure!

Stefan has a point, but if you're building a composite control, then you either need to add events to the UserControl, which would handle the events of the TextBox. The handlers for the various TextBox events fire the events on the UserControl (either overriding existing events like TextChanged or making new events like TextBoxTextchanged).

Hi all,
How to use a textbox control along with a calender control in asp.net codebehind is C#.
onclick of the calender's particular date the day/month/year should be put in the 3 textbox respectively?.
How to code for this. On server side or client side.
because i want that dates comparison also.
thanks in advance

hi,
Let me first clarify what I have understood from your requirement...
You have a calender control on the web page and 3 textboxes.
When the user selects a date the day month and year component should get displayed in the 3 text boxes...
If this is so... then herez the code...
private void CalMain_SelectionChanged(object sender, System.EventArgs e)
{
DateTime selDate = ((Calendar)sender).SelectedDate;
txt1.Text = selDate.Day.ToString();
txt2.Text = selDate.Month.ToString();
txt3.Text = selDate.Year.ToString();
}
Note : This code is server side.
regards,
Aryadip.
Cheers !! and have a Funky day !!

Hello, could anyone share info on how to reduce the memory usage of a .NET windows application. I noticed that my application that was written in C# consumes 10 mb of page files which I think it is kind a bloaty.
Any areas which need to be targeted for optimization for .NET application?
thank you.

I'm not sure if you've already done this, but there's an option to "Optomize code" in C# Apps. You can find it in Project Properties -> Build Options

yes, it has been done cause I am building it in release mode.

Did you update your bio. I've seen your bio before, but it said you were from the states.

There is no way to reduce that footprint and your app really isn't using that much memory. If you look at the working set for the app, you'll see that it is considerably smaller than what you see allocated in TaskManager. It is page space that is, call it reserved, for your app, but not in use. This space can be freed at any time and used for other processes by the Garbage Collector and/or the page manager in Windows.

You should definitely read the newest Patterns and Practices book, Improving .NET Application Performance and Scalability[^]. It's good for any newbie, intermediate, or advanced developer.
Specifically for what I wanted to mention, you should take a look at Finalize and Dispose Explained[^] and the following 2 or 3 sections in Chapter 5 of that book.
Disposing objects is a big advantage. Since almost all Windows Forms controls (and many other classes in the .NET FCL) encapsulate native functions and resources - called unmanaged resources because they're not managed by the runtime Garbage Collector (GC) - they need to be disposed. The controls in Windows Forms will take care of this for you since they follow the common pattern, but disposing them when you're done will improve performance since the object is freed and the GC won't need to collect it later.
This is especially important if you use Form.ShowDialog. If you read the documentation for ShowDialog, you'll see that it says you must dispose it. This has something to do, IIRC, with the message pump created to handle the dialog (though this isn't necessary for Show). A good way to make sure this - and other objects - are disposed - even in case of error - is to use the using statement like so:
using (MyForm form = new MyForm())
form.ShowDialog(); Boxing and unboxing is also a big hit on performance. Value types - like the primatives, enums, and structs - are allocated on the stack. When you treat them as an Object, they are boxed. When you cast that Object back to a value type, it is unboxed. This is very detrimental. For now, all you can do is suffer or rewrite many of the common classes like ArrayList that many use to store value types. With .NET 2.0, C# (and other languages) are gaining support for generics (templates in C/C++). This will greatly improve performance since a value type would be stored and accessed as a value type with boxing and unboxing.
The Patterns and Practices book has a lot more information I'm sure you'll find useful.

i build a C/S based TCP connection.
Server send to Client data 20 times in a loop like this:
for(i=0;i<20;i++)
SocketServer.Send(data);
while Client receive data from Server 20 times in a loop :
for(i=0;i<20;i++)
SocketClient.Receive(data);
for some reason, at the 10th step, Client has an error and couldnt receive lots of data behind.
In TCP connection, the data after 10th step will be stored in System Chache. But i dont need them further. How to discard them and Empty System Chache?
