I have a user control that work as a parent and contains a collection that keep track of objects or child controls ..
I need a way to fire an event that is handeled within the user control or do some action "refresh for example" when a new object or Control is added to this Collection "ParentControl.Childs.Add(NewChild)"
Thanks in advance

Hello,
Maybe you could call a recursive methode in your usercontrols constructor, which goes threw the Controls Collection and links to all "ControlAdded" events.
<code>//constructor code
this.MyRecursiveMethode(this.Controls)
private void MyRecursiveMethode(ControlsCollection cc)
{
if(cc!=null)
{
foreach(Control c in cc)
{
//link to the event
c.ControlAdded += new System.Windows.Forms.ControlEventHandler(this.Control_Added);
//Call the method again and again and ... , as long as neccessary
MyRecursiveMethode(c.Controls);
}
}
}
private void Control_Added(object sender, System.Windows.Forms.ControlEventArgs e)
{
//link the event of the new added Control
e.Control.ControlAdded += new System.Windows.Forms.ControlEventHandler(this.Control_Added);
//here is your code
}</code>
Hope that helps you.
All the best,
Martin

thnks so much martin for your wonderful effort and help ..
i found the way and solution to my problem using the help of your thought specially the use of ControlAdded event .. i wired the event to the panel that hosts that ChildControls ..
my 1st idea was to try to hock this event to the System.Collection.Add method itself (i have a collection that keep track of the controls rather than the controls property of the panel)i thought i could respond when a new item or control is added to this collection .
.. but i really couldn't undersatnd the use of recursive method .. any way thanks again for your help Martin

Hello everyone,
I am using C# on a Pocket PC 2003 project based on .Net Compact Framework of Visual Studio 2005. I want to re-draw some controls of a Form (Window) at a regular interval (for example, change the title of some Label or something similar). The issues I met with are,
1. My application has several Forms/Windows. How to check whether the specific Form/Window (which I want to re-draw) is active? If the Form/Window is not active, I think I should not re-draw the Form/Window. Am I correct? Or, whether or not the Form/Window is active, I should always re-draw the Form/Window?
2. Any code samples specific for C# of .Net Compact Framework?
thanks in advance,
George

how can i convert utf-8 encoding text file into ascii encoding??
streamwrite write the text file in utf-8 encodinf the streamreader read it as utf-8 but if i want to deal with the file as ascii what to do?
|

|

The StreamReader and StreamWriter only uses UTF-8 as default if you don't specify an encoding when you create them.

Hi
I've recently started with VS 2005 using C# (Windows Forms) and have encountered a problem.
I added a reference from Solution Explorer to the System.Drawing assembly as I thought I would need this assembly. Once I'd added it I realised that it was some GDI stuff that I didn't actually need, so removed before doing anything further, by right clicking on System.drawing and selecting remove.
It successfully removed the assembly reference, however unfortunately when the reference was added it seemed to have added a whole lot of code to my file, main.designer.cs (I've only got one form), such as
this.cmdRefresh.location = new System.Drawing.Point(100,308).
This caused compilation errors because the reference is no longer there, and it didn't seem to do any clean up of the code it apparently added.
I did try removing the references manually (despite the warnings not to), but then the positioning of the controls on the form is lost.
I'd be grateful for any help on this and apologies if it's anything obvious.

Windows Forms applications always depend on System.Drawing. The designer always generates "System.Drawing.Point" code, so I'm pretty sure you already had a System.Drawing reference (it's there by default for new Windows Forms projects).

path of files and folders given by user. and every folder and files must kept in an array..
for example:
user gives us C:
and program must fill array like that
arr[0]="c:\Documents and Settings";
arr[1]="c:\Documents and Settings\user_name\";
arr[2]="c:\Documents and Settings\user_name\dekstop";

it goes like that..
i found something in MSDN but it is not actually what i want..
please help..

All you have to do is create the DirectoryInfo[^] instance for the user provided directory and then recursively traverse the file/directory hierarchy, adding the files and directories to a list. The second example in the link I posted shows you how to do that.

How do I truncate a float such that if i have 1.20001, i would want to have 1.2 only for display. How could I achieve this? Thank you very much!
|
|
|
|

If you just want the truncated value as a string, you can use the ToString method on the float instance, like
float f = 1.2001f;
string truncatedFloat = f.ToString("0.0");
If you want that value as a float, you could multiply it by 10x, where x is the number of digits of precision required, cast it to an int and divide by 10x again i.e 1.20001 * 10 = 12.0001 = 12 / 10 = 1.2

works perfectly well. Thanks!

Note that this is not guaranteed to produce the exact value that you expect. A float only has a precision of seven digits, so the result may just as well be something like 1.19999 or 1.20001.
And why not use Math.Round(f, 1)?

Agreed, I missed the fact that the floating point representation could screw up things. But if he already uses tolerance values when checking for equality among floats, this shouldn't matter, right?

You are a bit vague...,
for instance, which data structure did you use?, some sample code?

Well, the first step when you're assigned homework, is to try to do it. That's what it's for. The process of trying, and perhaps failing, is how you learn. You learn nothing if I were to write this code for you.
One you've tried to do your own homework, if you're stuck, post it here, and we're happy to offer advice. I certainly lean towards hints rather than writing the code for you. Otherwise, when I'm a manager, all the people I'm managing will be totally useless, as they've never had to solve a problem for themselves.

Hey guys,
i have site online where my registered users can upload their files. I want to make a desktop application that lets my users upload their files from the application itself. I will be uploading my files using the regular HTTP upload. DO you have any information on where I could get started. I have never made something like this.

hey,
I did a bit research online and found that I'd have to first do an HTTP POST and authenticate myself and then save the logon information as a cookie. Once that is done, I'd have transmit the file in chunks. Is that right? Is there another way? Would I have to do all my HTTP POST and GET through the System.Net.WebClient namespace?
