Alexandru,
a similar construct to friend is the internal keyword, which allows access from within the same assembly, but not from outside.

Thanks for the reply.
However the protected members I wanted to access were some WebControls that the designer created for me in a ASP.NET page. I didn't want to manually change the access level for those object so I decided to redesign my application.
Best regards,

I am creating a custom control which inherits from combobox class.
Now, I want to prevent some events from being occured at special times, for example I want my combobox, when is in droped down state, not responsing to click events, to prevent it from getting back to its default state. I think it may be done throughout overriding OnClick eventhandler or some better one to handle.
Please help me! 
Regards

Correct, more specifically override OnClick and in the cases where you don't want the Click event to fire just don't call base.OnClick(). Then when you want the Click event to fire ensure you call base.OnClick().

Have you any suggestion exactly about this :
"I want my combobox, when is in droped down state, not responsing to events, to prevent it from getting back to its default state"
The OnClick is not proper for this situation.

Is there way to make int i = (int)3.6; give a rounded as opposed to floored result? Some global setting?

Right click on the 'References' tree node in the project view. Goto 'Add Reference', then look down the .NET list for System.EnterpriseServices, click select then OK.
You can now use the namespace in your code. Howzzat!

http://www.codeproject.com/cs/menu/dockingcontrol.asp?target=dockstyle%7Csize
discusses adding controls to a form using AddRange in a specific order.
(The problem)
I am trying to do the following, dynamically in a form constructor:
1. Add TabControl to form. TabControl is set to DockStyle=Fill
2. Add TabPage to TabControl. (Automatically fills TabControl)
3. Add Panel to TabControl.
Problem: I need to access the size of the TabPage AFTER the DockStyle=Fill has come into effect. This is to precisely position the panel in a location on the TabPage.
But during initialization, the only Width/Size I can get from TabPage, is the DefaultSize (100 x 200)
Is there any command I can call to force the TabControl to fill the parent form, then retrieve the new size/width of the contained TabPage after the fill?
Thanks for suggestions.

Use Load or Resize event of controls (panel etc)
Hi,
AW

Hi
Thanks for reply. However it still seems no clearer. I also found a Layout event.
The question is: At what time, during the instantiation of a control, can we be certain that the DockStyle Fill has been applied to the controls width/height. And therefore, at that point, we can be certain to rely on those as containing the final values, and not the DefaultSize values?
MSDN seems unclear on this in any of the event descriptions.
Cheers

I have a Treeview/Listview pair in a Windows Form that behaves like Windows Explorer, displaying folders and files on my machine... both controls have checkboxes for each entry so I can keep track of what's been selected.
Aside from maintaining a current global TreeViewEventArgs object, is there a good way to update the Treeview when you click the listview and receive the listview_AfterCheck event? I want to be able to have the parent (folder) node in the treeview become "checked" when I "check" a file in the list view... wondering if the .NET framwork provides some sort of communication mechanism for this..???
thanks.

Since a form hosts both the treeview and the listview, I would override both OnBeforeCheck event handlers, and provide a default implementation to them, calling a unique method at the form level. This method in turn Invokes Check() methods exposed by tree nodes, and list nodes.
Nothing really new to talk about, that's much like delegating the application logic to a control manager.

Interesting, I guess I've never overridden a windows-fired event... how do you get windows to fire the overridden vs. the non-overridden event?
thanks.

Silly question probably, but...Whats the easiest way to communicate from a child Window to a parent window. For example, when the app starts, I want a login form to popup. When entered, that data needs to be available throughout the app. Currently I am using the "OnMdiChildActivate" event on the parent window which works, but it seems as if there should be a better way.

You could do this in a couple of ways.
If you are in full control of the form that is poping up, you can get the required information by capturing the OnClosing event of the logon form, add the event handler in your MDI parent's load event when you open the mdi child:
LogonForm f = new LogonForm();
f.MdiParent = this;
f.OnClosing += new EventHandler(this.Form1_Closing);
Having done this, write code along these lines to capture properties from the closing logon form:
private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
LogonForm f = (LogonForm)sender;
string Uname = f.Username;
string Pword = f.Password;
}
obviously you'll need to set up properties such as Username & Password in you logon form that are public.
An other way may be to pass up a custom Logon class from the Parent to the child by reference, you can then populate it from the logon form and the information will be available to the parent.
Let me know if you'd like me to elaborate on either of these methods.

Thanks..thats an interesting idea. I actually did it a different way by when the user logs on successfully, having the child window (logon form) populate some public properties of the parent window. I like the idea of having the parent window handle events of the login window however.

I have written a simple web service, well it's kind of complexe, but it is working GREAT on my local machine. I can call it via the URL and it does EXACTLY what I want it to do (http://localhost/webServiceName/WebService.asmx/theWebMethod?var1=stingVar1&var2=stringVar2....). So now I want to put it out on my production server. So I follow all the steps that are laid out in this example.
When I run it, I get this error:
==========================================
Server Error in '/agnWmEventTools' Application.

I know this has to be something simple, right??  The only difference is in the systems running it. When I first put this on, I got an MDAC issue so I upgraded the MDAC on the server running .Net and that error went away and now I get this error above.
Thanks,

Well nobody answered my question. 
However, not all is lost. In digging and doing some reading it seems that .Net framework version 1.1 that these two little lines are commented out
<add name="HttpPost"/>
and
<add name="HttpGet"/> in the machine.config file. Once I un-commented those and saved the file it worked like a charm.
I am just posting this in the hopes that somebody else might learn something from it too. If this was already common knowledge, sorry about posting something so dumb. 
Thanks,
Bill K.

I'm adding objects of a custom class to a check list box and when I call the Add () method of the check list box the string it adds is simply namespace.classname. I don't want it to add this I want it to add a string variable that is declared in the class. I tried overriding the ToString () method because I thought it might be calling that, but it still added the same thing. Does anyone know what method I can override so that it adds the string I want.
Thanks again.

Why don't you add that string to the list box instead of adding the object that contains it?
|
|
|
|
|
At first I didn't want to do that becasue I was going to add the whole oject to the list box. I've decided to go a different route since. Now I'm doing exactly that (simply adding the string I wanted) I'm adding the objects into an ArrayList.
Thanks

If you did want to go back to your original idea... derive your object from ListViewItem (im doing it with tree's so you might need to check that), and then set its text (no need to overide) to whatever text you want to appear in the list/tree. Then when you add it to the list it will have the exact text that you want.
Hope that helps any one else trying something like this!
On a similary note... Does anyone know how i can add the same TreeViewItem to 2 different TreeView's without having to clone it?
