Can you please post the relevant piece of code, pointing out what's going wrong?

I wrote:
Class p = new Class();
ArrayList a = new ArrayList();
a.Add(p);
now I want to call function of on eof the objects
in the array
how I call it?
a[0].?

It is quite straighforward, you have only to remember that, since the ArrayList operator [] returns an Object, then you have to cast it to the proper type, for instance (assuming that MyClass has a method Version() returning a string):
MyClass p = new MyClass();
ArrayList a = new ArrayList();
a.Add(p);
string sVersion =((MyClass)a[0]).Version();
MessageBox.Show(sVersion);
hope that helps

but if I want to call method Version for every object
in the array?
I tried to do :
a[0].Version;
but it's not working.why?

How does versioning work and how do I set up my project to have a version no.?

The most famous project to help u with versioning is CVS, well am using it with Mono-Develop over Linux i don't if there is a version for Windows, but i guess there is a version for Windows

I believe he was asking versioning the assemblies in a project not version CONTROL

You need to set the attributes below. In a non-web project these, and others, are included in AssemblyInfo file in the properties folder of the project.
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

Hello
I´ve got two datagrids. The first one, "a", can use scroll bars when there is more rows that the rows that can be show.
The second one that is not possible. The scroll bar is not shown.
What can i do to show the scroll bar?
Best regards

I am working on a multiuser application that has a DataSet. To manage deleted rows in the multiuser setting, I have added a Deleted column to all tables and my application is not supposed to show these rows to the users. So each DataViewSetting in my DataViewManager has a rowfilter ("Deleted = 0").
I found a databound treeview on the net which is way better than the one I made, where I traversed the actual rows and relations. The one I found use CurrencyManager and position to traverse the tables and add nodes to the tree.
My problem is that this algoritm does show the "deleted" rows - I dont think the DataViewSettings gets involved.
I need to add that my application also has a panel that shows childrelations in datagrids - using the dataviewmanager. This works.
Does any of you have any idea how to make this work? All the examples on databound treeviews I've seen on the net operate directly at the dataset, not on the dataviewmanager.
I'll be very grateful for any help. Oh.. and it's a bit urgent, too

Hi.
what do u mean ? what your header contains ?
you can put your header in frame or in a table .
you can insert frameset from the properties of the document and put a new frameset in your page.
or you can create a table in your page and place your header in the row or column of the table.

I'm trying to create a very simple Control that will host a collection of various objects. This is all the code amounts to:
using System;<br />
using System.Collections;<br />
using System.Collections.Generic;<br />
using System.Collections.ObjectModel;<br />
using System.Text;<br />
using System.ComponentModel.Design;<br />
using System.ComponentModel;<br />
using System.Drawing.Design;<br />
using System.ComponentModel.Design.Serialization;<br />
<br />
namespace Test<br />
{<br />
[TypeConverter(typeof(ItemTypeConverter<BaseItem>))]<br />
public class BaseItem<br />
{<br />
private string _itemName = "";<br />
<br />
public string ItemName<br />
{<br />
get { return this._itemName; }<br />
set { this._itemName = value; }<br />
}<br />
}<br />
<br />
[TypeConverter(typeof(ItemTypeConverter<IntItem>))]<br />
public class IntItem : BaseItem<br />
{<br />
private int _value = 0;<br />
<br />
public int Value<br />
{<br />
get { return this._value; }<br />
set { this._value = value; }<br />
}<br />
}<br />
<br />
[TypeConverter(typeof(ItemTypeConverter<StringItem>))]<br />
public class StringItem : BaseItem<br />
{<br />
private string _value = "";<br />
<br />
public string Value<br />
{<br />
get { return this._value; }<br />
set { this._value = value; }<br />
}<br />
}<br />
<br />
public class ItemTypeConverter<T> : ExpandableObjectConverter<br />
{<br />
public ItemTypeConverter()<br />
: base()<br />
{<br />
<br />
}<br />
<br />
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)<br />
{<br />
if (destinationType == typeof(InstanceDescriptor))<br />
return true;<br />
else<br />
return base.CanConvertTo(context, destinationType);<br />
}<br />
<br />
public override object ConvertTo(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value, Type destinationType)<br />
{<br />
if (destinationType == typeof(InstanceDescriptor))<br />
return new InstanceDescriptor(typeof(T).GetConstructor(new Type[0]), null, false);<br />
else<br />
return base.ConvertTo(context, culture, value, destinationType);<br />
}<br />
}<br />
<br />
[TypeConverter(typeof(ItemTypeConverter<ItemCollection2>))]<br />
public class ItemCollection2 : CollectionBase<br />
{<br />
internal ItemCollection2()<br />
{<br />
}<br />
<br />
public BaseItem Add(BaseItem item)<br />
{<br />
this.InnerList.Add(item);<br />
return item;<br />
}<br />
<br />
public void Remove(BaseItem item)<br />
{<br />
this.InnerList.Remove(item);<br />
}<br />
<br />
public bool Contains(BaseItem item)<br />
{<br />
return this.InnerList.Contains(item);<br />
}<br />
<br />
public BaseItem this[int i]<br />
{<br />
get { return (BaseItem)this.InnerList[i]; }<br />
}<br />
}<br />
<br />
public class ItemCollectionEditor : CollectionEditor<br />
{<br />
private static Type[] types;<br />
<br />
public ItemCollectionEditor(Type type)<br />
: base(type)<br />
{<br />
types = new Type[] { typeof(IntItem), typeof(StringItem) };<br />
}<br />
<br />
protected override Type[] CreateNewItemTypes()<br />
{<br />
return types;<br />
}<br />
}<br />
<br />
public class ItemCollectionHostControl : System.Windows.Forms.Control<br />
{<br />
private ItemCollection2 _items;<br />
<br />
public ItemCollectionHostControl()<br />
{<br />
this._items = new ItemCollection2();<br />
}<br />
<br />
[Editor(typeof(ItemCollectionEditor), typeof(UITypeEditor)),<br />
DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]<br />
public ItemCollection2 Items<br />
{<br />
get { return this._items; }<br />
}<br />
}<br />
}
However, whenever I add items to the control, the Designer does not generate any code for them. As a result, whenever I build the project, the collection items are lost.
Can anyone see what I'm doing wrong? This is merely an example of something more complicated that I'm trying to achieve by the way - this problem is proving to be a major stumbling block. 
Thanks in advance.

Hi Somebody has asked me a question in interview.
we have two classes Class1 and Class2
public class Class1
{
private Class2 obj;
public void method1()
{
obj = new Class2();
}
public void method2()
{
obj.method1();
}
}
public class Class2
{
public Class2()
{
GC.SuppressFinalize(this); }
public void method1()
{
}
}
Now in GUI form: onbutton_Click I write the follwing code:
Class1 class1 = new Class1();
class1.method1();
class1.method2();
After the above code is finished, WILL Garabage collector collect objects of Class1 and Class2 or not?

Ashwani,
Of course the easy answer is YES...the garbage collector will eventually get everything sooner or later(even if it has to wait for a reboot  ). The better question, and the one they probably intended was, "Are the objects of Class1 and Class2 marked for GC or not?". The answer is still yes.
I assume the bold on the GC.SuppressFinalize(this); line is primarily what they are asking about. That line HAS NO MEANING WHATSOEVER IN THIS CONTEXT. That line is meant to short circuit the running of a destructor/finalizer for a class. Since neither of the classes has a destructor defined, the line of code does nothing.
In this case both classes will be marked for GC at the end of the click event code.
