Thank you very much for your fast reply!
So if B has the ClassB with a method like this:
public class ClassB<br />
{<br />
...<br />
public void MethodB(A.EType myType)<br />
{<br />
...<br />
}<br />
}
and I call it in projectC in this way:
B.ClassB bClass = new B.ClassB();<br />
bClass.MethodB(myNewType);
have I to define necessary myNewType as A.EType (and so I have to reference the projectA in my projectC), or is there a trick to avoid it?

No, you'll have to reference A. Keep in mind that A would be required to load and use B anyway. So if C references B, then you would need to ship A, B, and C in order to use C.
Take care,

Errr...
I only supposed that I partially understand your question.
But, after referred to others' posts, I guess what you were trying to do was merely certain issues of "namespace" that you misunderstood.
In general, a .NET namespace provides a way to encapsulate your classes, delegates, structures, enumerations etc. Meaning, anything you create or implement ought to ultimately exist in namespaces. In such a manner, a project doesn't really suggest an individual object which you can reference to; it merely groups whatever namespaces needed and manipulate the members existing in a pre-defined sequence.
Thus, for your question, you define a public enumeration in project A which subsequently defines "namespace A"; in order to make use of the enumeration, you have to reference the "namespace A" in whatever post projects you create.
Hope it's helpful.

What do you mean by 'wrap'? Does Class2 inherit from Class1? Please try and use the proper terminology when posting questions, otherwise no one will understand what you are talking about.
If you are using inheritance and your enum in Class1 is a public member of this class, you should be able to access it as a member of Class2 from a class that references Class2.

Hi. In my windows form, there is a button control.
When i click on it, just removing the controls from window and adding progressbar dynamically to the window. It working fine and progress bar appearing nice.
At the same time, i am adding Label control to form at runtime only. But it appearing last(i.e after completion of process of progressbar).
Why it wont appear on window first...
in code i added label to form first and then progressbar
can any one give idea reg this.........

Windows execute the code in message queue.
So after the label display you have to use
Application.DoEvents();
Hope this help.

Hi!
Simply take a look at the Label.Font property. That wasn't hard, was it?

Hi all,
In my project i am reading a binary file of 81MB size and this information need to be inserted in to different tables of database.
The binary file is having several sections, contains some millions of records. while reading the binray information i am conveting the bytes in to c# datatypes and saving in arraylist, finally i am inserting in to the database Which is taking huge amount of time.
to insert this 81 MB size file in to database my application is taking 30 min.
Can any one suggest me how can i optimize the performance?
Thanks in advance

Hard to say.
There are a lot of ways to boost performance.
- Is the algorithm optimized? Are your for loops ok? (you don't perform actions in for loops that could be done outside eg.)
- Do you have GUI updates like a progress bar or something?
- Try an Ngen compilation, it might help (See MSDN)
- Can you use threads? eg Read in a block of bytes and while the DB updates, Read the next block at the same time etc...
- Did you use optimezed objects? (StringBuilder for string concatination eg.)
Hope this helps...

Hi,
You are use following tips/suggestions/whatever 
1. Dont use INSERT when "LOADING" the data, use BULK INSERT
2. You can convert the data into c# format, and dump it as required in some temporary file, and bulk insert data using that file. If you are good at threading, you can boost the performance considerably.
3. If you are comfortable with Dynamic SQL, use it after converting data to c# datatypes.
And if you are good in threading and dynamic SQL then you can have a boost in performance as "complete loading of a 45 GigaBytes of data to 12 tables in 1.5 hours". That is what i experienced once!
Hope that much performance is enough for now and you find it useful!

I'm Having a combobox which having items from itemtable. When table is empty then I have to show "No items" and if items are their in table then I have to show the item. So I fill datatable like
if (dataTableItems.Rows.Count >= 1)
{
cmbItem.Items.Clear();
cmbItem.DataSource = dataTableItems;
cmbItem.DisplayMember = dataTableItems.Columns["ItemName"].ColumnName;
}
else
{
cmbItem.Items.Clear();
cmbItem.Items.Add("No items");
cmbItem.Text = "No items";
}
This is working fine on form's load event.
But I have a button that will get items from other datatsource and fill the item tables. On click of the button I again fill the datatable and same code
if (dataTableItems.Rows.Count >= 1)
{
cmbItem.Items.Clear();
cmbItem.DataSource = dataTableItems;
cmbItem.DisplayMember = dataTableItems.Columns["ItemName"].ColumnName;
}
else
{
cmbItem.Items.Clear(); <-- ERROR COME HERE
cmbItem.Items.Add("No items");
cmbItem.Text = "No items";
}
But it will give error "Items collection cannot be modified when the DataSource property is set."
please help
