You can really make an array of Forms. Then cast to the proper type when required. For instance:
Form1 frm1 = new Form1();
Form2 frm2 = new Form2();
...
Form [] frmArray = new Form[n];
...
Form[i].Show();
frmArray[i].Show();
...
((Form1) Form[i]).MyCustomTextBox.Text="foo";
((Form1) frmArray[i]).MyCustomTextBox.Text="foo";
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

How can I get the list of valid domain users of the XP/2000 domain to which I belong ?
My aim is to develop a C# / VB.Net desktop application which can be accessed by valid users of my domain. I cannot have a user management section for my application. It has to detect all valid user of my domain and work among them. Nor users need not log into this application and still get data pertaining to them alone. Administrators can see list of users of domain and send messages etc. I hope, I made it clear.
Thank you

Hi all
I'm newbe to platform invoke in C#.
I need to retrieve the text of an item in a Listbox.
I should send a SendMessage sending a LB_GETTEXT message
with lParam as as a Pointer to the buffer that will
receive the string.
I always used this declaration for SendMessage that worked until now.
[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr SendMessage( IntPtr hWnd,
uint Msg,
uint wParam,
int lParam );
My problem is that I need to past to lParam a pointer to a string
or a buffer.
I tried using casting or directly StringBuilder object but
without success.
Do you know why this happens and how to use
this SendMessage to retrive the string I need?
Regards
ManuStone

If you need to use it with StringBuilder, declare it like so:
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
static extern IntPtr SendMessage(HandleRef hWnd, uint Msg, IntPtr wParam, StringBuilder lParam);
See P/Invoke.NET[^] for more info.

Can anyone tell me how to use a wait cursor, while some file execution is going on?
Consider the case. I have to load some file to a datagrid, which takes say approximately 8 seconds.
during that period, I want to show a wait cursor, so that the user has an idea that something is going on. Please tell me an easy way to do this.
Thanks in advance

Take a look at the Cursor class.

I'm using a dictionary object to store data but it seems that it can't be ordered by the key name. I assumed that a dictionary would be ordered by key somewhat like one of those book things that you look words up in, you know those hmmm, what's the word, oh, dictionary things.
Do i need to write my own collection to support this behaviour?

I'd been searching for dicionary sort; sortable dictionary and hadn't found anything
SortedDictionary looks just the thing

i have found this:->
dset.Tables["tab1"].Merge(table);
|
|
|
|
|
use this
DataSet dataset = new DataSet();
dataset.Tables.Add("aaa");
adapter.Fill(dataset, "AAA"); // Fills table "aaa" because only one similarly named table is in the DataSet.

Hi,
I am not able to set focus on a tird party grid when I tab out of a text box control placed before the third party grid.
Please help

Are you sure your tab order is correct. It could be if the tab order was changed your third party grid would get focus.
Hope that helps.

Hi,
I'm not a web expert (I suppose you're talking about web development), but how do you thing can focus a data grid ? It is not a control, it's just a table with bunch of labels, texboxes and links in it.

i am talking about a grid in my windows application....It has 3 - 4 cells in each row..I want the focus to be in the first cell of the first row
