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?

SortedDictionary looks just the thing
Thanks again

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

Well, ok.
It's a third party datagrid. Do you have sourcecode that u can change to make it work your way? If yes, how do you know that the control doesn't have focus. It may have focus but if it is customly drawn it's proboble that it just doesn't change (visual side) when recieved focus. If you have sourcecode just override void OnGotFocus(EventArgs e) method and make it focus the first cell in the first row. That will cause, of course, allways when you click on that control focusing that cell. There is way to change it (i.e. if you dont want to put the focus on first cell when mouseclicked, only when tabbed). Anyway , do you have source code? If not i guess, there is not much u can do about it...

As u say 'It may have focus but if it is customly drawn it's proboble that it just doesn't change (visual side) when recieved focus.'
here I am losing the focus that means I am not able to get the fous on any control after the third party grid when I tab out
Regards,
Sivaprasad

first u told that u are not able to focus the grid, resp. first cell on the grid. now u telling that u are not able to pass focus further from the grid ? U cannot loose focus. It just somewhere (probobly on the grid and it is not displayed). But u haven't answered my question. Do you have source code?
|
|
|
|
|
I told that I am not able to focus on the grid, WHICH IS MY PROBLEM.
But u told that focus will be ther but we cant viwe it ...thatz y I told that if focus is there and we cant view it the focus should atleast pass to the next control after the grid when I tab out rite??
I hope u understood my probl;em
No I dont have the source code.

Sivaprasad

Now I understand  . Generally speaking if your grid is derived from System.Windows.Forms.Control, it can recieve focus. If that control has focus and tab is pressed, any child controls inside will be focused. After last child control is focused, focus is passed to another control (on same level as your datagrid). If your Datagrid is derived from System.Windows.Forms.UserControl, it won't recieve focus, only it's children. This is default behaviout which can be changed and it's really hard to help you if u cannot change the source code.
There is one thing u can do. U can hook on GotFocus event of your datagrid. Whenn triggered, try to browse child controls of that grid and focus first one(or maybe first one of type TextBox) . But that may not work at all, depends on implementation of that datagrid...
hope that helps...
