I just finished Tom Archer's Inside C#[^] and I thought it was a great read. It covered basic OO design concepts, and how they apply to the C# language. Great for beginners, and has enough substance for an intermediate-type guy like myself.
Definitely worth a look...

Hello there,
does anybody know how to find out the height
of a specific row in the DataGrid control?
I cant'use the PreferedRowHeight property
because the user could have changed the height
of some rows and I have to consider that.
Thanx a lot.

DataGridTextBoxColumn has a TextBox property. May be TextBox.Height will be usable.

Hi,
I have a collection of many objects (Collectionname : contracts; object : Contract).
I have also a listview I fill up like follows :
foreach(Contract contract in Contracts)
{
listview1.Items.Add(contract.number);
listview1.Items[listview1.Items.Count - 1].SubItems.Add(contract.name);
....
}
listview1.Focus();
In my collection I have a 7000 objects and in the listview I show only 15 lines.
Is there a way that I only fill 15 lines in the listview and when I scroll down or up I fill the following lines.
I think that it takes a lot of performance when filling up the whole listview.
Is there somebody who have idea's or knows some good articles?
Thanks,
x

you might notice a big speed increase in populating the list if you put listview1.BeginUpdate() before you start the loop, and a listview1.EndUpdate() after the loop..
still a newb.. cut me some slack :P

Hi folks,
I have a requirement to read data from a flat file and dump it into the database which is an oracle database. I know the best way to go doing about this is to use Microsoft DTS.
But what a pitty, my project uses only oracle and .NET. I wanted to know whether there is a bulk load utility available to load data from flat,csv and excel file to database.
i am not lookin at sql loader since this process should happen from App server and not from database server.
Anyone has any inputs or suggestions..

Thanks kannan
I had a look at it, and my initial impression is it will be a over kill
for such a small functionality like which i have. Probably for a enterprise system it should be ok.
My only job is to read line by line and insert into a table.
i am looking at some BCP apis
thanks again

I try to use "\n" in C# - textBox1.Text=textBox1.Text+"\n", but it don't work.
Maybe some endl or endofline ?
How I can solve this problem ?

And make sure your textbox is multiline too!!
|
|
|
|
|
Or you could use Environment.NewLine

 :-DThat works perfectly. Thanks.

I used Microsoft's way of adding a combobox to a datagrid by just adding a combobox to the datagrid's controls and moving it to the proper row and column when CurrentCellChanged is fired.
http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q323167
This code they give is in VB.Net, and I assume it works because many people have used it (from reading on forums). However, when I converted it to C# it does not drop down when it is clicked. I do add it to the DataGrid.Controls and it is displayed. I do not think i should have to add events for clicking, the combo box is in the datagrid's controls and should receive the click event itself and drop down. If it works in VB.Net I can't see why it would be any different in C#.
Has anyone ever done their example in C# and got it to work, I know I can make my own DataGridColumnStyle and i have found examples of it that work. But I really like the simplicity of Microsoft's way and the fact that I should be able to just add any control to the datagrid.
Thanks for any help.
