It should be noted that the arraylist uses arrays internally and it does the same as described above.
So creating new arrays and copy its content is not slower than using the arraylist.

but do use the lists since they are already created for this purpose, but dont expect them to be any faster..

2.0 does have a Resize method

int[] arr = {1,2,3,4,5,6,7,8,9};
Array.Resize(ref arr, 3);
or
Array.Resize(ref arr, 20);

only two letters away from being an asset

There is the static System.Array.Resize method, however, as others have stated, if you need to be resizing lists, your best bet is to use the System.Collections.Generic.List object.

Yes, you can resize arrays while preserving existing contents in C#:

However, as others have mentioned you may want to use an ArrayList(2003) or a generic List (2005) instead.

TextBox filling in Crystal Reports VS2005

Hello

if you're dealing with a datatable in a dataset, why not trying something like this

int Max = 0;
foreach(DataRow MyRow in MyDataTable.Rows)
{
    if((int)MyRow.ItemArray[MyIndex].Value > Max)
        Max = (int)MyRow.ItemArray[MyIndex].Value;
}

I hope I got you right

Hi,

Slightly off topic - if you know of a good place elsewhere to ask then please let me know Smile | :)

I want to put a textbox or field into a crystal report and that textbox is filled by reading in a text file at run time. To clarify, a user types in their text which could be several pages using their favourite wordprocessor and then the contents are incorporated into the Crystal Report generated by the program in much the same way as database fields are.

Is this possible?

If not, are there any alternatives to achieving the same end result?

In older versions of Crystal the answer was no although you could have tried working with OLE objetcs (not recommended, it was a nightmare!) but now with the latest versions you can write VB code that should permit you to do what you want. I think you need at least version 10, or maybe version 9 can't rmenber exactely when VB code was introduced.

I was looking at this and I think you're right Hmmm | :|

That's the version that ships with VS2005 - or at least a cut down version anyway.

Any idea where I may be able to find somewhere on the net that tells me how to do it?

Personnaly I lloked at the version that ships with VS and ordered the full version right away. There is no way you will create reports with this version if you want to use the features of Crystal Reports. In the shipped version you have to prepare your data before hand and then create the report besed on that.
If you feel you need more help try the http://www.businessobjects.com but again, any help you get from there might not apply as you don't have the full version.

I am reading pixel by pixel from a image, creating a color object corresponding to that pixels color and witing a "." into a word file and coloring it with the same color as the pixel.

But Word.wdColor has only 60 colors I am not able to relate the color object with Word.wdColor enum.

Hi,
The only way I could capture the TAB key was on the KeyUp event

Do your best to be the best

Kais4U28-Aug-06 1:38

The keyup event does not get fired if you select the button and hit tab. The only event gets fired is the leave event.

Nader Elshehabi28-Aug-06 1:52

Hello

The best thing to do, I believe, would be to handle the LostFocus event. It will be fired when the button loses focus whether by the tab key or the mouse.

Isn't this what you want? If not, please give more details.

Regards

Hi,

Thank you for your quick response.
As you mention, the lost focus (Leave event for the button) will get fired for both key board and mouse movements.

I explicitly need to capture Tab event generated on the button so that I can set the focus to some other control on the form. The reason is, Am using MDI form and displays two child windows side by side. On the first child window, when the focus is on the last control and the user clicks on TAB, the focus should go to the first control of second child window.

Hope things are clear and you might be in able to help me out.

Thanks

Regards
Kais

Hello

If you are using .Net 2.0 framework, handle the PreviewKeyDown event

private void MyButton_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
        {
            if (e.KeyData == Keys.Tab)
                MessageBox.Show("Tab");//Your code goes here!!
        }

I hope this helps Smile | :)

Hello,

Do you whant to navigate with the Tab Key?

Kais4U28-Aug-06 2:06

28-Aug-06 2:06

Yes, I need to navigation on the screen thru TAB.

Actually, Its MDI form and has two child windows displays side by side. On the first child window, when the focus is on the last control and the user hits TAB, the focus should go to the first control of the second child form.

Thanks in advace for all your suggestion/help
