Following points may help
(1) Please Subclass the TextBox displayed.
(2) Override the PreProcessMessage and Fire a custom event on the -> (right arrow event).
(3) Subscribe to this event in the ListView. In this method just change the focus to the next TextBox.

I create a datatable with 3 columns at run time and set it to a Datagrid. Datagrid has 5 extended columns. for example one is numeric column, other is a date time picker, other is button.
I aim to create as a form like EXCEL but with special columns.

I add a row to datatable after creating. I want to add others when the user fills all fields or press down key.

I couldnt achive yet, there is always problem, Could u advise another method to do that?

o buy a third party datagrid library that isn't as brain dead as the built-in version.

o look at some of the nicer controls on this site (http://www.codeproject.com/cs/miscctrl/csharpgridcontrol.asp[^])

o waste many hours of your life researching the functionality of the builtin datagrid, determine that it sucks, and end up doing one of the above two things anyway.

The Graphics object gives you all the methods you need to draw onto a Bitmap. Check MSDN for more info. You should draw it to the screen in your OnPaint handler, and call Invalidate for force a redraw when it changes.

Constant declares

I need some help understanding basic c# layout regarding constant declarations. I have some global constants I'd like to declare for my windows.form based app such as:

const int APPLICATION_STATE_PAUSED = 0;
const int APPLICATION_STATE_RUNNING = 1;
etc...

Where is the correct place to declare these so they will be accessable by all forms and classes in my project?

Thanks - mutty

The only way to make them globally visible is to create a class that has them as public static members. There is no global scope in C#. Personally, I think this looks like C code, I'd ditch the all caps syntax, and maybe even use an enum instead.

const is only good for compile time values, for run time values, they need to have class scope, and be declared in the constructor, and they need to be readonly, not const.

Where would I put the enum to make it globally visible?

Christian Graus10-Aug-05 16:59

10-Aug-05 16:59

Same again, there is no such thing as globally visible, excepting public and static on a class that you use to hold this sort of stuff. Or just outside any class, if they all have the same namespace.

Anywhere you want outside a class declaration.

Create a struct that has static accessors to the constants you want to define. Such as:

public struct Aprori
{
static public int Running
{
get { return _Running; }
}
private const int _Running = 5;
}

...

Then access it by

int x = Aprori.Running;

That way you have one object that contains your constants and is easily accessed. If you have differing constants you can group them in other structs for similar purpose.

I'm trying to write a small program (just for experience) that I can use to change my desktop wallpaper, but I can't see to get it right. I'm using the following code:

Bitmap img = new Bitmap (path);
try
{
    img.Save (path, System.Drawing.Imaging.ImageFormat.Bmp);
    SystemParametersInfo (0X14, 0, path, 0X1 | 0X2);
}
catch (Exception ex)
{
    MessageBox.Show ("There was an error setting the wallpaper: " + ex.Message);
}

path is the path to the image file which is currently in jpg format. When the img.Save line executes it throws an exception that says simply, and quite unhelpfully, "A generic error occured in GDI+". Any help on what I'm doing wrong would be appreciated.

Thanks.
