Re: how to write check value in textbox

This is not very legible, but I think you want to validate input ? You can handle the KeyPressed event and set e.Handled to true if you want to reject the keypress, or use a MaskedTextBox

I was not sure if you were asking this of a Web Form or a Win Form. I would use a custom validator control if it is a Web Form, but the below will work for both.

private void btnCheck_Click(object sender, EventArgs e)
{
bool Numeric = IsNumeric(txtNonNumeric);
}

private bool IsNumeric(string strText)
{
try
{
Convert.ToDouble(strText);
return true;
}
catch
{
return false;
}
}

Increase the size of a label

Hello,

I have a Windows ListView, whose view is set to "List" and then it shows an icon in front of each item and some text in front of it.

The problem is that its showing only first few characters of the text.

Does anybody know to increase the size of this label/text for each item, so that it can atleast show 12 characters.

Thanks

The ListView has an Items collection, you can use this to set the width of an item, I believe.

Thanks for replying.

There is no such or similar property.

Yes, there is.

MSDN Library: ListView.Items[^]

b { font-weight: normal; }

Yes, there is, but it's not what you want

listView1.Columns[0].Width = 20;

Is how you set column width.

Yes there is offcourse Items property but I meant that there is no property on it by which its size, etc can be changed.

Increasing the column widths will do.

Thanks for the quick responses.

Cheers

Hi,

Is there any other way of increasing the label size other than increasing the column widths?

Thanks

I have build a server application with Sockets. My question is simple.
Is it possible to see how many and what clients are connected? If yes then how?

Kind Regards ,

I always keep track of the connected client sockets, so that I can disconnect them at will, for example to restart the server in a correct manner. If you keep track of the connected client sockets, you can simple get the size of the list which gives you the number of connected clients.

using System.Runtime.InteropServices;

[System.Runtime.InteropServices.DllImport("kernel32")]
private static extern int Beep(int dqFreq, int dqDuration);

Beep (3000,25);

=> It will play a nice beep like in '80 years Poke tongue | ;-P

If you are not happy with that you can also use the MCI functionalities provoded by the API (need import also)

or ... simply play wave with:

[System.Runtime.InteropServices.DllImport("Winmm.dll")]
private static extern bool PlaySound(byte[] data, IntPtr hMod, UInt32 dwFlags);

Since the SavingsAccount ctor doesn't have an explicit call to the base class ctor, the compiler will insert a call to the default ctor (the one with no parameters). But there is no such ctor, so you get the error. You need to add the call to the initializer list:

public SavingsAccount(string ID) : base(ID) { ... }
