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 ,
Jacco

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.

How to play a sound from my program.
I have Visual Studio 2003.
Net 1.0.]
Help.

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 
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);

Could someone point out why there is an error here?
Thanks.
class BankAccount<br />
{<br />
<br />
decimal m_ID;<br />
<br />
public BankAccount(string ID)<br />
{<br />
m_ID = 0;<br />
}<br />
<br />
}<br />
class SavingsAccount : BankAccount<br />
{<br />
decimal m_ID;<br />
<br />
public SavingsAccount(string ID)<br />
{<br />
m_ID = 0;<br />
}<br />
}
|
|
|
|
|
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) { ... }

How can I display drgged object's shadow (or faded image) with the mouse pointer? Thanks.
|
|
|
|
|
You can change the cursor if you have a static image you want to show under the mouse. Otherwise, you need to draw it yourself.

If i make a stream of some sort out of it, and write to the stream, will the online file be edited?
I don't suspect so. Is there something i can do to do this?
|
|
|
|
|
Sure - if you have FTP write access, you can read the file, change it, and write it back.

Excellent, im so happy... well y'know.
|
|
|
|
|
when i'm looking at a value and using console.writeline(byte[0]); to print the output of a network stream. i am getting a 69 printed to the screen. is this an octal number or the binary number 69? 01000101?
|
|
|
|
|
It is 69 in decimal (01000101 binary). I don't know how/if C# can display octal.
A byte array is just a bunch of bytes - numbers that can range between 0-255 decimal, 00000000 to 11111111 binary, or 000-377 octal.
HTH,
Mike

If it was octal, it wouldn't have a 9 in it. If it was binary, then it wouldn't have a 6 OR a 9 in it.
I would have thought byte was a keyword and couldn't be an array name...
If you're worried, use ToString and pass it a format so you know what it is.

Hi All,
I have a product which I am planning on distributing to a few Beta testers. I thought it would be a good idea to incorporate some sort of licensing/registration scheme for it, so I can control it, have a trial version that expires after a certain period of time, etc. Does anyone have any experience with licensing solutions that can be used with .NET components?
Thanks,
Aaron

I'm trying to get a delegate to a property. Tip 2, solution 2 of the article linked below gives a way to do it. It works but a typo in the propertyName wouldn't be detected until runtime.
http://www.codeproject.com/csharp/csharptips.asp
<br />
private MySetDelegate xSetter = (MySetDelegate)Delegate.CreateDelegate(<br />
typeof(MySetDelegate), targetObject, "set_X");
I'm looking to replace the "set_X" parameter with the equivilant of "set_" + GetPropertyName(targetObject.X), but having never used reflection before I don't know how to implement GetPropertyName or the equivilant.
|
|
|
|
|
Maybe I misunderstood the question, but you already have the property name (targetObject.X). Why do you need it again?
BTW, you can also achieve the same effect by creating a delegate to PropertyInfo.SetValue[^]. The code would then look like
class Test
{
int x;
public int X
{
get {return x;}
set {x = value; }
}
}
delegate void XDelegate(object obj, object value, object[]index);
static void Main(string[] args)
{
Test t = new Test();
PropertyInfo propertyInfo = t.GetType().GetProperty("X");
XDelegate xdel = new XDelegate(propertyInfo.SetValue);
xdel(t, 2, null);
Console.WriteLine(t.X);
}
