The PUT method is disabled by default in the web server. You have to enable it for the server to accept it.

Hi,
I need to pass values dynamically for a return type of a particular property.How could i do this.
Actually what happend is:I need to display time according to the user selected format.For that I have taken a proprty and that has constants.So for that i cant send values.I need to send the values only for the retun type.How could i do this.

I have no idea what you are talking about. Perhaps if you illustrated it with an example of what you are doing and what you want the result to be.

If i understand you correctly you need to return date in the format specified by the user. Does the user input the format (e.g. MM/DD/YY)? You could return as String and cast to the proper format.

You can override ToString and use it or you can just do like: yourTimeHoldingClassInstance.Time.ToString(userSuppliedFormatString);
public class YourTimeHoldingClass
{
public DateTime Time
{
get { return this.time; }
set { this.time = value; }
}
private DateTime time;
public override string ToString(string format)
{
return time.ToString(format);
}
}

Hi,
I am new to .NET, someone plz help me with the simple code below.
public partial class FontSelection : Form
{
public FontSelection()
{
FontFamily [] ff = FontFamily.Families;
for (int i = 0; i < ff.Length; i++)
{
try{ lbFonts.Items.Add(ff[i].Name);}
catch(Exception e )
{ MessageBox.Show(e + " null exception") ; }
}
}
}
I am getting NullReferenceException when I run it. I understood from reading some message boards that NullRefereceException is occurring here coz i havent instantiated the fontFamily. How do i do that?
I saw on help the overload list of FontFamily class and used FontFamily (String)
I tried ff[i] = new FontFamily ("Font") but complier doesnt like it. Im not sure what else to do, so plz help me

Hi,
May I suggest you:
- use a debugger to single-step your code.
- or you insert Console.WriteLine statements to see progress and intermediate results
(such as ff.Length)
- make sure lbFonts is not null.

I doubt that the FontFamily array is the problem as you get it from the static Families property and I doubt that the elements of this array aren't initialized. Otherwise you would have found a bug in .NET Framework and should report it. But I think it is more likely you forgot to initialize lbFonts which then causes the exception.

Ok, but lbFonts is a listbox which i dragged and dropped on the form in visual studio. Do i need to initialize it? I assumed it is done automatically when u drag and drop the component on the form.

It should be done automatically, but maybe something gone wrong or you're calling the method at some moment of the form's lifetime were it's already uninitialized. As the other poster said use the debugger to find the cause of your exception.

hi.
on my system this code runs fine. both as a class and as a method. however i didn't extend class from Form, rather just created a form and added a control. check your initialization code for FontSelection class (in addition to the base class Form).
regards.

Create a shortcut to the exe inside the "Startmenu"-"Programs"-"Autostart" folder.

Add a new string value to the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run that points to your app.

Or, more properly, create it as a Windows Service so that the end user can control the start up mode for the application, e.g. does it start up as Automatically or Manually.

hello
i'm trying to use the values i get from this code
for(int i=0;i<count;i++)<br />
{<br />
indice[i] = TableListBox.CheckedIndices[i];<br />
MessageBox.Show(indice[i].ToString());<br />
}
where TableListBox is actually a CheckedListBox and its checked indices are being stored in another array.
Now the problem is that when i run this code from its respective form it works fine, but as soon as i close the form and try to access this chunk of code from another form, it gives me the Index out of bound exception for CheckedIndices. i expect this is due to the reason that as soon as i close the form with the CheckedListBox, all its values are discarded.
i've tried solving this problem by storing the CheckedIndices into a static array, but it still is giving me the same exception.
So plz can anyone guide me about this problem of mine and tell me how to retain the checked indices after the form has been closed.
Thanks and awaiting ur reply

First the info you've provided isn't suffecient to judge the problem, but I'll take few guesses here.
1- The way you use to copy the array -ignoring the MessageBox of course- is quite wrong. You should use Array.Copy() or Array.CopyTo() static methods instead.
2- Failure of the static array ecludes that discarding the values of the CheckedIndices when closing the form is the problem.
3- Make a breakpoint and see the values of:
a. count
b. CheckedIndices.Count
c. indice.Count
Waiting for your reply.

well nader
the way i'm copying indices like this is due to the requirement of my problem.
the code i mentioned above is actually a function of form A. when i access this function from Form A, it works fine. But as soon i call the function from Form B it gives the exception. the complete function is:
public int[] GetCheckedIndices()<br />
{<br />
int count=Global.Instance.Count_Indices;<br />
indice = new int[count]; <br />
MessageBox.Show(count.ToString());<br />
for(int i=0;i<count;i++)<br />
{<br />
indice[i] = TableListBox.CheckedIndices[i];<br />
MessageBox.Show(indice[i].ToString());<br />
}<br />
return indice;<br />
}
now TableListBoxis the name of me checkedListBox
and CheckedIndices is its property.
indice has been declared as "public static int[] indice".
CheckedIndices.Count has the index of the items that have been checked in the chckedListBox.
ope this gives u enough information to understand the problem
awaiting you reply.
