Hi Guys
How to set a description for a property in a class? I have found some articiles talking about method description using summary tag. summary.../summary. But it doesn't seem to be working for properties.
Can any one help me on this?
Thanks in advance.
Muthu.

You do use the summary tag. This is an example:
public int Id
{
get { return _id ; }
set { _id = value; }
}
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

I'm sorry. I didn't mention that it is for intellisense description.
I tried both ///summary and System.ComponentModel
I didn't get intellisense description in both cases.
Thanks
Muthu.

The properties shown by Visual Designer are not from the /// tags, but from
the Description attribute, which is unfortunate, since this makes me write
the same thing twice, as in:
using System.ComponentModel; // Category, Description
/// <summary>
/// Gets or sets the initial color of the overlay.
/// Use Color.Transparent to make it always transparent, or
/// some opaque color to get the scratch functionality.
/// </summary>
[Category("ScratchPanel"), Description("Gets of sets the initial color of the overlay. "+
"Use Color.Transparent to make it always transparent, or "+
"some opaque color to get the scratch functionality.")]
public override Color ForeColor {
...
}

Yes you are right, there is an issue. I havent noticed this before:
Visual Studio 7.1 does not show Intellisense for properties (it does for methods e.a.),
but Visual Studio 8.0 does !

public void abcMethod1()
{
string cspurl = @"http://xyz.aspx";
bool expected = true;
bool actual;
actual = @"http://xyz.aspx";
Assert.AreEqual(expected, actual, "");
}
Here actual Value means, what could i assign for actual variable as am getting mismatch error, as i assigned string value to bool variable.

Why are you testing a string value to a bool?
Don't you mean:
Assert.IsTrue(cspurl==actual, "Check string equality");
|
|
|
|
|
even then am getting an error, "Operator '==' cannot be applied to operands of type 'bool' and 'string'", if i use the
Assert.IsTrue(cspurl==actual,"Check string equality");
|
|
|
|
|
you declared actual as a bool. Declare it as a string.
|
|
|
|
|
public void abcMethod1()
{
string expected = @"http://xyz.aspx";
string actual = ...;
Assert.AreSame(expected, actual);
}
|

I probably don't understand this, but from when we can assign string values to bool (which is always true or false) data value type ?!
If you need compare two strings (use string's .Equals function) :
string ww1 = @"http://xyz.aspx";
string ww2 = @"http://xyz.aspx";
if (ww1.Equals(ww2))
{
// oh yes
}

I have 2 List<string> objects A and B.
I would like to compare A against B and get the following information:
Which elements are only contained in A?
Which elements are only contained in B?
Is there a standard algorithm for this?
Thanks,
Kathy.

One way is to first sort the lists, then you can easily loop through them side by side and compare them.
Pseudo code:
sort A
sort B
loop {
get a from A
get b from B
if a < b
"Only in A: " + a
advance A
else if b < a
"Only in B: " + b
advance B
else
advance A
advance B
}
You have to keep track of when the lists end, also. I did not include that in the pseudo code, for simplicity.

Thanks.
I should also mention that the lists could be different lengths.

I took for granted that they could be, as you want the items that are present in only one of the lists.

here's my final:
private void diff2()
{
List<string> aList = new List<string>();
aList.Add("a");
aList.Add("d");
List<string> bList = new List<string>();
bList.Add("z");
bList.Add("a");
CompareLists(aList, bList,
delegate(string a) { Console.WriteLine(a + " only in list a"); },
delegate(string b) { Console.WriteLine(b + " only in list b"); },
delegate(string c) { Console.WriteLine(c + " in both"); }
);
}
delegate void InList(string inputValue);
private void CompareLists(List<string> al, List<string> bl, InList onlyA, InList onlyB, InList both)
{
int a = 0;
int b = 0;
al.Sort();
bl.Sort();
while ((a < al.Count) && (b < bl.Count))
{
int cp = al[a].CompareTo(bl[b]);
if (cp < 0)
onlyA(al[a++]);
else if (cp > 0)
onlyB(bl[b++]);
else
{
++a;
both(bl[b++]);
}
}
while (a < al.Count)
onlyA(al[a++]);
while (b < bl.Count)
onlyB(bl[b++]);
}

Below a quite different approach in pseudocode:
Collection common=new Collection();
foreach(object i in a.Clone()) {
if (b.Contains(i)) {
a.Remove(i);
b.Remove(i);
common.Add(i);
}
}
At the end, you have three collections: common holds the common items,
a and b only keep the non-common items.
a.Clone is necessary since we want to modify a while enumerating.

I was trying to schedule the computer to go into standby / hibernate mode. After a specified duration I wanted the PC to come out of standby. I wanted to automatically send my computer to standby between specific times of the day.
Its easy enough to send the computer into standby, how do you bring it out?
Does anyone know how to accomplish this?
Thanks in advance.

I would like to know how can i move with IEnumerator movenext and moveback, that is forward and back in the list iterated.
|
|
|
|
|
IEnumerator only supports moving in a logically forward direction. Further, the Reset() method is optional and may not be supported by all instances of IEnumerator.
