Hello
I am trying to use principal permission in my code, using the imperative security permission, as follow.
appAdmin.CurrentDomain.SetPrincipalPermissionPolicy(PrincipalPolicy.WindowsPrincipal);
void doMe()
{
PrincipalPermission iPerm = new PrincipalPermission(null,"RoleName");
iPerm.Demand();
}
And then I created a new role ("RoleName") and assign it to my user, using the azman console.
But when I am trying to run this code, I get the exception: "request for principal permission failed".

I have a string, oldWord, that contains exactly 1 space SOMEWHERE in it. I want to generate 26 copies of that word with the space being converted to a letter, 'a' through 'z'.
I tried this:
string oldWord;
string[] newWord;
...
for (int c = 0; c < 26; c++)
{
newWord[c] = oldWord.Replace(' ', 'a'+c );
}
The compiler complains about the parameter, 'a'+c , as being an "invalid char", as you probably expected. I've tried lots of different combinations, to no avail. Would you please tell me how i can code that parameter so i get the expected result?
Thank you.

Hi!
Do it like this:
newWord[c] = oldWord.Replace(' ', (Char)((int)'a'+c));
It converts the 'a' to a value, add the additional value and convert it back to a character.

Hi,
You can also try this ...
<br />
string oldWord = "Hello Welcome";<br />
string newWord = "";<br />
for (int c = 0; c < 26; c++)<br />
{<br />
int newchar = (int)'a'+c;<br />
newWord += oldWord.Replace(' ', (char)newchar );<br />
}<br />
System.Diagnostics.Debug.WriteLine(newWord);<br />
Result:
<br />
"HelloaWelcomeHellobWelcomeHellocWelcomeHellodWelcomeHelloeWelcomeHellofWelcomeHellogWelcomeHellohWelcomeHelloiWelcomeHellojWelcomeHellokWelcomeHellolWelcomeHellomWelcomeHellonWelcomeHellooWelcomeHellopWelcomeHelloqWelcomeHellorWelcomeHellosWelcomeHellotWelcomeHellouWelcomeHellovWelcomeHellowWelcomeHelloxWelcomeHelloyWelcomeHellozWelcome"<br />
Happy Programming!!!

Here is another suggestion: Why not use a character counter:
int i = 0;
for (char c = 'a'; c <= 'z'; c++) newWord[i++] = oldWord.Replace(' ', c);
---
b { font-weight: normal; }

Thank you ALL for the excellent suggestions. I tried the 1st 2 suggestions before the 3rd was made ... they both worked great ... PLUS i got the added benefit of learning how to 'cast'.
Thanks again,

DateTime.Now.AddDays(-1);
|
|
|
|
|
Hi!
Just use the methode AddDays from the DateTime-class and give as parameter a negative value.
DateTime loDate = new DateTime();
loDate = DateTime.Now;
loDate = loDate.AddDays(-1);
MessageBox.Show(loDate.ToString());
other samples:
loDate = loDate.AddDays(-5); // Subtract 5 days
loDate = loDate.AddMonths(-3); // Subtract 3 months

Try using
DateTime dt = DateTime.Now ;
dt = dt.Subtract(new TimeSpan(1,0,0,0,0)) ;
Console.WriteLine(dt.ToShortDateString()) ;
Hope this helps.

What is the difference between Singleton implemented using static GetInstance() method and having a Class with all Public Static methods. Is scenario#2 a Singleton class? Please let me know the differences between these two approaches.
1)-----------------
public class SealedClass
{
private static SealedClass _class = new SealedClass();
private SealedClass()
{}
public static SealedClass GetInstance
{
get
{
return _class;
}
}
}
--------------------------------------
2) public class StaticClass
{
public static string GetName()
{
return "Shubho";
}
public static string GetAddress()
{
return "Shubho";
}
}

Interesting question.
According to the GoF, the purpose of a singleton is to "ensure a class has only one instance, and provide a global point of access to it." Your second example has no instance, its just a collection of static methods and hence we couldn't get a reference to it.
Microsoft has a best practice with regard to singletons - they say it should be implemented as follows - a thread safe lazy implementation
public class Singleton
{
private Singleton() {}
private static volatile Singleton _singleton;
private static object _lock = new object();
public static Singleton Value
{
get
{
if (_singleton == null)
{
lock(_lock);
{
if (_singleton == null) _singleton = new Singleton();
}
}
return _singleton;
}
}
}

Sos... I'm creating a graphical shapes that represents "cut off" pieces of a roll of material.
Problem: I need a algorithm that applies optimal control on these shapes to graphically show how a roll of material can be cut to utilise it's full potential and also show the wastage factor.
Can anyone help. pa-lease

Your best bet with this is to google the terms which relate to this procedure, I would, but im struggling to name it - you may know better as you are dealing with it.
Once you find something that looks relevant, post links to the information you find, and im sure someone here can help you turn that into some code.
Although, you may be lucky, someone out there *might* just know this off the top of their head, the internet is a big place.

Am having a Treeview with many nodes each of which have their own subnodes...
I want to move and copy the selected node(if one node selected,hence its subnodes too) to another treeview...
How can i do it...
Can anyone help me in codes...
Thanx....

Mahi.V.Ragava,
Let's assume that you have two TreeViews (treeView1 and treeView2) and a button (button1) to move TreeNodes from treeView1 to treeView2. Then, you can have the following event handler.
private void button1_Click(object sender, System.EventArgs e)
{
if( treeView1.SelectedNode != null && treeView2.SelectedNode != null )
{
TreeNode n = treeView1.SelectedNode;
treeView1.SelectedNode.Remove();
treeView2.SelectedNode.Nodes.Add( n );
}
}When you get the reference to the selected node in the first tree, its Nodes collection already contains all subnodes. Therefore, when you add that TreeNode to the second tree, all the subnodes already exist and get put in automagically.
