It looks like a homework assignment to me. Not a question at all. Smile | :)

You should attempt your homework questions yourself. If you get stuck post the code and we'll help you out. However, we ain't gonna do it for you.

You have conquered this level.

You now move to the next level:
Enter a 10-digit integer number consisting of odd digits only, and write a program
to print the next 5 primes.

Shame on you.... Go do you own homework, if you have a specific problem with your homework, such as why something isn't working as you expect, then ask a question. But don't expect people to do your work for you. It won't get you far in the industry.

override issue

Hi,

I am creating a custom membership provider, one of the properties I had to override as follows:

public override bool EnablePasswordReset
{
get { return m_EnablePasswordReset; }
}

In my Initialize method I have to go and set m_EnablePasswordReset. I don't like setting private variables without using a property. Why can't I add a setter in this property like:

public override bool EnablePasswordReset
{
get { return m_EnablePasswordReset; }
set { m_EnablePasswordReset = value; }
}

I hope someone can help.

Regards
ma se

String parameter is not equal

11-Jul-07 4:57

you can if there is a virtual property with both a get and a set part in the base class.

that's what the error message should indicate (I guess it is: "no suitable method found
to override")

Of course it depends on base class property declaration.
BTW

public virtual bool EnablePasswordReset;
{
   get { return m_EnablePasswordReset; }
}

defines a read-only property, maybe the base class author considered a bad thing allowing public write access to the variable.

I write a function that passes a string parameter to my ws and return the hash code of that parameter.
But when I compare it to the hash code of the original string in my client-side code, they were not equal.
Could anybody help me please?

WS Code:

[WebMethod]<br />
public int MyWebFunction(string data)<br />
{<br />
   int retVal = data.GetHashCode();<br />
<br />
   ... rest of my code ...<br />
<br />
   return retVal;<br />
}

Client-Side Code:

public bool DataUploader(string data)<br />
{<br />
   bool retVal;<br />
   int hashCode;<br />
   <br />
   MyWebService ws = new MyWebService();<br />
   hashCode = ws.MyWebFunction(data);<br />
<br />
   if (hashCode == data.GetHashCode())<br />
   {<br />
      retVal = true;<br />
   }<br />
   else<br />
   {<br />
      retVal = false;<br />
   }<br />
<br />
   return retVal;<br />
}

Why does it always returns false?

I'll make sure they remember my name a hundred years from now!

There are two possibilities:

- the strings are NOT equal.
- the hashing is different; please read the remarks on MSDN about String.GetHashCode()

Apparently the string is the cause of my problem.
Using the same web method, I run these codes which return two different results.

Returns true:

public void DoUpload()<br />
{<br />
   string data = "This is my string to upload.";<br />
<br />
   UploadData(data);<br />
}

Returns false:

public void DoUpload(string cmd, string conn)<br />
{<br />
   DataSet ds = new DataSet();<br />
   OleDbDataAdapter oAdapter = new OleDbDataAdapter(cmd, conn);<br />
<br />
   oAdapter.Fill(ds);<br />
<br />
   string data = ds.GetXml();<br />
<br />
   UploadData(data);<br />
}

How could that happen? What's the difference between those two string?
I couldn't find any reason why the first code returns true while the other returns false...

I'll make sure they remember my name a hundred years from now!

Hi,

GetXml() returns a structured text with < and > signs and everything,
it will not return "This is my string to upload."

I am not familiar with databases nor XML, but I think we established your
two strings ARE different. You should have looked at the strings themselves
in the first place !

Smile | :)
