Hello.
I’m new to this forum and also learning the C# language.
I have a question about type conversion in C#.
In the following sentence, the compiler gives me an error because it cannot implicitly convert a double literal to an int type.
int i = 45.7;
But in the following sentence the compiler does not generate any error.
short x = 45;
every literal has a type. So 45 is a literal constant of type int and I’m trying to assign it to x variable of type short. According to this page, conversion from int to short must be explicit but it is not ! why ?

Because 45 falls in the range of a short. No conversion is necessary

Hi Mani_Amoozadeh,
when you cast as short x = 45;
45 falls in the range of a short.Range for short is -32,768 to 32,767 and hence it do not give any cast error.
But when you explicitly try following
int j = 45;
short x = j;
it gives you cast error because you try to convert value of integer to short.
Thanks

It looks to me like google will at least explain what those algorithms are. So, how about just writing them yourself, and perhaps writing an article here for the next person that needs them ?

Hi
in my first db (access 2003), i have some tables which has Text columns as PK, my app create new GUID and convert it to Text, then save back to access db.
Now i want to transfer data from access to sql server, to do this, i must load data from access, convert PK from Text to GUID, then save back to sql server database.
i use this code to load original data and convert PK from Text to GUID :
this.personsTableAdapter1.Fill(this.testDataSet1.Persons);
DataTable dtImported = this.testDataSet1.Persons.Clone();
dtImported.Columns["PersonID"].DataType = typeof(Guid);
foreach (TestDataSet.PersonsRow row in this.testDataSet1.Persons.Rows)
{
Guid g = new Guid(row.PersonID);
dtImported.Rows.Add(new object[] { g, row.PersonName });
}
but the following error message thrown in above line of code :
Cannot set column 'PersonID'. The value violates the MaxLength limit of this column.
can anyBody help me ?
Note : first, i convert my data from sql server to access 2003 by ssis package. now i want to transfer it again from access 2003 to sql server.

Well, I assume this means that a GUID takes up more room than the datatype in your original table. You're cloning the table, so you're going to have columns with the same size/type as you did before, unlike your SQL DB.

Is this WPF code ? Where is your timeline associated with your media player ?

It looks like WPF.
You are creating a MediaTimeline with repeat enabled but then you aren't using it.

Yes.
public class Program
{
static void Main(string[] args)
{
HTTPGet req = new HTTPGet();
req.Request("http://www.google.com");
Console.WriteLine(req.StatusLine);
Console.WriteLine(req.ResponseTime);
}
}

You could probably use the System.Net.WebRequest class[^], setting the Method property to "GET". There's a code snippet on the MSDN page I linked to which shows you roughly how to use it

do a search for HttpWebRequest and its counterpart HttpWebResponse
(thats one way, afaik HttpWebRequest is quite customisable)
