I knew someone would call me out on this. It all depends on the context really; if we're talking about precision, yes, they are obviously not the same.
true. I mainly included it since I wasn't sure what the OP wanted, and wanted to epxlain why the class was doing what it was and check for potential side effects instead of assuming it was a 'double but keeps empty decimal places' and then getting burned over it enforcing SF, or the like.

The problem is that there is no single format that will achieve your goal
Say you have 88.0 and 88888.888
Console.WriteLine("{0 ##}", num)
will give you
88.0
88888.888
the problem is that if you have another number of finer precision, say 99.1234, it will be rounded to 99.124.
If you use the general format g
Console.WriteLine("{0:g}", num)
then you will get
88
88888.888
99.1234
If you have a hard need to display 88 as 88.0 then you will probably need to use two format strings
Dim nums() As Double = {88, 88888.888}
Dim numFmt As String
For Each num As Double In nums
Dim tmpNum As Double = System.Math.Abs(num)
If (System.Math.Floor(tmpNum) = tmpNum) Then
numFmt = "#.0"
Else
numFmt = "g"
End If
Dim exprFmt As String = "{0:" & numFmt & "}"
Console.WriteLine(exprFmt)
Console.WriteLine(String.Format(exprFmt, num))
Next
End Sub
NOTE: When testing this, it works well for Doubles but not singles. Don't know why

Well! Dears.
i have an mdi form in which i open differnet child forms . when both parent and child are maximized its ok but when i restore the MDI parent form it disturbs the layout of Child form that was Maximized in MDI. What i want is that when i restore MDI form it doesnt disturb the layout design of Child form instead it (MDI form) gets Horizantal and vertical scroll bar keeping the Child Form Maximized and undisturbed. How to do that.
Thnx in Advance.

If you're asking how to automatically get scrollbars to some control, look at System.Windows.Forms.ScrollableControl. When some control added to a ScrollableControl extends beyond the visible portion of the ScrollableControl, scrollbars will automatically appear.

cnSQL = new SqlConnection(Connectionstring);<br />
cnSQL.Open();<br />
cmSQL = new SqlCommand(strSQL, cnSQL);<br />
cmSQL.ExecuteNonQuery();<br />
cnSQL.Close();<br />
cmSQL.Dispose();<br />
cnSQL.Dispose();<br />
} <br />
catch(SqlException e)<br />

MessageBox.Show(e.Message, "Error");<br />

Don't do that. You're opening yourself up to SQL injection attacks[^]. I showed you the proper way to do it in my last reply (by using SqlParameter objects). If you follow that course of action, you won't get the error.

No problem, english is not my first language either. I just hope you are not angry at me, I couldn't resist doing the joke. 
I guess you know what a GUID is...

Areff,
If its a windows app use the backgroundWorker control, alternatively :
Using System.Threading;
Thread myThread = new Thread(new ThreadStart(myMethod));
Thread.Sleep(1000); //Sleep for 1 second

Hi Evry body.

What particular information about them do you want, that the documentation does not tell you?
Or, how about some code to show us where you are having problems in understanding how to use Seek on a stream?
|
|
|
|
|
[Serializable()]<br />
public struct Record<br />
{<br />
public string name;
public string Lname;
public int Id;
public int Lid;
public byte Grade;
public string Lsname;
}<br />
<br />
<br />
public static Record Load(string Fname)<br />
{<br />
Stream InStream = File.OpenRead(Fname);<br />
BinaryFormatter DeSerializer = new BinaryFormatter();<br />
<br />
<br />
Record LoadClass = (Record)(DeSerializer.Deserialize(InStream));<br />
InStream.Close();<br />
return LoadClass;<br />
}
I want search in file to find a special struct(record)
I hope you understand me.
