I have no experience with Exchange Server myself but there should be some option to make the users login to send mail.

I have only used CMailServer and Kerio Mailserver and they have this option.

I loaded up a DataSet from an SQL table and was able to read it within the class in which I loaded the ds. However when I try to call the data from another class there is no data in the ds.

Please help,
Michael

I have 2 pieces of code one for datasets and the other a class in which I have a similar problem, I did not include all of the code but the general idea is there. I will place the second in a different thread. Note that some of the syntax comes from a program called OleDBProNet for loading data from a database though this should not matter see where I can read data in "***".

Class1
{
DataSet_I dsI = new DataSet_I();
DataSet_I.BSecDataDataTable BSD = new DataSet_I.BSecDataDataTable();

public void buttonFillDataTables_Click(object sender, EventArgs e)
{
if (checkBoxOleDBProNet.Checked == true)
{
if (checkBoxFilldsIDataTables.Checked == true) FilldsI_DataTablesOleDBProNet();

string strGroup = BSD[200].strGroup;

******* Data does not show here line above*****
}
}
}

Class2
{
DataSet_I dsI = new DataSet_I();
DataSet_I.BSecDataDataTable BSD = new DataSet_I.BSecDataDataTable();

FilldsI_DataTablesOleDBProNet();
{
ShowRowset();
string strGroup = BSD[200].strGroup; ******* Data shows here *****
}

public void ShowRowset()
{
Rowset.MoveFirst();
while (!Rowset.IsEOF)
{
BSD.NewBSecDataRow();
BSD.Rows.Add(nUseRecNumID);

if (Rowset.GetData(1) != null) BSD[nUseRecNumID].nRecNumID = (Int32)Rowset.GetData(1);

Rowset.MoveNext();
}
}
}
}

}
}
}

{
private NameInfoCS[] NameInfoArray = new NameInfoCS[100];

******* if I load data from FillNamesInfoArrayCS here there is no problem, but if I load FillNamesInfoArrayCS from outside of this class and then call this class the class has no data in it. “info.” Below shows as null, “NameInfoCS info in NameInfoArray” error message says I must use new ****************

I remember seeing this article a few weeks ago that seems appropriate, I wouldn't recommend using it for a multiplayer game as punkbuster,etc might class it as a cheat.

Operator overloading

I am working on a project in C# that involves some rather convoluted formulas to calculate values. The resulting code has been very difficult to write and even harder to read/debug. What I want to do is overload some operators to make the math a bit quicker to write and easer to read. (Especially since I know that some of these formulas will change in the future)
For example; I would rather do something like “10^(somevariable* somethingelse)” than “math.pow(10, (somevariable* somethingelse)” since things like this are often buried deeper in a more complicated formula. [I have at least one formula involving 12 operators, 3 of them are raising part of the equation to the power of another part]

I have looked up Operator Overloading and they all refer to using it on user defined classes or UDT’s. There must be an easer way.

Write it in BASIC?

Make a UDT... "just because"? (It's a worthwhile exercise.)

In my http://www.codeproject.com/csharp/PIEBALDTypesRational.asp[^] I use ^ for Power, it just feels more natural to me.

Thanks for the link. I will see if it helps.

You could abuse the XOR operator ^ by wrapping your numbers in a struct with overloaded operators.

You cannot introduce new operators, but you can do something similar with C# 3.0: you can go from the prefix notation "Math.Pow(b, e)" to the infix notation "b.Pow(e)" by defining an extension method.

static class ExtensionMethods
{
  public static double Pow(this double b, double e)
  {
    return Math.Pow(b, e);
  }
}

Resizable right to left windows form

I have made a windows. added toolStripContainer and added a Menustrip and toolstrip to the Toppanel and added a statusstrip to bottom panel of StripContainer.

Then I set the Dock property of toolstripContainer to Fill. and set the Anchor property of toolstrip to Top,Right.

Now my problem is Just the toolstrip.

When I resize my form the Statusbar and Menu just work fine but the toolstrip stays in its original place.

Any Ideas?

Is there a way to draw a new line when something is triggered? Thanks in advance, and I hope that doesn't confuse anyone...

Didn't confuse me. It's crystal clear that you posted a completely ambiguous and utterly useless message.

Also the answer to your question is, yes.

We don't, or at least I don't, know your question is dumb because you didn't put any specific information in your post so we/I don't know what your question is. For instance when you said "draw a new line" O'Hanlon is sure you want to draw a graphic line, but I've been in these forums long enough to know you might mean a text new line as in carriage return / line feed, and that might be in a window control like a multi-line text box or a Grid or a ListView or even a console. so I'm not making any such assumption. If you want to specify "what event" and what you mean by "new line" I might have experience that could help.

Ahhh, but I've answered enough of his questions to know that he generally asks about graphics questions.
