To print two or more pages -even if they contain different data-, you should ruse a single PrintDocument object. In the PrintDocument.PrintPage event set e.HasMorePages = true, until you print al the data you want.
Revise the C# articles - printing section[^] for more details.

Redim multiD-Array

Since Redim does not exist in C#, How do I convert this in C#?

Dim basePoints() As Double
ReDim basePoints(AUTO_PTS - 1, 1)

Use one of the Collection classes which is designed for better array handling. Take a look at classes like the ArrayList to see how they help.

There is no equivalent. You can do it yourself with something like this (unchecked, but you get the idea):

double[] NewBasePoints = new double[newsize + 1];
if (thisArray != null)
  System.Array.Copy(thisArray, NewBasePoints, System.Math.Min(thisArray.Length, NewBasePoints.Length));
BasePoints = NewBasePoints;

You're thinking of 'ReDim Preserve'.
The OP was dealing with the simpler 'ReDim'.

(via Instant C#)

double[] basePoints = null;
basePoints = new double[AUTO_PTS,2];

ReDim Preserve is a little trickier, but also has a C# equivalent.

Control layout, form resizing (Windows Forms)

Hi All,

I'm trying to create a resizable form with a little bit of auto layout.

Basically I have 7 square buttons grouped into a panel. These buttons must never be split up with any auto layout code.

To the right of the buttons I have a trackbar control. I want the trackbar to grow and shrink as the window gets wider/narrower, but, when the shrinkage would result in the trackbar being below a minimum size (in fact, the width of the button containing panel), i want it to drop to below the buttons.

This image shows my controls - here

Can this be easily done with built in winforms stuff? or must I implement it the long way with various resize event handlers and manual repositioning code? I'm hoping to leverage AutoLayoutPanel - because I will have other controls on the form too, eventually.

Thanks

Jon

Check out the FlowLayoutPanel control. It dynamically adjusts the controls within it to fit, and as long as you group things using panels/groupboxes/etc, they'll stay together.

What's deal with
treeView1.Nodes.Reverse

'System.Windows.Forms.TreeNodeCollection' does not contain a definition for 'Reverse'

What's the trick to reverse enum a treeview?
Thanks

I need to remove nodes that don't hit a search query, and leave the nodes and their parents.

Simple formating question with ToString()

I am new to c# so please bare with me...and not laugh to hard at my question.

I can't get onto the MSDN site and since my help menu isn't working correctly I figured I would post my question here.

I was trying to see if there was a way to specify the precision while using double.ToString()? I have a double that returns to me a double with 10 digits after the decimal. I would like to just have it return 3 digits after the decimal.

Do I have to manipulate it using the string.Format or is there a way to do it in the ToString()?

Thanks in advance.

Try double.ToString("F"), which is uses the same format specifiers as String.Format.

[edit]Sorry, I missed the "3 decimal places" bit. As was pointed out, you want to do ToString("F3") instead.[/edit]

Use the formatting string "F3" to get three decimals.

The String.Format method uses the same formatting style as the ToString method. String.Format("{0:F3}", f) produces the same result as f.ToString("F3").

Hello all,

i am new to C# and there is something i can't get to work, so i a requesting your help !

simple code :

namespace ConsoleApplication1
{
    class Father
    {
        public Father()
        {
            System.Console.WriteLine("Build Father");
        }
        public void Something()
        {
            System.Console.WriteLine("Father : Something");
            SomethingElse();

        }
        public void SomethingElse()
        {
            System.Console.WriteLine("Father : SomethingElse");
        }

    }

    class Son : Father
    {
        public Son()
        {
            System.Console.WriteLine("Build Son");
        }

        public new void SomethingElse()
        {
            System.Console.WriteLine("Son : SomethingElse");
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            Son s = new Son();
            s.Something();            
        }
    }
}

this simple code displays "Father : SomethingElse" at the console.
How to get "Son : SomethingElse" at the console without rewriting Son.Something() ?

Many thanks for your help !

Just declare SomethingElse as a virtual function in Father and override it in the Son class.

class Father
{
   public virtual void Something() {...}
}

class Son : Father
{
   public override void Something() {...}
}
