How would you represent INF or NaN as a Decimal? And as leppie said, floating point types cover a wider range than Decimal.
Double.MaxValue = 1.79769313486232E+308
Single.MaxValue = 3.402823E+38
Decimal.MaxValue = 79228162514264337593543950335

My mistake, Eslam! Float has less precision, but broader range.

CollectionEditor Owner/Parent form

I am trying to get the owner/parent form of my CollectionEditor. I have tried looking in:

CreateCollectionForm()

And checking the return values properties such as Owner/Parent, but they are set to null.

Does anyone know how to do this?, and if its not possible via the CollectionEditor, how would i do this via P/Invoke as i am guessing this would be possible...

Regards,
Gareth.

DirectoryInfo.GetFiles should have an overload which takes a pattern also right?

You could use a regular expression to extract the year, month and day of the logfile using this regex:

[^\d]+(?<year>\d\d)(?<month>\d\d)(?<day>\d\d)\.log

Custom Windows Controls

11-Jun-08 1:20

Hi all,

I am developing some custom windows controls and I want every control to be resized when used on the windows form. For example if there is a text box the user can extend the length by just extendeing the legnth of the control. I cannot do this succesfully at then moment I have tried to set AutoSize to true and the AutoSizeMode to GrowAndShrink but it doesn't work.

Do you have any examples?

Thanks in Advance

Tony

Here is my code for the control

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

namespace UserControls.UIControls
{
public partial class LabelledText : UserControl
{
public delegate void EventHandler(Object sender, EventArgs e);
public event EventHandler onGetFocus;
public event EventHandler onLostFocus;

public LabelledText()
{
InitializeComponent();
}

public string LabelText
{
get
{
return lbl.Text;
}
set
{
lbl.Text = value;
}
}
public ContentAlignment LabelAlign
{
get
{
return lbl.TextAlign;
}
set
{
lbl.TextAlign = value;
}
}
public string TextBoxText
{
get
{
return txt.Text;
}
set
{
txt.Text = value;
}
}
public HorizontalAlignment TextBoxAlign
{
get
{
return txt.TextAlign;
}
set
{
txt.TextAlign = value;
}
}
private void LabelledText_Load(object sender, EventArgs e)
{
txt.BackColor = System.Drawing.SystemColors.Control;
}

private void txt_Leave(object sender, EventArgs e)
{
txt.BackColor = System.Drawing.SystemColors.Control;
}

private void txt_Enter(object sender, EventArgs e)
{
txt.BackColor = System.Drawing.Color.White;
}
}
}

Hi Tony,
Just Use Following Code in you Control.

 private void UserControl1_Load(object sender, EventArgs e)<br />
        {<br />
            textBox1.Width = this.Width;<br />
        }<br />
<br />
       <br />
        private void UserControl1_Resize(object sender, EventArgs e)<br />
        {<br />
            textBox1.Width = this.Width; <br />
        }

Note : Change Control Name According to your control

Let me know when done !!!

Thanks Abhijit that works fine.

However I have a label on the left of the textbox which I want the user to extend it. Also I want the label to get extended automatically when typing long text into it. For example if the text on the label is long like 'International Accounts:' the label should be extended to the size of the text in order to display the whole text.

Thanks in advance

In the designer if you select the text box and look in the properties grid there is one called Anchor in the Layout section. You can set which sides to anchor and when the form is resized the control will try to stay the same distance from the edge. However, I don't think a TextBox will stretch up and down unless you have Multiline set to true.

I don't know if it can be hidden - but the AllowScriptChange property will not allow it to be changed if set to false.
