they are in a different class named baglanti

public GroupBox gb;

public void gbColor(GroupBox gbT)
{
gb = gbT;
gb.MouseClick += new MouseEventHandler(gb_click);
}

private void gb_click(object sender, EventArgs e)
{
gb.BackColor = Color.Red;
}
in other class i use this to add gb_click event to the groupboxes

clsBgl.gbColor(groupBox1);
clsBgl.gbColor(groupBox2);
clsBgl.gbColor(groupBox3);

you are overwriting the variable (gb) so the behavior is expected

instead create a new instance of the class for every groupbox

gb1 = new clsgbl
gb1.gbcolor(groupbox1)
gb2 = new clsgbl
gb2.gbcolor(groupbox2)
gb3 = new clsgbl
gb3.gbcolor(groupbox3)

(not shure about the syntax been a while since I done c#)

Personlisation and Shared View

Hi,

I have the following scenario for a social networking site I am working on.

Users create accounts in the site and then can edit their details etc. They can also have their public facing page (which will be seen by others when they click on their name etc).

Example User A signs up and then creates his public page e.g. site.aspx

I want that the user can customise this page using webparts and .net personalisation so that his changes made (like themes or webparts) can be seen by User B.

I first got it working by letting the user modify his own page but the changes reflected only when he logged on.

Then I got it working by using the following:

<webParts>
<personalization>
<authorization>
<allow users="*"
verbs="enterSharedScope"/>
</authorization>
</personalization>
</webParts>

However, with the second approach now anyone could edit his page and save the shared view as all users will have permissions to amed their pages.

I am trying a third solution by creating folders for users and then copying a default.aspx and web.config file in it, thinking there may be a way this way... but am stuck.

The users are created using asp.net membership with additional details held in custom table.

Any ideas on how to implement this functionality of user customisable page where customisations can be seen by others as well as him.

Thanks,

Adeel

   I have started a thread in the SQL Forum asking about experiences others have had using CLR-based SPs in SQL Server. Rather than do a complete cross-post and end up with two threads, I would like to ask any C# developers here that have something to offer to the discussion to please go over there and contribute:

"inhereting" a struct?

Vodstok23-Oct-08 2:16

Vodstok

23-Oct-08 2:16

I have some classes I am writing that represent units of measurement, and I am trying to do this:

each unit (Inch, Foot, Yard) is essentially a decimal, but has different properties, eg. a foot has 12 inches, a yard has 3 "foots" and 36 inches, so on. Is there a way to say "this class is a decimal" in a way similar to inheretence?

I have tried using the same structure of a decimal, including all of the interfaces it inherets, but that was a god awful mess. Any ideas/suggestions?

I would imagine that creating wrappers around the decimal struct would do the job. I did a similar thing for binary, octal and hexadecimal with an int here[^].

[Edit] I found this interesting so I've tried a little bit of coding - figured I may as well share it with you! Depending on what you're doing with this data, this may help. This (incomplete but working) struct wraps three ints and does some basic stuff. [/Edit]

public struct Imperial
{
    public static readonly Imperial Empty = new Imperial();
    public Imperial(int inches)
    {
        m_Yards = 0; // Set default values
        m_Feet = 0;
        m_Inches = 0;
        if (inches != 0)
        {
            m_Yards = inches / 36;
            int remainder = inches % (m_Yards * 36);
            if (remainder != 0)
            {
                m_Feet = remainder / 12;
                if (m_Feet != 0)
                    m_Inches = remainder % (m_Feet * 12);
                else
                    m_Inches = remainder;
            }
        }
    }
    public Imperial(int yards, int feet, int inches)
    {
        m_Yards = yards;
        m_Feet = feet;
        m_Inches = inches;
    }
    public static implicit operator Imperial(int value)
    {
        return new Imperial(value);
    }
    public static Imperial operator +(Imperial value1, Imperial value2)
    {
        return new Imperial(value1.GetTotalInches() + value2.GetTotalInches());
    }
    private int m_Yards;
    private int m_Feet;
    private int m_Inches;
    public int Yards
    {
        get { return m_Yards; }
    }
    public int Feet
    {
        get { return m_Feet; }
    }
    public int Inches
    {
        get { return m_Inches; }
    }
    public int GetTotalInches()
    {
        return ((m_Yards * 36) + (m_Feet * 12) + m_Inches);
    }
    public static Imperial MillimetersToImperial(int millimeters)
    {
        return new Imperial((int)(millimeters * 0.0393700787));
    }
    public override string ToString()
    {
        return string.Format("{0} yards, {1} feet, {2} inches", m_Yards, m_Feet, m_Inches);
    }
}

Awesome. The method mentione din the article is the one i went with. I created a class that handles the basics like converting and constructors, then inheret it with the other classes. Works like a charm Big Grin | :-D

If you have a logical way of doing the conversion, you could add implicit conversions to and from a numerical data type. That way you can assign a numerical value to a measurement variable, and use a measurement value where a numerical value is required. (I'm not sure that Decimal is the right choise of numerical data type though. A double might be a better fit.)

However, it looks like you would have to specify the unit for the value to make sense as a measurement?

Despite everything, the person most likely to be fooling you next is yourself.

Your message title is misleading.

You cannot "inherit" a struct.

RichTextBox RightClick [modified]

V.23-Oct-08 2:10

23-Oct-08 2:10

[EDIT]We have a workaround now, because the workflow would result in other errors Smile | :)

[/EDIT]

I should 'simulate' a left-click or set the cursor to the position of the mouse, when right clicking (popup contextmenu) is occuring.

I tried mainly this:

mea = new MouseEventArgs(MouseButtons.Left, e.Clicks, e.X, e.Y, e.Delta);
OnMouseClick(mea);

but that doesn't work. I also tried to move my cursor position:

Cursor.Position = new Point(e.X, e.Y);

but nothing works. My guess is that the context menu is ahead of me although I should think that OnMouseDown would be before the contextmenu request?

How can I do this?

Many thanks !

V.

hi
use
int index = RichTextBox.GetCharIndexFromPoint(Point pt);

to get the position of the char under the mouse.

use
RichTextBox.SelectionStart = index;
RichTextBox.SelectionLength = 0; // maybe this line is not necessary

to move the cursor inside the textbox.
