Hello,

It's a parameterised constructor;
The constructor name has to be equal with the class name!

A class can have more than one constructor:

class FDemo
{
    int x;
 
    //default constructor
    FDemo()
    {
    }

    //parameterized constructor, which takes an int
    FDemo(int i)
    {
        x = i;
    }

}

If you now want to instanciate the class you could use:
FDemo fdemo = new FDemo();
or:
int actValue = 5;
FDemo fdemo = new FDemo(actValue);

All the best,

Martin

Like I said, to instanciate a class;

Or, do you mean, why we use parameterized constructors?

I think you might want to buy a book on OOP, as this is a very fundamental question to understanding it.

Hi,

i can't help you with a blinking form, but what do you think of a blinking notifyIcon? You would just need a timer to change the notifyIcon each second or so.

SSL is Secure Socket Layer, an encryption mechanism used to send information securely on internet. Basically it holds a public key and a private key.

You have to install SSL on IIS. And browse your site through HTTPS protocol. If your web applications really needs to send sensitive information like Credit card numbers, you could use SSL. But it always requires more processing overhead and financial overhead.

Stored procedure is pre-compiled but the class query coding needs to get compiled in run time

For each SQL Command the DBMS will do syntax check and execution plan generation.

For class queries DBMS will do it for each time the query executed, for stored procedures, at the first execution DBMS will do the syntax check and will store the execution plan. So it executing a Stored Procedure is efficient than usual queries.

You can start and stop a windows service using System.ServiceProcess.ServiceController class.

You can see here an example:

Regarding Promotion Code/Copoun Number Generator

Hi
This is Murthy. Anybody has a C# Code
to generate 12 digit Unique Promotion Codes/Coupon Numbers.
Those numbers should not be generated in sequence like 10234, 10235, 10236 etc...
All the numbers should be generated in random and should not be duplicated.

Example:

1. Promotion Codes for Product Discounts.
2. Prepaid Recharge Coupons for Mobile Phones etc.

Thanks
Murthy.

Most likely what you want is for the last digit to be a checksum, so you can verify the codes are genuine. If you need to generate a random sequence, your best bet is to create an int list, and use a random generator to pull numbers out of it at random positions.

How to display image in DataList ?

I have this code in file default.aspx below :

<asp:DataList id="DstAlbum" RepeatColumns="3" RepeatDirection = "Horizontal" BackColor="#FFFFFF" OnItemDataBound="Album_DataList_ItemDataBound"> <ItemTemplate> <tr>
<td><table width="100%" style="WIDTH:100%"> <tr>
<td align="center"><asp:HyperLink id=Album_name NavigateUrl='<%# "AlbumDetail.aspx"+"?"+"id+Album="+Server.UrlEncode(DataBinder.Eval(Container.DataItem, "id_Album").ToString()) +"&" +""%>' style="font-size: 10pt; color: #000000" runat="server"> <%#Convert.ToString(DataBinder.Eval(Container.DataItem, "TenAlbum")) %> </asp:HyperLink> </td></tr>
<tr><td><input type=hidden id=Album_image runat="server" value=<%#Convert.ToString(DataBinder.Eval(Container.DataItem, "AnhBia")) %> NAME="Album_image"></td></tr>
</table></td></tr> </ItemTemplate>
</asp:DataList>

And file default.aspx.cs below :

private void Page_Load(object sender, System.EventArgs e)
{
string strConn = "Integrated Security = SSPI;" + "InitialCatalog=HopNhac_Database;" +
"Data Source=localhost;";
string strSQL = "Select id_Album,TenAlbum,AnhBia From tblAlbum";
SqlDataAdapter dad = new SqlDataAdapter(strSQL,strConn);
DataSet dst = new DataSet();
dad.Fill(dst,"tblAlbum");
DataView Source;
Source = new DataView(dst.Tables[0]);
DstAlbum.DataSource = Source;
DstAlbum.DataBind();
}

public void Album_DataList_ItemDataBound(Object Sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{ ((HyperLink)e.Item.FindControl("Album_name")).Text ="<img border=\"0\" src=\"" + ((DataRowView)e.Item.DataItem )["AnhBia"].ToString() + "\"></td><td valign=\"top\"><table width=\"100%\" style=\"width:100%\"><tr><td style=\"background-color: #FFFFFF; border-style: inset; border-width: 0\"><font style=\"font-size: 10pt; color: #CE7E00; font-weight: bold\"><b>" + ((DataRowView)e.Item.DataItem )["TenAlbum"].ToString() + "</b>";
}
}

When I compiled , it take an error : 'System.Web.UI.Control' does not contain a definition for 'DataItem'.
And that error is Hyperlink at default.aspx file.

somewhere is paradise.

Detecting URL in RichTextBox Control?

wienzzz9-Oct-07 17:23

wienzzz

9-Oct-07 17:23

Hai,

On RichTextBox Control, there's a property "DetectUrls". When the property value is "true" then any word begin with "www." on that richTextBox will be treated as Hyperlink.

my Question :
How do we treat the text on richTextBox as hyperlink manually?
Or, maybe there's any class that we could edit so there will be more word pattern to be treated as hyperlink?

thankz for the information
