Hi,
I have a class file: dbtest and a have create a static public function that returns values from database.
Since its an static public function so i can access it as dbsale.function().
Now I wanted to know the disadvantages of this approach when say there are some 1000 call at a time for this function.
I have searched a lot and found examples of using static public functions but no where I found it to be used for calling a database operation.
Thanks in advance.

I think I can equate this multi-user thing to a multithreaded environment. You can use public static functions, there will be no problem. But if you are using static objects inside your function, then there's a one. There are big chances your static objects get overwritten with calls from other clients. If you are using local objects or instance members inside the function, then there wouldn't be any problem.
This is all a guess. I haven't tried this in Asp.net

Thanks ViNic for your reply.......
Can u focus on the following code is this one is correct?
BinaryTree.cs file inside appcode
public class BinaryTree
{
public static ArrayList dlist = new ArrayList();
public static void FetchDownlineID(long uid)
{
BinaryTree bt = new BinaryTree();
bt = BinaryTree.fetchIdInfo(uid);//fetches user info
if (bt.Aid > 0)
{
dlist.Add(bt.Aid);
BinaryTree.FetchDownlineID(bt.Aid);
}
if (bt.Bid > 0)
{
dlist.Add(bt.Bid);
BinaryTree.FetchDownlineID(bt.Bid);
}
if (bt.Cid > 0)
{
dlist.Add(bt.Cid);
BinaryTree.FetchDownlineID(bt.Cid);
}
}
}
now this function is called on pageload as user's open page & result is bind to gridview...
as follows----------
public partial class User_DownlineLists : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
bindGridView();
}
protected void bindGridView()
{
if (Session["User"] != null)
{
long id = UserDetails.FetchUserId(Session["User"].ToString());
BinaryTree.dlist.Clear();
BinaryTree.FetchDownlineID(id);
Sort();//this function sort list datewise
GridView1.DataSource = BinaryTree.dlist;
GridView1.DataBind();
}
else
{
Response.Redirect("~/Home.aspx");
}
}
}

No, This looks truly bad to me.

You might have read a "rant" from me just above your message. That says why you should not do it. Though every member would create a new object of your BianryTree, it's dlist would be shared.
VijayVishwakarma wrote: if (bt.Aid > 0)
{
dlist.Add(bt.Aid);
When one client does the above code, Another client could potentially execute the below code.
BinaryTree.dlist.Clear();.
You get the idea?

My evet handler is this
protected void GV_Main_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onclick", "onGridViewRowSelected('" + m_iRowIdx.ToString() + "')");
}
m_iRowIdx++;
}
Which perform a selected row color change.This call a java script
Which is like this
< script language="javascript" type="text/javascript> var gridViewCtlId = '<%=GV_Main.ClientID%>';
var gridViewCtl = null;
var curSelRow = null;
function getGridViewControl()
{
if (null == gridViewCtl)
{
gridViewCtl = document.getElementById(gridViewCtlId);
}
}
function onGridViewRowSelected(rowIdx)
{
var selRow = getSelectedRow(rowIdx);
if (curSelRow != null)
{
//curSelRow.style.backgroundColor = '#ffffff';
curSelRow.style.backgroundColor = '';
}
if (null != selRow)
{
curSelRow = selRow;
//curSelRow.style.backgroundColor = '#ff0022';
curSelRow.style.backgroundColor = '#D1DDF1';
}
}
function getSelectedRow(rowIdx)
{
getGridViewControl();
if (null != gridViewCtl)
{
return gridViewCtl.rows[rowIdx];
}
return null;
}
When a run application on dafault page 1 it is work fine ,but as I change page is is not working .Grigview use paging
Please tell me my error or give me a solution.
Thanks

can you tell me if your gridview is in content placeholder? If yes, Check the page source to find the id of the gridview. If u are using content placeholder, then the id of the gridview will change to ctl_01_gridview or something.
So the javascript is not able to find the gridview.
Check this first.

after 3 houres of forum searching im truey lost, i whent on the MSDN and copy pasted there helloworld exampel but its not working eather...
i tryed whith following in my Root web.config (not that i have any sub cfg's now.
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.sample" type="HelloWorldHandler,HelloWorldHandler"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

//context.BeginRequest += new EventHandler(context_BeginRequest);
}
void context_BeginRequest(object sender, EventArgs e)

//HttpApplication app = (HttpApplication)sender;
}
3. Add below code in yr web.config file

Hi,
I have be searching the forum for examples of code that allows you to get the FTP path information for a group of files that have the same file name but different date e.g. file12082009 and add then to a datatable so once I have the file information for each file in the datatable I can then download any new ftp file that is not in the datatable.
Basically every time I download a file I would like the file information only to be added to the datatable but only download files that are not in the datatable.
I currently have code that will download the file from the FTP using vb.net which works fine.

It's easy to do the property, but my brick wall here is using the property as an attribute in the markup tag for that control.
This markup:
tc:TypeUser runat="server" ID="me" DataType="System.Int32"
causes this error:
Cannot create an object of type 'System.Type' from its string representation 'System.Int32' for the 'DataType' property.
