No matter how hard you try, the CLR won't let you raise an event from an object which does not expose that event. That's just the way it is. Why do you want to do that, anyways? Could you not accomplish whatever it is you're attempting to do by calling the method which executes when the DoubleClick event is raised (instead of raising the event)?

I have developed a software that takes text documents as input and after performing a few steps it generates an inverted index....and it takes a little time to do so and i want to display a percentage progress as text label.....and i ve calculated the time taken by each step in this and then changed that time into to percentage and displayed it after the button click.....but the problem now is that when i change the input files this percentage starts to look stupid.....so i want to ask that how can i calculate the percentage wich will work for all inputs..........
Looking forward for help

Okay
That's for sure a bad idea to do the time calculation since for the same file, on different machines of different speeds or even in your own machine when it is busy, times may take shorter or longer....
The idea is simple: you should make get to know the size of the input file (in characters, bytes etc.) and then simply check where you are processisng now... For example if the file is 100 characters long, and you are now processing the 23rd character, you are at 23% of your process....
Hope this could give you the idea....

Sir the real problem is that i m reading about 350 files and i m performing one step at a time ist i read all the files then in the next step i remove the white spaces from it in next step i remove some unecessaray words from this dataset and few more steps like that i m doing it this way that i ist checked the total execution time of the program then i checked that how much time each of these steps take and then i divided that into percent of total time and then in each step i checked on the basis of all the files present and the file already processed......i hope u understand the problem now 
looking forward for help

Are you saying that you are looping through the files for EACH step? If so you are probably executing more loops which in itself will slow down.
Prev poster is correct though, you CANNOT make a decision based upon time of execution, it just won't work for every (many) circumstances.
BTW, I'm still unclear of what you're really trying to do!

what do you mean with table a dataTable object or a database table?
If it is a database witch kind of database and how do you connect with it?
anyway. you can get the label property text and with it do and update if it is database table:
"alter table 'tablename' add column (label.text.toUpper() datatipe(length))"
if you are talking about a datatable is even easier
datatablename.columns.add("label.text");
hopefully it will help you
NOthing by now;)

//i have not tryed the code so it might have some errors but i think you can get the idea
//SQL_COMMANDS (this commands will work only if you have a SQL Database)
//this command will return all the non system tables
SELECT Table_Name AS NOMBRE FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE '
//this will return all the column names from a given database and table
SELECT COLUMN_NAME as column FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME
string Query = "SELECT COLUMN_NAME as column FROM INFORMATION_SCHEMA.columns WHERE TABLE_NAME LIKE 'the_name_of_your_table'
//first you have to get all the column names of your table
Cache = new System.Data.DataSet();
using (SqlConnection Conn = new SqlConnection(this.Conexion))
{
SqlDataAdapter SqlDs = new SqlDataAdapter(Query,Conn);
Conn.Open();
SqlDs.Fill(Cache,NombreTabla);
}
//now you have all the column names and you have to iterate as many times as columns you have creating and adding to your form a lavel
//note that in your case the location will have to be assign dinamicly
foreah(DataRow row in Cache.DataTable["NombreTabla"].rows)
{
System.Windows.Forms.Label MyLabel = new System.Windows.Forms.Label();
MyLabel .Location = new System.Drawing.Point(64, 64);
MyLabel .Name = row[0].tostring();
MyLabel .Size = new System.Drawing.Size(376, 64);
MyLabel .TabIndex = 0;
MyLabel .Text = row[0].tostring();
//here we add the new label to the form
this.controls.add(MyLabel)
}
//i hope the code above can help you

Not an AD expert by any means, but have been doing somework with it lately.
Doing a dsquery server on the command line will return a list of comain controllers for your domain. I think this is a subset of cn=configuration,dc=yourdomain,dc=com. Of course, if you have no DC, that will not work .

Is it have any Optional parameter in C#
If it have, How to declare in a method
Tell me please\\
thanx

|

|

Nope, they took out optional parameters for C#.
Instead you have to make multiple overloaded methods, each for which ever parameters you want to use.
|
|
|
|
|
public void MyMethod() {
// for example you can call your second function
MyMethod(true);
}
public void MyMethod(bool param1) {
// for example you can call your third function
MyMethod(param1, "");
}
public void MyMethod(bool param1, string strParam2) {
// do something
}
now you just can call the method by
MyMethod(); //or
MyMethod(oMyVar); //or
MyMethod(oMyVar, strMyString);
this is a good way to do this.

I've added a table and a couple of textboxes dynamically to my .aspx page.
When I want to loop through the controls on the page, it just displays the text "control", irrespective of how many text boxes were generated.
Here is my loop to display the controls:
protected void btnInsert_Click(object sender, EventArgs e)
{
foreach (Control control in Page.Controls)
{
if (control.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox"))
{
Response.Write("contol " + control.ID + "<br />");
}
}
}
Please can someone help.
Regards,
Brendan

Hi,
Have you verified that whether you are having the TextBox control in Page.Controls, because i have used like this and this is giving me correct result:
foreach (Control control in Page.Controls)
{
if(control.GetType().ToString()=="System.Web.UI.HtmlControls.HtmlForm")
{
for(int i=0; i<control.Controls.Count; i++)
{
if(control.Controls[i].GetType().ToString()=="System.Web.UI.WebControls.TextBox")
{
Response.Write(control.Controls[i].ID + "<br>");
}
}
}
}
Hope this will help you.
Best Regards,

Take a look at how you are adding the TextBoxes. If you're adding them to a panel or some other control that's in the Page.Controls collection, then Page.Controls won't contain your control, but panel1.Controls will (for instance).

Hi,
Something really weird is happeneing here, and I can't explain why.
Let me give you a brief explanation what happens. When the pages loads for the first time it loads all the hub groups into a dropdown control, that's all. Each hub group can have 0, 1, or many hubs. I don't know how many hubs there are per hub group. When the user selects a hub group, it sets a panel to true, and loads all the related hubs, with textboxes. The textboxes are generated automatically. I give the ID of each textbox "txt" plus the ID of the hub (from the database).
This is my code in the .aspx file (just some of it):
<asp:Content id="cntBodyContent" ContentPlaceHolderID="cphBodyContent" Runat="Server">
<h5>Hub Group</h5>
<asp:DropDownList id="cboHubGroup" AutoPostBack="true" OnSelectedIndexChanged="cboHubGroup_SelectedIndexChanged" runat="server" />
<asp:Panel id="pnlHubCommissions" Visible="false" runat="server">
<asp:Table id="tblHubCommRates" BorderWidth="1" Width="100%" runat="server"></asp:Table>
<asp:Button id="btnInsert" Text="Insert" CssClass="FormButton" runat="server" OnClick="btnInsert_Click" />
</asp:Panel>
</asp:Content>
When I generate the textboxes for each hub, this is my code:
string strHubs = string.Empty;
TextBox tb;
List<Hub> lstHubs = Hub.GetHubsByHubGroupID(Int32.Parse(cboHubGroup.SelectedValue));
foreach (Hub h in lstHubs)
{
TableRow tRow = new TableRow();
tblHubCommRates.Rows.Add(tRow);
TableCell tCell1 = new TableCell();
TableCell tCell2 = new TableCell();
tCell1.Text = "<h5>" + h.HubName + "</h5>";
tCell1.Width = Unit.Percentage(15);
tRow.Cells.Add(tCell1);
tb = new TextBox();
tb.ID = "txtHubCommRate" + h.HubID;
tb.Width = Unit.Pixel(44);
tb.MaxLength = 6;
tb.CssClass = "InputText";
tCell2.Controls.Add(tb);
tCell2.Width = Unit.Percentage(85);
tRow.Cells.Add(tCell2);
}
My button event handler:
protected void btnInsert_Click(object sender, EventArgs e)
{
// It does nothing yet
}
Everything displays well, 100% in fact. But this is where I am having my problem. When I click on the buttion, then table with the results generated disappears. Not sure why this happens. This is why I think it can not display the controls, because it is not there. Is there a reason for this??
I hope someone can help. If I have left out something, please let me know. If I can get this to work, then I can think about trying to display the textbox values.
Regards,
ma se
