message box problem - ASP.NET Discussion Boards

Ya i am creating objects on server. I am pasting the code for your refrence.

Excel.Application ExlApp;
Excel.Workbook ExlBook;
Excel.Worksheet ExlSheet;

DataTable Dt = new DataTable();
SqlConnection ConnObj;

void GenerateExcelSheet()
{
try
{
ConnObj = new SqlConnection("Server =.;database=parnam;user id=sa;password=");

ExlApp = new Excel.ApplicationClass();
//System.Globalization.CultureInfo OldCL = System.Threading.Thread.CurrentThread.CurrentCulture;
//System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
ExlBook = ExlApp.Workbooks.Add(Type.Missing);
ExlApp.Visible = true;
ExlBook.Application.Visible = true;
//ExlSheet = (Excel.Worksheet)ExlBook.Worksheets[1];
ExlSheet = (Excel.Worksheet)ExlBook.ActiveSheet;
ExlSheet.Name = "Report";

string SQL = "select society_code, society_name,shift_date,shift,round (fat,2),clr,snf,milk_qty,totalamount,deductamount,netamount from trucksheet";
// ConnObj = new SqlConnection(ConfigurationSettings.AppSettings["cn"]);
ConnObj.Open();
SqlDataAdapter Da = new SqlDataAdapter(SQL, ConnObj);
DataTable Dt = new DataTable();
Da.Fill(Dt);
ConnObj.Close();
Da.Dispose();
for (int i = 1; i <= 10; i++)
{
((Excel.Range)ExlSheet.Cells[1, i]).Font.Bold = true;
}
((Excel.Range)ExlSheet.Cells[1, 1]).Value2 = "Society Code";
((Excel.Range)ExlSheet.Cells[1, 2]).Value2 = "Society Name";
((Excel.Range)ExlSheet.Cells[1, 3]).Value2 = "Shift Date";
((Excel.Range)ExlSheet.Cells[1, 4]).Value2 = "Shift";
((Excel.Range)ExlSheet.Cells[1, 5]).Value2 = "F.A.T";
((Excel.Range)ExlSheet.Cells[1, 6]).Value2 = "C.L.R";
((Excel.Range)ExlSheet.Cells[1, 7]).Value2 = "S.N.F";
((Excel.Range)ExlSheet.Cells[1, 8]).Value2 = "Milk Quantity";
((Excel.Range)ExlSheet.Cells[1, 9]).Value2 = "Total Amount";
((Excel.Range)ExlSheet.Cells[1, 10]).Value2 = "Deduct Amount";
((Excel.Range)ExlSheet.Cells[1, 11]).Value2 = "Net Amount";

for (int r = 2, i = 0; r < Dt.Rows.Count; r++, i++)
{
for (int c = 1, j = 0; c <= Dt.Columns.Count; c++, j++)
{
// ((Excel.Range)ExlSheet.Cells[k, 3]).Value2 = DtAcc.Rows[0][0].ToString();
((Excel.Range)ExlSheet.Cells[r, c]).Value2 = Dt.Rows[i][j].ToString();
}

}
}
catch (Exception ex)
{
Response.Write(ex.Message);
}

This will create and open an excel spreadsheet on your server, which has a couple of problems:

1. Clients on remote machines aren't going to be able to see this, it's on the server.

2. You don't close the spreadsheet. Trust me (from experience as a junior dev), it doesn't take too many instances of excel to be open before you bring a server to its knees.

If you want to display an excel spreadsheet to a client, you can display your data in an html table and then set appropriate headers to tell the browser what you are downloading is Excel. This should then enable the user to view it in Excel.

Thanks Sir.

I will try.

I'm working on a web app for work using asp.net 2.0 that will be accessible only on our intranet. I was wondering if there is a way check for installed software on the client machines, and even interact with the client software via asp.net 2.0(+). Assuming also that all the machines are running windows xp SP2 or later. For example ... updating the outlook address book.

You may need to have an ActiveX Control to achieve that. The default JavaScript or HTML may not have that privilege to interact with the local machine (system) settings.

ok ... I've never done any ActiveX programming before. Any suggestions on where to start? I already know what functionality I need. Can I do activeX in .Net ?

I got this[^], when I searched in google.

I have a messagebox , which i call on the form load in the java script using the onload fucntion in the body tag.
when the form loads it automatically gets invoked.
i have a button too, on clicking the button , again the message box gets appeared.How i should avooid it.

<head runat="server"><br />
    <script language="javascript" type="text/javascript"><br />
        var a;<br />
        a = false;<br />
        function abc()<br />
        {<br />
            if(!a)<br />
            {<br />
                alert('hi');<br />
            }<br />
            <br />
        }<br />
    </script><br />
    <title>Untitled Page</title><br />
</head><br />
<body onload="return abc();"><br />
    <form id="form1" runat="server"><br />
    <div><br />
        <asp:Button ID="Button1" runat="server" Text="Button" /></div><br />
    </form><br />
</body>

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Since it is a ASP:Button (Server Control), I guess, it is posting back and after postback, the page gets painted afresh causing the web browser to invoke the onLoad event handler.

Hello,

I have datatable and it is populated with some values.
Is it possible to add a column in an exiting datatable now with a auto increment values?

I am trying like this but it does'nt wotk

dslistItems1.Tables[0].Columns.Add("ID", Type.GetType("System.Int32"));
DataColumn[] pk = new DataColumn[1];
pk[0] = dslistItems1.Tables[0].Columns["ID"];
//dslistItems1.Tables[0].PrimaryKey = pk;
dslistItems1.Tables[0].Columns["ID"].AutoIncrement = true;
dslistItems1.Tables[0].Columns["ID"].AutoIncrementSeed = 1;
dslistItems1.Tables[0].Columns["ID"].ReadOnly = true;

This code doesn't populate the values in the column

Regards,
Pavas

You are trying to use this code to create a new column in the database? The DataSet is a disconnected, in-memory representation of the database, if you want to add a column into the actual database table you'll need to issue an ALTER table sql statement.

No I do not want to add it to database table. I have a populated datatable and then I want to add an autoincrement datacolumn to a data table.

The purpose is I want to create relations among other datatables present in the dataset.

Pavas

Maybe this will help
