string ID;
foreach (GridViewRow gr in GridView1.Rows)

DeptID = int.Parse(ID);
TextBox tx = (TextBox)gr.FindControl("txt1");
insDept.up(DeptID,tx.Text);
BindGrid();
}
}
I gave the above design code and also in button click event above code is given.but when we tried to save it the selected field is updated to empty.what is the reason.

Are you trying to populate/defining value to the GridView on Page Load event?

Try the below code. You get the computer's list in a DataTable.
public DataTable GetComputers
{
DataTable dtComputers = new DataTable("Computers");
DataColumn dc;
DataRow dr;
dc = new DataColumn("ComputerName");
dc.DataType = System.Type.GetType("System.String");
dc.MaxLength = 50;
dtComputers.Columns.Add(dc);
dc = new DataColumn("IPAddress");
dc.DataType = System.Type.GetType("System.String");
dc.MaxLength = 50;
dtComputers.Columns.Add(dc);
Process p = new Process();
p.StartInfo.FileName = @"net.exe";
p.StartInfo.Arguments = "VIEW";
p.StartInfo.CreateNoWindow = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.Start();
p.WaitForExit();
while (!p.StandardOutput.EndOfStream)
{
string readLine = p.StandardOutput.ReadLine();
string computerName = "";
if (readLine.IndexOf("\\") == 0)
{
dr = dtComputers.NewRow();
computerName = readLine.Substring(2, readLine.IndexOf(" ")).Trim();
Console.Write("\n" + computerName);
dr["ComputerName"] = computerName;
dr["IPAddress"] = Dns.GetHostEntry(computerName).AddressList[0];
dtComputers.Rows.Add(dr);
}
}
if (!p.HasExited) p.Kill();
return dtComputers;
}

Hello all. I'm an intermediate programmer, but relatively new to the web end of things and was wondering about the best way to go about scheduling an occasional task to run on the server... say every day or a certain number of hours/minutes.

Windows service is good one for this.

Can you be more specific? How does one go about writing/installing a Windows service on a web server? I am hosted with 1&1, and do not have direct access to IIS.

Hi,
I have developed an ASP.Net Website,
and now I have published it,
in first page there is no code to run, only a login page but when I want to open my website in web a Runtime Error, but yet no code is runned.
it's the first time I upload an asp.net web site.
should I do any changes in my web.config for upload?
my web.config:
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings>
<add name=".." connectionString="Data Source=.;Initial Catalog=..;User ID=..;PWD=.." providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="false">
</compilation>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Windows"/>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>
Best wishes

Hi, i have a rookie question. how do i link asp.net and silverlight so that i can set properties or values on asp.net page and be able to access those values with a silverlight client?
i started a asp.net web application project. then i added a silverlight project. in asp.net, i selected "add silverlight link". at this point, i think i should be able to somehow move any data back and forth between asp and silverlight, and this is where i'm stuck. any suggestions what i can try ?
thanks !!

If you're talking about having a Silverlight object and other server controls on the same ASP.NET page, and have them share data back and forth, I think this proof of concept[^] will point you in the right direction.
If you're talking about having a silverlight component that should communicate with an ASP.NET web service, take a look at this QuickStart tutorial[^].

You can use "Add Silverlight Link" in VS 2008 if you have Silverlight Tool for VS 2008 installed.

No. You won't be able to get the properties of ASP.NET page from Silverlight project. The main reason why we should use "Add Silverlight link" is that ~
1. To prevent the cross-domain error. For example, you won't be able to access the database from Silverlight directly. So, you have to create the webservice for that. then you have to invoke that service to get the data from database. If you are using two different projects for web service and silverlight project, you will get the cross-thread.. So, what we used to do is that we put the webservice in ASP.NET project and add the silverlight link to ASP.NET project.
Let me know if you need more help on Silverlight 1.1 with ASP.NET. I'm willing to help you..

using System.Runtime.InteropServices; //For Marshall
//CODE:::::
Excel.Application oXL;

object oMissing = Missing.Value;
Range oRng;
oXL = new Excel.Application();
oWB = oXL.Workbooks.Open("EXCEL LOCATION", oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);
int TotalSheetsinExcel = 0;
TotalSheetsinExcel = oWB.Sheets.Count - 1;
oSheet = (_Worksheet)oWB.Sheets[1];
Picture pic = (Picture)oSheet.Pictures(1);
//pic object will have PICTURE
//Close Objects
oWB.Save();
oWB.Close(null, null, null);

Hi mavii,
I too worked on Crystal Reports where I didnot do the Procedure as given by you. I used Stored Procedures which is very simple and easy to use. If you require this I will help regarding this.
