Hi,
apps in IIS are running under a different account (ASPNET for IIS5, NETWORKSERVICE for above). You could impersonate your process.start with using the properties username and password.

add GridView to your page. add TemplateField to the GridView and add hyperlink control to the item template
<asp:GridView ID="grdUsers" Width="100%" runat="server" AllowPaging="True" AutoGenerateColumns="False" PageSize="15" AutoGenerateEditButton="True" OnRowDataBound="grd_RowDataBound" >
<Columns>
<asp:TemplateField HeaderText="hyperlink">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server">HyperLink</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
In row databound you can initialize NavigateUrl Property. as below
protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink Hlink =(HyperLink) e.Row.FindControl("HyperLink1");
if (Hlink != null)
{
Hlink.NavigateUrl = "http://www.google.com";
Hlink.Target = "_blank";
Hlink.Text = "Google";
}
}
}

I am woring on a scheduler application in asp.net with c#.
in this application i have to show popup on scheduled time and date.
scheduled time and date store in sql server table and popup contains.
can any one help me how can i open popup on specified date and time.
thanks

through window service u can do it. But will not be web application.
because to open the pop up the application should be in running state.
and we can not ensure a web application is in running state.
for this u can put the timer in your application.
pick the time from database.
then calculate the time span with system Time.
and Initialize the timer Tick property.
start the timer.
and pop up the window on Timer_tick Event.

Read Records one by one from the sheet and insert it into the desired table. the below function will help you in returning table from the Excel Sheet but the sheet name should be Sheet1. if change ..then change the code i have highlighted with underline(bold)
public DataTable getDataFromXLS(string strFilePath)
{
try
{
string strConnectionString = string.Empty;
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFilePath + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection cnCSV = new OleDbConnection(strConnectionString);
cnCSV.Open();
OleDbCommand cmdSelect = new OleDbCommand(@"SELECT * FROM [Sheet1$]", cnCSV);
OleDbDataAdapter daCSV = new OleDbDataAdapter();
daCSV.SelectCommand = cmdSelect;
DataTable dtCSV = new DataTable();
daCSV.Fill(dtCSV);
cnCSV.Close();
daCSV = null;
return dtCSV;
}
catch (Exception ex)
{
return null;
}
finally { }
}

I have a text box and a set of checkboxes in my form. The textbox is dynamically created.
There is a postback event on the textbox as OnTextChangedEvent and I am checking for a condition in the database with the text entered in textbox.
The issue is whenever the OnTextChangedEvent fires and if the user checks any of the checkboxes, the checkbox is getting cleared. Obviously, this is the nature of web application.
I want to know, whether there is any way to preserve the checked state of checkbox even after postback. I couldn't use the updatepanel because it is dynamically created textbox. I'm just using a placeholder for that. I don't want to place a button next to that. Because then, I need to track whether the user has to click the button etc.
Is there anyway to put the code only in textchange event and keep the changes in other controls without using the update panel?
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

Are you generating textboxes inside gridview control OR in table.?
if you are using the gridview find the control by ControlType
if the control is textbox then get its text.
foreach (GridViewRow row in grdName.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
foreach (Control ctrl in row.Controls)
{
if (ctrl is TextBox)
{
TextBox txt = (TextBox)ctrl;
string str = txt.Text;
}
}
}
}
Get the text as above.

i have tried the below code and i am getting the text from the text box.
i have generated the Textboxes in page_Load
and accessed the textbox text on button_Click
<table>
<tr>
<td colspan="2">
<asp:Panel ID="Panel1" runat="server" Height="200px" Width="125px">
</asp:Panel>
</td>
</tr>
<tr>
<td style="width: 100px">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></td>
<td style="width: 100px">
</td>
</tr>
</table>
Code.
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 0; i < 4; i++)
{
TextBox t = new TextBox();
t.Width = Unit.Pixel(160);
t.Height = Unit.Pixel(22);
Panel1.Controls.Add(t);
}
}
protected void Button1_Click(object sender, EventArgs e)
{
string str = "";
foreach (Control ctrl in Panel1.Controls)
{
if (ctrl is TextBox)
{
TextBox t = (TextBox)ctrl;
