<br />
Process pro = new Process();<br />
pro.StartInfo.UseShellExecute = false;<br />
pro.StartInfo.RedirectStandardOutput = true;<br />
pro.StartInfo.RedirectStandardError = true;<br />
pro.StartInfo.FileName = "Ping";
pro.StartInfo.Arguments = "ip Address" <br />
pro.Start();<br />

Hope it will help

That would launch the external ping utility. You ought to capture the output of the command. Instead of that, you can simply try the following:

I have difficulty to create a two-column website by ASP.NET, I mean the vertical menu on one column, the main content on the other. But they are on top of each other, even with Div. I don't know how to make them next to each other horizontally. I am new to ASP.NET, could anyone tell me how to create the two-column frame, please?
Much Appreciate if you help

If you want to create the DIV-based layout instead of using table-based layout, you should have good understanding about CSS float.
You can learn about CSS float from this link (Step By step CSS float tutorial[^] ) This is the best tutorial about CSS float that I even read.

I am adding rows at runtime in a gridview with a remove button in every row.
On clicking the remove button, the row having that remove button will be deleted.
Problem steps:-
1. I added 2 rows and then click a remove button of second row the second row will be deleted.
2. press f5 to refresh the page and it will give ERROR !!!
I think on clicking refresh it will fire the last event again but in this case, button that caused last event have been deleted
so button id will not found and error will be generated.
Can somebody tell me the solution !!!

Hi,
I have the directory named NDP on my local machine (named PC4) which is in a domain. On my domain server, I have IIS 6.0 (windows 2003) and database server.
I have the following sample code
<br />
protected void Button1_Click(object sender, EventArgs e)<br />
{<br />
Label1.Text = "";<br />
DataTable dt = new DataTable();<br />
<br />
<br />
StreamReader sr = new StreamReader(@"\\Pc4\C$\NDP\Test1.csv");<br />
<br />
string line;<br />
while((line = sr.ReadLine()) != null)<br />
{<br />
Label1.Text += line;<br />
<br />
<br />
}
I have impersonate="true" in web.config file. The authentication mode is WIndows Integrated authentication. I have given permissions to ASPNET accounts and Windows accounts for the NDP folder.
Can I read this .csv file? Because it is giving me error.
I have also this code.
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
String username = System.Security.Principal.WindowsIdentity.GetCurrent().Name;<br />
Label1.Text = username;<br />
<br />
<br />
}<br />
When executed it gives me the name of the user through which I have logged in but does not give access to my shared folder.
Totally stumped. Any Solutions???

It's not good idea to read the file from other machine in ASP.NET. What you should do is that you should create the web service that can copy the file from a particular machine (e.g. PC4 in your case) and upload those files to the service at specific time. then, read those files from your ASP.NET.

You will want to configure two sitemap providers in your web.config file.
Reference the MSDN article[^] on the topic - that should help you.

Well, if you normalise your data model you won't have that problem. You should only ever store a single piece of data in a column value. You should not be storing multiple tags in a single row.
You need to create a new table and split the tags out into the new table. Then set up a many-to-many join between your original table and your tags table. A many-to-many join requires the setting up of an intermediate table.

While it is possible, it is increadibly inefficient and goes against decades of guidance on how to define relational databases.

Is it possible to enter data into a grid directly when a project is run.

Yes. But GridView does not support it directly. You have to manually make it editable. Use TemplateColumns and add controls and try.

|

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:ButtonField DataTextField="DeptName" CommandName="Select" HeaderText="DepartmentName" ></asp:ButtonField>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="txt1" runat="server"> </asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void Button1_Click(object sender, EventArgs e)
{
int DeptID;
string ID;
foreach (GridViewRow gr in GridView1.Rows)
{
ID = Gdv_Dept_List.SelectedDataKey.Value.ToString();
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?

I am not sure about checking the LAN connection.

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;
}
