Hi,
I have an xml file with employee data and need to uplaod its content to the database.
For this I have used dataset.ReadXml method and then I am using the dataadapter.update method to upload the content of the dataset to the database.
Here is the code:
protected void Button1_Click(object sender, EventArgs e)
{
string path = @"D\emp.xml";
string dsTable = "";
string connectionString = @"Server = DB\SQL2; Database = CWBDB; user = sa; password = sa";
DataSet ds = new DataSet("EMPDS");
ds.ReadXml(path);
foreach (DataTable t in ds.Tables)
{
dsTable = t.ToString();
}
SqlConnection con = new SqlConnection(connectionString);
SqlDataAdapter da = new SqlDataAdapter();
da.TableMappings.Add("EMP", dsTable);
if ((da.Update(ds))>0)
{
Label1.Text = "Uploaded the data successfully";
}
else
{
Label1.Text = "Could not Upload the data";
}
}
But I see an exception:
"Update unable to find TableMapping['Table'] or DataTable 'Table'."
Please help!

da.TableMappings.Add("EMP", dsTable);
The above statement of my code makes a mapping between database table and dataset table, the first parameter is the database table name and the 2nd paramaeter is dataset table name. So I am getting the table name from the dataset and passing to it so that a mapping may occur between the database table and the dataset table.
In short I will explain what I am trying to do. Theres an xml file consisting of Employee data, I need to upload this xml content to the Database. For this I have used the Dataset.fill(xmlpath) and then using the dataadapter for updating the data to the database. Now u can see my previous code and get clear understanding.

Hi All,
What is meant by pearreview and codereview?
Explain me with example
Thanks.

Hi,
PeerReview is review done by your peers (co-workers)to identify bad code which leads to malfunctioning of the application.
CodeReview is also the same thing but can be done by anyone not only your peers.

Hi all,

This is because you can`t execute the project if you do so. You have to do vice versa. can any buddy gimme the command or an exe file that should be executed to solve the prob.
thanks in adv...

Hello,
VS 2005
I have created a web service and the web service as a connection string in the config file.
Only the user will know the connection string details when they first install the web service. i.e. server, user id, database etc.
I have created the setup using the msi webSetup.
However, my problem is how do i get the user information for the connection string from the user and update the web.config with the new connection details.
Need serious help with this, and code examples would be most helpful.
Thanks very much,
Steve

Hi,
I am trying to create a web control that contains a hyperlink and an image and make it possible to set some properties.And I want to show a popup when the mouse is over one of them.From what i understand a solution would be to include the image in the hyperlink and write the code for the necessary events only for the hyperlink.But when I include the image in the hyperlink, and a literal to I no longer see the image.Do you think you can help me with that?
Thanks
Here is how I try to include the image:
hyperlink.Controls.Add(image);<br />
hyperlink.Controls.Add(literal);<br />
this.Controls.Add(hyperlink);
I want the page source to look something like this
<br />
a href="http://www.zzz.com" style="font-size:10px"><br />
<img src="http://www.zzz.com/295384c2bbdd7a96e5432be08b42036e.gif" width="50" height="50" <br />

Why not use a linkbutton
something like
<br />
asp:LinkButton id="lbtnJumptToZZZ" runat="server"><br />
<img border="0" src="http://www.zzz.com/295384c2bbdd7a96e5432be08b42036e.gif" alt="ZZZ"><br />
asp:LinkButton<br />
the click event should then contain the redirect to the page or opening it
in a new window.
//To open in a new window:
<br />
private void lbtnJumptToZZZ_Click(object sender, System.EventArgs e)<br />
{<br />
string webRef = "http://www.zzz.com";<br />
<br />
script = "<Script Language=\"JavaScript\"> " + <br />
" window.open " +<br />
" ('" + webRef + "','','scrollbars=yes,menubar=no,height=600,width=800,resizable=yes,toolbar=no,location=no,status=no'); " + <br />
"</Script>";<br />
<br />
Page.RegisterStartupScript("script", script); <br />
}<br />

That's not what i want  .I want to know how to include ,using c#, an image in a hyperlink(linkbutton() so that when i click on the image or on the text redirects me.

If you want to this at the code behind:
<br />
LinkButton lbtn = new LinkButton();<br />
lbtn.Click += new System.EventHandler(this.lbtn_Click);<br />
<br />
lbtn.Text = "The text to display " + "<img border=\"0\" src=\"http://www.zzz.com/295384c2bbdd7a96e5432be08b42036e.gif\" alt=\"ZZZ\">";<br />
<br />
this.Controls.Add(lbtn);<br />
<br />
<br />
private void lbtn_Click(object sender, System.EventArgs e)<br />
{<br />
Page.Redirct("http://www.zzz.com/"); <br />
}<br />
It's not easy to make the text and the image align the way one wants, so
often I splitt it in to 2 linkbuttons. One for the name and one for the image.

Hers a custom control you can use:
<br />
using System;<br />
using System.Web.UI.WebControls;<br />
<br />
namespace My.Controls{<br />
<br />
public class TruncLabel :Label {<br />
public TruncLabel() : base (){}<br />
<br />
protected override void Render(System.Web.UI.HtmlTextWriter writer){<br />
this.CssClass="fxS";<br />
this.ToolTip = this.Text;<br />
base.Render(writer);<br />
}<br />
}<br />
}<br />
Your stylesheet should then contain the following:
<br />
.fxS<br />
{<br />
overflow:hidden;<br />
white-space:nowrap;<br />
overflow-clip:rect(auto, auto, auto, auto);<br />
}<br />
The page containing the datagrid
<br />
<%@ Register TagPrefix="mi" Namespace="My.Controls" Assembly="MyProjectOrSomething" %><br />
.<br />
.<br />
asp:datagrid id="myDataGrid" runat="server" CssClass="grid" GridLines="None" AutoGenerateColumns="False"><br />
Columns><br />
asp:TemplateColumn HeaderText="Name" ItemStyle-VerticalAlign="Top"><br />
ItemTemplate><br />
mi:TruncLabel id="tlblName" Font-Bold="True" runat="server"><br />
<%#DataBinder.Eval(Container.DataItem, "strCompanyName").ToString()%><br />
mi:TruncLabel><br />
ItemTemplate><br />
asp:TemplateColumn><br />
Columns><br />

}
try to replace with this ddlstCategoryList.Items.Add(new ListItem("text","value");
you have to use another overrided method (with parameter is ListItem object)
