Why this code line doenst work?

Hello,

I have the following code in the Global.asax:

Sub Session_Start(Sender As Object, E As EventArgs)
Thread.CurrentThread.CurrentCulture = New CultureInfo("en-US")
End Sub

The Error I get: "Name 'Thread' is not declared."

However when I have this in my aspx code it works:

Sub Page_Load(Sender As Object, E As EventArgs)
Thread.CurrentThread.CurrentCulture = New CultureInfo("pt-PT")
End Sub

Why?
Can't I set the culture in the Global.asax?

Thank You,
MiguelHi, Shapper.

Did you Import the System.Threading class? Or use the full name,
System.Threading.Thread.

My first guess would be that you are missing the namespace of this "Thread"
class or use the complete namespace reference while using "Thread"

Thread class is in System.Threading

Ah,

I just found out. I forgot the dam line in Global.asax:
<%@. import Namespace="System.Threading" %
I had it on my ASPX page. I didn't even notice.

Sorry for the time.

Thanks,
Miguel

Why this error when table has this column name

I know my table has this column but I keep getting the following error doesn't make sense: (my code for the for the button is below the error)

Column 'CompanyID' does not belong to table Categories.

I found my answer -- I wasn't calling these columns in my stored procedure--I had the wrong stored procedure in my dataadapter

Why this error message?

VB.NET / ASP.NET

I have a simple test. One simple Formview connected to a datasource. I
have Button1 outside of the Formview. The Formview starts in ReadOnlyMode.
All I want to do is on the button click, change the formview to Insert mode
and then put the current date in the date textbox. The date textbox ID is
DateTextBox and I've double check that to make sure it's right. Here's my
simple code.

Protected Sub Button1_Click1(ByVal sender As Object, ByVal e As
System.EventArgs)

FormView1.ChangeMode(FormViewMode.Insert)

Dim datetb As TextBox = FormView1.FindControl("DateTextBox")

datetb.Text = Now.Date.ToShortDateString()

End Sub

This is the error message I'm getting.

Object reference not set to an instance of an object.

Hi Phil

Are there any entry in the datasource?
Yes, there are entries in the Datasource. If I manually put the date in, it
works perfectly. I just want when the user clicks this button for the
formview to auto switch to Insert mode and auto put in today's date for them
in the datetb.
Thanks!
Phil

i new to asp.net, i have use the following code to bind the database to datagrid control.

<%@dotnet.itags.org. Page Language="VB" %>
<%@dotnet.itags.org. import Namespace="System.Data" %>
<%@dotnet.itags.org. import Namespace="System.Data.SqlClient" %>
<script runat="server"
' Insert page code here
'
Sub Page_Load(Sender As Object, E As EventArgs)
Dim DS As DataSet
Dim MyConnection As SqlConnection = New SqlConnection("server='(local)'; trusted_connection=true; database='model'")
Dim MyCommand As SqlCommand = New SqlCommand("SELECT * FROM jobs", myConnection)

DS = new DataSet()
MyCommand.Fill(ds, "jobs")

DataGrid1.DataSource=ds.Tables("jobs").DefaultView
DataGrid1.DataBind()
End Sub
End Sub
</script>
<html>

why this doesnt work?

<%@dotnet.itags.org. Page Language="C#" %
<span id="span1" runat="server">Test_String</span>
<br><br
<%
Response.Write (span1.ID); // works: span1
Response.Write ("<br>");
Response.Write (span1.InnerHtml); // works: Test_String
Response.Write ("<br>");

Response.Write (FindControl("span1").ID); // works: span1
Response.Write ("<br>");
Response.Write (FindControl("span1").InnerHtml); // doesn't work, why??
Response.Write ("<br>");
%Hi,

FindControl returns back something of type control so you have to cast it first to the correct type.

Grz, Kris.
thx XIII
but how? any hint?
Change:

 Response.Write (FindControl("span1").InnerHtml);

to:

 Response.Write (((HtmlGenericControl)FindControl("span1")).InnerHtml);

To make this a bit less cryptic, here's how it works.

First, we use FindControl to actually grab the control:

FindControl("span")

However, this will give us a Control. As your error states, Control does not have an InnerHtml property. So, we first cast from a Control to a HtmlGenericControl (which is what the <span> is):

(HtmlGenericControl)FindControl("span")

Now, we put brackets around this combination, to give us our resulting HtmlGenericControl object:

((HtmlGenericControl)FindControl("span"))

Now that we have an HtmlGenericControl object, we can specify its InnerHtml property:

((HtmlGenericControl)FindControl("span1")).InnerHtml

I hope this helps.
hi, SomeNewKid,

thanks for yr help.
I tried yr way, but still not work :(
can you run this program ok in your machine?
> can you run this program ok in your machine?

Yes. With that single line change, your sample runs fine. Remember that C# is case-sensitive ... so you must type it exactly as shown.

When you say it still doesn't work, what exactly do you mean?

Do you get an error? If so, what does the error say?

Do you get an output that you did not expect? If so, what output were you expecting?
thanks to SomeNewKid, I got it! it runs ok now.

here is another probem, I added two 'Reponse' lines, first & second run ok, but the third line got a error. Is this 'HtmlGenericControl' not for a 'TD' tag?

<%@. Page Language="C#" %
<span id="id_span" runat="server">span_string</span>
<div id="id_div" runat="server">div_string</div
<form id="form1" runat="server">
<table id="table1" border="1" runat="server">
<tr id="id_tr" runat="server">
<td id="id_td" runat="server">td_string</td>
</tr>
</table>
</form
<%
Response.Write (((HtmlGenericControl)FindControl("id_span")).InnerHtml); // ok
Response.Write (((HtmlGenericControl)FindControl("id_div")).InnerHtml); //ok
Response.Write (((HtmlGenericControl)FindControl("id_td")).InnerHtml); // got error!
%>

> Is this 'HtmlGenericControl' not for a 'TD' tag?

Correct.

Here's a loose description of why:

The HtmlGenericControl is used for any control that is not "special" to ASP.NET.

A <span> tag is nothing special. It is just a tag sitting by itself, with no required parent or child tags. So, it's just a HtmlGenericControl.

A <td> tag, on the other hand, is not a tag sitting by itself. It must have a parent <tr> tag, and a grandparent <table> tag. This required structure makes tables "special" to ASP.NET. So, a <table> is an HtmlTable control, a <tr> is an HtmlTableRow control, and a <td> is a HtmlTableCell control.

Hence, you can get your code working by changing:

 Response.Write (((HtmlGenericControl)FindControl("id_td")).InnerHtml);

to:

 Response.Write (((HtmlTableCell)FindControl("id_td")).InnerHtml);

So, how on earth can you know which tags are generic, and which are special?

As always, the answer is in the documentation:
System.Web.UI.HtmlControls Namespace
oh, SomeNewKid! You are a good teacher! I love you so mucn~~~~
I think now I understood a lot about it, thank you very much!

p.s.
and I found 'HtmlContainerControl' can get work too :)
You're welcome.
