Hi, I have read an article by Kelum Ganegoda on reading blobs. In his article he showed how to display images that were stored in blobs using the ExecuteScalar() method of the SqlCommand class which returns an object. So we cast it and store in a byte array like this.
byte[] _buf = (byte[]) _cmd.ExecuteScalar();
Then, stream it back to the HTTP response. The problem is that his article shows how to display images not text files. I'd like to display text files in the same format as the original files prior to being sent to the database. How would I go about doing that? Thank you in advance for your help.

Exactly the same way, except that you use a different content type.

What about the format of the file, how do I get the format of the displayed file to be the same as the original file? Thanks

Hello!
I have this sql statement below:
Dim strSQL As String = "SELECT EmailAdd from vwDepList where Member_ID =' " & dropAssigned.SelectedValue & "'"
I want that my lblEmailAdd.text will refelect the value of strSQL depending on the dropAssigned.SelectedValue.
Need a tutorial. Thanks.

I am C# guy so I will write in C#. You can translate it into VB.NET
lblEmailAdd.text = GetEmail(dropAssigned.SelectedValue)
private String GetEmail(String memberID)
{
SqlCommand command = _Connection.CreateCommand();
String SQL = String.Format("SELECT EmailAdd from vwDepList where Member_ID
= '{}'",memberID );
command.CommandText = SQL;
command.CommandType = CommandType.Text;
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = command;
DataTable table = new DataTable()
adapter.Fill(table);
string email = (string)table.Rows[0];
return email.
}
Above _Connection is the SqlConnection to database.
Hope that helps.

Do you want to run this object on the server, or the client ? If the server, why ? If the client, it has nothing to do with ASP.NET, you need to do it using javascript, if that's possible. It doesn't seem likely to me.

Hi,
When you add grid view, to bind it to datasource, the best practice is below:
Click on the property builder (the little black arrow comes up when you click on GridView):
-->Add New Column:
-->Choose field type = bound Field
-->HeaderText = your choice
-->DataField = "The name of the column in your datatable.
Now go to GridView property:
AutogenerateColumns = False
Doing the above you won't have to hide any columns, you will see what you have decided. If you are worrying about the primary key, set that in the "DataKeysNames":
DaatKeysnames = (ColumnName from your DataTable) "PrimaryKeyColumnName"
Hope that will solve your problem.
Cheers.

I don't think it's possible, unless you're somehow able to work out their timezone ( using geoip ) and work out the time from there ( which may not be the time their PC is showing ). This is why most web sites ask you what timezone you are in, because they can't work it out for themselves.

Use Javascript to get the client time:
vad d = new Date();

I have an aspx page in a project that was recently converted from VS 2003 to VS 2005. The page contains a UserControl which is located w/in the same application. Here's the file structure:
/includes/parent1/parent2/EditProfile.aspx
/includes/utils/StateDropDown.ascx
And I am getting the following error message from the VS compiler (not from the web because I can't compile the site): The virtual path '/includes/utils/StateDropDown.ascx' maps to another application, which is not allowed.
The project is file based, not http or ftp and there are no virtual directories in the project, so all directories w/in the project are in the same application. Why am I getting this error, and how can I fix it? Please help!
I've looked all over the web and all the related topics seem to relate to dynamically loading UserControls. The UserControl in question is added to the ASPX page using:
<br />
<%@ Register TagPrefix="uc1" TagName="StateDropDown" Src="/includes/utils/StateDropDown.ascs" %><br />
Thanks,
Mark

Put a ~ at the front of the path, this maps to your application root. Or, use a relative path.

I have a GetData methd which is returning a table using sqldataadapter. I bound that datasource with GridView but now I want to invisible Gridview's first column but it gives me following error although I have 5 columns in my datatable.
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
GridView1.DataSource = GetData();
GridView1.DataBind();
GridView1.Columns[1].Visible = false;
Thanks for help me in advance

You must have called the code for making it "visible=false" before the gridview being bound to the datasource
put if(gridview1.rows.coun>0)
{
control.visible=false;
}
It should work.

What's wrong in the following statement.
if ((Convert.ToInt32(e.Row.Cells[2].Text)>=15))&& (Convert.ToInt32(e.Row.Cells[2].Text)>=17))

seemamltn wrote: ((Convert.ToInt32(e.Row.Cells[2].Text)>=15))&&
You have an extra bracket, it is suppose to be if ((Convert.ToInt32(e.Row.Cells[2].Text) >= 15) && (Convert.ToInt32(e.Row.Cells[2].Text) >= 17))
|
|
|
|
|
The syntax error comes from mismatching parentheses.
What's really wrong about the statement, is that if the value is >= 17, then it always is >= 15, so half of the code is totally superfluos.
if (Convert.ToInt32(e.Row.Cells[2].Text) >= 17)

TimeSpan ts = DateTime.Now.Subtract(DateTime.Parse("6/20/2007 11:21 AM"));
string strTimeDiff = ts.TotalHours.ToString();

I have a web form which has some radiobuttons in it. it looks like this:
asp:RadioButton ID="RadioButton1" runat="server" AutoPostBack="True" Checked="True" GroupName="aa" Text="r1"
asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="True" GroupName="aa" Text="r2"
asp:RadioButton ID="RadioButton3" runat="server" AutoPostBack="True" GroupName="aa" Text="r3"
asp:Label ID="Label1" runat="server"
in the vb file,
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Me.RadioButton1.Checked Then
Me.Label1.Text = "r1 is selected"
ElseIf Me.RadioButton2.Checked Then
Me.Label1.Text = "r2 is selected"
ElseIf Me.RadioButton3.Checked Then
Me.Label1.Text = "r3 is selected"
End If
End Sub
when the page is loaded, r1 is selected, then I click r2 and r3, then click BACK button in Internet explorer, the label text changed correctly, but not radiobutton selection. Can anybody explain it? and is there anyway to fix this?
thanks,
