 I'm making the leap to move from vb.net to C#, and I'm getting this crazy error when I try to execute one sp, set a value, and then execute another sp based on the value.   Any suggestions??? proc_GetSectionDetails is my first stored procedure.  From that, I get a value for SectionID, and then use it for the second sp called  proc_GetSectionDetails protected void getSectionContent() { SqlConnection conn = default(SqlConnection); SqlCommand comm = default(SqlCommand); SqlDataReader reader = default(SqlDataReader); string connectionString = ConfigurationManager.ConnectionStrings["123"].ConnectionString; conn = new SqlConnection(connectionString); comm = new SqlCommand(); comm.Connection = conn; comm.CommandType = System.Data.CommandType.StoredProcedure; comm.CommandText = "proc_GetSectionDetails"; comm.Parameters.AddWithValue("SubSectionID", Request.QueryString["SubSectionID"]); conn.Open(); reader = comm.ExecuteReader(); if (reader.Read()) { lblName.Text = Convert.ToString(reader["SubSectionName"]); lblDesc.Text = Convert.ToString(reader["SubSectionDescription"]); Label SubSectionParentID = new Label();

get the handle of System.Web.UI.WebControls.TextBox

  

Hello,

I am trying to make a textbox re-size to fit the text provided. I found a solution in C#:

Graphics g = Graphics.FromHwnd(textBox1.Handle);
SizeF f = g.MeasureString("String to fit", textBox1.Font);
textBox1.Width = (int)(f.Width);
// textBox1.Height = (int)(f.Height); // if required...
textBox1.Text = "String to fit";

I'm using VB.net and the Textbox1.handle is not present in VB.net. The project is running on .NET Framework 1.1

Is there another way to get the handle of the TextBox?


Thanks in advance!

Regards,

Heisa

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm

  

Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 


I already have read rights to IIS user to my BIN folder. 


Thanks for the help.

Hi,

This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
        {
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        }


Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

 

On web.config I already have this:
<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

Thanks.

Types in Yukon: Managed UDTs Let You Extend the SQL Server Type System

  

The next version of SQL Server, code-named "Yukon," will offer enhanced support for user-defined types (UDTs). Because UDTs can be managed by the CLR, you can represent a wide variety of data structures to create types not possible with previous versions of SQL Server. With UDTs you can more precisely control the kind of data your type accepts, resulting in better data management. This article explores UDTs in "Yukon" and covers their design and implementation.

user control derived from System.Web.UI.WebControls.WebParts only fires its OnPreRender and CreateCh

  

 I have a application which uses webparts.

So my user controls are derived from System.Web.UI.WebControls.WebParts which makes them webparts.

I have everything setup and working fine as far as the personalization and webpart goes... every thing displays and works fine.

Except that 1 of my control needs to do a bit of work in the OnPreRender event and it turns out that event only gets fired when a user is loged in the application.

So lets imagine that an administrator while logged in switched to 'Sharedscope' within the webpartmanager and then has added the usercontrol/webpart 'calendar' to the top webpart zone. This then makes the 'calendar' control viewable by all and any user who visits the page wheter logged in or anonymous.

And this works fine and very well as it is supposed to. However in the 'Calendar' user control which is derived from System.Web.UI.WebControls.WebParts I have an overiden 'OnPreRender' event like this:

Protected Overrides Sub OnPreRender(ByVal e As EventArgs)

If Not Me.DesignMode Then

Me.isloaded = True

' Test for ScriptManager and register if it exists

sm = ScriptManager.GetCurrent(Page)

If sm Is Nothing Then _

Throw New HttpException("A ScriptManager control must exist on the current page.")

I've read a bit about this error and maybe I have nothing to worry about.  BUT ... my simple little app gets 7 of these before it even gets to the first Dim statement in the Class Form1!  I found and followed instructions on how to have the Debugger intercept these exceptions but it seems that they are not being intercepted.  I only know that they have happened because of the messages in the Immediate Window.  In the Designer all I have is 5 Labels and 5 TextBoxes.   Any thoughts on how I could get to the cause of these messages?
