Accessing control in a listview from code behind

In this case we are accessing the hyperlink control from the code behind to format the NavigateURL property of the control

 Protected Sub lvTACRlist_ItemDataBound(ByVal sender As Object, ByVal e As  System.Web.UI.WebControls.ListViewItemEventArgs) Handles lvTACRlist.ItemDataBound

        Dim h1 As HyperLink = CType(e.Item.FindControl("hyperLink1"), HyperLink)
        h1.NavigateUrl = h1.NavigateUrl + "&H=" + ddhoslist.SelectedValue.ToString()

 End Sub

Accessing control in a gridview from code behind

Protected Sub GridView1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.PreRender

For Each gvRow In GridView1.Rows
 If gvRow.RowType = DataControlRowType.DataRow Then
   Dim h1 As HyperLink = CType(gvRow.Cells(0).Controls(0), HyperLink)
   h1.NavigateUrl = h1.NavigateUrl & "&H=" & Request.QueryString("H")
 End If
Next

End Sub

Accessing masterpage objects from child page

I had a project where I had to pass in the hospital code to the link button that was at the top of the each page . The top section of the each page was a masterpage.

I added a property called SetHospitalCode on the masterpage as follows

Public m_HosCode As String
    Public Property SetHospitalCode() As String
        Get
            Return m_HosCode
        End Get

        Set(ByVal value As String)
            m_HosCode = value
        End Set

    End Property

--------
Protected Sub DashBoard_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles DashBoard.Click
      
   If m_HosCode Is Nothing Then
            Response.Redirect("DashBoard.aspx")
    Else
           Response.Redirect("DashBoard.aspx?H=" + m_HosCode.ToString())
   End If
End Sub

I set the property from the each child page as follows
Dim getMaster As MasterPage
 getMaster.SetHospitalCode =  hospitalcode 

where hospitalcode is the new value of the hospital from each page.
DashBoard is the ID of the linkbutton

error:process could not execute 'sp_replcmds' error on Publisher with Remote Distributor

Today the replication failed on our Publisher. We have a transactional replication running from Publisher to the  Subscriber and they  are in two differnt machines, both using  SQL 2008 R2. The exact error we got was

1. Replication failed: process could not execute 'sp_replcmds' error on Publisher with Remote Distributor
2. The database owner SID recorded in the master database differs from the database owner SID recorded in database 'databasename'

Tried  the following step with success.

 --STEP 1

exec sp_changedbowner [domain\user]

This made the [domain\user]  account the owner and mapped it to dbo 

--STEP 2

In SSMS find the replication and expand it
Expand the local publication folder
Select the publication and right click on it and seclet "View Log Reader Agent Status"
Stop the Agent and Restart the agent


Now all ther replications were back in sync.

I ran the follwoing query to see if they are back up running

select * from distribution..MSrepl_transactions order by entry_time
