HTML Table Displays Random Cell Values Outside Of Table

I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.

View 8 RepliesTake Values From One Table, Based Off The Values In Another?
Apr 9, 2012[code]If I wanted to get Part Name for multiple PartIDs from OrderDetails, how would I go about doing this? Would I use two DataTables? I'm confused as I cannot see an efficient way to do this. The only thing that I can think of is to create a DataTable with SQL:[code]and then maybe use a For loop to take each PartID, create another DataTable to find the PartName for that and then give this to a variable. There could be up to 10 PartIDs to search through and I don't want to have variables such as PartID1 PartID2 etc. [code]

View 1 RepliesRestricting An Interface To Structures Only?
Aug 4, 2011I have an interface IDigitalState defined as
Public Interface IDigitalState
ReadOnly Property Code As Integer
ReadOnly Property Name As String
End Interface
[Code]....
What I wanted to do was declare a variable as a nullable type of IDigitalState. I understand why I cant do this because the interface may be implemented by a class which is not allowed to be nullable. Is there a way to define the interface so that it can only be implemented by a structure.

Dec 8, 2009I have developed a Windows Forms application using VB.NET and MS SQL Server 2005 Express Edition. My database name is 'AC'. I do not want ANY user, SQL Server or Windows authenticated, to access, read, write to, update, drop or take backups of this database, except this login 'Adel'. So my connection string looks very similar to:[code]What configurations should I make in the MS SQL Server Management Studio 2005 Express Edition to 'Adel' login, 'AC' database, and all other logins to accomplish this?Given the following:I do not own the server; my client owns the server.

How To Compare Values From Same Table
Jun 8, 2011I need comparing value from the same table for my final project.
Example :
Table 1 :
SubjectCodeClasses
Sub Aclass 1
Sub Aclass 2
Sub Aclass 3
Sub Bclass 2
Sub Bclass 3
Sub Bclass 4
Sub Bclass 5
Sub Cclass 6
Sub Cclass 7
Sub Cclass 8
...
My task is, I need to compare the classes in the subject. Sub A with class 1, class 2, class 3 have to compare with Sub B and Sub C. if classes from Sub A exist in Sub B then the output is 0, if not the output is 1. then Sub A again will compare with Sub C and the rest. After Sub A compare its value with other subject. Sub B will start comparing with all the subject and so on.
Below is the concept.
Sub ASub BSub C
Sub A001
Sub B000
Sub C100
I really don't know to do the loop..
