HTML Table Displays Random Cell Values Outside Of Table
Sep 23, 2009I am using a string builder to set up an html table row by row so that it can be emailed. 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 2 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]

SQL .net Insert Using Select AND Values?
Apr 6, 2011New to using SQL and I am having trouble accomplishing something that I figured would be simple.I am trying to create and INSERT that will insert the MAX() value from the first column in one table to the first column in another table while the rest of the columns will be filled with parameters.
I have tried switching my code around to see if I just had the syntax wrong but I've had no luck and I'm not even sure what I'm trying to do is possible (at least in a single INSERT).Here is what I have at the moment:
INSERT INTO [Table2] VALUES(SELECT(Number FROM [Table1] WHERE Max(Number)), @p1, @p2, @p3, @p4, @p5, @p6, @p7, @p8, @p9, @p10)

Select Multiple Values In DropdownList In Asp.net With VB?
Jan 20, 2012I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:
<asp:CheckBoxList ID="CheckBoxList1" runat="server" style="margin-right: 158px">
<asp:ListItem>Value 1</asp:ListItem>
<asp:ListItem>Value 2</asp:ListItem>
[code]....
but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?

View 2 RepliesSQL Injection : SELECT Fields FROM Table
Nov 17, 2011I will post a sequence of examples and thought about sql injection, I wish the expert will correct any small mistake in what I will say so I can know exactly the possible danger.
The required is to create a function in vb.net that accept 2 parameter (table_name, fields_list) and return the result in datatable
Now, I am aware of that table_name and fields_list cannot be passed as parameter to the command object using .AddParameter
here is a couple of thoughts, what I would like to know is
1- which function is exposed to sql injection
2- Which function is more safe
