Using ADOX To Delete A Column

Here is the code I'm trying (but it errors out with "Item cannot be found in the collection corresponding to the requested name or ordinal."):

objTable.Columns(s_name_field_to_delete).delete
AND SAME ERROR WITH:
objTable.Columns.delete s_name_field_to_delete
AND SAME ERROR WITH:
set objColumn = objTable.Columns(s_name_field_to_delete)
objTable.Columns.delete objColumn

What am I doing wrong?

cat.activeConnection = conn

With tbl
.Name = "events"
Set .ParentCatalog = cat

ADOX Code, Books, Online Reference

I want to learn to manage my Access database schema (add tables, drop tables, add columns, etc.) remotely by accessing it through ADOX. Microsoft's online documentation is OK, but the code samples are buggy and they're in VB, not VBScript.

Can anyone point me to:

A) ADOX documentation on the Web that's better than Microsoft's

B) Downloadable code that uses ADOX for schema maintenance.

C) A good book on ADOX programming.

Get Column Name And Value Of Specific Row

Ok let me explain what I am trying to do as easily as I can. I have a table in my access database that I am connecting to. I select a specific id number using my SQL statement. Now what I am trying to do is scroll through that records row and get the column name of that column along with the value of that cell. I hope that isn't to confusing.

Column Descriptions

How do you get the description of fields in an Access database? I really need this and can't find it anywhere....
It would also help if someone showed me how to get the datatype and other info (like if it's a Yes/no or True/False field).
What is the resource/doc for this so I know where to look before asking from now on?

How Do I Call The Last ID In A Column

Ok i'm self taught with regards to ASP so not great etc, so sorry if this is a really basic question..

On the last line here i'm trying to some how get it to call the last ID entry...

ImageID = Request("ID")
If (Len(ImageID) = 0) then ImageID = "1"
If Not IsNumeric(ImageID) Then ImageID = "1"
If ImageID = "0" then ImageID = "1"
If ImageID>3 then ImageID = max(Len(ImageID))

This is basically for some max min links for a online comic here's what it links to

<a href="default.asp?id=<%=ImageID-1%>">< Backwards</a> -
<a href="default.asp?id=<%=ImageID+1%>">Forward ></a> -

Changing Column

I need to set up an HTML table or the like, with 4 columns.
Each column needs to have a header with a FRIDAY (dd/mm/yy) date.
i.e. this weeks Fridays date is 16th Feb, the following is 23rd Feb
etc.
So, I need column 1 to be headed 16th Feb, col 2 to show 23rd Feb etc.
As this week passes, the dates need to move up 1 week, so that next
week, col 1 will display 23rd Feb and so on.
These headers need to change according to the date.
Please can you advise how I best achieve this ?

Freeze Column

we have a requirement to freeze the column and row column heading... so that when the user scrolls to the right the first two columns ( I refer them as "row headings") will stay and the remaining columns scroll left and when the user scrolls to the bottom the first row stays ("column headings")and the remaining rows will scroll up.. This can be easily accomplished in EXCEL by freezing the itersecting cell... How can the same be accomplished using HTML tables /ASP code.... Is there any Active X control available that can be used to accomplish the same?Our technical env is ASP and Oracle DB

ORDER BY A Column?

If I have several fields:
a | b | c | d | e

and the original SQL = SQL & " ORDER BY a ASC ".

I want to place links to b, c, d, e to make the table of results to show by ascending order of b (or , c, d, e).

do I need to place an "if/ end if" in the sql or do I put some statement in the paging?

example
a (ORDER BY a ASC)| b | c | d | e
1 | 3 | z
2 | 2 | y
3 | 1 | x
4 | 5 | w
5 | 4 | v

to

a | b (ORDER BY b ASC)| c | d | e
3 | 1 | x
2 | 2 | y
1 | 3 | z
5 | 4 | v
4 | 5 | w

SmallDateTime Column

I have an asp page which the user enters a time(e.g. 12:21). I need to insert this time into a SQL Server DB, which has a smalldatetime column.

I am trying to process the insert through ado, eg:

objRS.AddNew
objRS("Field1") = strText
objRS("DateField") = dteValue
objRS.Update

3 Or 4 Column Display

Is there a way to have a piece of repeating information display in multiple columns like a phone book? I need to display a list of contract numbers which will link to the actual contract.

There is no other information to display and it would be better if I could display 3 or 4 columns on the page like a phone book. Hope that makes sense. I am using Dreamweaver and it's and Access db if that helps.
