Add Fieldnames to a Listbox/Combo

[Tanny]

Project : A Query Web Client
Problem1: How can I add the fieldnames of a
table directly into a listbox/combo control on a webpage
Problem2: A field within the table say has 5 possible values as of now. I want a combobox to
be populated with these values without me entering them manually or assigning them to the combo box as selection or option.
Example
fieldname status contains values such as complete, incomplete, deferred, reported, needs verification.
Assume if their are 4000 records in the table the status field would carry a value which is one of these.
I want the combo to get populated against a command button captioned "possible values" which, when hit by the user the combo has the possible values added. I hope whoever reads this understood what I am hinting at. Otherwise please get back to me so that

Thank You for your time in reading and understanding my problems.

I have the exact same problem as you (problem 1).

I'd really like to know the answer as well.

One of the Recordset object's properties is a collection named Fields.

Here is a sample:


Dim Rs as Recordset
Dim i as Integer

for i = 0 to Rs.Fields.Count - 1
MyList.AddItem Rs.Fields(i).Name
next

If you are running an activex control that you built for use on the web, then you can use a standard combo box, but if you want VB to return some HTML to the client, you'll have to use the option and select tags to build that list. You can do it with something like this:

you will have to figure out the best place for this code - whether an ASP page or inside a custom dll, etc.

You can use this code to get all the field names into a dropdown box on the web page. Then when they choose one and click the "possible values" (which in HTML terms would an input type=submit) that will post this information to another page that will use the second chunk of code below to generate the list of possible values.


dim str as string
dim i as integer
dim rs as recordset

'get an empty recordset
'SELECT * FROM Table WHERE 1=2
'open the recorset
...
str = "<select name=fieldname>" & vbcrlf
for i = to rs.fields.count - 1
'build the html stream to build the drop down box
str = str & "<option>" & rs.fields(i).name & "</option>"
next x
str = str & "</select>"

'send this html to the client
response.write str




Here is the code to fill the drop down box with the values in the field that the user selects, the field name would be passed to this page in the form collection from the previous code.


dim rs as recordset
dim str as string
dim sql as string

'open the recorset with the distinct values from that field that was chosen.
'ie
sql = "select distinct " & request.form("fieldname") & " from table "
...

'build the list...

str = "<select>" & vbcrlf
While Not rs.EOF
'i included some code formatting so if you wanted to do a view source on the resulting html page it would be readable the vbcrlf's and vtTab's
str = str & "<option>" & rs!fieldname & "</option>" & vbcrlf & vbtab
rs.movenext
Wend
str = str & "</select>"

response.write str




Hope this helps and makes a little sense,
John
