Evaluate Empty Value Of Ms Access, Asp, Vbscript
How we can recognize an empty value of ms access field.
Dim empVal, empVal1, num
num = 0
empVal = Recordset.Fields.Item("subj").Value
empVal1 = Recordset.Fields.Item("org").Value
here empVal = "" and empVal1 = "" i. e. in the database there are no value i.e. empty
so if i wrote
If ( (empVal = "") AND (empVal = "") ) Then
num = num + 1
response.write num
response num
end if
here value should show "1"
But it is not entering within the if condition.
So, how can we evaluate the value of empty

I'm using MSXML2.DOMDocument.4.0 to create an XML document on-the-fly.
Everything is going great except that at some point I need to create an empty XML element with a start and an end tag, not only an end tag.
Eg. I need to create <Signature></Signature> instead of <Signature />
However, MSXML2.DOMDocument.4.0 refuses to create the empty element with a start and an end tag.
It insists on creating only the closing end tag, even if I try to set text value for the element to "". Code:

I'm using an Access database connected with an ASP
website. I keep having the same problem:
Example:

do not want to show this one..
IF (qryRandom("name") = "") THEN
respone.write ("its empty!")
ELES
respone.wirte ("its filled!")
END IF
why do I keep getting 'its filled' when it is empty
any suggestions?

I have a bunch of arrays in one of my ASP scripts, and I need to construct the reference to the variable through some string contatenations. Example:
one of my variables is 'strQ1a(13)' and earlier in the script I assign a value to it. I construct the name of this variable through code like
response.write="str" & myQuestionNumber & "(" & myrs.fields("value") & ")"
- VBScript just evaluates this as a string and rather than displaying the
VALUE of variable strQ1a(13), it justs displays "strQ1a(13)"
How can I get it to look at this as a variable and get the value?

Number format :
for example,
10,500.00 ( Data type value format of standard for Ms access)
10500 ( Data type value format of general for Ms Access )
Dim val
val = recordset.fields.item("column_name").value
response.write val
In general Ms Access format, webpage is showing the expected value i.e. 10500.
But for standart Ms Access format, webpage showing the value of 10500, Instead of showing the value of 10,500.00.
If i want to show the value of standard format in webpage, then what should i do?

I've Googling the web for the past two hours trying to find some code that will explain the following:
I have a Form with 250+ fields. I need to loop through all form fields and store the values into a VBScript 2-dimensional array (name of field, value of field). Once I have this 2-d array, I need to loop through it to create my SQL insert string, which will hook up to my MS Access 2000 .mdb file.
I totally understand the process, but I'm having a hard time with the syntax. Currently, I only have 60 fields, and I'm doing this type of thing manually. The thing is the form now needs to accomodate 250+ fields and there's no way I'm continuing to do this manually. Heck no!
Can someone please help wither with syntax or links to possible examples? I've been to devguru.com, asp101.com, aspfree.com, you name it, and I simply can't find an appropriate example.

I am not sure if this is the correct place to ask this question but it is close...
IN MSAccess I can create a select statment that filters on a calculated field:
SELECT xxx, len(yyy) as zzz FROM TblAAA having (len(yyy) = 5);
I am trying to create the same type of statment in an ASP that uses VBSCRIPT to access a SQL Server table.
I can not seem to figure out what the VBScript version of the Access statmen... or even if it is possible?

I'm trying to deal with a few records in a db that are missing data in one or more fields, which breaks my page, causing a BOF or EOF error, since the recordset is empty.
I can check for an initial EOF, before any traversing of the records, but don't know how exactly to bypass execution of the record accessing from there.

i want to count all the records in my database where a certain field is empty.
heres my statement:
"SELECT Count(*) As Total FROM table WHERE field1='value' AND field2=' ' "
gives an error.
If it not possible. can the next be done:
1 count all the records.
2 count the records where field2='Yes'
3 subtract the two to get where field 2 is empty?
i know it's just something small, but i can't seem to figure it out. i also tried field2 != 'Yes'

I have a bit of code like this in a do while loop:
Response.Write "<TR><TD>Subject Name</TD>"
Response.Write "<TD>" & objRS("WRsubjectName") & "</TD></TR>"
It works fine, but sometimes the Subject Name field is empty, so instead of a blank space, I'd like to put something like "Empty Recordset" there.
Is there anyway to do this with my current code?

How the heck do you work out what is actually in a db field that appears to be empty? I have fields that appear to be empty but do not seem to evaluate to empty or null, so test using IsEmpty or IsNull are useless, I 'm guessing it contains spaces or non-printing characters of some sort but how do I test for these?

This one's probably been asked before but I'm tired of trying to find a
solution (if there is one!). I have an asp update page and I'd like to
convert all empty fields to NULL prior to updating the Access db rather than
permitting zero length fields in the db.
Is this possible? Is there any way
to globally declare this for all text fields on the asp page rather than
having to do a whole whack of "if then" formats? Is there something I can
set in the field's properties in Access that will deny zero length yet won't
cause the asp update to choke and return an error?

I have a login page where I have three different ways to authenticate a
user.
1. Use integrated authentication and read the server variable AUTH_USER and
then verify if this is a valid user from a database. If OK I write some
session cookies and then re-direct to another page placed in the same folder
(which will read the cookie and verify that it is valid). This works OK.
2. Use anonymous login where the user is typing in a username/password which
is checked against a database and if OK I write session cookies and then
re-direct to other page which reads this cookie. This also work OK.
3. Now we read another server variable that is set by a third party oracle
product (don't know much about this product but when I print the value of
the servervariable it is OK). I write some cookies and then redirect to
another page. When I read the cookie now it is empty. If I read the cookie
just before I do my re-direct it is OK but after the re-direct it is empty.
Do you have any sugestion why the cookie becomes emtpy after the re-direct
in the third case but not in the other two? It is the same code doing the
actual reading/writing of the cookies in all three options above.

I have a table in MS Access that's used for users to post announcements on. There's only one problem- if it's empty (meaning there are no announcements), the page returns an error stating that either BOF or EOF is true. Basically, it doesn't like the null status of the table. Is there a way to state something like 'There is nothing currently here.'? I've been playing with this code but it hasn't worked yet:
If an.EOF=an.BOF Then
Response.Write("There are currently no system announcements.")
Else
do while not an.eof
'This starts a loop that lists them all
End If
