View Replies View RelatedWe have two tables EmpProfile and holidaysrequest tables.
EmpProfile has fields
EmpNo
Firstname
Lastname etc
HolidayRequests has fields
EmpNo
FromDate
ToDate
holiday requests table stores the dates employees have booked as holidays.
I want to write a query which will be used by ASP page to display everyone
who have not booked 29th - 31st Dec as days off.
I have built a page that lists all our databases, the
users connected to each database, and what application
they are using. Because these databases are moved, or
removed from time to time I need to check if the database
still exists before trying to query it. Otherwise I get
funny SID errors when it tries to process this command:-
Conn4.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=CD;" & _
"User Id=username;" & _
"Password=password"
Can this be done in ASP or should I be querying the error
collection or something?
I populate a recordset and dump it into an array. How can I check if a value exist in the array? I want to check if the c_Member_mgr has a particular value or not?
Dim rs2
set rs2 = Server.CreateObject("ADODB.Recordset")
rs2.open sub_Emp_Source, Conn
Dim aSubordinates
If not rs2.EOF then
aSubordinates = rs2.GetRows()
'Close Recordset to use the new array with the 2 columns data
rs2.Close()
set rs2 = Nothing
'Declare Constants for the above SQL columns for better readability
'Use these Constants instead of referring to the array numeric indexes
Const c_Member_Mgr = 0
Const c_Subordinate = 1
Const c_EmpID = 3
Const c_EmpName = 4

View Replies View RelatedI have a web page that creates dynamical forms, depending of what kind of product it regards. When the user has chosen a product, data is collected from SQL Server and a form is created.
Some forms contains check boxes and some not. My questions is: How can I check if someone has UNCHECKED a check box? Because if that happens, I want to delete that entry from the database.
Since a form just posts the value of a check box if it is checked, this causes a dilemma.
Any ideas, I can't be the first one having this problem?

Just wondering if someone could look at this and see where I may be going wrong. The basic concept is to use FileSystemObject to see if an image exists. If it does, display the image. If not, display image does not exists message.

strFilename = ="e:path oimageprodPixscienceTN" &
(RecordSet1.Fields.Item("ID").Value) & ".jpg"
If (fs.FileExists(strFilename))=true Then %>
<%=(Recordset1.Fields.Item("ID").Value)%>
<%
Else
Response.Write("No Image Available")
End If
set fs=nothing
%>

is it possible to check a table exists before opening the record set? We have a sql query that requests information from a table depending on what information the user enters. So if the user enters information that requests a table that does not exist then I get the following error -:

I'm wanting to do a simple controlled voting page. I too our webserver off anonymous and everyone who accesses the website is a domain authenticated user. I've already done some control structure pages based on Request.ServerVariables("AUTH_USER"), which works great. That's also how I would do this page, in my basic thinking.
My idea is to have an access database with two tables. One table will have the vote written to it and the other table will have the AUTH_USER written to it when the employee casts their vote.
I'm wondering how I would do a test against that table to see if their name has already been written to the table. So, if an employee votes already, when they go to vote again, their user logon would be tested against all entries in the table and if it exists, the vote would not be written and they would be redirected to another page that politely tells them they've already voted.
I have a left menu that is accessed and displayed via XMLHTTP (it resides on the same server). Some sections of the web site don't have a "menu.asp", so a "Page Not Found" page is returned, which doesn't look great in the menu column.. Is there a way to know if a page exists before using xml.responseText to pull it?
