I'm terribly sorry if this has been asked before, but I need a clear explenation without having to sift through other bits of information.
Can somone explain how functions work in asp (not asp.net)? I need to call a function that returns a value, and I get an error when I have a return statement in there. If there is no "return" statement, then what do you use to get this value back?
..:: The Specs:
MS Access 2000 (host charges extra for SQL/MySQL)
MS Windows Server 2003 (prod) / MS XP SP1 (dev)
..:: The setup:
The database has been setup with two tables;
tblDownloads
tblCatagories
Each "download" consists of a catagory field that corresponds to fldID in
tblCatagories. Each catagory, where the catagory is a parent, has a parent
field of value: 0 and each child, has a field with a value corresponding to
the fldID of it's parent. Code:
I have implemented a logic for my requirement with a recursive call. The logic is I need to get IDs from database for a scenario. There are corresponding records for each ID.
I need to store these IDs in an array variable. Then I need to get (dependent)IDs for the fields in each ID. There may be morethan one dependent per each ID. I append these IDs to my array. Like this it goes.
The problem is if there are many levels like this, the number of database cursor count is reaching to maximum and I'm getting the error
{Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC driver for Oracle][Oracle]ORA-00604: error occurred at recursive SQL level 1 ORA-01000: maximum open cursors exceeded }
each recursive call runs a SELECT query.
Can any one suggest me an alternate solution for this ?
I am using WindowsXP and a book to try to learn ASP.
The book instructed me to install IIS & .Net Framework v1.1 (which I did)
In the book they gave me the following code:
I'm very interested in finding out what ways you experts out there have made your data dips more efficient in your asp (not asp.net) code.
I have a wizard-type application that dips into the database with each page, I know there's a better way to do this out there, just pressed for time and can't think right now.
I need to implement an application that receives http calls from a remote
client, do something with it and returns some feedback. I want to use IIS
(version 6) as my front end http server (with https and ssl services) which
will facilitate all the requirements of a http server and then foreword the
incoming call to my application and will return the process result to the
client at the end.
Does IIS support this? And if yes - what are the requirement from my application to use it (built in .net if anyone interested)?
Is there a way I can see how many database calls were made from my script to the db server to check how well my SQL queries are formed?
I get the time taken to execute the queries, but in that time taken, I want to know how many calls were made to the DB server. Is it possible?
I'm developing web surveys where users logon to a web survey and answer up
to about 50 questions, one after the other, shown only one question at a
time. The answers are saved in a database.
A fellow developer and I are discussing when is the best time to save the
answers. We have two approaches in mind:
Approach 1:
After each question is answered, the answer is saved in the database.
Sessions are only used to store the User ID.
Approach 2:
After each question is answered, the answer is saved in a session variable.
When the user has finished the entire survey, all the answers are saved at
once in the database. Also, if the user logs out, or if the session times
out, the answers answered so far are all saved in the database at once.
The amount of actual data sent to the database is the same in both
approaches, but Approach 1 have much more frequent calls to the DB, thus
creating an overhead of opening and closing connections. I'm not sure how
significant that is. On the oter hand, Approach 2 store a lot of data in
sessions. I'm not sure how bad a thing that is.
Which approach is better and for what reasons? I'd be happy to supply more
information if needed.
I am looking for a tool/product (commerical or shareware) to correlate
classic ASP pages (not ASP.NET) with timings of ADO calls made from
each ASP page. The information I am looking for are
T1, url = http://..../product.asp,
DB Server=SQLSvr1, DB Name=products
ADODB.Connection.Open 10ms
ADODB.Recordset.Open 189ms
...
T2, url = http://.../search.asp,
DB Server=SQLSvr2, DB Name=productindex
ADODB.Connection.Open 15ms
ADODB.Connection.Execute 350ms
...
It would be nice if the tool can automatically rewrite existing ASP
pages if necessary.
This would be a good performance monitoring tool for classic ASP
pages.
I'm using the following function, which uses a recursive call. every time when I get a conf it opens a record set. So increases the cusor count. Some times I'm getting the following error:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC driver for Oracle][Oracle]ORA-00604: error occurred at recursive SQL level 1 ORA-01000: maximum open cursors exceeded.
How can I avoid this ? Code:
Any body know of a resource that compares/benchmarks the expense (in terms of milli seconds, or server load) of using various programing options?
I know a lot of articles and forum posts reccomend best practices between functions and programming options, but I would be interested in some type of definitive benchmark to decide between various prgramming options, depending on the need.
For example, I can call a Recordset and quickly write it into an array, so that the connection can be closed even before I write the data to the HTML page. This would save conection time and server resources, but I'd like to be able to judge the worth when considering coding it.
Every time I do a Server.Transfer how expensive is it to the server? How much am I loading the server with Session varaibles? If I store some info in a cookie, but have to call it, how long will that take? Am I using up server resources by creating large arrays?
I developed a website that posts data to another url via the Inet object.
I should mention that the posting code is wrapped in a VB 6 dll, and that
dll is called from ASP. Code:
What's the difference between private and public functions in ASP? When should I use either?

I googled this but can't find any related topic.
I want to use the instr function, but return results from it depending on surtain functions, I can't realy explain so I'll show my example:
I have a string in wich some word I want to find might be in diffrent Capital Letters order, I want the Instr function to return all the values of the place of that word (avcourse I'll run a for and increase the starting point of the Instr func until it returns 0). The instinct thought is to use the Lcase or the Ucase functions, but in this case I don't know how to use them. In the same Idea I wanted to use the Instr Func with the trim Func, But Its realy the same principle if I just understood how to do so.
I am trying to call a function in asp to check to see if a varibale has a value stored in it if there is nothing wite the value NA into it. My code is
<%
Function NullValues(userField)
if userField = "" then userField = "NA"
end function
AccountNo = ""
Name = "sam clowes"
email = ""
AccountNo = (NullValues(AccountNo))
Name = (NullValues(Name))
email = (NullValues(email))
response.Write AccountNo & "<br>"
response.Write Name & "<br>"
response.Write email & "<br>"
%>
When I run this code ALL the variables are blank and nothing is output
the function
<%
Dim objXML, objXSL
Function ShowXML(strXML,strStyleSheet)
Set objXML = CreateObject("MSXML.DOMDocument")
Set objXSL = CreateObject("MSXML.DOMDocument")
objXML.load(Server.MapPath(strXML))
objXSL.load(Server.MapPath(strStyleSheet))
Response.Write objXML.transformNode(objXSL)
Set objXML = Nothing
Set objXSL = Nothing
End Function
%>
calling the function in an asp file
<%Call ShowXML("http://msn.foxsports.com/feedout/syndicatedContent?categoryId=142","nhl/xsl/news/teamNews.xsl")%>
the errors
1. the http:// part
2. and the ? mark
the error message says that the path has been typed wrong.
the user can key in variable A and B
then C is auto generated by C = A / B
so how and where should i write the C function??
Possibly a very simple question but how do I get a value out of an XML document so I can play with it in ASP

View Replies View RelatedI know the basic difference between a subroutine and a function is a
subroutine performs a task and a function performs a task and returns a
value. The Call keyword is required when using parens with subs with more
than 1 parameters. Parens around values passed are ByVal vs ByRef and is a
waste of processing if passed ByRef for no reason.
I am told there is no reason to ever use a subroutine as a function can be
used even if it doesn't return a value. While this appears to be true, is
there any reason why it's ever a bad idea to use a function, instead of a
subroutine, that doesn't return a value? Are there memory, performance,
etc. issues?
I am trying to locate information on how to call a sub within VBScript on an
ASP page but I can't locate generic information. What I want to do is
generate a page that will stay up but the information on it will change
based on a series of drop down boxes. I need the first drop down box to call
a second dropped down box based on the state that is chosen then city and so
on.
I have a column in the table which contains 2 full names seperated by "&" (e.g: Joe Smith & Jeff Scott) I want to display only the first names of the whole record in an asp page. Is there an asp function using which i can do this?

I’m trying to do something that I remember as very simple I'm trying to check that the value of a form text box is numerical using the isNaN function. The code I am using is:
<%
quantity = Request.Form("number1")
if isNaN(quantity) = true then
Response.Write "Your input was not a number"
else
Response.Write "Your input was a number"
end if

All I get is a NaN type mismatch error.
Is there a function to check to see if a string contains a space
Thanks
I was just wondering when using the mid function how does the assigment work when the length is longer then string itself? For example
test = mid(12345, 1, 10)
What would be the end result of test?Would it be 0000012345 or 1234500000 or 12345?
When I create a single character string
var str = "A"
'convert to ascii
num = asc(str)
Response.Write num ' 65 shows up
'when I have a whole string
str = "hello"
str = mid(str, 1, 1) ' return 'h'
num = asc(str)
'I get an error:
Invalid procedure call or argument:'asc'What can be done to fix this?
I've an array to store alphabets, in my code...in a random order. How can i use the Asc() function to get the equivalent Ascii of each alaphabaet of that array....
whenever i use ,
for i = 0 to NoOfElements
Response.write Asc("ArrayName(i)")
next
it displays 65, "NOOfElements" times (ascii of A)...on the other hand..i can't write
Response.write Asc(ArrayName(i))
since this shows some error...How can i solve this?
Depending on some situations, I or the user, need to execute a function (e.g., login, sending email, etc...) and then continue from the original place. How can I make one function to be available from any page from my site?
View Replies View RelatedI have a problem with max() function. The SQL is as follow SELECT max(group_no) as group_no FROM doc_groups. if I run the sql in MS SQL server, it will return correct result. However when I run in ASP file, there is no record return. I check with RecordCount property and it return -1.
