On Error Resume Next, How To Show The Rest Of The Page
I'm on the last piece of this project, when a user goes to this page "myfolder.asp" it shows the contents of their folder.
If they don't have one created yet, I want to give them a friendly message: "You have nothing in your folder!" , and continue with the rest of the HTML code, but then ignore the Repeat Regions and dynamic text thats inside the HTML.
Right now I have it woking if the table exists, it shows the records. If I delete the table, I have this message at the top of the screen and nothing else: "You have nothing in your folder!"
Here is the code:

I've a query on On Error Resume Next. I've explained what I understand for each case, I'm not sure that this is true.
Case:
1] Used in Function/Sub: will resume to the next statement in the
function or sub; but will not affect the error out side of the functions
2] Used at the top of the asp page: will affect all the page code and
will not affect the function/sub in the page at all.
3] Used in the page where ever required:?

I put the On Error Resume Next command as the very first line in my ASP
pages, which may contain various inc files and sub-routines/functions, so
that I can try and stop the dreaded DB error messages displaying to visitors
and would-be hackers.My question is, does this one statement at the top of the page cater for all of the code that might be executed in the page, in the include files and in
sub-routines/functions or do I have to put the statement in certain places
as well?The reason I ask is that I'm sure if I get one of my include file names
wrong it brings up an error rather than going straight through and
displaying a funny page.I hope I don't have to put it in various places as I like to have this one statement so that I can flip back and forth between live and dev time and
having to go into 'x' amount of pages to flip between these 2 states would
be tiresome.

My code works when the table is not found. But when the table is found it doesn't do the else part..Code:
Dim oConn
Dim oRs
Set oConn = Server.CreateObject("ADODB.Connection")
oConn.Open "Store_Form"
Set oRs = Server.CreateObject("ADODB.Recordset" )
elseif campo = "txtAN_GEN" then
on error resume next
Set oRs = oConn.Execute("SELECT * FROM 00_MOD48")
If err <> 0 then 'If table not found
GetFieldValue = "00001"
else
GetFieldValue = "150"
end if

I am using On Error Resume Next to allow my application to deal with errors accessing the database, i.e. if the DSN-less connection doesn't work then it tries the DSN connection and this is fine.
What I want to find out is how can i stop the rest of the page continuing after errors, in essence I want to cancel the On Error Resume Next statement after the database connection stuff is done so that errors will stop the page and I can debug them.

I have a piece of code that i created. It actually works as it should. The only problem is the objrs2.update causes an error-duplicate primary key. However when i check the database it has done what it should.
I then tried to use on error resume next, but it keeps timing out and i do not want to extend the time limit. Does someone know how to get round this? Code:

Is there a way to avoid On Error Resume Next for:
cnn.Open strCon
SQL = "EXEC Customer @txtEmail='" & email_address & "'"
set rs = cnn.execute(SQL)
'On error resume next
rs("email_address")
'// This record does not exist thus throwing up an error. I could use On
Error to resume and then do this
'// If rs.eof or rs.bof
'//
.....But I hate this convention as I find debugging a problem. Is there a
better way?

This has been puzzling me for very long time and no where has
talked about the scope of a 'On Error Resume Next' statement.
When we program ASP(.NET) pages then we usually like to let
ASP(.NET) stop at errors and report back to us. However there
are parts of our scripts that we know an error will be thrown
and we encapsulate that area inbetween:
On Error Resume Next
Err.Clear
'Try block
If Err.Number Then
'Catch block
End If
On Error GoTo 0
This is similar to the infamous try {} catch(e) {} blocks in
Java/C++, etc.
If we forget the last line 'On Error GoTo 0' then our ASP(.NET)
scripts runs over all errors thrown and we find it hard to
find bugs. So the big question is, does 'On Error Resume Next'
go out of scope when it's written inside a block
(eg. Function)?
Function Function1()
On Error Resume Next
'Our code
End Function
When the Function1 call returns, does the outside calling scope
automatically stays as it was (On Error GoTo 0)?

I need to know how to make it possible for someone to send me a .gif or jpeg image through a form, by using a browse button etc.
Basically so after they have selected the picture they want to submit (by clicking on browse) and after they have filled out the rest of the form, when they submit it I would like the image selected to upload and be sent to me (with the rest of the form).
I have already got the rest of the form, all I need is the 'field' where they will select there picture, and the script that will enable it to upload.

I have a basic asp page running that is very slow it has to crunch some info
and when a user hits submit it can take a minute or more for a response. So
what I did was call a second page that should show a gif that is asking them
to be patient.
Unfortunately this never shows (See below). I have tried
other ways as well, but I have been unsuccessful in getting the gif to show.
This has to be simple but I'm not a skilled asp developer so I don;t know
how to do it. Anybody have any ideas?

The web page has page1.asp, page2.asp, page3.asp, etc... However, When we type http://www.myserver.com, and go to different pages, the URL will be unchanged. How to do that? Usually, it will be http://www.myserver.com/page1.asp, http://www.myserver.com/page2.asp, etc..., with the actual page.

Some of JPG files sitting in the same folder show up OK on an HTML page,
while the other do not as if they are not there or their name is misspelt.
Tried low-upper case in an ASP page, and in the files names - same result
Then I noticed that the same files do not show up in the preview pane in the
Windows Explorer althought they still are described by Windows Explorer as
valid JPEG files.
These "wrong" files are not necessarily bigger then the good ones and in
Microsoft Photo Editor they all (good and bad) show up well and they all are
118 Pixels/cm and True Color (24 bit)
What might be wrong with these files? If there is not direct answer, perhaps spmeone recommend me a correct newsgroup?

I'm working on an asp page where I need to be able to click on a link and then show or hide a section of the page. Kind of like folding markers. I can do it by simply refreshing the page but I'd prefer for it to just open and close. Is there a way to do this?

I have set up Index Server in IIS to search my intranet. I've installed the Adobe PDF filter so that words from PDF files are included.
I can get results from PDFs when querying the catalogue in the Windows console. However, I have tried various ASP Search pages and they all ignore PDF files from a browser (even though the scripts include the pdf extension).

I thought this is more of an IE issue but i've had no joy on that group
perhaps somebody here will have a clue.
If i click a link to a web page embedded in Excel (97 OR 2000) i get the
standard error page displayed by IE (you know, the 'cannot find server or
dns error' page).
Turning off 'show friendly http error messages' alleviates this.
(Unfortunately this is the Windows default setting!)

I'd like to discuss the concept of creating an error page which will handle the website content display. I need it for Search Engine Optimization. The problem is that SE does not read pages with querystrings like:
website.com/mypage.asp?id=123.
Therefore, there is a solution to it to make a link look like website.com/mypage/id/123 (which does not exist), and error page will display the content of website.com/mypage.asp?id=123 page, if url is website.com/mypage/id/123...Do you think that is a good practice to implement? Can anyone show the example? Should I use Msxml2.ServerXMLHTTP to pull another webpagecontent?
