Help needed to add ecommerce functionality

i am in the process of creating a website using dreamweaver
cs3. Almost completed. i have some e books with master reseller
rights. So i want to sell it through my website. i cannot spend
initial investment for 3 party sites so i thought of going via
paypal. but the site instructions aree to complicated.
1.how do i integrate paypal into my website with shopping
cart feature?
2. how do i allow people to download the files only after
they payed for them?
3.i have like 20 ebooks which i can sell. So how do i give
people the option of selecting what they want(adding to cart all
the individual ebooks they select) and then proceeding to check
out?
4.in paypal website they said about something like encryption
for security.not the ssl but something like to prevent users from
modifying the code and submitting wrong amount. is it actually
necessary?

Hm.. if you feel that way, you might want to hire someone to
do this.
Setting up a PayPal shopping cart is about the simplest
method of creating a
shopping cart site.
> 1.how do i integrate paypal into my website with
shopping cart feature?
This is a large general question which would be answered by
following the
instructions on the PayPal site. However, see below re.
digital downloads.
> 2. how do i allow people to download the files only
after they payed for

PayPal doesn't provide for digital downloads. I can
personally recommend a
service called Payloadz (www.payloadz.com) which works with
PayPal and
delivers your digital items automatically.

give people the

individual ebooks they

I'm not sure how that would work with Payloadz/PayPal, since
I only sell one
item. The answer should be on the Payloadz site, or else a
support ticket to
them should get you an answer.

I'm not sure if it's necessary, but you could just be safe
rather than sorry
and use the encryption. PayPal support will be able to answer
a question
like that.

Help needed in writing a function.

I am using Oracle 11g and SQL plus. I am a complete newbie, so I need some help here in writing a function. I guess my question is more about writing the trigonometric functions within the function.
latA, longA latB, longB // these are the four input parameters,
theta = longA - longB
distX = sin( latA * PI / 180) * sin ( latB * PI /180) + cos ( latA * PI/180) * cos ( latB * PI/180) * cos ( theta * PI / 180)
distY = acos(distX) // this is arc cosine
distZ = distY * 180 / PI // PI refers to the mathematical PI
distP = distZ * 60 * 1.1515; // this value should be returned. Of course the intermediate variable names don't matter.
Please help. Thanks.

CREATE OR REPLACE FUNCTION fucntion_name(latA IN NUMBER, longA IN NUMBER, latB IN NUMBER, longB IN NUMBER) RETURN NUMBER
IS

Help needed to add an image to a datagrid cell in actionscript

Morning all,
I am still quite new to flex development and I have an application which uses xml to populate a datagrid. One of the row columns should display a small image but I don't know how to do that.
Can anyone show me how to add an image to a datagrid cell in actionscript?
I've added a sample of the code I have written already below. Any help would be much appreciated.
Thanks in advance,

you cant just set image object to itemrenderer, you need to use classfactory.

Help Needed With "Extend Marker" Function Not Working

I have several Clips and used the "DV Start/Stop Detect" function to find the time code breaks, which seems to work well. I've now got a clip full of Segment markers.
The problem arises when I try to use Extent Markers "Option + `" to make subclips. When I put the play head on a subsequent marker, the Marker/Extend function is grayed out.
Extending a marker that I have created using the M key works perfectly.
Why can I not use the Extend function on Segment Markers?
Any help on this is greatly appreciated. I have 30 odd clips that I need to set up segments for, and doing it manually will add hours to my workload.
Thanks
Gary
Dual G5 2.5 GHz Dual Core, 2.5 GB RAM, 500 GB HDD Mac OS X (10.4.3) Final Cut Studio FCP 5.0.4

Thanks for the reply.
I am completely aware of items 1 through 3, and never Extend markers in the Timeline. Only the Viewer.
To perform an Extend Marker and avoid headaches, load the captured clip - the one with the video icon in the Browser - into the Viewer. Then, as you scrub along in the Viewer, Option-` as needed.
That is precisely what I am doing.
To Extend the marker I first double click the clip to load the entire clip into the Viewer, where all the Section markers are displayed. I then check Mark>Markers>Extend and the function is grayed out. However, if I move the playhead one frame prior to the Section marker, the previous Section marker extends to the frame prior to the new play head position.
If I do this with manually entered markers (using the M key, creating Marker 1, 2, 3.... in sequence on the Viewer timeline), then the Previous marker is extended to the frame immediately prior the the current play head position - i.e. from Marker 1 to Marker 2. I do not have to move off the Marker 2 position to be able to extend Marker 1.
Also, simply selecting all your Markers and either dragging them to another bin (or pressing Command-U) does not produce the needed subclips?
Of this I am also aware. I find the Command-U process just confuses the issue, creating more clips to manage (others may disagree). I prefer to simply drag the "Subclips" directly from the Main clip into a Timeline.
Because you're doing all this to get subclips, right? Or wrong?
If I understand your reply correctly, I think you misunderstood my problem. I have been using subclips for several years, and find them VERY useful, especially with multi-camera shoots. So, I am quite familiar with creating and extending markers.
I just started experimenting with the Detect feature and find it works quit well (most of the time). My problem is that the Segment markers created by the Detect process, do not perform the same as manually place markers, as far as the Extend marker function is concerned, anyway.
BTW - By using the TC display in my Panasonic PV-GS400 Camera, and sending the FCP video via Firewire to the camera, the camera displays the TC on the captured clip, which I then rename the marker to for TC reference. As long as the Date/Time on the cameras are properly synced, syncing clips in the Timeline is a breeze!!
Anyway, to clarify, my process is as follows:
1. Capture a clip.
2. Display the clip in the Viewer
3. Select "DV Start/Stop Detect" and watch as the section markers appear in the Viewer.
4. In Viewer, place play head on the first Section marker
5. Press the M key to Edit Marker.
6. Change the Name of the marker to the timecode of the Marker now displayed in the Camcorder window.
7. Use Shift-Down Arrow to move to the next Section Marker
8. Press Option+` to Extend the previous marker - which does not work and is grayed out in the Mark>Markers>Extend menu.
9. Back to step 5.
This process works perfectly with manually created markers. Because the Extend works if I move the play head one frame prior to the current Section marker, this tells me there is something "special" about the Section marker that disables the Extend function, unlike a manually created marker.
BTW - If I delete the Section marker, and create a manual marker at the same frame, the Extend marker function works again. Again, indicating that Section markers are different somehow from manual Markers.
Hopefully, this wordy explanation of my process clarifies my problem.
Aside: The clips are supplied to me by a customer on a 500GB FW800 drive. FCP5 was used to capture the clips from the original Tapes (which I do not have access to). I am the editor for the project.
Thanks again for the reply. It is greatly appreciated. If there is any other info that I have missed that will help figure this out, please let me know and I will post a response a quickly as possible.

Help needed in OBIEE Rank function

Hi All,
I have a request having Period, Amount,Branch code. In this i need to figure out the top N ranks (N is the user input which is populated using Presentation variable) based on the amount.
Then in the final output it should display as Top N branches with its previous period's data.
For eg: If we try to rank the amount for period=31-dec-2010. The final output should be displayed in pivot table as
*(Branchname in Pivottable section)*
* (Period to be displayed columnwise) 31-Mar-2010 30-Jun-2010 30-Sep-2010 31-Dec-2010*
Amount (Measure)
Can you guide me to achieve the above request?
Is there a way to calculate rank based on two columns?
Kindly help me.

Very urgent help needed in activating a function module

Hello experts.
I had a standard report and i copied into an z report. i need to change some field output , and that field is there in a standard function module.so i copied that fun module into z fun module and stored in a new fun group. Now it is showing the error in the z fun module. include in the fun module is giving the error stating that it is not existing. please help me in coping the standard fun module correctly . please its very urgent.

Hi,
You should not copy a Function module alone, as it will have some dependant INLCUDES and global data in TOP include of the function group.
SO if you want the function module copy the entire Function Group into Z function group.

Help Needed to add Hyphen in REGEXP_REPLACE

Hi All,
I need a help to add hyphen in my select criteria so that it does not filter the hypen.
I am using below REGEXP_REPLACE to get my output, everything is fine now except the Hyphen (-) character is not recognized.
select REGEXP_REPLACE('abcd-efgh123{}$(),', '[^[a-z,A-Z,0-9,(,),{,},_,$,.,'',[:space:]]]*','') from dual;
Can you please help?
Thanks

The hyphen has a special meaning inside a regular expression. You can use if you make clear that the extended meaning is not possible in this case.
example
with testdata as (select 'A-C' txt from dual union all
                  select 'X-12' txt from dual union all
                  select '1''2' txt from dual union all
                  select 'ab#' txt from dual union all
                  select '()' txt from dual union all
                  select 'a b*~' txt from dual union all
                  select 'ab' txt from dual union all
                  select 'abcd-efgh123{}$(),' txt from dual
select txt
      ,REGEXP_REPLACE(txt, '[^[a-zA-Z0-9(){}_$.''[:space:]-]]*','') keep_chars
      ,REGEXP_REPLACE(txt, '[[a-zA-Z0-9(){}_$.''[:space:]-]]*','') remove_chars
from testdata;
TXT     KEEP_CHARS     REMOVE_CHARS
A-C     A-C
X-12     X-12
1'2     1'2
ab#     ab     #
a b*~     a b     *~
ab     ab
abcd-efgh123{}$(),     abcd-efgh123{}$()     ,I removed the comas. In case you want that char also to be removed just add it somewhere. It is not used as a separator in this specific case.

Help needed in building a function

Hello,
I am using Oracle DB 11g.
I am writing a function.
create or replace function func(tab VARCHAR2) RETURN VARCHAR2 AS
cursor c is SELECT column_name
FROM all_tab_columns
WHERE table_name =tab;
begin
//some statements
for i in c loop
flag=1;
//some statements
end loop;
//use the same c cursor query
if flag!=1 then
//repeat the block inside the for loop;
end if;
end;
Function works fine.
Now once the for loop ends,what i want is if it doesn't enter the for loop, then for just for once enter the if condition for
any column from the table and repeat the process, which i am doing inside the for loop.
But here i am finding repetition of same query and the block of code.
Is there any way i can avoid that?
Thanks

How about you start from scratch and explain the business problem you are attempting to solve. Not a portion of a technical implementation that doesn't seem to make any sense.
Start from the beginning, no code ... just "i have a situation where i need to .... ".
Should be a lot more productive.

Help needed with looping a function

Hello experts,
I am in a bit of a mess of ideas,
I have a form with various search fields.
based on the values i am passing, i am returning some values back to my form
below is my function
CREATE OR REPLACE function LOTTO_EROUTES.f_forecast(p_ret_num        in varchar2,
                                                    p_item_id        in number,
                                                    p_curr_date      in date,
                                                    p_expected_stock out number ,
                                                    p_actual_stock   out number,

                                                    p_prev_date      out date ,
                                                    p_range          out number,
                                                    l_settled_avg    out number,
                                                    p_coefficient    out number
return number is
l_forecast_num number;
l_curr_cdc varchar2(6);

l_forecast_err varchar2(50) := 0;
l_game_id number;

into l_game_id,p_coefficient,p_range
from items
where item_id =p_item_id;
l_curr_cdc := ltrim(rtrim(to_char(f_get_cdc_num(p_curr_date),999999)));
l_prev_cdc := (l_curr_cdc - p_range);
p_prev_date := f_get_cdc_date(l_prev_cdc);
select count(serial_number)
into p_inst_settled
from LOTTO_INSTANT_TRACK
where game_id = l_game_id
and retailer_num = p_ret_num
and status = 'Settled'
and cdc between l_prev_cdc and l_curr_cdc ;
l_settled_avg := ceil(p_inst_settled / p_range);
p_expected_stock := ceil(l_settled_avg * p_coefficient);

return l_forecast_num;
exception
when others then

return l_forecast_err;
end;
/Now in my function i am passing 1 single value for p_ret_num(retailer number), i value for p_item_id and p-curr_date which is default sysdate.
now i should be able to pass all retailer number and return those values accordingly.
I am thinking of having an LOV that will have "ALL" option whereby the user will select and it should return all its corresponding values.
I know i should be having a loop but don't know how to do that. Can anyone guide me plz.
Thanks

not using cursor for performance issues. well from what i've learnt.
yes, exactly. each and everytime its just replacing the values in the first row itself.
