Distance Calculation
Aug 19, 2007
Dear All:
I have a problem in calculating distance's mileage.Eg: Distance from town A to town B is 10km, town A to town C is 20km and vice versa. I have a table named "Location" as per below:-
Town From , Town To , Distance
A , B , 10km
A , C , 20km
A , D , 30km
B , A , 10km
C , A , 20km
D , A , 30km
My question now is: if there are 26 locations, (Eg: A - Z), then I need to key in the distance one by one and it is very tedious. Because Town A to Town B is 10km and Town B to Town A also 10km.
Is there any method that Access will consider A to B and B to A is same distance?
Can we use crosstab to calculate?? and what is the step?
Pls help & thanks in advanced.

I would like to have a back-end Database on a host server and link a
front-end Database to the tables several hundred miles away. The problem is I have no experience whatsoever in doing this.
My questions are:
(1) Can tables be linked via the Internet?
(2) If they can, is this the best way to link the tables?
(3) If it is possible to link the tables by the internet or by some other way; how do I do it?
I really would appreciate any help you can give.
Kind regards
Eddie

I am trying to create a query that gives me a cummulative distance based on a previous footages. For example I am prompting the user to enter a Route. Along the route are several points having a numeric value. Each of these points along the route have a footage accociated to the previous point. I want the query to display the Route, each point along the route based on the users defined start and end point, show each backspan footage and provide a cummulative distance based on the progression of the route. Below is what I have created so far. Now I want to add a cummulative distance.
SELECT PED.ROUTE_1, PED.TERMINAL_1, PED.TERMINAL_1, Sum(PED.BACKSPAN_1) AS SumOfBACKSPAN_1
FROM PED
GROUP BY PED.ROUTE_1, PED.TERMINAL_1, PED.TERMINAL_1
HAVING (((PED.ROUTE_1)=[ enter route ]) AND ((PED.TERMINAL_1)>[enter start]) AND ((PED.TERMINAL_1)<[enter end]));
Thanks for any help.

Before I design an application in Access, I need to know if a certain task is even possible. I have a table of Physicians containing their names and addresses. What I would like to accomplish is to be able to provide an entry screen that would allow a user to input their zip code and have Access search for the physicians with a
1) 5 mile radius
2) 10 mile radius, etc.
Is this even possible within Access?

I am using Access 2010 and am developing a form where the user provides a full address - street number, street name, city, province and postal code.
I want a control to calculate the distance from this address and a fixed address.

However Instead of entering the postal code continually or selecting from the combo box. How do I set zipcode 1 and zipcode 2 based on fields in a form. I would like to use the current FROM (Default zip based on the current job in form) and TO zipcode [Project Postal Code] that is on the form at that time. Not necessarily combo box.
Currently you have
zip1 = Me.Combo2.Value
zip2 = Me.Combo4.Value
I want Zip 1 to be Default zip (however I can still change it if needed) ZipCode field is [Project Postal Code]
Here is the full code:
Private Sub Command6_Click()
Dim zip1 As String, zip2 As String
Dim sResponse As String
Dim sLink As String
On Error GoTo Command6_Click_Error
zip1 = Me.Combo2.Value
[code]....

Hi All.
I have 3 tables in Access:
tblCurrency (Fields: IDCurrency, CDate, CRate)
tblOrder (Fields: IDOrder, OName, ODate)
tblCalculation (Fields: IDCal, Rate1, Rate2, Rate3, COrder)
IDOrder is related to COrder with "One to Many" connection.
I have Form frmOrder, based on tblOrder. For Example Form has 1 record:
IDCal OName ODate
1 XXXX 2005.10.24
For this record related table has 2 records:
IDCal Rate1 Rate2 Rate3 COrder
1 10 3.5 15 1
2 6 4.2 12 1
tblCurrency for Exapmle have one record too:
IDCurrency CDate CRate
1 2005.10.24 0.2
In frmOrder I have textBox txtRate. Here I need to be calculated:
=Sum (Rate1*(CRate from tblCurrency Where tblCurrency.Cdate = tblOrder.Odate)+Rate2*Rate3 for Each record related to tblOrder).
By Exapmle: (10*0.2+3.5*15)+(6*0.2+4.2*12)=106.1
Please help with expression.
Thank You in advance.

hey i hope some one can help me...
I am making a database for products and suppliers. Many suppliers can supply each product.
The product details are in a table called products, the suppliers details are stored in a table called suppliers and the suppliers offer for each product is stored in a table called prices.
the structure is as follows:
Table: Products
Product Name
Trade Price
Table: Suppliers
Supplier Name
Table: Prices
Product Name
Supplier Name
Supplier Offer
I have form that shows the product details and a subtable linked to the table:prices.
The problem
I need to add a field in the subtable called "Percent off trade" which is the trade price - supplier price / trade price * 100
i created a query showing the same records as the prices table plus the field "trade off price" and set the Field to:
Percent Off Trade: ([Forms]![Products]![Trade Price]-[Prices]![Supplier Price])/[Products]![Trade Price]*100
But this doesnt give me the correct percent :confused:
I hope i have explained this query and would really appreciate anyone who takes the time to suggest anything that could help
thanks in advance!

How can I multiplicate two numbers from two columns in a subform, show their result at the end of the row and then calculate sum of those results on the main form. This is something what I know how to do but the problem is following:
The total sum on the main form should be multiplicated wit 0,5 % and then reduced for a value of a specific row sum. It should be something like this: (Sum of rows sum * 0,5 %) - Sum of the specific row = Total sum on the main form. And all of this should be on a report too.

How would I query just for paper and not metal?
I am also going to need a query for the lowest price and the highest price.

This is probably an easy calcualtion I am overthinking...
I am trying to make a query where I am calculating the "Total Value" of each customer's order of each item for the current week. The item "my company" is selling is fish, sizes small, medium and large all at different prices. I'm not exactly sure what they mean by "Total value", but I assume I take the cost times the quantity...but then what is the difference between Total Value and total ordered (in dollar amount)? Any suggestions?

I wonder if someone can point me in the right direction with a calculation problem. I have never done calculations in access before but want to make a balance sheet for a club account that I am designing. Very much in its trial stages, I have a form with three currency text boxes in it, set up as continuous. MoneyIn and MoneyOut are in the main form whilst Total is in the footer. All I want is to be able to put in a value in MoneyIn or MoneyOut and for the Total to update. Problem! I dont have a clue where to start! :rolleyes:

Here is a part of my database nicely zipped for you guys to help me with.
whats happening is when i click the totals button whatever the highest cost option that is selected with a "Y" should be displayed in the totals text box.
example:
Installation of heating system - "Y"
Replacement Kitchen and Bathroom - "Y"
Total should be "£90"
The code behind the button works fine with every choice but not the installation of the heating system. When this is selected "Y" the code seems to be ignoring it.
Any help will be much appreciated.

I am trying to type a code based on 1 & 2 criterias. However, I am having a problem on the first criteria because it is adding 8 hours when it shouldn't. Can someone help to either fix my code or write a new one? Thank you very much!
Criteria 1: If the day_of_wk is 1, calculate time-reg_time/60, If the day_of_wk is 1 and time is less than 0, calculate time-reg_time/60+24
Criteria 2: If the day_of_wk is 2, calculate time/60, If the day_of_wk is 2 and time is less than 0, calculate time/60+24
My code: pre: IIf([day_of_wk]="2",[time]/60,IIf([time]<0,([time]-[reg_time])/60+24,([time]-[reg_time])/60))

Hey,
I noticed something strange in access 2000: sometimes it takes a long time to calculate a report and other times it goes rapidly. I don't see any process taking a lot of CPU %.
When i do the same thing in Access2003, it goes rapidly every time.
Can anyone help me?

Hi All
I am seeking the solution to a problem with calculating stock adjustments
We use a job code which comprises several stock items and labour which = a $ value
I have a form "work in progress" where I enter all the job details including the job code, the aim is to reduce the individual stock items from a table "Stock" when the job code is entered.
JobCode 25WE = 1 x power point, 25metre cable , 9 x clips
I have tried several methods but to no avail, is there a way of doing this
Thanks in advance

Well, I hope this is simple, but for some strange reason, very difficult for me.
I'm having issues setting up a calculation between 2 tables. for example:
Table1 ID Quantity
Table2 TransID Used
The "Quantity" from Table1 is a set number but the "Used" will change. all I want to do is have a Form and Report that will subtract the "Used" from Table2 from "Quantity" from Table1.
I've tried: =Table1.Quantity - Table2.Used
=Quantity - Used
what am I doing wrong? all my attempts have failed, even though I have setup a relationship between the 2 tables.
any idea?
thx

see this thread...
http://www.access-programmers.co.uk/forums/showthread.php?t=69237
hi everyone,
can we please start this thread again...
- since may'04 (when we started this thread), i have tried many of the suggestions in the replies to this thread, and as i am no expert in access i repeatedly ended up at the beginning.
- if look at the history of this thread, you will notice that i need just a very small and simple db.
- since may'04 i did alot of reading and 'self-study' on access, and i'm sort of "getting the picture" now, but could find nothing to sort out my problem.
- most of you guys seem to know alot! about programming in access, and i have great respect for you... but if anyone could please suggest something SIMPLE! to sort this problem i'm having. (or is this wishfull thinking on my part?) :)
have a good day !
Regards,
Piet.
