Finding The Hypotenuse Of From Two Pairs Of X,Y Coordinates


I have a map with several waypoints and would like to find the distance between any of these two waypoints. Sounds simple, but I have having an issue with the later parts of the excel file. Let me explain further.

There are over 100 waypoints on this map we have. Each waypoint has an, seemingly arbitrary, X-coordinate and Y-Coordinate. However, if you divide the coordinates by [X], they turn into miles. It should go without saying that finding the distance between two waypoints is rather simple mathematically, but I having an issue figuring out how to pull two random waypoints and having the distance automatically calculated.

So far, I just have column A with the waypoint name and with column B and C having the X and Y coordinates respectively. Is there anyway I can create some sort of call function that when two waypoint values are entered it would automatically calculate the distances?

Numbering For Coordinates
how to get a single cell (C2) and (D2) to make the numbering format go from (## ## ##) to (######).

The Excel spread sheet is a coordinate converter, designed to take Degree's minuets seconds and convert it to Decimal Degrees, the formula is set up and work Great, but every time I copy and paste the coordinate to the excel spread sheet, i have to manuelly erase the spaces between the numbers so the formula can work properly. How can i get the cell to automatically delete the space between the numbers to save me time.(I.e 29 35 42.34325 -to-> 293542.34325)

Calculating Distance Between Coordinates
i use a Trimble Total Station Survey equipment, This is used for suveying and measuring distances between points on jobs. These points can be exported onto the pc as a text file and imported onto excel, the file has a northing and easting to locate the point these are comma separated.

I would like to know if excell is capable of working out a distance betwen two of these such points by using the two pairs of northing and easting coordinates. The maximum distance between two points is no more than 50 meters. If for example when imported onto excel point 1's coordinates are locted in cells A1 and B1 and points 2's coordinates are locted in cells A2 and B2.

Calculate Angle From X, Y Coordinates
I have a userform, on it is a very large command button with a picture of a map loaded on the button. The button is 500 width(X) by 500 height (Y), so the center of the button would be at the location 250 (X) by 250 (Y). The button is coded for mousemove to get the X,Y cooridates and when you _Click the button a textbox gives the distance to the point(mousemove) from the center of the button. All that is good, but now I'd like to find the degree of the point referenced to a compass, ie, if the point is at 250 (X) and (Y) is less than 250 then the point would be due north at 0/360 degrees and if the point (Y) is greater than 250, it would be south of the center of the button. I hope this make sense. It's been a long time since trig. I've been searching but can't seem to find the correct formula to figure this out.

Here's the other problem, I'm doing this in powerpoint so I'm not sure if cos or tan functions are loaded in this program. I am posting this in the xl forum because I figure that's where most of the people who could figure this out are. If this is in the incorrect forum I can try to move it,

Matching Pairs Of Data
I'm not sure if it's possible to do this, but I have three lists of data. One is a complete list (for example, the numbers 1-25).
The next list is a subset of the complete list (e.g., 1,3,5,7,9). Attached to these (the subset list) is another list (let's say letters, so A goes with 1, B goes with 3, etc). I want to physically move the paired entries from Lists 2 & 3 so that List 2 matches up with List

I have:

1|1|A
2|3|B
3|5|C

5|9|E

Count Pairs In Range
I am trying to analyse a set of variables in my dataset.

The variables I have are numbers which are organised into a single column.

I want to count the number of times different variable pairings occur within my data.

An example dataset of mine is: 1,2,4,2,1,3,5,3,2,1

As the dataset contains 5 variables (1,2,3,4,5) the potential combinations are: 1,1; 1,2; 1,3; 2,1; etc.. with 25 in total.

I want Excel to move through this column starting with the first two cells and step down 1 cell each time and then tell me the number of times each of the combination occurs.

ActiveCell.Address - Discarding Fixed Coordinates
I'm attempting to write a piece of code that builds a formula dependent on the location of the cell it is being created in. The relevant line of code currently reads as follows:

ActiveCell.Offset(0, 5).Value = "=" & ActiveCell.Offset(0, -5).Address & " & " & ActiveCell.Offset(0, -6).Address

Which when activated in cell A3, will enter the formula =$A$3 & $A$2

However, I would like to know if there is a way of automatically building a formula like this, only without the absolute references. Reason being, this formula is used in a large table, which is sorted in date order automatically when the sheet is activated. Since the code generated will point at the row it was generated on, when the table is sorted, this formula will calculate the incorrect result.

On the target sheet, I have a set of 200 geographic coordinates longitude and latitude (in decimal degrees). Each pair of coordinates coresponds to a geographic site.

On the reference sheet, I have a set of 900 geographic coordinates longitude and latitude (in decimal degrees). Each pair of coordinates coresponds to a geographic site. Note that of the 900, 200 are the same from target sheet, other 700 are different sites.

Using the spherical law of cosines, I can calculate the distance between a set of coordinates on target sheet agianst a set of coordinates on reference sheet. This allows me to see the distance from one geographic site, to the other. This was easy. The formula I use is as follows: ....

Getting Max Value Of A Point Inside A Square Defined With X,y Coordinates
I have a square which is defined with x,y coordinates (roughly 2000 points), and for each point I have a value. And I have to divide this square in to 9 equal sub grids, and find the max value in each sub grid. I have all the coordinates for the sub grids. But I can’t get the max value of the specified cells.

I am thinking something like this:

if 0<x>10 and 0<y<10 then it is sub grid 1 and I want to find the max value there
and if 0<x>10 and 10<y<20 then it is sub grid 2 and so one…..

Button Position/Coordinates On Worksheet. Discrepancy Between Versions
Add Multiple Buttons That Select Row Of Housing Cell. One of my Macro's places a button on a sheet using Top/Left;

Set sbut = Sheets("Listings").Shapes.AddFormControl(xlButtonControl, _
Range("J" & count).Left, Range("J" & count).Top, 50, 12)

When I try to find the row of the clicked button using the following code;

Range(ActiveSheet.Buttons(Application.Caller).TopLeftCell.Address).Activate

The code behaves differently in Excel 2002 and 2007. In 2002 it returns the row the button sits on, but 2007 returns the cell above the button. This could be because the workbook is an XLS running in Excel 2007 in compatibility mode? Is there a way to "nudge" the button down a little after it has been placed using .top/.left ? Or is the only way around this something like;

Range(ActiveSheet.Buttons(Application.Caller).TopLeftCell.Address).Activate
count = ActiveCell.Row
If Application.Version >= 12 Then
count = count + 1
End If

Is this a bug, or something that I am doing wrong ? The workbook needs to be a .xls to ensure that it works in older versions of Excel.

Matching And Sorting Non-Identical Row Pairs
I have a database with 6 columns in play (there are actually other columns but they are not relevant). I'll call the columns A through F. I would like to be able to match certain counterpart rows together, do a sort placing the counterpart rows adjacent to one another, and then count how many pairs I have. (Some rows will have no counterparts.)

Here is a micro-illustration of the database:

______A______B______C______D________E_____F
R1___01-03___54____959____nsneakr___24____yes
R2___01-04___67____454____adidaht____53____yes
R3___01-10___42____344____calb3wd___11____no
R4___01-19___67____454____adidaht____53____no
R5___01-25___54____959____nsneakr___24____yes
R6___02-02___54____959____nsneakr___24____no
R7___02-14___54____959____nsneakr___24____no

I basically need to devise a formula or script that pairs together two rows that fit the following criteria:

1) The rows are identical in Columns B, C, D, and E.
2) The rows are not identical in Column F (i.e., one half of the pair should have "yes" and the other half should have "no")
3) The rows are as close together as possible according to the date sequence in Column A. For example, Row 1 should pair with Row 6, and Row 5 should pair with Row 7. Row 1 should not pair with Row 7, and Row 5 should not pair with Row 6. **This criterion seems tricky because R5 and R6 would technically fit the requirement for pairing, were it not for the fact that R1 comes earlier in the sequence.**

How To Use One Cell To Match Pairs Of Cells For Missing Items
We use a program at work to check items out to individual people but sometimes an item is missed and it takes forever to manually look for who it is. In the attached example, (keep in mind there might be more than 100 people on this list...this is just two people), the first 2 items are a pair (radio and radio case) and the second 2 items are a pair (laptop and laptop case).

Id like a way (condition formatting) to flag a person who has one item from the pair checked out and not the other. (Ive manually highlighted one person who only has one of the paired items...id like this to happen automatically)

EDIT:: If the first person were missing the radio in this example, his name would be highlighted on the line with the matching pair...cell D1 (radio case)

Other information:

Radios will always be RFAMRC***
Radio cases will always be RFAMF****

Laptops will always be RFAMTD***
Laptop cases will always be RFAMTE***

Nested AutoshapesL: Display Several Pairs Of Boxes, Which Consist Of A Descriptor Box And A Value Box
I have a problem when using autoshapes. Above a display of columns of data, which are of different widths, I need to display several pairs of boxes, which consist of a descriptor box and a value box. If I use formatting in cells, I am constrained to use the width of the columns below. So I will be using autoshape rectangles. No limit on box widths and I can link each one to a cell to send text to them. So far so good.

However, I would like to contain a group of these box pairs within another autoshape. When I do this, if I fill the outer autoshape with colour, I have the choice of making the colour solid, which means you can't see the inside box pairs at all, or semitransparent, which allows the boxes to loom through a fog of the outer colour. What I would like is for the inner boxes to show properly, and fill only the space between the inner boxes and the rim of the outer autoshape

That helps me find the value in the last row that actually has data in my spreadsheet. This is great, but I want to try to accomplish the same thing without vba. In other words, in cell A3, I always want the value that is in the J column, but the last row that has data. (In other words sometimes the last data row ia 97, sometimes it is 23.) Since the value is always changing this won't be vlookup. Is there another excel function that can find the end without the use of vba?

This might seem goofy to need to do since I already know how I can in vba, but in my (admittedly pathetic code) I keep have an endless loop and if I can figure out a way to get this value on the ss.

Finding Duplicates ...
I have a workbook that I want to find if I have any duplicate numbers in a specific area.

The area of cells that I am checking is C3 through AO70

I am checking for numbers between 95 and 800. These are all ID# of individuals and not all the numbers between 95 and 800 are used. IE: 97 through 100 are not used ect.

I have already written a macro that does something else and I can use it to check each number as it comes up. However, once the number comes up I don't know how to use it to check the area.

If I can check all the area at one time to find duplicates it would be easier.

I do not know how to do either way but I can adapt my macro to whatever way is possible.
