Display The Path Result From A Floyd Algorithm Matrix Output

Aug 8, 2009

I want to display the path result from a Floyd Algorithm matrix output..

You can download the excel file here : http://ifile.it/lw4tgic
It consists of 1044 nodes, and we need to find the path between 2 nodes for ALL pairs..

Now, to find the path between 2 nodes, we need to :
1. Find the resulting cell of corresponding 2 nodes (y to x = z)
2. Update the path with that value (y z x)
3. For all the direct pairs in the current path (yz, zx), find the resulting cell
4. If destination (x) not the same with result (z) then repeat step 1 for that pairs.
5. repeat until x = z for all pairs.

Maybe it's better if i use an example....
we'll use T01 to E78 as an example

T01-E78 = if you look in the table,
y (vertical) = T01,
x (horizontal) = E78
z (result) = E77, so

T01-E78 = E77, so path = T01-E77-E78

check if result of T01-E77 = E77 (x = z?)...........................

I am looking up a risk matrix to return the risk rating... it is very simple, it works on one sheet, but on a different sheet (looking up different data, but same basic format) it returns exactly the opposite rating.

My formula is: =INDEX($G$6:$K$10,MATCH(I19,$G$5:$K$5,0),MATCH(J19,$F$6:$F$10,0))

Here is F4 to K10

I have data validation on I19 and J19 based on the cells below

Consequence

Priority Very Low Low Medium High Very High

[Code] ..........

BUT... when I put Very Low and Very Low in the two cells (I19 and K19) I get Very High as the return.

column I row 11 has a functional argument that simply states to display the output as .843 I need to edit it to .844 and I cannot seem to find out where or howto edit it.

There are others like this that I need to do too so I need to learn how to do it. Not just have someone do it for me.

ALSO as you can see this sheet displays #N/A all over the filled in cells... I would like them to be blank until I enter some pertinent info... I tried this is cell m7 BUT as you can see in m12 it goes back to the N/A

I'm trying to compare 2 worksheets with the same headers(NAME, ADDRESS, CONTACT NO...). What codes should I use that when there is a duplicated row in worksheet A and worksheet B, it will be deleted and when there are 2 names with different addresses and/or contact no, the whole row in file A will be obtained. Output should also be in another worksheet. It goes like this.

worksheet A NAME ADDRESS CONTACT NO JOE ABC 123 MIL XYZ 567 NIK LMN 234 NED QRS 456

[Code]...

So the output should be:

worksheet C NAME ADDRESS CONTACT NO JOE ABC 123 MIL XYZ 567 NIK LMN 234 NED QRS 456 JIM JKL 345 SAM FGH 789

I've got results in row 3 - 16 386 and sometimes these results are exactly the same in some rows. What I now would need is row AB to display only one of each result and row AH to display how many percentages of the time this particular result appears.

I have a count for each site for certain cloumn headers. But i want to collate these so that if there is a 1 in the column the it will output it with the column header. But there are 10 column headers and I would like to get a result that has all the columns with 1 in.

eg: a b c d e f g h i j k l m n o p q (Organic Suites) (Inorganic Suites) sitea 1 0 1 0 1 1 0 1 0 1 1 1 0 0 0 0 (O1 O3 O5 O6 O8 OS) (I1 I2)

I have a formula in A1 that I would like to execute from A2. I want the A1 to display the formula (so no "="), but I would like cell A2 to execute the formula in A1.

If A1 contains: "SUM(1+2)", how can I get A2 to display "3" without reproducing the formula?

A1: SUM(1+2) A2: ????

I suppose I'm looking for something like this: A2: ==A1 But, of course, that doesn't work.

If I do this it gets close: A2: ="="&A1

But that returns "=SUM(1+2)" instead of executing the formula.

I am trying to write a formula using If statement to output the result "True".

I have 4 columns (P3, T3, AD3, AK3) that store a value of either "Yes" or "No", I want to check the column if they are equal to "Yes". I have written a formula but it only works for 1 column at the minute, i not sure how to add the other columns into the formula:

I am using an input box to enter the value of column D. After the value of column D is entered, I want a message box that displays the corresponding data in column A and B. with the vba coding?

creating a .Find code to search a range on a sheet and then display each result seperately in a msgbox. An inputbox will be the value .find searches the range for.

the msgbox needs to be a vbyesno

VB: 'SEARCH CODE Dim myItem As String, myRNG As Range, NewLoc As String Dim Found As Range [code].....

I am using the below formula to find the latest date (column N) based on fund (column G) and Vendor (column O) reference. How can I find (column I) where the balance of that payment is? I know there are formulas like INDIRECT RC[-1] but how to add them to my formula.

Hopefully you will be able to help again. Is it possible to do a vlookup that references data on other tabs within the worksheet so that the result of the formula is in the cell not the formula.

So if my vlookup was =vlookup(a2,$a$1:$b$12,3,0) and the result was john smith i want just john smith in the cell. I know about copy and paste values but i was looking for a more automatic way. One that doesn't need intervention.

i have a routine which loops through a range looking for past dates and when it finds one display the result in a message box in my testbook i only use 25 rows but it gets annoying having to click ok for every find....is it possible to collect all results and display them in the message box at one time?

Private Sub Workbook_Open() Dim Mycell Dim Rng Set Rng = Sheets("Sheet1").Range("B1:B25") For Each Mycell In Rng If Mycell.Value < Date Then MsgBox Mycell.Offset(0, -1).Value & " Is Overdue By " & Date - Mycell.Value & " Days, Take Action Now!", vbOKOnly, "Tasks Overdue" End If Next Mycell End Sub

I have a quick question regarding this simple code thats been drviing me nuts. There x distinct pieces of Data in the range speciifed, but when i run this code, the reply posted in cell H1 is 1, instead of x.

Eventually the code will be built to check if the result is odd or even and then add an entry into the first blank cell if the result is odd.

I am trying to find a way to display text that is the product of a concatenate function in a defined cell, but not to have the function itself in that cell. Basically, I want to have the below function in cell A1. I want to add a command to it to take the result and display it in cell A2.

The reason for this is that I need the cell to be selectable (it is generating a file name that needs to be selected and copied), but I don't want the code behind it to be seen. I can't find a way to make the cell selectable AND hide the formula from being seen when the cell is selected. This is because our people keep copying the formula rather than the resulting text.

I was hoping for something like a DISPLAYIN(target) function, but it doesn't seem to exist.

Excel 2003. I have been struggling for an hour how to hide a number to text macro in a way that only macro result is displayed in a cell.

(I have one 2-3 years old xls, where I have managed with task, but now can't figure out how and how to unhide the macro Can it be password protected somehow?

I entered a simple formula in a cell =B14*B16 but it won't calculate. The cell only displays the formula and not the result. tell me what I did wrong. I've attached a sample.

I am trying to display the result of a custom VBA function as a label on a userform. The function is called and takes arguments from three text boxes on the userform. I attached it to the exit parameter. (This may be part of the problem; I'm not sure).

There seem to be two problems, first all the text boxes don't always contain data, but because the arguments are not optional, I get a type mismatch error when the code runs (I tried switching some of them to optional, but it didn't help as you can see from my 'commented code).

The other problem is that even when all the arguments seem to be met (i.e. the text boxes all have data), I still get a compile error that the argument is not optional. This only happens if I try and pass the result to some aspect of the userform. As you can see from the last coded line in the custom function, if I assign it to a range on the worksheet, it functions fine.

Private Sub txtStartDate_Exit(ByVal Cancel As MSForms.ReturnBoolean) Dim StartDate As Date Dim EndDate As Date If IsDate(Me.txtStartDate.Value) Then StartDate = Me.txtStartDate.Value Me.txtStartDate.Value = Format(StartDate, "m/d/yyyy") Else: MsgBox "Please enter a date" End If.............

I want to make a formula based on 2 times ex: 10:07:00 and 10:09:00. This formula should display "intime" if the diference between both is under 20 minutes, "outime" if the diference is above 20 minutes and it should display "error" if the time is under 0 minutes (this will only happen when someone makes a mistake typing in the time. For example 10:37:00 and 10:36:00)

Currently I am working on a data entry form for CRM database using Excel. Now i am stuck at filtering and displaying the data from the spread sheet to the user form.

There are three text boxes to key in the filter criteria and a button which will filter the data from the spreadsheet based on the criteria in the three text boxes. Then the whole row where the filtered data resides will be displayed on text boxes on the user form.
