Friction Loss Calculator For Fire Hose
Apr 17, 2008
I am attempting to create a friction loss calculator for fire hose, I am using a known formula that calculates the loss based on volume and diameter for pipe. the difference that I have with fire hose in lieu of pipe is that the hose diameter changes with the pressure drop.
I have 3 variables that i input, pressure, beginning diameter and length. however
as the water flows through the line the pressure changes in turn the diameter changes, I would like to set up my spreadsheet so that the initial variables inputed yield the correct diameter, and then reference back to the initial equation and recalculate based on the yeilded diameter, and recalculates,
I can determine the friction loss at 1 foot, in turn determine the diameter at 2 foot, but I wish the spreadsheet to work the calculation over the entire length.

Is it possible have code in an addin that fires when, X happens in any workbook?
For example,
Any time a user tries to print a worksheet a message box pops up asking, "are you sure you want to print that"

I wish to fire one of 2 different macros, depending on the Target.Text value.
If the Target cell (in a named range) is blank then one macro fires, If the cell has text then another macro fires.
this is what I have
If Target.Column = 7 And Target.Row > 7 And Target.Text <> "" Then ViewPicture Target
Else
If Not Target.Column = 7 And Target.Row > 7 And Target.Text <> "" Then GetPicture Target
End If
I can only get the first if statement to fire, I get an "ELSE IF" compile error on the second "IF"statement.
It is nested in the
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Page
and I would like to get it to work with Named Range's, but not enough understanding yet.

I have an Excel 2007 workbook with over a dozen user forms and plenty of code that I have mainly obtained from the web and tweaked to suit my needs. I am a novice with VBA, so not really up to writing anything but quite simple code.
My issue is I have some code set to fire on Workbook_Open that will save a versioned copy of the workbook, to the same network folder that the original resides in, with an incrementally increasing file name. the file is stored on a network, but access should not be an issue as I have full access and have no problem saving to this folder, also the event works fine up until I shut down Excel. I have also tried saving to My Documents to avoid the network issue, same result, worked fine as long as Excel is not closed, fails if I do.
It all works fine until I close down excel completely and re-open, where it then fails to work. There are other events happening in the same Workbook_Open sub that still work fine each time, so the sub is firing on open, but this one event fails. I get no error message at all, just no new file copy created.
The workbook is essentially doing the job of an Access database (I know even less about Access), I have a user form as a main menu and various other forms for various data entry and reporting tasks. I am exiting the w/book via a cmd button on the main menu (I've deliberately restricted users control, as many are not very pc literate). I have conducted numerous trials consisting of running the code from the VBA window, closing w/book via cmd button WITHOUT accepting the std save option and re-opening from Explorer window, closing w/book via cmd button WITH accepting the std save option and re-opening via Explorer and all worked perfectly over many sample runs. But when I closed Excel totally (Not just the w/book), created a desktop shortcut and opened from there, that line of code just doesn't seem to do anything, no error or hang or anything. The only way I can get it to function again, is to re-save the w/book (As either a new file with code edited to suit, or overwrite the original), and keep Excel open whilst only closing this w/book. It then functions perfectly again on opening.
I have enclosed below the Workbook_Open sub and some other subs that append to a user log on opening, these work fine all the time. I enclose the others in case they may have some bearing, as they are also fired from the Workbook_Open sub and show no issues at all.
Any suggestions gratefully accepted as I am struggling. As mentioned above, the ONLY part of the Workbook_Open sub that fails is the line "ThisWorkbook.SaveCopyAs newFileName". I have even added "MsgBox "The new FileName is: " & newFileName" immediately after it, and that displays new filename correctly. It seems to me to be hingeing around the SaveCopyAs event, but I don't want to assume that, being the novice I am.

I am having a problem finding the right javascript function(s) to use in my macros. Use Google homepage as an example. The line
.Navigate "javascript:_dlsetp('ss=2')"
will open the page for customizing your Google page. But what is the function you fire on in the macro to execute the general search? I can send text to the search input box, but I can't find the function that runs the search.
Is there some way to quickly identify the function and the correct syntax without having to learn how all the source code in the web page works? Finding the right URLs, links, and input boxes is fairly straight forward. But not the functions.

I have a large file, part of which amongst other things calculates life expectancy from a range of q(x) values (proportion of people that die moving from age (x) to (x+1). Life expectancy is calculated using a user-defined function (below).
My problem is that whenever I run a macro that changes the file, even parts of the file that don't affect the cells using the life function, it jumps into the life function. (An example: copying and pasting values on a different sheet). This is a hassle when stepping through other macros using F8, not to mention the time cost.
Some further possibly necessary information: one macro uses the GoalSeek application to set the target cell that contains the life function
By the way, this didn't use to happen in older versions of a similar file. When running the GoalSeek macro to change target life expectancy it did, but not for any other macro.
Here is the function:
Function life(data As Range)
' Aims to calculate Life expectancy from Qx values
' It assumes first value of Q is Qb, then Q0 to Qmax
Dim Nobs As Integer
Dim j As Integer, i As Integer
Dim q() As Double
Dim L() As Double
Dim T As Double, le As Double
Nobs = data.Rows.Count

very complex spreadsheet for weight & balance calculations. It's to the point where everything works perfectly in Excel 2007, but it must be used primarily with Excel 2003. Discovered that a crashing problem had to do with condtional formatting, that's all been cleared and will soon be fixed, but there's one that I just can't quite figure out.
I'm using the worksheet change event to trigger the update of charts... In this case, it's looking at a particular cell that has data validation on a dropdown as the trigger. Works perfectly in 2007, and if I put a msgbox prompt in to be launched by a change of that cell, it launches. I can put the chart update code in a separate sub and launch it manually every time, but I cannot call it from the worksheet change.
I've included attachments showing what I believe are the relevant bits of code -

I have three cells where a user will input data, in some cases (2T Weld Condition) they will only enter in B12 and C12, but in the case of a 3T weld they will also enter data in the D12 cell. I then use a formula to check for the thinnest material and that is entered into another cell with a formula, B14. I then need to check the value in B14 to verify if it is above zero, but below 0.65 (mm). If it is then I would like to have a message appear on the screen notifying the user that they are outside the acceptable range.
I cannot figure out how to use the information in cell B14 because it is a formula and my code only works with a direct value. The code I am using works if I point to one of the three input cells, B12, C12 or D12. How do I use the information in B14 to work with the code below.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$B$12" Then
If Target.Value < 0.65 Then
Run "MyMacro"
End If
End If
End Sub
MyMacro loads a userform with buttons, etc.

Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Target, Me.Range("R1C1")) Is Nothing Then
'do something
End If
End Sub
Now, that Private Sub works fine if you change the value of R1C1 manually or from another macro.
But if R1C1 is the cell linked to a list box, nothing will happen if you change its value by selecting different items in the list box.

I have a trading system spreadsheet that I am at a loss as to how to calculate the profit and loss.
I was unable to attach a sample of the spreadsheet. I hope this explanation works. If not, I could email it.
Where:
Market position is either 1 or -1
Entry price is the price where the position is reversed.
For example:
H3=1 and I3=100.56, then
H4=-1 and I4=100.88, then
H5=1 and I5=100.53
I need to calculate the profit as follows:
I4 - I3 (because market position of 1 expects the price to go up) and then,
I4 - I5 (because market position of -1 expects the price to go down)
I want to calculate this as a running total to the bottom of the column.
This is the formula I was working with, but it doesn't work:
=IF(OR($J4="",ISERROR(MATCH(-$J4,$J4:$J$55,0)),),"",$J4*(OFFSET($K4,MATCH (-$J4,$J4:$J$55,0)-1,)-$K4))

I have a workbook that contains several worksheets. The 2 important sheets are Imports and Sales.
In reading the MS KB, the help screens and this forum, I found a way to create a pivot table from 2 sheets using Data>Pivot Table>Multiple Consolidation Ranges. While that PT will provide a basic inventory and profit picture, it only allows 4 selects.
When these products are imported there are several SKU's. What gums up the works is there are several vendors for the same SKU's. Each vendor has a different price. The selling price is constant so the profit made on each particular item varies.
I would like to be able to keep track of inventory by vendor as well as profit by vendor.
Using the Consolidation PT does not seem to work.
I also tried making one sheet to hold all the data. i.e. data showing imports and sales. However, each entry is driven by the date. So while item A was received on 1/1/07, it was not sold until 1/2/07. The necessary columns for imports are filled in while the columns for sales remain blank until it is their row entry indicating a particular sale. At which point all the columns regarding Imports are blank. I swear, looking at the data sheet with all those blanks (actually0's) is like looking at a mouth full of broken teeth. The resulting PT is also not attractive.
I can not imagine I am the first person to have this problem. How do others handle figuring inventory and profits when you have two sheets. Are Pivot Tables the wrong solution? What would be better?

How do I track my total weight loss in excel? Here is an example of what I am trying to do.
8/1/2008 228lbs
8/2/2008 225lbs
8/3/2008 223lbs
Total 5lbs
I would like use a formula that would subtract my absolute weight loss total day by day in August. Basically, I want the total "cell" to equate to my total weight loss in August. For Example after 8/3/08 the "total cell" should equate to 5 lbs. What formula do I use to do this?

I have a excel 2000 spreadsheet that has beginning and ending dates for certain services. I'm trying to tease out what our customer base has been doing over time in aggregate- i.e. how many customers subscribing to X in a given month/year.
The only way I've been able to do this in the past has been generating pivot charts of start dates (with 'start mo' and 'start year' busted out) as a positive count (+1), stop dates (with 'stop mo' and 'stop year' busted out) with a negative count (-1), then copying these tables into yet another page where I mash them together to get the 'flow' of our customer base over time and generating charts from there. Needless to say, it seems a whole lot more clunky than it should be, and I'm having a hard time searching the innarwebs for similar examples (even though I'm sure it's been done before). Example:

I currently copy/paste sports data from the web into MS Excel. One of the columns pasted contains "Won-Loss", which appears as '1-0' on the web. However, once the data is pasted, Excel identifies this field as a date and changes the value of '1-0' to 'Jan-'00. I would like to insert a new column and convert the field back to text (i.e. Jan-00 to 1-0). I have attempted several formulas, however no luck as of yet.

I have a # of games played column (Column A), a # of games won column (Column B), and a number of games lost column (Column C).
I'm trying to make it so Column C automatically enters the number when I put in the number in Column B.
Example:
Games Played........Win........Loss
1.........................1...........0
2.........................1...........1
3.........................1...........2
4.........................2...........2
For the fifth game played, if I won it, how do i make the 2 to automatically enter into the loss column when I put in the number 3 in the win column?

I have multiple departments I need to keep track of multiple numbers with. For example, I need to see the cost of payroll for last fiscal year, vs this fiscal year and have excel show that as a gain (bad) or shrink (good).
I need to track sales this FY vs last FY, obviously, a gain is good and shrink is bad.
Finally, I need to track d&d goods this FY vs last FY.
Where I'm getting held up is, for example last year's payroll was 12000 and this year's is 12500 but next months is 11000 this FY vs 13000. How do I get excel to figure out that payroll decreasing is good and not just do simple subtraction or negative addition thereby allowing me to just plug the numbers in and excel figure out if what I'm throwing at the cell is bad or good comparing to last year?
Also, if I could figure out the if/then to show positive numbers green and negative numbers red that would be quite awesome too.

I'm trying to create an excel spreadsheet that keeps track of the highest value from a dynamic series. First a bit of background:
A manufacturer produces widgets made from gold. Therefore in order to quote manufacturing prices, they typically get a live gold price using Excel's web services and if the live price is higher that the last gold price they used, then they update their base price list for gold components. If the live price is lower than the last gold price they used, the last gold price does not change.
I'm trying to produce the above logic in Excel using:
Cell A1: [Excel data connection to pull live Gold price] - no problem here
Cell A2: dynamic 'price' that only updates if cell A1 is higher than cell A2
Cell A2 is where I'm getting stuck. I can't think of how to create a formula that updates cell A2 if cell A1 is higher.

Using a macro I want to paste from the clip board.
I can manually do this by opening the clipboard, selecting the data, which pastes to my specified location.
The macro copies to the clipboard okay, but loses the data that I want to paste because just before pasting I have to clear data which was previously been filtered - I have to do this at this point. The macro bogs down. If I end the macro there, I can manually open the clip board and choose the data I copied from there and paste it that way. I'd like the macro to do this for me.
