Optimizing Coding
Jun 3, 2008
I have made this vba to go out and look at 2 different locations which contain simular folder names.
The script then writes the folder names in Column A, followed by the Size of both the folders from the 2 locations. The script is comparing the second location folder name to what the first process put in Column A so the folder names will be aligned with the file sizes. It is also converting the file sizes from bytes to the most appropriate one.
The problem I am having here, is once I put the second part in for the second folder, the script is either taking forver (More than an hour) or is freezing. So I am not sure if I put it in a loop somewhere or what exactly is happening. I am just wondering if I can get some help troubleshooting and optimizing this code....

I created an Excel tool into which really thousands of records are based on weighted averages calculations. And discovered Excel struggling in term of permormance.
The issue is: the user needs to uploads a couple of times in a day new data for further analysis, and the only way to make the Excel spreadsheat humanely usable (performance) was to calculate everything upfront.
To optimize the tool performance, I had to:
- First I made all weighted average calculations upfront when data is uploaded the first time. Leaving formulas in the tool was not viable, since this tool run live analysis, every click would have been a pain of 30 sec at best to re-calculate new conditions,
- Second optimization was to not leave formulas into columns > as soon as a calculation is done, the macro copy/paste values
The formula I chose is sumproduct based weighted averages..
Here is my question:
1. Does it exits specific formulas in Excel to handle nicely large amount of weighted averages to calculate ?
2. Should I consider to use an external application (an Access table, SQL or whatever) to perform those weighted average calculations quickly/quicker.

I'm trying to find definitions/commands to make excel find the best combinations of several defined scopes and restrictions to make an output number as high as possible.
This is by using a combination of several different equations, maybe excel has a magic trick for all the variables and formulas.

I've attached a file that is the result of a product forecast.
What I'd like to do is minutely adjust the data in B4:K12 so that the totals shown in blue colour on Row 15 and Column O are respected.

Here is exactly what was described:
A good place to start is to add some "timer code" in your macro. Add a small routine that saves a time value, and another routine that compares that saved value to the current time and displays the difference. At the beginning of a section of code you want to analyze, you call the first routine (which saves the start time), and then at the end of the section of code you call the second routine. In that way, you can determine which portions of your code are taking the longest time to execute. These are the code sections you then focus on, so you can figure out what they are doing that is taking so long.
This sounds like a great tool for optimization...

The idea is that I start out with a number of XML files, which I'm trying to manipulate to calculate descriptives and make graphs of in Excel.
So I've made a large "script" in VBA to accomplish these goals, which works, but I'm trying to optimize the code step by step.The overall process that I want to achieve, consists of :
1) Open the XML in Excel as an XML Table
2) Use the filters in the top row of that XML Table to select the data that I want to use
3) The resulting selection consists of data in 6 columns of which I only wish to select column 2, 5 and 6
4) I only wish to select the data in the table of column 2, 5 and 6 (without the header and only the cells in the table) and copy
5) Last step is to paste this data in Sheet "Calculations"
The step I'm working on right now, is step 3-4. My current code is: [Code] ......
This does the job, but I'm trying to optimize it, since I'm handling tons of XML files and I'm performing this copy function a number of times per XML file.
This copies the data of all the columns in the table for the cases that meet the selected criteria, but I'd like to make an even stricter selection of only column 2, 5 and 6 to not waste space and processing power.
So I tried to select the data from the 3 columns and combine them with the Union function, to copy them as one array to the sheet Calculations.
Optimized a similar VBA code to: [Code] ........
But I'm having issues with getting the right selection method and when I run the macro, I get the error message that the Copy and Paste area aren't the same size.
I tried to alter my initial code to something in the line of : [Code] ..........
But I get error messages 1004 : Method 'Range' of Object '_Global' failed.
I've also tried [Code] ........
But this seems to select the whole column, including the header and tons of rows even after the table ended.

Operating System: Windows XP, Excel version: 2003
Aim: To create a Macro to hide all rows where the date in column D is before today. Column D has about 600 rows.
Current solution:
Code:
Sub Hide_Old2()
'Worksheet name
With Worksheets("Schedule")
'set start of date range
Set rngStart = .Range("D2")
'find end of date range
[Code] .....
The problem with this solution is its speed, or lack thereof. It causes the screen to hang and flicker while it cylces through. Is there some way to create a range based on the date and hide the range? or another solution?
Note: Autofilter is not an option, as the spreadsheet with the dates needs to be kept simple for other stakholders and the macro is being run from another sheet.

My spreadsheet calculates the date on a daily basis.
I would like to create a code in my spreadsheet which uses the year and month in question.
First, 2006 is is designated as a "3"
2007 "4"
2008 "5"
2009 "6" etc
Don't worry about anything prior to 2006.
Next, the months are represented by single digits. So, January = 1, February = 2, March = 3, April =4, etc. September is 9, and October = 10 but all the numbers over 9 have to be reduced to a single digit, so October = 1+0=1, November =1+1= 2, December =1+2= 3.
Now, the formula for the Month is:
Year + current Month
So, May 2007 = 4 + 5 = 9
June 2007 = 4 + 6 = 10 = 1
July 2007 = 4 + 7 = 11 = 2,
January 2008 = 5 + 1 = 6, etc

Is there a way of coding a macro in VBA that allows you, with one macro, to enter text in one cell and at the same time enter a value to the cell on it's right?
I don't want to name the cells, but I wondered if you could add to the code a piece of code that basically said "Select the cell to this cell's right and add the value x".

I have a drop down box with the 10 different shifts we run here at my work. Ie - Daytime (0700-1500), Nightime (1500-2300) etc. I have these on a drop box as stated earlier (Cell 6) - and want to code a selection from within the box, to effect Cell 7 with the approriate hours worked depending on what I selected in Cell 6.

I am looking to create coding that once stock gets to a particular level a text box pops up to alert the user that more stock needs to be ordered and ideally I would like once the user selects ok for it to take them directly to the appropriate email template.
However, I don't want the text box to come up while we are waiting on the stock to be ordered.
i.e our current minimum stock level before placing our next order is 10,000 units. Order is placed and can be received within 10 - 14 days. During this time our 10,000 units will be used but I don't want an alert to pop up to remind the user to place an order as this action will already have been carried out.

I am trying to figure out how to run a macro for 1 particular workbook in an excel spreadsheet. I don't want it run on any of the other workbooks in that file, just the 1. I can't use conditional formatting because I need more than 3 values (if statements).
This is what one example of data in a cell and below is the color I'd like it to turn when I run the macro:
T: 6/1/07
A: 6/8/07
Anything that has a A: (which means an actual date it happened) I'd like the cell to turn blue. If there is an RT: (which means revised target) I'd like the cell to turn red which means it missed it's target date, and has been revised. If it has a TBD I'd like the cell to turn pink (or yellow or any color really). All other cells are just white. I don't know where to find the color codes in excel as well. Other samples of what cells look like are below.
Here is another example:
T: TBD
And final example:
T: 6/4/07
RT: 6/15/07

I am trying to learn how to use it in some of my Excel application. I am just wondering if someone would be willing to help what I am thinking would be a short string of code.
What I have is a list of files that I have compiled along with a name and description in cells B3 and C3 respectively. In cell E3 what I have is the path to that file which is linked so that I can click on it to access the file. Is there any way that I can write some kind of simple code to look up the last modified date of that file whose path is specifed and place it in cell D3.

Is it possible to select a number of cells that are say yellow when blank but once someone type "N" or "No", they change to blue and if "Y" or "Yes" they change to green. I tried conditional formatting but it does not change the blank range to yellow until I have entered something into it.

In each VBA book I've read the authors will write their code like this:
nStart = UBound(GenArray1)
nEnd = UBound(GenArray2)
Redim preserve NewArray(nStart To nEnd)
Instead of the less line method of:
Redim preserve NewArray(UBound(GenArray1) To UBound(GenArray2))

I have a spreadsheet with cells containing different names. I want all of the cells containing the word Volitility to be colored one color, all of the cells with the word Momentum colored another color, and so on. I have more than three names so I cannot use conditional formatting. Attached is a workbook that has the uncolored cells in worksheet 1 and an example of what I want it to end up looking like in worksheet 2.
