Speeding Update Process Of A Database
Jan 15, 2007
Did not want to hijack Jonny's thread about ways in which to update and streamline code to make it run faster. The update speed of my first attempt at a macro is woefully slow - 5 minutes for 2.5K records. I was wondering if some of you more knowledgeable folk could look at my code and make suggestions as to how it could be modified to run faster.
When I ctrl-break out of it I usually end up in a private sub that concatenates columns A & B in Column C (see below). When it resorts the database it must keep triggering this concatenate sub which (I think) is slowing things down.
Concatenate Private Sub:
Option Explicit
Private Sub CommandButton1_Click()
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Or IsEmpty(Target) Then Exit Sub ......................

i'm working on floyd algorithm macro for a project,
problem is, the spreadsheet matrix is huge, it's a 1043 x 1043 spreadsheet
And this is taking wayyy too long, i've been waiting for almost 2 days already..
here's the file :
http://ifile.it/6v2j39f
(You start the macro using "run" command in "input" sheet)
So is there any way to speed it up?
Or if anyone got a supercomputer, could you help me process this? :p
I'm thinking about changing the 10^5 value into infinite value, but i can't find a way to display infinite value..
And here's some reference for Floyd's algorithm,
http://ifile.it/12p5zle
I have tried to split the algorithm to make it process one iteration at a time, but i've been waiting like 2 hours with no result,
and that's for 1 iteration, can't imagine how long it takes for 1043 iterations
You can do this by deleting the.

Basically I want to set up a workbook, which will have a sheet called "Database" and then sheet1.
I want to use sheet1 as a "add to database" sheet, where users will simply dump in some data into sheet1 and the marco will format it so it matches the headers of the data base and then it will add/update the database sheet with the info (and new info if its new) from sheet1.
Here it is in pictures.
This is basically what the database sheet will look like (but much much much more rows of data)
As you can see this is a job database with some columns for POD, Connote, etc.
This is what the update sheet1 will look like when someone dumps some new data in (I can easily write a macro that formats it to match the database)
So basically I want the VBA to merge this sheet1 data into the database sheet, as you can see, there is simply a few 1's added to various columns for "Car Dudes" and "Robin Manufactures" but "Jimmys Lollies" row is completely new and not in the database.
So the marco would basically match up either the Job number or the HB number of the rows in sheet1 and if there is a match in the database sheet it will update the cells data, and if there is no match it will add the row to the database sheet.
The issue is the data in sheet1 might not be fully complete all the time, it might only have a job number and not a HB number, it might not have a client name or whatever. Basically the data users dump into sheet1 will come from many different reports, many different sources, what I'm trying to do is essentially merge all this data into a common formatted database sheet, for further working.
So in a nut shell, a macro to:
1. Match Job/HB numbers in sheet1 with rows already in database sheet and update row accordingly with any new data.
2. Add any new Job/HB rows from sheet1 into database.

I am Working on a Query to Update Record in the Database if Exists Otherwise Insert. I have 2 tables in the database Receipt table and Inventory Account Table.
For Receipt Table there is Form which is used to Insert Data into the Receipt Table(SQL TABLE). Behind the Button Click Event with the Receipt Table Insertion Query I Write a Select Query to Get data from Inventory Account Table Group By Part Number and Location in a recordset.
Code:
objmyrecordset.Open "select [Part Number],sum([Quantity Received]) as TotalQuantity,[Move From] from [5_PO_RECEIPT_TABLE_DATABASE] group by [Part Number],[Move From] ", objMyConn, adOpenStatic
objmyrecordset.MoveFirst
Do
strSQL = "select Count(*) from [Inventory_Account_Move_Table] where [Part Number] = '" & objmyrecordset![Part Number] & "' and [Location]= '" & objmyrecordset![Move From] & "';"
[Code] .......
I used the Above Code to Complete my task. The Problem is It is Adding the Correct Values into the Inventory Account Table But It is Not Updating the Previous Records. it sum all the Values in Receipt Table based on Part Number and Location but it insert this record in New Line. I want it to Update the Previous record for same part Number and Location.

I have database that needs to be updated automatically. Thus far, I have written a macro that will take out and add all necessary data from a file I open, however I would like to write a macro that will find the most recent files and use them to update the database. I would need the macro to 1) Find the folder name that corresponds to the part number in the database, and open that folder, 2) find the most recent file addition to the folder 3) open that file and run the macro that I've already written.

I would like not to have to update the source data for the pivot table in my database. I've read that you can solve this by using a Dynamic Named Range and using that as the source for the pivot table. That way the pivot table will expand as new data is added to the database. The formula I used to create the DNR is:

In an Excel sheet i have set up a link to an Access database query (select query) using the Import External Data method. The data is store sales by week, arranged in a pivot table layout (stores as rows, weeks as columns). As time goes by, the database will be updated for new weeks sales, and i would like to refresh the data and the new weeks automatically appear in the Excel sheet, in subsequent columns.
At the moment, the only way i can seem to get this to work is to open up the link in MSQuery and manually select the new weeks from the Access query. i have set the parameters to overwrite cells with new data rather than insert new data. i'm sure there is a way to do this, as it feels like it would be a common thing to want, but i can't seem to find an answer anywhere!

I have a workbook with a database of 15 different products. We receive information with current prices for each of the 15 products on a weekly basis. This info comes in one single worksheet. I have created a different file with one worksheet for each product to track price behavior over time. I need to update these database everytime I get a new report. What I was trying to do is to develop a Macro to copy the data from a "Master" worksheet that includes all 15 products info to the respective worksheet for each product. Information is sorted in columns having the most recent date in the lowest column. I would need the Macro to copy the new data below the last price for each product. I would copy the data into the "MAster" worksheet, then run the Macro who would copy each row and paste it in its respective worksheet in the row rightafter the previous one.

I've been working on the following code and need to find a way to speed it up.
The premise is that I have a list of columns (From C2 to potentially EH and beyond) and these columns will contain the values Y, N, end or nothing. I'm looking for the quickest way to zap along the columns and delete all that have an N and to stop when end or "" is reached.
There are 2 versions as I'm not sure which one is best ...
Range("B2").Select
LastColumn = Range("A1").End(xlToRight).Offset(, 1).Column
For k = 2 To LastColumn
ActiveCell.Offset(0, 1).Select ' right 1
If ActiveCell.Value = "Y" Then Next k
End If
If ActiveCell.Value = "N" Then
ActiveCell.EntireColumn.Delete 'If employee has no sickness then delete column
ActiveCell.Offset(0, -1).Select
End If
If ActiveCell.Value = "end" Then Exit For
If ActiveCell.Value = "" Then Exit For
Next k
or a longer version
StripSickness:
Range("B2").Select
ActiveCell.Offset(0, 1).Select ' right 1
PrintView = ActiveCell.Value 'Y/N whether employee has data
If PrintView = "Y" Then GoTo StripSickness
If PrintView = "N" Then GoTo NotNeeded
If PrintView = "End" Then GoTo Complete 'last column shows "end"
If PrintView = "" Then GoTo Complete
NotNeeded:
ActiveCell.EntireColumn.Delete
ActiveCell.Offset(0, -1).Select
GoTo StripSickness 'once employee is deleted, go back to stripsickness process
Complete:
Range("a1").Select

This may be a long shot, but I've been working on a macro today which runs a few Vlookups, does some copying and pasting and some re-aligning....basically nothing too complicated. The Vlookup is looking through approx 45,000 records and returning about 200 - 300 on average, this info returned is company name, address, contact info etc etc.
This macro is taking a ludicrously long time to run, I've checked through and removed any coding that I think is unnecessary without altering the final outcome of the macro.
It still takes ages. Has anyone got any ideas why this may be, or any tips of speeding it up?
I have a brand new computer, dual core processor, 2 gigs of ram etc so it shouldn't be performance of the machine slowing it down, and I ran it with the least applications open that I can (I'm at work so can't close everything, but none of the other applications are memory hogs or anything). I'm running on Office 2003 on Windows XP.

I am running a rather large simmulation where I have 12 for loops with each running between 0 and 100% with variable steps and the where the sum of the 12 variables has to sum to 100% and sometimes combinations of the sums of a few of the 12 have to sum up to specific values. That part works, now I am trying to get this to run faster.
Question:
Is there a different design that might be able to run this process more efficiently?
If not, is there a way to speed up the process by letting the computer know that all these variables are between 0 and 1 (or 100%) and that I only need 3 digits after the decimal if the value is in % form?
(the only problem with the rounding or cutting off the decimals at the end that I can think of is that it will only speed up the process a bit but will also make the summing upto 100% or any other value difficult)

I've been working on cleaning up some code that copies particular information from one sheet (as the original must remain unedited) and then edits out irrelivant information.
However I've noticed that my "before" code moves far faster than my "after" code, which is odd considering that I've cleaned out a lot of excess code and the end results are the same.
I attach an example of my old fast code and my new slow code - can anyone advise where I have gone wrong ? Run the fast code first and then the slow one - you'll see the difference!

I need help with speeding up my macro. I have been building this using alot of the recorder and the maco is just horribly sluggish. I don't know if it is possible, but it seems like it is. I need the macro to obviously work the same way. The way it has been recorded, the order of operation is important. But if any one knows how to do this better it would be a huge help. The slowest part is during the insertion of the formulas into col. J,K,&L takes like over 7min -- Macro does work perfect though.

first, id like to thank the board for the help on setting up an array or ranges.
ive been able to get my code to work but its painfully slow...if anyone had any recommendations on speeding it up would appreciate it...i was playing around with using formulaarray instead of writing and reading the data on each loop but cant get it to work...and i'm not really even sure thats the right way to go.
i copied the entire code below...what i was doing was taking 8 time series and looping thru each one to calculate some basic statistics...i ran the function EDFlyRateFromPrice to calculate another series of data which i then run the standardize, max and min functions on.

This code is pretty slow if most rows have to be hidden. I'm certain there is a faster way to do this but I'm not seeing it.
What am I doing with
For each row from 12 to 236 I'm looking to see if there is data in any cell in columns A:F, H, & J. If not, I hide the row. I'm starting at row 236 and working up to 12 continuing to hide rows until I find data or I reach row 11. As soon as any row has data or row 11 is reached the the procedure ends leaving all remaining rows visible ...

Ive found a few ways to speed up the macro in my workbook thats taking about 40 minutes to process usually.
One way - Press Escape and it goes about twice as fast! - Wy does it do this?
Another way - Inserting these lines into the code -
Application.Calculation = xlCalculationManual
Application.Calculation = xlCalculationAutomatic

I am putting together a workbook which calculates a rota for 5 days that shows overall headcounts every 15mins.
It currently has 12672 cells containing SUMIFS.
But this takes a very long time to calculate.
Is there a faster / more efficient way for me to approach this task?
Can I attach the workbook so you can see what I mean?

Delete rows where column A and B are duplicated.
However, this runs extremely slow. I had to stop it after about 10 min, as it only got to about row 1000 of 20,000.
Sub Delete_Dupes()
Dim rw1 As Long: rw1 = 1
Dim rwx As Long: rwx = rw1
Dim stepx As Integer
Dim co1 As Integer: co1 = 1
Dim co2 As Integer: co2 = 2
Dim bool1 As Boolean
Dim bool2 As Boolean
Dim bool As Boolean
Dim count As Integer
count = 0
Do Until Cells(rwx, co1) = ""
stepx = 1
If rwx > rw1 Then
On Error GoTo NewCrit
bool1 = IsError(Application.WorksheetFunction.Match(Cells(rwx, co1), Range(Cells(rw1, co1), Cells(rwx - 1, co1)), 0))
bool2 = IsError(Application.WorksheetFunction.Match(Cells(rwx, co2), Range(Cells(rw1, co2), Cells(rwx - 1, co2)), 0)).................

1. I need to paste data that is copied from an internet window into sheet1 without selecting the cell so that I can continue working on a data in sheet5. The macro prevents me from editing sheet5 in an orderly fashion because when it goes to paste the data into sheet1 it selects the cell in sheet1 interupting what I am trying to manually do with the data in sheet5. How to paste data into a cell withou selecting the cell so that my program stops interupting what I am doing in a different sheet?
2. My macro is meant for real-time defect monitoring in a production facility. The macro opens an IE window that contains the defect occurences, copies the data, pastes it in sheet 1 then sheets2 and 3 analyze the data, closes the IE window, and then waits for a time period before repeating the process. This macro is so slow though that it is hard to work on this file while the macro is running. How to run the macro in the background and speed it up so that I can continue working on Sheet5 of the file while the macro repeats itself over and over again? Here is my code.
The variable website is determined by earlier parts of the code that direct the macro to a specific network website.
Sub Half_Hour_Data
1
'Open Internet Window and Navigate to Website
Set myIE = CreateObject("InternetExplorer.Application")
myIE.Navigate Website
myIE.Visible = True
Application.Wait Now + TimeSerial(0, 0, 10) needed to wait until the page loads
[code]....
Is there a way to speed up the macro by removing the timeserials and just telling it to continue when the task is complete. Then run the whole thing in the background so I can work on another sheet while this program runs?

I am currently trying to create a database of products for my company. For each product I would like to include an image associated with it. I then want to have on another sheet a place where the user will click an error and be able to cycle through the products. As tehy cycle the associated image will pop up.
What I need to understand is after importing the image into excel, how do I associate that image to a cell so I can reference it in another sheet of the database. I am not concerned with how large the database will get, my pictures are quite small.

I need the to sum the values of database 1 if the second database is >= 20. So the value I would expect on this example would be 900.

I need to print a worksheet. The sheet has rows of a specific height (45) and data in one cell grows - adding comments/notes with date attached so that last one entered is displayed, the rest get shoved down.
I need to sometimes print out the sheet. However, I want to have all the notes shown so would like to (1) autofit all rows, (2) print the sheet and then (3) put all rows back to row height of 45. All this I would LIKE to have done by "trapping" the print button on the normal Print area
I have attached some code, but the sheet (1) does not print at all, (2) the code is sometimes executed twice (in debug mode followed it) and (3) sometimes does not set the row height properly either at autofit or static height.

Dont know if this is possible. I have a spreadsheet where cell A1 contains a value which is not fixed and can change daily, the value can increase and decrease. At present at each month-end I manually record the position of cell A1 at month end in cells C1 through C12 repsenting the 12 months of the year.
Example:
A1 @ 31/01/07 = 50 therefore cell C1 = 50
A1 @ 28/02/07 = 45 therefore cell C2 = 45
and so on for 12 months
what I would like to do is automate this process to automatically capture the value at month end into cells "c" and once captured, the figure to remain absolute for that cell/month and to ignore changes in Cell A1 that may subsequently occur.
Could this be done by date formula?

I need to know if it's possible to log the process of a series of macros
either to txt file or to a Sheet, (either way won't matter but txt file would be perfect)
For example:
Sub MyMacro1 ()
code
End Sub
Sub MyMacro2 ()
code
End Sub
If this process was logged, then the log file would look something like:
Date Time : Sub MyMacro1
Date Time : End Sub
Date Time : Sub MyMacro2
Date Time : End Sub
But it would be a in text just like a log file.
Is this possible with Excel ?
The reason is because my Workbook is huge and I am forever tweaking and adjusting or fixing and I require reference points.
