I have declared a number of string variables named "hlpYear1", "hlpYear2" etc in the 'Worksheet_SelectionChange' function. "hlpYear1" contains the appropriate text to display if the selected language is English, "hlpYear2" is for French and so on. I was hoping that I would be able to use VBA to display the appropriate text by way of a 'For..Next' statement along the following lines:

First I have a excel with a selection of customers:
Column A = customer id
Column B = customer name
...
this excel contains about 500 premium customers
Secondly, on an external server I have a database with the details (adress, phonenumber, ...) of about 100.000 customers
Now I would like to display the details from the database into the existing excel. For that I was about to write a sql-query to copy the data I need to have into the excel (sheet2) to access it from sheet 1 with vlookup (based on the customer id).
But the large amount of data makes excel to work very slowly and it is impossible to keep on working like that. So now I was looking for a way to create a selective sql-statement.
Something like this:
select details from db
where customerid in (all the customer id's mentioned in sheet 1)
without writing all customer id's manually
I have created a log file for work which records jobs processed. Additional code has just been added to retrieve job information data from a statistical process control program. This works fine however the spc program outputs the Ohmic value as ohms which I need to convert into alphanumeric format. For example: job value is 24K4, spc outputs as 24400 which I need to convert to 24K4. The Ohmic values range from mOhms to gOhms. Examples below.
0.003 = R003
0.025 = R025
0.150 = R15
1.0 = 1R0
15 = 15R
3600 = 3K6
1700000 = 1M7
220000000 = 220M
1000000000 = 1G0
Bearing in mind that the above are just examples of possible values, is it possible to convert numeric values to an alphanumeric format similar to those show above using VBA? You may ask why I need to convert. The log file allows manual input of job information where the value is entered in alphanumeric format. It also contains a search form which displays results allowing the user to see if a job has been processed. Obviously it is easier for the user if the job value is displayed as alphanumeric.
On a work sheet I have 20 columns that may or may not have data in it. In the 21 column I want to have a sum "of the values" in the other columns. Problem is the data is in this form i.e. 6 01/17/07 smr or 15 1/19/07 gtw or 24 01/21/07.
To clarify each cell will have a value of a number from 1 to 99 followed by 2 spaces. Then it can have 2 more spaces and an id tag or just finish with the date.
So, from the example above in column 21 I would have a current value of 45 and it could change if more values were added.
Note values are generated from a macro. It may be possible to change the macro so that a comma or such may be used to seperate the different "values / data types"
I need to automatically populate a column with an alphanumeric MFR0001 to MFR9999 and am currently using the formula below to add 1 to the start point (A1)...
A1=MFR0001
Formula in A2 =LEFT(C1,3)&(RIGHT(C1,4)+1)
This works perfectly if I start at MFR1000, but breaks and drops the 000 if I use it on the number I need to start with (MFR0001).
I have Column A sample below:
Column A
Row 1 WG32127
Row 2 WFH3040 / 3920
Row 3 WFBF3709/3919
Row 4 WG32156/3915, 3911, 3920
Row 5 WG32148129/3915, 2922
I'm trying to use the Left Function to get only the Alpha-Numeric codes only. I'm having the following problems.
1) The alpha-numeric codes are not a standard number of characters (they can vary anywhere from 4 to 10).
2) In some cases the alpha-numeric codes are alone in the column
3) In other cases they are with other numbers with back slashes separating them
4) In the cases where there are back slashes there are spaces, commas and other numbers as well.
Is there a way to use the Left Function to retrieve only Alpha-numeric codes only.
I am wondering if you can sum the numeric parts of a range of cells containing alphanumeric values. Here is an example:
values to sum: 500, a20, ab30
expected results: 500 + 20 + 30 = 550.
In this project, the number of values to sum is large and I do not wish to use long formulas to extract the numeric part of each cell within the range. I am also forbidden to use up extra cells as an intermediate working out. Can you help?
Any code that can extract the alpha numeric values from sample spreadsheet below?
Where in col A "SCn" is extracted (or copied) and then pasted in col H?
n = 1 to 99
That is - from this:
A
B
C
D
E
F
G
H
I
J
K
L
[Code] .........
To this:
A
B
C
D
E
F
G
H
I
J
K
L
[Code] ......
There are thousands of rows to extract the alpha numeric values from.
I have a data set of students results and I have been using countif to pickup similar grades eg, C1, C2 and C3 all as C. However I need to subtotal filter against teachers and the sumproduct won't let me use C* as a wildcard to pick up the three types of C. How I can subtoal countif multiple criteria.
View 3 Replies View RelatedI have two columns of data: 1 column can be possibly anything, either numeric, alphanumeric, or alpha only (VINS or vehicle numbers). The adjacent column are four different types of vehicles. I've tried concatentating the two to try and count the unique combinations (a truck maybe used more than once during the day), which I can get unique values, but not unique values for each type. Also, the range sizes are variable, but no more that 65 rows.
An example:
5CZ975 Van
25RW04 Straight
5CZ975 Van
ZJ6026 Van
So, the result I am after is 2 vans, 1 straight truck
I found an array in a another post, but it is not working properly (see cell F7 in the attached):

I have 2 columns i want to find out which items match in each column and put the matching value in column c. I have tried Vlookup and continue to get an N/A .. I tried countif and I get either an N/A or a value error. I have tried turning the cells into text but that is not working either..
column A has about 1700 rows and column B has about 4000
MOST CELLS ARE 6-7 VARIABLES.. satrting with either 01, 02, 03 with 4-5 letters following or have a 6 digit number or 6 letter value.
I noticed that sometimes if I stop a macro midway (completely stop, not just pause), and then re-run it from the beginning, my variables will still hold the value they were last set to right before i stopped the macro. But sometimes, this doesn't happen - the variables reset.
I'm wondering what defines how long the variable's value are held for? I'm considering writing a macro that can hold variables so that even after the macro is finished, the user can re-run and the variables will still be available. This is useful mostly for text boxes in userforms that will probably have the same values the next time the user runs, but the user can still change them if he wants.
I have four variables a1, a2, cr and s in the macro below.
Code:
Public Const cr As Long = 4
Sub Mode5()
'4 are the constants you can vary to test different scenarios
Const a1 As Single = 0.1
Const a2 As Single = 0.4
Const s As Single = 3
It is easier if think of these variables in this format (a1, b1, cr, s).
So taking the code above as an example they can be written as (0.1, 0.4, 4, 3).
Ultimately I would like to try different combinations of these values to get a desired outcome. Currently I change the values manually each time.
Variable a can range from 0.1 - 2.5 (25 numbers)
Variable b can range from 0.1 - 2.5 (25 numbers)
Variable s can range from 1 - 10 (10 numbers)
Variable s can range from 1 -10 (10 numbers)
write some code to iterate through different combinations of these variables. I presume it would be some sort of loop which increments each variable a certain amount each time until the max value is reached.
For example the first combination would be (0.1, 0.1, 1, 0.1) and the next would be (0.2, 0.1, 1, 0.1) and the next (0.3, 0.1, 1, 0.1) etc and the last one would be (2.5, 2.5, 10, 10).
Altogether there can be 25 x 25 x 10 x 10 = 62,500 combinations.
I have a spreadsheet where in the past we have used a turnover period (always 12 yrs) as our constant to calculate our average factors. For example we use formulas to calculate up to 12 years and the we just restart at year 13- providing that one of the formulas does not return a 0 value. I need to be able to choose our turnover period- say 8 years and have the values start then but in the next prokect I may need a 10 year turnover.
View 3 Replies View RelatedThe attached table mimics the massive table that I am working with.
I wanted to populate values of two variables.
For e.g., I wanted to populate the yellow portion of the table with the value "A"; blue portion with the value "B"; Green portion with the value "3/1/1993" and so on (different colors were used to aid my question only, there are no such colors in the actual table).
I have about 700 such portions to be fill in.
My approach: I just started to copy and paste manually which is tedious.
Question: Would there be any automated way to do this?
I want to assign a cell a formula that changes base on variable, example
myVar=3
Cell(1,1).value = "=average(1:{myVar})"
what do i do to make this work instead of {myVar}?
trying to get it to put the 2 variables into 2 cells in the worksheet for the moment!
The Forms code is:
Private Sub CmdCancel_Click()
Me.Hide
Unload frmMsgBox
Exit Sub
End Sub
Private Sub CmdOK_Click()
Me.Hide
End Sub
It always fills the cells with False and blank, no matter what buttons are pressed (except cancel), so all I can think is that the information isn't feeding back through properly from the form.
I understand the use of Global variables in the sense that they can be used throughout the project. However, I also understand (I think) that unless these variables (like any) are released from memory or the values changed by some other means they will retain their values when accessed inside a another procedure regardless of where the calling procedure is Public or Private. This seems to be a convenient way to access the values of these variables without having to make ByVal or ByRef declarations in the procedure calling process.
Firstly, is my understanding of this correct? (That the variables and associated values) can be accessed from within a calling procedure without formally passing them in?
Second, even if this is true is it considered to be bad practice because the variables will store the last known value which may or may not be correct if you aren't paying attention to how the variable was last set.
My data: four variables A,B,C and D.
A growing dataset representing a group of people being nominated in different weeks for different jobs in different locations. Within a week and over several weeks an individual may be nominated for any number of jobs, in any number of locations.
A=week number (52 possibilities), B=job code (20 possibilities), C=location (2 possibilities), D=name (500+ possibilities) .....
For example, I have the numerical value "400" in R1C2 and that value would be used in the name "D400" which is to be assigned to R1C1:R5C2.
The code I have is:
Range("R" & DRow & "C1:R" & DRow + 4 & "C2") = "D" & Cells(DRow, 2).Value
but is throwing up the error:
"Run-time error '1004':
Method 'Range' of object '_Global' failed
DRow increases dependant on other variable data.
Also, am I right to be using R1C1 instead of A1, or can the same be achieved using A1 references? If so, I think I may not be able to see the wood for the trees.
I have 2 worksheets. The first sheet has data of which some needs to be copied to a second worksheet. The trigger is a value found in column E. If a match is found, then a copy statement needs to be built. The values in F, G & H are the values to be used in the copy statement. The content of cell H may be numbers or letters or both.
What is the correct format of the copy statement?

I have a worksheet which I've set to read-only, I am trying to get it to pull in information from external worksheets. I've created a Macro that will automatically bring in the data however it will only go into a pre-defined cell/row. I have another Macro which looks up the next available row (which is where I want the data to go) but can't get it to link into the macro's. In short, Macro1 brings in data, Macro2 finds next available row, Macro3 brings in another worksheet, Macro4 finds next available row etc etc.

I have three variables; Independent variables x & y, and dependent variable z. x & y can take the values 1,2,3 and can equal each other z can also take on values 1,2,3 but can never equal x or y.

I have a query about using Array Variables in excel VBA. I have a set of lookup tables and a main data table. The data table will be downloaded everyday. I need to replace the ID's in the main table with actual data from the Lookup tables.
e.g.
Main Data Table
Color Operator
005--325 005
004--326 004
003--327
001--328
002--322
Lookup Color
001 - Red
002 - Blue
003 - Green
004 - Violet
005 - White
Lookup Operator Table
323 - Operator 1
324 - Operator 2
325 - Operator 3
326 - Operator 4
327 - Operator 5
328 - Operator 6
I have a huge amount of data in the main table. So I can't use a lookup formula for automation. Rather I would like to use VBA to create array variables, scan and copy the lookup data into the array and replace the ID's in the main table.
Only that I am unable to achieve this using arrays. I am very basic in executing code related to Arrays.
I've a big problem getting the Constraints in excel solver to use variables.
It seems that the only accepted variable type in the contraints are STRING variables. THe following simple example works AS LONG AS the variable apa is a STRING value and as long as it doesn't contain decimals....
So the question is. How to use varialbes in the FormulaText argement other than string values as integers?
This Sample is the code that I've adopted for my use.
My problem is this. My normal target .zip files are in the neighborhood of 75 - 80 Mb in size. Yes I know that they are huge..... (They are backup files for mainframe extracts ) Each zip file contains in the neighborhood of 2000 files. Currently, I have coded two ways of extracting data. Well really only 1.
1) I specify a location to extract all files. Which is time consuming ast it takes in the neighborhood of ( 5 min I thing for all files to get extracted ).
2) If I let the user specify a file filter parameter ( part of a file name ) while the WinZip shell is extracting files I'm searching all the file names in the dest directory and deleting the files that I don't want.
So what I want to know is it possible ( without buying software ) to be able to get the filenames of the files in a WinZip file.......
I have a ListBox in my worksheet "A", and I'm tryin to acces to it... I want to use that ListBox like a log to print the error i have found while running my code. The name of that ListBox is "IncongruenciesListBox".
now if that ListBox was in a userform, i can access to it easily, but if it is in the worksheet how can i change (add more rows) to it?
I tried:
Dim WS As WorkSheet
Set WS = ThisWorkBook.WorkSheets("A")
If added = False Then WS.IncongruenciesListBox.AddItem ("error")
And there is a message saying it cant find "IncongruenciesListBox".

I would like to know if it's possible to access a worksheet in an Excel spreadsheet using a pre-prepared string or character-set? Usage is for years consecutive, so worksheets are '1990', '1991', '1992', etc.

I am currently accessing data from one worksheet to another using: =INDEX(AD!C:C, MATCH($B9,AD!$B:$B, 0)). Ie from my current worksheet ‘Claim’, I’m going specifically to sheet ‘AD’. My full workbook contains 18 sheets, one for each of 18 engineers and of which, the name of the worksheet is the engineers initials. What I would like to do, is to use a lookup table located on ‘Claim’ which will hold a list of all 18 Initials, so that when an engineer selects himself from a drop down list, his initials automatically populate cell K7.
My question therefore is, is there a way of substituting the ‘AD’ in the formula: =INDEX(AD!C:C, MATCH($B9,AD!$B:$B, 0)) with the contents of K7? Or, if you can see what Im trying to do here, is there any other way of accessing specific sheets by inserting the sheet name into a formula?
