Pasting Arrays Into Excel Ranges
Apr 12, 2012
I'm working on pasting arrays into excel ranges. Suppose I have a range: A1:A5 and an array a = {1,2,3,4,5}. I can set up the problem like this:[code]So, I got curious about the Transpose method, and whether I could construct my array properly so that I didn't need it. I found that Transpose converts my array into a 2d 1-based array (so the first element is (1,1) not (0,0) as usual).Now I'd like to know: Is there a standard VB-way other than the worksheet transpose function that I can use to build a 1-based 2D array the way Transpose does?

I am using Excel interop in my VB.NET program. My problem is that I can't seem to figure out how to write to Excel *and* define the Range using numbers.Alright, so I have objects being created depending on the file that the user opens. So there could be 100 objects or there could be none. Now each object has an array of values, and these arrays contain nearly 15000 elements. So here is what I want to do but I can't figure out how to escape using the LetterNumber:LetterNumber combination.
For every object I want a new column to be occupied and for every element in the objects array I want the row to be occupied. I figured the easiest way to do this was using a for loop but, again, I can't use numbers.
For columns = 0 to NumberOfObjects
For rows = 0 to NumberInArray
Cell(0,0).Value = myObjectsCollection(column).Array(rows)
Next

I'm trying to copy a Range from Excel and Paste the information in powerpoint in either the HTML or the default format, however, I am having some difficulties. I am able to get the code to work for pasting the Range as an OLE Object but nothing else. The problem with doing this is that having the embedded excel documents in the powerpoint makes the file extremely large and unstable. I just need to be able to paste the information without the embedded information where it is editable (so, not as a bitmap or picture).
With ppt2Slide
Sheets(index2).Activate
Range("CP12:CT" & RangeIndex2).Copy

I created an e-mail program in VB2008. I have an excel file with a list of all e-mail addresses and attachments to those e-mail addresses. What I want to do is import thethe e-mail addresses and attachments into my program. I want my program to then take each e-mail address (automatically) and insert them with their attachments into their respectable fields in the program. The primary objective is to insert 200 e-mail addresses and attachments. Each attachement is significant to each e-mail address.

I have to compare two columns in two different Excel sheets and delete the duplicates. I have come up with several strategies that work, but I am searching for the most efficient way to do this. At first, I was sorting the columns and looping through them in the manner of a sequential update and deleting when the cell values were equal. But I discovered here an article by Mike Rosenblum that explained that it is much more efficient to stick the columns into an array and iterate them from there. So I was able to do that. There was a complication in that once I had deleted a row, then the array and the spreadsheet were out of sync. So I had to compensate by incrementing a variable each time a row was deleted, and subtracting this variable from the array index to calculate the row to be deleted in the spreadsheet.
So now I am wondering whether there is a better strategy. I thought that if I could merely hide the rows to be deleted and then find a way to delete all hidden rows at once after the loop was over, then this would eliminate the problem of the array and the spreadsheet getting out of sync and would make the code easier to understand. I thought of putting the row numbers of the duplicates into another array and deleting the rows after the comparing loop. But this creates the same problem of having to compensate the row numbers in the array.

Basically i work as a desktop support officer. our team does everything from fixing software errors on PCs in the office to moving them from one desk to another. When we do have to move anything though, it needs to be tracked so that our records can be accurate. To track where things have moved to, we have to:
1. fill out a form in an excel format and then fill out the same information into a text file format, and then attach both formats to the job record in our job listing system and send it to our hardware tracking team.
2. If an asset is being taken away to storage, but is considered to be too old, it needs to have an excel table filled out to create a 'disposal' label, or it can create a 'redeploy' label if it still has some years left in it.
3. If we are putting out a brand new asset, it needs to be updated on our tracking sheet to show that the asset is no longer in our storage as brand new.
This obviously creates a lot of administration work for our staff, so i have built my program to take all the information required once, and then split it off to the forms and labels as required.The part I'm stuck at is number 3. I have been working with the excel files in the following format:[code]What i need to do is as the title suggests, search an excel work book (the user will point to it) for the Asset Number in a particular sheet. Once it finds the asset number, cut the entire line out of the sheet and paste it into a different worksheet at the next empty line with a few edited values.

I'm creating a windows application using visual studio. My code is in visual basic. I want to enter a "Browse" button where the user will click on it and select an excel file from his computer. Then,for each column of the excel file, I want to create an arraythat will contain the same data with the column.Only the first sheet will be necessary and it will have specific number of collumns. I won't know the number of the rows, I will be needing a counter for these as well. My object is to have these data as arrays and to be able to make some calculations.

To write code to implement data from visual basic into excel. Write a VB.NET program to store the following numbers into an array named �Scores�: 89.5, 76.2, 90, 86, 81, 97, 61, and 73. Your program will calculate an average score, list each of these scores in a new Excel workbook and show whether each score is below or above average. Your program will then save the Excel workbook as TestScores.xlsx.
In column A1 it should say "average" and next to it (in b1) should have the average of all those scores. in the cells below (starting from A3) it should list the scores and the column next to each score it should say whether each score is above average, average, or below average (compared to the average calculated in cell b1)

I am creating a program that takes into account pay from a job. I will try to describe the problem I am having using some psuedo code - so dont take syntax too seriously.
I created a structure that has some of the following values:
Name as String
Amount as Double
FrequencyType as MyEnumerator
MyEnumerator looks like this:
EveryTwoWeeks = 1
TwiceAMonth = 2
Weekly = 3
Now my problem is how do I add the date ranges into my structure?If your pay is weekly or twice a week, then I just need a single date because all other paydays should increment in 1 or 2 week blocks. But if the pay is twice a month I need two dates. It seems like there has got to be a better way then just having two dates in my structure and knowing that you just need the 2nd date if the FrequencyType is = 2 (TwiceAMonth).I was thinking that instead of a Structure I should use a class and then I could create a function that returns the date or dates depending on the enumeration type that you pass into it.What would be the "correct" way of doing this? I think I need a type of enumerator that allows for more then just integer type values.

I am developing a billing application to help out the billing lady who has been doing our billing by hand. I am essentially done�. Except for one class of customer I can�t wrap my head around. Nuts and Bolts:
1.Data comes from a table that shows Storage id, customer id, Billing Start date, Billing end date.
2.I am kicking the data back out to a table and I�ll build her a nice little crystal she can run.
Problem:We rent storage space. If multiple customers use the same storage then they will split the cost of the daily fee. If there is 3 customers they each pay a third etc. This seems simple but If Customer 1 starts on 1/1/12 and ends 1/10/12 she pays 10 days. If Customer 2 comes in 1/3/12-1/9/12 they will split 7 days. If Customer 3 comes in only on 1/9/12 then they will all pay a third on that day. Now imagine this across 600+ storage units and 1000+ customers and each customer using multiple storage at any given time.
My biggest issue is I don�t know how to express how we do that calculation by hand programmatically. By hand process and how I figure I am eating the elephant: Find every Customer that has used the Space in the billing period -Determine the unique storage numbers that were used during the billing cycle kick the results to a storage table on an access database. I am using a table because I figured it would be less of burden for the application then a list or array.
Determine where there is overlap - Use �FOR� to cycle through the orginal data table using the unigue. Here is where I am stuck. How do I compare the dates in a way to determine which customer is using it when compared to the others. Obviously i can determine the difference in dates between the start and end. It is getting the applicaiton to recognize the dates are with in the other dates. here is kind of what I was thinking obviosly this doesn't work I am just using the format so don't crush me too bad because I code like a caveman.
Dim CustomerDifference as time span
Dim UniqueStorage as Integer
Dim Customer as string

What's up guys. Simple question today. How do you specify ranges of values for location? Basically i'm trying to write an if statement that will execute if a location matches a range of values, here is th snippet of my code im having trouble with:
If Player.Location = New Point(0 To 240, 240) Then code here
But that didn't work at all, there was no error, but the code just wouldn't execute when the "player" was in that range!

I am trying to make a program, where a user will input 'ranges' in a richtextbox, and then enter a value, which will be stored/categorized (in an array maybe) according to the 'range'.What I exactly mean is:
User specifies ranges by inputting this line in the richtextbox: <,10,20,30,> First range = < to 10 (no minimum boundary up to 10), second range = 10 to 20 , 3rd = 20 to 30 , 4th = 30 to > (30 to no maximum boundary) Then a user enters a number. For example "-1" would fall in the "< to 10" category, "23" in the "20 to 30" category, "125" in the "30 to >" category. I know there are other ways to do this, but I would like to see a solution (or some guidance) based on these requirements.

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working
