Writing VB Code To Implement In EXCEL (using Arrays)
May 21, 2012
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)

Basically I'm writing a program that records all the financial transactions I make. You type in what it is, whether it is going in or out, the date and the price. I will get on to adding the sums up later but that's important at the minute. With one record the program worked perfectly but as soon as I added an array to the records variable it stopped working and complained about a null value.

Even a primer on just reading/writing to a text file would be golden. The array confuses me further, but understanding the data is primary.
Basically, we're writing a program to manage inventory for a bar. Fields and a few lines are below. The delimiter is "||"
So... How do we read the data into the arrays? NAME would be strName(), etc for all of them.
how to write and update existing data.
UID||BREWERY||NAME||SIZE||FORMAT||SEASONAL||PRICE||CASECOST||CASEQTY||BREWERYLOCATION||BREWSTYLE||ST YLE||ABV||CLASS
A0101.12B||Abita Brewing Company||Abita Amber||12

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.

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 want to write a formula to SUM from column B4 to M4, this should be done using vb.net programming.
I tried using the following stuff:
oXLWsheet.Range(4, 14).Formula = "=SUM(oXLWsheet!$B$4:M$4)"
"=SUM(B4:M4)"
"=SUM(B4,C4,D4,E4,F4,G4,H4,I4,J4,K4,L4,M4)"
Nothing is working for me. I'm getting the following error when I run the code:
"Exception from HRESULT: 0x800A03EC".

Current i'm developing an application track storage of an item.in it abusiness rule says an item can be moved to more than one warehouses. Also i need to keep the history of the Item's history, Thereefore i need to create two entities,"Warehouse" and "ItemsHistoryOfLocations". I have developped an static class diagram to show the relationshop.These are the relationship rules between the classes:
1. A warehouse could be in an Item's History of locations.
2. A warehouse could be in many Items' History of locations.therefore in the forward relationshop -- 1..*
3. In an Item's History of locations, there must be at least one warehouse4. In an Item's history of locations, there can be more than one warehouse
Therefore in teh backward relationship -- 1..* Therefore the relationship betwween teh classes is a M:N. In another Object oriented scripting languaage when ever, and M:N relationship is found between classes, their relationship is slit and put a collection class called "MemberKeyDictionaries" as the bridging entity.But in C# / VB, should we create these collection classe. IF NOT, then how should i modify my class diagram to implement this M:N relationship? and h0w do i implement this M;N relationship in code?

I am trying to implement a progress bar into my code but it seems to not run when another section of code is running. I set a timer to run when the ok button is clicked and it should then start the progress bar but also when clicking the ok button whatever radio button is selected also runs. I am trying to do this in Visual Basic 2008. I will post my current code below and I will say I am a complete novice at this so I apologize if the code looks weird:

I need to port an old Clipper app to vb.net. It relies heavily on user-written macros and indeed would be almost impossible to create without them. As VB is interpreted, I am sure it must be possible to implement code that the user has entered, but I have no idea how to do so!

Very first time I debug the coding I haven't got much problem. But debugging it again gives me an Error AS: "A file named 'Resume.XLW' already exits in this location. Do you want to replace it?"
I was able to see this since I have enabled the display alerts. Disabling it generates a save as window.

I'm working on a project where I have to allow users to write data to an existing Excel worksheet (by entering the data into a form created in Visual Basic.NET). I've created a form that allows users to enter data such as the following:
Name (First, Last)
Mailing Address
Email Address
Gender
Age
...and so on. I've programmed the data to be sent to the Excel file upon clicking on the Submit button in the form itself. I've also created the Excel file and placed it on my C: drive, but the problem I'm having is trying to send the data from the VB form to the Excel file itself. Can someone please show me some sample code or point me in the right direction as to how to get the submitted information from the form to save into the Excel file, please?
I'm trying to get the information to show up in rows and columns in Excel like the following below (the dashes are just to show that the information should be in rows and columns):
Name--------------------------Mailing Address-------Email Address-------Gender-------Age
John Doe---------------------2300 Jackson Street-------- xxx@xxxx.com-------Male---------17

We are working with an existing native application (most likely written in VB) that loads assemblies and calls methods with "Late Binding." We do NOT have access to its source code. We want to implement this interface in C#, and have the native application call our C# assembly. Is this anything we have to do beyond matching the method names and method signatures to make it work?
