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)

Designing The Flow Of Code When Reading / Writing From Database

Aug 8, 2009

So I'm trying out a concept tool of mine where I need to be able to read and write data from a database real easy. I've set up the form as I like and spread around different text boxes and dropdownboxes to read the data from the database. And I've got it all to work and all, but there's a small bug I don't fully understand why's there. Some textboxes don't update the text from the database.

But it seems as it only occurs if the data in the database is nothing. So the value from the last row is still hanging in the textbox and thus, clicking "Update" actually updates the value from the field from the last row, into the new row. Messing everything up.

Currently I am defining next static functions in derived class for GeneralSelect [which selects all records], GeneralInsert[Which inserts a records], GeneralUpdate[Which updates records as per given id] and GeneralDelete[Which deletes a record of the given id]. The parameter and all functioning are same just the differece is the table name and fieldnames.

Making A Tetravex Solving Program In Order To Practice My Code Writing Skills?

Feb 8, 2010

Well, i was thinking of making a Tetravex solving program in order to practice my code writing skills (language will propably be Visual Basic) and I need help finding an algorithm for solving it. For those that don't know what tetravex is see this http:[url]... . The only algorithm I can come up with is the brute force way, place a tile randomly in one corner and try every possible tile next to it and continue the same process, if it reaches a dead end revert to a previous state and place a different tile.

VS 2008 Visual Studio 2008 Randomly Crashing When Simply WRITING Code?

Oct 25, 2009

i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.

But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.

This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.

VS 2008 Writing Some VB2008 Code To Control Four 7-seg LED's / Serial Port Control?

Nov 10, 2010

I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.

I couldn't write a program using a webBrowser because it might take 15 secs just to load the url. How are they writing the code??

Writing File/Folder Sync Prog, Result Text Boxes Not Updating Untill After All File Action Is Done Even Though Update Code Comes Before Copy?

Apr 12, 2011

I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.

So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

Writing One 2D Array Onto Another?

Sep 7, 2009

It would be easy enough to make my own system for this, but I'm figuring that the .NET library, being as massive as it is, probably already has a class made for this very purpose.For hit detection, my VB.NET game uses two 2D arrays that store the state of each pixel in the level. Each element in these arrays is a Byte (or, more accurately, a value of a flag enumeration type based on Byte).

Public TiHD(,) As HitDT ''//State of each pixel in the level based on
''// its underlying tile.
Public SpHD(,) As HitDT ''//State of each pixel in the level based on[code].....

I would enjoy being able to just give each sprite & tile its own 2D array of hit detection data (defining which pixels of the object are solid, dangerous, etc) that can be directly written to TiHD or SpHD at a specified offset.I'm willing to bet that .NET has a class that can do this for me.Presumably I would just have to pass TiHD or SpHD to the constructor, and then I would be able to use the object to indirectly modify the array with extended functionality (similar to using a Graphics object to modify a Bitmap). Is there such a class?

DB/Reporting :: Writing To A New Row

I am currently making an old school adventure game for a college project, it uses an Access database (dbGameStats) which has the primary key (gameStatsId) which is an auto number. The main form of the game holds the data bindings, dragged into text boxes, and the various screens of the game are shown over the top of the main form. So on the main form I have highscore and player name text boxes, bound to the corresponding database fields, when running the program, the user enters a name, the highscore field is altered as the game progresses and when the user exist the database is updated using this:
