VS 2008 Commonly Used Functions
Aug 7, 2009I'm taking a class in VB, so I have numerous projects. I have a lot of useful functions and code, and I'd like for them to all be included in on piece of code that all my projects can use. The problem with DLLs is that when I build, the EXE needs the DLL to be in the same folder. I want a standalone EXE file. Is there any way I can have a DLL in a different folder than the EXE and still use it? Or is there some better solution to having useful code somewhere so when I update that code, it will affect all of my projects?
View 2 RepliesAre Modules Still Commonly Used In Program Structures
Aug 18, 2010I am not a program designer by any means but I would really like to start getting a better grasp of how to do it and a better understanding of the .NET languages in general (VB, C#). I was reading a book by Wrox - Professional Visual Basic 2008. In it I believed it mentioned that Modules are slowly going out of existence. I can see why most coding would go into a class object but I would assume modules would always be necessary to at least keep the code clean.
Also, I have been searching for a good source on software design but I can't seem to find any recent books published. I might be searching in the wrong places but I would really like to get my hands on one.

I can't move on unless I know the parts needed and what the code for one of them is if I can link the save as button on the menu bar to the part needed to save I can figure the rest out besides the format that it saves in.

View 1 RepliesWriting VB Code To Implement In EXCEL (using Arrays)
May 21, 2012To 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, 2009So 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.

How To Avoid Writing Common Code In Derived Class
Jun 28, 2010I am trying to minimize my code writing. I have DBLayer base class that selects, inserts, updates and deletes records from database. I need only fieldlist and table name from each derived classes to perform the actions. I have defined static tablename, fieldnames in derived class. 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.

View 2 RepliesMaking A Tetravex Solving Program In Order To Practice My Code Writing Skills?
Feb 8, 2010Well, 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.
View 4 RepliesVS 2008 Visual Studio 2008 Randomly Crashing When Simply WRITING Code?
Oct 25, 2009i'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.

View 3 RepliesVS 2008 Writing Some VB2008 Code To Control Four 7-seg LED's / Serial Port Control?
Nov 10, 2010I'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.
View 7 RepliesVS 2008 Writing Submission Code (submitting Urls Or Pad Xml To Directories - Submission Sites - Blogs)
Dec 13, 2011I'd like to know if there are other ways to write a submission program (submitting urls or pad xml to directories, submission sites, blogs) other than using the webBrowser. I've evaluated some shareware programs that submit urls or data very quickly, like 100s in a matter of mins. 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??

View 13 RepliesWriting 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, 2011I 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.

what I am trying to do is is compare the input with the output.so take the first two characters in textbox4 and see if they are the same as in textbox1. then take the second two characters and see if they are the same as textbox2.
I know how to do it for just one string of characters but I am not sure how to seperate out different letters in one textbox.
