I'm trying to build something called a structure which will store data it retrieves from a text file. I have the structure set up like this:
Structure Employee
Dim FirstName As String
Dim LastName As String
Dim ID As String
Dim Hours As Integer
Dim Wage As Decimal
Dim EarnedPay As Decimal
End Structure
[Code] .....
How to set these operations up?

I'm designing a choice based adventure game in VB.NET 2010, where you are presented with a story label, and you choose between 2 buttons, which choice you want to make. I want to know the most efficient way to do this.My goals are to store the labels for the buttons and the story in some form of data structure, which is temporarily a hash table right now, and some form of structure for the choices. Right now I am using a custom class that references the indexes of the next 2 choices and their respective label indexes which stores the class instances in a hashtable.I've looked into things like arrays, dictionaries, lists, and collections, but I'm not sure which one best fits what I'm after. Any .NET data structure would work. What is the most efficient data structure for these 2 pieces of data? Would just a string array work?
View 2 RepliesI have a insanely large file that has a lot of customer data in XML format. The start of a customer and end are how I'll determine the starting and ending points of the customer data I need to extract. The is the number I'll be searching for. I'll input a regular text file with 12-byte document numbers into the file (Doc Number List.txt), search the massive XML file (example.xml) for those document numbers, find the data before and after the DOC_NUM tags, but within the CUSTOMER tags and extract it to a formated file. The formated file needs to have these tags, <?xml version="1.0" encoding="ISO-8859-1"?>

The only problem is, how do you place an image with its file name with the form-data along with the API key? This is what is stumping me in trying to implement the function.By the way, OpenDialog is already implemented to select the file to upload.
Update: I tried adapting the existing code to use the Unified API and it still does not work. If anyone knows what's wrong in the code, just make the modifications... Otherwise,

i have been coding for years, but never integrated XML. So I guess I'm a newbie. I have inserted an XSD file in my project, ARequest.xsd. I created a folder in my project called XML just to organize things, so this file ARequest.xsd, is in this folder.
Now I have a form that displays data from a database that has the same fields that are in this XSD file. Can I load the XSD file into my Windows Form, load the elements from the data on the windows form and then create an XML file then send it? If so how? Any code snippets would be helpful. Now I do know how to create the XML file, we'll call it Test as

currently working through a project using VB 2008 windows form application and having a little trouble with the code. I need to read data from a text file into an array of a structure, displayed in a list box and have a number of searches conducted on the data and these results displayed on the form. The test data is of rainfall across a number of areas and is in the format:
I have a csv file with 48 columns of data. I need to open this file, place it into a data structure and then search that data and present it in a DataRepeater. So far I have successfully used CSVReader to extract the data and bind it to myDataRepeater. However I am now struggling to place the data in a table so that I can filter the results. I do not want to use SQL or any other database.
So far, this is working in returning all records:
Private Sub BindCsv()
' open the file "data.csv" which is a CSV file with headers"
Dim dirInfo As New DirectoryInfo(Server.MapPath("~/ftp/"))
Dim fileLocation As String = dirInfo.ToString & "data.txt"
Using csv As New CsvReader(New StreamReader(fileLocation), True)

I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure).LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file.I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure.When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure,populate the structure from the data file, then call the method to transfer the data back to the website.
How do you recommend I transfer (copy) an instance of a structure from one .NET program to the VB.NET program that executed it?
i was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?
View 6 RepliesOur application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

I am new to the forums and just started to learn vb.net. Currently I am making a project that require a lot of text. Since I would need over 20 labels and do not want to hide every single one, is there a way to place text on a specific place on form through coding. Then, I could just make it a sub and easily hide the text and reveal it
View 2 RepliesThis is probably easy but it is eluding me. I need to place text on a picturebox. I import an image (can be various sizes) and place it on a PB. The PB is in stretch mode. I can place text onto the image but because each image can be a different size the text is scaled to a different size for each image. I need the text to be the same size regardless of the image or PB size. I guess I am trying to place text directly on to the PB surface but I have no idea how.

I spent most of Friday deleting stuff out of my windows project and/or starting from scratch when the data base was changed. What is the cleanest way to get the data base and data set changes in place? The current changes(which I have not applied yet) effect the file that I am maintaining in my windows project. Right now, we manually delete the data set project from our local PC, then copy the new one down from it's permanet location on the server.

The idea is to have a central place to put the routine in instead to copy it into every .vb file that belongs to each .apsx code file.
Looking for an idea of where the best place to keep files for a program. I use them frequently and they interact with the program directly. I want to place them in a place where they won't be easy to find if someone is just cruising thru the directories. Any ideas?
