View 2 RepliesSo I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra.Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.
What I wanted to do was to create a new list box (lbOrderId). What I want is to be able to select a person from lbMatchingAccounts and have all their Orders populate in lbOrderId.

How to make a text file importer, I want to know how to import list of names from the text file to import it to the listbox component by using browse commands and button. And by using webbrowse component to load the link [URL] and insert the name selected from listbox from loaded names on the text box of my url and click the button signup.
And after the name is added and clicked the signup button from my web automatically to remove the names from the listbox. And after every click of signup button to refresh the link and insert next name and continuously do like that. I need this to send registration link to my members that applied their emails on my site for being informed when site will be launched.
I got my code to read a txt file and import it to a list view. (that is on the form2)so on my form i I want to grab the value of listview1 line 1 in form2 so I tried
dim input_list as string = frm2.listview1.items(i)
But I get an error then I added .tostring in the end and with luck I got something like listviewritem {Jhon}but I only want jhon. Dont want to add trim or delete?
I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
I would like to create a little list in my Windows Form showing a list of custom colors with their 'friendly names'. Technically it can be anything (ListBox, ListView, Panel etc... whatever).
I simply want it to look something like this:
I would like to store data for this list in a simple TXT file in such form:
Quote:
Blue,Blue
Red,Red
#F6A118,My favourite color
#004080,Another color
And of course I would like each element on such list to be clickable, so if I'd click 'My favourite color' it should return the color's HEX value (#F6A118).
When .Clear() is invoked, is the memory freed up that was allocated when all of the items were added? I need to load several lists of codes from a database depending on the import selected by the user. Each list of codes will be a List(Of String). My idea is that I will load only small strings into a List(Of String) along with a List(Of <class>) for the data I will be validating and manipulating. When I am done, I want all of the data from the Lists to be purged from memory. Will .Clear() take care of that or does the memory still remain allocated and have to be dumped by the OS once memory gets full? (And, incidentally, what causes the OS to decide which memory blocks to dump? FIFO concept?)
There are so many lists, I'm not sure if I just want them sitting in memory or not. Granted, the lists will just consist of a single string value for each code pulled from the database. So there won't be a ton of data, so maybe I could just load all the validation lists at the beginning of runtime and only worry about purging the data List since it will contain between 35-50 "fields" per record and there will be a couple thousand records each import that is run. I don't want my program to actually cause a hit in performance in the long run. I ultimately don't see a problem because I won't be running millions or even hundreds of thousands of records at once, but I just want to be sure.

We had a wierd problem at work.SOmeone at finance tried to import a text file into their system. It complained about the textfile was in unicode format. The file contains scandinavian . Apparently the ERP system that exported the file can only handle unicode.So one of our junior programmers wrote a batch program that line by line converted the unicode file to ascii (you can't choose encoding.ANSI because ANSI is byte array)
The files are rather big, about 3 GB in size.Apparently the system liked ASCII files, but sadly after this processing the and was gone and replaced with ?So, he wrote a new batch program, this time replacing m?nad with m�nad using String.Replace The file was opened using Encoding.Default and saved using Encoding.Ascii.Now the files HAVE AND can be imported. After he explained this to me, I just went . I wish I had some nifty "you should have done this... bla bla its much easier" but I am lost here in the jungle of code pages and encodings. Can someone that has their head screwed on straight enlight us *both* about why we had this problem and how it could be handled without writing the second batch program?
Basically unicode->non unicode (ascii) with the intact. I also noticed that if I use streamreader to read an ansi file with the internal strings will show ? instead.
I am once again working on a project and have hit an absolute wall! Here is what I'm trying to do:
1. Create a Userform that has one textbox and one button.
2. Have the user enter text in the textbox and press enter.
3. Once enter is pressed have the form take the data they typed into the textbox and search a specific .txt file (beginning the search from bottom to top to find the most recent entry) until it finds a match.
4. Take the latitude and longitude to the right of the match and convert them to proper form. Right now my SQL provides live updates to the .txt file only the lat/lon come accross as |-112053440|33427640|, so I need to insert decimals in the correct places.
5. Either way, they type "c123" it will search until it matches that then take the latitude and longitude that is to the right of the match.
6. Convert the latitude/longitude into proper format because if it pulls the data as is it will appear as[urls]...

I have written some code to save the contents of the account and password columns in the format Account|Password.
