I am a new in the programming so I need your help this is my first application. I have one richtextbox and one listbox and I need import all lines from the richtextbox to the listbox. I am using Google translator because I do not speak English.
I need to load line by line the richtextbox into the listbox. Please I need help because it is my homework in my school.
I have a richtextbox in the form1 and I textbox in the form2 with a text example "hi, have a nice days" so I need to save this text into the richtextbox. So I need code in a button in the form2 for to save the text into the richtextbox in the form1.
View 8 Repliesi have a Userform that I created in MS Word that automates almost half my job. I'm just looking to re-create this form in VB.Net so that I can keep up with the trends.What I did previously was load a listbox based on the contents of a data table in another word document. I've searched for other methods of creating a datasource in VB 2010 Express but I'm unsure how to load the contents of a dataset or datatable as opposed to a table from MS Word. Ideally, I'd like to abandon using Word tables and create a dataset in VB and load a listbox based on that. I do not have a copy of MS Access and I'm unfamiliar with MySql, which I'm guessing would are the easiest methods of loading a dataset. I also thought that maybe if I could create a seperate form (let's just call it form1) specifically for entering new data and saving the form as data is added, then linking the datasource from that form to a second form (form2) that has the listbox that will populate with the contents from the data in form1.

View 10 Repliesthe data that its inserted on the listbox comes from a access db i have this code but this only works when theres only 1 line on the listbox this code works fine when i make a search in the db by the code of family(because the family code its a primary key there can only be 1 family width that familycode) so when i get the family surname i clic on it and i get a form telling me info about the family. but if i try to search for the family surname there can be several family whit that surname. when i search the family surname the listbox will show me all the family's that have the surname now what i want its when i search a surname for eg"Smith" the program will display all the familys that have that surname and i want a code that can give me the number of the family i clicked.[code]
View 1 RepliesI'm working on a program that will be a semi-autosubmition in web directories. I need an ideea for my directory list.I want to able to navigate from one directory to other with a "next button". Now I'm using a listbox saved in a text file, but i don't know how to make the selection for "next directory".I'm only able to click on the list. And what I thinking was if it is posible to have a better list, advanced, like a table with more columns like: url, if url is valid, pagerank for example, and maby sort by this filtres.

View 1 RepliesI've given up on my harder stuff and have simplified it to something else. There are no errors that pop up now but the list box doesn't populate! I took the code from a book and there's a data adapter, data connection, and data set on the form already (they're not named in this code though, since the book didn't say to). When the program opens, the list box has a line of text in it and the list box doesn't fill with the right items.

I come from Access and I am developing now my first windows form app in visual basic 2010 based on a Access database *.mdb. The thing is i have an access db with 5 tables. I have created the forms, connected to the database, all is working great. Parent- child relations are working, datagrids and comboboxes populate the right way, buttons are working.
But now I want to populate listbox, and combox from tables with queries. Like in access I would like, for example to populate two different listboxes bound to the same table with different queries, so that the listboxes give different results, based on different variables or textboxes.
But I don't know how to attack the problem: the query works against the tableadapter, so the info it gives back is always the same. I have tried to duplicate the tableadapter of the table i want to query, writing different sql queries in both, but it does not seem to work. I don't know in what direction I should ivestigate: LINQ, sql queriess, coded queries, filtering the listbox...

I'm trying to populate a listbox with every file that was last accessed more than a year ago but I've hit a snag, i cannot get the fileinfo for some files because the path is too deep, is there a way round this

Dim directoryName As String
Dim fileName As String
Dim accesstime As Date
Dim FileProps As IO.FileInfo

The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.
I can get a single column but how do I get 2?

I'm doing a win form application in visual studio 2008 and using 7 listboxes where my sql query will populate all customer from customertable.

I am trying to populate an array from a listbox.My listbox items contain something like this:
1 for January
10 for February
3 for March
I have code in place and it was working, but I am taking the first character of the listbox item to populate the array. If the value of the listbox is 10 for February, I need to get 10, not just 1. Can I do something with the string that says I want to trim everything from the space to the end? Since they are all formatted the same way, if I could trim out anything from the space on, that would work.
Here's what I currently have:
ReDim m_adecRainfall(m_astrMonths.Length - 1)
For intCount = 0 To m_astrMonths.Length - 1
m_adecRainfall(intCount) = CDec(lstMontlyRainfall.Items(intStart).ToString.Su bstring(0, 1))
intStart += 1

I'm trying to get a listbox to populate a list of processes that are neither running nor in the "blocked" list. This code is in a timer, so it also checks if the process is already in the list.
For Each proc In Process.GetProcesses
Dim allowed As Boolean = True
For Each item In Blked.Items

It is strange because this is populating the list, but adding the same process over and over again, even though I seem to have the checks in there.
Here's my code, all it does is display the numbers 1 - 10. I want it to display the numbers from the column Sales, from the table Songs.
