I have a Report I created with Visual Studio's VB.Net ( I guess this makes my report embedded), which I can select a date range like starting and ending date but the drop-down listbox for the Name is empty and I have to type a name into it to work. I need to be able to choose the name because I won't know who is on the list.
I'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.
Private Sub EditStock_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Try Dim dsitemlist As New DataSet Dim itemlistadapter As New OleDbDataAdapter _ ("SELECT ItemName FROM Stock", ConnectString) [Code] .....
And here's what shows in the box. system.data.dataviewmanagerlistitemtypedescriptor
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've been working on this for three days now and I can't seem to get my listbox to populate. I'm connecting to an sql database. Where am I going wrong? Dim cmd As New SqlCommand("SELECT DISTINCT natureport FROM rates ORDER BY natureport", conn)
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 drivestring As String = lstBoxDrives.SelectedItem.ToString Dim directoryName As String Dim fileName As String Dim accesstime As Date Dim FileProps As IO.FileInfo
[Code]...
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'm doing a win form application in visual studio 2008 and using 7 listboxes where my sql query will populate all customer from customertable. It's 7 cause it's one for each day, my problem is to get customerid when I select one of the customers from any of the listboxes to my textbox. Since there are 7 listboxes I can't use "data bound item" function, in that case it would be easy to write code like this: textbox1.text = listbox1.selectedvalue.tostring(

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 Next
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
[Code]....
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.

Is there a way in which I can populate my listbox with an Access (.mdb) database and search for values in it. Also, can I move selected values back & forth from that listbox to another listbox (or textbox). Is this possible using Visual Studio, VB.Net?
im trying to populate a list box from a text file using the System.IO.StreamReader class and my code blows up right here:[code...]

I made a program in Visual Basic 6.0 and am trying to convert it to vb.net.so i am at the stage where the program needs to load the Access file and populate the listbox according to which radio button i chose.
I have a listview with checkboxes on the left side and 2 columns of data. What I want to do is populate a listbox when the user checks a row in the listview. I've tried code in the Item_Check event. It does not pick up the item checked. It's as though it's behind. For example if my listview has a list of country codes and I check US, the code returns nothing but if I check another item, it picks up US. Same thing happens in the SelectedIndexChanged event. If I use a button, all works as expected.
I need to populate data (Patient ID and name) from a MS Access Database table (PetientInfo) into a listbox depending on date (Datetimepicker). The listbox item will change upon date changed.
When I select a item from listbox the details of the patient will show to the textboxes.
