View 1 RepliesWhat I have is a listbox and a text box. I want to be able to select the items in the listbox (selection mode is set to multiextended). The problem is
Dim path As String = ListBox2.SelectedItem & " " & ListBox1.SelectedItem & ".txt"
'the line above creates a path with the title of an item from listbox2 + listbox1 and adds the .txt extension.
For Each item In ListBox3.SelectedItems
TextBox1.Text = item
Next
'this just makes it do nothing.
I have also tried diffrent methods to export an item title to a text file. for example I tried:
Dim path As String = ListBox2.SelectedItem & " " & ListBox1.SelectedItem & ".txt"
For Each item In ListBox3.SelectedItems
File.CreateText(path)
Next
'this just gives me a IO exception
It does create a file but it does not contain anything.
Im pulling information from SQL and filling a datatset, im then trying to add the items from the dataset to a listbox and i cant figure it out, iv tried many ways but with no luck
[code]...
Iv checked and checked again and i know the DS has information in it
I have a list box that is bound to a datatable, which works fine. The question I have is this. I have a list of values in the form of a sqlDatareader that I want to use to select values in the list box, that is to say if the value from from the datareader matches the value member from the row in the listbox then select the row. I've come up with the following code, but can't find the syntax to utilize the SetSelected method.[code]...
View 5 RepliesI am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesI'm exporting datagridview data to Excel via dataset.Col 1 of my datagridview contains dates and the grid shows the dates w/o time.Once exported the dates to Excel, they are then formatted via wSheet.Range("B:B").NumberFormat = "ddMM"..The above code works fine for dates having a single digit day. For days 10 and above, the dates are shown as dd/MM/yyyy 00:00 in the excel sheet.[code]If days are single digit, month is swapped with day when writing to Excel from a dataset.
View 13 RepliesSo I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

I am trying to remove items from a listbox based on the items on another listbox, this seems simple but apparently[code]...
View 1 Repliesprobs a simple answer but my mind is blank atm. I have this code to move all items from listbox3 to listbox1 but it wont move them unless i select 1, then it moves all items.

I'm making an application that does some stuff involving the given subject, so this is very crucial to the completion and efficiency of my application.What I'm in need of today is simple (well, "seems" simple). I have one listbox that I want to populate with directories file's names. I don't mean the files inside the directories, but the names of the folders inside the directory.So, I have "c:empdog", I'd click on my button or whatever and search for the directory and I choose "temp", said listbox would show "dog".
UPDATE: Oh, BTW. It doesn't HAVE to be a listbox, it can be anything (IE: Textbox, Labels, Etc.).
I use the following loop to add the Item "email" of the first 10 rows to a listbox.
For i = 0 To 10
s = ETAPDataSet.Tables(DBTable).Rows(i).Item("Email")
lstContacts.Items.Add(s.ToLower().Trim())

my homework question is to display the selected items from a listbox (multi-extended) in a label. I need to display all the selected names in a label. the simplest most uncluttered way of doing this. This is what I've got but it doesn't work.

Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

I have written my main program which uses a datagridview however I seem to be struggling when trying to access the dataset items that have been deleted. Just before I commit the changes I want to record the user that deleted the items.

View 2 RepliesHaving found the following post on datareaders Topic Posted On DaniWeb i have managed to successfully create a datareader in a class that updates a listbox on the calling form with entries retrieved from a SQL server database.I was wondering if it is possible to achieve the same thing using a dataset?My ultimate aim is to read a SQL table / view of information (ie customers), add this into a list box so that when i click on a specifc line in the list box i can then use that selected entry to do something further (ie click a line and then an edit button to edit that records details)[code]

i 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 11 RepliesVisual studio 2005 - vb.net..I have a user control on a form containing 15 combo boxes.All contain Y, N, and blank (for Yes, No, or blank) in the Items Collection property.Each of the combo boxes have a binding source to the same table, different fields.When you select a value Y, N, or blank for any of the fields and do a save, the values save while the application is open.Once you close and reopen, the values are gone.It appears the dataset does not recognize the change, so the values are not getting stored in the database table. Is there something I can do or put in one of the events that would identify this as a change.

I am using Visual Basic 2008 Pro. I am trying to figure out how to bind a set of column headings in a DataSet (or DataGridView) to a ListBox. I want to show the column headers in the listbox control (not the data), and allow users to select one or more items
View 4 RepliesI have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String)
Try
TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
i have a list of items in a listbox and i want to move all of them into another listbox. I'm using a loop to do this but it always generates an exception anytime the loop's counter equals 2. Currently there are only three items in the former listbox. The first and last items are moved correctly except the second.[code]
