View 1 RepliesMatching Item In ComboBox With Multiple Items In ListBox
Jul 24, 2010I have a combo box with a list of Coordinator IDs, one Coordinator can run many subjects. On another form I have a list box that contains a list of the subjects, and another list box that has the coordinator that teaches the subject. The positions match up, i.e if there is a match for the co-ordinator ID in the list box at position 3, I want to extract the subject list box at position 3 also. The problem is 1 coordinator can teach more than 1 subject. Basically I want to show the subjects taught by the Coordinator the user selects in the combo box.

Select Item From ComboBox And Message Display In ListBox
Dec 26, 2009I have a form like that: What I need to do is when the user selects item1 from combobox a message will be displayed in listbox. My combobox has 11 items so I must have 11 appropiate messages to be stored automatically in listbox . (The message is appropriate of what item is selected from the combobox)
Here is the full code implemented :
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Dim msg1, msg2, msg3, msg4, msg5, msg6, msg7, msg8, msg9, msg10, msg11 As String

Write Some Code Which Parses Data And Then Populates A Listbox
Oct 24, 2009I'm trying to write some code which parses data and then populates a listbox. I'm using the IPWorks IPPort component which basically does the reading of port 30003. The ipport1_OnDataIn event is where all the action is. I parse the data, which works great.. however when I try and do something simple such as add text to a listbox, I get the dreaded error "Cross-thread operation not valid: Control 'lstListBox1' accessed from a thread other than the thread it was created on".I've googled the error and tried copy and pasting some workarounds but nothing seems to fix the issue.
If anyone can offer help, it would be greatly appreciated. If you could possibly show the code already implemented into mine, it would be even better so I can see how it works. It would make more sense to me. My code is below. The part i'm trying to get working is the lstlistbox1.items.add("Test") in Case "2". This is to just get it working.. I'll be adding listbox items in the other cases as well, and they'll be parsed values instead of "Test". This is just to simplify things at the moment.

View 5 RepliesAdd To A Combobox A List Of Item (not Every Item) In A Txt Located On A Server
Feb 13, 2011my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

Change List Of Combobox A Based On Item Chosen From Combobox B?
Jun 17, 2011I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.
