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.

View 2 RepliesHide Item In Combobox?
Jun 29, 2007vs2005 -vbI have a combobox that gets its values from a call to the db. I have programatically added the list values for the box to match all the possible values that could be pulled from the DB. The user can update these values and update the db entry.I would like to be able to display any entries from the db, however, there is one value on the list that I don't want the user to be able to change the combobox's value to. I'm hoping there is some way to to 'hide' or '.visible=false' for just this one item when the list drops down so the user can't select that value.The box sits in a datagridview. I realize I could use the 'cellbeginedit' & 'cellendedit' events to prevent this action, but I consider that to be a last resort, as I think not showing it on dropdown is preferable code-wise.

Select An Item In Combobox?
Oct 9, 2009I have a combo box with a list of book conditions. When a book is loaded into the form, the condition the book has needs to be selected. How can I do this? Here's what i have: Excellent Very Good Good Fair Poor just for example, how would i select "Good" WITHOUT USING THE INDEX? The database knows the condition text, and condition id. I need to select the condition in the combo box with either. However, I don't know how to add the condition id to the items in the combo box. How would I do this in Visual Basic 2008? **EDIT** I forgot to mention, although i am using a database, i am NOT using SQL Server. I just need a way to select it with a variable containing either the id or condition.
