Add To A Combobox A List Of Item (not Every Item) In A Txt Located On A Server

Feb 13, 2011

my 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, 2011

I 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.

Display XPS Document Using A Selected Combobox Item?

Dec 26, 2011

I am very new to programming, I have developed my first application - an xps viewer. What I want to achieve is to be able to allow the user to select which document to open from a range of options that I have predefined in a combo box. I've searched all over the net and can't find an article that shows me how to do this. MSDN is bit too cryptic for me at this moment, so I get confused.

Select A ComboBox Item Which Is A Drop Down List

Feb 28, 2011

i seem to have a problem when i try to select a ComboBox item which is a drop down list. The ComboBox contains a list of various items where the user can select from a list, the type of query he/she would like to perform on an Access Database. Two of the items in the Drop Down List are "Employee Sales Between Specified Weeks" and the other item is "Employee Sales Between Specified Months" (without quotation). Now in my VB code, i have a really long If/ElseIf Statement which includes all the options the user can select. Additionally, if the user has selected a week query, he/she must select a From Week, a To Week and a Year (for example week 3 to week 5 year 2009). From Week is another combobox (1-53 weeks) and To Week is also another ComboBox (1-53).When the user selects a month query, he/she should select a From Month from a ComboBox (1-12) and a To Month from another ComboBox (1-12) and the year from the same Combobox (e.g 2009).

Fill Combobox With List And Select Current Item?

Dec 11, 2009

I have 2 linked DB tables, Artists and Albums using ArtistID as the primary/foreign key.When I want to add a new Album, I have a new form open and I can fill a combobox with the list of Artists to choose from and edit all the details then save to the database.

However, when I want to edit the Album info, I can't seem to get the Artist associated with the Album, as well as all the rest of the Artists from that table, (in case I need to change the Artist associated with the Album).The information required comes from 2 linked tables, so that's where I'm getting lost.An example of this is when a person edits their profile on a webpage, for instance, a list of countries is usually listed in a combobox and the one selected is the country they selected when filling out the form previously, however, they still have the option to change it.

I have a combo box that has a drop down list with long values in the drop down
Ex:

LB - Pounds
GR - Grams

When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows

When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

Possible To Make List Box Item Height For Item Depending On Amount Of Lines That Item Contains?

Jan 1, 2012

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

Get Selected Item Index Or A Sorted & Grouped List Relative To Item Source?

Feb 12, 2011

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.

What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

[code]...

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?
