Autocomplete In Textbox For List Of Names Separated By Semicolon?
Apr 4, 2011
What I am trying to do is allow the user to enter a list of authors in a textbox separated by semi colons. After each author is entered, followed by a semicolon, I would like the autocomplete to work on the next name and so on (e.g., Smith, John; Eastwood, Clint...). I can get the autocomplete to work in a textbox with one name, but cannot seem to figure out how to get it to work on a list of names in a text box.

My client wanted to have a textbox in the Customer form of the application, which offers the applicable endings to a started street name. He starts to type a street name and the textbox offers a list of streets which start with the char sequence he typed into the textbox. Textboxes have the AutoCompleteCustomSource property and even though a list of common street names will be longer than it could be pre-filled on start, I could just hit a database with a query, populate an AutoCompleteStringCollection and show that to the user.
Now here's the thing: If I make the list populate on every keypress/keydown whatever, the program crashes and throws an AccessViolationException. I've found out that that's because: The control is in the middle of showing the AutoComplete list when at the same time it is being modified, resulting in the crash. When you refresh the Autocomplete List, the control is recreated with new pointers. Keyboard and mouse events (KeyPress, MouseOver, MouseLeave, MouseHover) attempt to reference the old control's pointers which are now invalid in memory causing a memory access violation to occur.
The underlying AutoComplete implementation does not allow for changing the AutoComplete candidate list object once it has been set on a window. To allow changing the list, WinForms destroys the Edit control or ComboBox and recreates it. This causes an exception if the underlying control is destroyed while the AutoComplete window is still use it. I read about this on MSDN, their resolution: Do not modify the AutoComplete candidate list dynamically during key events. I know that you can do this by creating a custom control and such, but can it be done with just pure coding wizardry?

I have a text box with a list of entries for example:
Reference 1
Reference 2
Reference 3
[Code]....
I plan to read the string back into a the textbox later using the split() method and assign each to string to an array.

I'm trying to make the autocomplete work on a list of items entered into a textbox separated by semicolons. I have a list of authors the user can choose from and it autocompletes as they type the name no problem, but what I'd like to do is after the user types a name followed by a semicolon, the autocomplete works on the next name and so on.e.g., Smith, John; Eastwood, Clint?

Is there a built-in function in VB.NET which would take an array of strings and output a string of comma separated items?
Example: function( { "Sam","Jane","Bobby"} ) --> "Sam, Jane, Bobby"

I have a number of classes that all implement the same interface. e.g.
Public Class IncidentAsset
Implements IModelWithIdentity
Private _assetId As Int16
Private _otherAsset As String
Private _asset As Asset
[Code]...
Is there a better way of doing this in VB.NET using .NET 2.0?

I would like to maintain a list of all of the strings entered into a ComboBox across all uses of an application on a given PC, for use as the AutoCompleteSource for that ComboBox, i.e., I enter in "Fred" in the ComboBox, commit the data, close the application, reopen the application, reopen the ComboBox, type "F", receive the suggestion "Fred".Assuming I already have in place code to create and maintain such a list in memory and add new elements to it as they are entered into the ComboBox, etc., what do you suggest as the best way to save/load this data in between sessions?Possible complicating factors: This application will be deployed via OneClick deployment, and will search for updates online every time the application starts. I would prefer that if the application updates, the list still exists after the update has completed.

Now it seems like a really simple question and I may just be being thick, but what I'm trying to achieve is basically print an array to screen in the following format: Item 1, Item 2, Item 3, Item 4 Although I say to screen, as that was the best way I could describe it, I'm actually writing it to the page inside some Javascript. The way I'm currently going about writing it out is as follows:

I'm using String.Join to attempt to turn an array list into a string that is comma separated, such as "1,2,3,4". I can't seem to get the syntax working.
Here's what I'm trying:
Dim aryTest As New ArrayList()
aryTest.Add("1")
aryTest.Add("2")
aryTest.Add("3")

How can I go about doing this properly?

I've got a BindingSource for a DataSet. I'm fairly new to this whole binding business and databases, and it took me hours to figure out how to use BindingSource to get to an item, because the Row method was not included in the autocomplete. Not to confuse anyone, here's some sample code:[code]The code runs perfectly and does exactly what I want. My problem is the following: When I've typed in source.Item(0)., autocomplete does not display Row in the list. Is this perhaps not the best way to do what I'm doing? Is there a reason it's hidden? Is this a good coding practice to do so? The fact that is wasn't there took me lots of time Googling, so I'm trying to figure out whether it's a Visual Studio glitch or my own.

End Sub
How can i make this sub??

I am developing an appilcation which requires a text box with auto-complete/suggestions (drop down) for multiple words (seperated by a delimiter like space) like the tags text box here in SOF. E.g. I start typing 'app' it should show all words in the suggestions list starting with app, and when I enter a word and press space and start typing a new word it should show all suggestions for that part-word.

I develop an application in vb.net and mysql server for data storage. I have a problem in my database I have something like 5000 codes stored like code, description, quantity, price, firm. I have a function to extract all the codes from database , it takes about 4,4269 ms to extract all 5000 codes with description and everything... in an arraylist. When I want to put all codes from arraylist in a textbox autocomplete, it took about 2305,400 ms and I think this is a big problem the function to put in textbox autocomplete all the items from arraylist:
Code Snippet:
Public Sub PopuleazaTextBoxDinListaCoduri(ByVal txtbox As TextBox, ByVal list As ArrayList)
txtbox.AutoCompleteMode = AutoCompleteMode.SuggestAppend
txtbox.AutoCompleteSource = AutoCompleteSource.CustomSource
Dim valoare
For Each valoare In list
txtbox.AutoCompleteCustomSource.Add(valoare)
Next
end Sub
This is one item from arraylist extracted from database in this format :
code4993 ->description of code4993(3 buc X 234 lei)

I have an autocomplete textbox in vb.net. It is working fine, but now I need to pop up the window again when the user hits enter or double clicks. So far, I know that when the user hits enter, the keydown event raises with e.kecode = 13. I guess my code would go here. My problem is how do I tell autocomplete to start again after the user hits enter??

I have an autocomplete box doing a search in my database. The sql command removes special characters but the textbox does not display the results because the returned results contain those special ones.For example if i type in 1234 the sql server will return 1234 and 123-4 but the autocomplete box will only show 1234. Is there a way where i can get both to display?

I am using Visual Basic 2010 Express to develop my windows application.
I am developing an application wherein I need a functionality similar to the outlook email address.
In outlook, we are able to enter multiple email addresses in "To" address box. When typing first few chars of an email, the AutoComplete functionality displays the list of possible email addresses. Either we can select from the list or we can continue typing. As and when we type email addresses, the AutoComplete functionality shows the list of possible email addresses for every email address that we type in the textbox (if anything is there). I am trying to implement this functionality in my application
I found there is a AutoComplete functionality for textbox. below is the code
[Code]....
I know that the AutoComplete is only for one word and not for multiple.
But How to implement the AutoComplete functionality for multiple word in a textbox?

Dim dt As DataTable = MyClass.DatabaseRecordsetCall()
Dim str(dt.Rows.Count) As String
If dt IsNot Nothing AndAlso dt.Rows.Count > 0 Then For Each row As DataRow In dt.Rows
str.SetValue(row.Item(0).ToString, dt.Rows.IndexOf(row))
Next
End If
This is the code I am using to populate a string array to use as an autocomplete source for a textbox.The datatable has 17 rows in it. However, it creates the string array with a length of 18.Just an FYI, if you try to use an autocomplete source that contains a value = nothing, it will cause your application to crash.No, not cause an exception which could be dealt with, but a solid inexplicable, pull your hair out, scream and curse because you cannot figure it out crash. The microsoft message that comes up references the file browseui.dll.The above code as is, will generate an extra array value whose value WILL equal nothing and cause this crash to happen.
