For example

AutoComplete Textbox With Support For Delimiter

Apr 6, 2011

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.

Textbox AutoComplete - Items From ArrayList

Mar 19, 2008

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)

C# - Dynamically Changing Textbox AutoComplete List?

Jan 8, 2012

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?

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.

AutoComplete Textbox - Start Again When User Hits Enter

Jan 15, 2012

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??

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?

Implement The AutoComplete Functionality For Multiple Word In A Textbox?

Aug 4, 2010

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?

Populate A String Array To Use As An Autocomplete Source For A Textbox?

Jan 26, 2010

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.

Restricted Textbox Code (Specifically, Building A Class Library With Code)?

I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

.Net AutoComplete NOT Based On First Character?

Dec 15, 2011

I have a combobox that is populated with movies with a number corresponding to where it is held in our archives ie. "451 How The Grinch Stole Christmas"What I would really like to do is have an autocomplete routine that would make it possible NOT to have autocomplete only work on the first character. As it stands, with Visual Studio's native autocomplete if my combobox is populated by:

Apple Smoothie
Banana Puree
Crayon Colors

[code]....

and I type "Pu" I will get only "Pure Energy" as an autocomplete result. I would like it so that typing "Pu" would return Pure Energy & Banana Puree.

.NET Fulltext Autocomplete In A Combobox?

Nov 2, 2011

I'm struggling to meet a demand from my supervisors.Basically there are places in our project where there is a big selection of options. The most concrete example is choosing a city in the world. The items are hundreds of thousands.Using standard winforms controls and properties, one can search through a list fast.The problem is that we're using a concatenation of city&district name for all the items. Essentially PREFIX autotomplete works but does not work as needed. The task is to filter and show items by any given string in any part of the item. Essentially a FULL TEXT search in the combobox.Does anyone have an idea about switching autocomplete sources in runtime relatively qiuckly and handling the suggest/suggestappend event?

Autocomplete A Combox From Dataset?

Oct 28, 2009

I have a couple of texbox and combobox controls that are bound to a dataset. I can scroll this with the a bindingnavigator. But I want to have the combobox do autocomplete from the dataset. For example, if i type a "D" in the combobox bound to the 'ClientName' column of the 'ClientInfo' table,i want the comcobox to display all (or maybe the top 20) names that start with a "D". If i then type an "E" I would like the list to show all names starting with "De" and so on.

I have tried to bind the 'autocompletesource' of the combobox to the 'ClientName' column, but that did not appear to do anything.I am reasonably experienced with VB .Net, but totally new to database and data centric applications.
