I have made taken one textbox in form, in which i have written following logic in Got Focus event.
When i focus on that its automatically showing all the suggested name from database field.
Private Sub CustomerName_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles CustomerName.GotFocus
da = New SqlDataAdapter("Select CustomerName from CustomerMaster", myConnection)
da.Fill(ds, "CustomerMaster")
[Code]...
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.
how to set the Textbox autocomplete source to specific column in my datatable?how can i do that?
View 13 RepliesI have some code that calls to Active Directory and gets a list of users then adds them into a ComboBox.
I would like to extend this feature by allowing the combo box to autocomplete when a user starts to type.
Ive read a few articles but they seem to be based on data coming from SQL server but none on Active Directory. Could anyone assist by advising how i could go about this?
In Key Press Event i have put the logic of search in textbox, when i press enter key it will take the values from textbox and brings the data in DataGrid.In another event of GotFocus there is an logic of autocompletestring collection from Table.

I have a DataGridView with a TextBox column (DataGridViewTextBoxColumn). I already set the AutoCompleteDataSource to a list of string values. Now, the default behavior of the TextBox column is to ONLY show the AutoComplete ListBox when something is typed. Is there a way to show/drop that ListBox on the CellEnter event or as soon as a user highlights that cell?

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.
View 1 RepliesI 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 :

View 5 RepliesMy 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?

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.
View 8 RepliesI 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??
View 11 RepliesI 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 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 using LinqPad to learn Linq by querying the NetFlix OData source.Here is the query I got working which is awesome.[code].....
(Pardon all the comments...it is a testament to the fact I am experimenting and that I will change the query for various needs).There are two thing I cannot figure out.First.Let's say I only want to return the first 10 results.Second (and most importantly). I want to filter by a partial string of the genre.Each title contains a Genres collection. I want to show only Genres where the Name contains a certain string (like "Family").Even better filter using Titles where genre.name.contains "firstFilter" AND "secondFilter".Basically, I want to filter by genre(s) and I cannot figure out how to do it since Title contains its own Genres collection and I cannot figure out how to return only title that are in one or more genres of the collection.

I am trying to add numbers. So if there are 2 numbers in a listbox, theyare summed up. If there are 3 numbers in a listbox, they are summed up
[Code]...
What I'm trying to do is to count the number of items. Then I start my counter at 0. For each time the counter goes up, I add another row from the list box. and loops until my counter reaches the number of items in my listbox. I'm stuck intTotal. The only way I know of adding the totals is lstCosts.Items(0)+lstCosts.Items(1)+lstCosts.Items(3). But what if the user enters 4 numbers? I can't find a way around that. I think this should be a very simple question and I think only this line needs to be changed.
I'm in the process of creating my own version of the Combo Box as MS version does not give me the flexibility I need, this is work fine. I just had a little niggle
The List box contains/uses ObjectCollection to hold all its objects, but it does not have the facility to inform by the way of events that an item has been added etc.
If I inherited from this collection could I add the necessary code to make this happen, I have done this in my previous controls I�ve created when I wanted this facility.

View 8 RepliesCurrently, I have a listbox lstInventory where I have loaded some database information from a .mdb file. I am able to add new records, and they all display correctly.
Yet, I can't seem to retrieve or access any of the listbox items. (Not trying to reaccess database in here, yet). I am hoping to "Edit" an existing database record by matching it to the lstInventory's selecteditem property. Unfortunately, I am not able to retrieve anything (tried traditional CType(lstInventory.selecteditem.ToString, String) approach, as well as a debug.write approach (which I can't seem to display, even with a Listener-which is another issue in itself).
Furthermore, when I check the listbox.items.count property, it prints out as a "0" [using a messagebox.show()]
I have tried searching multiple forums, but found lots of "database into listbox" threads, and the MSDN website hasn't helped me yet. Do I need to know the collection's name (what would it's name be based on ?)? Or am I not converting the object into a printable/countable quantity?
