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??

I would like some info on how to do a procedure. In my program when a user hits the Edit Command button I would like for the program to display a popup Textbox where he/she can input data and store it. Then the data will be linked to the comments box, once the user hits the save button. Also the popup textbox disappears after the user is done entering the data.

When editing C# code in Visual Studio 2010, the ENTER key makes IntelliSense complete the current suggestion, without adding a new line. In VB.NET, the default IntelliSense behavior for the ENTER key is to add a new line after completing the current suggestion.
How can I configure IntelliSense to change the VB.NET behavior to the C# one?I already know that I could press TAB or SPACE, but out of habit I always end up hitting ENTER (and changing line).

Inside a multiline Text Box I want it so that when a user presses Ctrl AND Enter then a new line is entered. But, if they press Enter on it's own, then it acts like the Accept button on the Form. I believe this is how Facebook does it.
Ctrl+Enter=NewLine Enter=Accept

I started learning vb 2010 over the internet for about an a week and got stuck on this assignment that I got from the internet
1.Add one textbox so the user can enter a distance measured in feet. Add labels as needed.
2.Add a button control which when clicked is converts the feet to meters (1 foot = 0.3048 meters), accepting floating point values and preserving them (no integer conversions) and display the output as shown next. 1 Points
3.Display the conversion result using a MessageBox (not msgbox) using this format: x feet is y meters, where x is the value entered and y is the result of the conversion to meters with up to 2 decimal places only. Then show an extra line of "Would you like to start another distance conversion?" and make the No button the default in the message popup and display the question icon.
4. If the user chooses Yes, cleanup the controls as in the Reset button. 0.5 Point
5.If the user clicks no, ask in another MessageBox if the user wants to quit.
6.If the user chooses to quit, close the window, otherwise no action is required.

I may be doing this wrong but I want to call a sub when the user presses enter on a textbox. The sub then shows a window in dialog mode. When I close that window, the computer makes a ding sound. Why is that? Is there a better way for detecting enter being presses on a textbox and not getting that ding?
If e.KeyChar = vbCr Then
LookupItem()
End If

I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
If e.KeyCode = Keys.Enter Then

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)

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?
