.NET 2010 Custom Control, Multiline String Property To Be Edited In The Designer?
Sep 21, 2010I'm writing a custom control and I want to add a "MessageText" property of type String:
<Browsable(True),
DefaultValue(""),
Category("CustomControls"),
[code]....
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

C# - Dynamically Changing Textbox AutoComplete List?
Jan 8, 2012My 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?

View 1 RepliesImplement The AutoComplete Functionality For Multiple Word In A Textbox?
Aug 4, 2010I 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

Populate A String Array To Use As An Autocomplete Source For A Textbox?
Jan 26, 2010Dim 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.
