Forms :: Find A Method Of Looping Through A Listbox And Retrieving The Index Number And Values?
Mar 24, 2010I need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.

VS2010 - Cannot Find Method On Object Instance
Nov 19, 2010Basically, I've got this plugin-based application I've used all the time in VS2008 flawlessly. In my current project (VS2010 by the way) I wrote a plugin for the application and whenever I try to use an instance of a particular class (in an external dll) from my plugin, I get an error.
I tried watching the instance and I got the message:
"Cannot find the method on the object instance."
in the watch window. This has never happened before! I also found that some of the extension methods in the plugin does not work.

View 4 RepliesForms :: Listbox Faster Method For Selecting All
Dec 1, 2010I have a listbox control that has a selection mode "MultiSimple" (I've also tried MultiExtended). I also have a button that uses this code to select all the items in the list:
Dim i As Integer
For i = 0 To ListBox1.Items.Count - 1
ListBox1.SetSelected(i, True)
Next i
It works ok but the problem is that it's very slow. I have cases where there are 60 000 items in the listbox, and it takes forever to select them all. Is there any function that would select all at once (Just like ListBox1.ClearSelected() unselects all instantly)?
Implement The .Find Method When Binding A BindingSource To LINQ (IEnumerable) Result?
Mar 15, 2008I'm binding a DataGridView to a BindingSource to a LINQ IEnumerable, I found that the BindingSource.Find method throws an exception because .Find isn't implemented in IEnumerable (and the BindingSource just passes the call to it's DataSource). I need to use BindingSource.Find to select/highlight a particular row in the DataGridView.
Is there a feasable way to extend my DataContext to support this behavior w/o breaking anything else? I expected to find the code out there already, but I've searched exaustively with no luck.Without it, I cannot "move" the BindingSource using .Position and that's a pretty common use of the BindingSource I think.
Random File Access - Using Binary Sort Method To Find Record
Dec 24, 2011I have a flat file that is sorted by account number. I am migrating an application that was in vb6 to .Net. The application uses Random file access and uses a binary sort method to find a record.
Here is the code
Do While (low < high Or low = high) And (f = 0) 'Checking for an account match
middle = (low + high) / 2
FileGet(FileNum, Record, middle)
If Account < Trim(Mid(Record.Data, Byte1Start, Byte1Len)) Then
[Code] .....
From reading up on this in .Net it seems that using the Binary Reader seek method would be the alternative to using old vb6 random access code. The problem is the Binary Reader Seek method goes by Byte position instead of record number. How to convert my code to use a binary reader.
