VS 2010 : Programmatically Check Item In CheckedListBox?

Jun 12, 2011

Having some issue trying to programmatically check items in a CheckedListBox.What i am trying to achieve:

1. Pull Staffnames from database

2. Separate each staff member via delimiter

3. checked = true for each item in StaffCHKlist where staffnames = existing StaffChKlist item

i have had a few goes, but cant seem to achieve, this is where i am currently at:

Dim sl As String = ds.Tables("Consignment").Rows(0).Item("StaffName")
Dim tokens As String()
tokens = sl.Split(",")


which errors with:

"List that this enumerator is bound to has been modified. An enumerator can only be used if the list does not change."

I have been trying to understand, would programmatically checking an item in a checkedlistbox be classified as list change?

CheckedListBox With One Bolded Item?

Mar 28, 2011

I have an application that uses a treeview and a checkedlistbox to allow a user to navigate and enable/disable printers on their computer. Everything works great.One of the program requirements is that the user interface must visually indicate which printer is the users default. The obvious best way to do this is by changing the font of the item in the listbox that matches the users default printer. From my research, it seems that I will have to subclass the checklistbox and add the drawmode property to the new control. I've got no idea how to do this with a checkbox and make it actually work!

.net - Programmatically Close A TFS Work Item

May 17, 2010

I am attempting to import items from a legacy issue tracking system stored in an Excel sheet into Team Foundation Server. I loop through the rows of the Excel file successfully, and I can create new work items, but they are always in the Proposed state. If I attempt to change the state to Closed, then call the Validate method for the work item, I receive a validation error on the State property - InvalidListValue{4}.

Dim MyProj As Project = store.Projects("MyProject")
Dim WIT As WorkItemType = MyProj.WorkItemTypes("Task")
Dim WorkItem As WorkItem = WIT.NewWorkItem()


this is a CMMI task that I am trying to create and close. I wonder if I'm trying to skip over certain activities required by CMMI
