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

Programmatically Check Process CPU Percentage

Oct 1, 2009

I'm attempting to write an app that watching for process spikes. IE: Watch every active process and log the difference between initial and max values of cpu percentage (or load) of each process. The problem is that, as far as I can tell from the MSDN, the Process class doesn't contain any property that is even remotely equal to the true load of the process. For the time being I've written the code to watch the PagedMemorySize64 property, but the values that are being spit out appear to have no relevance to load.

To be clear, I don't need the actual load percentage (though it would be handy), all I need is a property that is directly related to load to show what processes 'spike' during the execution of my program.

My code as it stands (initialProcessCheck runs first, then processCheck runs every 1.5 seconds or so until other threads doing irrelavent tasks are finished, then computeDeltas is run):

Private Sub initialProcessCheck()
'Checks the current load on all active processes and stores as initial values
For Each intPID As Integer In ActiveProcessIDs
Dim CheckProcess As Process = Process.GetProcessById(intPID)

Opening A Menu And Putting The Cursor/selection On A Particular Item Programmatically?

Feb 3, 2011

In our application, the customer can work with different client projects/datasets. If there are more than a few client projects to choose from, we display them in a listbox to start with, and then it is easy to preselect the last dataset that the customer was working with. However, if there are only a few client projects, we show them as options in a menu instead (think "recent documents"). When the application starts, I would like the menu to be opened automatically and the most recently used client project selected. Is there a way to open the main menu and a submenu of a form and select/focus (but not actually click) an item programmatically?

The old way that we were doing this in VB6 was to use SendKeys to send keystrokes to the form to open the menu and then arrow-down far enough to get to the most recent project, but that is kind of unclean. Particularly, if the user starts our application and then tabs away quickly to work in a different application, the keystrokes may end up being processed by that application instead.

Programmatically Check To See If A Sheet Exists In Excel?

Nov 4, 2010

I was wondering if there is a way to programatically check and see if a sheet exsists in an excel workbook?

Basically what I am doing is checking if an excel document exists, opening it up and checking if the specified sheet exists. I am currently unaware as to how to check and see if the sheet exists.


I have been given some good code to make this work. All i am missing now is the correct imports.

I have searched and found this import :

Imports Tools = Microsoft.Office.Tools.Excel

But for some reason that is not recognized. Do I have to configure VS somehow to make it work? Or am I just using the wrong import?
