Parameters

Category
Type: System.String
Required. Represents the category name of the task item.

SubCategory
Type: System.String
Required. Represents the subcategory name of the task item.

Description
Type: System.String
Required. Describes the task item.

Priority
Type: EnvDTE.vsTaskPriority
Optional. A vsTaskPriority constant denoting the priority of the task item (high, medium, or low). If the value is vsTaskPriorityHigh, an exclamation point icon is displayed in the first column of the Task List. If the value is vsTaskPriorityMedium, nothing is displayed. If the value is vsTaskPriorityLow, a down arrow icon is displayed.

Icon
Type: System.Object
Optional. Determines the type of icon that represents the new task item. The setting must be either vsTaskIcon or an IPictureDisp.

Checkable
Type: System.Boolean
Optional. Indicates whether or not you want the task item to provide a checkbox that users can check to indicate the task is complete. The default value is false.

File
Type: System.String
Optional. Indicates the file or path associated with the new task item. The default value is an empty string (""), and if this is used, IsSettable(vsTaskListColumnFile) returns false. The file name can be a full path name, a relative path name, or simply a file name. Note that associating a file or path with an item does not necessarily mean that it will perform any actions.

Line
Type: System.Int32
Optional. Indicates the line in the source code associated with the new task item. The default value is 0, and if this is used, IsSettable(vsTaskListColumnLine) returns false. Note that associating a line number with an item does not necessarily mean that it will perform any actions.

CanUserDelete
Type: System.Boolean
Optional. Indicates whether a user can delete the new task item by pressing DELETE when the item is selected in the environment. The default value is true.

FlushItem
Type: System.Boolean
Optional. Indicates whether a new item is immediately visible in the Task List. When FlushItem is set to True, the Task List is updated immediately after Add is called. When FlushItem is set to false, the Task List is updated later after all updates are made. A false setting is used primarily to enhance performance when you are adding a large number of items at a time to the Task List. The default value is true.

Return Value

Type: EnvDTE.TaskItem
A TaskItem object.

Remarks

When adding bitmaps, the RGB color 0x0000FF00 (green) is transparent. All places in your picture that use this value will be transparent and the Task List will show through.

The width and height of bitmaps must be 16 x 16 pixels.

If using IPictureDisp, the PICTYPE argument must be set to either Icon or Bitmap. Settings of either Metafiles, Uninitialized, or None will not work correctly.

Examples

Sub TaskItemsAddExample1()
   Dim win As Window = DTE.Windows.Item(Constants.vsWindowKindTaskList)
   Dim TL As TaskList = win.Object
   Dim TLItem As TaskItem

   ' Add a couple of tasks to the Task List.
   TLItem = TL.TaskItems.Add(" ", " ", "Test task 1.", _
   vsTaskPriority.vsTaskPriorityHigh, vsTaskIcon.vsTaskIconUser, True, _
   "c:\temp.txt", 10, , )
   TLItem = TL.TaskItems.Add(" ", " ", "Test task 2.", _
   vsTaskPriority.vsTaskPriorityLow, vsTaskIcon.vsTaskIconComment, _
   False, "c:\temp2.txt", 20, , )
   ' List the total number of task list items after adding the new 
   ' task items.
   MsgBox("Task Item 1 description: " & TL.TaskItems.Item(2).Description)
   MsgBox("Total number of task items: " & TL.TaskItems.Count)

   ' Remove the second task item. The items list in reverse numeric order.
   MsgBox("Deleting the second task item")
   TL.TaskItems.Item(1).Delete()
   MsgBox("Total number of task items: " & TL.TaskItems.Count)
End Sub
