IMultiSelection.ToggleRange Method

< PreviousTopNext >

Automation:

void ToggleRange ( [in] ulong Offset, [in] ulong Size) ;

Native (C++):

HRESULT ToggleRange ( [in] unsigned __int64 Offset, [in] unsigned __int64 Size) ;

Parameters

OffsetStarting offsetSizeRange size

Return Value

S_OK or standard OLE error code.

Remarks

Current selection ranges are intersected with a specified range. Those portions of the specified range that fall onto gaps are appended to the selection, and those portions that fall to existing ranges, are subtracted from the selection. Complexity: linear-time, depending on the current selection configuration. Complexity of this method is not worse than that of IMultiSelection.AddRange and IMultiSelection.RemoveRange

Examples

Using ToggleRange method

C#Copy Code

// msel is initialized elsewhere and is currently empty
msel.ToggleRange(100, 50);  // selection: [100..150)
msel.ToggleRange(100, 10);  // selection: [110..150)
msel.ToggleRange(0, 10);  // selection: [0..10) U [110..150)
msel.ToggleRange(140, 20);  // selection: [0..10) U [110..140) U [150..160)
msel.ToggleRange(10, 100);  // selection: [0..140) U [150..160)
