object

A SftBox object.

Part

Describes in which part of the combo box the potential OLE drag & drop operation has been detected.

Part	Value	Description
partSftBoxStatic	1	Static portion (not presently supported, reserved for future use)
partSftBoxEdit	2	Edit control portion
partSftBoxDropDown	3	Drop down portion

Button

Describes the button(s) that are pressed. The Button argument is a bit field with bits corresponding to the left button, right button and middle button. These bits correspond to the values shown below. The bits set indicate the button that caused the event.

Button	Value	Description
constSftBoxLeftButton	1	The left mouse button was pressed.
constSftBoxRightButton	2	The middle mouse button was pressed.
constSftBoxMiddleButton	4	The right mouse button was pressed.

Shift

Describes the state of the SHIFT, CONTROL and ALT keys. A bit is set if the key is down. The Shift argument is a bit field with bits corresponding to the SHIFT, CONTROL and ALT keys. It indicates the state of these keys. Some, all, or none of the bits can be set, indicating which of the keys are pressed.

Shift	Value	Description
constSftBoxShiftMask	1	The SHIFT key is down.
constSftBoxCtrlMask	2	The CONTROL key is down.
constSftBoxAltMask	4	The ALT key is down.

xPos

The x coordinate of the mouse cursor. The units used depend on the container (Visual Basic, Visual C++, etc.) and the coordinate system used.

yPos

The y coordinate of the mouse cursor. The units used depend on the container (Visual Basic, Visual C++, etc.) and the coordinate system used.

Comments

The DragStarting event occurs when the user is initiating an OLE drag & drop operation.

The DragStarting event occurs when the OLEDragMode property is set to OLEDragSftBoxManual and a potential drag & drop operation is detected.

The DragStarting event only occurs when a drag & drop operation is detected in the edit control portion or the drop down portion. The static portion cannot generate a DragStarting event.

If the combo box has an edit control portion (simple or drop down combo box), the user has clicked the mouse button on the currently selected text of the edit control portion. The Part parameter is set to partSftBoxEdit.

If the combo box has a drop down portion (drop down or drop down list combo box), the user has pressed the mouse button on an item and without releasing it, moved the cursor. The Part parameter is set to partSftBoxStatic or partSftBoxDropDown.

The application can start an OLE drag & drop operation by using the OLEDrag method.
