HIMAGELIST TreeView_SetImageList(If you don't want to see the icons in the TreeView, you can use blank icons in the image list. However, this still leaves you with a big empty space. You can shrink this space by reducing the dimensions specified for the icons in the image list, but this has the unfortunate side effect of shrinking the size of the expando buttons correspondingly.
HWND hwndTV, // handle to treeview

TreeView controls refuse to display drag images unless if they have been assigned a normal image list. This can be done with the macro TreeView_SetImageList.
