Drag a file between the resource manager window and the control

Dragging a file from the control to the resource manager for copying is a convenient function.

There are two ways to implement this function:

1. Use System. Windows. Forms. Control. dodragdrop (New dataobject (dataformats. filedrop, strfiles), dragdropeffects. Copy ),Note:Strfiles must be a string array of all file paths (including file names ).String ArrayCannot be a string.

2. Use the dodragdrop function of a control, such as gridcontrol1.dodragdrop (New dataobject (dataformats. filedrop, strfiles) and dragdropeffects. copy ).

Drag the files in the Resource Manager to the control for storage, which is much simpler and ready-made on the Internet.CodeYou only need to respond to the dragdrop event of the control and then obtain the dragged file for upload.
