Syntax

Retrieving the number of dropped files Hide the details

<Result> = ExplorerRetrieve(<Message>)

<Result>: Integer

Number of selected files.

<Message>: System integer

First parameter of the WM_DROPFILES message (returned by the explorer to the WINDEV window or control), which means _EVE.wParam.

Retrieving the name of the dropped files one by one Hide the details

<Result> = ExplorerRetrieve(<Message> , <Number>)

<Result>: Character string

Name and path of the dropped file.

<Message>: System integer

First parameter of the WM_DROPFILES message (returned by the explorer to the WINDEV window or control), which means _EVE.wParam.

<Number>: Integer

Subscript of file whose name must be retrieved.

Remarks

When a "Drag and Drop" is performed between the explorer and a WINDEV window (or control), the explorer sends the WM_DROPFILES message to the relevant target. The first parameter of this message (_EVE.wParam) used in ExplorerRetrieve returns the content of the "Drag and Drop" operation (number and name of selected files).

Remarks:

The number and the name of the files selected in the explorer cannot be retrieved if no "Drag and Drop" operation is performed between the explorer and a WINDEV window.
The WM_DROPFILES constant is defined in the Winconst.wl file supplied in the "Personal\External" sub-directory and it is set to 0x233.
