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 Index 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 the 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" subdirectory and it is set to 0x233.
