DrgDragFiles - Example Code

This example calls the DrgDragFiles function to begin direct manipulation for a single file object, using the same source and target name, and determining the file type based on the file's type EA.

#define INCL_WINSTDDRAG /* Direct Manipulation (Drag) Functions */
#define INCL_WININPUT   /* Window Input Functions               */
#include <os2.h>

BOOL     fSuccess;      /* Indicate success or failure          */
HWND     Hwnd;          /* Handle of calling window             */
PSZ      pFiles[1];     /* The names of the files to be dragged */
PSZ      pTypes[1];     /* The file types of the files to be    */
                        /* dragged                              */
PSZ      pTargets[1];   /* The target file names                */
HPOINTER hptrDrag;      /* Icon to display during drag          */

pFiles[0] = "FILENAME.EXT";  /* Copy file name to string array  */
pTargets[0] = NULL;     /* Use source name as target name       */
pTypes[0] = NULL;       /* Query type EA to determine file type */

fSuccess = DrgDragFiles(Hwnd, pFiles, pTypes, pTargets, 1,
                        hptrDrag, VK_BUTTON2, FALSE, 0L);
