**DROPID(** [//thread//] [, //control//] **)**

{{blk2blue.jpg|blk2blue.jpg}}

| **DROPID** | Returns matching host and target signatures on a successful drag-and-drop operation. |
| //thread// | The label of a numeric variable to receive the thread number of the target control. If the target control is in an external program, //thread// receives zero (0). |
| //control// | The label of a numeric variable to receive the field equate label of the target control. |

The **DROPID** procedure returns the matching host and target control signatures on a successful drag-and-drop operation (just as DRAGID does), or the specific string set by the SETDROPID procedure.

| **Return Data Type:** | STRING |

**Example:**

**DragDrop    PROCEDURE**

**Que1 QUEUE**

**      STRING(90)**

**     END**

**Que2 QUEUE**

**      STRING(90)**

**     END**

**WinOne WINDOW('Drag & Drop'),AT(10,10,240,320),SYSTEM,MDI**

**        !Drag but no drop:**

**        LIST,AT(12,0,200,80),USE(?List1),FROM(Que1),DRAGID('List1')**

**        !Allows drops from List1 or the Windows File Manager, but no drags:**

**        LIST,AT(12,120,200,80),USE(?List2),FROM(Que2),DROPID('List1','~FILE')**

**       END**

** CODE**

** OPEN(WinOne)**

** ACCEPT**

**  CASE EVENT()**

**  OF EVENT:Drag                  !When a drag event is attempted**

**   IF DRAGID()                   !check for success**

**    GET(Que1,CHOICE())**

**    SETDROPID(Que1)              !and setup info to pass**

**   END**

**  OF EVENT:Drop                  !When drop event is successful**

**   IF INSTRING(',',DROPID(),1,1) !Check for multiple files from File Manager**

**    Que2 = |                     !and only get first**

**    SUB(****DROPID****(),1,INSTRING(',',DROPID(),1,1)-1)**

**    ADD(Que2)                    !and add it to the queue**

**   ELSE**

**    Que2 = ****DROPID****()              !get dropped info, from List1 or File Manager**

**    ADD(Que2)                    !and add it to the queue**

**   END**

**  END**

** END**
