**OLEDIRECTORY(** //list// , //flag// [, //bits// ]** )**

{{blk2blue.jpg|blk2blue.jpg}}

| **OLEDIRECTORY** | Gets a list of all installed OLE servers or OCX controls. |
| //list// | The label of the QUEUE structure to receive the list. |
| //flag// | An integer constant or variable that determines whether to get a list of OLE servers (//flag// = 0) or OCX controls (//flag// = 1). |
| //bits// | An integer constant or variable that determines whether to get a list of 16-bit or 32-bit OCX controls. If one (1), it returns 16-bit OCX controls. If two (2), it returns 32-bit OCX controls. If three (3), it returns both 16-bit and 32-bit OCX controls. If omitted or zero, 16-bit programs return 16-bit OCX controls and 32-bit programs return 32-bit OCX controls. |

//Note: With 16-bit support deprecated in this release, the 32-bit mode should be used exclusively.//

**OLEDIRECTORY **gets a list of all installed OLE servers or OCX controls and places it in the //list// QUEUE. The //list// QUEUE must be declared with the same structure as the OleQ QUEUE declaration in EQUATES.CLW:

**OleQ QUEUE,TYPE**

**Name CSTRING(64) !Name of the OLE Server application**

**CLSID CSTRING(64) !Unique identifier for the operating system**

**ProgID CSTRING(64) !Registry name, such as: Excel.Sheet.5**

**END**

**Example:**

**ResultQ QUEUE(OleQ).         !Declare ResultQ the same as OleQ QUEUE in EQUATES.CLW**

** CODE**

** OLEDIRECTORY(ResultQ,0)     !Get list of installed OLE Servers & put it in ResultQ**

**                             !then let the user pick one:**

** ?OleControl{PROP:Create} = SelectOleServer(ResultQ)**

**!User's OLE Server choice procedure:**

**SelectOleServer PROCEDURE(OleQ PickQ)**

**window WINDOW('Choose OLE Server'),AT(,,122,159),CENTER,SYSTEM,GRAY**

**        LIST,AT(11,8,100,120),USE(?List),HVSCROLL, |**

**         FORMAT('146L~Name~@s64@135L~CLSID~@s64@20L~ProgID~@s64@'),FROM(PickQ)**

**        BUTTON('Select'),AT(42,134),USE(?Select)**

**       END**

** CODE**

** OPEN(window)**

** SELECT(?List,1)**

** ACCEPT**

**  CASE ACCEPTED()**

**  OF ?Select**

**   GET(PickQ,CHOICE(?List))**

**   IF ERRORCODE() THEN STOP(ERROR()) END**

**   POST(EVENT:CloseWindow)**
