# ConnectModeEnum
Specifies the available permissions for modifying data in a [Connection](../../../ado/reference/ado-api/connection-object-ado.md), opening a [Record](../../../ado/reference/ado-api/record-object-ado.md), or specifying values for the [Mode](../../../ado/reference/ado-api/mode-property-ado.md) property of the **Record** and [Stream](../../../ado/reference/ado-api/stream-object-ado.md) objects.  
  
|Constant|Value|Description|  
|--------------|-----------|-----------------|  
|**adModeRead**|1|Indicates read-only permissions.|  
|**adModeReadWrite**|3|Indicates read/write permissions.|  
|**adModeRecursive**|0x400000|Used in conjunction with the other *\*ShareDeny\** values (**adModeShareDenyNone**, **adModeShareDenyWrite**, or **adModeShareDenyRead**) to propagate sharing restrictions to all sub-records of the current **Record**. It has no affect if the **Record** does not have any children. A run-time error is generated if it is used with **adModeShareDenyNone** only. However, it can be used with **adModeShareDenyNone** when combined with other values. For example, you can use "**adModeRead** Or **adModeShareDenyNone** Or **adModeRecursive**".|  
|**adModeShareDenyNone**|16|Allows others to open a connection with any permissions. Neither read nor write access can be denied to others.|  
|**adModeShareDenyRead**|4|Prevents others from opening a connection with read permissions.|  
|**adModeShareDenyWrite**|8|Prevents others from opening a connection with write permissions.|  
|**adModeShareExclusive**|12|Prevents others from opening a connection.|  
|**adModeUnknown**|0|Default. Indicates that the permissions have not yet been set or cannot be determined.|  
|**adModeWrite**|2|Indicates write-only permissions.|
