virtual L_INT LAnnotation::Lock(pLockKey, uFlags=0)
Locks the annotation object with the specified key.
Character string containing the key used to lock the annotation object.
Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR (|). The following are valid values:
|0||Process only the specified object.|
|ANNFLAG_SELECTED||[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnContainer::GetSelectItems() and LAnnotation::SetSelected() functions.|
|ANNFLAG_NOTTHIS||[0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.|
|ANNFLAG_RECURSE||[0x0008] Process objects within a container, and within any subcontainers, down to any level.|
|ANNFLAG_NOTCONTAINER||[0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.|
|ANNFLAG_NOINVALIDATE||[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
Only unlocked objects can be locked. If an object is already locked, it will stay locked with its original key. You must pass the same key to LAnnotation::Unlock to unlock the object(s).
An object must be unlocked in order to change that object in automated mode.
Redact objects must be unlocked to be restored (unrealized). Refer to LAnnContainer::Unrealize.
This function applies to multiple and selected objects based on values of the uFlags parameter.
L_INT LAnnotation_LockExample(LAnnotation& LeadAnn)
L_INT nRet = 0 ;
// lock all selected items in the container
nRet = LeadAnn.Lock(TEXT("MyKey"), ANNFLAG_RECURSE | ANNFLAG_SELECTED);
if (nRet == SUCCESS)
nRet = LeadAnn.ShowLockedIcon( TRUE, ANNFLAG_RECURSE);
if(nRet != SUCCESS)
MessageBox(NULL, TEXT("All objects will be locked ..."), TEXT("Notice"),MB_OK);
