**UpdateBuffer, VIRTUAL**

{{blk2blue.jpg|blk2blue.jpg}}

The **UpdateBuffer **method copies corresponding data from the //queuefield //fields to the //filefield //fields specified by the **AddField** method for the currently selected browse item (using the value of **SELF.CurrentChoice**). Typically these are the browse list's queue buffer fields and the file buffer fields so that the file buffers match the currently selected browse list item.

**Implementation:**

Many of the BrowseClass methods call the UpdateBuffer method.

**Example:**

** IF FIELD() = ?FirstTab      !if first tab selected**

**  IF MyBrowse.SetSort(1,0)   !apply the first sort order**

**   MyBrowse.ResetThumbLimits !if sort changed, reset thumb limits**

**  END**

**  MyBrowse.UpdateBuffer      !update file buffer from selected item**

**  MyBrowse.UpdateResets      !update file buffer from reset fields**

** END**
