MoveFindFirst Method

Description:

Searches the Data Set associated with the currently open image for the first Tag of the Group Number specified by GroupNum. When this Tag is found, the Data Element becomes the Current Data Element.

The LevelOp parameter tells the method how to move when it comes to an SQ. Set it to one of the two following constants:

MED_DCM_MOVE_LEVEL_FIXED: This setting tells the method to move only within the same level as the previous Current DE. Any SQs and all of their Data Elements will be skipped over. If you are in an SQ you can only move within the SQ.
MED_DCM_MOVE_LEVEL_FLOAT: This setting tells the method to move up or down as needed to get to the next DE. If the next DE is an SQ the Current DE moves down into it. At the end of the SQ the Current DE moves back to the lower levels (for example, from Level 2 to Level 1).
