Values
| Value | Meaning |
|
lxCaseInsensitive |
Similar to loCaseInsensitive. Key fields and key values are matched without regard to the case. |
|
lxNearest |
LocateEx moves the cursor to a specific record in a dataset or to the first record in the dataset that is greater than the values specified in the KeyValues parameter. For this option to work correctly dataset should be sorted by the fields the search is performed in. If dataset is not sorted, the function may return a line that is not connected with the search condition. |
|
lxNext |
LocateEx searches from the current record. |
|
lxPartialCompare |
Similar to lxPartialKey, but the difference is that it can process value entries in any position. For example, 'HAM' would match both 'HAMM', 'HAMMER.', and also 'MR HAMMER'. |
|
lxPartialKey |
Similar to loPartialKey. Key values can include only a part of the matching key field value. For example, 'HAM' would match both 'HAMM' and 'HAMMER.', but not 'MR HAMMER'. |
|
lxUp |
LocateEx searches from the current record to the first record. |
