Tests whether a Field has a null-value. A field has a null-value after calling VpeClearTplFields or after explicitly assigning a null-value to a Field by either calling VpeSetFieldToNull or VpeSetTplFieldToNull.
int VpeGetFieldIsNull(
VpeHandle hField
)
VpeHandle hField
Field Handle
Returns:
Value |
Description |
True |
the field has a null-value |
False |
the field has not a null-value |
Remarks:
The Template Object itself offers simple methods to access a Field's value directly, i.e. without retrieving a Field Object first. See VpeGetTplFieldIsNull.
