ATTR_DATA_TYPE (Control)
| Type: | Control attribute |
| Description: | The data type of the control. When used on a table, it refers to the default state of new cells when ATTR_TABLE_MODE is set to VAL_GRID. Note: When you enter a number in scientific notation into numeric controls of type int64 or unsigned int64, LabWindows/CVI converts the number to a double and then to a 64-bit integer. This conversion may cause a loss of precision after 15 decimal digits. |
| Control Types: | Binary switches, list boxes, numerics, picture rings, rings, numeric slides, ring slides, tables, trees. |
| Data Type: | integer |
| Default Value: | VAL_DOUBLE (numerics/tables), VAL_INTEGER (binary switches/rings/list boxes/trees) |
| LabWindows/CVI Compatibility: |
LabWindows/CVI 3.0 and later |
