| Gets the value of a field as a variant. |
| |
 |
VARIANT GetFieldVal (
enum eStockInfoFld eFieldID
) |
|
| |
| Parameters | | eFieldID | [in] Identifier of the field, e.g. stofQuantity (C++) or eStockInfoFld.stofQuantity (C# / VB.NET).
| |
| Remark: In VBS, this field identifier enumerations cannot be used! You should use GetFieldID to get a valid field identifier. |
| | | | Return value |
A VARIANT containing the value of the requested field.
Be aware that this can be a null-object in some cases, e.g. if the value of a system field (e.g. Crc1) is requested. | | | | Remarks |
 | You have to call GetFirstChange (to fill the stock changes file) before you can use this method, otherwise an exception will be thrown. |
