CA_VariantSet1DArray
HRESULT CA_VariantSet1DArray (VARIANT *variant, unsigned int arrayType, size_t numberOfElements, const void *array);
Purpose
Creates a safe array from a 1D array and stores the safe array in a variant.
 |
Note Use CA_VariantClear to free the safe array stored in variant. |
Parameters
| Input | ||||
| Name | Type | Description | ||
| arrayType | unsigned int | Data type of array. arrayType can contain any of the fundamental data types for variants, safe arrays, and properties except CAVT_EMPTY, CAVT_NULL, and CAVT_OBJHANDLE. |
||
| numberOfElements | size_t | Number of elements in array. An error is returned if you pass a value greater than UINT_MAX. |
||
| array | const void * | 1D array that CA_VariantSet1DArray converts to a safe array. array can contain any one of the following data types: long, short, float, double, VBOOL, char* (NULL terminated string), unsigned char, BSTR, DATE, CURRENCY, LPUNKNOWN, LPDISPATCH, SCODE, and VARIANT.

| Output | ||||
| Name | Type | Description | ||
| variant | VARIANT | Variant to which CA_VariantSet1DArray assigns the safe array. | ||
Return Value
| Name | Type | Description |
| status | HRESULT | A value indicating whether an error occurred. Negative error codes indicate function failure. Error codes are defined in CVIversion\include\cviauto.h and <Program Files>\National Instruments\Shared\MSDTRedistributables\SDKHeaderFiles\8.1\winerror.h. The LabWindows/CVI ActiveX Library explicitly returns error codes. Other error codes in winerror.h are generated by ActiveX servers and passed on to you by the LabWindows/CVI ActiveX Library. You can use CA_GetAutomationErrorString to get the description of an error code or CA_DisplayErrorInfo to display the description of the error code. |
