Define a binary name in a worksheet and assign a block of data to it

static BOOL DefineBinaryNameW(
   const wchar_t* pszName,
   void* pData,
   size_t cbData
static BOOL DefineBinaryNameW(
   const wchar_t* pszWorkbook,
   const wchar_t* pszWorksheet,
   const wchar_t* pszName,
   void* pData,
   size_t cbData



The name of the invisible range to add to the worksheet. The name must conform to Excel range name rules.


A pointer to the data buffer containing the data which will be assigned to the BinaryName.


The number of bytes in the data buffer.


Name of target workbook.


Name of target sheet.

Return Value

The function returns TRUE if the name is defined successfully, or FALSE if the operation fails.


Binary names are invisible Excel named ranges, accessible only to the add-in programmer, not to the user. They differ from visible ranges in that you cannot us them for Excel data types, only for buffers of binary data.

Binary names are held in worksheets, and are unique at worksheet level. However, there may be multiple instances of a binary name in a workbook (as many as there are worksheets in the book).

The first form of the function acts on the active sheet of the active workbook.

The second form acts on the requested sheet. In order to do so, the active workbook and sheet are changed if required, and then changed back again after the action is complete.
