Function : Item (Field)
NSFItemAppend - Adds an item (field) to an open note using the item name.
#include <nsfnote.h> STATUS LNPUBLIC NSFItemAppend( NOTEHANDLE note_handle, WORD item_flags, const char far *item_name, WORD name_len, WORD item_type, const void far *item_value, DWORD value_len);
This function adds an item (field) to an open note. It does not update the Domino database file on disk. To write the modified note to the database file on disk, you must call NSFNoteUpdate after appending all items to the note.
NSFItemAppend is a flexible, low-level way to add an item to a note. You must specify, as input, the item name, the data, the data type, and the data length. The API also provides less flexible, higher-level functions such as NSFItemSetText for appending items of specific data types.
NSFItemAppend creates an item header and adds this item header to a queue associated with the open note. You may append any number of items to a note through repeated calls to NSFItemAppend. NSFItemAppend also allocates a block of memory to store the item value. It copies the number of bytes specified by value_len from the buffer specified by item_value into this memory block. This means that after NSFItemAppend has returned, your program may free the memory specified by item_value.
The data pointed to by item_value does not begin with the data type word. The format of the data pointed to by item_value depends on the data type. The reference manual entry for each data type specifies the format of the item value.
For each of the following data types, the data pointed to by item_value must be in Domino canonical format. Your program must convert the item value to Domino canonical Format before calling NSFItemAppend if (1) your program runs on a non-Intel architecture machine, and (2) item_type is one of the following data types:
TYPE_COMPOSITE TYPE_COLLATION TYPE_OBJECT TYPE_VIEW_FORMAT TYPE_ICON TYPE_SIGNATURE TYPE_SEAL TYPE_SEALDATA TYPE_SEAL_LIST TYPE_WORKSHEET_DATA TYPE_USERDATA
Use ODSWriteMemory() to convert item data from machine-specific (host) format to Domino canonical format before calling NSFItemAppend.
Parameters : Input : note_handle - The handle to the note that will receive this item.
item_flags - The flags that define the characteristics of this item. These flags are defined in ITEM_xxx and may be bitwise or'ed together for combined functionality.
item_name - The name of the item in the note. This name is equivalent to the field name when you design a form using the screen interface.
name_len - The length of item_name.
item_type - The type of data in this item. Item types are defined in TYPE_xxx.
item_value - A pointer to the value (excluding the data type word). If the API program is running on a non-Intel architecture system and item_type is one of the data types listed above, then the data pointed to by item_value must be in Domino canonical format.
value_len - The length of the item's value (excluding the data type word). The length must not exceed 64K bytes. If the ITEM_SUMMARY flag is set in item_flags, then value_len must not exceed 32K.
Output : (routine) - cReturn status from this call:
NOERROR - Successfully appended Item to the note.
ERR_xxx - Errors returned by lower level functions. Call to OSLoadString to interpret the error status as a string that you may display/log for the user.
Sample Usage :
/* Prepare to and then append the text list */ list_size = ListGetSize (list_ptr, prefix_flag); if (error_status = NSFItemAppend(note_handle,0, "Form", strlen("Form"), TYPE_TEXT, argv, (DWORD) strlen(argv))) goto Exit; if (error_status = NSFItemAppend(note_handle,ITEM_SUMMARY, ITEM_NAME, strlen(ITEM_NAME), TYPE_TEXT_LIST, list_ptr, (DWORD) list_size)) goto Exit;
