Const.PM_BlobSave
The Const.PM_BlobSave message is sent to all data items that have the Const.CHILDTYPE_Blob type set when BLOB object should be saved.
| Name | Description |
|---|---|
| wParam | Unused |
| lParam | Unused |
Application should return TRUE if the blob data was successfully saved, FALSE otherwise.
Upon receiving this message, applications should first call Binary_Object_API.Create_Or_Replace to create a blob header and receive a valid blob id. Applications may then save the blob data by inserting into the view Binary_Object_Data_Block.
This message is used by the framework class cPictureDataItem. Applications that do not use any other form of BLOBs do not need to implement this message.
