- CreateHuge
- --- creates huge array of records from sample file. The records are in a
- type structure defined as "f_RecType".
- Sample.dat
- --- open the data file for reading
- --- get the size of the file
- --- determine how many records are in the file
- --- reset the file pointer to the start of the file
- --- create the global memory objecte
- --- make sure enough memory is available
- Insufficient memory to allocate array"
- --- get the address of the memory object
- --- read the data file into the memory objecte
- --- close the file
- --- unlock the memory object
- FillListBox
- --- get the array memory object selector
- this only needs to be done once in any form or routine.
- Note that memory is NOT locked. It doesn't need to be in
- in protected mode so the selector is valid even if the memory
- object gets moved. As this routine requires the Win 3.1 API
- calls, the app will always be running in protected mode.
- --- read records from array (f_NbrRecs is total # of records)=
- --- read a record from array into f_Rec record structure
- --- add record to listbox
