DataExport/DLL Interface
DataExport/DLL provides a simple, uniform API for output of more
than 40 data formats. This API allows you to query the DLL for
supported formats, create a new file, output data and close the
file with only a few function calls.
Querying the DLL for Supported Formats
The DataExport/DLL interface provides two functions which allow you
to query the component for the number and types of formats it currently
supports. These functions are intended for dynamic construction
of dialogue boxes and other communication with your program.
- DXGetNumTypes
- Returns the number of supported output types
- DXEnumTypes
- Returns output type information for a File Type, including
format name, file extension, type of file format and whether a
Sheet or Table name is required
Cell-by-Cell Output Methods
There are ten API methods used in a Cell-by-Cell output implementation.
These functions allow you to open a file, write data to it and
close the file:
- DXInitTrans
- Initialize an output file
- DXDefData
- Define a data format for each column/field
- DXPutInt
- Write a 2 byte signed integer to buffer
- DXPutLong
- Write a 4 byte signed integer to buffer
- DXPutSingle
- Write a 4 byte single precision IEEE Real to buffer
- DXPutDouble
- Write a 8 byte double precision IEEE Real to buffer
- DXPutString
- Write a zero delimited string to buffer
- DXWriteBuffer
- Write buffer to output file
- DXClearBuffer
- Clear data from buffer
- DXCloseFile
- Close output file
File-Based Translation Functions
There is only a single method for initialization of a File-Based
Translation. This function is similar to the command line call of DataImport:
- DXLaunchEngine
- Run translation with specified parameters
