Detailed Description

You can create and write one XBase files with this class.
- Define the scheme
- Create the file
- Write the records
- Close the file
HXBaseFileWriter writer(new HCodepage852(),true);
writer.create("OUTPUT.DBF",3); //Opens the file
writer.setFieldStr("NAME","Big Joe");
writer.setFieldStr("NAME","Alice Newmann");

HXBaseFileWriter::HXBaseFileWriter ( HCodepageConvert conv,
bool  deletecobj = false 

Creates a XBase file writer object

convThe codepage converter of the class (put a HCodepageConvert descendant object according to the coding of the dbf file)
deletecobjif this parameter true the "conv" object is deleted if not used.

Member Function Documentation

int HXBaseFileWriter::appendRecord ( void  )

Append the current record buffer to the end of the file, and empty the buffer.

Definition at line 501 of file xbio.cpp.

int HXBaseFileWriter::close ( void  )

Closes the currently opened XBase file

Definition at line 426 of file xbio.cpp.

int HXBaseFileWriter::create ( QString  name,
int  version 

Creates the XBase file. You have to specify the schema before with the defineField() function. After calling this function the dbf is opened. (Do not call the open()!)

namethe path and name of the file
versionthe version of the file (eg: 3 or 4)

Definition at line 472 of file xbio.cpp.

void HXBaseFileWriter::defineField ( QString  name,
HXBaseFieldType  type,
int  length = 0,
int  nofdecimals = 0 

Define a field in the schema of XBase file. You can only use this function before create() ! The field specified with this function will be appended to the existing field list.

namethe name of the field (limited to 10 char. XBase limit)
typethe type of the field. See HXBaseFieldType enum
lengththe length of the field.
nofdecimalsthe number of decimals

Definition at line 438 of file xbio.cpp.

int HXBaseFileWriter::open ( QString  name)

Opens a XBase file to write. Do not call create() if you call this func!

namethe path and name of the file
0 if success

Definition at line 407 of file xbio.cpp.

int HXBaseFileWriter::resetRecord ( void  )

Empty the current record buffer.

Definition at line 493 of file xbio.cpp.

int HXBaseFileWriter::setFieldBool ( QString  fname,
bool  logical 

Set a value of a named field in the current record buffer

Definition at line 554 of file xbio.cpp.

int HXBaseFileWriter::setFieldDate ( QString  fname,
QDate  date 

Set a value of a named field in the current record buffer

Definition at line 565 of file xbio.cpp.

int HXBaseFileWriter::setFieldDecimal ( QString  fname,
long  decimal 

Set a value of a named field in the current record buffer

Definition at line 533 of file xbio.cpp.

int HXBaseFileWriter::setFieldFloat ( QString  fname,
double  val 

Set a value of a named field in the current record buffer

Definition at line 543 of file xbio.cpp.
