[About The Guide]
Insert the contents of a file into a field
<nFieldPos> is the position of the field in the database file
<cSourceFile> is the name of the file containing the data to insert
into the specified field, including an optional drive, directory and
extension. See SetDefault() and SetPath() for file searching rules. No
default extension is assumed.
This function attempts to open <cSourceFile> in shared mode. If the file
does not exist, a runtime error is raised. If the file is successfully
opened, the operation proceeds. If access is denied because, for
example, another process has exclusive use of the file, NetErr() is set
to true (.T.).
Note: There are no restrictions on the size of <cSourceFile> except
that you must have enough disk space to make the copy.
DBFILEPUT() returns true (.T.) if successful; otherwise, it returns
DBFILEPUT() provides a mechanism for copying the contents of a file into
a field. By default, this function operates on the currently selected
work area. It can be made to operate on an unselected work area by
specifying it within an aliased expression.
DBFILEPUT() is used in conjunction with DBFILEGET() to transfer data
back and forth between files and database fields. You can use
DBFILEPUT() with a variety of field types, including graphics images,
word processor files, and printer fonts. These two functions are
excellent for creating databases of documents, graphics, sounds, etc.
Note: DBFieldInfo ( DBS_BLOB_TYPE, <nFieldPos> ) will return "C"
(string) for any memo field created using DBFILEPUT().
. This example imports information from a word processing
document into a field, then uses BLOBGet() to extract the first 25
characters of the field:
USE customer NEW VIA "DBFCDX"
DO WHILE .NOT. EOF()
GetPix( "Pix", Substr(LastName, 1, 4) + CustID)
FUNCTION GetPix(cPixField, cPixFile)
nPos := FieldPos(cPixField)
// Import the picture field into the indicated field
IF ! DBFILEPUT(nPos, cPixFile)
Alert("Import of picture " + cPixFile + ;
