Why would you want to...
During the past few months, I have been contacted by two organizations in the Denver area looking to acquire FoxPro 2.6 for DOS and/or for Windows with distribution kits. These organizations had purchased VFP, but had a need to redistribute a 2.6 application they had purchased with some modifications. The problem was finding a copy of FPD/FPW 2.6.
The very real frustration now being experienced is that FoxPro 2.6 DOS and Windows environments are still needed and used by business. With the 2.6 product being out of production and not available from Microsoft, it makes acquiring it impossible at any price. The product is also generally not available on the ‘recycled software’ market.
SOLUTION: A short note to Robert Green, Product Manager, Developer Tools, generated the best possible answer for these two groups. He said, “The Professional versions of FoxPro 2.6 DOS and Windows should be available for downgrade from “Supplemental Parts.”
On 3-10-99, I did call Supplemental Parts (800-360-7561). They indicated that a VFP owner may indeed downgrade to FoxPro Windows andfrr FoxPrn DOS with proof of ownership of a VFP product (by supplying information
from
the product box, or the Assy-#’s from the VFP CD or diskettes.
The cost of the downgrade (diskettes only) is:
(1) FoxPro 2.6 Windows Downgrade: $51.96
+
5.00 s/h (includes distirbution Kit).
(2) FoxPro 2.6 DOS DownGrade: $15.00
+
5.00 s/h (includes distirbution Kit).
(3) A “sidegrade” is defined as owning the PC product and wanting the Macintosh product, or the reverse. A sidegrade is also available from Supplemental Parts.

On some occasions you might want to store files in your DBF in order to retrieve them later on. For example, you might want to store icons, bitmaps or waves in a DBF, so that nobody can change them, and retrieve them from your DBF at the time your application needs them. Well if that’s what you’re interested in, then this technical paper is for you.
Memo Files/Fields
The wonderful capabilities of the memo fields of Visual FoxPro make it possible to store any kind of data. Nobody’s astonished to be able to store pictures in memo fields or even objects in general fields. So why not storing
...
files ? That’s it! No matter what type of file... all kinds of files!
The only technical issue to address is to be able to transfer the content of a file to the memo field. But isn’t that easy? Isn’t a file simply a string, a big string sometimes I admit.
Reading A File And Placing
Its Content In A String
What we need here is to come up with a function that will read
the content of a file whose namc. is pa:sed as a parameter, and
that will return it to the calling process. In fact,,I would even prefer to get two parameters passed to this function : the name of the file to read, and the buffer in which I’ll place the content. The function will return a .T. or.F. value to indicate whetherthe reading was successful or not. The buffer should of course be passed by reference.
#define FO_READONLY 0
#define INVALID_HANDLE (-1)
#define FILEPOS_BEGIN 0
#define FILEPOS_cURRENT I
#define FILEPOS_END 2
FUNCTION CopyFileToVar( cFiIe,cBuffer
LOCAL IRetVaI
LOCAL nHandle
LOCAL nSize
lRetVal
=
FALSE && Function is not successful by default nHandle
=
INVALID_HANDLE && Invalid handle by default
&& If we can find this file
IF
(
FILE( cFile))
&& Open it in READ-ONLY mode
nHandle
=
FOPEN( cFile,FO_READONLY)
&& If we obtained a valid file handle
IF
(
nHandle
!
INVALID_HANDLE)
&& Get the length of the file now (needed by FREADO) nSize
=
FIL_len( nHandle)
&& Read the file
