Copy the code out of the method to a plain text file. Delete all leading and trailing spaces. Save the file as plain text and close the file. Then, in the Properties window, right-click the method and choose "Reset to default". Then open the text file, copy the code from it, and paste it back into the method. That usually works for me, but if it doesn't: 2. A. If it's a program class, delete the .fxp files related to it and its superclasses and recompile them. 2. B. If it's an .scx or a .vcx class, BACK UP the file and delete the contents of the Objcode field in the subclass, and recompile the object. Ken Dibble www.stic-cil.org

If the method has a subclass, *anything* in the subclassed method will cause the superclasses code not to run. I often find I've left a whitespace character -- tab, space or carriage return -- in the subclass. Ctrl-A, Ctrl-X clears them out. As an alternative, add: SET STEP ON DODEFAULT to the subclass and see if *that* executes.

Subclassed Methods Not Getting Executed
by Gene Wirchenko 02 Mar '16

02 Mar '16

Dear Vixens and Reynards: I have a new program that has had a bug reported on it that a table was not getting closed. I have a routine that runs after most menu choices that checks that no tables are still open and reports if any are. OK, maybe I missed it. No, there is code in the exit method that closes the table. Maybe, there is an error in the test. Insert a set step on. The method never gets executed! I have used this way for years for other forms, but in this form, the exit method just does not get executed. I have scanned the source code for odd characters. There are none. What might I be overlooking? Sincerely, Gene Wirchenko

A great book. I looked, and, yes, it is on the shelf about five feet away. I should reread it. [snip] Sincerely, Gene Wirchenko

>However, when I did find - was a small book called FoxTales: Behind >the Scenes at Fox Software. A great book. I loved the part about how the reporting engine was a forbidding tangle of spaghetti code that everybody was afraid to touch. Ken Dibble www.stic-cil.org

SQL Server Transactions
by Chris Davis 02 Mar '16

02 Mar '16

Hi All If I start a SQL transaction and append records via a VFP View, issue a table update but don't COMMIT the transaction are these records available from another machine? If they are how could I know that they have been appended in a transaction that may well end up getting rolled back? Thanks Chris. Chris Davis Acton Gate Systems Limited We are moving!

Using an expression for the RowSource of a textbox
by Joe Yoder 02 Mar '16

02 Mar '16

I am almost certain that I have successfully used an expression as the field to display in a listbox but I can't figure out the syntax I used or which RowSourceType needs to be selected. Can someone help me out? Thanks in advance, Joe --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html ---

Suggestions for closing out simple applications?
by Joe Yoder 02 Mar '16

02 Mar '16

I have never used a framework and often just execute my stuff in the VFP environment. When I do an exe for others to use I am never sure what commands to include to shut things down. Sometimes I end up with applications that can't be shut down without killing them in Task Manager and sometimes I end up with code that forces me to re-execute "Modify Project" after a run after build. My Simple applications has a main.prg that calls a main form which calls two other modal forms. Each form shuts down with a thisform.release. The main.prg file looks like this: USE Simple DO FORM Main READ events CLEAR events CLEAR PROGRAM RELEASE all Right now this setup forces me to goto Program|Cancel before I get the command window back after a run. Some input from a pro would save me a lot of trial and error!

A Curious Find: FoxTales
by Kurt Wendt 01 Mar '16

01 Mar '16

I was almost thinking this should be marked as OT or NF - since its Not Technical - and its Not about VFP coding... So - a couple of months ago, as you know - I was looking for a book here at my office regarding Office Automation. Since, in our office - there were a number of bookcases with lots of books on them. And, since ALL the original systems were written in FoxPro - it so happens that they had a LOT of FoxPro books. Now - I didn't find the specific Automation book I was looking for. However, when I did find - was a small book called FoxTales: Behind the Scenes at Fox Software. And, in the past I have read some true stories about technology - like "Mind of a New Machine" and "iWoz". So - I figured this would be interesting. And, indeed - Kerry Nietz is doing a great job in telling of the story. Am at the point in the book where the product was renamed from FireFox to FoxPro - and Kerry is relaying his work in creating the Report Writer (originally based upon a 3rd party program - which they then integrated into FoxPro for DOS). I'm finding the book quite entertaining - and figured others in this forum might also find it interesting! Kurt Wendt Consultant (Soon to be Employee...)
