Thread ID: 257467 Mican Cagape .Net Conversion Hi,
My company has been using VFP and we have huge applications currently running (using DBF). My employer decided to shift into .Net which I have limited knowledge about it. Fortunately, my employer is willing to pay for my training.
I am seeking advice from any expert who could guide me through this plan. Do I need to change my programming language? Or is there a significant advantages
to change language?
Your response is highly appreciated.
_SCREEN vs As Top Level Form
Thread ID: 106360 Keith Gordijn _SCREEN vs As Top Level Form In all of my projects I have used an As Top Level Form for the main application form. Recently in reading the forums here and in other places, such as vfpsolutionexplorer, it appears that some of the big names in vfp programming (Doug Henning to name one) use the _SCREEN as the main app form.
So now I am wondering what are the advantages
of using the _SCREEN as the main form, ie. is it better when debugging? An As Top Level Form allows me to visually place objects and see what the form will look like without having to build and run the app.
Any insights for either style are most welcome and I am sure others will be interested in the pros

Chicao FUDG meets Tues. 13 Mar 2012
Thread ID: 339367 Randy Bosma Chicao FUDG meets Tues. 13 Mar 2012 Are you getting run ragged with multi tasking? Let VFP assist you!
At the March Meeting of the Chicago FoxPro Users and Developers Group Kevin Ragsdale will present "Easy Multi-Threading".
"For years, FoxPro developers have longed for multi-threading capabilities. Thankfully, several developers have found ways to provide multi-threaded capability in Visual FoxPro applications. Kevin tried every published method he knew of to create multi-threaded applications, but the easiest method (by far) was by using Christof's DMULT.DLL.
In this session, he'll show us;

* The advantages
(and disadvantages) of multi-threading
Choosing a database for foxPro
Thread ID: 161780 None None Choosing a database for foxPro Hi,
Working with VFP and C# as programming language, I would like to get some opinions which database to choose. What are the advantages
& disadvantages of
-Free Tables (dbf) in FoxPro
-FoxPro Database (dbc)
-free versions of Database Servers like IBM DB/2 or MS SQL Server
I occasionally heard of a corrupted file problem in FoxPro. Is this still true for recent versions of VFP?
How long can I rely on the support of VFP Technologies?
In our case we have to work with thick clients with a central database
Thanks in advance for your input.

CREATEOBJECT or lib call
Thread ID: 26563 Fred Shelhamer CREATEOBJECT or lib call Can someone tell me the advantages
/disadvantages to using CREATEOBJECT() versus visually adding the class lib to my form and referencing the procedure directly?

Data Access Techniques - VB NET
Thread ID: 214791 M. Akram Bhatti Data Access Techniques - VB NET Dear Experts,
In Visual Foxpro, when we open a table in shared access mode, any change committed to the underlying table automatically reflects to other users when they navigate to those modified records. But in Dot Net case is totally different. While going through the help and some articles, two major techniques have been used.
1. Disconnected (Data Sets, Data Tables, Data Relations, Data Adapters, XML Support)
2. Connected (Data Readers, DDL commands Support)
Both have advantages
and disadvantages it depends on the situation that which technique is being adopted. When we use DataSets, simply we have a local copy of data loaded
