Below is a comprehensive guide to essential VFP programming patterns, structured to help you build your own reference manual. 1. Basic Data Manipulation
If you are compiling these examples into a PDF, consider these tools:
VFP is a fully object-oriented language. You can define classes to create reusable components. visual foxpro programming examples pdf
VFP allows you to use SQL commands directly within the command window or programs. This is often faster than using native XBase commands like LOCATE or SEEK .
Use the TEXT...ENDTEXT command to include long blocks of SQL or documentation within your code for easy reading. Below is a comprehensive guide to essential VFP
* Create a new table CREATE TABLE Customer (CustID C(5), Name C(30), Joined D) * Add a new record INSERT INTO Customer (CustID, Name, Joined) VALUES ("C001", "Alice Smith", DATE()) * Browse the data BROWSE TITLE "Customer List" Use code with caution. 2. Working with SQL in VFP
SELECT * ; FROM Customer ; WHERE Joined >= {^2023-01-01} ; ORDER BY Name ; INTO CURSOR curRecentCustomers * Display results SELECT curRecentCustomers LIST Use code with caution. 3. Object-Oriented Programming (OOP) You can define classes to create reusable components
loMyForm = CREATEOBJECT("MyCustomForm") loMyForm.Show(1) DEFINE CLASS MyCustomForm AS Form Caption = "VFP Example Form" Width = 300 Height = 200 ADD OBJECT btnClose AS CommandButton WITH ; Top = 80, Left = 100, Height = 25, Caption = "Close" PROCEDURE btnClose.Click ThisForm.Release ENDPROC ENDDEFINE Use code with caution. 4. Automation and Interop
Check out VFPX on GitHub , a community-led effort to maintain and improve VFP tools.
One of Visual FoxPro's greatest strengths is COM Automation, which allows it to control other applications like Excel or Word.
