Quick start

In under 5 minutes you will have your first .NET class running from VFP.

Step 1: Initialize FoxBridge

loBridge = NEWOBJECT("FoxBridge", "FoxBridge.prg")
? loBridge.Ping()   && "Pong" confirma que la DLL esta cargada

Step 2: Create your first .NET object

System.Text.StringBuilder is a .NET class that builds strings efficiently. It is the 'Hello World' of FoxBridge.

* Crear un StringBuilder con texto inicial
loSB = loBridge.Create("System.Text.StringBuilder", "Hola ")

* Llamar metodos encadenados
loSB.Append("mundo ")
loSB.Append("desde .NET!")

* Convertir a string VFP
lcResultado = loSB.ToString()
? lcResultado   && "Hola mundo desde .NET!"

* Ver cuantos caracteres tiene
? loSB.Length   && 22

* Liberar
loSB = .NULL.

Step 3: Work with generic collections

FoxBridge translates List<T> and Dictionary<K,V> to VFP proxies. Indexing is 1-based (like VFP).

* Crear una List<String>
loLista = loBridge.Create("List<String>")

* Agregar elementos
loLista.Add("Visual FoxPro")
loLista.Add("C#")
loLista.Add("F#")

? "Total:", loLista.Count()    && 3
? "Primero:", loLista.Item(1)  && "Visual FoxPro" (base-1)

* Recorrer la lista
For i = 1 to loLista.Count()
  ? loLista.Item(i)
Next

* Eliminar un elemento
loLista.Remove("F#")
? "Despues de Remove:", loLista.Count()   && 2

loLista = .NULL.

Step 4: Call static methods

Many .NET classes have static members (no instantiation needed). We use loBridge.Static() to access them.

* System.Math es una clase estatica (no se puede instanciar)
loMath = loBridge.Static("System.Math")

? loMath.Abs(-42)       && 42
? loMath.Sqrt(144)      && 12
? loMath.Max(10, 20)    && 20
? loMath.PI             && 3.14159...

* System.IO.File: leer y escribir archivos
loFile = loBridge.Static("System.IO.File")
loFile.WriteAllText("C:prueba.txt", "Hola desde FoxBridge")
? loFile.Exists("C:prueba.txt")   && .T.
? loFile.ReadAllText("C:prueba.txt")

loMath = .NULL.
loFile = .NULL.

Step 5: Load your own DLL

FoxBridge can load any .NET DLL you have compiled yourself.

* Cargar tu DLL compilada en .NET
llOk = loBridge.LoadAssembly("C:MiAppinMiLogica.dll")

IF llOk
    * Instanciar una clase de tu DLL
    loObj = loBridge.Create("MiEmpresa.MiLogica.Calculadora", 0.16)
    lnTotal = loObj.CalcularConIVA(1000.00)
    ? "Total con IVA:", lnTotal
    loObj = .NULL.
ELSE
    ? "Error:", loBridge.GetLastError()
ENDIF
