Example »

The following example creates a form, adds some controls and shows the form. Resize the form to see how the button is Docked to the bottom of the form.

PUBLIC oForm && so it remains reachable from FoxPro
LOCAL oControl
= SETCLRClassLibrary("system.windows.forms.dll",.T.) && Be sure the assembly is in the ClrClassLibrary path
oForm = CLRCreateObject("SYSTEM::Windows::Forms::Form")  &&Constructor without parameter
* Creates a Checkbox
oControl = CLRCreateObject("SYSTEM::Windows::Forms::CheckBox")
oControl.Text = "I was created from FoxPro"
oControl.AutoSize = .T.
oForm.Controls.Add(m.oControl)

* Creates a button
oControl = CLRCreateObject("SYSTEM::Windows::Forms::Button")
oControl.Text = "Click me"
oControl.AutoSize = .T.
oControl.Dock = 2
oControl.Top = m.oForm.Height - m.oControl.Height && at bottom
oControl.Parent = m.oForm && The parent
oForm.Show()

Remarks »

This function is modeled after the VFP's CREATEOBJECT.

To create a .NET Form:

= SETCLRClassLibrary("system.windows.forms.dll",.T.) && Be sure the assembly is in the ClrClassLibrary path
oForm = CLRCreateObject("SYSTEM::Windows::Forms::Form")  &&Constructor without parameter
oForm.Text = "Hello from VFP"
oForm.Show()
