Properties

AutoScaleBaseDpi

Size: Gets or sets the DPI basis recorded for automatic scaling.

CreateParams

CreateParams: Gets native creation parameters, using a border without a caption for embedded fixed-border forms.

CultureInfo

CultureInfo: Gets or sets the culture used by the form.

Throws:

• ArgumentException A neutral culture is assigned.

IconName

String: Gets or sets the embedded resource name used to load the form icon.

NamedProperties

Methods

BeginUpdate()

Suspends form redraw while a batch of changes is made.

Calls nest and must be matched by EndUpdate. The call has no effect before a handle exists.

BringWindowToTop()

Brings this control to the front, or activates it when it is a top-level or MDI form.

Returns: SalBoolean. True if the translated control exists; otherwise, false.

CenterWindow()

Centers this window within its parent or, for a top-level form, its owner or screen working area.

Returns: SalBoolean. True when the translated control exists; otherwise, false.

A top-level form is constrained to the selected screen working area. A control without a parent is unchanged unless it is a top-level form.

ClearCursor(type)

Restores the default cursor for a role, using the I-beam for TextBox subclasses.

Parameter	Type	Description
type	SalNumber	The cursor role: Sys.CURSOR_Window, Sys.CURSOR_DragDrop, or Sys.CURSOR_DisableDrop.

Returns: SalBoolean. True if the cursor is assigned to a supported role; otherwise, false.

CreateForm()

Initializes scaling, creates the form handle, and completes SAL creation once.

Reentrant or already completed creation requests are ignored.

DefWndProc(m)

Dispatches unhandled messages to the MDI-child procedure when required, or to the base form procedure.

Parameter	Type	Description
m	Message	The message to process.

DestroyWindow()

Closes this window when it is a form, or disposes the control.

Returns: SalBoolean. True if the operation is accepted by the SAL window implementation; otherwise, false.

A true result reports that the close or disposal request was made; a form can apply its own closing behavior.

DisableWindow()

Disables input to this control, or clears editability for a table column.

Returns: SalBoolean. True if the operation is accepted by the SAL window implementation; otherwise, false.

Dispose(disposing)

Disposes the form while preserving owner lookup during destruction, then releases a custom icon.

Parameter	Type	Description
disposing	Boolean	True to release managed resources as well as native resources.

DrawMenuBar()

UpdateMainMenu applied to this form.

Returns: SalBoolean. The result returned by SalWindow.UpdateMainMenu.

EnableWindow()

Enables input to this control, or enables editing for a table column.

Returns: SalBoolean. True if the operation is accepted by the SAL window implementation; otherwise, false.

For text-box controls, this operation also clears the read-only setting.

Native disabled styles are also cleared. When needed, tab navigation is restored except for unchecked radio buttons.

Parameter	Type	Description
nReturn	SalNumber	The SAL dialog result.

Returns: SalBoolean. The result returned by SalWindow.EndDialog.
