Enum LinkMode 

#[repr(i32)]
pub enum LinkMode {
    None = 0,
    Automatic = 1,
    Manual = 2,
    Notify = 3,
}

Determines the link mode of a control for DDE conversations. This is used with the Form control.

Reference

Variants

None = 0

No DDE interaction. No destination application can initiate a conversation with the source control as the topic, and no application can poke data to the control.

Automatic = 1

Allows any Label, PictureBox, or TextBox control on a form to supply data to any destination application that establishes a DDE conversation with the control. If such a link exists, Visual Basic automatically notifies the destination whenever the contents of a control are changed. In addition, a destination application can poke data to any Label, PictureBox, or TextBox control on the form.

Manual = 2

Allows any Label, PictureBox, or TextBox control on a form to supply data to any destination application that establishes a DDE conversation with the control. However, Visual Basic does not automatically notify the destination whenever the contents of a control are changed. In addition, a destination application can poke data to any Label, PictureBox, or TextBox control on the form.

Notify = 3

Allows any Label, PictureBox, or TextBox control on a form to supply data to any destination application that establishes a DDE conversation with the control. Visual Basic automatically notifies the destination whenever the contents of a control are changed. However, a destination application cannot poke data to any Label, PictureBox, or TextBox control on the form.
