ArgumentNullException

The parameters passed to this method are a null reference (Nothing in Visual Basic).

ArgumentException

SecurityException

The form template is not configured for Full Trust using the Security and Trust category of the Form Options dialog box.

This member can be accessed only by forms opened from a form template that has been configured to run with full trust using the Security and Trust category of the Form Options dialog box. This member requires full trust for the immediate caller and cannot be used by partially trusted code. For more information, see "Using Libraries from Partially Trusted Code" on MSDN.

This type or member can be accessed only from code running in forms opened in Microsoft InfoPath Filler.

In the following example, clicking the Button control gets the UserPermissionsCollection for the current form, adds and assigns a user to the Full Control access level, and sets an expiration date of two days from the current date.

public void CTRL1_Clicked(object sender, ClickedEventArgs e)
{
   string strExpirationDate = DateTime.Today.AddDays(2).ToString();
   DateTime dtExpirationDate = DateTime.Parse(strExpirationDate);

   this.Permission.UserPermissions.Add("someone@example.com", 
      PermissionType.FullControl, dtExpirationDate);
}
