HRESULT get_type(
BSTR *p
);
Retrieves the type of intrinsic control represented by the given element object.
| Element | Possible Value | Description |
| INPUT | checkbox | Used for simple Boolean attributes or for attributes that can take multiple values at the same time. It is represented by a number of check box fields, each of which has the same name. Each selected check box generates a separate name/value pair in the submitted data, even if this results in duplicate names. The default value for check boxes is on. |
| file | A file upload element. | |
| hidden | No field is presented to the user, but the content of the field is sent with the submitted form. This value can be used to transmit state information about client/server interaction. | |
| image | An image field which you can click, causing the form to be immediately submitted. The coordinates of the selected point are measured in pixel units from the upper-left corner of the image, and are returned (along with the other contents of the form) in two name/value pairs. The x-coordinate is submitted under the name of the field with .x appended, and the y-coordinate is submitted under the name of the field with .y appended. Any value property is ignored. The image itself is specified by the SRC attribute, exactly as for the Image element. | |
| password | The same as the TEXT attribute, except that text is not displayed as the user enters it. | |
| radio | Used for attributes that accept a single value from a set of alternatives. Each radio-button field in the group should be given the same name. Only the selected radio button in the group generates a name/value pair in the submitted data. Radio buttons require an explicit value property. | |
| reset | reset is a button that when clicked resets the form's fields to their specified initial values. The label to be displayed on the button can be specified just as for the submit button. | |
| submit | submit is a button that when clicked submits the form. You can use the value attribute to provide a non-editable label to be displayed on the button. The default label is application-specific. If a submit button is clicked to submit the form, and that button has a name attribute specified, then that button contributes a name/value pair to the submitted data. Otherwise, a submit button makes no contribution to the submitted data. | |
| text | Used for a single-line text-entry field. Use in conjunction with the size and maxLength property. | |
| SELECT | select-multiple | Specifies a multiple-select list box. |
| select-one | Specifies a single-select list box. | |
| TEXTAREA | textarea | Used for multiple-line text-entry fields. Use in conjunction with the size and maxLength properties. |
HRESULT put_value(
BSTR v
);
Sets the default or "selected" value of the given control.
| Control type | Description |
| checkbox | The "selected" value. The control submits this value only if the user has selected the control. Otherwise, the control submits no value. |
| file | The value, a file name, typed by the user into the control. Unlike other controls, this value is read-only. |
| hidden | The control submits this value when the form is submitted. |
| OPTION | The "selected" value. The containing list box control submits this value only if the user has selected the option. |
| password | The default value. The control displays this value when it is first created and when the user clicks the reset button. |
| radio | The "selected" value. The control submits this value only if the user has selected the control. Otherwise, the control submits no value. |
| reset | The button label. If not set, the label defaults to "Reset". |
| submit | The button label. If not set, the label defaults to "Submit". |
| text | The default value. The control displays this value when it is first created and when the user clicks the reset button. |

HRESULT put_name(
BSTR v
);
Sets the name of the control, bookmark, or application.
The name is used to bind the value of the control when submitting a form. The NAME is not the value that is displayed for the button, reset, and submit objects. Submitting the form submits the internally stored value, not the one displayed.
JScript allows the name to be changed at run time. This does not change the name in the programming model, in the collection of elements, but does change the name used for submitting elements.

HRESULT get_name(
BSTR *p
);

The name is used to bind the value of the control when submitting a form. The NAME is not the value that is displayed for the button, reset, and submit objects. Submitting the form submits the internally stored value, not the one displayed.
