[This documentation is preliminary and is subject to change.]

Sets or gets the height of the modal dialog window.

This property is not supported for Metro style apps using JavaScript.


HRESULT value = object.put_dialogHeight(VARIANT v);HRESULT value = object.get_dialogHeight(VARIANT* p);

Property values


the height of the dialog window.


The IHTMLDialog::dialogHeight property applies only to windows that are created by using the IHTMLWindow2::showModalDialog method and the IHTMLWindow3::showModelessDialog method.

When a script calls the IHTMLWindow2::showModalDialog method, it suspends execution until the modal dialog box is closed. As a result, the script cannot use the IHTMLDialog::dialogHeight property to change the appearance of the modal dialog box. To control the appearance of the modal dialog box, use script in the file loaded by the sURL parameter or use the value of the sFeatures parameter to specify the desired settings.

Although a user can manually adjust the height of a dialog box to a smaller value—provided the dialog box is resizable—the minimum IHTMLDialog::dialogHeight you can set using script is 100 pixels.

In Windows Internet Explorer 7, the IHTMLDialog::dialogHeight property returns the height of the content area and no longer includes the height of the frame.

The default unit of measure for dialogHeight and dialogWidth in Microsoft Internet Explorer 4.0 is the em; in Microsoft Internet Explorer 5 it is the pixel. The value can be an integer or floating-point number, followed by an absolute units designator (cm, mm, in, pt, or pc), or a relative units designator (em, ex, or px). For consistent results, specify the dialogHeight and dialogWidth in pixels when you design modal dialog boxes.
