Options for HTML Dialogs

The exported functions for creating HTML dialog boxes, and also two interface methods, all have a pchOptions argument in which the caller may pass a string to specify options for the dialog box’s appearance. The applicable functions and methods are:

ShowHTMLDialog and ShowModalDialog (which are effectively the same)
ShowHTMLDialogEx
ShowModelessHTMLDialog
ShowHTMLDialg method of IHostDialogHelper interface
showModalDialog method of IHTMLWindow2 interface
showModelessDialog method of IHTMLWindow3 interface

The options string has the same form as for the style attribute in an HTML tag or the body of a CSS selector. Thus, options are separated by semicolons, and each option is an attribute, a colon and a value. The following table lists the supported attributes and values. Microsoft’s documentation of the exported functions refers readers to the documentation of the showModalDialog method, which is here taken as definitive, so that anything not at least noted by Microsoft there is highlighted here.

border	thin or thick
center	no, off or 0; yes, on, 1 or parent; or desktop
dialogHeight	unit value
dialogHide	no, off or 0; yes, on, 1; or NotSet
dialogLeft	unit value
dialogTop	unit value
dialogWidth	unit value
edge	sunken or raised
FONT	style component
FONT-FAMILY	string
FONT-SIZE	unit value
FONT-STYLE	italic, oblique or normal; or can be empty
FONT-VARIANT	small-caps or normal; or can be empty
FONT-WEIGHT	100, 200, 300, 400, 500, 600, 700, 800, 900, normal, bold, bolder or lighter; or can be empty
maximize	no, off or 0; yes, on, 1; or NotSet
minimize	no, off or 0; yes, on, 1; or NotSet
resizable	no, off or 0; yes, on, 1; or NotSet
scroll	no, off or 0; yes, on, 1; or NotSet
status	no, off or 0; yes, on, 1; or NotSet
unadorned	no, off or 0; yes, on, 1; or NotSet

Note that maximize, minimize and resizable set whether Maximize, Minimize or Size are enabled on the dialog box’s system menu. Quite how one comes to be documented and the others not is just one of those silly little mysteries that endear Microsoft to every programmer.
