Remarks
Warning HTAs can potentially expose the client machine to malicious script. HTAs, like .exe files have read/write access to the files and system registry on the client machine. Powerful executables can be produced and delivered quickly with a few short script statements. Use of HTAs is not recommended where security or the source of the file is questionable.You can create an HTA by saving an existing HTML page with an .hta extension. However, to set application window properties, such as those listed in the Members table, include the HTA:APPLICATION tag within the head element.
The HTA:APPLICATION element requires a closing tag.
<HTA:APPLICATION ... > ... </HTA:APPLICATION>Because the HTA:APPLICATION element is an empty tag, it can also be closed using the following shortcut.<HTA:APPLICATION ... />Note When using the shortcut, the forward slash must be preceded by a blank space.This element is not rendered.
This element requires a closing tag.
