PRB: ActiveX Control with DLL Extension Doesn't Download (174864)
The information in this article applies to:
This article was previously published under Q174864 SYMPTOMS
When an ActiveX control with an extension of .dll is placed on an HTML page
using the <OBJECT> tag and CODEBASE attribute, it may not download to the
client's machine:
<OBJECT ID="PolyCtl1" WIDTH=192 HEIGHT=192
CLASSID="CLSID:4CBBC676-507F-11D0-B98B-000000000000"
CODEBASE="POLYGON.DLL">
</OBJECT>
CAUSE
If the directory where the DLL resides is set up with Execute access in
Internet Service Manager, Internet Explorer will treat it as an ISAPI DLL
and attempt to execute it.
RESOLUTION
To resolve this problem, turn off Execute access for the directory in
Internet Service Manager. Another alternative is to rename the control from
.dll to .ocx. You can also create a CAB file, in which case the extension
of the file being downloaded would be .cab (CAB files are documented in the
ActiveX SDK and the Cabinet SDK).
STATUS
This behavior is by design.
