I get an error when I try to use the WePO control.

There are several items you need to be aware of in trying to troubleshoot WēPO.

1. For each version of WēPO, there is an unique class identifier, clsid, that is called by the web page. This object, the referenced version number and the codebase referencing a specific .CAB or .OCX file, all combine to make sure you are running the correct ActiveX component. They must match up or your ActiveX component will not be called. Everytime you receive a new version of WēPO, be sure to check our web site to make sure you are using the correct classid.

<OBJECT classid="clsid:659D3554-54CD-46BC-B0F1-D88C4CCFD10C"
   codebase="http://www.mysite.com/controls/printwizocx.cab#version=2,7,0,0"
....    

2. The web browser needs to be able to print to some printer. This is usually not an issue, but we have seen a few Windows and Internet Explorer installs come back with no default printer. Make sure you have a default printer designated at the Windows level and that Internet Explorer can see this printer under the File menu and Print...

3. The file being rerferenced by the "mainurl" parameter must be available to be fetched by the web browser. Have your web administrator check permissions if you suspect problems here.

<OBJECT classid="clsid:659D3554-54CD-46BC-B0F1-D88C4CCFD10C"
   codebase="http://www.mysite.com/controls/printwizocx.cab#version=2,7,0,0"

<param name="mainurl" value="http://www.mysite.com/reports/myreport.txt">
<param name="caption" value="Print">
</OBJECT>

4. Lastly, any personal firewall security may cause a problem, as well as certain settings within Internet Explorer's Options. Check to be sure yopur security settings a) allow a download and install of the ActiveX, and b) they do not prevent ActiveX from running.
