I am writing an application that configures the drives on a machine and launches a Server 2003 install.

I wanted to be able to provide status messages to the user via popup windows. When I use the app within XP or 2003, it works great, but when I run it in WinPE I get a "Class not registered" error when I try to execute Window.Open.

Has anyone used HTA files to create a user interface within WinPE?


Regards,

Jim

Could you please post the part of the code, Windows PE just lacks of some the security models that Windows XP has and that is normally causing this kind of error when using certain function in HTA pages.

Did you add the OPTIONAL Components?
HTA will not work unless you have added these components.

On your WinPE OPK cd go to the WINPE dir and run the "wscript BUILDOPTIONALCOMPONENTS.VBS /H"

Yes I installed the optional components. The rest of the HTA application is working fine. As a matter of fact I can do a Window.showModalDialog, but I can't do a Window.showModelessDialog or a Window.Open.


There is too much code to post, but here is the function that creates my popup status:

Function DisplayMessage (sMessage)
SET oStatusWindow = Window.open("","mywindow","location=0,status=0,scrollbars=0,width=200,height=200")
oStatusWindow.document.writeln "<HEAD><TITLE>Please wait</TITLE></HEAD><BODY>"
oStatusWindow.document.write "<CENTER><FONT SIZE=5>" & sMessage & "</FONT></CENTER>"
oStatusWindow.document.writeln "</BODY>"
SET DisplayMessage = oStatusWindow
End Function

Thanks,

-Jim

Also... If you are using PE 2004 or 2005.... Disable the Firewall.
I have heard of some weird things happening when it is enabled.

Are you uisng an custom DLL librarys?
Are they registered?
Do you have VB Runtimes added to he the styetm32 Directory?

Use Dependency walker to show you what dll's and exe's are associated with the file you are trying to run. Make sure you use F7 to run it and get the entire picture.

I'm not using VB only VBScript and HTA.

I've never used this. I will look into it. Will it work with an HTA app or only for EXEs?


Thanks,

Did you ever get this resolved? I'm just starting on something just like this, and could use the info.

Thanks
Did you RTFM?
