Hi everyone,

I've got an app that has a dPageFrame separating the various functions. One

of the pages is dedicated as a Help tab. I discovered the dHtmlBox widget

and thought this might be a good way to display a help page inside the app.

The problem is I've been trying to link the dHtmlBox widget to a locally

stored .htm file with no success. Here's what I've tried:

- Putting the file name inthe Source property. Then I figured out that

this was for displaying HTML source code.

- Putting the file name in the Page property. According to what I

understand from the documentation, this should have worked, but the widget

kept trying to find http://help.htm

- Setting the dHtmlBox's Page property to os.path.join(os.getcwd(),

'help.htm') when the form initializes. The problem I ran into doing it this

way was setting the RegID of the dHtmlBox. I don't know why, but in

ClassDesigner, I could only type numbers and the letter 'e' in the RegID

field of the Object Info window. I tried setting it manually in the .cdxml

file, but when I ran the code, I got the following error:

Traceback (most recent call last):

self.Form.HelpPage.Page = tmp

AttributeError: 'NoneType' object has no attribute 'HelpPage'

Obviously, the string I set as the RegID was 'HelpPage'. I am trying to

change the property with the following code:

def initProperties(self):

self.ShowStatusBar = False

tmp = os.path.join(os.getcwd(), 'help.htm')

print "Opening "+str(tmp)

self.Form.HelpPage.Page = os.path.join(os.getcwd(), 'help.htm')

The initProperties() method belongs to the dForm object. I'm not sure if

that's where I should have put it, but I was trying a few different places

and none of them seemed to make any more sense or work any better than this.

I'm sorry this is such a complicated problem, but any help you can offer

would be very appreciated. Oh, and by the way, I'm running Python 2.5 in

Win Vista Pro under revision 5270.

Thanks,

Mike M.
