Yesterday when I was trying to reopen the ClientForm.py, I started by simply
executing the ClassDesigner.py, as I did when first creating the form. It
seems to start out like a wizard; "Select the class to Create". I'd read
something in a msg here about creating a blank form and then opening the one
you really wanted to work with; that didn't work. But now I see that using
as you've outlined works great.
Re the execution problem, when I double click the hours project main.py, a
dos window opens and closes right away, that's all.
Then I reopened ClientForm.py in the class designer, and tried file/run to
see if that gave me more to chew on. It does pop up a dialog stating
Attribute Error 'NoneType' object has no attribute 'ClientBizobj'
I have this code in object dForm
def createBizobjs(self):
conn = self.Application.getConnectionByName("ConsultHours")
bizClient = self.Application.biz.ClientBizobj(conn)
self.addBizobj(bizClient)
Note, the tutorial screenshot shows DesForm, but the text says dform. I used
dform, seemed to be the only option. The cdxml files viewed in a text editor
does have designerClass="DesForm" in line 2.
I'll search here on the forums and will probably be able to solve this.
