Hello All!
Just Discovered something. I have a custom component which gives me a
Unstable message only at design time (form). Here's the code:
class SECTIONCOMBOBOX(parentObj, name) ;
of COMBOBOX(parentObj, name) custom
with (this)
height = 22
left = 287
top = 22
width = 210
metric = 6 // Pixels
speedTip = "Select a section"
sorted = true
style = 1 // DropDown
dropDownHeight = 132
value = ""
endwith
this.Query = New Query()
with this.Query
sql := "select distinct category from 'creg0009.dbf'"
active := true
endwith
this.dataSource = this.Query.rowset.fields["CATEGORY"]
endclass
If I wrap the query part in an OnOpen function everythings ok. Problem
with OnOpen is that you can see the combobox flicker a bit as it
intializes. It may be because I'm using the creg0009.dbf file at the
same time that the designer wants it.
