Timothy,

Another way. In the cbo When: return ! empty(this.parent.mytextboa1.Value)

>If this can be solved. I have a combobox and a textbox and only one can be active at once. If the textbox has any input in it, the combobox should be dis-enabled so in the interactive exchange have:
>if len(thisform.somectls1.mytextbox1.value)>0
>thisform.somectls1.mycombobox2.enabled=.f.
>else
>thisform.somectls1.mycombobox2.enabled=.t.
>endi
>SO I test it by enter a little text in the txtbox and the combo becomes disabled like it's supposed to but when I backspace and remove the text from the said txtbox the combobox never becomes enabled.
