Hello Cetin
Thank you for your quick answer.

As a beginner i always try to subclass myclass from an existing class in the dialog.
New class myclass based on textbox,optiongroup,grid.....
Then i put some individual code to the events of myclass.

In the foxpro 7 dialog i can't find a baseclass header ?????

I also don't know, how to loop over all grid columns and change columnobjekts
(for example default textbox changing with mytextbox in all columns)
(or deleting default textbox in all columns)

??????????????????????????????????????????????????
for ....
this.columnxxx.currentcontrol = mytextbox
endfor
???????????????????????????????????????????????????

??????????????????????????????????????????????????
for ....
this.columnxxx.header = myheader ????
endfor
???????????????????????????????????????????????????

Best regards
Albert
