Hi,
I am using a data control form. How can I cancel a new data, which was added by "APPEND BLANK"?

As far as know there isn't an "express" way for this. You have write code for DELETE the newly added record.

Re: Data Control Form
Hello Esgici,
I think using memory variable for each field and array for one to many will be a better choice.
Using this I can easily check for uniqueness of primary key and secondary keys.
This needs more coding from programmer's side, but this will work (I hope)
With best regards.

Re: Data Control Form
Hi,
I wrote a prototype of data entry cum selection form.
I am confused where to post the code. But as it is related to the topic "Data Control Form", I put it here.
Please tell me where to put it if I made a mistake.
Please send your suggestion

Hello MOL,
Thank you very much.
I didn't send those functions, because I thought the message would become very lengthy. I am sending them now ...

East or West HMG is the Best.
South or North HMG is worth.
