Detecting changes of Controls

Hi there,

in my FormView-based application, i have to store the contents/the state of editcontrols, comboboxes and other controls in a database, if the contents of the control
has been changed by the user.
Is there a very common way to detect, if the contents of a control has been changed ??
I tried to overwrite the PreTranslateMessage(..) function, but i do not find a way to detect if for example a user drags a text in a Editfield....

so i would be very happy if someone could give me a hint for solving this problem.

Thanks in advance

Thomas.

Could you store the original values in OnCreate( ), and then compare them when you need to?

Hi.

You can check what kind of messages each control has by class wizard.
For example,
Edit box has EN_CHANGE and Listbox has LBN_SELCHANGE.

I just use EN_CHANGE to make the button enabled when I input something in editbox.
So check the content of each message in order to be satisfied with your desire.

Hope for help.
