This is what I usually do. When we want a data entry form, I have two buttons viz., 'Save' and 'Cancel'. Standard shortcut keys like Ctrl+S and Escape can also be linked to call these action functions. If an user closes the window without pressing 'Save' that means 'Cancel' or pressing Escape.
Now, whatever be the data required in the form, the user is allowed to enter, navigate through the controls by keyboard or mouse. When he presses the 'Save' button or Ctrl+S, validation of all the controls are checked once and if all of them are 'OK', then the whole data set would be used/saved.
Suppose some fields are interdependent, say only after selecting the item they can enter quantity, there we can use onlostfocus. However, I don't use msginfo() or msgstop(). Instead I would use the status bar or a separate label with red color. This label can be made visible whenever required. By this way the whole focus of the window will not be lost anytime.
This is a typical data entry screen of a live application.

@rathinagiri,@apais:
your advice is appreciated, every question I asked and so far every question was answered, brought me forward.
@rathinagiri: I'm surprised that you use the german date format, India was longtime under British rule.

Ya. It is either dd/mm/yyyy or dd-mm-yyyy as you see it.

In the first post of this thread you find the source code of defining a window Form_1.
To keep my growing app more readable I wanted to define this window in a separate prg-file, of course without function main.
I removed ';' from line TITLE "Year/Month" ;
and removed 'MAIN' of window definition.
The compiler gives me a 'syntax error' at line TITLE 'Year/Month (without semicolon)
What is going wrong?

Hi Robert,
Do you want to change the title of the main form afterwards? In that case use: Form_name.TITLE := 'something'
In the main DEFINE WINDOW set title to "" (no title)
Not sure if this is what you want...
