    Variable not initialized?

    If the condition "if s<>#48 then" is never satisfied, then j is not initialized. immediately after begin, initialize the variable. I use inline var for this.
  2. Isn't it enough to just make it inaccessible?

    Check if selected row in DBGrid

    It seems to me that you are referring to the Master - detail link. That is handled differently. If it is something else so: the button bothers me a lot I would run the code every time I change a record but the code is time consuming... Which of these applies?

    Check if selected row in DBGrid

    I kind of don't understand your problem. What are you actually pursuing? If you have only one record then the active buttons in the Navigator will be Insert/New, Edit and Delete. This is to say that you can't rely on the cursor buttons. It is better to work with the attached DataSet. Either it has an active/selected record or it doesn't. If you have something else in mind, then describe it more precisely.

    TFrame versus SubForm

    This is interesting information regarding Frame. It's probably worth the effort to study it.

    TFrame versus SubForm

    Yes. I asked the question mainly out of curiosity. Thank you for all the answers I create a form and set its Parent to some component on the "base" form. I don't have any problems with this.

    TFrame versus SubForm

    HI, when I tried TFrame more than 20 years ago, I had problems. I was immediately recommended to use SubForm. At that time TFrame was very unreliable. The question is: has that changed? Is TFrame problem free?
  9. Please translate this into English. It's an English forum.

    A native VCL, and not Windows-based, TComboBox control.

    I will note that most programmers completely reject the "with" construct.
