Огромное спасибо! Работает! Есть только один недостаток - если какое-либо поле NULL (не заполнено), то при вычислении максимума вернет NULL.
Попробуйте так

Проверьте, возможно в настройки кнопки Поиск вы добавили TableGrid в первый список "1. Выберите компоненты учавствующие в поиске"
Если не так, тогда пожалуйста приложите ваш проект, проверю.

Видимо для этой кнопки вы присвоили действие "Закрыть форму", чего не нужно было делать.
Сделать подтверждение при закрытии на системный значек к сожалению пока возможности нет.

Re: TableGrid Rows and Columns (5 replies, posted in General)

Hello,
Removing repeating data on rows looks excellent but the code is a bit complex.
Do you think this might be a tablegrid property in a future release or will it stay as a script?
TableGrid support this function with the ability to expand child records, but I need implement it to MVD.
Also, is it possible to add sub-totalling (like you can with grid footers but at change of non-repeating data) - see attached screenshot?
Sub-totalling is not supported, you can do it using report system.

1. You should delete sqlite.db file from your project.
2. Put PRAGMA key="password" to between begin end. in your script project.
example:
begin
SQLExecute('PRAGMA key = ''passphrase'';');
end.3. Save the project.
4. Copy your sqlite.dll to the project folder.
5. Run your project from the project folder. (if you run the project from MVD, your file sqlite.dll will be replaced original version)

Re: Random (9 replies, posted in Script)
The Random function generates random numbers. They can be floating point numbers in the range :
0 <= Number < 1.0
if you need random values from 0 to 99:
var
n: extended;
i: integer;
begin
n := Random*100; // with floating point
i := Trunc(Random*100); // int value5,373 2016-03-17 12:34:24
