Tron | A sophisticated finite state machine framework for Java

Tkinter widgets that use grid geometry manager, will be set by sticky='' by default, and in this way it will be in the middle of the cell of the column. And the column width will be the width of the widget with greatest width in that column(by default). So if you want to align some widgets, then use stick='w' or any other side on all the required widgets. Or sticky='news' to make it fill the cell entirely.

Is it possible to run OpenZeppelin contracts on the Tron Network?

Yes. For example this token uses an OpenZeppelin implementation of ERC20.

This happens, because in:

The BigInteger class has a toHex() method. So you can get the hex value like this:

It looks like $addressH = $tron->toHex($address); references a local variable $tron within the totalUsers and totalTickets methods.

Try this instead:

There is an approach that may help help you in refactoring your code to have less duplicate codes.

You can create a class and add your logic in a method in that class, then send your data through that class and do your repetitive logic in there.

For example, for making $tron create a class MakeTron in anywhere you prefer

callValue - Amount of SUN transferred to the contract with this transaction. (1TRX = 1,000,000 SUN)

A word of warning: this style with dynamic SQL in SECURITY DEFINER functions can be elegant and convenient. But don't overuse it. Do not nest multiple levels of functions this way:

• The style is much more error prone than plain SQL.
• The context switch with SECURITY DEFINER has a price tag.
• Dynamic SQL with EXECUTE cannot save and reuse query plans.
• No "function inlining".
• And I'd rather not use it for big queries on big tables at all. The added sophistication can be a performance barrier. Like: parallelism is disabled for query plans this way.

That said, your function looks good, I see no way for SQL injection. format() is proven good to concatenate and quote values and identifiers for dynamic SQL. On the contrary, you might remove some redundancy to make it cheaper.

Function parameters offset__i and limit__i are integer. SQL injection is impossible through integer numbers, there is really no need to quote them (even though SQL allows quoted string constants for LIMIT and OFFSET). So just:

I have found the root cause. The problem is with their API documentation. Their Chinese version explains it perfectly, but I assume they are having some trouble translating it in English.

Essentially, this API is deprecated because it's not secure. To use this API, you have to run a Full Node yourself, then call this API on the full node server.
