Waiter, can send demo file + through the mail database you are not: duongfonuI@gmail.com /* <![CDATA[ */!function(){try{var t="currentScript"in document?document.currentScript:function(){for(var t=document.getElementsByTagName("script"),e=t.length;e--;)if(t[e].getAttribute("cf-hash"))return t[e]}();if(t&&t.previousSibling){var e,r,n,i,c=t.previousSibling,a=c.getAttribute("data-cfemail");if(a){for(e="",r=parseInt(a.substr(0,2),16),n=2;a.length-n;n =2)i=parseInt(a.substr(n,2),16)^r,e =String.fromCharCode(i);e=document.createTextNode(e),c.parentNode.replaceChild(e,c)}}}catch(u){}}();/* ]]> */
I thank !
Just updated his code link. You see the code in the link above to proceed. There are data that you create. ^^
Data can be displayed in the center of the table column is not?

Let me ask the owner why not add the update search function in ạ ? If it is about a few hundred lines long, then roll CHUAT search . You add the search function in that it helps me to be error nguyenvanquan7826 not ?
Search, you just SELECT * FROM table WHERE … but that's it.
But how are the heart of it blacked out the guy has found ạ
This is because your java code. For example, after you select the id return of records, and based on the id that you select the row with id that.
I do a text field to enter the code and then click the student on the search button if students found him yet, it will highlight it on the table straight to his work, then click it on him but without nguyenvanquan7826 help Kids are not sitting code without the whole morning? 🙁
How to delete multiple rows at once, sir you choose 3 which it only remove the last

but add, and delete functions remain normal run
This is the sql error, Your review see it make wrong Nearby, You do not have any place in the table columns or you forget where no?

Ukm 🙂 Tương tự nhé.
Chao bạn Quân. Minh đã học được rất nhiều từ Website của bạn. Bạn cho mình hỏi rằng nếu mình học về Java Swing thì có cơ hội việc làm không? Because I saw almost nobody uses Java Swing to write software both. We wish you respond to questions.
Welcome, of course, have the opportunity to do, however will be less than other segments because as you say, java swing their hours at work than. If you want a better chance, you should learn java java web or android nhé.
e want to make api to read data from the warehouse and put on website performance, e to do sir
