Google has found a solution for this:
Inserting a value in the upload control only clears the form's reset function, but the other values in the form are reset.
Since you can use the reset of the form to empty, there is a way: Create a temporary form, and then the need to empty the upload control to move into it, reset, then move back to the original location, and finally delete the created temporary form. JS Code:
Copy Code code as follows:
var Upload = {
Clear:function (ID) {

Forms are the basis for Windows applications. New generation of development tools Visual Basic.NET provides a more simple and rich way to design a form, and without resorting to complex and error-prone API functions, we can easily create multiple effects forms:
1, easy to make transparent forms
Vb. NET makes it easy to create a form that takes on transparency: all we have to do is set the Opacity property to a value between 0.0 (fully transparent) and 1.0 (completely opaque) in the form's Proper

Internal System Security
First, we will briefly introduce the directory structure of the MySQL database. After MySQL is installed and the mysql_db_install script is run, the data directory and database initialization will be established. If we use the MySQL source code package and the installation directory is/usr/local/mysql, the data directory is usually/usr/local/mysql/var. The database system is composed of a series of databases, each containing a series of database ta
In the above article, we learned how to use MySQL to learn how to install MongoDB. In this article, we will continue our learning journey and learn its data storage structure.
1. MySQL Data Storage Structure
Each MySQL database is stored in a folder with the same name as the database. the MySQL database files include the database files created by MySQL and the database files created by the storage engine used by MySQL.
If MySQL uses the MyISAM storage engine, the database file types include.
MySQL is installed and the mysql_db_install script is run, the data directory and database initialization will be established. If we use the MySQL source code package and the installation directory is/usr/local/MySQL, the data directory is usually/usr/local/MySQL/var. The database system is composed of a series of databases, each containing a series of database tables. MySQL creates a database directory in the data directory with the database name. Each database table uses the database table na
