The central server is considered absolutely safe, and several other database servers are provided for business access.[Business Process Introduction]You need to check and operate the credit line when handling a business. Various businesses frequently access the credit line. The general process is as follows:Business Server: When submitting documents, determine whether the cr

Everyone in the use of office2010 Excel tables found that the table pane will scroll with the mouse, so that the following will be confused with the corresponding title, this time just the Excel pane freeze will not scroll with the mouse, Just freeze the Excel pane in the Settings window. Oh, the following and small set together to see how to operate it.

changes to the SD node. However, when Abe appears, it means that Abd * cannot appear, and State SD cannot have new subnodes. Therefore, SD is determined and needs to be frozen. Do I need to ice the SB node? Of course, this is not the case. This is because new Sb subnodes, such as abf and ABG, may appear next time. This is why we need to calculate the public prefix, status nodes after the public prefix can be frozen, and these frozen nodes start from the tail. Therefore, the function of this ste
creation. To change the position, size, and color of the image, you only need to adjust the corresponding attributes. In fact, many of the properties that SVG specifically designed for processing various events are still tailored for animation. In SVG, there are several ways to implement animation:
1. Use SVG animation elements. This topic will be highlighted below.
2. Use scripts. Using DOM operations to start and control animations is already a mature technology, followed by a small example.
distribute the monitoring sites to different places. In fact, it is enough to use the nagios distributed method to do this. However, if you want to do an instant trigger emergency task, even if you click execute immediately on the nagios page, it will take a while to return all the results. Therefore, I chose to write a distributed asynchronous system.
The central controller script is as follows:

Excel, which implements the ability to lock the rows and columns of a table. When we are making an Excel table, if the number of columns, the number of rows is also more, once the scroll down, then the top of the header row followed by scrolling, in the processing of data often difficult to distinguish between the column data corresponding to the title, in fact, the use of the "Frozen pane" function can be a good solution to this problem. Locate the cursor in the next row of the header row (whic
There is a wide work report, as shown in. There is a title line at the top and the specific sales data below, when viewing data, you need to view the title bar while scrolling the data because the data volume is too large, so that you can clearly know the source of each data, that is, when you view any row of data, you can see rows 1st and 2 from column A to column J.

mentioned above, most mobile networks do not allow more than two concurrent connections. Therefore, you must set the queue size to 2 in a 3G network. MKNetworkKit automatically handles this for you. When the network is 3G/EDGE/GPRS, it will adjust the number of concurrency to 2. When the network is in the Wifi network, it is automatically adjusted to 6. When you load thumbnails from a remote server over a 3G network, this adjustment can bring great benefits.

object is set to non-extensible, the property can still be dynamically added to the prototype object, and the dynamically added property can still be inherited by the object.
Object. seal () and Object. freeze ()
Object. preventExtensions () can prevent dynamic addition of new properties to objects. In addition to this operation, there are two more stringent operations in JavaScript to protect objects: Object. seal () and Object.
the Object. preventExtensions () statement is the Object itself, and the prototype Object is not affected. If an object is set to non-extensible, the property can still be dynamically added to the prototype object, and the dynamically added property can still be inherited by the object.

Use the removed_from_stage and added_to_stage events to correctly freeze and unfreeze objects.To optimize your code, always freeze and unfreeze your objects. Freezing and unfreezing are important to all objects, but especially to display objects. Even if the Display object is no longer in the display list and is waiting for garbage collection, its code still occupies a large amount of CPU. For example, they

Customer requirements for the first few rows of table data or the first few columns to freeze, that is, when scrolling to keep these rows/columns do not move, through the Internet to find code, reference to the idea of existing code, to achieve any row, the column to freeze.
