Based on the dialog box, the main window is a dialog box type, you can easily use the control, WYSIWYG programming, more convenient. single-document applications like Notepad are the basis for the development of file-processing software, except that each application processes only one document (compared to the multiple file).

This article describes how jQuery binds events to dynamically created elements. If you have any need, refer to the features that are frequently used on the front-end page before entering the topic: when you click the input box on the page, the text is automatically selected. It is easy to think of using the focus event of the input box, when the input box gets the focus, then call the select () method of jQuery. Okay, the idea is simple, and the logi

connected to a router, LAN is accessible, outside the network we want to set a forwarding rule, each router's settings are not the same, my is the polar route, set as follows: The rule is that when someone accesses your extranet IP, you can switch to the corresponding IP within the LAN. One thing to note here is that, like an extranet IP and a WAN port IP, if it's not the same, it's possible that you're connected to more than one router. And my is because the telecommunications broadband is no

The sequence created in oracle is the so-called serial number. It is automatically added each time it is obtained. It is generally used in places where the sequence is sorted by serial number.

Fixed repeated variable definitions when multiple files are created in Keil Extern is used in many places in the C/C ++ language. However, if you do not really understand its meaning, it will bring a lot of trouble to programming, let's explain it in detail. For small programs, there is usually only one C file and one head file. We usually define global variables directly in the C file and add int I Definitions before the program. If you want to de

Under normal circumstances, it is a little troublesome to publish a test version to the user to ask the device ID of the other party and add it to the developer certificate. If it is a jailbroken machine, you can use xcode to create an IPA file, and directly synchronize it with iTunes, which is much more convenient. Select iOS device as the running target.

During the architecture process today, I encountered the following problem: the single-built instance is gone! It was really strange that I thought about countless methods and did n tests all afternoon, but I couldn't find them. This is generally the case: In the initial stage of project startup, it is easy to initialize some option values in a single-created instance? Now, implementation is started, and it will be completed in a moment. It is normal
