Conclusion
This type of library is very useful for reviewing user input content on the website. It is far better than solutions such as replacement of Common keywords, forbidden submission of keywords, and manual review, this balances security and efficiency.

This morning, Wireshark packet capture software, Foxmail client, and Web client were used to test the security of mailbox login. The test was divided into three environments:
1. HTTP Login
After packet capture through Wireshark, it is found that all user names and passwords are submitted in plain text during HTTP Login. packet capture can easily obtain the user name and password, after logging on to a machine, the server generates a random session ID, namely, Sid. At this time, the user is on

If you have a slow hard disk, Visual Studio will block it while waiting for it to complete these read/write operations, which will greatly slow down your overall development experience.Some Suggestions on laptop hard drive
For most PC laptops, the general hard drive speed is 5400 rpm, which is very slow. If you want to buy a new notebook and plan to use Visual Studio on it, I strongly recommend that you get a hard drive of 7200rpm. You will be aware of the benef
Jacob, JCom is also used to call COM automation components. The running environment of JDK is also essential. JCom can also use Microsoft Office APIs to convert documents. Microsoft Office2007 or a later version is required, and Microsoft Save as PDF or XPS plug-in is still required for Office2007. In addition to calling Microsoft Office APIs to convert documents to PDF, JCom can also use the CreatePDF function of Adobe Acrobat to directly convert do

After this period of development experience, I personally feel that SSRS is still very useful. It is seamlessly integrated with SQL Server. layout is flexible and changeable, and the powerful functions of the Report Language, coupled with the affinity of Microsoft products, it brings a fresh user experience. However, SS

Haha, joke. It's not just a single Lambda expression. When acting as a method parameter and the ternary expression is not enough, this extension will be useful, you can define temporary variables and assign values to them, or create a method to solve such simple discriminant problems.

I mentioned this issue in a previous article. A bug 5095398 in swing will seriously affect the speed of netbeans. Recently, I heard a netizen say that his netbeans speed is very slow. I wonder if it is caused by this bug.
This bug occurs when the swing program is run in the notebook and the power is unplugged, it will find that the swing program is almost slow to use. The swing bug is probably: graphics performance degrades unacceptably when XPS lapt
pptfiles to lose weight, pptx files in version 2007 are much smaller than ppt files in version 2003.
● The PPT can be directly converted to PDF, XPS, and jpg formats, and some of the PPT pages can be published for various occasions.
● Effectively prevents document crashes. Once a document error occurs in version 2003, data that is not stored will be lost. Version 2007 tries its best to restore the status before the program is closed.
