I. Create a database connection in the class
It is best to make namespaceUsing system. Data. sqlclient;/// /// Summary description for DB/// ///Namespace vote{Public class DB{Public static sqlconnection createconnection (){Sqlconnection con = new sqlconnection ("Server = gyykf; database = vote; uid = sa; Pwd = sa ;");Return con;}}}
Ii. Bind a database
First open the database:Sqlconnection con = class1.createconnection ();Con. open ();Then use the command to extract the data:For example:Sqlcomman

14: The benefits of a system designed with the concept of SDR for network operation:
L devices of various communication systems share hardware platforms, saving data centers and reducing investment
L only software upgrade is required during technology evolution, and the construction of new technologies and standard networks is greatly accelerated

When a stored procedure is executed, the stored procedure created in the database is handed over to the interface layer and sent to the Dal layer for processing. As long as commandtype = storedprodure is set, the database can process the stored procedure.

Gnuradio can also run on Windows, and when installing Gnuradio, a series of PowerShell scripts are automatically downloaded to build in the source. It then relies on a 64-bit native binary file, packaged with Visual Studio 2015, into an. msi.If you want to know more about it, see here.The MSI package includes:
Device support: UHD, RTL-SDR, Hackrf, Airspy, Bladerf, OSMOSDR, FCD

CitationI recently had a strong interest in software-defined radio technology (SDR), and I was interested in one of the popular SDR platforms (HACKRF), which received a range of frequencies between 1MHz ~6ghz (wider). There is also a need to mention an interesting and useful attack method, that is, to re-send the attack, of course, it can be understood to record a simple signal, and then broadcast it. I wil
