Choose the download you want. Download Summary:. Total Size: 0. Back Next. Microsoft recommends you install a download manager. Microsoft Download Manager. Manage all your internet downloads with this easy-to-use manager. It features a simple interface with many customizable options:.
Download multiple files at one time Download large files quickly and reliably Suspend active downloads and resume downloads that have failed.
Yes, install Microsoft Download Manager recommended No, thanks. What happens if I don't install a download manager? You can create a simple loop to iterate through the currently available networks using these functions.
The pseudo code looks like this:. In the example code that follows, you can see these structures defined as a C classes; this is done because a C class is always passed by reference, making the call to the methods simpler. Note that in the WSAStartup method, the second parameter doesn't have to be marked as an [out] parameter or use the ref keyword.
The second parameter is simply an instance of a WSAData class:. With these methods defined, you call them as shown in the following example code. This code snippet gets the name of each network and places it in a list:.
This is not overly efficient, and in later in this article, you will discover how to allocate only the amount of memory required.
This allows for the variation in the amount of data being received. Later in this article, you will discover how to use the extra data that is returned.
For the moment, only the name of the connected network is utilized. Your mobilized application should get a list of the currently connected networks when it first starts up.
The application can then enable or disable the features that require network access, along with other behavioral modifications the application should make based on connectivity, such as accessing a local data cache. You can then write the code that will change the application's behavior when the current network connections change.
In order to make the changes, your code must be notified of changes to the available networks. The following topic shows how to receive notifications when a change occurs to the currently connected networks. The previous code shows you how to determine the networks that are currently available.
You can then adjust your application to behave in an appropriate way. Of course, you will want to be notified of any changes to the state of network connectivity.
You do this by polling for the currently connected networks. One way to do this is to create a worker thread that rebuilds the list of currently connected networks, but there is a better way of doing this.
The WSANSPIoctl function is used to return immediately and provide information as to whether there has been a change to the connected networks. This method can be polled, and you can act upon any changes in the currently connected networks from within your code. You can use this in a worker thread that then calls a delegate method in your code.
The sample code that follows demonstrates this by creating an event that gets fired whenever there is a change in the network connections:. To stop the thread from running, this code call Abort on the thread. In your application, you may wish to call Interrupt and use an exception handler to catch a ThreadInterruptedException.
The NetworkChangedEventArgs used in the previous code is a simple class that contains an ArrayList of the networks that are currently connected. The NetworkMonitor method in the example code shown has an endless loop. In production code, you would want to use a thread synchronization flag to end the thread when the application is closing down. One of the issues to address when writing network awareness code is how to test the methods.
Manually, it is quite easy to pull the cable out of your PC and then plug it back in again. A good test technique is to have a secondary network connection through a USB adaptor.
You can then set this up so it is on your desk and you can easily unplug and plug it in to test your implementation of the methods discussed. Most modern applications require that there be some form of automated and unit testing.
It is recommended that you encapsulate the NLA components into a class. You can use the program to help diagnose a problem or to provide information to a tech support professional over the phone, for example.
Network Diagnostics enables you to set options for scanning your computer and the network connections. You can choose to scan the following actions:. You can also diagnose various categories in addition to the networking actions, including mail or news service, computer and operating system information, modems, network clients, and so on. You can save the options you checked so that the next time you use the Network Diagnostics program, you use the same options. Viewing the Local Area Connection status With the Status dialog box, you can view the speed of your connection, the length of the connection, your IP address, the subnet mask, the default gateway, and other information.
The Control Panel appears. Double-click Network Connections. The data may be useful to find data leaks, programs that phone home, or other network activity on the system; even if malicious actors download data from your PC to a remote address.
Very nice tool. I use Nsauditor Network Security Auditor. This is what the Internet was all about, bright people sharing amazing things with other like-minded people. I miss it. Perhaps to make it look shinier? Not really, this one offers more options. Perhaps you should wonder why people keep posting negative, aggressive comments for no apparent reason.
Processhacker, they were previously on Sourceforge but have moved to Github. The program does a bit more than just watching network traffic. Sure looks like a clone or outright copy of TCPView.
