C# :: Download Data From Memory Controller
Jul 11, 2014Using the C # programming language LED controller through which controls the array is connected to the controller via the RJ45 port. I already know the basics, I mean specifics, ie
Using the instructions and DLL included with the hardware, I want to read data from it, but I can not deal with it.
Model controller is "C-Power5200" and dll is "CP5200.dll".
I would like to:-pick the data-display-edit and - save in the controller.
To read the data I am using the function
CP5200_Net_Read (BYTE * pBuf, int nSize);
and to save
CP5200_Net_Write (const BYTE * pBuf, int nLength);
C# :: Program To Download YouTube Videos
Feb 2, 2015I want to build a program that can download youtube videos, but I don't know where to start.
I can obviously use IDM to download videos, but I want to learn what goes on in the backend so I can download them manually!
I currently know python, javacript, nodejs, can I use those languages?

Visual C++ :: Throttle Binary File Download Via WinHTTP Gives Unexpected Results
Nov 11, 2014My Windows service may download a binary update in the background using WinHTTP APIs. I'm using code similar to the one from the bottom of this MSDN page. For ease of access I'll copy if below:
Code:
DWORD dwSize = 0;
DWORD dwDownloaded = 0;
LPSTR pszOutBuffer;
BOOL bResults = FALSE;
HINTERNET hSession = NULL,
hConnect = NULL,
hRequest = NULL;
[Code] ....
The issue I'm experiencing is that while downloading, the code above "hogs" most of the bandwidth available on the client computer. My goal is to make it "throttle" itself on a configurable "bps" level, say at 50 kbps and not use any more bandwidth.
Someone suggested measuring my current download speed (in bps) and depending on the value make the thread "sleep" before calling WinHttpReadData again.
So the formula I'd use to calculate BPS is this:
BPS = (BytesDownloaded * 1000 * 8) / TimePassedInMilliseconds;
Then to convert to Mbps:
Mbps = BPS / (1024 * 1024);
And the waiting/sleep would be done as such:
Code:
DWORD DesiredBitsPerSec = 50 * 1000;//for 50 kbps
if(fBps > DesiredBitsPerSec) {
DWORD dwW = (DWORD)((fBps - DesiredBitsPerSec) * 1000) / DesiredBitsPerSec;
if(dwW > 0)
::Sleep(dwW);//Sleep to throttle the download speed to the one we need
}
So I implemented it into the code above but it didn't work -- the Sleep API would produce very strange delays. So I decided to add a little bit more tracking code to actually be able to see what BPS values I'm getting.
I created a small test project that is attached to this post to illustrate the issue. (It's hard to explain without running an example.)
For a test I began downloading a large binary file (Windows 10 MSI, off Microsoft's server) and at the same time had the Task Manager open on a Performance tab that was showing me the current network throughput. I made a screenshot:
But as you can see, the reading on the test program and the actual network BPS values differ greatly.
