I am trying to upload custom values to specific URL and get the result that is given from the web site.
The problem that is occurring is that I don't know how to simulate "press" the input type="button".
Is the value wrong or something
Here is the link(English version)
I use the Bulgarian version but that doesn't matter.
WebClient myWebClient = new WebClient();
myWebClient.Credentials = CredentialCache.DefaultCredentials;
myWebClient.Headers.Add(HttpRequestHeader.UserAgent, "anything");
myWebClient.Proxy = null;
[Code] ....
The problem is that I don't get result, that looks like this.

I am writing a program to auto login in a web site. Before making next attempt I have to wait for some time like some 10 seconds(it is configurable). But during waiting UI should not freeze. I wrote code something like this. Here event m_hEvent[1]) will be set by another thread after 10 seconds.The problem is UI still freezes some times!
while(1)
{
//m_hEvent[1] will be set by another thread after 10 seconds
dwRet = MsgWaitForMultipleObjects(1, &m_hEvent[1], FALSE, dwMilliseconds, QS_ALLINPUT);
ResetEvent(m_hEvent[1]);
[Code] ....

So I am awful when having to use data or .txt files. I believe my code is right, I just don't know how to upload the files. Here is the description of the assignment and the coding:
Process the input file containing latitude and longitude data of US cities in degree, minutes, and seconds. Output the processed information in decimal degrees.
a) Write a C++ program to read each line of the input file, store each data line in an array of structure, calculate the degrees in decimal for latitude and longitude, store these values in the corresponding structure and write the results to the output file by processing the array.
b) Use vectors or dynamic array to optimize memory usage. Specify the design choice in your main comment for the program.
c) Split the City and State and store it in two separate fields.
d) Search a city and find it in the array of structure and print out ALL the information on the screen.
#include <fstream>
#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
#include <algorithm>
using namespace std;
struct City

Using 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);

I 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?

My 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.

I was wondering if it's possible to push a button on a website programatically. Unfortunately the button link is invisible, otherwise I could simply use the URL it links to. So is there a way to do it in c++ and if so, how?

I'm successfully publishing an app to my website by publishing locally and then uploading the files but one of the options offered is to publish straight to the web site but I can't find anywhere to enter a user name and password for my web site. I could also do it with ftp but since the option is offered to publish directly to the web site I'd like to try that method. I'm using the Click Once method.

I'm trying to upload a file to a FTP server with curl. The problem is that I do not know what to do after I enter the passive mode and open the specified port. I tried to send data with curl_easy_send but it simply hangs.
bool Ftp::Upload(const char *local_fn,const char *remote_fn)
{
int ret;
string ip;
unsigned port;
SendCmd("TYPE I");
// Enter passive mode and get IP & port
if(pasv(ip,port)==false)
return false;
[Code]...
How to send file to the server. And I also suspect I should tell the file size to the server.
