Downloading a file using a custom indicator

Thanks, I had thought of that, but wanted to include the function within the indicator so I could distribute it as a standalone solution.

Thanks for the info. Managed to sort it with some code I found elsewhere. For information, it is as follows:

#property copyright "Integer"
#property link "for-good-letters@yandex.ru"

#import "wininet.dll"
#property show_inputs

#define INTERNET_FLAG_PRAGMA_NOCACHE 0x00000100

#import "wininet.dll"

int InternetOpenA(string sAgent, int lAccessType, string sProxyName = "", string sProxyBypass = "", int lFlags = 0);
int InternetOpenUrlA(int hInternetSession, string sUrl, string sHeaders = "", int lHeadersLength = 0, int lFlags = 0, int lContext = 0);
int InternetReadFile(int hFile, int& iBuffer[], int lNumBytesToRead, int& lNumberOfBytesRead[]);
int InternetCloseHandle(int hInet);

extern string url = "http://www...../.......csv?111565";
extern string FileName = "....csv";

int start()
{
int hInternetSession = InternetOpenA("Microsoft Internet Explorer",0,"","",0);
if(hInternetSession <= 0)
{
Print("Opening Internet FAILED...");
return(-1);
}
string temp;
int iBuffer[256];
int dwBytesRead[1];
int hURL = InternetOpenUrlA(hInternetSession, url,"",0,INTERNET_FLAG_PRAGMA_NOCACHE,0);
if(hURL >0)
{
int fh = FileOpen(FileName,FILE_BIN|FILE_WRITE);
if(fh>=0) {
while(True) {
if(!InternetReadFile(hURL, iBuffer, ArraySize(iBuffer)*4, dwBytesRead)) {
Alert("InternetReadFile Error!");
break;
}
if(dwBytesRead[0]==0) break;
for(int i=0; i<dwBytesRead[0]; i++) {
int byte = (iBuffer[i/4] >> ((i & 3)*8)) & 0xff;
FileWriteInteger(fh,byte,CHAR_VALUE);
}
}
FileClose(fh);
}
else Alert("Error opening file ",FileName);
InternetCloseHandle(hURL);
}
InternetCloseHandle(hInternetSession);
return(0);
}

Indicators run in the GUI thread. If your indicator takes time to download, the entire terminal will be hung.

Create a separate program, perhaps scheduled.
