Downloading data via WinInet - c++

Question

And so there is a code, that can download data with size not higher than 1024*100 bytes. Code brought from https://rsdn.org/article/inet/inetapi.xml.
As far as I understand, InternetReadFile after every call should move on the read characters count, or it's sensless, because it'll return the same data. I red, that there is a function,that moves reading start pointer. Have I to use it?
HINTERNET hInternetSession;
HINTERNET hURL;
char cBuffer[1024*100]; // I'm only going to access 1K of info.
BOOL bResult;
DWORD dwBytesRead;
// Make internet connection.
hInternetSession = InternetOpen(
L"tes", // agent
INTERNET_OPEN_TYPE_PRECONFIG, // access
NULL, NULL, 0); // defaults
// Make connection to desired page.
hURL = InternetOpenUrl(
hInternetSession, // session handle
L"https://www.google.com.ua/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png", // URL to access
NULL, 0, 0, 0); // defaults
// Read page into memory buffer.
while(bResult = InternetReadFile(
hURL, // handle to URL
(LPSTR)cBuffer, // pointer to buffer
(DWORD)1024 * 100, // size of buffer
&dwBytesRead)==TRUE&&dwBytesRead>0) // pointer to var to hold return value
// Close down connections.
InternetCloseHandle(hURL);
InternetCloseHandle(hInternetSession);
DWORD dwTemp;
HANDLE hFile = CreateFile(L"googlelogo_color_272x92dp.png", GENERIC_WRITE, 0, NULL,
CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
if (INVALID_HANDLE_VALUE == hFile) {
return 0;
}
WriteFile(hFile, cBuffer, sizeof(cBuffer), &dwTemp, NULL);
Issue: I can't read more than 1024*1024 bytes, program crashes, when creates char[1024*1024]

Here is a complete program. Thanks to #RbMm
#include <windows.h>
#include <wininet.h>
#pragma comment(lib,"wininet")
int main(int argc, char* argv[])
{
HINTERNET hInternetSession;
HINTERNET hURL;
// I'm only going to access 1K of info.
BOOL bResult;
DWORD dwBytesRead=1;
// Make internet connection.
hInternetSession = InternetOpen(
L"tes", // agent
INTERNET_OPEN_TYPE_PRECONFIG, // access
NULL, NULL, 0); // defaults
// Make connection to desired page.
hURL = InternetOpenUrl(
hInternetSession, // session handle
L"http://wallpapers-images.ru/1920x1080/nature/wallpapers/wallpapers-nature-1.jpg", // URL to access
NULL, 0, 0, 0); // defaults
// Read page into memory buffer.
char buf[1024];
DWORD dwTemp;
HANDLE hFile = CreateFile(L"пример.jpg", GENERIC_WRITE, 0, NULL,
CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
if (INVALID_HANDLE_VALUE == hFile) {
return 0;
}
for (;dwBytesRead>0;)
{
InternetReadFile(hURL, buf, (DWORD)sizeof(buf), &dwBytesRead);
WriteFile(hFile, buf, dwBytesRead, &dwTemp, NULL);
}
// Close down connections.
InternetCloseHandle(hURL);
InternetCloseHandle(hInternetSession);
CloseHandle(hFile);
return 0;
}
