Thread: Why does my prog just stop?

Why does this program just stop right after checkpoint 3 comes up? I know it has somthing to do with the InternetReadFile(), but this script has worked before.

MY_PASSWORD is just that. But my real one goes there in my program. And IE executes these address' just fine.

Thanks for any help, August.

Code:

 #include <tchar.h>
#include <gwc.h> // Holds cp(int);
void tGetInternetFile(char buffer[], LPCTSTR szURL, size_t cbMaxSize, size_t* lpcbActualSize)
{
HINTERNET hNet		 = NULL;
HINTERNET hUrlFile	 = NULL;
DWORD	 cbBytesRead = 0;
SIZE_T	cbBytesTotal = 0;
BOOL	 bResult	 = FALSE;
const DWORD cbReadSize = 0x4000;
 
cp(0);
 
	if (!(hNet = InternetOpen(TEXT("Downloader"), PRE_CONFIG_INTERNET_ACCESS, NULL, NULL, 0)))
	{
		cp(-1);
goto cleanup;
	}
	else
		cp(1);
 
if (!(hUrlFile = InternetOpenUrl(hNet, szURL, NULL, 0, INTERNET_FLAG_RESYNCHRONIZE, 0)))
	{
		cp(-2);
goto cleanup;
	}
	else
		cp(2);
 
do
{
if (!(buffer = (char*) ReallocOrFree(buffer, cbBytesTotal + cbReadSize)))
		{
			cp(-3);
goto cleanup;
		}
		else
			cp(3);
 
if (!InternetReadFile(hUrlFile, buffer + cbBytesTotal, cbReadSize, &cbBytesRead))
		{
			cp(-4);
goto cleanup;
		}
		else
			cp(4);
 
cbBytesTotal += cbBytesRead;
 
/* Max size check and size_t overflow check */
if (cbBytesTotal > cbMaxSize || ((((size_t) -1) - cbReadSize) - 1) < cbBytesTotal)
		{
			cp(-5);
goto cleanup;
		}
		else
			cp(5);
 
} while (cbBytesRead > 0);
 
if (!(buffer = (char*) ReallocOrFree(buffer, cbBytesTotal + 1)))
	{
		cp(-6);
goto cleanup;
	}
	else
		cp(6);
 
buffer[cbBytesTotal] = '\0';
bResult = TRUE;
 
cleanup:
if (hUrlFile) InternetCloseHandle(hUrlFile);
if (hNet)	 InternetCloseHandle(hNet);
if (!bResult) free(buffer);
if (lpcbActualSize) *lpcbActualSize = (bResult ? cbBytesTotal : 0);
 
return;
}
