Help with ReadFile()

[sonnyk88]

Hello, I wrote this code. All it does is read Readme.txt and displays its content. How could I modify my code so that it could read Readme.txt from a Nth byte position I specify?

For example, the content of the TXT File is: "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

I want my function to read the file from (for example) the F until M and store it in a variable.

I need my function to read only 8 byte of a file from Nth position. Is it possible?? Thanks!

int main(int argc, char* argv[])
{

	HANDLE hFile;

	hFile = CreateFile("H:\\readme.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING,0,0);

	if (hFile == INVALID_HANDLE_VALUE) {
		printf("File was not found\n");
	} else {
	
	DWORD dwFileSize;
	dwFileSize = GetFileSize(hFile, NULL);
    
	if(dwFileSize != 0xFFFFFF) { 
	 
		LPSTR FileContent;
		FileContent = (LPSTR) GlobalAlloc(GPTR, dwFileSize +1);
		if (FileContent != NULL)
		{
		  DWORD dwRead;



          if(ReadFile(hFile,FileContent, dwFileSize, &dwRead,NULL)) {
		     
			  FileContent[dwFileSize] = 0; // NULL TERMINATOR
			  printf(FileContent);
		  }
		  GlobalFree(FileContent);

		}
	}
CloseHandle(hFile);
	}
return 0;
}

Use fseek()
