I want to download file from a given URL. I am using URLDownloadToFile() function for this purpose, but I am not getting the actual file. When I try to run the file, it throws an error.
As an example, If I download MSVS 2010 service pack 1 from Microsoft's website, the file size will be 795KB. But if I download using URLDownloadToFile() function passing the url and file name, downloaded file size will be 99 KB.
Is there any method to download an exe from a URL in C++.
You must pass the complete URL to the file. When browsing MS for downloads, they are often provided by a confirmation page that will start the download. If you pass that URL, wou will download the web page content. On such pages you will usually find a link to the real file if the download does not start after some time.
I've been trying to make a simple tracking game but I'm having trouble just setting up the basic game states. I'm hoping to use a finite state machine(FSM) to switch between screens but every article iv read about them is different and sometimes they leave out details, I couldn't understand it properly.
For example if I've two screens , Menu and Game screen. And in game I've to implement states for a simple tracking game. What would be a FSM look like to switch between them.??
but every article iv read about them is different and sometimes they leave out details, I couldn't understand it properly.
They are different because FSM are widely used, for different purposes.
There are not may details to understand. A finite state machine is a rather simple stuff. You should understand your scenarion, though.
By wild guess, you could do something like (or go with a more OO approach)
// other useful data
void update_fsm(FSMData & fsmd)
void handle_menu(FSMData & fsmd)
if ( userSelection() == PLAY_GAME)
// cleanup here
fsmd.state = STATE_GAME;
void handle_game(FSMData & fsmd)
if (userInput() == QUIT_GAME)
// cleanup here
fsmd.state = STATE_MENU;
CPallini has given you a basic example for a FSM - you will understand that we're not here to provide ready solutions. You have formulated your game states - what stops you from extending that sample with that, or, at least trying?
