Hello! I'd like to know if the win32 api has a function to pop a message box with text and an input field, a bit like javascript's windows.prompt() . I'm looking for a simple way of getting input from the user. cin does not seem to work with a console created with AllocConsole(). Thank you!

Unfortunately, there is no API function for this as part of Windows.

If you'd like to read input from a console that you've opened with AllocConsole(), have a look at the ReadConsole function.

Aside from that, the easiest way to do it is probably to build a simple dialog resource with the input controls you want, and write some wrapper code to display that on demand.

Thanks a lot!

I think I'll try the ReadConsole way, msdn defines it like this :
BOOL ReadConsole(
HANDLE hConsoleInput,
LPVOID lpBuffer,
DWORD nNumberOfCharsToRead,
LPDWORD lpNumberOfCharsRead,
LPVOID lpReserved
);


May I ask you how I can get the handle "hConsoleInput" of the console I created with AllocConsole?
EDIT : Would it be GetStdHandle(STD_INPUT_HANDLE) ?

Just a small post to tell you I found an easier way of doing it :

AllocConsole();
freopen( "CONOUT$", "w", stdout );
freopen( "CONIN$" , "r", stdin );
std::ios::sync_with_stdio();


That's it! Thanks again

If you still want a custom message box though, you could use SetWindowsHookEx.
