Problems with Direct Input
Author
Hey I'm having a problem in my game where if I resize my window and reset everything, I lose my Joysticks. When I debug it, it goes through the re-initialization process, but when it gets to the Poll() and Aquire(), it fails every time.
I have no idea what the problem is, when I reset, my keyboard control resets right?

Okay now it's even weirder...
It did reset everything and such, but it doesn't reinitialize the Joystick when I switch to a new windowed mode, but when I switch to a fullscreen mode, It works.

This is my initialize function;
This code is my initialize fullscreen
These are my functions for initializing windowed mode
Now the problem is that when I resize the display in fullscreen mode the joysticks reinitialize just fine but when I resize the display to windowed mode it isn't able to aquire the joysticks?

Better fix that and QUICK! The mod isn't going to be happy.

The order in which I re-initialize is as follows:
Now that's not exactly how my code looks it just a summary of my code:
It finds the Joysticks when I first startup the program, but when I switch to a new windowed mode, it no longer is able to find em.
When I switch to a Fullscreen mode it finds them. It doesn't make any sense to me.
DeleteWindow();ResetDevice();CreateDevice();if(FullScreen){InitFullscreen();}else{InitWindowedMode();}LoadFiles();SetupInput();SetupKeyboard();SetupJoysticks();Now that's not exactly how my code looks it just a summary of my code:

Can you tell us what portion of the code fails... Is it failing at EnumDevices, SetCoopeartiveLevel,SetDataFormat
If you start in windowed mode does it work?
Are you creating a new window, because if you are then you would have to pass the new HWND to the joystick.
Try using
DISCL_EXCLUSIVE|DISCL_FOREGROUND

I tried both and it didn't make a difference, but what I did notice is that my keyboard and mouse were not polling and acquiring right away, so I took it out of my init joysticks function, and it worked. So Woo Hoo!
