Hooks

I am currently wolking on a on a C project to convert QWERTY keystrokes to DVORAK keystrokes for the system. I googled and found I have to use a global keybeard hook, but I am not exactly sure how to get it working. Allot of the resourses I found were not any good. what exactly do I have to do to get the hook set up.

And I have never written or used a DLL in C before. Are there any resourses that you have in mind that may teach me that? (at least the basics so I can write the needed DLL for this project) I googled and found several different explinations as to wirting them, which all said to do different things, and none explained loading them in C(but rather in other languages). So I know neither how to write them or lead them.

I hope you under stand what I am asking. Not to have you write even parts of the program for me, but explain how to use (keyboard) hooks, and use/write DLLs.

You already asked this question here, and I told you in that thread why global hooks wouldn't work for you.

Yes, but I am still looking to do it as a learning experience. I have a windows PC here with admin privliges that I can test it on.

Hooks are set with the SetWindowsHook() or SetWindowsHookEx() function. Read the MSDN documentation for information on how to use the function.

When you call SetWindowsHook(), your hook gets added to a global chain of hooks. Since this chain must be persistant (even when your application is not running) a hook procedure must be in a DLL. A tutorial on how to make DLL files is outside the scope of a message board post, but you can get plenty of information from google on that.

I wrote up a little example on how to create and set a keyboard hook on this board once. If you do a board search, you can probably find it.

Thanks. I saw the SetWindowsHook function in what I did read on them. And somewhat how to use them, but not a great deal I will defenatly seargh for your example. I hope it isn't burried too far. I could probably ask about the C DLL in the general C board. I will later if I cant find anything more in my searches.
