I am tring to build a keyboard hook that blocks the
windows keys. It has to be in a seperate dll. The
call to SetWindowsHookEx requires a HINSTANCE to the
dll. How do I get an HINSTANCE to my dll with out
having to use CWinApp. There is way more stuff in the
CWinApp class than I would like to use.

//This works
class CTaskKeyHookDll : public CWinApp
{
public :
	CTaskKeyHookDll(){ }
	~CTaskKeyHookDll(){ }
} MyDll;



//This don't work
class CTaskKeyHookDll
{
public :
	HINSTANCE hInstance;

	CTaskKeyHookDll(){ }
	~CTaskKeyHookDll(){ }
} MyDll;

Anyone know how to do this?

Thank You
Bo Hunter

in your overridden DllMain() save the first parameter(HINSTANCE) to g_hInstance.

Have you thought of a ini file?
If so there is so much code on this site for store and retrieve data.

I guess if you call OpenDocument as many times that many document window and view will be opened.

	// TODO: add reinitialization code here<br />

What do I have to write between lines:
// (SDI documents will reuse this document)
and:
return TRUE;

This may be a little off the wall but you might want to think about the benefits of using Forth. It is a fine training language and will allow you to master the concept of object oriented thinking and open many possibilities for you.

That means a dependent module (DLL or OCX) wasn't installed. Run 'depends' on the OCX and see what might be missing.

Hi can anyone solve the following problems:

1.I have created a dll in vb and want to integrate that in vc++, so how can i go about 'referencing' that we do in vb in the vc++ project .(to add the class created).

2.From the main window iam loading a new dialog.in the child dialog iam selecting an image and subsequently drawing that in the main window by getting the pointer to the main window.the problem is the picture gets erased on subsequent window handling like resizing , being overlapped etc.So how can i pass the image id (its being loaded from the resource) and paint them in the WM_PAINT message handler.

Please help me in this regard.
Thanking you.
