tab has stopped working

[packetVB]

As I have posted before, Im creating my own GUI class wrappers.
Im having a annoying problem that I just cant figure out.

Somewhere along the process I lost the ability to cycle through the child windows on the form using the tab key.
Every class's createwindow has WS_TABSTOP passed as style. And Im not doing anything with the keypressed events or tab.
So im totally confused as to what has happened.

Ill post the relevant sections of the classes.
Base class for controls message handler

LRESULT CALLBACK vCtrlWindow::baseCtrlMsgHandler(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	LRESULT callreturn;
	vCtrlWindow* pWnd;
	
	//get the class instance from the window
               // using the static member GetObjectFromWindow
	pWnd = GetObjectFromWindow(hwnd);
	//if a valid class object
	if (pWnd)
	{
	//if we getting a left,right,middle button down
	if ( ((uMsg==WM_LBUTTONDOWN) || (uMsg==WM_RBUTTONDOWN) || (uMsg==WM_MBUTTONDOWN)) && (hwnd==pWnd->m_hwnd))
	{
		int xpos=0;
		int ypos=0;
		long flags=0;
		int shift=0;
		int button=0;
		//set flags to wPara. Need to check it to tell if shift or ctrl key
		//was being pressed when control was click
		flags=wParam;
		//xpos=left-right position of mouse
		xpos=LOWORD(lParam);
		//ypos=up-down position of mouse
		ypos=HIWORD(lParam);
			
//I know, I know. This should be improved.
		//shift key
		if ((flags | MK_SHIFT)==flags)
		{
			shift=shift+1;
		}
		//ctrl key
		if ((flags | MK_CONTROL)==flags)
		{
			shift=shift+2;
		}
		//what button was pressed. 
		if (uMsg==WM_LBUTTONDOWN)
		{
			pWnd->lastMessage=uMsg;
			button=1;
		}
		if (uMsg==WM_RBUTTONDOWN)
		{
			pWnd->lastMessage=uMsg;
			button=2;
		}
		if (uMsg==WM_MBUTTONDOWN)
		{
			pWnd->lastMessage=uMsg;
			button=4;
		}
		//you must call the windows procedure before making
		//the function call or the message gets lost. So I assume.
		//callreturn=CallWindowProc((WNDPROC)pWnd->originalProc,hwnd, uMsg, wParam, lParam);
		
		callreturn=pWnd->CtrlMsgHandler(hwnd, uMsg, wParam, lParam);
		//call this objects OnMouseDown Function
		pWnd->OnMouseDown(button,shift,xpos,ypos);
		return callreturn;
		
	}
			
	return pWnd->CtrlMsgHandler(hwnd, uMsg, wParam, lParam);
	
	}
	//else we couldnt get a valid pointer to a class object
	else
	{
		//so call the original windows procedure
		return CallWindowProc((WNDPROC)pWnd->originalProc,hwnd, uMsg, wParam, lParam);
	}
}

textbox control is derived from vctrlwindow

LRESULT CALLBACK vTextBox::CtrlMsgHandler(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	LRESULT callreturn;
	
	long hwParam=0;
	long lwParam=0;
	long tttt;					//debug only
	hwParam=HIWORD(wParam);
	lwParam=LOWORD(wParam);
	
	//*******************	USED FOR DEBUG ONLY   ****************
	if ((uMsg==WM_CHAR) && (wParam==9))
	{
		tttt=0;
	}
	//*************************************************************

	//if the current message is left button up and the last message was
	//SetFocus or left button down then treat this as a click.
	if ((uMsg==WM_LBUTTONUP) && ((lastMessage==WM_SETFOCUS) || (lastMessage==WM_LBUTTONDOWN)))
	{
				//call the original message first
				callreturn=CallWindowProc((WNDPROC)originalProc,hwnd, uMsg, wParam, lParam);
				//set the lastmessage to this message
				lastMessage=uMsg;
				//call this instance Click member function
				OnClick();
				//return what the original procedure 
				return callreturn;
	}

	//if the messages hwnd is this control parent
	if (hwnd==p_hwnd)
	{
		//and if the message is a command
		if (uMsg==WM_COMMAND)
		{
			//if the command is update
			if (hwParam==EN_UPDATE)
			{
				//call the original message first
				callreturn=CallWindowProc((WNDPROC)originalProc,hwnd, uMsg, wParam, lParam);
				//set the lastmessage to this message
				lastMessage=uMsg;
				//call the OnChange member function
				OnChange();
				//return what the original procedure return with
				return callreturn;
			}
		}
	}	

	//call the original proc
	return CallWindowProc((WNDPROC)originalProc,hwnd, uMsg, wParam, lParam);
}

base class for main windows message handler

LRESULT CALLBACK vBaseWindow::baseWinMsgHandler(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	vBaseWindow* pWnd;
	
	if (uMsg==WM_NCCREATE)
	{
		// use the pointer to the window from lpCreateParams which was set in CreateWindow
		SetWindowLong(hwnd, GWL_USERDATA, (long)((LPCREATESTRUCT(lParam))->lpCreateParams));
	}
	

	pWnd = GetObjectFromWindow(hwnd);
	if ((uMsg==WM_CLOSE) && (pWnd))
	{
		pWnd->OnClose(hwnd);
		return false;
	}
	if ((uMsg==WM_DESTROY) && (pWnd))
	{
		pWnd->OnDestroy(hwnd);
		return false;
	}

	if (pWnd)
	{
		pWnd->WinMsgHandler(hwnd, uMsg, wParam, lParam);
		return DefWindowProc(hwnd, uMsg, wParam, lParam);
	}
	else
	{
		return DefWindowProc(hwnd, uMsg, wParam, lParam);
	}
	//return false;
}

main window is derived from vbasewindow

BOOL CALLBACK vForm::WinMsgHandler(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	long hwParam=0;
	long lwParam=0;
	int tttt;
	hwParam=HIWORD(wParam);
	lwParam=LOWORD(wParam);
	if (uMsg==258)
	{
		tttt=0;
	}
	if ((m_hwnd!=0) && (uMsg==WM_COMMAND))
	{
		HWND cwnd;
		cwnd=HWND(lParam);
		long resIdent;
		resIdent=GetWindowLong(HWND(lParam),GWL_ID);
		
		if (resIdent==lwParam)
		{
			tcontrol=GetObjectFromCtrl(HWND(lParam));
			if ((tcontrol))
			{
//call the child control message handler
				tcontrol->CtrlMsgHandler(hwnd,uMsg,wParam,lParam);
				return false;
			}
		}
	}



	return false;
}

Everything else works fine. Any help would be great.
Also would it be better to attach the full src?

Thanks
