[Closed] SDK ParamBlock2 DlgProc

I’ve been doing my DlgProcs for my ParamBlock2 a way I found in a sample. Although, after looking at different samples, not many of them seem to be using this way. So I was wondering how other people are doing and if there is a better way. As I’m starting to get small issues with it. Thanks

static SpaceTool *theSpaceTool;
  
  class DisplayDlgProc : public ParamMap2UserDlgProc{
  	public:			
  	INT_PTR DlgProc(TimeValue t, IParamMap2 *map, HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam){
  		static DRAWITEMSTRUCT* pdis;
  		theSpaceTool = (SpaceTool*)map->GetParamBlock()->GetOwner();
  		switch (msg){
  			case WM_DRAWITEM:
  				pdis = (DRAWITEMSTRUCT*) lParam;
  				theSpaceTool->DrawButtons(pdis, hInstance);
  				break;
  			case WM_CTLCOLORBTN:
  				HBRUSH hBrushBtn;
  				hBrushBtn = (HBRUSH) GetStockObject(NULL_BRUSH);
  				SetBkMode((HDC) wParam, TRANSPARENT);
  				return ((LRESULT) hBrushBtn);
  			case WM_NOTIFY:
  				switch(LOWORD(wParam)){
  				
  				}
  				break;
  			case WM_INITDIALOG:{
  				ExecuteMAXScriptScript(_T("print \"Display\""), 0, 0);
  				theSpaceTool->pblock2 = theSpaceTool->GetParamBlockByID(0);
  				break;
  			}
  			case WM_COMMAND:
  				switch( LOWORD(wParam)){
  					}
  				break;
  			default:
  				return FALSE;
  		}
  		return TRUE;
  	}
  	void DeleteThis(){};
  };
