c++ - How to correctly access ATL control from ATL Dialog? -

-

i have msvc 2010 solution contains 2 projects:

  • atl dll project, contains dhtml control (named dhtmlcontrol, pretty built wizard). think have placed control second project though.
  • atl exe project, contains main dialog (cmaindialog), created wizard.

i have managed add dhtmlcontrol dialog:

  1. added dhtmlcontrol toolbox
  2. dragged onto main dialog in resource view
  3. removed dhtmlcontrol toolbox (to avoid access denial on build)

however, problem not know how use control!

assuming in scope of maindialog, in:

lresult cmaindialog::oninitdialog(uint umsg, wparam wparam, lparam lparam, bool& bhandled)

what right way invoke dhtmlcontrol's methods? say, navigate url or after button on main dialog pressed.

how can pointer/reference dhtmlcontrol (cdhtmlcontrol? idhtmlcontrol?) being inside of cmaindialog class?

sorry if sounds bit messy struggling atl.

thank you.

include generated _i.h dialog's header (do not include actual control's header - not meant included).

then use this:

ccomptr<idhtmlcontrol> ptr; hresult hr = getdlgcontrol(idc_dhtml_control, iid_idhtmlcontrol, (void**)&ptr);  bstr url = sysallocstring(l"http://example.com/"); // call control's prop method ptr->put_url(url); sysfreestring(url);

What is the difference between data design and data model(ERD) -

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
