• Visual C++ Error C2440: cannot convert from type to type

  Yesterday I got this error in a new C++/CLI project:   Error 1 error C2440: 'return' : cannot convert from 'ZXNewtonCP::LayoutManager' to 'ZXNewtonCP::LayoutManager' d:\proyectos\rfog\zxnewtoncp\zxnewtoncp\Config.h 17 LayoutManager is a managed class, and is instantiated in class config as a stack type, not a reference or pointer. My intention was to return a reference, but I mistake the typing and got that error. I don’t know if system can return a complete class instead a reference, but the error sounds cryptic and obscure.   Public ref class LayoutManager {…}   Public ref class Config { LayoutManager lay ...Show All

• Visual FoxPro _urlcombobox problem

  I am trying to use this object since it offers much convenience as opposed to shellexecute. This is the problem I run into. When I issue commands in INIT: THIS.AddItem ("www.msn.com",1,1) THIS.AddItem("www.yahoo.com",2,1) THIS.AddItem("www.pdr.net",3,1) The items appear in combobox doubled. This set of urls is repeated twice! Not every url is doubled individualy but the whole set of three urls. This is not all. When I removed the last item, I saw five items in the box: msn.com and yahoo.net were doubled but the last one, pdr.net which is supposed to have been gone appeared as a single item.

• Visual FoxPro cannot open up a form-- BIG TROUBLE

  I have been working on this form for about two months adding new objects and manipulating databases. The last save I did was about 4 days ago. I have a few grids in it on different pages of pageframe and everything worked fine. I never added any columns to any grid at design time. At runtime VFP determines the column layout after a grid is given an alias as a record source. Today, just a few minutes ago I decided to add three columns to a grid which has always been empty at design time. After I did a save, I got an error message at runtime: Error loading file - record number 34: o_Grid2 <or one of its members>. Header Class: ...Show All
