• ZoltanK Adding ActiveX support to a project that doesn't support it!!!

  Hello, I have a MFC dialog based project that I have been working on and I want to add some activeX controls to it.

• MacDonaldC VC++ 2005 Standard vs. Professional: details needed

  What are the detailed (comprehensive) differences between Visual Studio 2005 Standard and Professional editions (esp. from the C++ perspective) I have read many posts on this topic, but none are definitive or authoritative. For example, http://msdn2.microsoft.com/hs24szh9.aspx lists coarse-grained tools and features, but does not detail what is meant here by a "Streamlined" vs. a "Full" user experience. Also, pages lik ...Show All

Or at reverse situation. In first line intellisense doe ...Show All

• Tomas Floyd Derived Hashtable Problems

  Hi - I have created a class that derives from Hashtable whose items are arraylists, creating a multimap of sorts for which I can iterate through all the items of the same key. I have overwritten the set_Item property method so that adding an item always places it in the arraylist for the given key. I am having trouble with the get_Item method though. If I don't define the get_Item method than I get a compiler error when I try to use it, e ...Show All

• 22DoorsDown 2005 Resource Editor no longer labels language of each dialog

  Back in Studio 6 and Studio2003, when you would edit a dialog resource that had multiple language versions, the window title (Studio 6) or the tab title (Studio 2003) would tell you something like "IDD_DIALOG1 - Italian". This was very helpful if you had several language versions of the same dialog open at the same time. Studio 2005 now labels the tabs as "MyApp.rc - IDD_DIALOG1". This makes it much harder to be sure yo ...Show All

• Tacho Scroll limitation issue

  hi, I have recently taken over the a project for someone, one of the issues we have come across is that you cant view an entire document, in a window with scroll bars if its really big.  I track this problem down to the ranges on the scroll bars.  Once the range of the scroll bar exceeds 32000 pixels, it is set, by my ex-colleague back to 32000.  So when you view a document, depending on the zoom factor you may only see a fractio ...Show All
