• Windows Forms Suprising performance increase

  Hello, I recently stumbled across a huge performance difference involving writing out a large hash table to a file.  The hashtable is holding a very simple object called Token, that holds a string value called token and a couple counters.  ToString() is overriden for the object to return: tokenstring [space] counter1 [space] counter2 If I iterate through the va ...Show All

  I had only understand one design pattern, singleton. :( I had read a couple of other design pattern but i didn't found the one suitable regarding my question.

• Visual Studio Team System Create Private Accessor and generic collections?

  Hi, the generated wrapper class to access private members doesn't contain any accessors for fields with a generic type, e.g. private Dictionary< string , CacheEntry> m_cache;   Does anybody know a workaround for this problem Thanks, Andy Thanks for the answer, Michael. I really hope that some support will be included in the final release, since things like private generic Dictionaries used as internal data structures are likely to become common, we already use them extensively, for the usual reasons (type safety, performance). It would be a shame if it would not be possible to access ...Show All

  I noticed this problem just this morning after spending many hundred hours debugging my app for the past few months when everything worked just fine. This is the setup which is hardly unusual. There is a function in a prg file and a Click method that calls it. There are a couple of print statements like: "coimng out of the function: "+numeric_id and such in the function(s) and one in the Click method. All output is character strings. The button is clicked many times during the debug. I get only one line of output out of the function but the rest of it is overlapping this first line no matter where it is coming from.
