Recently I’ve been asked how you can make method find of std::string case insensitive. An obvious solution is to transform the strings to lower case, for instance, and perform the search in lower case. The solution has some inconvenients and a clean and nice solution is defining custom traits that ignore the case. The solution I’m … Read more
If you want to find an item in a tree control (CTreeCtrl from MFC) by its name you need a recursive function. Below is a function that does that. How does it work: you pass the text of the item to search, the tree reference and an item in the tree. The function will search … Read more

I have decided to make a comparison for file IO operations on Win32, CRT, STL and MFC. For all four libraries/APIs I have done the profiling in the following way: open the file allocate the buffer used for reading start the timer read/write from/to the file stop the timer close the file release the memory … Read more
Every once in a while, IÂ run into this site teaching techniques for writing unmaintainable code. Of course, the hole purpose is to teach exactly the contrary (or at least that’s what I hope). Some of my favorite techniques are: use of single letter variable names, which of course makes searching almost impossible, and even less … Read more
