I have ported our project from Delphi 7 to Delphi 2010. After adding some type casts now my project is running well and all the features work correctly except main functionality of the program which is bound to COM ports and the MSCOMM ActiveX component. It can read and write from a COM port but it seems something is wrong with that bec...
I have a bit counting method that I am trying to make as fast as possible. I want to try the algorithm below from Bit Twiddling Hacks, but I don't know C. What is 'type T' and what is the python equivalent of (T)~(T)0/3? A generalization of the best bit counting method to integers of bit-widths upto 128 (parameterized by type T...

Is there an easy way to make some "sleeping program" functionality by just calling function, such as it has been made in Java with Thread.sleep()? Sleep method causes, in brief, app to wait indicated time (no. of milisec.) and after that time returns to next line of code (so it "blocks" - it isn't not proper word, though - the current t...
In .NET when I had a "value" that could exist as multiple types I could easily use a TypeConverter for switching between those types (currency types, xml data vs object representation, ect). In Java, I am not sure what the preferred way to handle this situation is. Is there a TypeConverter equivalent in Java? ...

Hi, We'd like to serialize data in a specific binary format. We use Data.ByteStrings internally. So, the question is: How to convert the different data types we use to a ByteString. For String we have no problem, we can use encodeLazyByteString UTF8 "string". But we'd also like to convert Integers to ByteStrings (big-endian). Does any...
I'm familiar with WideCharToMultiByte and MultiByteToWideChar conversions and could use these to do something like: UTF8 -> UTF16 -> 1252 I know that iconv will do what I need, but does anybody know of any MS libs that will allow this in a single call? I should probably just pull in the iconv library, but am feeling lazy. Thanks ...
