I have run into a couple of similar quirks regarding uint usage in both C++ and C#, and now I'm wondering on the reasoning (which may be completely different for each example). For both of these examples, note that I am compiling with the warning levels set to maximum. (1) gcc complains about comparing an int to a uint in the following...
Here is the situation - I developed my application in VC++ 2008, using Windows Forms/Managed Code. It runs fine. However, I need it to run on a Windows 2000 machine, and, if possible, not need any additional DLLs/installs aside from the 2.0 framework. I looked around, and most of the answers I got were about not needing MSVCR90.dll on ...

I have a Java application that uses a C++ DLL via JNI. A few of the DLL's methods take string arguments, and some of them return objects that contain strings as well. Currently the DLL does not support Unicode, so the string handling is rather easy: Java calls String.getBytes() and passes the resulting array to the DLL, which simply ...
