• Dya Clean Build Fails -- Close, Restart, Build Succeeds

  We are experiencing problems getting our nightly clean builds to work. We have a C++/CLI project that includes multiple references to COM objects. All those COM objects are build as part of the larger solution. Dependencies are set properly. When a build is performed in an environment where there has not been a build before, that project fails to build. After the failure, if you look at the references in the C++/CLI project, one of the COM libra ...Show All

• marbanno Justification for forcing 'virtual' for overridden virtual functions

  Since C++ does not force a programmer to specify the 'virtual' keyword when overriding a virtual function in a base class, what was the justification for forcing not only 'virtual' but also an after the parameter list 'override' when overriding virtual functions of a base ref class or interface class. For normal C++ programmers this bifurcation from C++ seems both a PITA and absolutely unnecessary. There must have been some practical reason for ...Show All

  Hi. I'm having some troubles when performing this conversion. In my C# code I read a image to memory, a TIFF, then I convert this to a ByteArray.

• Walt-the-IT-Guy Copy contents of int to float

  I'm trying to copy the contents of an int variable into a float variable... In native code I could just do a memcpy, but I'm having trouble figuring out how to do it with the new .NET code in Visual Studio 2005. So for example, I have an integer value of: 1073741824 or 0x40000000 in hex, and I want it to copy it into a float variable thus having a value of 2.0. Basically I want to preserve the bits, but have the variable be a different type. I d ...Show All
