What would be the best (fastest, nicest looking code) to do this? I've done this in c++ and did something like this: uint8_t *buffer; uint32_t value = buffer[0] | buffer[1] << 8 | buffer[2] << 16 | buffer[3] << 24; But in Java this causes a problem if for example buffer[1] contains a value which has it sign bit set as the result of a left-shift is an int (?). Instead of OR:ing in only 0xA5 at the specific

The dll is loaded (first interop call happens) when user opens a file via a dialog within the application. When I deploy the application via clickonce with target platform "Any", users on 64 bit windows get BadImageFormatException when trying to open files from the application (at the moment the unmanaged dll is loaded). I understand this is due to incompabible bitness of the 64 bit process and the 32 bit unmanaged dll. I have redeployed the application using x86 as target platform. As I

Previously we provide always 3 different releases, one for 32-bit Windows, one for 32-bit Linux and another for 64-bit Linux, with an installer which has JRE included. The 64-bit version was not used by anyone until couple of weeks ago, and an OutOfMemoryException was reported because the application consumes about 40-50% more memory than the 32-bit version. My question

The following code works but there is an extra BlockCopy I would like to get rid of. Marshal.Copy does not support ushort. What can I do? (FYI: the rawbits is filled in by a video framegrabber card into unmanaged memory) public const int width = 2056; public const int height = 2048; public const int depth = 2; public System.IntPtr rawbits; public ushort[] bits() { ushort[] output = new ushort[width * height]

So is there any 32-bit binary version of the MinGW compiler that can both compile for 32-bit Windows and also for 64-bit Windows? I don't want a 64-bit version that can generate 32-bit code, since I want the compiler to also run on 32-bit Windows, and I'm only looking for precompiled binaries here, not source files, since I've spent countless hours compiling GCC and failing, and I've given up for a while. :( 回答1: AFAIK mingw targets either 32 bit

I want to add two binary numbers by hand: 1.001 2 * 2 2 1.010,0000,0000,0000,0000,0011 2 * 2 1 I can add them no problem, I get the following result after de-normalizing the first number, adding the two, and re-normalizing them. 1.1100,0000,0000,0000,0000,0011 2 * 2 2 The issue is, that number will not fit into single-precision IEEE 754 format without truncating or rounding one bit. My assignment asks that we put
