When I click on a file named x.abc or if I type x.abc from the command prompt, the ClickOnce application starts, and I can retrieve the file through the dedicated API. I can also launch the application programmatically with the following code: System.Diagnostics.Process.Start ("x.abc"); Manual start of x.abc by double-clicking it from the Explorer works. Manual start of x.abc from the command prompt works.

This is simple with IPv4 where the 32 bit address can fit into an integer column. However, an IPv6 address is 128 bits. The MySQL documentation only shows numeric types up to 64 bits ("bigint"). Should I stick with char/varchar for IPv6? (Ideally I'd like to use the same column for IPv4 and IPv6, so I'd prefer not to do this). Is there anything better than using two bigint columns? I would prefer not to have to break the value into upper and lower /64 whenever

I have yet to find a method which will preserve the 16 bit depth per channel when dealing with the TIFF format. I am hoping that some helpful soul will have a solution. Here is a list of what I have tried so far without success and the results: import numpy as np import PIL.Image as Image import libtiff import cv2 im = Image.open('a.tif') # IOError: cannot identify image file tif = libtiff.TIFF.open('a.tif') im = tif.read_image() # im only contains

For example (using the 8 bits integers for simplicity) I want to achieve the following: let unsigned: UInt8 = toUInt8(-1) // unsigned is 255 or 0xff let signed: Int8 = toInt8(0xff) // signed is -1 At first I came out with the following solution: let unsigned = unsafeBitCast(Int8(-1), UInt8.self) let signed = unsafeBitCast(UInt8(0xff), Int8.self) But Apple in the "unsafeBitCast()" documentation states the following: .. Caution:: Breaks the guarantees of

Because a SHA-1 value is always 160 bit long, the VARCHAR would just waste an additional byte for the length of the fixed-length field . And I also wouldn’t store the value the SHA1 is returning. Because it uses just 4 bit per character and thus would need 160/4 = 40 characters.

See the declaration of struct iphdr in linux kernel for an example of such code. I fail to understand why bit endianness is an issue at all. As far as I understand, bitfields are purely compiler constructs, used to facilitate bit level manipulations. For instance, consider the following bitfield: struct ParsedInt { unsigned int f1:1; unsigned int f2:3; unsigned int f3:4; }; uint8_t i; struct ParsedInt *d = &i; Here, writing d->f2 is simply a

This program needs to be able to access the C:\Windows\system32\ folder on a computer, regardless of whether the program is running on a 64-bit or 32-bit system. To do this, I was using Wow64DisableWow64FsRedirection to disable the redirection that Windows typically does to 32-bit processes, sending them to C:\Windows\syswow64 . Unfortunately, this breaks compatibility --
