api - RESTful way to preallocate an ID -


for reasons application needs have api flows like:

  1. client calls server id new resource.
  2. then user spends while filling out forms resource.
  3. then user clicks save (or not...), , when client saves writing /myresource/{id}

what restful way design this?

how should first call like? on server side, it's matter of generating id , returning it. has side effects (increments sequence , "reserves space"), doesn't explicitly create resource.

if understand correctly, 3rd call should put because creates known uri.

one way is:

  • client posts empty body /myresource/
  • server answers status code 302 (found) location response header set /myresource/newresourceid (to indicate id / uri should used create resource)
  • client puts new resource /myresource/newresourceid once user done filling form.

seems restful enough. ;)

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
