c# - A Workflow Foundation 4 argument of a nested type -


one of arguments workflow (xaml) nested type declared in static class. unfortunately, "browse .net type" dialog box not show me type irrespective of search for

full.namespace.containingstaticlass.typeineed

or

full.namespace.containingstaticlass+typeineed

since dialog didn't work, tried editing xaml couldn't figure out how define

type="inargument(xmlnamespacetomyassembly:???)"

help!?

edit: seems workflow designer not work nested types @ all, because expression cast object nested type gave me error.

enter image description here

at point, workarounds welcome!

added simple sample shows problem.

  1. there no way add parameter (in designer) of type nestedtype.essentialstruct
  2. even if add expression cast object nestedtype.essentialstruct in properties window against inargument, designer complain.

posting relevant sections also:

the nested type needs used in codeactivity

public static class nestedtypes {     public struct essentialstruct     {     } }

a simple activity uses nested type inargument , result

public sealed class testactivity : codeactivity<nestedtypes.essentialstruct> {     public inargument<nestedtypes.essentialstruct> handle     {         get;         set;     }      protected override nestedtypes.essentialstruct execute(codeactivitycontext context)     {         return context.getvalue(this.handle);     } }

i can't post xaml produces error because designer doesn't save it, errors out before saving it.

you need use import on workflow. it's tab in designer. it's next variables , arguments.

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)...
