Taking User confirmation in drools 5.4 -


i have requirement in

  • if validation fails, have ask user whether continue or not.
  • if user says yes, have persist data in db ,
  • if user says no data won't persisted in db.
  • the validations performed in validate.drl.

  • once these validations performed,i have ask user if wants continue or not. process flow follows:

    start -> input.drl -> validate.drl -> takeuserconfirmation.drl -> persistdata.drl

in above flow, have add logic in takeuserconfirmation.drl user should confirm if wants continue or not. depending on answer given i’ll restrict rule in persistdata.drl. execute if user confirms persistence. how can achieve this? can human task i.e. work item handler useful case? how pause drools flow, take user confirmation , start same flow again ?

the question why want in drools. rule file doesn't seem right place user interaction. rather return application code collection of objects validation failed (you can flag them) , if confirmed execute presistdata.drl them.

so in final version have 2 separate flows:

  • input -> validate -> persist (you can have additional flag on object validated checked in persist)
  • persist executed once more after confirmation

also wonder purpose input.drl?

this should rather comment post don't have required 50 rep.

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)...
