SSIS - using conditional split without losing row-order -


i'm processing flat file in ssis following possible record structure:

action_type   person_id     time_stamp -----------   ---------     ---------------   1 / 2       (9 digits)    (up millis)

logic states have perform operation 1 each person before perform operation 2. also, "actions" can appear in file without limitations: couples of 1's , 2's, 1, 2, etc. each person.

now, flow is:

                                                      __(1)___> perform 1 on person (db) source --> sort operation --> conditional-split --|                                                      |__(2)___> perform 2 on person (db)

everything worked ok, until noticed order of records coming out of conditional-split not preserved - i.e., when "duo of rows" of 1 , 2 same person enters split, might performed together, in parallel - leading race condition or constraint-violation in db (because table built upon assumption 1's performed before 2).

sorting data using timestamp can helpful, split mess order again, sorting i've done here.

any ideas how "sequentiallize" otuput of con-split? can perform flow if fully-sequential mode somehow?

thanks, harel

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
