c++ - How to read the temperature from sensors on the motherboard? -


trying temperature of processor.

have tried using wql (wmi class msacpi_thermalzonetemperature), apparently not implemented platforms yet. on of machines returns every existing error message via hresult return value. temperature not returned.

the idea read temperature directly via bus port. have found library, gives functionality of outp , inp functions, , managed start initiate connection (ntport), however, question becomes port connect in order read data. microcontroller it8728f. speedfan (the application able read temperature) in logs says reads data port 0x290. however, when connecting it, data comes not temperature (it returns 29).

so next thing tried read whatever port, trying determine if data came through looked temperature. however, every port data came through either low or high real temperature.

int cpu_temp; outp(index, bank_set); outp(data, inp(data)|0x01); for(cpu_temp=0x0;cpu_temp<0x999;cpu_temp++) {   outp(index, cpu_temp);   printf("cpu temp: %ic\n", inp(data)); }

maybe processor 29 degrees celsius , stable. seems legit processor.

also: 0x00000029 or dec 29? makes big difference

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)...
