Ok, so i can get the registry to give me a string, but i have a problem with getting a dword value. Here is an example of what i am trying to do:
However, even though i have the registry value "SettingA" set as 0x10 (16 dec) reg_value always turns out 0. Anyone know whats wrong?Code:DWORD reg_value, dw; if (RegQueryValueEx (Key, "SettingA", NULL, NULL, (LPBYTE) reg_value, &dw) != ERROR_SUCCESS) Alert("You have a problem!");
HA! I WIN!
Use the fourth parameter to see what type it actually is being stored as. Granted, "float" is not an option. If you put 0x10 into a float using a memcpy-type operation (which you did here), you will get a value of 2.2420775429197073e-44 back, which will probably print as 0 unless you print it with %e or %g.
reg_value is declared as a DWORD, not a float. I want to get 16dec into the variable reg_value which should work. Actually in my program I did use the fourth parameter and I am getting the correct type, the variable is simply not loading right. Can anyone provide a short example of how this is supposed to be done?
HA! I WIN!
Wow. Don't ask me where I got float from, 'cause it's just not there. Anyway, the fifth parameter needs to be a pointer to the data.
I think im still missing something... is it right to cast reg_value to LPBYTE to pass it in, or does reg_value need to be a pointer? I just can't understand why this is goin on...
HA! I WIN!
i got it... i didnt realize that i needed to pass it as "(LPBYTE) ®_value" and not "(LPBYTE) reg_value". Thanks!
HA! I WIN!
Not that confusing -- you got it right the second time:
Code:if (RegQueryValueEx (Key, "SettingA", NULL, NULL, (LPBYTE) ®_value, &dw) != ERROR_SUCCESS)
