RegOpenKeyEx Notes
Keywords: RegOpenKeyEx Notes
The following is a little object lesson in registry access modes. I was stuck for hours on this.
You have to apply the mode at the layer where the restriction is set, not simply to the final destination.
In the following example, the Runonce key is apparantly write-only!
;put the value in place, then try to read it
regsetvalue(@REGCURRENT,"\Software\Microsoft\Windows\CurrentVersion\Runonce[COLORS]", "xyzzy")
;method 1 (fails)
;x = regquerystr(@REGCURRENT,"\Software\Microsoft\Windows\CurrentVersion\Runonce[COLORS]")
;method 2 (fails)
;w = regopenkeyEx(@REGCURRENT,"\Software\Microsoft\Windows\CurrentVersion\Runonce",1|8,"","")
;x = regqueryvalue(w,"[COLORS]")
;RegCloseKey(w)
;method 3 (works)
wa = regopenkey(@REGCURRENT,"Software\Microsoft\Windows\CurrentVersion")
wb = regopenkeyEx(wa,"Runonce", 1, "","")
x = regqueryvalue(wb,"[COLORS]")
RegCloseKey(wb)
RegCloseKey(wa)
message("x=",x)
exit
