This piece of code creates and reads OK a key at "HKEY_LOCAL_MACHINE" and can be changed for a key at "HKEY_CURRENT_USER"
$sta= RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor", "wav", "REG_SZ", "5555") MsgBox(4096,"wrote", $sta &@cr& @error) $zz= RegRead ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor", "wav") MsgBox(4096,"readed","="&$zz &@cr& @error) Exit With HKEY_CURRENT_USER, in RegEdit we can see the created key, and we can create the key by hand/RegEdit and everything Works OK.
At HKEY_LOCAL_MACHINE we can´t see the created key above thru RegEdit, but it Works (even not seeing, I can read). But if I create "by hand"/RegEdit the key, it can´t read it with $zz= RegRead ("HKEY_LOCAL_MACHINE.... above.
I´m the PC´s WIN.7 administrator. Even so I ran RegEdit as administrator and also the compiled AU3 and also plain. No changes.
edit: even if Try "HKEY_LOCAL_MACHINE\SOFTWARE\AAA", "wav", the same holds true.
$sta= RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\AAA", "wav", "REG_SZ", "4444") MsgBox(4096,"wrote", $sta &@cr& @error) $zz= RegRead ("HKEY_LOCAL_MACHINE\SOFTWARE\AAA", "wav") MsgBox(4096,"readed","="&$zz &@cr& @error) Exit Seems that it creates this key at another place.... I can read the above value ("4444"), even after a boot, even the key not showing in regedit. And if I create it by hand key AAA/wav with a distinct value (666), t, it continues Reading the old value = 444.
good morning everybody.
today i liked to share an small example with you
which it an function to read the registry values as an array
the result array is 2d array witch
$a_array[n] = value name
$a_array[n] = value Data
$a_array = values count
here's the function
#include <Array.au3> #include <WinAPIReg.au3> #include <APIRegConstants.au3> Local $a_array = _RegReadToArray("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run") If @error Then MsgBox(16, "error", @error) Exit EndIf _ArrayDisplay($a_array) Func _RegReadToArray($s_RegKey) Local $a_KeySplitInfo = StringSplit($s_RegKey, "\\", 2) If UBound($a_KeySplitInfo) <= 1 Then $a_KeySplitInfo = StringSplit($s_RegKey, "\", 2) If UBound($a_KeySplitInfo) <= 1 Then Return (1, 1, 0) EndIf Local $H_KeyInfo = "", $s_RegKeyInfo = "" Switch $a_KeySplitInfo Case "hklm", "HKEY_LOCAL_MACHINE", "hklm64", "HKEY_LOCAL_MACHINE64" $H_KeyInfo = $HKEY_LOCAL_MACHINE Case "hkCu", "HKEY_CURRENT_USER", "hkCU64", "HKEY_CURRENT_USER64" $H_KeyInfo = $HKEY_CURRENT_USER Case "hkCr", "HKEY_CLASSES_ROOT", "HKCR64", "HKEY_CLASSES_ROOT64" $H_KeyInfo = $HKEY_CLASSES_ROOT Case "HKU", "HKEY_USERS", "HKU64", "HKEY_USERS64" $H_KeyInfo = $HKEY_USERS Case Else Return SetError(2, 2, 0) EndSwitch _ArrayDelete($a_KeySplitInfo, 0) $s_RegKeyInfo = _ArrayToString($a_KeySplitInfo, "\") Local $H_KeyInfoOpen = _WinAPI_RegOpenKey($H_KeyInfo, $s_RegKeyInfo, $KEY_READ) Local $A_KeyInfo = _WinAPI_RegQueryInfoKey($H_KeyInfoOpen) If @error Then Return SetError(1, 1, 0) _WinAPI_RegCloseKey($H_KeyInfoOpen) Local $A_RegVal[$A_KeyInfo + 1] Local $iV = 1, $s_RegRead = "" While 1 $s_RegVal = RegEnumVal($s_RegKey, $iV) If @error <> 0 Then ExitLoop $s_RegRead = RegRead($s_RegKey, $s_RegVal) If Not (@error) Then $A_RegVal[$iV] = $s_RegVal $A_RegVal[$iV] = $s_RegRead EndIf $iV += 1 WEnd $A_RegVal = UBound($A_RegVal) - 1 If $A_RegVal >= 1 Then Return $A_RegVal Else Return SetError(3, 3, 0) EndIf EndFunc ;==>_RegReadToArray
i hope you benefit from it
with my greetings
I wondered why negative integers I wrote into registry (e.g. negative x-coordinates of a gui if using two monitors and the right one is the main one) wouldn't return right when reading. Now I know: it is saved as an unsigned integer (without algebraic sign). So here is a snippet that is changing unsigned to signed integer:
Global Const $g_sRegKey = "HKEY_CURRENT_USER\Software\" & @ScriptName ; path to registry RegWrite($g_sRegKey, "Value", "REG_DWORD", -2147483647) ; write some negative integer into registry; -2147483647 highest possible negative integer , 2147483648 highest possible positive integer if talking of 32bit Local $sValue = RegRead($g_sRegKey, "Value") ; read out registry ConsoleWrite("Value: " & $sValue & @CRLF) ; show real value in console Local $sResult = _SignedInteger($sValue) ; change to signed value ConsoleWrite("Result: " & $sResult & @CRLF) ; and show it in console Func _SignedInteger($iUnsignedInteger) Local $iSignedInteger If $iUnsignedInteger > (2^31) Then ; then it means a negative integer $iSignedInteger = $iUnsignedInteger - (2^32) Else $iSignedInteger = $iUnsignedInteger EndIf Return $iSignedInteger EndFunc It took me some time to find out the problem and so I hope I can help somebody with this.
I'm writing a little applet that basically tells you when Windows was installed. There is a REG_DWORD in Windows that gives you this. It's basically a value that is the # of seconds from 1970.
The location is: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate"
So if I run this in AutoIT, I should get the value displayed within the msgbox:
MsgBox($MB_SYSTEMMODAL, "InstallDate Test", RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "InstallDate"))
However, what happens is it always returns a value of "0" I tried this on several machines (Windows 8, Windows 8.1 and Windows 10).
Am I missing something? If I manually view this REG_DWORD with RegEdit, it shows me the HEX value, or I can view the Decimal value. I don't care which value AutoIT reads, as I can always convert back and forth, but I just don't see why it can't read a value from this REG_DWORD. As a test, I've read other REG_DWORD values, and with most it doesn't return any value, not even a 0.
Please, even if you guys have some other (perhaps better) way to read the Windows install date, I would still like to find a resolution to this problem, because I want to understand why I am having so much difficulty with reading REG_DWORD values from the Windows Registry with AutoIT.
Thanks for any help!
