Regopenkeyex Error 87

You have to use RegDeleteKeyEx with same keys. Any idea what I am missing?Thanks in advance,Don. Keysthemselves do not havevalues. Just add some TRACE() commands to your code into the failure blocks. have a peek here

I'm getting the following error can someone please help me how to get out of it.. Why RegOpenKeyEx is failing with ERROR 87 even with a simple flag of KEY_READ or KEY_ENUMERATE_SUB_KEYS. 2. BOOL IsWin64() { #if defined(_WIN64) return FALSE; // 64-bit programs run only on Win64 #elif defined(_WIN32) // 32-bit programs run on both 32-bit and 64-bit Windows so must sniff BOOL f64 As you can see, in the second case, I have replaced the variable subElement, with actual value.

This newsgroup is about the standard C++ language, which knows nothing about the windows registry. How to explain centuries of cultural/intellectual stagnation? Are the plane and the third dimensional space homeomorphic?

Are you sure the following is correct? I have two tables, I will call them first-half and second-half (of the year) Table: first id jan feb mar apr ----------------------- 2 80 90 70 60 3 50 40 60 Thanks a lot man. I tried it usingTCHARfor the Port string - it gave compiler warningsaboutconversions.

Don Woods 2003-08-20 18:41:29 UTC PermalinkRaw Message Almon,I will keep checking for '2' also, although I amcurrently running it on the emulator and getting '87'.As far as the unicode thing is I don't understand why it works when I open it the first time to count the entries, but not the second time. Beginning with Windows Server 2008, the HKLM\Software\Wow6432Node node is hidden from the RegEnumKeyEx function, although it does not guarantee that an eternal recursion will not occur when trying to directly access Sincethe "Server Port" key does not contain a valuecalled "Server Port", yourRegQueryValueEx call fails with ERROR_INVALID_PARAMETER.RegOpenKeyEx(_T("MyApp")); // You can useRegCreateKeyEx,too, which will first create the key if it doesn'talready exit, and

The PCverion didn't support unicode. https://groups.google.com/d/topic/microsoft.public.vc.language/3rnKFKqIsiw Keys themselves do not havevalues. is HKLM\Software\Wow6432Node\Wow6432Node\Wow6432Node not a visual c++ bug? Thus the rest of stuff is undefined behaviour since you didn't explicity supply the same flag.

#include #include #include //int curl_progress_callback(double ) #define MAX_KEY_LENGTH 255 I have no clue why this is happening. Any idea what I am missing?Thanks in advance,Don.. I reviewed the docs on the parametersandit seemed right.

Please refer to the following two lines of VC++ code printf ("queryRegistrySetting:%s - %s - %s\n", subElement, variableName, variableType); output: queryRegistrySetting: Software\\xx\\xx\\xx\\xx\\xx - Args - EXPAND_STRING long result = RegOpenKeyEx (HKEY_LOCAL_MACHINE, I tried it using TCHARfor the Port string - it gave compiler warnings aboutconversions. How should theunicode string be passed in to satisfy the compiler?Thanks,Don-----Original Message-----Hi,You should also keep your check for "2"(ERROR_FILE_NOT_FOUND)because you still get this behavior when running on theemulator.Also--all [registry] strings are this contact form How is this red/blue effect created?

When I tried storingas unicode, by using a TCHAR variable instead of CHAR, Ikept getting a type mismatch error. I get "There are no more files" error. Read it on msdn. –Abhineet Oct 5 '12 at 6:06 Ok..thanks a lot :-) –user1696837 Oct 5 '12 at 6:06 add a comment| up vote 1 down vote Because Read more 25.10.2016 PVS-Studio for Linux Finally!

Also MSDN says to use "FormatMessage()" to get errors from this one. Why are you recursing to K7RT_RcrsvRegDel instead of to RcrsvRegDel, are they the same function? –Harry Johnston Sep 26 '12 at 21:24 Rather than appending the key names together So why not post to the Microsoft New Server where there are, no joking, 1000's of newgroups devoted to Microsoft technology? abhineet.ayan.verma 20-Sep-12 7:22am Anyways I have checked with the solution you provided and it is still same.

If the subkey was created, but a value wasnever assigned, is it supposed to return '87'? I understand some devices may notactually have the messages available, in which case you'd have to createyour own lookup table..--Michael SalamoneEntrek Software, Inc.www.entrek.comPost by Don WoodsAlmon,I will keep checking for '2' Your Email This email is in use. this opens the registry editor.

The PCverion didn't support unicode. Thank you for the enlightment though :-) –user1696837 Sep 26 '12 at 5:50 @HarryJohnston- Its still the same :-( ERROR 87 –user1696837 Sep 26 '12 at 6:34 Sincethe "Server Port" key does not contain a valuecalled "Server Port", yourRegQueryValueEx call fails with ERROR_INVALID_PARAMETER.RegOpenKeyEx(_T("MyApp")); // You can useRegCreateKeyEx,too, which will first create the key if it doesn'talready exit, and The code works fine for x86 and x64 with VISTA or WIN 7, so i dont think using RegDeleteKey would be causing any problem here. –user1696837 Sep 26 '12 at 6:32

Why are you using two backslashes as the path separator? I reviewed the docs on the parametersandit seemed right.

(I probably use casts more thanI should, soother folks should double-check me here.)Be _very_ wary of mixing TCHAR with anything else.
