What happens if regcreatekeyex fails in winerror?

What happens if regcreatekeyex fails in winerror?

RegCreateKeyEx failed code 5. Access is denied. is commonly caused by incorrectly configured system settings or irregular entries in the Windows registry. This error can be fixed with special software that repairs the registry and tunes up system settings to restore stability

Windows RegCreateKeyEx () returned error code 5. The error occurs because java.util.prefs.WindowsPreferences is trying to save information in HKEY_LOCAL_MACHINESoftwareJavaSoftPrefs instead of under HKEY_CURRENT_USERSoftwareJavaSoftPrefs.

RegCreateKeyEx windows() returned error codes 5. . Stack trace: Not applicable. The problem occurs when the application is run as a non-administrator user, presumably just logged on to a Windows system that does not have the HKLM\Software\JavaSoft\Prefs registry entry.

It seems that if the RegOpenKeyEx argument remains NULL, error law 2 is returned. EDIT 2: I’ve explored several solutions including using the TEXT() function on the subkey and changing the permissions to KEY_SET_VALUE, but I’m still getting a match error. I also tried RegCreateKeyEx.


The winreg.h header defines RegCreateKeyEx as a powerful alias that automatically selects the ANSI or Unicode version of this application based on the normally constant UNICODE preprocessor definition. Mixing the use of an encoding-independent alias alias with code that is not encoding-independent can lead to incompatibilities that result in compile-time execution or possibly errors.

I used RegCreateKeyEx application from Win32 (VisualStudio 2008) 64 for bitwindows (project made with x64 concentrate). He managed to create a register of records. Now I have a DLL file (created project along with x64 target) that also wants to manifest a registry entry, but the DLL may return error code 5 (yes! This is definitely a sign of denial of use).

The RegCreateKeyEx function key does not create any value. An application can use our RegSetValueEx function to set key values. The regcreatekeyex function creates all the missing secrets in the specified path. It is entirely possible for an application to use these methods to generate multiple keys at the same time.

What is the handle of the regcreatekeyex function?

This is returned by the RegCreateKeyEx function, or possibly even RegOpenKeyEx, or it could be one of the following predefined tactics: Name one of the subkeys that the experts think this function opens or creates. The specified subkey must be a unique subkey of the key uniquely identified by the hKey parameter; In this registry tree, it can go up to 32 levels.
