C++ RegCreateKeyEx成功了，但是注册表并没有这一项

C++ - RegCreateKeyEx success but without result

Could anybody tell me what's wrong is with this code? There is no errors. Everything returns ERROR_SUCCESS but in register can't see any changes.

void
Utils::writePath(LPCTSTR data)

{

HKEY hkey;

DWORD dwDisposition;

if(RegCreateKeyEx(HKEY_LOCAL_MACHINE,

TEXT("SOFTWARE\\aaTestCompany\\testApp"),

0, NULL, 0,

KEY_WRITE, NULL,

&hkey, &dwDisposition) == ERROR_SUCCESS)

{

long setRes = RegSetValueEx (hkey, "testPath", 0, REG_SZ, (LPBYTE)data, strlen(data)+1);

if (setRes == ERROR_SUCCESS) {

printf("Success writing to Registry.");

} else {

printf("Error writing to Registry.");

}

RegCloseKey(hkey);

}

else

MessageBox(NULL,"error","",0);

}

 

【解决方法】

As the application is 32-bit on a 64-bit OS the registry key will actually be created beneath HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node.

See 32-bit and 64-bit Application Data in the Registry.
