RegSetValueEx not working!!!???

I am making an application that works like a windows registry
I am almost done, I can't just find out why, I got this bug which I did not encounter before. My codes has been working for the past weeks, now, it no longer works... :( :( :(

Help me find our why...

I created a new key:
HKEY_CURRENT_CONFIG\System\New Key #1

The key is created successfully. Then, under ...New Key #1
I created a new value, New Value #1 of type REG_SZ and no data yet.
New Value #1 is successfully created using the following codes:

Code:

CString csREG_SZ_val = ""; RegOpenKeyEx( m_hKey, csSubKey, NULL, KEY_ALL_ACCESS, &m_hSubKey ); RegSetValueEx( m_hSubKey , csValName, NULL, REG_SZ, (LPBYTE)csREG_SZ_val.GetBuffer(csREG_SZ_val.GetLength()), csREG_SZ_val.GetLength()+1);

That creates "New Value #1" of type REG_SZ under HKEY_CURRENT_CONFIG\System\New Key #1

I know that it is created because, I opened windows registry and I can see that value under that key.

Here's the BUG!!!
When I rename New Value #1 to New Value #2, it is no longer seen using RegEnumValue.

How did I rename the value? Here:

Code:

// Open the key that contains the value being renamed RegOpenKeyEx( m_hKey, csSubKey, NULL, KEY_ALL_ACCESS, &m_hSubKey ); // Querty the name size and data size RegQueryInfoKey( m_hSubKey, NULL, NULL, NULL, NULL, NULL, NULL, NULL, &dwValNameSize, &dwValDataSize, NULL, NULL); // allocate space for value data szValData = (BYTE*)malloc(dwValDataSize+1); // Get the type, and the data RegQueryValueEx( m_hSubKey, csValName, &dwValNameSize, &dwType, szValData, &dwValDataSize ); // Set value using new name RegSetValueEx( m_hSubKey, csNewValName, dwValNameSize, dwType, (CONST BYTE*)&szValData, dwValDataSize ); // Delete previous value name RegDeleteValue( m_hSubKey, m_csValName);

After that, csNewName does not appear under HKEY_CURRENT_CONFIG\System\New Key #1!!!

Was it save somewhere else? Or it was not saved at all? I am not encountering any error messages. I said its a bug because, it is expected that the renamed value must still be present.

Please help me!!!
