Error reading default value with wxRegKey Topic is solved

[Laurent22300]

Hello,

I'm using wxRegKey to read some value in the registry. This is what I'm doing:

Code: Select all

wxRegKey* regKey = new wxRegKey(_T("HKEY_CLASSES_ROOT\\.test"));

if (regKey->Exists()) {
  wxString defaultValue = regKey->QueryDefaultValue();    

  if (defaultValue != wxEmptyString) {
    // etc.
  } 
}

It works well in most case, except when the default value is undefined (it appears as "Value not set" in regedit). In that case, wxWidgets outputs a system error, which says "Can't read value of HKCR\\.test Value not set".

So is there any way to prevent this error? For example, is there any way to check if the default value exists before querying it? I've searched the help file but couldn't find anything. Any ideas?

Thanks,

Laurent

I guess a solution would be to simply disable the error message. Is it possible to do that?

For information, the message is generated by wxLogSysError.

temporarily create an instance of wxLogNull
