wxFileDialog open in MyApp::OnInit() error

I am trying to open a wxFileDialog in MyApp::OnInit(), but I end up with an error message saying "no matching function for call to ‘wxFileDialog::wxFileDialog(MyApp* const, const char [12], const wxChar*&, const wxChar*&, const char [6], )".

MyApp::OnInit()
{
    wxFileDialog dialog2(this, _T("open a file"), wxEmptyString, wxEmptyString, _T("*.csv"), wxFD_OPEN);
    dialog2.ShowModal();
    ... open the file and then do something ...
}

The idea is to allow the user to open a config file before the program starts. Can anyone offer some advice to this problem?

Thanks.

According to wxWidgets documenation, the macro _T() is different from _(). So, try just with _ while passing the arguments. 

wxFileDialog dialog2(this, 
                     _("open a file"), 
                     wxEmptyString,
                     wxEmptyString,
                     _("*.csv"), 
                     wxFD_OPEN);

The problem is your first parameter, the dialog parent, it expects a wxWindow* but you are passing a MyApp*. Since you don't have a parent just pass NULL instead.

wxFileDialog dialog2(NULL, _T("open a file"), wxEmptyString, wxEmptyString, _T("*.csv"), wxFD_OPEN);
