I am curious what kind of mechanisms other people have
devised to handle errors and aid debugging of their
applications in C++ and Windows. I am NOT talking about
full blown exception handling.

Just simple things like failure of 'new' or file open.
What I am using now is nested conditional constructs.

e.g.
In a constructor for a dialog box with 3 buttons and 1
static text,

{
  button1 = new TButton( ... );

  if (button1) {
    button2 = new TButton( ... );

    if (button2) {
      button3 = new TButton( ... );

      if (button3) {
        label = new TStatic( ... );

        if (label) {
           // SUCCESS
        } else {
           // label failed
              MessageBox( ... );
        }
      else {
         // Button3 failed
            MessageBox( ... );
      }  
    else {
       // Button2 failed
          MessageBox( ... );
    }
  else {
     // Button1 failed
        MessageBox( ... );
  }
}

As you see, this gets messy as the number of components increase.

Also, this does not provide the user, retry, cancel or ignore
options.

Are there any class libraries out there to facilitate this kind
of error handling? Are there mechanisms inherent in C++ or Windows?
Overloading of new in the above case looks like a probable solution?
Send me your replies and should there be sufficient interest I will
summarize and post.

Thanks.
