Re: Callback function for failed disk write?

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Suffice to say that, for you purposes, in a high-level language like VB or
VB.NET, just call the WriteFile equivalent function. If it fails, check the
error code; if it succeeds, assume that the data was written to disk. The
OS will fail a write immediately if there is not enough disk space.
