Mom, a modal loop ate my service messages!

A colleague of mine was using the “modernized” service implementation I wrote about some time ago. His services needs to be notified when a user logs on/off or locks/unlocks the machine. Everything was fine for a while, until he started to complain it worked for a while, but then, “randomly”, notifications weren’t triggered any longer.

Modernize you Delphi Windows application: use Windows 2000 (and later!) services.

No, the title of this blog post is not a mistake. Delphi, including XE7, only implements services using NT APIs obsoleted since Windows 2000. Windows NT was EOLed in 2004, 2000 in 2010, and XP last year, yet Delphi still doesn’t take advantage of the new APIs. What are the advantages? Well, using the “extended” […]

In seguito al crollo della piramide TelexFree, i loro promoter stanno tentando di convincere le vittime che il “business online” – nella loro accezione di “soldi facili e subito facendo poco o nulla” (il vero “business online” è tutt’altra cosa) – è sano e bello.
