Michel,

if you don't mind it, I answer you here as this code may help other xHarbour->Harbour switchers :-)

This version of DelFileCache() is properly building with Harbour and Borland.

Antonio,

I tried out your solution. Unfortunately I got these errors :

Error: Unresolved external 'FindFirstUrlCacheEntryA' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ
Error: Unresolved external 'DeleteUrlCacheEntry' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ
Error: Unresolved external 'FindNextUrlCacheEntryA' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ
Error: Unresolved external 'FindCloseUrlCache' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ

What next?

Thanks.

I added this last library.
Where is it for? Everything was going just fine.

Thanks.

Michel,

It solves these externals that you reported:

Error: Unresolved external 'FindFirstUrlCacheEntryA' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ
Error: Unresolved external 'DeleteUrlCacheEntry' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ
Error: Unresolved external 'FindNextUrlCacheEntryA' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ
Error: Unresolved external 'FindCloseUrlCache' referenced from M:\SOFTWARE\JUDAHARB\PRG\OBJ\JUDA.OBJ


How did you solve them ?
regards, saludos
