Podobné chyby při spouštění funkcí HEC-geoHMS

Question

<\/HEAD>Ahoj,<\/P> <\/P> Jsem v ArcMap velmi nový a snažím se použít některé nástroje HEC-geoHMS. Neustále dostávám podobné chyby, ale nemohu rozluštit, co se pokazilo, a nevím, kde začít s řešením problémů. Jediné, co jsem zkoušel, je použití různých verzí DEM pro určité funkce a pokus o ukládání výstupů do různých umístění (složky\/geodatabáze). Může mi někdo říct, co tyto chyby znamenají?<\/P> <\/P> Díky!<\/P><\/BODY><\/HTML>

COM is short for for Component Object Model.  It's essentially a chunk of programming that can be reused for several things.  It's not a GIS-specific term, but a programming one.

COM: Component Object Model Technologies

As to how it applies to the issue you are experiencing, what may have happened is that the .COM file that HEC-GeoHMS is trying to access is no longer located where HEC-GeoHMS is expecting it to be, thus the error.  If that is the case, one possible solution may be to find out which application provides the .COM file it is trying to access and reinstall it.  I don't know if that means one would have to reinstall HEC-GeoHMS, ArcGIS, or a different application, though, to get the file back where it belongs.

All of my knowledge and experience with ArcGIS started 3 months ago and is fairly superficial. Could you explain what a COM module is, where it is, what it does?

This part I don't know - I have not used HEC-GeoHMS myself.

My only guess would be that maybe HEC-GeoHMS is missing one of the COM modules?  However, that is just a guess.
