Vergelijkbare fouten bij het uitvoeren van HEC-geoHMS-functies

Question

<\/HEAD>Hallo daar,<\/P> <\/P> Ik ben heel nieuw met ArcMap en probeer enkele HEC-geoHMS-tools te gebruiken. Ik krijg steeds vergelijkbare fouten, maar ik kan niet achterhalen wat er misgaat en weet niet waar ik moet beginnen met het oplossen van problemen. Het enige wat ik heb geprobeerd is het gebruik van verschillende DEM-versies voor bepaalde functies en het proberen op te slaan van uitvoer op verschillende locaties (mappen\/geodatabases). Kan iemand mij vertellen wat deze fouten betekenen?<\/P> <\/P> Bedankt!<\/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.
