Technical Support Frequently Asked Questions

Q: After installing Hydrodata for Windows, I have decided I want to install it somewhere else, but the application keeps using the original installation path. How do I change the directory?

  1. Delete the directory where you installed the discs.
  2. Delete the file hydro.ini (if you are using version 3.1x) or newhfw.ini (if you are using version 4.0x). The ini file is in the \windows (or \winnt) directory.
  3. Reinstall the disc(s) and specify another location.
Remember, the application will not work if you install to a directory whose path contains a directory with more that eight characters in its name (such as 'Program Files').

Q: When I start my Hydrodata for Windows, I get an error saying "In attempting to append filename to the stations database, an error occurred. Couldn't find object field" (where filename is some .mdb or .dbf file and field is some simple string.
This usually indicates one of two problems:

Q: When I start my Hydrodata for Windows, I get an error saying "SQL error: Couldn't find 'e:\dbase\stninfo.mdb'."(where e is some drive letter).
This usually indicates that you are using Hydrodata for Windows, version 4.0 but are looking at a disc that is incompatible with version 4.0. Only the 2000 update discs will work with Hydrodata for Windows, version 4.0. Check the disc in your drive and be sure it is the proper one. You can verify your version by clicking on Help-About from the Hydrosphere for Windows main menu. The version is at the top of the Help box.

Q: When I click on a station in the Station Window, the Parameter Window shows a different station name. What's wrong?
Most likely, you are using a CD disk whose manufacturing date does not match the date on the database files installed for that product and region. Compare the dates on the DBF files located in the disk's directory (see the User's Manual for a discussion on the naming convention for disks) and the dates on the DBF files located in the DBASE directory on the CD. These should be the same. This usually occurs when a new disk is not installed over last year's data.
If the files are not the same date, you can force the application to reference the proper files by using Options-Database Locations. Select the CDROM option for the two choices for the disk/region that is problematic.

Q: I tried to print a Plot but it came out with the labels and titles in the wrong place. What's wrong?
This can be caused by a problem between LaserJet III printers and the Windows interface. To fix the problem, you need to tell the printer drive to "print true-type as graphics". Open Control Panel from Program Manager, select Printers, select Setup, and then select "Print TrueType as Graphics". This option may not be enabled with some HP printers if the "Graphics Mode" is not raster.
Selecting this option will significantly slow down all other printing operations from Windows, so it is not recommended that you leave your printer driver in this configuration after you are finished printing plots.

Q: I have several Hydrosphere discs and I installed the application from one of them, but the application doesn't recognize the other discs. What's wrong?
Each disc must be installed separately. While the application software is the same for all discs, each database has its own set of database files and must set up its own directory for those files. The installation process creates the directory and copies the necessary files for each disc.

Q: I have a CD drive that is located on the network (not on my local work station). The application keeps telling me that it doesn't recognize the disc, even though it is a Hydrosphere data disc. What's wrong?
Prior to version 4.0x, Hydrodata for Windows was designed to work with a local CD reader. If you are using older Hydrosphere discs that use version 3.x of Hydrodata for Windows, you will need to contact hydrosphere to obtain network-aware software and perhaps a network liscense.
If you are using our latest discs (update 2000) with version 4.0x of Hydrodata for Windows, this message may indicate that you have not configured the network CD drive to look like a "root" drive. The software expects to find files in a certain location off of a single "root drive" letter. You will have to configure your remote CD drive to be accessible as a single drive letter. How you do this will depend on your network software.
Remember also, if you have a local CD drive, the software will, by default, try to read a disc in that local drive. You will have to tell it where the network drive is, either by using the File-Select CD Drive command from Hydrodata for Windows menus, or by altering the Properties for the Hydrodata for Windows icon so as to specify the drive letter in the Target line of the ShortCut tab in the Properties window supplied by the Windows operating system.
For example, if your remote drive is designated as "H", and you have used the default path for installation, the Target line would be "c:\hydro\hfw.exe". Simply add the drive letter onto the end of the line, including a space character before it: "c:\hydro\hfw.exe H". This will cause the software to look for the CD on drive H when it starts up.
If you are using your Hydrodata discs on a network and more than one user may be accessing the data simultaneously, you should obtain a multi-use license. Please contact Hydrosphere if you have any questions about this.

Q: I started Hydrodata for Windows and I got an empty Stations Window and a SQL error saying "Unable to locate PARMLIST.DBF". What's wrong?
This usually happens when a Parameter Selection was done in a previous session and the Options-Save Current Selection command was issued. For some reason, the special file PARMLIST.DBF cannot be found by Hydrodata. You can reset the application by issuing the Select-Reset Selection command. This will cause Hydrodata to load all the data for that disc. You should then issue the Options-Save Current Selection command to reset Hydrodata for the next time you use it.
