Cress does not work in Vista

At this moment Cress does not work in Vista. We are working on it, but this takes some times (there is a budget problem). Because Vista has no other added value that increasing the profit of Microsoft, we suggest you downgrade your system to XP. This gives less problems, works faster and requires less memory.

Are there upgrades available ?

Available is a new table of contents, as well as some new routines. You can download the new table of contents in English or in Dutch. Replace the old .tbl file in the RWS cress directory by the new one. Some new routines can be downloaded from Upgrade2003. For installation instructions see the enclosed Readme-file.

I can't install Cress, because I  see only installation in Dutch and no installation in English?

Don't worry about the Dutch language; after Installation you can select any language. The procedure is as follows:

• Unpack the Zipfile (rwscressEN.zip) into a temporary directory; you see that now a deep tree has been constructed in this directory; open all folders until you arrive at the folder DISK1
• Click on Setup.exe in this folder
• Click on "Volgende" (= Next)
• Fill in appropriate user names
• Select appropriate place for the program (we recommend to use the default), and click on "Volgende"
• Select Pictogram place (the default name is "Rekenregels", you may change this to "Cress" if you like, continue by click on "Volgende"
• Check settings and click "Volgende"
• Installation starts now, wait some time
• At a certain moment a registration box appears, writing many lines; This stops when you se "KLAAR...."; close then this box by clicking on "sluiten" (=close)
  Note: you may also use the program "registreer.exe" for registration, this program is english, use as file the file "registreer_all.txt in the folder "registreer"

Remind that for windows 2000 and NT it my be useful to update some files, see below

When I try to make a graph using the "sensitivity" button, the program stops with a message "class not found" ?

This problem has been encountered on computers with windows 95. The problem is that Cress uses a Microsoft-routine MFC42.dll. You may download this dll from this site. You should place the dll in the windows/systems directory on your computer and run the program "registreer", which is in your Cress directory. Click button "register" and select the file "registreer_all". You see that now all dll's are registered. At the end of the registration procedure, you should see that also the routines UIgraph, UIframe and UItable are registered. After this is done, Cress works as it should.

After downloading and installation I cannot run the program, the program gives the message that there are no rules (may occur in W2000, NT, XP)

This is caused by the fact that the version you have downloaded requires administrator capabilities for the Registry. This can be solved as follows:
- download a new exe-file: rekenregels.exe and overwrite the existing file in "program files\rws cress\"
- download a new bpl-file: rr_basis_5.blp and overwrite the existing file in WINNT\system32\.."
- take care that the file "program files\rws cress\strings.asc" is not write-protected for the user; in case the user has no writing rights on this file, he will not be able to change the language of the package. 
(Executing the above steps may require administrator capabilities, depending on the setting of your system)
Both files can also be downloaded as zipfile.

The help is only in Dutch, how to find Help in English

Unfortunately the English help is not yet completely ready. You may download the HelpUk file. The contents of this file can be placed in the directory ...RWS cress/regels, overwriting the existing files. A number of Dutch files are replaced by English ones. The original Dutch help will remain in the directory RWS cress/registreer. Not all files are available in this way. The other files are only available as .rtf files, and can be downloaded from UKhelpRTF. This zipfile contains the Helpfiles only in rtf-format, and not in WinHelp format. This means that you cannot access them via the Help button in cress, but have to access them outside Cress, using Word. 

As an alternative, you may also go to: http://www.kennisbank-waterbouw.nl/CressHelp/Content.htm where you can find help in detail for various routines. 

Help does not work in the IHE version of Cress

At a certain moment Microsoft decided no longer support their own help-system in newer versions of VisualBasic. Therefore the help function does not work in the CressWin (IHE) package. However you may download the help separately and run it separately
