BC 5.01 is Shipping

(August 29, 1996) Version 5.01 is shipping. Several users report getting the 5.01 CD. In the US the CD will be shipped automatically to registered users of 5.0 and is free of charge. In other countries check with your local Borland representative. (In Canada there is a $15 charge for shipping and handling, for instance.) 5.01 includes these features:

MFC 4.1
Ability to use VCL (Visual Component Library) in both OWL and MFC apps
Active X container support
TTreeView emulated for 16-bit
Free copy of Delta Point's QuickSite (web creation software)
Lots of bug fixes

Be sure to read INSTALL.TXT on the CD or click here for a summary.

Important Information (5.0 Release)

There are a couple of issues common to all users that need to be emphasized.

Using 4.x Projects under 5.0. Read this!
BC++ 5.0 Practical System Minimums.
Frequent IDE Crashes.
If All Else Fails....

Please do not e-mail us for technical support. For technical support use the BCPPLIB and BCPP forums on Compuserve, call the Borland International Technical Support line, check out the internet newsgroups or subscribe to the OWL mailing list (free e-mail list).

BC++ 5.0 Practical Minimum System Requirements

The BC++ 5.0 system requirements say that 16MB RAM is the minimum. Although 5.0 will run on 16MB it is not optimum by any means.

Under Windows95 24MB RAM should be considered a practical minimum. Moving from 16MB to 24MB should result in speed performance improvements of 4 times or more. Adding more memory will certainly continue to improve speed but not as much as the initial move from 16 MB to 24MB.

Under Windows NT you should add 8MB above the requirements for Win95. Users report the best performance on NT with 48MB and above.

It should be noted that in either case a badly fragmented hard drive can increase compile and link times by a fair amount. Clean up your hard drive and watch your build times improve.

If All Else Fails...

If nothing on this page solves your problem then take these drastic steps (in order of simplicity):

1. First be sure that you have applied the patches.

2. Close the IDE and then delete the .dsw and .csm files for your project and the bcwdef.* files in \bc5\bin. Also delete the *.spx files in the \bc5\scripts directory. Restart the IDE.

3. Rebuild your project from scratch in the 5.0 IDE.

4. Check your system configuration carefully. Be sure you have the latest video drivers installed for your video card.

5. Try to update the registry entries.

6. Uninstall and reinstall 5.0 and then apply the patches.

7. Uninstall Windows, reinstall Windows and then go to step #3.

Although uninstalling and reinstalling Windows is a colossal pain it is a good idea from time to time. When you install and uninstall programs a number of times things can lurk in the registry, system.ini and/or win.ini that can mess up your system.
