- We are currently writing a database client using sockets and XVT's GUI
- (C-version) with the Objects Power Pak 1.
-
- The communications part is ported from HP-UNIX. Using Borland C++ 3.1 and
- its character-mode emulation under Windows, porting the program from
- character-mode terminal to character-mode Windows was fairly straightforward.
-
- But, moving to "Real Windows" using the XVT GUI library (MS-Windows version),
- I get unexpected and unrecoverable errors that I can imagine is caused by
- (normally) blocking calls to WinSock not blocking at all, with the app not
- getting data, calling again, and so on until the app crashes abruptly. Things
- works fine if i use the app gently, not banging to much on the keyboard asking
- for too much data.
- ****************************************************************
- Could this be caused by e.g. a recv() call not being blocked properly as it
- should?
- ****************************************************************
-
- Should I follow Microsofts recommandation, and rewrite the comms part so that
- a non-blocking method is used instead of the traditional blocking method used
- in the original program?
-
- I use
- FTP Software's 2.31 stack
- Borland C++ 3.1 is patched with all patches (1, 2 and 3).
- XVT release is 1.0 for the PowObj's.
-
- Just to detail it a bit more:
-
- An "XVT-table" is being filled with data 20 items at a time. If the user
- expands the table so that e.g. 34 items should be present, then 40 items are
- fetched from the server. If data are not present locally on the Windows
- client, the table asks for data from the comm part of the program. The comm
- part works well if the user is patient when he/she is scrolling slowly, but if
- he/she scrolls hastingly, pounding on the "down" button on the keyboard,
- the table crashes.
-
- Any suggestions?

- I don't know what I am doing wrong (or maybe right). WinMosaic is very
- stable for me. I run the following configuration:
-
-
- 486DX-33 w/16M ram, 200Mb disk
- DOS 5.0/Windows 3.1
- PC/TCP 2.3 (from FTP software, Inc.)
- Microsoft LAN Manager 2.2
- WinMosaic 2.0a2 (file date 2/28/94)
- WPLANY for sound files
- LVIEW31 for GIF's, JPG's, etc.

- The updated TCP/IP Transport files will be placed on FTP.Novell.COM
- and on NetWire/CompuServe in the near future.
-
- Meanwhile, the unofficial collection of fixed files is available in:
-
- sjf-lwp.sjf.novell.com: ~/lwp4dos/winsock/tcp412a.zip
-
- This applies to the TCP/IP Transport found in NetWare/IP, the
- NetWare Client Kit for DOS and MS Windows, and all versions of
- LAN WorkPlace for DOS beginning with v4.1.
-
- See the file "READ412A.TXT" for details.

- Subject: *** WINSOCK INSTALLATION -- HELP, PLEASE! ***
-
-
- THANK GOD FOR THIS NEWSGROUP! I didn't know it even existed...
-
- I've been trying for the last two weeks to install Windows Sockets
- on my machine, and NO MATTER WHAT I DO, it doesn't work. I have tried every-
- thing, and can't go on without assistance...
-
- Situation: I'm running Novell NW3.12, 250user, over ODI (and VLM.)
- I am NOT using LAN WorkPlace. I downloaded a package called LWP168.EXE from
- the Novell archives, and uncompressed its contents into all the right places
- on my hard drive. (The package contains the Novell TCPIP.EXE stack and
- the WINSOCK.DLL and WLIBSOCK.DLL files for it.) I reconfigured my NET.CFG
- files correctly, and the TCP stack loads fine.
- The problem comes whenever I try to run a Windows Sockes program!
- It consistently does the same thing: at startup,
- Application Error
- HGOPHER (or Mosaic, etc.) caused a General Protection Fault
- in module WLIBSOCK.DLL at 000A:0C04.
-
- and nothing I do can change that! I use a program called WinQVT
- (non-Sockets), and I disabled its support files (pktint and odipkt); nothing.
- I tried placing the Sockets DLLs into at least five locations (not COPYING;
- I always had only one copy); nothing. I tried finding any documentation on
- the setup of this thing; nothing.
-
- CAN ANYONE HELP??!! Thanks in advance,
