Microsoft Active/X Internet Controls
BETA2:  Notes/Issues/Workarounds

Welcome to BETA2 of the Microsoft Active/X Internet Controls!  Contained within this 
document are notes to users of BETA1 of the Microsoft Active/X Internet Controls, 
known Issues that you will run into and have questions/bug reports about (but we already 
know about) and finally Workaround solutions that have been developed for previously 
reported control issues.

Some of the previously reported issues that have been addressed in BETA2 of the 
Microsoft Active/X Internet Controls are:

  Improved operational support for users of Microsoft Visual C++ 
  Improved handling of control re-entrancy issues (breakpoints in asynchronous process events)
  Overall control stability improvements
  Some fit and finish improvements

P.S. - If you were previously using BETA1 of the Microsoft Active/X Internet Controls, 
you MUST read the following Setup procedure section!!!  


Setup procedure (IMPORTANT TO READ):
  If you are running BETA1, RUN UNINSTALL prior to installing BETA2!
  Uninstall does not mean merely deleting the files, it means running the uninstall 
  application from the ICP Program Group (WinNT) or from within Control Panel 
  Add/Remove Programs Applet (Win95)
  Any application written with the BETA1 controls will not load in BETA2 properly 
  unless one of the following steps are completed:
 
1) Run the supplied CONVERT.EXE program against the Visual Basic 
   project file (source code is included as well) OR,
 
2) If you REALLY want to perform the following steps manually:
   In any Visual Basic project file, replace the following BETA1 
   GUIDS (the following represents all one line, not two):

  In any Visual Basic form file, replace the following BETA1 
  ProgIDs

HTTPCTLib.HTTPCT HTTPCT1 
NNTPCTLib.nntpct nntpct1 
POPCTLib.POPCT POPCT1 
SMTPCTLib.smtpct smtpct1 
FTPCTLib.FTPCT FTPCT1 

  With the following BETA2 ProgIDs

HTTPCTLib.HTTP HTTP1 
NNTPCTLib.NNTP NNTP1 
POPCTLib.POP POP1 
SMTPCTLib.SMTP SMTP1 
FTPCTLib.FTP FTP1



Known Issues:
All
  You must register "Microsoft Internet Support Objects" via the 
  Tools.References... menu selection for all controls except WinSock.

WinSock
  UDP does not support broadcast address (IP Address: 255.255.255.255)
  Opening a common dialog with UDP in the project will prevent the 
  DataArrival event from firing


HTML
  There are known rendering problems with EMWAC Web server
  There is no support for proxies
  Printing the HTML page has not been implemented
  The ability to select text has not been implemented


HTTP
  There are known downloading issues with EMWAC Web server
  There is no support for proxies


FTP
  There is no support for proxies


NNTP
  Secure news groups on news servers that do not make the AUTHINFO 
  request will not currently authenticate.




Work Around Listing:
WinSock
  With TCP and UDP you cannot send an embedded Null character in a string.  
  You must use a byte array.  Sample source as follows:

Dim b() as Byte
s$ = "Test" & Chr$(0) & "Test"	‘alone would result in only "Test"
b = s$
TCP1.SendData b
  A simple replacement for PING (with both TCP and UDP) is to connect and 
  send to the standard ECHO Socket port (which is usually 7)


HTML
  For file based URLs use the following convention:
  file:///c:/dir/file.htm
  file://localhost/c:/dir/file.htm
  file:///c:\dir\file.htm
  file://localhost/c:\dir\file.htm


FTP
  There are known issues with Microsoft IIS and the DirItem object.  
  Workaround is to use the DocOutput event rather than the ListItem event.
  GetFile always appends to LocalFile currently.  Workaround is to look for 
  icDocBegin in the DocOutput.State property and delete the LocalFile if it 
  exists.

Sample Application Listing
==========================
WinSock
  Voice Chat sends recorded voice over a TCP/IP link.
  Requires two machines

  Adjust the microphone volume for distortion if occurs

  Requires a valid HTTP server or file HTML source
FTP

  Requires a valid FTP server 


NNTP
  Network News Explorer client program
  Requires a valid TCP/IP (PPP OK) network connection
  Requires an NNTP source (service provider provides)
