The files are installed in the following directories:
C:\SQL\SQLVBXDB C:\SQL\SQLVBXDB\SAMPLE42 C:\SQL\SQLVBXDB\SAMPLE10
SQLVBXDB.VBX X
SQLNDEF.BAS X
SQLVBXDB.LIC X

D2HNAV.EXE windows directory
D2HLINK.DLL windows/system directory
D2HNAV.HLP windows directory

The file SQLVBXDB.LIC is the licence file. This file must reside in
the same directory as the file SQLVBXDB.VBX. This file is required if the
SQL-Sombrero/VBX for DB-Library is to be used in developing an application.
The SQLVBXDB.LIC file is not required for an application that is distributed
as an EXE file. See the inside cover of the manual for further details on the
.LIC file.
The file SHOWMOD.EXE is provided as an extra. This program will show
the modules which are currently loaded in the system. This file if chosen
from the list of components is loaded into the WINDOWS directory. Use of the
program is very simple. There is a list of currently loaded modules.
Selecting a new entry in the list causes the information about that module to
displayed to the right. This program is most useful to ensure that modules
loaded are the correct module. This information can be determined from the
directory from which the module is loaded and in some cases from the
description of the module. Some manufactures of software do not use the
version information for their modules. In this case the string "No data
available" is displayed.

If a SQL-Sombrero/VBX call does not seem to work as described in
the manual please check the online help file. This file will always be
the most current information about SQL-Sombrero/VBX.

*************************************************************************
Here is the list of enhancements and changes to SQL-Sombrero/VBX since
Version 1.0.0
-------------
March 16/1995 - (Version 1.0.4)
This version contains the following fixes:
The routines to handle image and text data have been updated. The SqlWriteText
function has been fixed. In previous versions this function would report as
not being found.
In certain circumstances if multiple applications using SQL-Sombrero/VBX were
loaded at the same time, a GPF would occur during the callback for error and
server messages. This has been fixed in version 1.0.4.
A new online help file is provided with fixes to the manual. The information
in the online help is the most recent information about SQL-Sombrero/VBX.
-----------
Jan 27/1995 - (Version 1.0.3)
This version contains the following fix:
The routines SqlDateCrack, SqlRpcParam and SqlRPwSet could cause a GPF
if an empty string "" was passed as a parameter.
If any empty string is passed to SqlDateCrack the routine will proceed
as if the string "Jan 01 1900" was sent. This is standard DB-Libray
functionallity.
If an empty string is passed to SqlRPwSet then the remote password will be
set to the empty string.
If an empty string is passed to SqlRpcParam the input parameter will be
considered as a NULL parameter.
-----------
Jan 17/1995 - (Version 1.0.2)
Fixed function SqlRpcParam. This function would only work correctly for
datatype SQLCHAR. It now correctly converts the string supplied to the
correct datatype. The documentation in the manual states that the second
parameter for this function is the stored procedure name. This parameter
is the parameter name for the function. This parameter is optional and
will be ignored by DB-Library if an incorrect name is supplied. This is
a "by design" behavior according to SYBASE.
-----------
Dec 13/1994 - (Version 1.0.1)
The added functions are and are not currently in the SQL-Sombrero/VBX
documentation.
*******
SombreroVersion$()
Returns the version of SQL-Sombrero into a string
Syntax
ver$=SombreroVersion()
Remarks
This function can be called at any time.
*******
SqlFreeLogin
Frees the memory allocated by SqlLogin% for a login record.
Syntax
SqlFreeLogin(loginrec%)
loginrec%
A login record. The value of loginrec% is returned by
SqlLogin%.
Remarks
You can call SqlFreeLogin immediately after you call SqlOpen
or you can use the same login record for multiple calls to
SqlOpen. Call SqlFreeLogin when you are completely finished
with a login record.
*******
SqlTabSource
Returns the name and number of the table from which a result column
derives.
Syntax
SqlTabSource$(sqlconn%, column%, tabnum%)
sqlconn%
A SQLáServer connection. The value of sqlconn% is returned by
SqlOpen%.
column%
The number of the result column. Column numbers start at 1.
tabnum%
An integer variable to receive the table number. Many Visual
Basic for SQLáServer functions that operate in browse mode
accept either a table name or a table number. If SqlTabSource$
returns an empty string, tabnum% is set to --1.
Returns
A string containing the name of the table from which a result column
derives. If an empty string is returned, it means one of the following:
-The SQLáServer connection is inactive. This is an error that
invokes an application's error handler.
-The SELECT statement does not contain the FOR BROWSE clause.
-The column number is not in range.
-The column is the result of an expression, such as MAX(colname).
*******
SqlTabName
Returns the name of a table based on its number.
Syntax
SqlTabName$(sqlconn%, tabnum%)
sqlconn%
A SQLáServer connection. The value of sqlconn% is returned by
SqlOpen%.
tabnum%
The number of a table. Table numbers start with 1. Use
SqlTabCount% to find out the total number of tables involved in
a particular statement.
Returns
A string containing the name of a specified table. This string is empty
if the table number is out of range or if the specified table is a
SQLáServer work table. For a description of work tables, see
SqlTabCount%.
