The information in this article applies to:
- Microsoft Excel for Windows 95 7.0a
- Microsoft Excel for Windows 5.0c
- Microsoft Query
This article was previously published under Q149773 SYMPTOMS
If you use DDERequest to retrieve a list of tables from a Microsoft Access
database, you may receive one of the following error messages, depending on
which version of Microsoft Excel and Microsoft Query you are using:
Microsoft Excel version 5.0 or 5.0c and Microsoft Query version 1.0
MSQUERY caused a general protection fault in module MSQUERY.EXE
at 0017:00003537
Microsoft Excel version 7.0 and 7.0a and Microsoft Query version 2.0
MSQRY32 caused an invalid page fault in module MSQRY32.EXE
at 0137:0047e661
CAUSE
You may experience this behavior, if the following is true:
- You are using the DDE request statement:
<Table Array> = DDERequest(<Channel>, _
"Tables/<DataSourceName>/<User>/<Database>)"
Where <Table Array> is the name of the variable assigned to hold the
returned value, <Channel> is the DDE to Microsoft Query channel
variable, <DataSourceName> is the specified Data Source Name, <User> is
the specified User Name, and <Database> is the specified Database Name.
-and-
- If at least one of the following is true:
- You are using the Microsoft Access 2.0 ODBC Driver from the ODBC 2.0
Driver Kit, the ODBC 3.0 Driver Kit, or the ODBC Drivers supplied
with Microsoft Access 7.0.
-or-
- You are using the Microsoft Access 7.0 ODBC Driver from the ODBC 3.0
Driver Kit or the ODBC Drivers supplied with Microsoft Access 7.0.
WORKAROUND
You can avoid the error symptoms by leaving the User argument blank. The
Table data will be returned based upon the currently connected User:
<Table Array> DDERequest(<Channel>, _
"Tables/<DataSourceName>//<Database>"
where <Table Array> is the name of the variable assigned to hold the
returned value, <Channel> is the DDE to Microsoft Query channel variable,
<DataSourceName> is the specified Data Source Name, and <Database> is the
specified Database Name.
If you use a Table Array variable of TableArray, a Data Source Name of
"Access 7.0 NWind", and a Database Name (location) of
C:\Msoffice\Access\Samples\Northwind, then the DDERequest statement would
look similar to the following:
TableArray = DDERequest("Access 7.0 NWind"// _
& "C:\MSOFFICE\ACCESS\SAMPLES\NORTHWIND")
REFERENCES
For additional information about the syntax of this DDERequest statement,
see the "Microsoft Query 1.0 User's Guide," Chapter 9, "Using Dynamic Data
Exchange with Microsoft Query."
