I have an off-the-shelf app that uses an Access database as its
backend. One of the tables contains a field with an "OLE Object"
datatype. I'm writing some reports against this database, and I
believe this field contains data I need. When I view the table in
datasheet view, all I can see in this field is the string "Long
binary data".
So, I've got the problem of needing to extract data from this
field, but I don't know what format...

I will try to make this short and to the point.
I am reading values from a file using a Binary Reader.
At a particular address I can get a value of , Hex 10 or Hex 01 . (varies can be 30, 20, 02,03 etc.)
I need to keep those values as shown..........10 or 01.
And then split the value........ for instance the 10 becomes 1 or 0. (extract either the 1 or the 0 and display it)
Or in the case of the 01,,,,,,,,,,,0 or 1.( extract either the 0...

Hello.
I am attempting to write binary data from a file to an
OLE Object field, and then write the file back out from
the database. I am reading and writing the files in
binary mode, and using GetChunk and AppendChunk to read
and write binary data from the OLE Object field. I am
using VBA and DAO for this experiment. The OLE Object
field is being used to store Long Binary data.

Hi,
I am trying to get (and transfer over ASP.NET) some encrypted data
from some MySQL fields. Since the data contains many unicode
characters, I tried to get the data as a series of ASCII values,
transfer those numeric values over ASP.NET. I had no problem doing
this on my local computer, by getting the field with "cast(field as
BINARY)" so that on ASP.NET I have a byte array.Then send every
field of array over ASP.Net.

I am working with a sql server database. Due to a database udgrade, sever fields which were integer are now binary(16). These fields are used for joins later in the VB project. The problem I am haveing is that I have no idea how to read in the binary field! Here is the original code(using Visual Studio 08):
strRptPars(iCount).lID = adoOleDbDataReader.GetInt32(i)
Originally strRptPars(iCount).lID was defined as LONG. I tried changing it to...

Hello.
I have a table with a primary key, identity value. In addition to some other fields I also have a computed field to generate a binary identifier for the row based on the identity value (eg. PK ID of 1 would generate a binary ID of 1 (Power(2, -1) = 1), PK ID of 4 would generate a binary ID of 8 (Power(2, - 1) = 8). The problem is that there are +70 rows in this table so the binary ID gets quite large - out of the scope of int, bigint...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
