Massimo,

ADO knows nothing about RDD Aliases, so they should not be used in ADO expressions

ADORDD is a free and open source RDD. It seems to me as you don't understand the real meaning of that :-)

ADORDD is a contrib folder in both Harbour and xHarbour compilers projects.

It is a great example of the USRRDD (user defined RDDs) use and also a great source for learning ADO. And it has been very usefull for many developers :-)

We should check if it currently works with xHarbour. In that case it would confirm that it is a Harbour new OLE implementation problem.

I recently downloaded the Harbour v2.0 project (with contrib libs), and have been trying to find the ADORDD.lib and USRRDD.lib
without success.

I am wanting to perform a simple test using the ADO xbase convention (ie: use, dbseek(), dbskip()...)

Any assistance is greatly appreciated.

Don,

USRRDD.lib is named as hbusrrdd.lib

Can't find ADORDD.lib in the Harbour 2.0 setup files, but you can download it and build it from here:
http://harbour-project.svn.sourceforge.net/viewvc/harbour-project/branches/harbour-1.0/contrib/rddado/
http://harbour-project.svn.sourceforge.net/viewvc/harbour-project?view=rev&revision=9359
regards, saludos

Antonio,

I am trying to compile the adordd.prg from your reference above, and I recieve the following:

Error: Unresolved external '_HB_FUN_HB_SYMBOL_UNUSED'

Borland Xharb10 with fwh7

Any help is greatly appreciated.

Don,

Please add this line to the beginning of the PRG:
Code: Select all  Expand view

#define HB_SYMBOL_UNUSED( symbol )  ( symbol := ( symbol ) )
 
regards, saludos

My xharbour 1.0 test is not working with the ADORDD - it compiles, however I get a runtime error.
"Error ADOX.Catalog/6 DISP_E_UNKNOWNNAME: TABLES from Errorsys, line: 0"

I am atempting the same test in Harbour 2.0 -
(same source code as with xharbour 1.0 / This source works in Harbour 2.0 without FWH7 )

However, when I compile my code with Harbour 2.0 / Fwh7 / BCC 5.5
I get the following message -
t:\fwh7\include\FiveWin.ch(81) Warning W0001 Redefinition or duplicate definition of #define HB_SYMBOL_UNUSED

This seems to be the opposite of the prior message???

Any ideas?

Don,

That define is provided in Harbour but not in xHarbour, thats why you get the warning in Harbour and the error with xHarbour.
