Delphi 7 SDAC 8.0.4 Error

Post by swright » Mon 12 Feb 2018 11:39

Delphi 7

I upgraded from 8.0.2 to 8.0.3 and had complaints that the application was going non responsive never to return.

I managed to recreate this in the debugger a few times and it appeared to be calling WaitForMultipleObjects, like it is waiting for a thread to terminate that never does. (I cannot be sure at this point that this is a problem with SDAC).

So I Installed 8.0.4

On startup i get the error

"The procedure entry point @Crthread@initialization$qqrv could not be located in the dynamic link library sdac70.bpl"

For now I have reverted to 8.0.2 to see how it goes.

Regards

Steve

It seems that there are some old SDAC units on your computer. To solve the problem, try to perform the following steps:
- close Delphi 7;
- uninstall SDAC;
- remove all the files dclsdac*.bpl, dclsdacfmx*.bpl, sdacfmx*.bpl, sdacvcl*.bpl, datasetmanager*.bpl, dclcrcontrols*.bpl, dcldac*.bpl, dacfmx*.bpl and dacvcl*.bpl from your computer (please make sure that there are no such files on your computer);
- install SDAC;
Please follow our recommendations and inform us about the result.

NonBlocking is a feature of SDAC DataSet(TMSQuery and TMSTable) that is used to retrieve records in a separate thread. Would you please specify if you are using this feature in your application?

Thanks for the reply.

Those files were not present, However I found the problem, a component using sdac needed recompiling.

I am not using the NonBlocking option.

Please specify whether you still have any unsolved issues with SDAC 8.0.4. If so, then please provide us with a sample demonstrating the issue, as well as the script for creating the table.
