If you have another table with a record for each client then you can record
the last journal id processed by each client. Then have a purge process
that removes old journal entries based on the min(id).
The problem with this is cross db transactions. What happens if the cleint

Thanks Chris
But it seems a bit long winded
How does this compare with GetTopParentHandle or Screen.ActiveForm.Handle

All this talk of how to find the owning form for an control and no one has
mentioned the standard utility functions GetParentForm and ValidParentForm

You might have to roll your own. If you include a "DT_WORDBREAK or " on

everything else that uses TButtonGlyph (caveat: not sure how that might

How do we go about storing a several files

registry settings). This would upgrade an existing application, with the

Resources can become a problem if you replace a dfm but have
an old .res file hanging about. Try deleting the res files
and see if that helps.

A site has an HP 2100 and my app is by default trying to print to
the wrong tray. (QR2)
By using the QRPreview Printer setup dialog box, we can get it to

Is someone able to send me a snippet of code which demonstrates
how to do this programmatically?
My
Tad advanced for me - besides if the suggestions about including CF/LF work for
others, why does my app not accept them?
Are there other TBitBtn properties that clash with the suggested solutions?
