Help with PDOX45 on Win 2000

[JLRPR]

My company laptop has recently been upgraded to Windows 2000, and My PDOX45 (DOS) is not running adequately. While I’m able to boot up, when I run a query that results in an answer with more than 1,000 records, I get a “Resource Limit Exceeded” Message, and the program quits. I’ve gone into the configuration and the Private Directory and everything seems to be in order.

…Any help would be greatly appreciated.

Make sure you have plenty of hard drive space (at least 50-100mb free for a large query). If it's running out of memory, check your windows shortcut settings for the Paradox icon.

Right click the icon and choose Properties. Under the memory tab, try the following settings:
Conventional Memory: Total: Auto
Initial Environment: 4096
EMS memory: none
XMS memory: 8192
Uses HMA (not checked)
MS-DOS Protected mode memory: 8192

Let me know if this helps at all.

Dan,

Thanks for your prompt reply. I tried your suggestions but still get the same "Ran out of diskspace" message. I have 13GB of disk available so I'm not sure why it's giving me this message.

Any other suggestions would be greatly appreciated.

Are you running the application on a network, or just on the laptop?

JLRPR,

PMFJI, but you're talking about Paradox/DOS 4.5, which was published when the largest hard drive was less than 2GB.

What you may be seeing is a "roll over" effect stemming from "overflow," meaning the number of avilable bytes is so large, it's overflowing the space allocated for it. In turn, Paradox/DOS is only hearing about the bits that are actually saved, meaning it doesn't know about that scads of free bytes that are still out there.

You might consider a little tool called LesSpace (

http://www.kennedysoftware.ie/lesspace.htm)

which tells older applications (like Paradox/DOS that "yes, there's enough space available, please carry on with the operation.&quot

OK; it's a bit more technical. Details are on the site. Note that LesSpace *is* shareware; if it's useful, please register it.

Hope this helps...

(And, no. I don't get a kickback. I've used LesSpace before and it works like a charm if that's your problem. So I recommend it. YMMV.)
