Memory issue with DOS based application

[brooza]

Hi,

I'm running a DOS based application on Windows XP. Opening the program and navigating through the application menu's is not a problem. The brick wall I've hit is when I try to print within the DOS application. I get the following error message: "NOT ENOUGH MEMORY. Press Any Key to Continue".
I had Windows 7 installed on this same PC a couple of days ago and I was able to print. I've had to go back to Windows XP for other reasons and now I've hit this blocker. I've tried doing the same thing on another XP and vista machine and I get the same error.

Not sure if the following will assist:

------------- --------------------- -------------

If there is any other information that is required, let me know and I will get it.

Thanks

Your mem /c output looks much like what I get from an XP box here, except:
- You have a TSR PRN2FILE resident which I don't (likely used for DOS printing)
- Yours shows a lot of memory (Extended and XMS) available. Mine is under 2 meg for both.

Some DOS programs can't deal with too much memory, and the symptom is often a bogus insufficient memory error. Try limiting the extended memory available to the app.
(ref: "Configuring the DOS Environment"

)

Other than that, possibly insufficient DOS file handles; try adding a line "files=50" to the end of c:\windows\config.nt to allow for 50 handles.

Did you change permissions at all when you reinstalled? That not enough memory error can also be because there is insufficient 'write' rights wherever the app is trying to write a temp file.

Another way of doing this is through VMs. Download something like VMWare. Install XP but only give it something like 64 or 128Mb RAM. Then try running your program from there.

Alternatively install DOS or Win95/98 in the VM and run with that.
