elcome to a brand new place to get answers to the OS/2 questions that are nagging you! Each month we'll bring you tips, tricks, questions and answers from our readers and contributors relating to common (and some not so common) OS/2 problems and questions. If you've got a question or tip you would like to share with us, send it in and we'll make you famous!
Now, for this month's questions and tips...
- I only have one floppy disk drive, yet OS/2 puts a "Drive A" and a "Drive B" icon in my Drives folder. How can I get rid of the "Drive B" icon?
I know when I first started using OS/2 Warp at work, I was frustrated by the "B:" drive icon. I have two floppies at home (where I started with OS/2), so I had never encountered this before. Remembering that OS/2 is object oriented, and with a bit of research, I found an answer. These instructions are for OS/2 Warp, but the theory should be sound for OS/2 2.1+.
To get rid of the "B:" drive icon (remember, this just gets rid of the icon from the drives folder, if you have a "B:" drive, you'll still be able to access it via a command line):
With a problem so vague, there are a number of things that could be wrong but one thing to watch out for when getting errors related to SINGLEQ$ is possible conflicts between the video driver and parts of the system. As unlikely as it seems, try backing out to normal VGA and see if this clears up the problem. To do this:
My question is this: Is there any way to use JAOW to access Windows 95's long filenames when Warp is on its own HPFS partition?
The short answer is no. The utility in the JAOW package will create a LFN Extended Attribute for the VFAT filenames on your FAT partition. However, very few OS/2 programs can make use of these. The Workplace Shell and Stardock's Object Navigator are notable exceptions. However, unless you are content to only manipulate these files with the WPS, you gain no practical benefit from running the JAOW program (as the majority of OS/2 programs will have no idea how to use the LFN EA on the FAT drive).
One of the rumored features of the upcoming release of OS/2 (codename Merlin) is native support for VFAT LFN entries. We'll see...
My question is this. How can I rig up OS/2 to play a given track on my CD-ROM at a given time? I have figured out how to command OS/2 to launch an application (CDPM.EXE) at a certain time through Planner, but I don't know how I can tell my system to play a specific track (besides track one). I imagine this would be an elementary thing to do under REXX, but the on-line documentation doesn't help me out. Any ideas?
There is a PLAY.CMD REXX program that comes with MMOS2. Use this command line, assuming you have your CD hooked up as cdaudio01 (look in the "Parameters" box in the "Settings" notebook of the PM CD player program to be sure).
PLAY DEV=CDAUDIO01 TIMEFMT=MS FROM=800000 TO=1017000This example is for a time format in milliseconds (1000 ms per second) and is for track 4 on one of my CDs which begins at 13:20 (800,000 ms) and ends at 16:57 (1,017,000 ms). You must convert the times to milliseconds by multiplying seconds by 1000 and inserting the numbers as above. For more info on REXX see The REXX Cookbook (e-mail for more info).
