1.Error message on 'Levels' while trying to batch auto contrast

I am trying to create a batch process to take several hundred pictures and
run them through the auto contrast feature and save the processed pictures
to a different folder. I walked through the batch record process and after I
stopped the recording and tried to run it I got the following message:
Error: The command "Levels" is not currently available. (-25920)

This message was repeated for all 450 pictures with the name of the file on
the line above this message. Can some one tell me what to do to get this
batch processing working?

  Thanks

2.Auto Levels vs. Levels -- Histogram smoothness

If I take an image whose brightness range doesn't span black to white and
apply the Auto Levels command, I get a histogram that runs the entire range 
and is smooth, but if I do a supposedly identical thing with the Levels 
dialog box, I get a histogram that has many holes in it because the 
brightness levels are simply spread out and not interpolated.

Is there any way to get the smooth histogram effect while using the Levels 
Dialog so I can manipulate the mid-grey level independently of the black and 
white?

TIA

3.Stop auto TADOConnection from auto connect

At design time, programmers may set some TADOQuery to true to test
something, but it automatically turned the associate
TADOConnection.Connected  to 'TRUE', how can I stop it without manually set
it back to 'FALSE'?

4.scanning TEM (bw) negatives: auto contrast

Hello,

I am scanning TEM (transmission electron microscopy) negatives using PS

CS and Epson Perfection Photo 4990. In these negatives, there is a
small rectangular area on the bottom which has some information like
micron bar, etc. This area is in complete contrast with the remaining
part of the image. For a long time, I would scan negatives and
everytime it would give me different results (image contrast). I just
realized that it was doing so because it has some kind of auto
contrast, which would change the image depending upon the area I select

with the marquee during scanning. If I select only a part of the film
(without the transparent area in the bottom), it would give me results
as expected. I also noticed that if there is a feature in the
micrograph which has higher contrast, like a dark precipitate, it will
further increase the contrast. I just want my scanner software/PS to
scan as I shot the film, not to act smart on its own.

Is there a way to disable this auto contrast? I went into
configurations and tried a few things but could not fix the problem. It

is important for me to scan the whole film as it is, including the bar
in the bottom.

5.Batch Auto Contrast Question

I shoot about 300 photos on a day out and want to batch run them through
auto-contrast. Can you run the auto contrast or auto color correction on a
batch basis? I really need to be able to do this as doing it one at a time
is a real pain in the fingers.
   Thanks for any help on this
