Help !!! Up down left right slides missing from block diagram !!!

[New2Labview]

 H E L P !!!!  Hi I am right in the middle of editing my labview program and all of a sudden on my block diagram the up down and left right slides have dissappeared from the screen ? How do I get them back ?  I have tried closing the program and reopening it but when the saved program reopens  the slides are still missing for pulling the programs scope left right up and down !!! Thanks John

Does this happen with other VIs too? If so, let LabView create a new labview.ini. For this, you close LV, browse to the LV- Program- folder and rename the "labview.ini". On the next startup, LV creates a new one with default settings. Perhaps this helps.
If it is the only VI without scrollbars, this VI seems to be corrupted. Perhaps it helps to select the entire block diagram and copy it to a new created VI (with scrollbars). Try to do it via the clipboard (Ctrl+C Ctrl+V) or with drag&drop.
Hope this helps,
Dave

Hi,

are you sure the slides (please fill me in what are those?) are missing?
May be you have dragged the mouse while holding down the CTRL-key that auto-expands your block diagram?
To verify use the find function and search for the name of an indicator/control that has gone missing
Another way might be using ctrl-shift-N, this will show a small overview of your VI.

BTW your VI should fit into one (1) or two (2) screen of 1024X768 and never expand it in both directions!!

Have you tried to resize your panel?  I have seen this behavior in isolated instances (irreproducible, of course ) and resizing the window usually cured it.  Please post your VI, if you can.

 Ok I have tried everything everybody advised here. Thank you for the help to all.  I have also noticed that if you resize the window to 1/2 screen height  the up down left right slides come back.  Nothing has worked. It has to be corrupted 😞 .......if anybody has any more ideas please let me know. Smelling a resource size error I moved the vi to a machine with 2x the memory of  the initial Labview machine ...it still made no difference....I think I am going to have to start over 😞 .....JFK

Good morning John,
        Please post your VI so I can try it on my machine.  When you open an new or example VI, do the scroll bars work correctly?  Is it oossible for you to do an Edit>>Select All to get all of your block diagram, so you can transfer it to a new VI?  What happened when you tried the Ctrl-Shift-N that TonP suggested?

Thanks,

NathanT

Try a "ctrl-t".

 Thanks Ben ....cntrl T  tiled the program left right but the slides are still missing ......heres the wierd thing If I crunch the vertical height by 50% dragging the top edge down ....the slides mysteriously come back ?????????  but the data starts to get corrupted in the 50% window as you move the slides up and down ..if you then do a save  insane objects are created and the program is trashed from that point on. This has happened on 2 programs at that 90mb point...before that everythings cool but labview has problems apparently around that 90mb  size.

I suggest you contact NI Support (800) 433-3488 and send your VI to them to investigate.

You may have found an upper limit that has never been tested previously ( I developed applications with 1000+ VI's but never a single VI that used 90 Mb, my largest was probably 60 Mb but that was due to the default data in a 3-d graph).
