Re: i forget password to acces blockdiagram, how can i acces it?
You can't - that's the point of having a password protection. You could always try traditional crack3r methods, like a brute force script. See: http://digital.ni.com/public.nsf/websearch/BC99793C48857A41862565BC006F472C?OpenDocument
Re: Can I fit an equation to points entered on a front panel graph?
At least in LV 6.1, there's also a shipped example called Draw Graph.vi (search for 'graph' under Help-Find Examples)... but it seemed kinda non-intuitive and clunky. ~j5

Re: Use a . instead of a ,
From the LV 6.1 Help File: Front Panel Options Page Select Tools=BBOptions and select the Front Panel page from the pull-down menu. Use this page to set front panel options. Use localized decimal point=97Uses the decimal separator for the operating system instead of the period. Place a checkmark in this option if you want LabVIEW to operate within the system configuration. Remove the checkmark from this option if you want LabVIEW to use periods in all cases for the decimal point. Note Changes to this option take effect the next time you start LabVIEW.

Re: A confusing lev-mar error
The error refers to a syntax issue with the model description input. This input is a cluster of three strings: model, which is the actual equation (Ex: a+b*x+c*x^2); paramters, which are the solvable variables (a, b, c in the previous ex.) inputted as an array of strings; and the independent variable (x). All 3 parts of the model must match exactly (e.g. you can't have 3 variables in the model and 1 in the parameters, and if you designate x as the independent variable, there must be an x in the model equation). Additionally, the model equation follows standard LabVIEW formula node syntax, except there are no input variables designated (y=x+1 won't work but x+1 will) and you don't need a semi-colon terminator. Let me know how it goes, ~j5

Re: levenberg marquardt slower in LV7
It sounds like you have more than enough power: http://ni.com/labview/requirements.htm although it could be the OS... Did you just replace the top level L-M vi's or all of them? Like I said, the majority of the changes appeared to be buried in the lowest level subvis. You may want to try using the vi profiler to see where the majority of the time is being spent and isolate that vi. (Tools-advanced-Profile vis... at least in LV 6.1 I'm not at a station w/ LV7 presently). You'll want to select Timing details. See if any vi is running a long time or an excessive amount of calls and compare this vi to the LV6 version. If it's different, replace w/ the LV6 version. If it still slogs... h... maybe format and do a clean LV7 install? :) Lemme know what happens, since I use L-M frequently... just not in LV7 yet.
Re: levenberg marquardt slower in LV7
Ruud, I just ran the standard Parameter Fit LM.vi (search examples for levenberg) on both LV6.1 and 7 on the same computer (400 MHz AMD, 96 Mb RAM, Win XP Pro) with the default inputs, except I set the total pts to 2000. Both gave equivalent results in 24 s. Perhaps it's some other conflict on your setup or your modified vi. You may want to run the same experiment to see if it truly is the L-M routine or something else.
Re: levenberg marquardt slower in LV7
During the conversion, were the L-M vi's converted to LV7 or fully replaced? There appear to be a few changes between 6.1 7 LM vis... several of the lower level subvi's go changed to CIN's, vs pure LV. You may want to see if it's just LV 7 running slower (LV 7 uses more resources than 6 in general... I've got both on an old 400 MHz AMD w/ 96 Mb of RAM... 6.1 cruises... 7 is a drag). You might want to try using the LM vi's from 6.1 (do a save out w/ options to save all vi's), to see if it's LV7 itself or just the newer LM vis that's slogging it down.
Re: How AI Hardware Config.vi into AcquireProc N Scans - Trig.vi amplify gain?
If you aren't using virtual channels... Using the original AcquireProc example program, you can set the gain by putting values into the Input Limits. Labview will automatically scale the results. So if your signal is 0-10V, put 0 as the minimum limit, and 10 as the maximum limit. Typically, you''ll use the range of whatever signal you're measuring, but if a higher gain is needed, use a smaller range (liek 0-1V).

Re: justify indicator value to right
This was done in LV6.1, but it should be the same in LV7. Open a new vi and insert the default indicator. Right Click on it-Advanced-Customize Select the text and right justify it. Save it as a new control and close the custom control interface. On the front panel, right click to get the controls palette, selct User Controls (bottom right) and tack it down (pushpin). Hit Options (top right), edit pallete. Right click on User Controls window-Insert and choose your new indictor, with right justification. Save it out. Whenever you wnat it, there it is under User Controls.
