HI

i m getting an error message "Insane Object at FPHP+34 "PostProcessing_AllChannels.vi":{tdo}{0x800}:FrontPanelDataController (DCO)" in LV8.0 after converting one of the vi's from LV8.6 to LV8.0 . i have no clue about this error message . Can somebody guide me with this?

yep ur right ... i got it working ..... the duration is now max- start and it works fine for me

thanks a lot for the support guys ... i appreciate it. :-)

i have got the subset starting from the point i require but not to the point have specified i.e. XscaleRange.Max .... it gives excess values of the waveform which is not required.

in the vi which i have attached i have 3 waveform graphs ... One has the original waveform, the second is where i zoom the waveform and after pressing OK the zoomed part of the waveform is displayed in the 3rd graph.

what am i doing wrong??

this is the block diagram

SAMplezoomData.vi

HI,

I have been trying to take the array subset of a waveform after zooming the waveform using labview zoom in the waveform graph. initially i bundled the y-array, sample time and start point into cluster and displayed it in the waveform graph. using two cursors i select range to be zoomed ....after zooming i need to acquire the zoomed part of the waveform from the graph ...

can anybody help me out with this?

That is still slow. What SQL statement are you using? Also, have you indexed your table?

I just did a simple test with: SELECT * FROM `databasename`.`tablename` of 1000 records and it takes: 15ms.

Using the changes mentioned and with the original code when i query for 632 columns i get 4000 rows in about 2-3 mins ....y is that so?? is it bcoz of the number of columns ??
