Get the properties of a large TDMS file is very slow

I have a very large file PDM with about 3000 properties. After that I open the file, it will take about 2 sec to read a property with the PDM get properties VI. I'm reading all the properties, so I can do some calculations on them. It takes too long to read them all. Y at - it a faster way to read. I think now I should have stored the values in a channel, but it does not help my situation.

George

Thank you for your answer, George!

Then, I'm afraid that there is no simple workaround solution unfortunately. If possible, you may want to consider splitting the TDMS file to some smaller TDMS files. We had similar bugs report, on the performance of the PDM get properties, especially when having a large number of properties PDM, we worked on possible optimization now.

  • Why do I get the message "cannot write in print file specified"?

    When I print from Framemaker 8 using the Adobe PDF printer driver, I get the message "Cannot write in print file specified."  And I am not able to generate ps file.  Why is this?  What could be the problem?

    I am able to print to another printer - for color printer driver - of my office with no problems.  So I guess that I don't need the Adobe PDF printer driver, but it's an others on my team use documentation - I was wondering why it is not working for me now (even if it is used for).

    FM is not a true PDF Export. There is not a "SaveAsPDF", that comes silently prints (background task) a temp ps of the file using the AdobePDF printer instance, called Distiller with a specified joboptions file and deletes so the temp folder afterwards.

    AdobePDF print through the PDF port, which is actually the same as the SaveAsPDF FM approach.

    @Wish, have you checked that your AdobePDF printer instance pointing to the 'Adobe PDF' port (printer properties > Ports)? Alternatively, you can try setting the AdobePDF in the FILE: port.

    Also check that you have permissions to write system level to where you try to put the temp FM ps file.

    Hello

    What a click right on? Usually, you should be able to see the Page properties when you right click on the map view of a page, or you can also find properties page if you open the individual pages and then go to the Page-> Page Properties. However, if you are in map mode and you try to use the Page-> Page Properties, this does not work and the "Page Properties" option may be dimmed.

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.
