• trying to copy a file that had been opened on another computer and get "invalid MS-DOS function".

  With a flash drive, I took a document to another computer with a version of Excel, I had never seen.  I then brought the document to my own computer, opened it and was missing the lines and columns headers.  I also tried to copy the file to my CD - RW and the message "invalid MS-DOS function".

• Trying to create a bootable Windows 7 x 64 Flash drive. Get the "invalid MS-DOS function" error message when you try to copy the file 'bootsect.exe.mui' of the Windows ISO on Flash drive

  The title pretty much everything said.  I have an installer the ISO of Windows 7 Professional x 64.  I am trying to create a bootable flash drive using these instructions:

  http://www.OSNews.com/story/20795/Installing_Windows_7_on_the_Aspire_One_or_Any_Other_Netbook

  I followed all the steps in the guide without problem.  Windows Explorer shows the drive is NTFS.  I can copy all other files of ISO on the FlashDrive without problem.  Only, I can't copy this file.  I tried to copy it to my hard drive rather than on the flash drive, and it still does not work.

  I tried to create a file with the same name by using Notepad to see if there was a problem with the file name.  I can copy this file on my hard drive flash drive, but I can't always copy the ISO file.

  I am running Windows 7 Home Premium x 64 edition and using a Corsair Flash Voyager 16 GB flash drive.

  I have recently installed Windows 10 free update.  Now I am unable to delete .pdf files and get the invalid error message "Function MS-DOS."  It has never been a problem with the previous Windows 8.1.  I contacted Microsoft technical support and they told me there is a problem with the .pdf application and I need to contact Adobe Acrobat. This can be corrected?

  uninstall any version of acrobat is installed.

  Restart your computer.

  delete all to delete pdf files.

  If this fails, it is a problem of ms.  If this attempt is successful, then reinstall your acrobat.

• Invalid line in functional reference Global

  I must forget something very basic about queue references. Here's my problem... I have a LabVIEW application that generates dynamically from the Q (a queue is generated in order to act as a stream dedicated to each chart created). Queue references are created and stored by a functional overall (FG - Manager.vi queue). This functional global is called the "Launcher" and the "Monitor". Everything works fine until the pitcher is closed how the queue references show "invalid Refnum". The reference is always in memory because the functional overall is still called by the monitor memory then why are my Q turning references invalid? See example attached LV2010sp1.

• Sound/display issue for Y560

  I called Lenovo support yesterday for help with a problem of great keyboard I had, and as part of technology works on my computer, it is obviously invalid of any function it is which shows that physical volume control reacting to the screen.

  Previously, I'd get a popup notification if the mute button has been enabled or disabled and a Visual of a control volume, moving upwards or downwards. Part of the issue of the keyboard is that the characters randomly activate the volume, it is REALLY important that I can see if it is triggered, I use this laptop in class.

  So, any ideas? The problem with keyboard is something that they are working on, but I'd really like my volume controls to be visible on the screen at that time. I don't talk to the traditional volume control, but popups that show when something is turned upwards or downwards.

  Thank you!

  The screen display is a part of the suite software Lenovo Energy Management. Re-install, and you'll be all good!

• Build the path for a reason any not giving "a path".

  So I have a path that leads to a directory that is already created and a string constant and combine them with the build path function VI to return a full path, to move to some write to file function. It works very well, as seen in the half top of diagram this picture (with test.txt) block:

  

  But I want to make each file named after the date and time, as you can see I did in the bottom half of the diagram above black. You can see that the file name it produces looks pretty simple for me.

  Now, I try to connect the output from the bottom to the top, instead of test.txt:

  

  And now instead of writing to the file, it appears with a dialog window asking the name of the file to use for me. I have reviewed the documentation for function that I convey my path of the file (write on the file of spreadsheet VI), and he says:

  file path is the path name of the file. If file path is empty (default) or is , the VI displays a dialog box from which you can select a file. Error 43 occurs if you cancel the dialog box.
  

  Well, this is probably what is happening here, I guess. But why build it a path function, is not a way back?

  If you go to the manual to build a path, it is said:

  name or relative path is the new path component appended to base path. If name or relative path is an empty string or an invalid path, this function sets appended path to . If base path is an empty path then name or relative path must be an absolute path. This function then sets appended path to the absolute path in name or relative path.
  

  Yet, he does not say is what a path not valid. I can't imagine why it is not, as that looks really useful for a manual to have, but good information. Googling "labview build an invalid path" returns first page manual that I've just referenced and then this page, but everything seems about invalid paths is that they can't have slashes, which is not my example.

  I apologize if I am missing something obvious, but it is anywhere, or you're just supposed to guess? I guess it's possible that it is more generally known of Labview that I'll go with more experience, but it still seems that would not hurt to have right on the page. I tried a few obvious things such as the removal of spaces of my date, but no luck.

  Thank you!

  A file name cannot contain colon ': '.

  For example, use windows Explorer and try to change a file name by inserting a ': ', this is what you would see.
