  How to test if a path to a directory instead of a file?

  File (path) .exists () new seems to return true in both cases.

  I found myself new file (path) .length =-1, because the directories seem to have a length of-1 as reported by the InDesign scripting DOM but I don't have really a lot of confidence that it is either portable or reliable in the future. Is there a better way?

  I guess I could try to create a file in the directory, but I don't like not to change the file system, and the script may not have permission to do so anyway. It's JavaScript, so it's hard to pay for a program (like ls - l) external, and that would really kludgey anyway.

  The slashes do not affect the. exists().

  the file manufacturer allegedly returns a Folder object in this case, but. constructor.name is always file.

  What is recommended? Thank you!

  If I understand the question, initially, all we have is a path string, and the decision is to know if create a file or folder from that object. Of course, then compares instanceof or constructor.name is questionable.

  A similar length is-1 observation would be the property of File.type, which is not defined for the records.

  Have a look in the JavaScript Tools Guide gives the best approach, though.

  "If the path refers to an existing folder:

  The file function returns a folder instead of a file object object.

  The new operator returns an object of a non-existent file with the same name file. »

  So - simply omit the 'new' and the types of tests, such as discussed.

• How to test for the node XML empty?

  If (selectedImage.detail! = "")
  
  works with
  < picture detail = "" >

  but not

  < / image >
  
  
  Hope that makes sense for a person, can't think really how to explain it better, I'm sure it's a fairly simple thing

  I did not understand. You try to search the nodes in detail where the text node is empty?

  Yes - for that I can't ignore explicitly their.

  Seems that all I had to do was if(!selectedImage.detail)

  Thanks for the reply - despite my not knowing how to phrase the question.

• How to test moduleDeletionsPending, in the Simulator, I don't have the option to remove my application

  How to test the following?

  I want to test the functionality by using the method public void moduleDeletionsPending (String [] moduleNames). I had written logic that removes files from an SD card and it works when I call a menu inside my application item.

  However, it should only be run when I uninstall the application.

  In 9700 Simulator, if I select Options > Applications > [highlight the application] > [open the menu by pressing the Insert key on my keyboard] - I don't see the option to remove the application.

  I don't see the delete option for other applications, such as the Klondike card game.

  Should I set a property or the permissions of my app should be deleted in a simulator, so I can test the moduleDeletionsPending method?

  Thank you.

  You will need to 'install' the app in the BlackBerry smartphone Simulator so that your application appear in the list of applications.  You won't see here when you perform an execution/debug as, when you use the file, the option of loading or copy it into the directory of Simulator.

• How to check all existence directory in TestStand?

  How to check all existence directory in TestStand?

  Is there a function TestStand? Or another option without writing my own code in the external program (for example, LabVIEW or C)?

  Thanks in advance

  Try the Engine.FindPath method. BTW several times when you do file IO, depending on what you're doing exactly, you need to write a code module.

• "NaN" - how to test in VBAI <>- BT?

  I use VBAI to measure the length of a line.

  I use LabVIEW as the custom interface.

  In VBAI, I use "Update of Inspection" to send the data of length to LV

  How can I check in vi, that this figure is "NaN? This will happen when the line is not found.

  I tried to use ' NaN/path/RefNum"of the LV, but it simply doesn't.

  Help please...

  I don't know how you test this. I tried it and it works fine. Make sure the update of Inspection stage has the flag to 'Run the VI after update of the indicators'.

  If she still doesn't for you, let me know and I can send you a simple example (if you need an example, let me know what version of the VBAI you are using).

  Thank you

  Hey,.

  I was checking for error 66, I think that it check if the connection has been closed in order to reconnect

  do you not think that the error 56 or 60 are better?

  with respect,

  56 is the time-out. This will depend on your remote service if this should be considered as error or ignored. If it is a server application, it should certainly be able to respond within the time limit. But if your host application is the server and the remote application is the client it is very common to receive a time-out error when querying the client if it has new data to send.

  Order the examples mentioned previously, they really give you a good idea on how TCP/IP network communication must all work, even if there is still a lot to improve to create a truly reliable connection. But start from there come back if you get into trouble.
