How do I reference "ok" button in file path?

Here's a quick question, I am using the LabVIEW file path control icon, when you hit the little file browser up pops the window where one can browse and select a file. Once they are happy they can hit the OK button. I am trying to embed this as a part of another program which I want to wait until the OK button is pressed. Where is the property node for the "OK" button? I can't seem to find it.

I want to wait in the program I am running. The real issue is I have the individual instance of this VI working great, however when I go to run it as a subVI embedded in a higher level program, if the path control is empty or has the wrong value the progam is not giving the operator the time to change it. Thus it would be very nice if some how I could use the operator acknowledging the correct path as a precursor to continuing with the program. I must admit I have very little experience programming in LabVIEW.
You can check the validity of the path, and if it is not suitable, call a file dialog function. Check the new path and also if the dialog go canceled and proceed as needed (ignore error, ask again, etc.)
Expection handling and such really needs to be done in code and LabVIEW has a rich selection of options. Is the path received from a connector to the subVI? Under what conditions is it empty?
I agree. I also feel it is far better to prevent the user from doing something wrong than it is to let them do it and then try to recover from it. For instance, I'd keep the "OK" button grayed out until a valid path was entered. That way you avoid having to recover from "bad path was chosen after pressing 'OK'."

How to get the loaded client sequence file path/name?

I added a step in Process model, and wanted to get currently loaded client sequence file name/path. I used the variable of "SequenceFile.Path" but then I realized what I would get is the process model file path, not loaded client sequence file path/name. How can I get loaded client sequence file path/name?
Thanks!
Jacky

I dont understand what you are trying to achieve. Can you provide more information.
If you are trying to dynamically load and run a client sequence file at run time you need to make a couple of calls to the TS API from inside the process model, Engine.GetSequenceFileEx to get a reference to your sequence identified by its pathname, and then Execution.ClientFile to tell the process model which sequence you want to run.

How can I make Spotlight show the file path

How can I make Spotlight show the file path in the Spotlight menu for selected file?

Via Finder certainly, but not in the menu. You can view the file path in the Spotlight search results display by pressing the ⌘ key (while hovering over a file in the results), though. The path will display at the bottom of the Quick Look output, or cycle through that location.

How to reference Macintosh HD in file path

How do I reference the Macintosh HD in a file path, in case it is renamed?
I tried:
myFile = File ('Macintosh HD/myTxt.txt');
But nothing happens, when I write to the file.

Jong, I tried that script on a mac with a single partitioned drive (one side as boot) with about a half dozen external drives/servers mounted. Every other drives mount point should be in '/Volumes/' as suggested… Im at home now on my little iMac this is what I see if I put USB's of the same name in… then go check in terminal…

How to handle the 'folder button' in the path command throug Event loop ?

Hi everybody.
Again a stupid question but I can't find the answer.
My VI has a dynamic event loop, to execute the right code depending on user action.
Everything is working well but now I wish to do the following :
I use a 'path command' with the path entry (like for text) and the folder button.
the user click on the path entry -> something A happens.
the user click on the folder button -> something B happens.
As the folder button and the path entry are the same command, how to differenciate those two events in the event structure ?
Maybe there is a value in the node, but I can't find it ...
Thanks for helping !

You can't do exactly what you are wanting to do. The problem is that you can't trigger an action based on clicking the browse button. To implement that you will need to hide the browse button that LV creates and put down a button of your own that you can then track and respond to independently.

How to validate a Particular Directory or file path in Presentation server.

Hi SAP gurus,
I am having a requirement where I want to download a file into the Presentation server.
The file path to download will be provided in a parameter.
What I want to do is to throw a message to the user if He/She provides a wrong Directory or File path.
For example :
Say the user is providing the file download path as " E:\test.txt", but there is no "E" drive or such directory in the presentation. So in this case I should be able to check the wrong Directory provided by the user and throw some message to the user saying there is no such Directory present. Please give a proper directory or similar messages.
I have found a FM: PFL_CHECK_DIRECTORY but i am not able to use it properly.
So do you have any FM or any method and its explanation to fulfill my requirement .

Do it this way:
tables:
spfli.
parameters:
p_file type rlgrap-filename          " File name
                   obligatory.
Data:
t_final_data like table of spfli.
at selection-screen on value-request for p_file.
call function 'F4_FILENAME'
   exporting
     program_name        = syst-cprog
     dynpro_number       = syst-dynnr
     field_name          = ' '
   importing
     file_name           = p_file.
at selection-screen.
data:
    lw_file type string.              " File Path
lw_file = p_file.
select * from spfli into table t_final_data.
CALL FUNCTION 'GUI_DOWNLOAD'
   EXPORTING
     filename                        = lw_file
   tables
     data_tab                        = t_final_data.
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
if sy-subrc <> 0.
    message 'File not found' type 'E'.
endif.
With luck,

How can I reference an external help file from context sensitive help at the control level?

My goal is to provide context sensitive help for each control displayed on the front panel using a help file created externally. I know that at the VI level I can specify a Help Path; I want the same behaviour for each control inside a VI. I also know about creating a custom control and specifying the Help Path in there, but it doesn't help in this situation, for I have hundreds of controls in my application and I cannot go back and replace each one with a unique .ctl. If I could override each instance of the custom control with unique path data that would do the trick, but that's not how it works.
Is there a way to add the Help Path information to regualr controls?

This functionality is not yet built into LabVIEW.
About all you can do is cut and paste the help for each control into the description for the control. It is tedius but a finite task.

How to use Client_Host without the exe file path

Hi,
i'm using oracle forms 10g,
in my application the users can upload any type of files (doc,xls,pdf,avi ,.. etc) and any user can download and open any of these files.
i implement this using client_host and including the path of winword.exe or AcroRd32.exe ,...
in many cases i don't know where these exe files are installed in the client side or whether it is installed or not.
i tried this command : client_host('calc.exe') it works and show me the calc without including the path of this exe file.
what i want to do is to just call the target file(doc,pdf,avi,..) in the client_host without having to precede this with the exe and path like the calc.exe example.
if you go to start->run and write for example c:\ahmed.mpeg , windows automatically call the real player or any other video software installed and open the movie.
can we implement this in oracle forms? and how?

How do I hide a document's file path in the book panel?

For reasons I don't understand, FM sometimes displays the complete filepath to a document or book, and sometimes it doesn't. How can I keep FM from displaying it?
Cheers,
JP

Hi Anjaneai,
Thanks very much for this answer. It doesn't really solve my problem but it made me realize I have a much bigger problem to deal with. To make a long story short, I've been working with the book and document files that are stored in an old directory, which I did not expect. I simply want to move the book file and document files to the same new directory, and have FM handle these files and no others.
I thought I had already done that, in this way:
I moved the all the files into the new directory via drag-and drop (in Explorer). I then double-clicked on the book file in the new directory. I opened the chapter, IX, and TOC files by double-clicking on them in the FM book window.
I then did a "Save Book." I assumed that saving the book file would save it, and all document files in that new directory. (Remember, all the files had already been moved to the new directory, and I explicitly chose the book file from that directory.)
So all my files are up-to-date -- they're just in the wrong place except for the book file itself.
How can I get them to the right place?
I can't move the chapter files to the new directory "manualIy" and expect FM to find the right ones automatically when you open the book file.
I can't do an FM "Save as" for .fm files because the Files menu doesn't offer that option for files.
I can't move the files to the new directory and open them explicitly via double-click because when I do this, FM still fetches the files from the old directory!
Best,
JP

How can I get currently running script file path in PS CS (8.x)

Is it possible to retrieve full file name of my script file in Photoshop CS (8.x)?
Constructions:
b ScriptName = $.fileName
and

are not works in Photoshop CS

Hi Mike,
Based on your description, we can enable the policy setting to see if it helps:
Computer Configuration\Administrative Templates\System\Logon\Always wait for the network at computer startup and logon
Besides, regarding how to assign log on scripts, the following article can be referred to for more information.
Assign User Logon Scripts

Moreover, as Carl suggested, instead of using scripts, we can utilize Group Policy Preferences Dive Maps extension to map drives for users.

How can I reference more than one jar file

hi, In an applet, I use
Archive = "foo.jar" to reference this jar file.
But how can I reference more than one file?
Thanks.

Suggestion: spend a few minutes reading the tutorials.
http://java.sun.com/docs/books/tutorial/applet/appletsonly/html.html
You can specify multiple archive files by separating them with commas:
<APPLET CODE="myapplet.class" ARCHIVE="file1, file2" WIDTH=anInt HEIGHT=anInt>

You could use a loop and an event structure and place the file operations inside an event case that is triggered by a value change of the path control.
