File Path Control question

Simple question: How do I invoke the Open command in the File Path control? My reason is of my user hasn't supplied a file, then I want to force the user to select one.

Most file related vi should prompt if there is no file path. If for some reason you are not getting that you could check to see if the file path is empty and add a prompt see below:

How to force the File Path Control Browser button to the RT Target instead of the host machine?

I am building an application on a RT PXI system, and for one of the functions I would like the user to be able to use the browser button of the File Path Control to choose a directory on the PXI. However the browser button seems to only want open a file on the host PC, even though the application is fully deployed on the target. Note that I am controlling the PXI from a host PC.
If anyone has any suggestions that would be great. Thanks.

Hi,
Unfortunately, there is not a VI to do this. Are you browsing to these files from your host VI? In order to access the files on your PXI RT target, you'll need to FTP in and browse to them that way. You could programmatically do this, but there is not a simple VI to do so.

File path control - browse button colour/color

I can't change the colour of the browse button on a file path control. I'm using LV 8.5, but I think I have the same problem on 7.1
Is the only way to change the colour to customise the control? Every other part of it seems to take colours from the tools palette.
Thanks for any pearls of wisdom.
Jon.

I am able to change the path browse button color in 8.51 are you trying to change the button color or the color of the folder on the button. To change the buttoin color use the paint tool and make sure you hit the space bar so you are painting the left color (Background color I cant remember which is which). This probably doesnt work on system buttons.

"File Path Control" default Value

Hi - How do we set or change the default value for "File Path Control" (Control --> String & Path ---> File Path Control)?
I typed the default path into the control field on the front pannel and save the VI file. The value gone when I reopen the file.

[...] difference between Not a path and Empty path... Why?
Not a Path is a specific value for the path (<Not a Path>).
Developers should use this to prevent situations in applications, where a user has to select a path before performing an action (e.g. saving a file). If the user skips the path selection, the application still has "Not a Path" and can prevent errors and tell the user to select the path (error handling!).

File path control-how to avoid the user to change the path string

Hi all,
I'm using "File path control" to chose file name. I don't want the user to write the path in the control directly (by typing) but only to choose the file via the button on the right.
I can implement this behaviour with path indicator and button of course. But I belieave that it can be done more elegant - only disable the part with the string - not the whole "File path control". But how? I tried to customize the control but not success.
Is it possible?

The way I've done it is to make the path part of the control tiny and hide it behind a string indicator. Then whenever the path control changes value (by pressing the Browse button), I populate the string indicator with the path value. Here's a sample VI demonstrating this method, saved in LabVIEW 8.0.
Hope this helps,

File path control: invoke file browser activation

Hi there,
on the front panel of a vi I want a file path control to open automatically the file browser window when the user clicks into the path control. Is there any way to do that programmatically after the mouse down event has been fired? I couldn't find a suitable method so far.
Thanks for any hint,
Peter

I should point out that the mechanism you (I am referring to the OP) are proposing is counter-intuitive. Web browsers have started to do this, but they do it claiming security issues. Frankly, I think the security concern is small compared to the annoying change in normal behavior, but that's my just my opinion - I can't change the way Firefox or IE works.
Do you not have the Browse button visible for the control? Clicking this displays a file browser. This is normal and expected behavior.

Massive mp3 file(path) move question

Alright so I recently purchased a 2 terabyte network server for my home network. The purpose of this is to move all my music, movies, photos, etc. to the network drive in order to clear out all that space on my laptop's drive. At this point and time, I've only copied all my music to network drive. Figure the next step would be is to delete all my music off my local drive. But then got a little worried about iTunes. Now when I delete my music off my local drive, iTunes will be looking for the mp3s via the originated file path. Obviously the file is not going to be there. So when this happens in iTunes, the circularly enclosed exclamation point pops up and iTunes wants you to manually and find the file for it to play. So essentially my question is... Since I'm doing this on a large scale, Is there an easier way to get this done?
Best solution I was able to come up with was to delete all the songs in iTunes and re-drag all the music back in there. BUT... the problem I have with that a good majority of the music's album artwork were manually put in by me (kind of uh...yeah about seeing the album artwork on the screen when I'm listening to my iPod). So I don't want lose all that it. Help! Kind of long, I know. Appreciate any help or suggestions.

Database Toolkit Sub query Syntax and file path expectation question.

I need some assistance from those of you smarter than I.
I have two database files (not two tables in the same database file) one represents information delivered from an external interface, and the other is used by the internal interface associated with the processing half of my application. Data is received (i.e. fields are populated) from the external interface to one database file and that data is then copied to another database file where the information will be processed by the internal interface. This is being done because I am worried about file access issues that might occur if two different interfaces (external & internal) try to access the same file at the same time (without dealing with semaphores). I am not too worried about the sanctity of the data since each record supplied from the external interface should not effect any of the data being used by the internal interface. So the first question is , am I being to primitive in my thinking assuming that I would run into file access issues if I were to just use two tables in the same database file for the same purpose ?
My second question is related to my current implementation where I have two separate database files representing the external and internal interface data. Currently when a new set of data is entered into the External Interface Database file, an alert is issued, and another task copies the data from that file into Internal Interface Database, then the data is deleted from the External Interface Database file. My question is related to the syntax that I am using to provide the described functionality. I am currently using a INSERT with a subquery to the External Interface Database file i.e. INSERT INTO InternalDB FROM ExternalDB.ExternalTable WHERE Order = '06306049'; .
My question is when I run this query with both database files in same directory I get an error stating that the ODBC driver can not find the ExternalDB.ExternalTable in the Parent Directory of the subdirectory where the files are actually located. The system DSN is set up correctly for the ExternalDB, and if I move it to the parent directory the query works correctly, my question is why would I have to put the two database files in seperate directories for this to work and is there a way to avoid this ?
Thanks..

Selecting Multiple File Types With Path Control

My application uses a file path control for the user to specify an output file. This output file can have two different formats (.csv or .mbf) which is unknown until the user specifies it through the file dialogue. However, when the user inputs a file name with a .mbf extension (test.mbf, for example), the file path control automatically appends the typed-in name with a .csv extension (test.mbf.csv). Given that the Pattern field on the control is written like this: *.csv; *.mbf., it seems that the control is simply taking the first file pattern listed and appending it to whatever is typed into the File Name field in the file dialogue box. Selection Mode is set to "Files" and "New or existing".
Anyone know a way to smarten up the file control to recognize the appropriate file type?
Using LabVIEW 8.6.1.
Thanks!

Instead of using the file path control, try using the Fial Dialog Express VI. This will bring up the same dialog box but will allow you much more flexibility. Replace your file path control with a button ("Specify Path" in my example code):

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 play SWF with AxShockwaveFlash control using a stream rather than a file path?

My WinForm app downloads and plays SWF files from my server. Currently, I have an object of type AxShockwaveFlash called "flash" display the movie. The code I use to load the SWF is:
flash.Movie = "http://example.com/file.swf"
The URL is generated dynamically by the module based on what the user wants to watch. I'd like to know how can I load the SWF using a memory stream rather than a file path? I have already configured my server to process the url and return the contents
of the file. What I don't know is how to read those contents within my WinForm application as a stream instead of the default which is to just provide a URL path to the movie.
For instance I think I can use the Net.HttpWebRequest object to make an HTTP request, and read the response contained in the resulting Net.HttpWebResponse into a stream, but I have no idea what I could do to that stream to feed it to AxShockwaveFlash
A very similar question was posed on
stackOverflow but I cannot make sense of the answer (I'm quite inexperienced).
I'd appreciate your help,

A basic questions on file paths

hi everyone, just trying to get back into the revamping our workplace website, stripping out the old flash based site and implementing a nice smooth css controlled site.
i've gone through the creating your first website tutorial by David Prowse and found it to be very informative but still leaves me with a number of questions. Is there an actual thread present to ask questions based on the materials presented in the 6part tutorials?
a simple question on file paths:
is. <link href="./styles/main.css" the same as
    <link href="styles/main.css" ?
which one is better (foolproof) for uploading to a webspace and which format should be used for all filepath declarations (css, js, scripts etc)?
Btw, what is the difference between
styles/main.css
/styles/main.css
./styles/main.css
../styles/main.css ?
thanks for any help

Let me be the first to start here:
1)
is. <link href="./styles/main.css" the same as
    <link href="styles/main.css" ?
No it is not the same. The first goes to the root folder and looks for styles folder and then main.css file; The second simply looks for the styles folder in the same folder as the html page in which this is defined. so this is at the same level as the document.
Which one is better? It depends on your site definition and the best thing is to let DW decide how to link the file. Dw is pretty good at getting things right such as this one.
Is there an actual thread present to ask questions based on the materials presented in the 6part tutorials?
I thought David's articles had a space below it to make comments and/or ask questions but I have not been spending time on DW forums recently because I have noticed that most answers here have duplicates or triplicates for most questions stating more or less the same thing so there isn't anything new here.
I think I have covered almost everything asked in your question.
Hope this help.

Problem with the log file path on the Data Logging Control Veristand

Hello everyone,
My problem is that I use a computer as a gateway on the network. It is connected to PXI in Real Time. I have another computer connected to the gateway to read the given PXI. I am unable to record on my local hard drive using the Data Logging Control VeriStand on the second computer. However, it can save me on the hard disk on the network. Moreover, I have no problem to record if the computer is a gateway.
Regards,
Kamal Bouamran

For simplicity, let's call the computer running Veristand Computer A and the gateway computer Computer B.
So, just to clarify, you're running the Veristand workspace on Computer A, which is connected to your network and the RT PXI (on which the system definition file is deployed) through a gateway, Computer B. With this setup, you can't use a data logging control to save a file to Computer A's hard drive. However, you are (from the workspace running on Computer A) able to save a file to Computer B's disk or to another drive elsewhere on your network. Is that all correct?
What happens when you try to configure the control to log to computer A's disk? Do you get an error (and if so, what error)? Does the file path default to a different location?
Also, what version of Veristand are you using? What version of Windows are you PCs running?
Regards,

Question re: moving iTunes library to new computer where files have different file path?

Hi everyone-
I just got a new laptop and need to transfer my iTunes library to the new computer.
On my old computer, the hard drive was partitioned into a "C" drive and an "F" drive. The new laptop is just "C."
Since my iTunes library was on the "F" partition on the old laptop, the file path for all the files is going to change when I transfer to the new laptop.
I can find dozens and dozens of articles online about how to move iTunes to a new computer, but none of them seem to address the file path issue.
Does anyone know where I can find detailed instructions on how to make this work?
Thanks in advance.

Quit iTunes.
Move the entire /Music/iTunes/ folder to the F: drive.
Hold Shift & launch iTunes.
Select Choose library... and select the iTunes folder you moved to the F: drive.
Everything should still work fine.
Now go to iTunes prefs > Advanced.
Set the iTunes media folder location to the iTunes folder you just moved to the F: drive.
iTunes menu File > Library > Consolidate library.
This will copy all your media into the iTunes folder (F:\iTunes\iTunes media\ folder)
Let it finsh.
Quit iTunes.
Then you can copy the F:\iTunes\ folder to the new computer.
If you copy it to /Music/ folder, just start iTunes and it'll work.
If you copy it elswhere (such as another drive) hold Shift, launch iTunes, select Choose library... and select the iTunes folder.
