"File dialog" to Frontmost position

Guys,
When I open file dialog, the file dialog window is always behind the front panel.
See attached files.
When I run Main.vi, it will open Sub.vi.
Here, window behavior of Sub.vi is floating.
If I click the button "open file dialog", the file dialog is behind the Sub.vi.
How can I bring the file dialog to frontmost.
Thanks.

Thanks smercurio_fc
Yes, it works. It is strange.
When I tested it (with changing window behavior), it didn't work.
The file dialog was always behind sub.vi.
hmm...
I want to pop up sub.vi when Main.vi runs, that is reason I dynamically loading VI
And I have to transfer data to Sub.vi, that is reason I call it in the while loop.
I'm, actually, not very good at LabVIEW, Would you suggest me more smart method?
Thanks a lot.

File Dialog Box Position

Hi there,
I've been unable to find anyone else mention this problem, but then again, I'm not exactly what to search for.
Since installing Lion, I've had a problem where when I try to open the file dialog box to save or open a file, it's position is always further down. This is annoying, especially for programs that open files from my Download folder, which is continuinally growing as I add more stuff. The sort on this is by date, and so usually I want to open the most recently downloaded file, which I have to scroll further and further up each time.
Is there any way I can get it to jump to the top?
See the attached image to see what I mean exactly.
Thanks!

the length of the session is not the problem. it is set to 50bpm at 29.97 drop frame which gives me 2138 bars at 3 hours 51 minutes record time. I only used 1896 bars at 2.5 hours to record the program and there were only 5 tracks recorded. the problem starts when I try to bounce the session to an interleaved stereo file either online or offline. a dialog window says it will exceed 2gigs and prevents me from performing the bounce. only when I select split stereo instead of interleaved within the bounce window does it let me bounce. I think it is because the 2 resulting mono files(left and right)are each less than 2gigs. Is there a limit to the file size you can create when bouncing?
a 2gig file sounds small to me when there are video files much larger within video editing software.

LV 6i / File Dialog Positioning

Hi all,
when I run the file dialog in 6i, it seems to default its position (the pop-ups left/top corner) to the left side and below the title bar of the calling vi's front panel. I'm running on win 2000
Is this normal behavior? Can I alter this somehow?
TIA
Denis Jolivet
[See first answer for additional information]

Not really sure but that sounds about right.
You can edit the window options of the pop-up and tell it to
go to the center of screen. It will be dead center of the screen
reguardless of the position of the calling VI.
You can also use the VI server and place it whereever you want.
(At least this is what I remember from ver 5.x)

How to prompt user to select multiple files in file dialog using scripts

Hi, is there a way to allow user to select multiple files inside the file dialog using scripts? So not just something like "*.ai" or "*.eps" but where the user can actually use their shift key to select a batch of files inside the file dialog and then the script would process each one.
Thanks!

// Main Code [Execution of script begins here]
here's what I have so far. it would also be nice to not have illustrator stop at errors.. right now, it skips dialogs but on errors, it still stops.
// uncomment to suppress Illustrator warning dialogs
app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS;
var destFolder, sourceFolder, files, fileType, sourceDoc, targetFile, pdfSaveOpts, folderName;
var fullPath = "";
var finalSlash;
// Select the source folder.
sourceFolder = Folder.selectDialog( 'Select the folder with Illustrator .ai files you want to convert to PDF');
f = find_files(sourceFolder);
function find_files (dir)
    return find_files_sub (dir, []);
function find_files_sub (dir, array)
    var f = Folder (dir).getFiles ("*.*");
    for (var i = 0; i < f.length; i++)
        if (f[i] instanceof Folder)
            find_files_sub (f[i], array);
        else
            if (f[i].name.slice (-3).toLowerCase() == ".ai"          || f[i].name.slice (-4).toLowerCase() == ".eps")
                    //convert the array-listing to a string so we can manipulate it
                    fullPath = String(f[i]);
                    //find the position of the last / to indicate where the filename starts

Moving automator input windows to frontmost position

Is there any way of specifying an automator input dialog be placed in the frontmost position? At the moment, several of these inputs pop up behind other windows, so I have no idea that they are there. Seems like a curious behaviour to even allow, let alone be the default action!

Dialogs won't appear if the application they are from is not currently in front (active). If you are running the workflow from Automator, you can use the Launch Application action to make Automator the active application.

Why doesn't the input file dialog prompt once I attach it to a device?

For my project I am require to move a 3-axis robot from a list of set co-ordinates to either cut into/draw a picture. The only way I can thnk of doing this is by reading the co-ordinates from a spread sheet and timing it to read the co-ordinates and send the information to the straight-line move function (Softmotion).
The problem occurs once I try to run the program while it's connected to the devices (motors). The file dialog prompt no longer shows up and Error 43 shows up right away. I traced the problem to the read from spread sheet vi, but I am not sure what to do because it is a standard function in labview.
If you could take a look and give me some input it would be greatly appriciated, I've been learning labview on my own for about a month so if you can please use simple explinations.

Thanks for the help so far, so I did as you said and added a set path for the program to retreive the file from. I've tested the program by running it in my computer and the file reads properly so my assume is the file is being located and data is taken properly.
But I still run into the same error when I run it in cRio. I'm still being told labview cannot locate the file.

Canon 1DX support was added to ACR in version 6.7, 7.1. An updated CS6 should be at level ACR 8.6. If your ACR is not at level 8.6 try using CS6 menu Help>Updates. If that does not install ACR 8.6 try downloading the ACR and DNG 8.6 converter and see if ACR 8.6 will install into your CS6.

File dialog with multiple custom patterns

I am in need of being able to user select multple file patterns (*.bin, *.exe...) in a file dialosg similar to the express File Dialog VI where it lists the directory and allows the user to select multiple files from a windows dir listing. The express VI has a patterns input that takes multiple patterns separated by a semimcolon but there appears to not be a way of providing a ring control for file type and letting the user select the pattern that he wants to filter the directory listing with. I.E> > If the user wants to only load files that are *.bin, he only wants to view them in the listing. How can I do this without mutliple dialog boxes?
Solved!
Go to Solution.

Off-the-shelf might be something like a list box that allows multiple selections. Or you could drop a cluster of booleans on the FP and parse the selected file types and place ;'s between them. You could have multiple string controls that the user inputs the file extension and then you programmatically insert a ; I can't think of something off-the-shelf that easily does what you are looking for, these suggestions require a little bit of programming but should get you off to a good start at least.
This is the approach for choosing any desired types from a list. If you want to choose only one, use a ring or combo box or enum... Much simpler when only choosing one of many.

Open File dialog in 1.1.0.21

This is an old issue which I thought was supposed to be resolved in 1.1, but whenever you go to the open file dialog, it still always starts in the installation directory. It does not remember the last directory used and I cannot find anything in the global preferences that enables you to specify a preferred default location. There is a feature request that is marked as complete in 1.1 which kind-of covers this issue but relating to saving files, but the behaviour of both the save file and open file dialog is the same as it was.
Using build MAIN-21.41 on windows xp.

I too was disappointed that this promised enhancement was left out of version 1.1. However, I found a workaround that helps minimize the problem.
If you have a Windows Explorer window open to the folder where your SQL file resides, you can drag-and-drop the file into SQL Developer to open it. The trick is that you must drag your cursor to the tab bar area of the SQL Developer window to get the file to open in a new tab. Dragging it to the editor section of the SQL Developer window will not open the file.

Open File dialog window when setting the value of a path type input argument in a VI call

Hi,
I am new to TestStand (running 4.0) and I want to create a sequence of VIs to turn on, setup and measure a device. One of my VIs sends a configuration file to my device. An input argument to this VI is the path of the config file. I would like to make it simple to modify this path when setting up the sequence by popping up the File Open dialog window and choose my file. Is this possible? I do not want to manually change the file during execution, just to have multiple calls of one VI, each call opening a different file according to the path given to it during the setup.
So far I have only succeeded in manually entering the absolute path each time I add this step. What makes it even more annoying is the fact that LabVIEW interprets the path with the escape codes, rendering the path unusable. Manually adding a 2nd backslash at each '\' occurence adds another step to the process. I tried both String and Path type of inputs, and the SearchandReplace() or ToUpper() (trying to bypass the escape codes) functions in TestStand don't seem to help m.
Your help is very much appreciated,
Fred

Eudaemonic,
If you want to create a series of easy to configure step types so others can develop sequence files easily, you could use custom step types. When you create a custom step type you implement your own configuration dialog. Since you have control over what controls you expose in your configuration dialog, you can design it so the desired path is selected using a open file dialog. Refer to chapter 13 of the TestStand reference manual for more information about custom step types.
If you do not want to create a custom step type but you still want to give access to your sequence developers to pre-configured steps, you can use templates. A step template is a snapshot of a step that you can reuse later. Let's assume that instead of asking your users to edit the step to enter the desired path, you create several step templates with different pre-configured paths and based on their applications requirements they could use the appropriate template. Refer to the NI TestStand Help for more information about the Templates list on the Insertion Palette.
Hope it helps.
Antonio Lie.

Please fix: Common Open File Dialog Box to support Favorites (Follow-up: Better provisioning in the Windows client)

One more thing:
What's missing is favorites is a way to use the favorites space in the Common Open File Dialog Box.
Please obsolete or (re)develop components in Windows, so those components support any new workflows in Windows!
On example of an application where you cannot use Favorites is Adobe Photoshop. It uses the Common Open File Dialog Box in Windows (which does not support Favorites).
Comparing Finder (MacOS) with Windows Explorer - you "seem" to have the option of using favorites to pin folders.
Well, if your application calls Windows to use the Common Open File Dialog Box - it's actually NOT POSSIBLE AT ALL to navigate to the user concepts (user folders) pinned to favorites.
Again, the favorites namespace is completely unused (not provisioned) out-of-the-box. That's may be ok, however it's not fully implemented across Windows and just another example of stuff accumulating up to being unusable.
What's missing is favorites is a way to use the favorites space in the Common Open File Dialog Box.

Open File Dialog - JSP pages

If I create a jsp page with an open file dialog will it work no matter what OS people are running? What I want to do is attach a file. It would be preferrable if I could set a "working" directory and when I open up the dialog it starts in that directory. It has to work with Windows, Macs, and Linux . If there is no way to set the "working" directory, can a cookie be created that remembers the last directory accessed from the page so that when they open up the dialog it opens up under the last directory accessed?

there is a html input type that sparks up the OS native filechooser. Thus, it should be platform independent. You should look into Apache Commons FileUpload, as it makes the process of uploading/sending files ridiculously easy.

File Dialog and Report Generation Toolkit

Hi,
I designed a VI for an electrometer calibration and it works quite well The only problem I have is the following:
I used the Report Generation Toolkit to put the measurement data in an Excel file. When I run the VI I'd like a window to pop up to define the location and name of the Excel report file. If these two things are done LabVIEW should create the specified Excel file and run the rest of the code.
So i tried this with the "File Dialog" Vi and all the needed low-level File I/O VIs and it worked.
But when i connect the "File Dialog" VI with the "New Report" VI of the Report Generation Toolkit I get an error message.
Is there any solution to get this file dialog pop up window with the Report Generation VIs?
thx for any help...!

What does the open file dialog do 'under the hood' and is there a way to simulate it

What does the open file dialog do 'under the hood' and is there a way to simulate it?
I have a bug in my code (that I've posted about before, here) which I can't fix at the moment, but I do have a workaround.
Briefly, the bug:
I call a dll from a function node, to initialise and run a spectrometer. If I start up the PC, LabVIEW and run my vi the code runs without complaint, the first call to the dll to initialise the spectrometer doesn;t return an error but the spectrometer is not detected either.
I've tried various solutions, see the link above, and none work
The workaround:
If, at any time before running the code containing the function node I open an 'open file' dialog window, select the dll and click ok/hit enter then everything is fine. When I run the main code the spectrometer is detected.
I use an express vi to open the file dialog, I specify the start path and file name as constant inputs and just click ok/hit return when the dialog pops up. I don't do anything with the dialog outputs. In fact the vi that contains the open file dialog can be run before the project containing the bug is even open.
I have to do this everytime I turn the PC on.
So, either
1) Can somewone suggest a fix for the original bug?
2) What is the easiest way to simulate the enter keypress when the open file dialog pops up
or
3) Can someone tell me what the open file dialog does under the hood that somehow causes the dll to work and can it be simulated in straight LabVIEW
I suspect that the dll itself is dodgy ( I have in the past talked to the supplier but not got very far, and I will try again but I would like a quick, temporary solution too). I'm guessing that the file dialog is making some kind of check on the file, and possibly registering its presence with the OS (winXP). I tried using the file/folder exists vi to see if checking the file like that worked but no luck.
Any help greatly appreciated.
Dave

Hi David
I am very conscious about thread hijacking but this sounded like my issue so I hope you dont mind me asking about your issue. I am hoping that you have a spectrometer from the same vendor as me and its not just me seeing an Error 1097 issue. My spectrometer is from a company called Stellarnet.
So far I have unable to get it to work with other VIs. There is one condition where I can get it to work but its no good for me.
Case 1
I open the VI in a fresh labview environment with no other VIs in memory. The code runs with no issue.
Case 2
Labview is not opened. I double click the spectrometer VI in windows explorer. The VI opens but it fails to run resulting in Error 1097. Personally, I dont see the difference between this and Case 1 above and yet it fails.
Case 3
If I already have other VI's in memory and try to load the spectrometer VI and run it fails with Error 1097. This case is the one that most important to me. I have a test executive that will load test VIs dynamically and I can't get this to work. Same problem Error 1097.
I wanted to share what I have seen with you and to let you know that maybe somebody else has the same issue. I am convinced its the DLL but the vendor dis-agreed saying it was LabVIEW. I couldn't convince him otherwise.
Thanks in advance
David
