Path control dialog on FP

How do make my path control pop-up say "Open File" instead of "Save File". My path control dialog always opens with a dialog titled "Save As" in the pop window title. When the user clicks on the path control browse button I would like the title on the pop window to say Open File. My path control is not wired to anything I use a reference to read its value and send the path to an external application.
I notice if I wire the open-file vi to my path control the pop-up will show "Open File" but wiring the path control is not necessary in my app.
Thank ahead of time for responding

OK, I can answer my own question. I put a File open vi on block diagram, create a file open control and replaced my path control (Save file) with the File open control. walla

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):

Browse Path Control: Selections Not Found or Displayed

Selecting the multiple Pattern: *.xls:*.xlsx below from Path Properties does not produce the required files I am looking for, can someone point me in the right direction? As you can see from the attached, Only selecting 'All Files (".") delivers the result I am looking for. I have already pursued the following link with the same results. http://forums.ni.com/t5/LabVIEW/Add-multiple-selections-for-pattern-label-in-file-path-control/m-p/2.... I have also tried using the File Dialog Express.vi and Open/Create/Replace File.vi.
Thank you for helping me address this issue.

Using a semicolon instead of a colon works for me.

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.

jimmy.chretien wrote:
[...] 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 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.
Solved!

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:

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.

Trigger&Gate Express VI. Is it possible to control Dialog Box parameters on the frontal panel?

When you use a Trigger&Gate Express VI the Dialog Box Options permits you to configure the VI. I am asking if it is possible to control Dialog Box parameters with controls on the Frontal Panel. I am especially interested on Start Level Threshold.

open the VI that the trigger and gate is in. Right click on the express VI and select open front panel. Then find the control that you want and edit the connector pane to be able to input the parameter that you want. Attached is a modified version that I came up with for you.
Hope this helps you.

Send path control or reference to path control to sub vi

Hello! I have a question of how to build correct labview structure. I have a path control in my main vi and want to check if it is correct in a sub vi. If not correct, ask the user for a correct one in the sub vi. I see two different options of how to do it and I think no one is realy good.
1. Draw a wire from the path control to the input of the subvi. The answer from the sub vi is connected to a local of the path control. This uses locals that I should not use.
2. Draw a reference from the path control to the input of the sub vi. In the sub vi change the value of the reference if path is not correct. No output is needed. Using reference you do not see where variables changes.
How should I solve a problem like
this?
Please help me!

Local variables are fine. Don't worry about using them.

Why does Firefox 33.1.1 require a User Account Control dialog before loading?

I am unable to stop FF from requiring the User Account Control dialog box before it will load. I uninstalled and reinstalled a clean copy, which worked the first time, and then re-established the UAC dialog on subsequent starts. This is incredibly annoying. It has never happened before with FF. How do I stop this behavior? I will stop using the damn program if this can't be fixed.

Check that Firefox isn't set to run as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
* Privilege Level: "Run this program as Administrator" should not be selected
* "Run this program in compatibility mode for:" should not be selected
Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\).
If you can't make the changes then you need to start Windows Explorer as Administrator.

Something similar to browse path control, but not quite

Hi all,
in my VI there is a 2D listbox. When I click on a line, in a subpanel a VI is loaded and data from listbox is written into controls in this subpanel. The VI in the subpanel then is finished.
A "browse path" control in the subpanel can be pressed, a new window is opened and I can choose a path, even though the subpanel VI is not running.
Is there an option to have a custom control, where I can open e.g. a new VI when a button is pressed? XControls don't seem to work or I am too stupid.
Thx in advance

Hi Tesla,
customize a boolean button to show the same image as the browse button of the path control. Then you can call your own subVI when that button is pressed…

PATH CONTROL? Selection of, changing fill and stroke colors, moving & arranging? WHEN

When is "Ideas" going to have BASIC, vector and path controls???
The ability to select, move and arrange individual paths?
The ability to fill and change stroke colors?
Shape tools?
I would've expected this from the start. This is not 1988 all over again... or is it?
And what's this racket with "layers"? You charge a premium for the app and then want people to pay again for simple features? Layers would be less important if the app could do what it should to begin with.

Hi Mark,
Please post ideas for improvements using the Submit an Idea button, please post each idea as a separate thread, this is so others can vote on the idea if they had the same one or like the idea, The product team reviews these when considering what features to add.
I'm not really sure why Adobe has the option for additional layers as an in app purchase but you could create an idea post to request this changed as well.

Time stamp control dialog kills System Exec.vi !

Hello!
I just experiance a really strange behaviour in my application. I managed to reduce it to a much smaller VI, please do not look at the framework but at the actual problem, this test MAIN vi looks like this since it is a skeleton of a bigger application (i had to remove many non-relevant and confidential parts).
So. I have a USB watchdog relay from a 3rd party company, which I can use perfectly in my application via a supplied EXE. I call this exe from LabVIEW using the System Exec.vi , and it works perfectly and the Watchdog functions as it should. However I see a strange bug (?): if I launch a Time stamp control dialog browser window, it "pauses" somehow the System Exec.vi. So my watchdog command setting stops, relay opens, problem!
I zipped my test application and I can reproduce this same problem even if I just call a command line PAUSE win command. Note that, in my real application, the Time stamp control is located in a separate, dynamically callled (call and forget method) VI, but I get the same bug!!!
Steps to reproduce the bug:
start my application
observe as the bottom loop iterates
Click on the Time Stamp control's browser to pop-up the dialog window.
You can see the iteration of the bottom loop stopped (DAQ loop iterations)
if you close the dialog window, the bottom loop continues execution
What the heck is this???
How is this possible, why there is "interference" between a totally separated control and a bottom loop System Exec.vi ???
Thanks for any suggestion!
In my real app, as a workaround, I just hide the browser element of the Time stamp control...
Solved!

Thanks! Yep, I can do a workaround, like create my own time stamp dialog window to pop-up if i wanna be "fancy".
But this is important to keep in mind, if we use the SystemExec vi!
If someone can explane this issue/feature deeper, I will be happy, but I mark this above post as solution, thanks!
