I am unable to print the block diagram on a HP1055CM DesignJet.
The print manager shows it went to the printer but all I get is a blank page on the printer. Is it maybe a font problem?
There are many things that can go wrong when you print.
The first thing to try is if LV is generating the proper draw instructions for the printer. Try to print to an HTML file (this is one of the options toward the end of the File >> Print dialog), and see what the file looks like.
Typically, print error occur because of the printer's driver. Check to see if the driver for the printer is the most recent (by looking on the printer manufactorer's website).
Use this link to an article that details printing problems, and their solutions: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/0a124f6b3a94a82f862569680071cd48?OpenDocument.
It will walk you through what to do, and has a VI attached that will extract your printer information
if you are still having an issues after trying the things detailed in the knowledgebase.

Unable to print the report after SP2 (CR 2008 / VS 2008)?
I'm developing an ASP.NET application using VS 2008 (Framework 3.5). I have installed CR 2008 with SP (0, 1, and 2).
I created an invoice report and I printed it as test for the report and it works okay. I needed to change the page size of the report to a user defined size and reset all of the margins to zero.
After I did that I was unable to print the report again and every time I tried to print the report nothing gets printed.
I checked my environment to find the cause of this problem but I found nothing except that I'm using CR runtime for SP1 and I'm currently using SP2. So I did remove CR runtime for SP1 and install CR runtime for SP2.
The problem didn't go away and I faced one more problem.
Usually I'm using a dataset as a data source for my reports. After installing the CR runtime for SP2 I couldn't see any date column in my report data source (Dataset). All other types of columns appear except date fields! Why I have no Idea?
After I do some more testing regarding my issue I found out the following
1. When I add a new report to my web application and I don't change the page setting the report work fine.
2. When I change the page setup settings (Page Margins, horizontal width and vertical height) the report show up okay but never gets printed.
Why I don't know?
Addition to that the report dataset (Data Source) showing in the field explorer never shows any date type field?
All of the above issues happened with me after installing SP2.
OS: WindowsXP Pro SP3
CR 2008 (SP 0, 1, 2)
VS 2008 SP1
Please I need your help.

Are you printing from the Crystal preview window, or in code?
If you are printing from the preview window, try printing via code, such as:
An example of print to printer:
crReportDocument = New ReportDocument
crReportDocument.Load("h:\labels2.rpt")
''Use error handling in case an error occurs
Try
''Set the printer name to print the report to. By default the sample
''report does not have a defult printer specified. This will tell the
''engine to use the specified printer to print the report. Print out
''a test page (from Printer properties) to get the correct value.
crReportDocument.PrintOptions.PrinterName = "
dwcb12003\ZDesigner ZM400 200 dpi (ZPL)"
''Start the printing process. Provide details of the print job
''using the arguments.
crReportDocument.PrintToPrinter(1, True, 1, 1)
Please post your question about the dataset as a new post.

How can I open a vi and show the block diagram?
Hi,
I am opening an vi using "Open VI Reference" and "Invoke Methodpen FP", but I want to open the vi and show the block diagram, but I haven´t found any method (Invoke Method) to do that and any property.
Any idea?
Thanks!
GracindaOK, I can come up with a reason. I have written a program that will search the entire VI Hierarchy of a program and update all of the descriptions for all VIs with the top level program part #, the name of the top level program that the VI is used in, the company copyright info, the ITAR notice, company address, the name of the engineer performing the update, along with the date and time. This will also place as a background image on all the VIs, a watermark of the company name, legality stuff and the copyright. It works very slick in that if there are thousands of sub-vis, such as what I'm working on now, it goes through all of them, makes sure the data is there as per company policy without having to open every one of them look at them and update or not whichever the case may be. The one portion that is tough is that the program will detect if there is a description written about what funtion the VI performs and if there is not a description, then it pops up a dialog requesting the user to write a description. The problem is that without looking at the block diagram for the VI, it can be nearly impossible to write a description for the functionality of the VI. So is there a way to programmatically open a VI, show its block diagram (this would only be in the case of a missing description) and then upon completion of the updates, close the block diagram? (I already open and close the VI programmatically in order to read the VI DESC and update as needed, but that is in the background and of course you can't see the block diagram).
Thanks,

How to add text to the block diagram
How do you add plain text to the block diagram for documentation and can I change the background color to yelllow or something else that may be helpful? see image below
Windows is a 64 bit extension to a 32 bit graphical shell for a 16 bit patch to an 8 bit operating system originally coded for a 4 bit microprocessor, written by a 2 bit company that can't stand 1 bit of competition. Byte that Microsoft!

Go to Solution.Just double-click in an emtpy area and start typing. Use the coloring tool to color the text background.
(there is also a "free label" in the decorations palette, but that seems like a detour )

LabView application hangs up when scrolling the block diagram
Hi all.
I attached you "Main.vi" that is part of my LabView project. I don't know what's going on, but when I scroll the block diagram to the maximum right, the LabView application hangs up. There are a lot of things in this block diagram because is an outline yet. My plan was to make it more structural, but now I can't do anything because this error don't allow me to edit the diagram.
Please, try to open it (ignore all the dependencies) and check if it hangs up also in your computer.
If it does, is there any way to recover it? It's really important for me because I don't have any backups since two weeks ago...

You might have video card issues. Try this: open the VI, and hit Auto Cleanup, then save. Close LabVIEW, reopen. If that does not work, try to get to the far right side by going to the Front Panel, and double clicking something that will take you there. If you get there successfully, use the disable structure to disable ~ 1/8 or more of the diagram on that side. Save, reopen.

Cannot place custom subVI on the block diagram
When I press the "Select a VI..." button on the function palette and select the VI I want to place on the block diagram nothing happens. This only seems to be happening for two particular VIs. Most of the time I can place the custom subVI without any problems.
Is there some option that could have accidentally gotten set that does not allow a VI to be placed on another VIs block diagram?
Please let me know if there is any way to fix this problem.
Thank you,
David R. AsherDavid,
What you sent me has a .ctl file extension. The ctl extension is for LabVIEW custom Controls, not VIs. Even though it is actually a VI, the wrong extension must be confusing LabVIEW and not letting it load. It's probably trying to put it on the front panel since that is where controls go.
If you change the ctl extension to vi, it works as it should.

The Block diagram that cannot be edited...
The customer wanted to launch the application ( done in LV7 ) with a shortcut from the desktop and when done with it wanted to close all including the LV environment.
So I made the following changes :
1. Made the application to "Run on Open "
2. Connected the while loop Stop button to the "EXIT" function.
3. Saved and started the application.
Presto!! All worked as expected. Except that I no longer was be able to Edit the block diagram !!
Good - I had a copy of the code before the change and survived the nightmare ....
So the moral : Be very clear of what you are doing before you use the EXIT function.
Just though will share the experience, before somebody makes the fatal mistake as above.
( I have now ordered out my copy of the Application Builder, so that I can have my editable code well away from the customer's PC.)

LV2012 to Automate Hydraulic Test rigs.Here's another way to do it.
Create a directory in your LabVIEW x.x directory named 'wizard', and save the attached VI there. If LabVIEW is running, you'll need to restart it, but then in the 'File' menu, you'll have a new selection named "Supress Run on Open...". Select this and you'll get a browse dialog to select the VI to open. It opens it by reference so it will not run.
This is saved in LabVIEW 6.1, but works fine on 7.0 and 7.1.

I cannot display the block diagram when the VI is running
It is not possible to show the block diagram while the VI is runs. The frontpannel remains on the screen. When the VI is started from the block diagram, the frontpannel pops up and stays on the screen
Are the VI Properties >> Window Appearance... set to dialog or modal? That could keep the front panel on top.

Why Is the Block Diagram Disabled?
What did I do now? Please look at the attached image. A VI that I am using as a subVI in various different programs suddenly started looking like I had used application builder to create an exe file out of it (But I didn't!!). The only options are Start and Run Continuously, and the block diagram is disabled. What did I do to get myself in this mess? How do I undo whatever I did, so I can edit the block diagram again? Any help or suggestions would be greatly appreciated.
Thanks!

Disabled Block Diagram.png 259 KBDid you ever built a source distribution with the option set to remove the diagrams? In this case, the original must still be around somewhere.
Since LabVIEW 8 you can no longer simply save without block diagram and you would not be able to upgrade such a VI to LabVIEW 2011, which it is now. (details)
Of course it is possible that there is some corruption, but looking at the memory usage, the block diagram is blanked out.

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?No. The Label Visible property is separate for the front panel control label and the block diagram terminal label.
How did you start out with the block diagram's label not being visible? Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default. Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it. I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.) I've gone to the BD and right clicked to show the label. Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing. When I add some text to the label, at that time, I find both the BD and FP labels become visible.
Are you dealing with controls that have empty labels to start?
Good programming practices:
1. Always have a name for all of your controls, never use and empty label by deleting the text in the label.
2. Make the labels unique. For example, don't have two controls both called Stop. How do you know quickly know which terminal relates to which control?
3. Always show the labels on the block diagram, so you know the function of a control's terminal. If you want to hide the label on the FP, that's okay.
4. If you want a different label to appear on the FP than whatever you actually called the control, then use the caption. You can hide the label and show the caption. This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language. -
Disable (all) functions on the block diagram with right-click menu
Hello to everyone,
here is one more idea, which I'd like to propose.
As for me, it would be useful to have the following: when all components (functions, wires, subVIs, etc.) are selected on the block diagram (like, after ctrl+A), operator could do right-click, and in the menu would appear menu item "Disable everything". After it, all the code could be placed into Disable structure.
Of course, I can add Disable structure to block diagram manually, and cover whatever I want, but with right-click menu it would be much faster.
Also, it can be modified to disable only selected items - then each of them can be placed into separate Disable structure, and, for example, additionaly in the enabled case of Disable structure, corresponding wires will be connected. Sometimes it is needed for testing - just to disable couple functions, and test subVI. Or to disable subVI fully (it's faster, then disable place, where it is called. Especially, if subVI is used in many places).
It will not make debugging difficult, because anyway Disabled structures are used; such functionallity can just make life a little bit easier...
There is always the File->New... which opens up a new window. You can have your templates in that window by putting them somewhere (I don't remember where at the moment).

What is the best way to keep the block diagram/ front panel clean?
Hello,
I am relatively new to Labview so I'm not able to tell if I'm overcomplicating my programs or making my block diagram too cluttered. I was wondering if there were some ways to tell whether I could simplify my programming just by looking at it (perhaps only experience helps for these things) ?
I have attached my VI here. Currently, it has the capability to monitor the voltage and current from two motors. On display, you can see a indicator with the voltage and current values and there are charts toward the bottom that can display waveforms from different motors with a drop down menu.
The front panel is rather clean in my novice opinion, but the block diagram seems messy to me, just at first glance. I foresee a problem occuring in the future however. In the future, I will have to scale the VI to monitor 50 motors. All the programming will be the same as the one I have now, except it will have 50 indicators and unfortunately 50 times pretty much everything. I would like to avoid this, but I'm not sure how I could.
I am using a USB 6009. I am using its four differential inputs to monitor the voltage and current of two motors. In the future, I will be getting more DAQ units (25 total because 2 motors can be monitored for each DAQ). The new DAQs will help will help with more resource space, but I think complicate things with the additional potential of 24 more DAQ Assistants (as used in my code).
Thanks for any help you might be able to provide!It usually is mainly experience that will teach you the best methods to make your code look pretty. I don't know anyone who is proud of their first from-scratch application. There are a few resources out there to help with best practices, like this group on ni.com, but you'll learn the most from your own development.
Your front panel looks great. FPs in general are really up to you. You can make it look as ugly or pretty as you want. When you have some duplicate controls and indicator groups, you should utilize clusters and arrays to simplify. You could use a little bit of cleanup in that regard, but not much. Also, personally, I hate reading red text unless it's a warning of some sort.
Your block diagram could use some cleanup in a modularity sense. You have a lot of repeated code, which you could consolidate in to a subVI that is used in multiple locations, or in a For loop. A general rule of thumb is to keep your block diagram within a single monitor. You shouldn't have to scroll. Your application is pretty simple, so it's hard to mess it up
Here are some specifics about your block diagram:
Right click your terminals on the block diagram and uncheck "View As Icon". You're welcome.
Duplicate operations on each waveform "(x*2-4)/16": create subVI and/or run the waveforms through a For loop.
You do a lot of 2-element arrays and then indexing. Just replace those with a Select node based on the numeric.
All of your code is running every time, including your property nodes at the bottom, which is unnecessary. As you learn LabVIEW architectures, you will learn how to bypass this with initialization and exiting code, but for now you should put a case structure around those for only when the motor numbers change.
I'm not sure how you're timing your main loop, but you should put a delay in there because you don't need the DAQmx node to be pulling as fast as your CPU will allow.
There are free intro videos you can watch to learn what NI would suggest in terms of coding and teach you some of the basic features and such. Here's a three hour course, and here's a six hour course. -
Place an image on the block diagram
Is there an easy way to place an image on the block diagram?
To clarify, I would like a simple way to paste a bmp or jpeg or png or whatever onto my block diagram for the purpose of documenting the block diagram for future programmers.
The way I currently accompish this is by creating a picture constant on the diagram and running a seperate vi to load a picture into a picture window, then using copy and paste functions to get the image into the picture constnat in my block diagram.
There's a simpler way, right?

Go to Solution.Thanks, but that isn't at all what I am trying to do. I want to

screen shot of my block diagram to show you that I am using an image
that I pasted onto the block diagram to document the block diagram. The
picture below the wiring is a schematic of a rectangular reticle that
corresponds to the wiring diagram above. You can see which points go
where when drawing the targeting reticle around kermit the frog, so it
is easier to understand the wiring diagram.
The method

would like to know if there is an easy way to paste an image into the
block diagram.
