Yes..like that . How did you get the time stamps on the grid lines???

I want to make sure each gets a time stamp

thanks

J

As Asbo said. You have to select a scale that shows the minor markers.

I think I see.

Like this?

I am using LV 8.5.1, so I cant open this VI.

Hopefully in your solution, there is a running time stamp for each major grid line....grid lines will move from right to left

Can you post a picture, since I cant open your VI

J

Sorry.

Here it is in a version you can open.

Hello

I am using a Waveform Chart and I would like to display the running time stamp on each major grid line. (LV 8.5.1)

Anyone know how to do this? A picture or a small vi would be quite helpful

thanks!!!

Here you go

Isn't that what you'd expect?

Its what I expect since I think of refs similarly to pointers. An unitialised pointer is a "null" pointer (no memory allocated). But I think Daklu thinks of them as references to objects and that by placing it on the diagram the "pointer" is allocated. So I got the impression (rightly or wrongly) that he expects a reference to an uninitialised ref to be the same as an initialised one since it is the same object. In that respect. Daklus last image seems prefectly normal to me, however it is an "unexpected" result.

In other words, the equals prim is smart. It "knows" to compare values of by-val objects and to compare references of by-ref objects.

...eh, I thought it was a neat side effect.

I'm not sure its is that smart. It basically just typecasts the ref to a U32 (or maybe an I32) and compares the values. It does the same for VISA and IMAQ sessions. If you think about your uninitilaised references, the value when typecast is 0 which is not equal to its value if its initilaised.

The cFP-1808 module backplane controller has a small hole labeled "RESET" that just begs for a straightened paper clip to be inserted.

The question is: (a) What is it that is RESET? (b) To what state is it RESET? and © Now that it is RESET, how do I put the reset values into some state of my choosing?

Its more of a reboot than a reset. The state depends on what you have set the power-up states to be from MAX and the position of the DIP switches (refer to the manual)

Thanks. I suspect it should work. In my case it got up to ~350 VIs before Labview sputtered and died.

Told you I get confused as to which propery nodes need closing of the refs

In a quick test just now in 8.6, it does in fact reload from disk VIs it does not consider to be changed.

Sweet

You can't help but laugh AT them in this

When working on a project sometimes another developer will check in code and I'll want to get the latest updates. Or I might be futzing around with previous versions of certain VIs. Usually LV will catch it and tell me the VI on disk has changed and offer to load the disk version. Sometimes it doesn't and continues to show the copy in memory rather than the version on disk. When that happens (or if another devoper has updated the project file) I end up having to close and reopen the project, which takes ~8-10 minutes.

I'd like to have some tool that forces LV to reload the project file and any VIs, controls, libraries, etc. that are in memory from disk. The Revert method combined with getting a list of all loaded VIs might work. Rereading the project file might be tougher.

Try this

Although I don't know whenter it will reload the vis if the vis in memory aren't modified. LV might ignore it if it doesn't think anything has changed.

But you should really be checking in/out and merging since its really a source control issue.

Is there a way to force Labview to reload a project file and/or project VIs from disk? I scanned through property and invoke nodes but didn't see anything promising.

Not quite sure what your getting at here since the project is just an organiser. You can set a directory to autopopulate which will cause it to react when changes to the organisation take place.

Individual vis can be reloaded by selecting "revert" which forces a reload from disk if the vi has changed (you can use an invoke node for this).

I'm glad you asked - they're right here. Sumission instructions are here.

Interesting. You don't get any of those when you click on "Code Repository" in the menus at the top (the way I went )

That's right - your submission has to be reviewed and approved by a "LAVA Certified" team member. It's one of the strengths of the LAVAcr over other forum reposotories - we only let code in that meets the LAVAcr standards.

And these " LAVAcr standards" are documented where?

Link is borken.

I think it needs to be approved or something. It doesn't appear in my file list but I can see it in the repository and edit/download etc (and its a different colour to the others). If I click on the link its there, so must be just the uploader until its approved.

Hi,

Can Anyone Know about how to program Analog Devices BF561 Ez-LITE Board board with Labview, means How to start programming using that board using labview

You'll probably need the "Embedded Module For Blackfin"

Hi,

I am working with Multicolumn Listbox, and I want to change the display method of one column of the Listbox to those like password display (i.e ***), but I do not know how to achive this.

Besides, I want to insert a combo box in one colomn for each element so that customer can input easily, can any body help on these 2 issue?

The short answer is you cannot. You cannot change the text attributes of a single column/row and you cannot embedd child controls into the cells.

What you can do is make it look like that is what it is doing.

For thee password display, you can replace the text after the cell is edited using the event structure. You will have to keep another copy of this column since you will be overwriting the cell contents.

For the combo-box, you can overlay an array of menu-rings or enums. You will have to manage resizing if that is required.

Same here.

Watch this space insted.

PassaMak

I should have make it more clear but the XControl I linked to uses the windows messages for this.

Well. Yes and no. It uses .NET so its a bit like saying a vi creates Word documents when, in fact, it is an automation interface to Microsoft Word and Word creates the document. No word, no document. No .NET, no messages.

Well. What can I say. It'd take me a week to figure out whats going on in that spaghetti.

I would suggest thet you keep the diagram open while running and when it no longer responds, click the "Highlight Execution" button (the lightbulb). That will show you where it is currently executing. That will at least narrow it down.

Sounds like a very good application for LabVIEW.

Here's a simple example of implementing this.

Be even better if we could catch windows messages in the event structure!

Hello Boy!

I am italian, sorry for my english...

I have a big problem and I do not know how to fix it.

Using LabVIEW 8.5

My program is for the management of machines voltage regulators, i communicate with them via a USB-RS485 on Modbus, The questions I wished them and so far no problem.

stores data in a spreadsheet excel and do extensive use of blocks "read from measurement file" and "write to measurement file" about 30 times that i frequently rewrite about once every 2 seconds.

Now I go to my problem: after that the software go regularly he stops suddenly.

No longer works in labview converter but I do not return any error message or something.

At this point I press the stop button and i restart the program and everything starts, until a new stop.

My fault, software, or the converter??

thank all

Can you post an example that demonstrates the problem?

The last job I did that required translations had a bunch of them, and the file format our translation code uses was compatible with the output we got from the translation services (they would give us an Excel file, we would save it as tab-delimited ASCII and we were done).

Same here.

Watch this space.

It certainly took some effort to make the editor. Hopefully it gets some use. The nice thing about a single file is transportability. Also grouping translations into resources helps with accessing data if you want to change the language setting at run-time. Plus the editor helps you organize resources into folders, so all the controls for a single VI can go into folder. Just makes it pretty.

Indeed. From the usage point of view it look on the face of it to be nice and easy to access from within the code and you certainly have created a sleek interface.

I'm not sure how time consuming it would be to create 5 translations for 300-400 controls though. Also, what if (as in my case) the developer is not the translator?

Ah, right. I missed constants on the terminations...

That'll be the next problem You must be in an earlier timezone from me...lol.
