How to open an excel file from labview?

I tried to use "open file" vi from File I/O -- Advanced file functions to open an excel file in LabVIEW. Why the excel file wouldn't open after I run the program?

In addition to ActiveX, you can also manipulate Excel data files using the Windows ADO interface - a technique that is more robust, faster and IMHO easier. Do a search on the forum as there have been several threads within the last week or so discussing this very thing.

Can I open a excel file from labview

I have a program who write temperature in a excel file and i want to open this file from labview .

This depends slightly on the amount of data you have stored within Excel.
You can use the "Labview Functions>>FileIO>>Read from Spreadsheet file.vi" which effectively reads all lines from a text file and converts it into a numeric array.
Alternatively, if your data structure in Excel is more complex than this, you can use ActiveX calls to Excel to retrieve it.
Use an "ActiveX>>Automation Refnum" control and select the Excel server class. This will then enable you to access properties and methods of Excel to retrieve data from specific cells and pages.
The attached example should help.

How to open a .MAT file in LABVIEW

Hey everyone,
I currently have a .MAT image file which I would like to open in LABVIEW to apply some image filters. However, I am unsure as to how to open the .MAT file in LABVIEW. Ideally I would like to be able to open the .MAT file without using matlab, and it seems the only way to accomplish this task is through the mathscript node. I have attached an example of the image im trying to open, as well as the LABVIEW program which I would like to use on the image. Thanks for the feedback! =]

Hi Boiler,
1) Do you have a choice in the format you export your data from MATLAB?
"ASCII Format
Complete the following steps if you want to import or export data between LabVIEW and the MATLAB® environment, the process is straightforward as long as you are using ASCII format.
From the MATLAB® environment to LabVIEW
To save a vector or a matrix Xin ASCII format with tab delimiter, enter the following in the command window or m-script file in the MATLAB® environment:
>>SAVE filename X -ascii -double -tabs
This creates a file whose name is filename, and it contains the data X in ASCII format with a tab delimiter.
Import the file into LabVIEW using the Read From Spreadsheet File VI located on the Programming»File I/O palette.
2) Have you tried using the mathscript node? Did you get any errors?
"Binary Format
Complete the following steps if you want to import or export data between LabVIEW and MATLAB®.
From the MATLAB® environment to LabVIEW
To read a .mat file in LabVIEW would require a VI to parse the file. This may be easier if each variable is saved to a separate file.
" -- this was done here, no ideas if it still works,
I want to read a Matlab MAT file into labview
Hope this helps, James

How can I read pdf files from LabVIEW with different versions of Acrobat reader?

How can I read pdf files from LabVIEW with different versions of Acrobat reader?
I have made a LabVIEW program where I have possibility to read a PDF document. When I made this LabVIEW program it was Acrobat Reader 5.0.5 that was installed on the PC. Lather when the Acrobat Reader was upgraded to version 6.0, there was an error when VI tries to launch the LabVIEW program. And Later again when we upgraded to Acrobat Reader 7.0.5 I must again do some changes and rebuild the EXE files again
It isn't so very big job to do the changes in one single LabVIEW program, but we have built a lot of LabVIEW programs so this take time to due changes every time vi update Acrobat Reader. (We have build EXE files.)
The job is to right click the ActiveX container and Click "Insert ActiveX Object", then I can brows the computer for the new version of acrobat Reader. After this I must rebuild all the "methods" in the Activex call to make the VI executable again.
Is there a way to build LabVIEW program so I don't have to do this job every time we update Acrobat Reader?
This LabVIEW program is written in LabVIEW 6.1, but I se the problem is the same in LabVIEW 8.2.

How to open an external file in Labview?

Hi, Who knows how to open an external file in LabView? I want to open an .UDL file(data link API) which is a dialog window letting me input correlated database information, but I dont know how to open this type of file in my LabView Program.
Thanks.
Red

A UDL is technically a text file, so you could open it with "Read Characters from file", put the result string into a string control, edit it and save it back using the "Write Characters to File".
UDLs however have their own configuration dialog embedded in the Windows OS. You can use this dialog in your LabVIEW application. The attached VI shows how to create a new UDL. You can edit an existing UDL by switching the method node to PromptEdit and wiring in an open ADO connection reference.

How to Open Two Excel Files in Multiple Monitors in Windows 7

How to open two excel files in two excel windows using multiple monitors in Windows 7.
Currently it opens multiple files on top of each other on the same one monitor.
I found this article in a blog it says
"The snap feature that you are looking for will not work unless you open two instances of Excel. This is because Excel Unlike Word is not a True SDI Application. Microsoft is aware of the Issue however there is no resolution to the problem but the workaround"

If you are working almost the entire day in front of your computer at your office with lots of Excel Sheets and Word, then probably you might be working with a
dual monitor or may be even more than that. Studies have shown that having an additional monitor increases the productivity by 20 to 30 percent (Source: NY Times)
But some applications like MS Office Excel, even though you open multiple files, they are all from the same instance of the application. So if you want to compare two
Excel
files, then you may not be able to have it in two
separate monitors as the files are loaded using the same instance of Excel. If you move one
Excel
file to the other window, the other Excel files are also moved to the other window.
So how to have two separate Excel files or other application side by side in dual monitors?
Option A:
In Excel 2003, go to Tools -> Options ->
General tab.
Make sure the option, ‘Ignore other applications’ is checked. Now all the Excel files will be opened as separate instance and you can move the Excel files individually across the monitors.
In Excel 2007, Click the Office button ->
Excel Options -> Advanced.
Under General, check ‘Ignore other applications that use Dynamic Data Exchange’.
or
As this method forces each Excel file as a separate instance, the memory consumption will be more. If you don’t want too many memory consumption then you can open only two instances (see
Option B) and manage wisely to view in both the monitors.
Note: If you are having issues like Excel opens without displaying a workbook, then you may have to
uncheck this option. (See Microsoft Help for more details on this). You can use option B in this case. I have this option checked and I have not faced any issue yet.
Option B:
They key here is, the application has to be loaded as separate instances. Lets say you have opened an Excel file in
Monitor 1 and you want to open the next excel file in Monitor 2. You can usually open another instance of Excel by browsing through the
Start Menu -> Programs -> Microsoft Office ->
Excel. Make sure this newly opened Excel file is the last Excel file you had viewed and then double click on the Excel file that you wanted to open. This will force the Excel to
open
in the second instance of Excel. Now you can move these
two excel files separately across windows or monitors.
This may be little cumbersome way to open new instances of Excel every time. The easy solution would be to keep these links in the
quick links near the Start button. So, every time you want to open a new instance of the application, you can just use those quick links.
hope work thanks

How top Open a Excel Document from share point document library using jquery

How top Open a Excel Document from share point document library using jquery

Hi,
According to your post, my understanding is that you want to open excel file via JQuery.
To open excel file, we can use the following code.
<script type="text/javascript">
function openExcel(strFilePath) {
var yourSite = "http://www.yoursite.com";
openExcelDocPath(yourSite + strFilePath, false);
function openExcelDocPath(strLocation, boolReadOnly) {
var objExcel;
objExcel = new ActiveXObject("Excel.Application");
objExcel.Visible = true;
objExcel.Workbooks.Open(strLocation, false, boolReadOnly);
</script>

How to open Adobe Reader file from another native IOS application?

There is an existing thread, but I want to re-open it because I think this is an important feature that we need badly. I was wondering if there is any plan to add this feature so we can open PDFs directly into Adobe from the web / other apps.
How to open Adobe Reader file from another native IOS application?
Basically, we just want to use a custom URL scheme to open a specific document in the App. Currently, this only opens the app but does not load the file.
APB

Not to hijack the conversation but I can explain why this would be useful for both the above case and another.
What I believe Pavel is talking about is setting up a "URL Scheme" for the Adobe Acrobat iOS application so that you can easily open a PDF specifically in Adobe Acrobat iOS from other native applications and even from web applications opened within Safari. This is particularly useful if your application requires some of the specific features in Adobe Reader iOS to grant them the best experience possible and you want to encourage this.
Another case: If you're using Adobe Livecycle's document security modules (that encrypts PDF files so that Adobe Acrobat must "phone home" to decrypt and view the document), these PDF's can only be viewed inside the Adobe Acrobat application and appear as blank in most other PDF readers. Having a URL scheme allows your application utilising this functionality to have a 1 click step to view the PDF rather than the current non-user friendly process:
- Within Safari, touch the PDF link (appears as blank in the default Safari PDF reader, which in itself is confusing)
- Touch "Open in..."
- Touch "Adobe Acrobat"
We have an immediate need for this functionality for the example above. I can resubmit it in a separate post if necessary.

Why does TDM Importer start up when I open an Excel file in LabVIEW, and how can I stop it?

I have a new application using LabVIEW 2012 SP1. I open an Excel file using the Report Generation toolkit and when I do so, a small TDM Importer window pops up on top of the Excel file.
How can I prevent this?

Hi Steve,
The TDM Importer pops up because the report generated in LabVIEW is in the TDMS file format. TDMS is a binary file that requires an importer to make sense of the binary data and translate it into an Excel spreadsheet. As per this white paper, the appearance of the floating toolbar is expected behavior: http://www.ni.com/white-paper/5874/en/
To the best of my knowledge, you cannot get rid of the floating toolbar unless you uninstall the add-in, in which case you probably would not be able to open your LabVIEW-generated reports. However, as of Excel 2007, the toolbar is embedded in the "Add-Ins" tab instead of floating on your spreadsheet. You can see how the toolbar looks as of Excel 2007 in step 6 of this white paper: http://www.ni.com/white-paper/5885/en/
If there is a way to embed the toolbar in Excel 2003, it would be the exact same way you would embed any other floating customer toolbar in Excel. In other words, I don't think this has anything to do with the fact that it's NI's add-in. This is just the way Excel 2003 and earlier treats add-in toolbars. Someone on these forums may well know a way to embed it (perhaps a macro?), but you may have better luck contacting Microsoft. I'm not sure whether it's even possible for a user to embed the toolbar.

How to open a local file from javascript in a jsp-page

Hi
I have created an iview from a PAR file. In the par file I have a jsp-page with some javascript code. From the javascript coe I want to open a new window with an Excel file.
I have tried window.open("c:
test.xls", "test_window"), but it doesn't seem to work. I have created a small HTML page locally with the same command and there a new window opens with the Excel file.
If I change the local file path with an URL it also works.
Any idea how to open a local file ?
Thanks
/Jakob

Jacob,
I'm not 100% (but 99,9%) and it has to do with security ristrictions of the browser not allowing to have local workstation interation from the web. This is ofcourse very dangerous if the browser would allow it... So therfore it is blocked. What if somone would point to a file/executable that formats your drive so for that reason it is not allowed to have web interaction with a local file. Only with Java Applets this is possible but still with many limitations, and what I remember Google Gears and Adobe Air do have some limited web 2 local file interaction... So best and most simple solution you are left with is pointing to a url instead of a file on a c:\ drive.
PS The reason why it works when you start the html from your local PC has todo with the fact that the browser detects that the html is not running in the web at that moment therefor allowing the access.
Cheers,
Benjamin Houttuin

I want to open an excel file from a folder in the Microsoft live office on Hotmail. Their instruction is to go to tools in Firefox, go to plug-ins and then install Microsofts Office 2010. Can't find plug-h. Help?

I have uploaded an excel file from my desk top to the Windows Live (HOTMAIL?) office suite. When I try to open the file I get an error that says my system is not supported. My system passes all of the listed criteria except for one. That is a plug in from Firefox. The instructions say to go to the Firefox menu, click on tools then plug-ins. Of course when I go to tools plug-ins is not immediately available, but when I do go to plug-ins, I am to click on Microsoft Office 2010. This plug in is supposed to allow earlier versions of office documents to be viewed as well as Office 2010. The plug-in is not available. When I search the Firefox website I am not able to find such a plug-in.
I am using Microsoft XP, Office 2007 and the version of Firefox prior to V4. V4 does not support all of my e-mail clients so am not able to use V4.

I am using Microsoft XP, Office 2007 and the version of Firefox V4 but I have this same problem.

message = "";
viewEnabled = false;
var request:GetObjectByPathRequest = new GetObjectByPathRequest(session);

                                        var oDoc:Document = checkOutFile(doc);
i do not know what method in the CS SDK to open document fom active window and how to map CMIS Document to com.adobe.indesign Document ?

Office 2013 can't open word, excel files from the network after upgrade to 8.1

Hello,
Recently, I upgraded all PCs from WIN 8 to Win 8.1. After the upgrade I noticed that I can't open any word documents and excel files. Before the upgraded I have no problem opened any files. All PCs have over 500GB free space on hard drive. Other PCs that
run Win 7 have no problem open them only the one with Win 8.1. This is what I got:
I right click--> property and there is no unblocked. All files resided on the network server.
Please help.
Jimmy

Hi Jimmy,
Did you get any error message when you try to open an Excel file/Word document?
If so, you can post the error message and event log here.Also ,if you had antivirus software installed, try to disable them to test this issue.
In addition, what happens if you add the network server location as a trusted location?
