How can I use an Access front end and Access button to control a LabView Shared variable boolean?

My company has invested a lot of money on the office network to write many many access databases and front ends. I'm looking for a way to tie a button on an access front end to toggle a LabView boolean shared variable to notify me when they changed something on their side of the network. I'm not seeing anything that helps on a web or forum search. They don't like the idea of a separate labview control that they have to push a button on to let me know.
Thanks

Hi Patrick,
While this is not the intended purpose of Network-Published Shared Variables, you might be able to accomplish this by writing separate accessor VIs for reading from and writing to the variable, making sure to wire the inputs and outputs. Then, you could build a DLL, making sure that you include the accessor VIs as Exported VIs and include the DLL Library in the Always Included section of the DLL Build Specifications. During this process, you will define the function prototype, which will provide the function call, required parameters, and return values. Once the DLL is created, you can then call it and its functions from another programming language (C, C++, C#, VB, etc.). This may or may not work, but it is the only way that I can think of at this point. I have included some references that may help you in this process.

Hi,
I have attached here an example of doing the same using shift registers and local variables. Take a look. Shift register is always a better option than local variables.

How can I use LCCS with ActionScript 3 and Flash CS4?

Hi,
Using Stratus I was able to create an an application using Action Script 3 and Flash CS4. The sample code on the Adobe site was quite straight forward and easy to understand. I now want to switch over to LCCS but can't find anything any where on how to use Action Script 3 and Flash CS4 with LCCS. Do I need to know Flex to be able to use LCCS? Everything was quite simple and easy to understand with Stratus and makes complete sense. But LCCS is really confusing. Is there any sample code on how to establish a connection in Action Script 3 and then stream from a webcam to a client. There is nothing in the LCCS SDK that covers Flash and Action Script 3. Please help! I found the link below on some forum but it takes me nowhere.

Hi,
Welcome to the LCCS world.
Please refer to the SDK's sampleApps folder. There would be an app called FlashUserList. The app demonstrates how LCCS can be used with Flash CS4. Its a pretty basic app, but should help you moving.
We are trying to improve our efforts to help developers in understanding our samples. Please do let us know if we can add something that would help others.
Thanks

If you absolutely must have the Microsoft applications, you can purchase and download them from http://microsoft.com/mac.
Free software suites LibreOffice and OpenOffice offer similar functionality (word processing and spreadsheets).
Or you could do worse than look at Apple's Pages, Numbers and Keynote, which should already be installed in your Mac and can export to Microsoft formats if need be.

Hi,
How can we Hide / Disable the Help(?) and Close(x) buttons which are located in the right corner of the Top Link Bar in the Sharepoint Document Library pages as well as Excel Web Access?

Hi,
In the xlviewer.aspx, we can find the two buttons like this:
To hide them, you need to add the CSS into the xlviewer.aspx which stays in:

Can you use the native GTK Forward and Back buttons instead of the default ones?

Hello!
On old versions of Firefox, the default theme always used the native GTK forward and back buttons. Ever since I updated Firefox, it overwrites these with its own arrow. Does anyone happen to know off the top of their head if it's reversible?

It looks like the GTK theme was not updated to support versions of Firefox after version 29. Have you contacted the developer about this as well?
Looking for a hack you may find more answers in mozillazine.org.

Advice regarding using 3.5 front end AND 7.0 front end on users' machines

Hello everyone,
We are trying to determine the best way to roll out the new 7.0 front end tools. We are doing a technical upgrade to 2004s first, and later converting all the objects. Initially we plan to have both the 3.5 and 7.0 front end tools both residing on users' pcs, until we convert all objects to 04s.
Does anyone have a recommendation for rolling out the new tools to users, with out the risk of having them accidentally convert objects when they open queries (we have been told that if you open a query in the new tools, it automatically converts the objects). We need to prevent this from happening until we are ready to convert all the objects.
Thanks in advance for any advice!

The most important thing is to use naming conventions (maybe a new naming convention using the new tools). Then set security up to prevent conversion depending on your scenarios. When migrating, it is recommended to be very careful around converting global elements (variables, Global Calculated Key Figures, and Global Restricted Key Figures). Within the RSZCOMPDIR table, there is a version field (greater than 100 is 2004s elements) so you can see the version there as well. It is recommended to migrate all queries within a single infoprovider together to avoid conflicts with global elements.

How can I store movies in the cloud and access them from my devices?

Hello,
I would like to store movies in the cloud and access them from my device without having to download them to the device because there is not enough space on the harddrive to store them on it.

Unfortunately I don't use sugarsync myself, I have a dropbox account and it works slightly differently.
As I understand it you can upload files to a folder in sugarsync from your computer without having them sync to any of your devices. You can access that folder from any of your devices, and although you would need to download them in order to play the video file, you could then delete them without deleting the files in the sugarsync folder in the cloud.

How can I use an IF ELSE statement and the xdoxslt: get_variable together?

First of all, I'm a big fan of this forum and I just want to thank the community for helping make the BI Publisher world a better place.
I'm trying to populate a table with a years worth of data with the column=PRODUCT and row=month of DATE. Here's the catch, not all of the months will have data. So here's where my problem is, I'm not able to use an IF ELSE statement along with a XDOXSLT:GET_VARIABLE expression so that if there's no data for that month the default value will be 0.
Can someone help me find a solution to either one of the attempts below or a completely new method? Thanks!
BP4 = numeric month value using DATE (more code to pull only month from DATE not included here)
JAN1 = PRICE if data exists, else 0
1) I tried this and it didn't work:
<?if: xdoxslt:get_variable($_XDOCTX,'BP4'),01 then xdoxslt:set_variable($_XDOCTX, 'JAN1',PRICE) else xdoxslt:set_variable($_XDOCTX, 'JAN1',0) end if?>
<?xdoxslt:get_variable($_XDOCTX,'JAN1')?>
<?end if?>
2) I tried this and it didn't work:
<?xdoxslt:ifelse(xdoxslt:get_variable($_XDOCTX,'BP4')='01',xdoxslt:set_variable($_XDOCTX, 'JAN1',PRICE),xdoxslt:set_variable($_XDOCTX, 'JAN1',0))?>
<?xdoxslt:get_variable($_XDOCTX,'JAN1')?>
<?end if?>
3) I tried this and it didn't work:
<?xdofx:if xdoxslt:get_variable($_XDOCTX,'BP4')='01' then xdoxslt:set_variable($_XDOCTX, 'JAN1',PRICE) else xdoxslt:set_variable($_XDOCTX, 'JAN1',0) end if?>
<?xdoxslt:get_variable($_XDOCTX,'JAN1')?>
<?end if?>

<PRODUCT>BPD</PRODUCT>
</ROW>

Edited by: 990965 on Feb 28, 2013 8:27 AM

let me clarify my logic, the template 1) searches for the relevant PRODUCT (in the case below, it searches for BPD which is the column in the table) 2) searches for the relevant month in DATE (which is the row in the table) 3) if data exists, get PRICE else default to 0
Variable definitions:
BP4 = numeric month value from DATE (more code to get this value not included here, but it works...)
JAN1 = set to PRICE if data exists for that month, else 0
the query is only pulling all of the existing data, so if there's no data for March then there wouldn't be a March entry in the xml. In the sample xml below, we only have data for the first two months (Jan, Feb) so that's the only data in the xml. I can't check if PRICE is null because the xml will not have any data for March.
I've read through other threads and it seems that BI Publisher can't use an IF THEN ELSE with the XDOXSLT:GET_VARIABLE. I sent the template and xml to you.
Sample XML:
<ROW>
<Name>Craig Hernandez</NAME>
<DATE>2013-01-01T00:00:00.000+08:00</DATE>

There is good news coming!
Technology experts are working on a movie storage system where YOU have physical possession of the movie.
This system stores the movie digitally on an optical disk system that will not be dependent upon a congested, complicated, and fragile network.
Because all of the data is stored only a few feet from your television, all the bottlenecks are removed. Performance and reliability are virtually flawless.
Further, the system will not utilize any form of security codes, authentications, or passwords. Once the optical disc is purchased it can be moved around freely at will, and can even be lent or given to friends and neighbors with zero hassles.

How can we use the table partitions feature and.........

Hai friends when i tried to use the bitmap indexes and table partitions feature ,
I got a message like this
'table partiotion feature not enabled'
so please tell me how can i enable those features so that i will be able to use those features..........

Partitioning and Bitmap Indexes are features of Oracle Enterprise addition. In fact, I think that Partitioning is an extra option that needs to purchased with Oracle Enterprise - it is not a default feature.
These features do not exist on Oracle Standard Edition (and likely Express Edition too).

How can I use Time Capsule for backups and an external hard drive?

I have a large file/program on my iMacs hard drive that is 62GB and I would like to keep only things I need on my iMac. I have a 2tb time capsule currently used for backing up. It has roughly 1.66 TB free. How can I move the 62GB program onto my Time Capsule and still use it for backups? Also, is this stable? And don't worry about backing the program up because it came on 8DVD discs.
Thanks.

1. Mount the Time Capsule as a drive and drag the application over to it. If the application requires system components, those won't be transferred; if those are only data files, you may be able to drag them over as well and then create a symlink or alias to a folder enclosing their current location.
2. The application may work slowly if this is done. Note that Time Machine will eventually use up all the free space on the Time Capsule that isn't reserved by being allocated to a disk image.
