How to create a pushbutton delay in the FPGA module in Labview 8.2

I am a very inexperienced programmer of Labview, and I have what I thought would be a simple problem. I have a CompactRIO system that utilizes Labview 8.2 as well as RT and FPGA modules. I am running an end of line tester that uses a pushbutton to start the test. I am looking to force an operator to hold the test start pushbutton for one second before testing begins. If the pushbutton is released before the second is up, the test will not start. In the FPGA module, I cannot figure out how to accomplish this. I have tried using both flat sequence and while loops, but I cannot get the program to work as stated above. With the flat sequence there is not a way, that I could see, to break out of the sequence should the pushbutton be released. Using the while loop, I was closer to a solution, but could not get the program to read the input consistently. I did verify that the 24Vdc signal is getting to the input card whenever the pushbutton is pressed. The program worked fine without trying to add the delay when I was just looking for a transistion to 24Vdc on the input card when the pushbutton was pressed.
Any ideas? Thanks!

Here's how you might do it with a button on-screen in LabVIEW for Windows. If you need more specific help, post your code, or a small portion of it that demonstrates the bit that you can't get working. (The snippet is in LabVIEW 2009 since that's what I'm using, but the attached VI is saved for 8.2)

How to create a record based on the name of a file in the file-system?

Hi,
With a lot of pictures I want to have a database to gather some information about these pictures.
First question is how to generate a record based on a file in the file system?
e.g. the pictures are "c:\fotos\2009\01\disc_001.jpg" to "c:\foto\2009\01\dis_98.jpg" .
now i want to create records with as one of the attributes the name of the picture (not the picture itself). how to create these records (based on the information of the file-ssytem). i.e. the number of records should be the same as the number of pictures.
any suggestions?
any reaction will be appreciated.

You can create a list of files in the directory and read the list files from that directory.

How to create multi garnishment order for the same garnishment document

Hi,
Can anyone tell me how to create multi garnishment order for the same garnishment document. I tried to copy the entry in IT0195 but the sequence field is grayed out so it will just delete the old record. What configuration should I do to make this possible?
Thanks a lot in advance.

hi,
As far as I got it.
You cannot have multiple Garnishment order but if a need arises you have to maintain it in IT216.
For that follow this path goto PA30->pernr->194->change->Garnishment->adjustment.
Since like order you cannot maintain adjustment also directly.

How to create a generalized version of the detailed polygons?

How to create a generalized version of the detailed polygons?
I have a table of detailed polygons (100+ vertices) and I want to get generalized version of these polygons.
For example, assume I have a polygon with 100 vertices. Distance between vertex n and n+1 is 1.0.
I want to get geometry (generalized polygon, line or point) where distance between vertex n and n+1 is 10.0 or more (I want vertices to be considered as one vertex if distance between them is less then 10.0).
Is it possible to create generalized version of polygons on the fly?
Any help is appreciated.
Thanks.

Scenario A:
If all of your polygons have no interaction among them (No polygon shares any boundary with any other ones).
In this case you can use the sdo_util.simplify in 10g to reduce the vertices in your polygons which returns new polygon geometries on the fly.
If you found that simplify is not doing exactly what you want, you can always roll out your own implementation using PL/SQL or the new SDOAPI JGeoemtry class in Java. Both will give you complete access to the coordinate arrays in a polygon and update them back to the database after you have simplified them in your code.
Scenario B:
If your polygons share boundaries, then the above methods will not work since the simplification process may not preserve the topology among your polygons. What you can do then is to use the Java topo package to create a new topology by adding all of your polygons to to an empty topology (which you first create in the database and then load into memory using oracle.spatial.topo.TopoMap). Once you have a topology built in the memory, you can use methods such as oracle.spatial.topo.TopoMap.changeEdgeCoords() to simplify the edges of your polygons. You can then recreate the simplified polygons from the topology. This is just a rough guide; for more details you need to check out the java doc for the various packages mentioned above which are shipped with 10g spatial.

I am wonderfing how to create a temp table in the memory, not in disk?
thanks,

Thanks for rectifying me Howard.
I just read your full article on this too and its very well explained here:
http://www.dizwell.com/prod/node/357
Few lines from your article
It is true, of course, that since Version 8.0 Oracle has provided the ability to create a Keep Pool in the Buffer Cache, which certainly sounds like it can do the job... especially since that word 'keep' is used again. But a keep pool is merely a segregated part of the buffer cache, into which you direct blocks from particular tables (by creating them, or altering them, with the BUFFER POOL KEEP clause). So you can tuck the blocks from such tables out of the way, into their own part of the buffer cache... but that is not the same thing as guaranteeing they'll stay there. If you over-populate the Keep Pool, then its LRU mechanism will kick in and age its contents out just as efficiently as an unsegregated buffer cache would.
Functionally, therefore, there can be no guarantees. The best you can do is create a sufficiently large Keep Pool, and then choose the tables that will use it with care such that they donâ€™t swamp themselves, and start causing each other to age out back to disk.
Thanks and Regards

if input selection is Normal and RDO then only 2 columns w'd be created and the other 2 fixed columns.
Can anybody help me how do I design such report....
Thanks

Hi Developer life,
According to your description that you want to dynamically increase and decrease the numbers of the columns in the table, right?
As Jason A Long mentioned that we can use the matrix to do this and put the year field in the column group, amount fields(Numric values) in the details, add an filter to filter the data base on this column group, but if
the data in the DB not suitable to add to the matrix directly, you can use the unpivot function to turn the column name of year to a single row and then you can add it in the column group.
If there are too many columns in the column group, it will fit the page size automatically and display the extra columns in the next page.

If your still have any problem, please try to provide us more details information, such as the data structure in the DB and the table structure you are currently designing.
Any question, please feel free to let me know.

Hello,
I think you can try two things : the soft reboot, and if it does not work, the hard reboot. Don't worry, you can't lose data with these two reboots.
Soft reboot :
1) Hit the three following keys at the same time :
- Alt
- Right Shift
- Delete
2) wait 2 minutes for the Blackberry to wake up.
Hard reboot :
1) your Blackberry device is on
2) remove the battery and wait for a minute
3) Put the battery back
4) wait 5 minutes for the device to wake up.
Please tell us if it works for you.

How to create a dynamic table were the JTable columns keep varying

How to create a dynamic table were the JTable columns keep varying based on the input to the jtable

Oooh, I lied. DefaultTableModel has an API for adding and
removing columns. I didn't know that. You should have read
the API.
As for preferring to extend AbstractTableModel rather than
DefaultTableModel, I think it's more correct. DefaultTableModel
is a simple implementation of Abstract for basic cases. It isn't
intended to be extended. I figure most people extending
DefaultTableModel are also extending JFrame, JPanel, and Thread
instead of encapsulating the first two and implementing
Runnable for the third.
