How to get string (specified by line and column) from txt file with labview

Hi everyone
How to get string (specified by line and column) from txt file with labview
thx
Solved!
Go to Solution.

As far as I know, a text file has no columns. Please be more specific. Do you mean something like the 5th word on line 4, where words are separated by a space, and lines are separated by a newline character? You could the Read from Spreadsheet String function and set the delimiter to a space. This will produce a 2D array of strings. Then use index array and give the line number and column number.

How to access specific control event in other component

Hi to all friends out there.
I have created few components in which i am doing comunication through events. But my problem is that for achieving this i have to make event bubble and than add listner to where i want to use.As event it bubble and same ype of event is bubled by other compononents.
So please tell me how i fillter specific event to that componet where i am adding eventlistener.
Thank you in advance.

If you want specific rows, you can always load the values from the ResultSet into a Map and access them that way. You shouldn't be noodling around with a ResultSet that way - it's a database cursor, not a substitute for a data structure.
If you really need just a few rows, you'd be better off writing a narrower query to get just what you need. Bringing back 1,000 rows for the sake of accessing a handful is a waste.

How can I create a scene and move 3D models in INSIGHT with Labview?

Hi!
I need some help in doing a LabView application. What i have to do is controlling a 3D model represented in Insight with Labview. Something similar like the six-axis-robot example. I follow the insight configuration wizard, but nothing moves. Comparing the ".cis" files in my program and the one from the six-axis-robot, i found that in the six-axis-robot file contains something called localsystem and the one made by me, doesn't. Can be this the problem? How can I make it work? I would need some kind of step-by-step response, because i'am a beginner with Insight and 3D models. Thanks in advance!
Regards!
Juan

Thanks for the advice!
I'm actually finding the next problem. Although in my VRML file the objects are defined separately in a jerarchy tree, I can't move(rotate, translate) each object individually. I have noticed that when i define a new local system and asign it the points of the object i want move in the way you explain (right click, and then dragging the points to the new local axis), the movement of this object is dependent of the other local systems i have defined for other objects , specially if the slave nodes of the .cis file has a lower numeration than the object i want to move. The fact is, the movements assigned , for example to the nodes 1 to 100, will affect to the rest of the nodes if i also define for the rest of the nodes other movements. How can i solve this? I send you my .cis file, just in case my explanation is not enough clear. In this file you can see that movements assigned to nodes 1 to 4078, will also affect to nodes 4079 to 7168, and what i would like to do is define a movement for each obeject independently.
Thanks again!

How can i control the I2C bus with Labview

Hi
How can i control the k8000 from http://www.velleman.be ( I2C bus) with
Labview.
all info is welcome.
[email protected]

if you are using Linux (and the Linux version of LabVIE W) it should be
fairly easy to use the lm_sensors ( http://www.netroedge.com/~lm78/ )
libraries and source code to control a device connected to a PC's I2C bus.
Go here http://www.netroedge.com/~lm78/hardhack.html to see how to tap into
the I2C bus of your PC. You may be able to apply info here to roll-your-own
on a MS Windows 98 / 2000 OS.

hi all,
i am saving all the hr tables in a internal table.
say, mtable = 'pa0002' is the content of mtable on looping above internal table.
LOOP AT i_itf_list INTO wa_list. "wa_list contains list of hr tables.
   mtable = wa_list-tabname.
   LOOP AT persno. "persno contains list of personal numbers.
"how to acess particular row of (mtable) dynamically where pernr = persno-pernr."

thanks.

Hi,
Use below code for your reference.
data : ref_table_des type ref to cl_abap_structdescr,
          dref type ref to data.
field-symbols : <itab> type standard table,
                        <wtab> type any.
data : mtable type tabname.
LOOP AT i_itf_list INTO wa_list. "wa_list contains list of hr tables.
clear mtable.
mtable = wa_list-tabname.
LOOP AT persno. "persno contains list of personal numbers.
ref_table_des ?= cl_abap_typedescr=>describe_by_name( mtable ).
create data dref type handle ref_table_des.
assign dref->* to <wtab>.
create data dref like standard table of <wtab>.
assign dref->* to <itab>.
***if you want to select multople rows use below select***********
select * from (mtable)
into table <itab>
where pernr = persno-pernr.
********if you want to select single row use below select************

How to access document properties/attributes?

Hi folks,
I have a document with some properties (File->Form properties) like title, author, description and so on. Now I've read that I can use the xfa.form.form1.desc.title method to access the title. But the only value I get back is [object XFAObject] .. what is this? It's the same with author or description.
Anyone who can help here?
Thx alot,
Tobias

You need to get the object's value property. So,
xfa.form.form1.desc.title.value;

How do I get a downloaded ring tone to work Droid MAx with KitKAt?

I downloaded a ring tone but since it is on the SD card I cannot do anything with it except play it in a music player. It is not available as a ring tone and I cannot move it to the ring tone folder. Any ideas?

jcrummie1,
Ringtones are a great way to personalize your device and we are here to help make sure we get it set up immediately.
What happens if you go to the ringtone in the music player and press and hold down on the ringtone? Do you see an option to set as? If so, select that option and select to set it as a ringtone/notification. Let us know if this helps? Was the ringtone originally purchased online or over the phone?

How to control a parallel port with labview

Hi. I'm trying to control a dc motor with a parallel port using labview. the program has to be able to vary the out put voltage of the computer (0 - 5V) through the parallel port into a circuit which will step up the voltage for the motor. Any help would be greatly appreicated. garreth

Do you want to output and varying signal from the parallel port pins? If so you can't do it, the port pins are digital and can only be high or low, not inbetween. You can control the individual lines high or low using the In/Out Port vis in Advanced>>Port I/O. For more help on doing this search the message archives (I know I've answered a few) and NI's site, there is some good info on it out there. Try some of these for starters:

How can i control the Tektronix AFG3022 with LabView 7.0

I am trying to control the Tektronix AFG3022 Function Generator with LabView 7.0. Is there a premade program I can download and use?

If it is not in 7.0 make new thread and ask nice if someone can convert to labview 7.0.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

How can i control a sensor CNY70 with labview?

i am taking a mechatronics course and they ask me as homework to control a sensor but i don not understando what can i control from this sensor, i expect you could help me

i would start with working out the system, datasheets on the cny70, work out exactly what is required from the question. spec out the hardware, then start writing out rough ideas. Keep looking back at the question and it will all slowly make sense. I wouldnt dive straight into coding until i understand exactly what i need to be trying to achieve.
once you understand exactly what you need to achieve and with what hardware you can look into planning the code and taking it from there. If you get stuck with coding feel free to ask for help and post the code you have as most people on here will heppily pass contructive critisism as well as help you through the parts your struggling with

How to chane camera attributes

Hello all, I need to modify i real time some camera attributes ( Exposure time, Gain, etc.) but with the function IMAQdxSetAttribute is it not possible, and cause an error, (attributes like zoom, focus, I don`t have any problem).
It is possible to change this attributes with other function ???
thanks for all.

Access to class-attribute by Interface-reference

Hi OO-Gurus,
I use an implementation of BADI ME_PROCESS_REQ_CUST to fill and handle user-defined fields in the MM-Purchase-Requisition, method IF_EX_ME_PROCESS_REQ_CUST~OPEN.
There I use a reference variable which refers to an interface (type ref to IF_PURCHASE_REQUISITION_ITEM) to access the item-object. My problem is that I need to have access to the class-attribute my_state. The corresponding class lcl_req_item is defined locally (LMEREQF01). So I cant use a reference variable with reference to this class (so widening cast using the interface-reference is not possible) .. Does anyone know a trick how to access the class-attribute anyway?
Coding:
data: l_item_list       TYPE MMPUR_REQUISITION_ITEMS,
           l_item             TYPE MMPUR_REQUISITION_ITEM,
           l_item_akt       TYPE mereq_item,
           l_item_ref        TYPE ref to IF_PURCHASE_REQUISITION_ITEM.
l_item_list = im_header->get_items().
loop at l_item_list into l_item.
    l_item_akt = l_item-item->get_data( ).
    l_item_ref = l_item-item.
endloop.
(Debugging the code, I manage by doubleclicking the fieldcontent of l_item_ref (e.g ) to show the content of the class-attribute my_state. This works only if the field Interface in the Debugger is empty because then I see the attributes of the class. If the field Interface is filled with IF_PURCHASE_REQUISITION_ITEM, there arent any attributes shown.)
Thanks in advance for your kind help!!

The following sample coding shows you how to solve your problem. Please do not ask me how I came across this solution.

l_item_list = im_header->get_items( ).
LOOP AT l_item_list INTO l_item.
    l_item_akt = l_item-item->get_data( ).
    l_item_ref = l_item-item.
    lo_obj     ?= l_item-item. " casting to root object !!!!!
    ld_attr = 'MY_STATE'.

    ld_attr = 'MY_STATE->ITEM'.
    ASSIGN lo_obj->(ld_attr) TO <ls_item>.
"    ASSIGN l_item_ref->(ld_attr) TO <ls_item>. " does not work...
    ld_attr = 'MY_STATE->ITEMX'.
    ASSIGN lo_obj->(ld_attr) TO <ls_itemx>.

Error accessing constnt public attribute of a class in an overwrite method.

Hi Gurus,
I am facing an error while accessing a constant public attribute while using it in the overwrite-exit of a methods.
The constant which is declared as public in the attribute section of the class is not available in the overwrite-exit of the method.
Please suggest me how to access the public attributes in the overwtire exits of the methods.
Thanks.

Hi Ramneek,
Let me explain you the entire scenario:
Actually we are trying to ehance the SAP standard class : CL_FITV_POWL_FEEDER_TRIPS in ECC 6.0 EHP 5 .
We tried to create and overwrite-exit of the method "IF_POWL_FEEDER~GET_ACTIONS".
Overwrite-exit of a method is just like a method which will be called instead of the standard method : IF_POWL_FEEDER~GET_ACTIONS.
But the problem which we are facing here is that the Attributes which are defined in the class CL_FITV_POWL_FEEDER_TRIPS, are getting accessed from the overwrite-exit method.
Becuase of this we are not able to implement our custom logic.
