• For the complex data type, how to generate the Dll with compatible interface to C/C++

  Hello

  I used the Labview FPGA module to develop test equipment. Now, I need to write a driver that is to be a Dll with compatible interface to C/C++ for this equipment. So that my client who is familiar with C/C++ can call the driver without any study on labview. But I had a few problem on how to convert labview for C/C++ data complex data type. To clearly explain to my question, I have attached a simple example. (see attachment) I try to generate a Dll for the attached example VI and get the the function prototype at the head of the files as below:

  ' void OpenFpgaReference (LStrHandle * RIODevice, TD1 * errorIn, LVRefNum * FPGAVIReferenceOut, TD1 * errorOut).

  As you have known, the type of data "LStrHandle * RIODevice" and "LVRefNum * FPGAVIReferenceOut" Labview data format are. C/C++ do not have this kind of data type and can not reconige it. As a result, I can't call the Dll of C/C++ programming language. How to convert these two data type of labview for the C/C++ compatible data format, and then build the Dll? Anyone know about this?

  The answer is really apprecaited! Thank you in advanced.

  As I found in the following article:

  http://digital.NI.com/public.nsf/WebSearch/FB001AA027C8998386256AAD006C142D?OpenDocument

  LVRefNum is the name of resource of LabVIEW VISA or refnum, and "it is impossible to convert LabVIEW VISA name of resource or refnum VISession valid ID."
  This means that external code modules can not access & control the session VISA which is open by labview. But for my purposes, I will not attempt to access this VISA extenal code(C/C++) session. I just hope that save this session VISA in the external code once I opened it in Labview dll; and pass it to the labview dll when needed. While I have not need to login again when I need to control the device. Is it possible to do?

  A LVRefNum is really just a single int32 value. Its meaning is useless for other environments than those who created it so that you Michael not any what in C/C++ caller but pass it back to other functions in your DLL, but this often isn't a problem at all.

  You can take the following statement of the LabVIEW extcode.h headers and add them to your delabviewed header files to make it work in such a way.

  #define Private (T) typedef struct T # _t {void * p ;} * T}

  Private (LVRefNum);

  The LStrHandle you must set a standard C string instead in your export DLL and document what is the size of the string buffer should have if it is an output parameter.

  TD1 error clusters should also be divided into their parameters (C compatible) separate for all items or just to the left of suite entirely.

• Ksoap2 complex data types

  I'm moving the xml as a parameter in a Web service, however it doesn't seem to work.

  The Web service is a service of .net, the required parameters is a group of data.  It is built in xml that I put in a string and then add it as a parameter to aid,

  SoapObject rpc = new SoapObject(serviceNamespace, _soapAction);rpc.addProperty("paramname", xml);
  

  I have no problem to send the basic parameter types, the type complex seems to be incorrect.  Someone else has managed to use complex data types when communicating with a web service using Ksoap2?

  Use SoapSerializationEnvelope addMapping with namespace, the name of the class (as in the wsdl document) and class (getClass() or .class) itself.

• Consume a web service from ASP which responds with complex data types...

  Here's my problem - I'm trying to consume a web service from a provider that uses complex data types.

  The starting of the WSDL part looks like this (I have not included all) - named have been changed to protect the innocent:

  " < wsdl:definitions targetNamespace = ' http://domain_name ">
  WSDL: < types >
  " < s:schema elementFormDefault ="qualified"targetNamespace =" http://domain_name ">
  < s:element name = "Authentication" >
  < s:complexType >
  < s:sequence >
  < s:element minOccurs = "0" maxOccurs = "1" name = "User name" type = "s:string" / >
  < s:element minOccurs = "0" maxOccurs = "1" name = "Password" type = "s:string" / >
  < s:element minOccurs = "0" maxOccurs = "1" name = "Token" / >
  < / s:sequence >
  < / s:complexType >
  < / s:element >
  < s:element name = "AuthenticateResponse" >
  < s:complexType >
  < s:sequence >
  < s:element minOccurs = "1" maxOccurs = "1" name = "AuthOK" type = "s:int" / >
  < s:element minOccurs = "0" maxOccurs = "1" name = "Token" / >
  < / s:sequence >
  < / s:complexType >
  < / s:element >

  Since it is a return, with a sequence of complexType, I expect an array or a structure returned, but instead I just get the value of "AuthOK" and no way to get something else.

  Here are the ways I tried to call it:

  < cfscript >

  WS = createObject ("WebService", "https://WSDL_URL");

  WS_ret = WS. Authentication (name of user = "username", password = "password", token = "");

  < / cfscript >

  < cfdump var = "" #WS_ret # "/ >"

  < cfinvoke webservice = "WSDL_URL" method = "Authentication" returnVariable = "WS_ret" >

  < name cfinvokeargument = "userID" value = "7253320" / >
  < cfinvokeargument name = "password" value = "ctpjxs3" / >
  < name cfinvokeargument = "SecurityToken" value = "" / > "

  < / cfinvoke >

  < cfdump var = "" #WS_ret # "/ >"

  Any ideas how I can get the other variables in the sequence? I have other calls after that have a greater amount of variables, and as such I can't use without being about to get more than the

• Working with complex data types in web services...

  Hi all
  I have created a Web service and created an interface for this in the ADF. Now that my web service returns a complex data type, I followed the steps in this article "http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html" and it works very well, my results are also displayed. But the only problem is that I get a warning "Houston-25009: cannot create an object of type: java.util.calendar value: 2008-09 - 23 T 23: 51:30.000 + 05:30 ' and if I can replace all the java.util.Date oracle.jbo.domain.Date then I get a warning" Houston-25009: failed to create an object of type: oracle.jbo.domain.Date with the value: 2008-09 - 23 T 23: 51:30.000 + 05:30. Now I am unable to understand this, but I think it's a problem of data type mapping, but do not know how to remedy this.

• Type of input data for the graph waveform

  Waveform graphs do not change the type of input data according to the wire. When I create a new chart that is set to double data type and does not change what I connect to waveform, so I copy graphics to another VI for appropriate indication. But the graphics don't accept complex data. How can I change the type of input data?

  The graphics in vi you have posted behave properly on my machine.

  Change according to the type of data that connect you to them.

  Maybe something wrong with your installation?

• Creation of complex data signals

  Hello

  I have 2-channel audio that contains the parts real and complex of an I / Q wave. I'm trying this demodulation using block MSK modulation toolkit, but I have trouble accessing the i / Q stream in the right type. The MSK block requires a complex waveform input, but after the construction of this waveform complex, I discovered that he really had to a 'Waveform.ctl of complex data.

  How can I get my data in the right format? I can't find a block which generates this 'Waveform.ctl complex data.

  I have attached a picture of the situation.

  Best regards

  Jan

  Try this

  Right-click on the entry of complex waveform of this Subvi node MT demodulate MSK. Click on 'Create' > 'Constant '. Now remove the wire between the newly created constant and the Subvi. Adds a set of cluster name. Wire the constant in the top of the boot of cluster name. Left click and pull on the bottom of the boot of cluster name until 3 entries appear. Click with the right button on each entry and use the item select to get the entries you need.

• How to record a little complex data in json?

  Hi all

  I want to use json to store complex data a bit. I checked the sample application code. It's too simple.

  The data are as follows:

  {

  'day': 'ddd ',.

  'type': 'xxx ',.

  'name': "qqq"

  "amandine":]

  {'name': 'sss', 'set': 'ddd', 'time': 'ddd'},

  {'name': 'eee', 'set': 'fff', 'time': 'fff'},

  {'name': 'qqq', 'set': 'ggg', 'time': 'ggg'},

  {'name': 'aaa', 'set': 'vvv', 'time': 'vvv'},

  {'name': 'zzz', 'set': 'ccc', 'time': "ccc"}

  ]

  }

  I am confused with QVaraintMap, QVariantList and QVariant and don't know how to use them properly.

  PS: I'm new to json. I used to use MySQL in my work.

  Thank you.

  brad_qqq

  The simplest approach is the following:

  JSON object (something wrapped in {}) will be a QVariantMap

  List of JSON (something wrapped in []) will be a QVariantList

  Everything else (numbers, strings, boolean, etc.) will be a QVariant

  Everything will be a QVariant when initially mapped out, and you must check the types with canConvert (Type) and use the methods toXXXX, that all return values (http://qt-project.org/doc/qt-4.8/qvariant.html) to get the respective types and use the data.

• Vista will not display description of the file on mouse over. File name, Type, size, and Date modified see the upward, but no description.

  Vista will not display description of the file on mouse over. When I mouse over, a pop-up window displays showing: file name, Type, size and Date of change, however, it does not show the description of the file.

  So, for example if I have 5 files on different types of screw - the description tells me that the size of the screws. IE. 1.5 mm or 1. 8 mm.

  Update: try to get the description of the file displayed messing around in the file properties, now out of 10 records, only 2 includes the name of the file in the mice on the pop-up window. So now what lack us, it's the file name and the Description file.

• convert the varchar2 data type to the data number type

  How to convert the varchar2 data type to the data type number.
  
  
  It looks like my data
  
  create table one)
  col1 varchar2 (50)
  col2 varchar2 (500);
  
  Insert in a (col1, col2) values ('1234 ', ' 2345');

  I need to create a table with the same columns with data like number types (19)
  
  can someone help me
  
  Thank you

  You have changed your original post, so now I see that you get the invalid number.

  This is why you should always avoid the varchar columns to store numbers or dates...

  Since your table source contains a nonnumeric value, you can write a pl/sql to convert data and see what records are false:

  SQL> insert into a (col1,col2) values ('xxxx','2345');
  
  1 row created.
  
  SQL> select * from a;
  
  COL1     COL2
  -------- --------
  1234     2345
  xxxx     2345
  
  2 rows selected.
  
  SQL> create table b (col1 number(19), col2 number(19));
  
  Table created.
  
  SQL> set serverout on
  
  SQL> declare
    2  cursor c is
    3  select * from a;
    4  begin
    5    for r in c loop
    6     begin
    7       insert into b values (to_number(r.col1), to_number(r.col2));
    8     exception
    9       when invalid_number then
   10        dbms_output.put_line('Row rejected: col1='||r.col1||' col2='||r.col2);
   11     end;
   12    end loop;
   13  end;
   14  /
  Row rejected: col1=xxxx col2=2345
  
  PL/SQL procedure successfully completed.
  
  SQL> select * from b;
  
        COL1       COL2

• Confusion of Data Type of logical data model.

  I don't understand.
  
  When you define a logic model, I want to assign the data types for the attributes in my model.
  I understand a logical data type such as money, and that a logical data type may be implemented differently in different databases. The concept makes perfect sense to me.
  
  Choose a data type for the logical types.
  
  It ignores the logical data type that I have picked and put in another type of places data. I'm guessing it's a physical mapping. I understand the logic-relational mapper does this, but I don't understand what is happening right now in the life cycle of the model.
  
  Let's say that I take money. He puts in the logical data type Double, no money.
  If I take a Date or DateTime, it puts the Date in the logical data type, then what's the point of giving me two types to choose?
  
  Seems a little wonky.

  Type of logic is still there, made in the dialog box is not correct. Logic type is transferred to the relational model and despite his record native type on the diagram it is still there and you can change the mapping of different native type later.

• Types of cube data

  I'm in the middle of implementing a 10 g environment, using AWM, which I expected Import Express in olap data.
  
  I have a couple of cubes that have different types of boolean data, shortinteger, brief, and text.
  
  Now, I'm pretty cool creation AWM and cube, and I've read a bit of documentation.
  
  When I go to create a new cube, I noticed that I had only three digital options for the data type. either NUMBER DECIMAL and INTEGER
  
  So far for blocks of text: I unselect all dimensions for the rarity and use no compression, all by selecting not additive in the rules tab for all the dimesnsions. When I go to create the measure I can select text.
  
  I just want to know how to make short data cubes and shortinteger of type boolean? Also, is it read all documentation relating to data types?

  Hello

  It is not possible to define a cube in AWM 10 g using a boolean data type, short or shortinteger - these are the old native Express datatypes and although they still exist in the OLAP engine, the GUI is not available.

  You need to use INTEGER to boolean (1 or 0) and shortinteger and DECIMALS for short - in each case need you more storage space to store the database, but the compression algorithm should allow you to use a lot less overall storage.

  In your case, I would not recommend that you use NUMBER this will reserve enough space for numbers with 38 significant digits that would be excessive for your needs (DECIMAL's 15 p.c.).

  I think that the only documentation on this subject is in AWM help

  In 11g OLAP, you can specify scale and precision for the type of data NUMBER giving you as much control as you want.

  I hope this helps.

• FIFO of RT with complex data?

  Scenario:

  We have a deterministic loop on a target RT (OR PXI)-. The need for speed at 1 Hz only with as less as possible jitter. This deterministic loop will execute measures picoAmp with many units of Keithley6487 (using low-level SCPI works, so all control configuration of measurement devices, then "INIT" (takes about 2 msec per unit) and approximately 300 msec later "fetch" data from the Keithleys (requires approximately 10 msec per device).) This deterministic loop will be a state machine and accept orders from lower priority loops (as zero check, reset, etc. a Keithley or multiple). The measured data will be in the form of double table, so it's OK for the communication between the RT FIFO loops.

  However I am wondering how to extend the functionality: measurments a warning might be created by Keithley screw as a string. In addition, an acknowledgement of receipt/feedback some actions performed on the Keithley should be reported to low priority loops again in original form they are strings. The chains are not supported by RT FIFOs, but I found this tip below how convert it (see below).

  In order to disseminate all the information correctly, I think that I should send it measure in the form of a double array data, and an array of strings size even that would hold all related SCPI in guard/acknowledgements of Keithley units. Since I can't use cluster either to RT FIFO, y at - it something to 'compress' or convert the type of cluster complex into something RT FIFO compatible?

  Right now I think just a workaround solution: I could create two RT-FIFO, double for the data table, and the other using the trick below to convert string (all two fixed sizes). I could convert the array of strings of information Keithley in a single string delimited by commas, I can use the function 'String into byte array'.

  All tips and suggestions are very welcomed!

  WARNING: I am a beginner in the field of the RT...

  

  During the initialization of the RT-FIFO instead of using an array of fixed size, use any format you need for your data, but before you pass it to the function "Create FIFO", use the "Create new DVR" and what reading use the "Destroy DVR" feature to pick up your package of data of arbitrary length.
