• 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.

• Boolean converter doesn't work is not for the string data type

  Hi gurus,

  I am creating a Boolean converter based on the O/N value for column EO, but every time I select the checkbox that's throwing error "attribute with the value false precision/scale not valid."

  If I add PrecisionRule = 'false' for TestFlag to the EO, I had ORA-12899: value too large for column 'XX '. "" "" FDY_TEST '. "" TEST_FLAG' (real:, maximum of 5: 1).

  Seems that it is still store 'true' / 'false' char to instead "Y/N", even if the POS in the converter class return System.out.println ("getAsObject - value is Y")

  If I use the transitional attribute (TestFlagDummy) and change the EOImpl to TestFlagDummy getter and setter, it works very well.

  I was wondering why the converted does not, in which case the other converter for string I test to convert the value entered for upper case works very well.

  Appreciate any help.

  Hello

  "The number of heartbeat for the host data warehouses is 0, which is less than required: 2".

  I search the Web and there are similar problems when people has only a single data store (the one that came with ESXi) and need to add another but in my case... vcenter detects any...

  In the views of storage I see the store of data (VMFS) but for some strange reason the cluster not

  In order to achieve data warehouses minimum (2) can I create an NFS and map it in THE 3 esxi hosts? Vcenter which consider a play config?

  Thank you

  You probably only have local data warehouses, which are not that HA would require for this feature (pulsations datastore) to work properly.

  You will need either 2 iSCSI, FC 2 or 2 NFS volumes... Or a combination of the any of them, for this feature to work. If you don't want to use this feature, you can also turn it off:

  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
  -------- --------

  xxxx     2345
  
  2 rows selected.
  
  SQL> create table b (col1 number(19), col2 number(19));

  SQL> set serverout on
  
  SQL> declare

    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));

• Table of functions and direct requests for NUMBER data types database

  Hello. I call a number of functions table of our Enterprise BI server, and I chose to do this by using direct database requests (I believe you can also call functions table in the physical layer of the repository, but is not what I do). The problem is that whenever I go back any number of the table function which is not a whole number (1.23, for example), BI assigns the INTEGER data type to the field rather than the data type DOUBLE, rounded so my number to the nearest integer. Here is a short example:
  
  Create these 3 database objects:
  
  CREATE or REPLACE TYPE my_row AS OBJECT (my_num NUMBER);
  
  CREATE or REPLACE TYPE my_tab AS TABLE OF THE my_row;
  
  FUNCTION to CREATE or REPLACE my_table_function RETURN my_tab
  PIPELINED IS
  BEGIN
  PIPE ROW (my_row (1.23));
  END;
  /
  
  
  Make this your request at your request Direct to database:
  
  SELECT my_num FROM table (my_table_function);
  
  
  This query returns correctly '1.23' when it is called from the database. In BI, on the other hand, it returns a value of '1' (and the field of labels an INTEGER rather than data type DOUBLE). If at the request of data Direct you change column properties-> data-> decimal from 0 to 2 Format, then it displays is not surprising "1.00". I then tried to change MY_ROW. Data type of MY_NUM by explicitly specifying the precision and no luck. BI still labels this field as an INTEGER. Then I started to try to deceive BI massaging the SQL statement itself. None of the following worked:
  
  SELECT to_number (my_num) as my_num2 FROM table (my_table_function);
  SELECT my_num2 + 0.01 as my_num3 FROM (SELECT my_num - 0.01 AS my_num2 FROM table (my_table_function));
  SELECT to_number (to_char (my_num)) as my_num2 FROM table (my_table_function);
  SELECT to_number (substr (to_char ('x' | my_num), 2)) as my_num2 FROM table (my_table_function);
  
  Now, I found a solution, but I'm surprised that I have to resort to that:
  
  SELECT * FROM (SELECT / * + NO_MERGE * / table my_num (my_table_function));
  
  Is anyone out there knows a better way to do it? The above is a hack in my opinion. :)
  
  Thanks in advance for any input.
  
  -Jim

  Yes, it's really amazing.
  But I got it.

  CREATE OR REPLACE TYPE my_row AS OBJECT (my_num NUMBER(10,2));
  

  and in your SQL:

  SELECT cast(my_num as double precision) as my_num2 FROM table(my_table_function);
  

  I have the good result and I see the numbers after the decimal point.
  Very delicate!

  Hi all

             1

   PLOT_NUMBER PLOT_NAME       PLOT_NUMBER
  ------------ --------------- ------------
             1 hill park       1
             5 seawods         5

  as you can see here this number of parcel 2, 4, and plot_number 3.6 not reported because they are string.
  
  Can anyone please suggest what can do us in this case.
  
  I can't do chane data type.
  
  Thanks in advance

  What you can do in the case?

  Drop table table_b purge

  as the 'design' of this table is obviously out of whack, and the content should have been

  PLOT_NAME       PLOT_NUMBER
  --------------- ------------
  seawods         5
  bridge cros     2
  bridge cros     4
  hill park       1
  bash hunk       3
  bash hunk       6
  

  You now have the instr function to the "join".
  I would recommend standardization of the design. NOW

• DLL for LabWindows/CVI 8.0 with the bool data type

  Hello

  I want to use a new SWIR camera in LabWindows/CVI 8.0 (Windows XP 32bits).

  The company delivered with the camera produced a 32-bit dll by using Microsoft Visual C++ 2010. The .dll and .lib and .h files include a working SDK/API (some functions with the bool data type)

  Compilation-online syntax error, variable Boolean is not a data type in LabWindows/CVI 8.0

  Generate the import of DLL-online syntax error library

  I tried to convert bool char (typedef unsigned char bool => no more syntax error but the functions does not work.)

  What can I do?

  Martin

  Hello again, Naumann!

  Microsoft Visual C++ 2010 represents Boolean using 1 byte, as stated by MSDN: https://msdn.microsoft.com/en-us/library/tf4dy80a(v=vs.100).aspx

  I guess that you import C++ functions using the syntax for extern "C". Otherwise, because of the C++ name mangling wouldn't you able to bind C++ library against your code CVI.

  You can also specify how you import C++ functions?

  In addition, because you have not described the problem as a corruption of heads or runtime error, I guess the C++ library function is called correctly the CVI. That said, I tend to believe that the problem is not really in the mechanism of interaction of C/C++, but in the C++ library. If you would start calling a dummy C++ function returning an integer from a simple CVI application that should work, because redefine bool in CVI 1 byte must ensure that settings are correctly transferred onto the stack.

  If you need to create a wrapper function of C++ that is not using bool and calls the C++ function, I expect to return the same result.

  Maybe you are missing a few prior initialization steps required? The provider of the camera also comes all example code?

  Best regards!

  Don't be stupid.

  If you do not want to use BLOBs then, or you can use the ordimage.

  It uses ordsys.ordsource for the storage of the image data type. This is a user defined Type of data in advance and has a property called LocalData that stores the actual image. And what is its data type? BLOB OBJECT.
