You don't. This is the callback protoype that would be passed as parameter to another API and as such never will be called by the caller of that API but instead be provided by that caller!
And LabVIEW does not support function pointers at all, so you really can't do this.
The only solution is to write a wrapper function in your DLL or in a separate DLL that translates between this interface and some more event oriented LabVIEW functionality such as user events, but unless you do know C to a fairly good level, you should probably leave that to someone else.

How to call the DLL writing in Vb6.0 from testsatnd?

Hi,
I want to call a dll writting in VB6.0 from teststand. But as i see from the "Step Setting" in teststand, only the C/C++ Dll can be selected in the "adapter" type. I try to use this one as my adapter to call my VB6.0 dll, in result, there is no function can be seen in the "function" tab in teststand.Anyone know how to call the DLL writing in Vb6.0?
Solved!
Go to Solution.

Hi Ivan,
Just to be sure that your DLL is not wrong
you have check if all functions are well and present.
There is tool called "Dependency Walker" You can download it at http://dependencywalker.com/ .
With it you can look "inside" your dll
If you will see your functions there, you will see them (in my case !!always!!) in TestStand, too.
Hope this helps
Greetings

EXP
6 rows selected.
so, the same out put i need to get it in a report.
Thanks

Thanks for ur suggestions.
i have 2 select statements.1st query is the main query for the report.so i used it at the time of report created with datablock.
now my 2nd query is
select letter_content
from ( select content_seq,
     content || case content_seq
when 2 then
' ' || lead(content) over (partition by letter_id order by content_seq)
end as letter_content
from exp_letter_contents
     where letter_id = 103)
where content_seq <> 3;
i had taken 2parameters 1 for the main query and 2nd is for the above query(parameter is letter_id).
now i have to write the above select statement in the report.
so i had taken a field object in the report and then i had written this code in before report trigger.
function letter_contentFormatTrigger return boolean is
begin
select letter_content
from ( select content_seq,
                    content ||
                    case content_seq when 2 then
                         ' ' || lead(content) over (partition by letter_id order by content_seq)
                    end as letter_content
          from exp_letter_contents
          where letter_id = 103)
where content_seq <> 3;
return (letter_content);
end;
when i tried to compile it.i got an error as follows :
error 103 at line6,column 5
encountered the symbol "CASE" when expecting one of the following:
(- + mod null <an identifier>
<a double-quoted delimited-identifier><a bind variable> avg...etc
so,where can i write this select statement.
i am using oracle reports6i

How to call a dll which has one VISA name as input

Hi there,
The Labview application builder can generate a dll file from a vi which is a simple serial comunication program using VISA name as one control.
The problem is how to call the dll file in Labview which has a VISA name as INPUT?
Thanks!
George

I would suggest modifying the LabVIEW VI so that the input is a string control instead of a visa control. The LabVIEW application will work the same and there is no need for any casting. All visa VIs can take a string as an input. Then when you recreate the dll make the input a string. Then you can easily pass a string to the dll from any API.

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...
EXCEPTIONS......
The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:

How to call a dll with special parameters in Labview?

Hi,
I have a dll file (compiled in C++) and I would like to call the individual functions from this dll file.
I do not know however, how I must correctly define the initial parameters in LabView.
That is the function, which I would like to call:
DWORD OpenDiagDriver ( char* port,
LPCSTR path,
CANObjects CANObj[],
WORD BitTiming = 0x4167);
CANObjects CANObj[] is a pointer to array with CAN configuration data
typedef struct
DWORD Ident;
BYTE Config;
}CANObjects;
CANObj[0].Ident= 0x18DA0000;
CANObj[0].Config= 0x8C;
CANObj[1].Ident= 0x18DA0000;
CANObj[1].Config= 0x84;
WORD BitTiming= 0x4167;
I made a vi, but it doesn’t work.

Hard to say without the full C source. Are you building the DLL according to the CIN rules (see Using External Code in LabVIEW)? Mapping clusters to C code in DLLs is not a simply process and we generally recommend to create wrappers. However, since your structures are fairly straightforward, you could use the "Adapt to Type" as you are trying to do.
I recommend checking out the mentioned manual and also the examples in \examples\dll\data passing\Call Native Code.llb and the associated C files.

How to call Fortran .dll file that using other library files?

Hi,
I am trying to do some arkward tasks using LabView, and I am desperately need help....
A little bit background:
1. My co-worker has some code written in Fortran, where he called other libraries (many from CERNLAB or PAW). Those stuffs are pretty powerful in mathmatical calculation and simulations.
2. In some of my LabView code, I need to call his Fortran source code in order to do some complicated calculations. I have no capablility to translate his Fortran code to Labview (or is it even possible??), so we end up with trying to use "Call library function node" where I just provide input/outputs to communicate with his code. The idea sounds simple enough?
3. We complie the Fortran code into .dll, and then specifiy the dll in "Call library function node". The first try with a very simple Fortran code, something like c = a+b*a, was sucessful. The dll file and Call lib function worked good. It's sort of proved the concept.
4. Now I am trying more complicated Fortran code (say Test.dll), which calling other library (.lib files) that using typical "call xxx(a,b,c)" line, and my nightmare started.... It seems nothing was excuted when I call Test.dll in LabView.
Questions:
1. How do LabView know if the Test.dll code needs functions from other .lib files? Do I need to copy all the .lib files to a specific folder?
2. When I create .dll file, for LabView to be able to use it, are there any special requirement on the way the .dll is compiled?
3. Seems there is mismatch btw the data type in Fortran and LabView. For example, LabView's Signed 8-bit Integer seems different with a integer in Fortran. How can i know the correlation btw data type in different langurage, i.e. LabView vs Fortran?
4. Are there any good examples that I can take a look?
I would highly appreicate any suggestions/helps!
Rgds,
Harry

You are aware that Intel Visual Fortran is the successor to Compaq Visual Fortran (I think you made a mistype with the Virtual)? So an upgrade might be at its place.
Anyhow I'm really not familiar with Fortran at all, but lib files are usually compiled into an EXE or DLL and not loaded dynamically. 1)
So there should be no problem with locating those libs. What most likely is a problem are other DLL dependencies such as any Fortran Runtime library or possibly other third party DLLs the more advanced code in your DLL might be using.
Typically most compilers can be configured to link the runtime library code statically into the DLL, as altenbach reports for the Intel compiler, otherwise you must make sure to install the redistributable Fortran Runtime Library for your compiler. Besides that you must make sure to find out what other runtime dependencies your code might have and install them.
1) One exception I know of is LabWindows CVI which allows to also load lib files dynamically. This is supposedly a legacy feature from LabWindows for DOS, which allowed that feature to simulate dynamic module loading in order to swap modules at runtime to work around the 640k memory limitation of DOS.

</OBJECT>
<script language="vbscript">
repExport.Exportfile="peiruyt"
repExport.CrystalConnect()
repExport.PassParameterRtp()
repExport.reportexport()
</script>
Because i need get parameter from other web page , and i use weblogic 6.1 server, so i need change file type from html to jsp , But even if I just change the file extension from html to jsp, don't change any content in this file.

How to call plsql procedure or function and getting back the string?

Hi Everyone,
i am using Jdev 11.1.1.5.0.
i have a requirement to call plsql procedure or function from my backing bean java file and get back the returned value from the procedure or function.
what piece of simple code i need to write in my backing bean?
please suggest.
Thanks.

As always you write the method to call he pl/sql in the application module, expose this method to the client (so you see it in the datacontroll) then create a operation binding to the method and call this operation from the bean. The result you get by operation.getResult();
You should never call pl/sql from the bean directly!

So, i called the wizard "Service Call".
In the Select Service step i have to input the destination and Function Module and
Before i specified an RFC destination .
The wizard cannot find the function.
I read the Note:
The function module must exist in the current system! The wizard does not support to call a remote capable function module that does not exist in the current system.
The question is :
How can i call remote capable function module?

How to call operating system(windows) functions like sutdown,refresh,et

Hello,
I am new in Oracle D2k.I want to know that how to call windows XP/7 shell commands(operating system functions) or windows function key(like F5 for system refresh in windows xp/7) in an Oracle Form.
Actually I have to make a trigger which can fire at pressing a particular key and execute appropriate action of Windows7 like shutdown,F5(function key of windows to system refresh).
thank you
regards
aaditya.

Just for future reference, regardless if you are posting in the Forms area of the forum or any other, terms like Forms 11g, Oracle 11g, etc are parts of product names. They are not version numbers although they do offer a slight hint. It is very important that when posting you include the complete version number of any products related to the problem or question you have. For example, you said you are using Oracle Forms 11g. Look at how many possible versions "Forms 11g" could possibly be:
11.1.1.1
11.1.1.2
11.1.1.3
11.1.1.4
11.1.1.6
11.1.2.0
11.1.2.1
With each new patch release and major release, a large number of bug fixes are included. In the case of new major releases, in addition to bug fixes, many new features are added. So knowing the version number is important.
Beyond that, it would appear that you have many questions:
1. How to copy and paste
2. How to execute a system shutdown
3. How to force the browser into full screen mode
4. Refresh - this one is unclear. What do you mean by "refresh"?
Let me answer those that I can:
<blockquote>o Functions like cut/copy/paste are available directly from your Forms code. For these I would recommend referring to the Builder's Online Help. Look for CUT_REGION, COPY_REGION, PASTE_REGION. It might also be helpful to understand SELECT_ALL. For example you may want to code a Copy button like this:
GO_ITEM('some_text_field);
SELECT_ALL;
COPY_REGION;o To execute a system shutdown on the client machine, you would first need to WebUtil enable your form. Refer to the Forms Builder Online Help for information about how to use WebUtil. You can also find lots of information in this forum about WebUtil. Once enabled, you can execute a Windows shutdown in various ways. Here one option:
Declare
     my_cmd varchar2(255);
Begin
     my_cmd := 'cmd /c start "" "' || '"shutdown -s -f -t 1"' || '"';
     WEBUTIL_HOST.HOST (my_cmd);
End;Refer to the Microsoft documentation for more information: http://technet.microsoft.com/en-us/library/bb491003.aspx
o I'm not sure what you are attempting to do with the F11. I understand that this function key sets the browser to full screen, but the form will not exactly adjust for this change in browser size. You can adjust the applet size dynamically, but not the form. For that you would need to code the behavior yourself. So, before I can offer something specific, it would be helpful to understand what you expectation is and if what you want is to set the browser to full screen, why not just allow the end user to do it? You could easily have a java script popup displayed before the form starts which might say something like "To maximize your browser, press F11"
o Finally, "refresh". I don't know what you mean here. Refresh what? The Windows desktop, browser, Oracle Forms.....
