OCI header files

Can I build OCI programs with the 8i I downloaded?
If not, it's not worth the trouble installing it...
Pleaze answer!

MISSING OCI Header Files

The OCI header files are missing from the Oracle 8 for Linux
trial CD. Everything else works fine, but we can't develop any
client applications without an OCI interface.
I tried using the header files from Oracle 8 Solaris SPARC, but
the resulting program core dumps in olog().
Does anyone know where I can get these files? If a purchase a
production version, will they be included?
I have a bare bones Linux ODBC driver for Oracle that I cannot
compile without them.
Thanks,

Session variable and Tracking in Header file

Is there a way for me to keep track of the session and use a variable in my Header to pass around for this?
I have a login.jsp, validate_login.jsp and other jsp's that have the same header file. Instead of me using the same code in all of the jsp's I thought it would be easier to put it in the header Please look at the example code below:
// validate_login.jsp is passed username and password from the login.jsp.
// validate_login then calls the logIn method in my Session class.
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@page import="uom.edu.rd.session.Session"%>
<html>
<head><title>Validate Login</title></head>
<body>
<jsp:include page="header.jsp" />
<%
 String username = request.getParameter("username");
 String password = request.getParameter("password");
 this_session.logIn(username, password);
 boolean b = this_session.getLoggedIn();
%>
==================================================================
// The logIn method in Session class
public void logIn(String userName, String password) {
 Connection con = null;
 Statement stmt = null;
 ResultSet rs = null;
 try{
 con = db.getConnection();
 stmt = con.createStatement();
 String sql = "SELECT * FROM RD_USER WHERE USER_NAME = '" + userName +"' AND USER_PASSWORD = '" + password + "'";
 rs = stmt.executeQuery(sql);
 if(rs.next()){
 loggedIn=true;
 }else{
 loggedIn=false;
 catch(Exception e){
 // If something goes wrong, make sure
 // the user is not logged in.
 loggedIn=false;
 }finally{
 try{
 rs.close();
 stmt.close();
 con.close();
 }catch(Exception e){
 * Log the user out.
 public void logOut() {
 loggedIn = false;
 * Get the login status.
 * @return boolean
 public boolean getLoggedIn() {
 return loggedIn;
==================================================================
// and this is part of my header.jsp
<%@page import="uom.edu.rd.session.Session"%>
<%
Session this_session = Session.findSession(request);
if ( this_session==null ) {
 /* Now, instead of redirecting, create a new Session
 * object and initialize it.
 this_session = new Session();
 this_session.makeSession(request);
 this_session.createQueryBuilder(config);
%>
// This is the part I would like to pass around

<%
 boolean loggedIn = this_session.getLoggedIn();
 if (loggedIn == false)
 { %>
 <A STYLE="color:#FFFFFF;text-decoration:none;" HREF="./login.jsp">LOG IN</a> 
 <% } else { %>
 <A STYLE="color:#FFFFFF;text-decoration:none;" HREF="./logout.jsp">LOG OUT</a> 
 <% }
%>
// so if you are logged in then you are able to view certain things on the jsp's if you are not logged in
// then of course you cannot. I want to pass around this loggedIn variable to all the jsp's
// after it checks loggIn Status for each page I have tried running this but I keep getting an error: cannot resolve symbol this_session

Use <%@ include file="header.jsp" %> instead

How can I use a dll if I dont have a header file

I'm not sure if I'm even trying the possible here as I have searched and not been able to find much at all. However I figured it was worth asking here.
I have access to several dll's used by a program, I need to open a file using the program (for some reason it is completely non responsive unless you open it "within" the program itself) and so decided to browse the .dll files included. Ive found a few functions which may carry out the function I need. Is there a way of figuring out the inputs/outputs if I don't have documentation or a header file?
This is the next stage in a huge project I am working on at the moment and I've been banging my head against the wall all day trying to figure this out.
Thanks in advance for any help

That glass?
Thats glass is neither half full or half empty....
Its twice the size it needs to be

Yes, that makes sense. It also means that what you are trying to do is not likely to work. You have no way of knowing what the program does when opening the file, so guessing at using the DLLs is purely a shot in the dark without even knowing where the dark is. Even if you could find the function (assuming it's just one) that loads a file, how is the program supposed to use it now? That function has to be called from within the program. When you call it from LabVIEW you are not sitting inside the program's memory space, so it has no way of knowing about the file.
I would suggest, instead, to see if the program accepts command-line parameters. For example, does it accept a name of a file to open as part of launching it from the command line? If not, then you may need to resort to trying to control it via automation. If it has no built-in automation then you need to resort to using the OS to make pretend you're clicking buttons and typing text. This has come up many times before, and there have been numerous posts on this, so please do a search on controlling an external program from LabVIEW within this forum. You can call the Windows API functions to move the mouse to a specific location and click the button as well as typing text, or you can use third-part automation tools. One that I have used successfully is AutoIt. The search I indicated will yield other suggestions.

How to use preprocessor directives (#define) in C++ header file with LabVIEW 8.2

I have a C++ header file that contains around 2000 preprocessor directives:
#define MEM_1   0xC
#define MEM_2   0xD
#define MEM_3   0x18
I want to be able to "access" these memory offsets by identifier name (MEM_1) in my LabVIEW program like I would in a C++ program. I do not want the overhead of parsing through the header file and storing all the offsets into an array or similar structure.
I've written a simple Win32 console program to return the memory offset given the identifier (see code below), and created a DLL to use with my LabVIEW program. In the console program, you notice that I can call a function and pass in the identifer name, and get the offset back correctly:
getOffset(MEM_1);
In LabVIEW, I was hoping to be able to pass in the identifier (MEM_1) but was unsure what datatype to use. In my C++ code, I defined the parameter as an int. But in LabVIEW, I can't enter in MEM_1 as an int.   Can someone advise on how to do this? Or if there is an alternate way to use #define's from external code inside LabVIEW?
#include "stdafx.h"
#include "scrmem.h"
#include "stdio.h"
void getOffset (int var);
int _tmain(int argc, _TCHAR* argv[])
getOffset(MEM_1);
canf("%d");
return 0;
void getOffset (int var)
printf("The address of MEM_1 is %x", var);

kaycea114 wrote:
Hi,
Where do you think I should use the string?
The way that getOffset is currently defined in the DLL, I have to connect an integer input into the LabVIEW function. This prevents me from entering in: MEM_1 as the input to the LabVIEW function.
Are you suggesting that I change getOffset to receive a String parameter ("MEM_1")? Does that mean I need to do a string compare (line by line) through the header file to get the offset? It seems like doing this search through the header file would degrade performance, but if that's the only work around, then I'll do it.
Please advise.
Well, what you want to do is indeed entering a string and getting back the assigned integer. That is what the C preprocessor is doing too although there it is done only once at the preprocessor stage of course and not at runtime anymore. But LabVIEW is not a C preprocessor.
What you did so far seems to be to define getOffset() that accepts an enum that needs to be created from the C source code to then return the assigned constant. That's of course not very helpful.
And writing a VI that could parse the C header file and create a name/constant array is really a lot easier than doing the same in C. You don't even need to parse the file each time again, but can instead cache them in an uninitialized shift register (LV2 style global).
Even more easy would be to create from that data a ring control using property nodes and save it as custom control and voila you have the most direct lookup you can get in LabVIEW and it works just as comfortable as using the define in C code. It would mean that you need to seperate your header file possibly into several different files to only get related constants into the same ring control, but that is easily done.

Header file entry for Text Channel

I have taken an ASCII Text Data file, read the file, and created a Header File, then saved the data into a binary file. This is my attempt to speed up the loading of the text file. One of the columns is a text column, containing a flag for the state of the test. I can not figure out how to define the column as a Text Column in the Header File. If I define it as a numeric column, it returns an error for every entry in the data file. Normal (one of the states) is not a Numeric Value.
The script file(s) I am using is a modification of a script listed on this board by Brad Turpin ( TimeSlice DAT Hdr Create.zip ) The only thing I have changed is the Test for the Channel Name to see if it contains on of 3 states. If Date is present in the Channel Name , it changes the field to a Time channel, if the channel contains Relay it changes it to a Text channel (which doesn't work), else the Channel is a Numeric.
There must be a way to define a Text Channel in a Header File. I hope someone can show me the way.
Thanks

Hello Bill!
The DAT format was never able to store text channels (TDM is able today). Please refer to the DAT format description on your DIAdem CD or in this post.
Your idea to convert it to a numeric value is the right way. The error message must come out of the header. Do you convert all properties to numeric values? See page 4-6 and following in the header description or search for the word 'normal' in the created header file.

Problem while including the header file in C source code in CIN

While Creating code interface node....
In the C source code we are supposed to include the Header file "extcode.h".In my system i have installed
Turbo C. I couldn't able to find the above header files.When i am trying to use the above header file i am getting error,what could be the reason

Hi,
You need to point your turbo C to ..\labview\cintools which is where you will find the extcode.h and other h file and also the lib file.

Create header file based on data in Data file

Hi,
For Data File: created an interface to extract data from table to data file.
1) Now i want to create a header file which contains info like :
Created On: #Rows Fetched:
2) I also want to create a footer, which contains info like:
SUM(AMOUNT) (amount is one of the columns of data file)
How do i implement this using an interface?
Thanks.

Step 1. Create a Variable Header - Call the count using some thing like this SELECT COUNT(*)||CHR(10) FROM TABLE
Step 2. Call it in OdiOutFile
Step 3 . Call the Interface to load from table to File using [ IKM SQL to File Append with create Header option - no ]
Step 4. Create another Variable Footer - Call the sum in the Refreshing Tab
Step 5. Call it in OdiOutfile with Append option Checked
Note - Make sure you use the same File Name for all the three places.
There are other ways too but this is simple way. Hope this helps.

How to include header files from different directories?

Hi,
Sorry for the newb question, but I can't figure this out. I'm trying to compile a simple piece of code (C++) that uses header files in a directory different from the Project directory; header files are in /opt/csw/postgresql/include/pqxx. I've tried a few different things, adding that directory to the include directives under Resource Files, add existing files from a folder, etc etc. Whenever I try to build, dmake bails with status -1. I can't seem to get this working, can someone explain how to use header files from different directories?
Thanks,
SlowToady

Header files are usually specified relative to a base directory. If the base directory is not a system directory -- /usr/include or the compiler installation directory -- add a command-line directive
-I path/to/base/dirfor each such directory.
The path can be absolute, such as
-i /opt/csw/postgresql/includeor relative, such as
-I ../../my/includeIn your source code, specify the header file relative to the base directory, and be sure to use quotes, not angle brackets. Example:
#include "header.h" // right
#include <header.h> // wrongThe angle brackets are used for system headers, like <iostream> or <stdlib.h>.
The rules above are common to all compilers on Unix and Linux, and generally to all C and C++ compilers.
For more details, read about the -I option in the C++ Users Guide. You can find the guide by pointing your browser to the "docs" directory in the compiler installation, or go here:
http://docs.sun.com/app/docs/doc/819-5267
All command-line options are described in Appendix A.

Do I need to declare my custom setter accessor in my interface/header file

Hi there:
I'm working through a Objective C tutorial. I've got an instance var that is declared in the var section of my @interface (in the header file). It's also declared as a property...all the defaults apply (assign and whatever else).
@property int foo
I also have it synthesized in my @implementation code.
@synthesize foo;
I need a custom setter though that checks out the value being assigned. Do I need to declare this setter function in my @interface section in the header file?
-(void)setFoo:(int)newValue {
if (newValue < minAllowed) {
NSLog(@"Invalid foo: %i is less than the minimum of %i allowed", newValue, minAllowed);
return;
if (newValue > maxAllowed) {
NSLog(@"Invalid foo: %i is greater than the maximum of %i allowed", newValue, maxAllowed);
return;
foo = newValue;
} // setFoo()

The @property statement is the declaration of the accessor methods whether they are synthesized or custom coded.
For a fairly clear, detailed explanation see Accessor Methods in the +Memory Management Programming Guide for Cocoa+.

A hperlink for a header file in a c/c++ project

Hi,
How can I configure a c/c++ project, so that the #include directive will be
followed by a header file name with a hyperlinlk (so that clicking on it
will cause the editor to jump to that header file ? )
Mark

Mark,
I guess you are using makefile-based project (i.e. "project from existing sources"), right?
In this case you should somehow "explain" the built-in parser where to search your include files. There are two ways of doing that:
1) Manual: in Project View context menu:
Project Properties -> Parser Configuration -> C Compiler (or C++ Compiler) -> Include Directories
2) Automatic: in Project View context menu, select "Configure Code Assistance"
To use this, you have to first build your project with debugging information. The "Configure Code Assistance" mode uses this information to correctly determine what include paths were used.

Vladimir

How to include header files with different extensions

Hi,
When i include a header file with extension .ch (myincludefile.ch), the compiler gives error messages but when i change the extension to .h, the problem disappears.
Can anyone help me getting rid of this problem?
For example, for the line below, I get a warning such as, "attempt to redefine MY_CONST without #undef". Remember when i change the extension to .h, the problem disappears.
#define MY_CONST 500 /* Constant */
Thank you very much

I don't see how the name of the file could cause or prevent error messages, except when template declarations are involved. So let's assume for now that the file has a template declaration.
The Templates chapter of the C++ Users Guide explains about including or separating template declarations and their definitions.
If you have only a template declaration in a file and the compiler needs the definition, it will look for another file with the same base name and include it automatically. For example, if you have files foo.h and foo.cc, and foo.h has a template declaration, the compiler will include foo.cc automatically, even if you didn't intend for that to happen. You can wind up with multiple delcaration errors that way.
When looking for a file containing template definitions, the compile will not include a .h file, so as not to create recursive inclusion. If changing the file name to .h causes your problem to disappear, it seems like an unwanted automatic inclusion is the problem.
You can try two things to find out:
1. Compile with the -H option. The compiler will output an indented list of all included files. See if you are getting a file you didn't intend, or the same file twice.
2. Compile with option -template=no%extdef. It disables the automatic search for template definitions.
If you find an unintended included file this way, you will probably have to change the names or organizaiton of some of the files. Our implementation of the C++ standard library depends on NOT using the -template=no%extdef option, which might mean you can't use that option.

A question about /usr/include/sys/select.h header file

good day! i hope i can get some help about this and i would be very grateful if my question will be answered. i have a question regarding the select.h header file that we include in our programs when we use the select(3C) function.
* Select uses bit masks of file descriptors in longs.
* These macros manipulate such bit fields.
* FD_SETSIZE may be defined by the user, but the
* default here should be >= NOFILE (param.h).
29 #ifndef FD_SETSIZE
30 #define FD_SETSIZE 1024
31 #endif
its says here in the header file that the value of FD_SETSIZE may be defined by the user and i need to know how. i've already tried declaring a constant at the beggining of the program but it didn't work...
example:
#undef FD_SETSIZE
#define FD_SETSIZE 2048
the FD_SET macro generates an error if a value larger than 1024 is passed from in the first argument. i need to increase its value in order for me to wait for more than 1024 socket descriptors on select function. how can i increase or modify its value? thanks in advance...

AFAIK, the only way to change the FD_SETSIZE value is by building your own version of the libc.a and linking it statically to your executable. Not good at all IMHO.
The sources of Solaris 8 contain the implementation of select(3C) with both standard and 'large' (64K) FD_SETSIZE.
AFAIK, 64-bit version of the libc.so contains the 64K-descriptors version of the select(3C), so you may consider building your application with -xarch=v9 flag to get 64-bit application...
As for poll(2) - there is a manual page (man -s 2 poll) and some notes in the Answerbook. poll(2) is the actual system call that is used by select(3C), which is an interface function, so there is no functional difference between these two.
There is a potential problem with portability of your code if you are using poll(), but it looks like you have no choice... sorry about it...
