OCCI problem with Borland
I try to compile OCCI example with Borland C and receiving this error in occiCommon.h:
typedef OCCI_STD_NAMESPACE::basic_string<utext> UString;
1) Too few arguments in template class name 'basic_string'
2)Declaration terminated incorrectly
I have the same task: using OCCI class in Borland C++Builder (v6) environment. Unfortunately, the only version of OCCI-class prepared by Oracle is for MS VC++. No one tool translate that, does not matter, whether you use ORAOCCI.DLL and implib.exe or ORAOCCI9.LIB and coff2omf.exe.

Re: Fwd: Link Problems With Borland C++ 4.52
I have seen this problem before in another context, and I'll offer the
cause and solution in the hope that they will apply to the Crystal problem.
Many Windows based applications rely on PASCAL calling conventions, which
change the way parameters are handled in function/method calls. They
indicate this by placing one of the following immediately before the
function name in the prototype declarations:
- pascal_far (or something like that)
- WINAPI
- some other typedef of either of the above
For example:
int WINAPI AddTotal(int valueA, int valueB);
Unfortunately, v2.0 of Forte does not provide any mechanisms for changing
the calling conventions of the prototypes in the generated C++ wrapper
library, so when you compile that code, the linker fails. I think that the
compiler may generate different symbols depending on calling conventions,
so that's why it fails.
To fix this, don't autocompile your code, but generate the distribution, go
into the generated C++ files and look for the function prototypes (I think
you can search for FORTE_NO_PROTOTYPES), add WINAPI to the appropriate
places in the prototype definitions (see above) and use fcompile to build
the library. Instructions for fcompile are in the Interfacing With
External Systems manual.
Hope this helps,
James

Thanks for your quick response. Yesterday we had been running down
the path of examining the calling conventions and trying to change them
to PASCAL, but without much success. After receiving your note, we
went back over it again, and this time we were able to finally to piece it
together. In addition to editing the Forte-generated .cc file to declare
the functions as PASCAL, we also had to turn off the compiler's case
sensitivity. (The Crystal .lib file had the function names in mixed case,
but the Borland compiler was generating all uppercase for the names.)
Now I had actually tried this yesterday and it didn't work (in fact it
generated a whole bunch of new errors) - because until we took a
second look at it today, I didn't realize that Borland's linker actually has
TWO flags that control case sensitivity. If you only turn one or the
other off, things can get pretty ugly looking. As soon as we turned
both of them off, the compile and link went beautifully. Again, thanks
for your help; hopefully we are over the worst of it now!
Dale

Problem with Borland Builder C++ AND NI-DAQ 6.9.3
Hello,
I am trying to porting a Data Acquisition application developed with Borland Builder 4.0 and NI-DAQ 6.5.1, changing data acquisition Hardware. Now I am using PCI - 6036E, with Ni driver version 6.9.3. My s.o. is Windows XP Professional.
When I link application with nidaq32b.lib and nidex32b.lib and launch my EXE, without call any DAQ function, when I close my window PC is resetting! If I try to use Ni driver version 7.0 or 7.3, I obtain a GP fault as soon I start program.
I think that there are problem of disallineament or other inside file EXE generated. I have tried to generate new file lib with implib utility from DLL, but with the same result.
If anyone cannot help me, I think to substitute call to DAQ functions inside C code with DLL or EXE developed in Visual Basic.
Can anyone give me any help for this? Is it better use VB 4.0 or VB 6.0?
Thank you for your attention.
FabrizioHi,
I would definitely suggest to create the dll in VB6. There are shipping examples for VB6, so that you can see how it looks to program in VB6 with DAQ. These examples can be found at C:\Program Files\National Instruments\NI-DAQ\Examples\VBasic.
I hope this helps. Have a Great Day!

OCCI: Problem with CreateConnection() method
I am using OCCI sdk for Oracle 10g database with VS2005. I am continuously getting an exception
"An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in OCCITest.exe
Additional information: External component has thrown an exception."
I get this exception at line:
user = "SYSTEM";
pass = "abc123";
db = "//127.0.0.1:1521/orcl";
-> con = env->createConnection(user, pass, db);
I have seen lots of posts with people asking this question... i tried almost all the alternatives specified in those posts. Even my Sqlplus works with this connection string. In sql plus, i can connect using these credentials, can create a table, insert data... etc. But I just can't connect from VC++...
For reference, I am pasting the entry in my tnsnames.ora file below:
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
I am using Vista machine. I have installed oracle 10g for vista. Can my OS be a problem? I will really appreciate the help...
Regards,
JwalantThis may be obvious, but please verify that you have first created the environment before calling CreateConnection...
Environment *env = Environment::createEnvironment (Environment::DEFAULT);
Connection *con = env->createConnection (<user>, <password>, <connStr>); -
Hi,
I have a problem with OCCI, when i create the connection the following exception appears:
ORA-24960 - the attribute OCI_ATTR_USERNAME is greater than the maximum allowable length of 255.
A piece of code:
string userName;
string password;
string connectionString;
userName = "lucas";
password = "lucas";
connectionString = "lucas"
printf("Imprimindo o valor das váriaveis \n\n");
printf("User name --");
printf(userName.c_str());
printf("\n");
printf("Password --");
printf(password.c_str());
printf("\n");
printf("Connection String --");
printf(connectionString.c_str());
printf("\n\n");
Environment *env;
Connection *cn;
try{
printf("Criando Environment. \n");
env = Environment::createEnvironment(Environment::DEFAULT);
printf("Environment criado. \n");

Problem with Application Login after upgrading to Oracle 11g
I have a home-grown application with Oracle 10g database running under Windows XP Pro. Recently, I installed Oracle 11g and imported the application database from 10g to 11g (still want to keep the 10g running for a while). However, I now having problem with the application logging into the new 11g database. (Keep getting invalid user/name message).
BTW, I have no problem accessing the 11g database through SQLPlus (logging in with the same name and password that I use for the application), and the connection test of NetManager (again using the same name and password that I use for the application) was successful.
The application itself uses the old Borland BDE (Borland Database Engine) to access the 10g and 11g database. Testing confirms that BDE can access Oracle 11g with no problems.
Any idea about the probable cause(s) of the problem?
Thanks in advance,
sg200011g by default is case sensitive username/password.
You can disable that with setting parameter SEC_CASE_SENSITIVE_LOGON to false.

Problem with OCI call and how to install and use 'DEBUG_EXTPROC' on Linux
Hi,
Can any one let me know how I can install and use this debug_extproc package. I have installed oracle XE server on Linux machine(32-bit).
When I use : DEBUG_EXTPROC.STARTUP_EXTPROC_AGENT' ... i get an error saying that : it is not declared.
I tried looking in all the directories but did not find the dbgextp.sql(which is required in order to install that package).And tried searching on google but could not get any relevant information.
Also I am newbie to OCI call interface and also to C programming too: I have coded a external procedure or custom user aggregate in C. But since I was using C++ : 'set' STL. I have compiled my program using g++ instead of gcc and I have correspondingly modified the make file in public/demo directory.
So, is it fine to do it that way: using OCI (instead of OCCI(C++)) but again compiling the pgm as a regular C++ using g++ instead of gcc.(But rest of the pgm including printf statements : everything is in C).
Also I have created the library from my : custagg.so library:
SQL> create or replace library custagg is '$ORACLE_HOME/lib/custagg.so'
But my aggregate function implemented as external C function using OCI is either not recognised or else : if recognized then there is some error because of which i am getting the following errors : ORA-06522
SQL> select MinDistance(TT) from egg1;
select MinDistance(TT) from egg1
ERROR at line 1:
ORA-06520: PL/SQL: Error loading external library
ORA-06522: /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/custagg.so:

Please kindly answers my queries and trying to resolve this for almost 4 days now and could not find any clue on how to get this done.

Using NI-DAQ with Borland C++ 5.01
Hi,
I've got a problem using Ni-DAQ with Borland C++ 5.01 (i know this section is for visual C++ but I couldm't find any for ANSI C++). If I write a simple program with one of the libraries included in nidaq.h and if i specify the correct lib and include locations I have a problem with the linkink process; in particular it says that the function can be resolved...
If anyone can help me I would appreciate it. Thanx
OptoclasfoHey optoclasfo,
I haven't used Borland much, but with Visual C++ the problem normally
happens because the lib and include paths are not added to the
project. For Visual C++ they are stored at
Tools->Options->Directories. If the library files (*.lib) are not
added to the project you can get this error as well.
I hope this helps out.

Linker problem with M series card
I am attempting to incorporate a PCI 625 DAQ M series card into a Borland C++Builder application. To get started I have used the code from the example "ContAccelSamps-IntClk-AnlgStart" in the documentation. I have added "nidaq32.lib" to the project and included "nidaq.h" and "NIDAQmx.h" as in the example.
Everything compiles correctly. However on linking I get the error message "NIDAQ32.LIB contains invalid OMF record, type 0x21 (possibly COFF). I am not sure what this means.
Is this a bug in NIDAQ32.LIB or am I missing something simple here?
In an attempt to resolve the problem I have rebuilt the library from the dll, but this doesn't work either, the new library is only 215 KB whereas the original one is 886 KB.
So as a su
bsidiary question might I ask how you build libraries from NI dlls.Hello,
I apologize for the confusion around this. Currently, the NI-DAQmx C import library for Borland is only installed with LabWindows/CVI DAQ support. However, I am attaching the NI-DAQmx 7.3 import library that you will need for Borland support. We are working on posting this in a Knowledge Base on our website. Here is a link to another discussion forum thread in which a customer used with borland's "coff2omf" to work-around the linker issues they were seeing. This link also discusses another problem you may run into with floating point initialization that you may need to take into account. Hopefully this information will enable you to get your application working with Borland and M Series. If not, please let us know.

Problems with PrintPanel/PrintCtrl
Hi
I have a very strange Problem with the Print-Functions!!!!
Since 1 week I have to use C++ Builder 3.0 from Borland
on my PC for development! I installed BC++3.0 and some Components!
Now I have the Problems with the Printfunctions!
If i call one, the programm hangs up with the message!
Error in Module GDI.exe!?!
Does anyone have the same experience or knows anyone a solution for my problem?
Thanks a lot
chrisHi Csound1
approx every 30 seconds the browser freezes and 'saving' appears in the top bar of icloud mail. The cursor starts spinning and then after about 8 secs I can start typing again. I also fiund that about 5-6 times a day my icloud browser tab showing mail just close and return to the main icloud menu page showing icons for mail, calender, notes etc -
I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
LeftyThis was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
boolean active = true;
public void run(){
ss.setSoTimeout(90);
while (active){
try{
serverSocket = ss.accept();
catch (SocketTimeoutException ste){
// do nothing
// interrupt thread
public void deactivate(){
active = false;
// you gotta sleep for a time longer than the
// accept() timeout to make sure that timeout is finished.
try{
sleep(91);
}catch (InterruptedException ie){
interrupt();
} -
Problem with Threads and a static variable
I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
Code functionality:
A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
The problem as far I understand is:
Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
Thanks,
B.D.
Code:
private static volatile boolean bChanged = false;
private static Thread objMainProcess;
protected static void Init(){
objMainProcess = new Thread() {
public void run() {
while( objMainProcess == Thread.currentThread() ) {
GetState();
objMainProcess.setDaemon( true );
objMainProcess.start();
public static void initStatusTimer(){
if(objTimer == null)
objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
public void actionPerformed( java.awt.event.ActionEvent evt){
SetState();
private static void SetState(){
if( objMainProcess == null ) return;
synchronized( objMainProcess ) {
bChanged = true;
try{
objMainProcess.notify();
}catch( IllegalMonitorStateException e ) {}
private static boolean GetState() {
if( objMainProcess == null ) return false;
synchronized( objMainProcess ) {
if( bChanged) {
SendMessage();
bChanged = false;
return true;
try {
objMainProcess.wait();
}catch( InterruptedException e ) {}
return false;
}Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
Again as you said, There is a reason I can't call sendMessage() inside setState().
The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
Thanks,

Problem with threads running javaw
Hi,
Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
troy.troy,
Try and post a minimum code sample of your app which
does not work.
When using javaw, make sure you redirect the standard
error and standard output streams to file.
Graeme.Hi Graeme,
I dont understand what you mean by redirection to file? some of my code below.
The code works fine under a console, code is supposed to exit when the client (the other server )disconnects. the problem is that but the clientworker side of the code still works. which under console it doesnt.
public class Server{
