tion is running fine without giving any error messages. But even after the vi stops, excel process does not shutdown. "Excel.exe" process keeps running until I end it from Windows NT Task Manager. Is there any way to end the excel.exe process from Labview?I use Excel Active X control frequently to save and then analysis test data. In order to properly destroy the "Excel.exe" process it is important to close all the automation refnums opened when using the Excel active x controls. After completing your desired Excel task wire all the refnums in reverse order they were created into the Automation Close function in Functions->Communication->Active X pallette. This includes all Application, Workbook, Worksheet, or Range refnum. Missing even one of these refnums will mean that Excel.exe will still persist in the task manager and cause problems when excel is opened from outside LabVIEW. I hope this helps.

How can i use activeX Control in labview?
how can i use activeX Control in labview?
please describe me step by step.
thanks.Well..that was quite helpful..but now I'm encountering certain problems. I've attached the VI I've made.
I don't need sound at the moment so I dropped it. (Although I tried to play it..but all I could hear was a very annoying sound.) Secondly I don't want to display any date or time..so i dropped that property too.
Now when I run this Vi...the webcam turns on, the screen of videocapx pops up..then the webcam light goes off..and another pop up appears saying..labview is not responding..and i have to close it reluctantly.
I haven't placed the stop capture property in this vi. i checked it by placing it too..but that doesn't work.
I would like to notify that my actual task is to acquire image and then compare it with another one already present on my pc. I want you to please help me out..solve my first query then I'll proceed with the latter part.

Using Cursor and FOR LOOP to INSERT the data into table
Hi all,
I have SELECT statement that returns 3 rows:
PROCESSNAME

2013-12-04
SELECT processName, MAX(NVL(protStartDate, protCreateDate)) AS protDate

}",sem_models("PROTS", "LINEARS"),NULL, SEM_ALIASES(SEM_ALIAS("","http://VISION/Data/SEMANTIC#"),SEM_ALIAS("s","http://VISION/DataSource/SEMANTIC#")),NULL))
Group by processName
Now I need to INSERT these values into the table along with the other values.
these other values come from different table.
INSERT INTO MODEL_CLASS_COUNTS (MODEL_NAME, CLASS_NAME, INS_COUNT, COUNT_DATETIME, PROCESS_NAME, PROT_DATE)

SYSTIMESTAMP, %%here need to insert PROCESSNAME, PROTDATE%%
t was giving me error:
PL/SQL: ORA-22905: cannot access rows from a non-nested table item
so i enclosed sparql query into single quotes.
The code is as follows:
declare

loop
fetch cur into v_process, v_pdate;
exit when cur%NOTFOUND;
--here I need to insert v_process , v_pdate into my table along with other values...
dbms_output.put_line('values for process and prod_date are: ' || v_process || v_pdate );
end loop;
close cur;
end;

Now, I get an error:

Does anyone know way around this?Hi,
I tested something similar with insert into select and it worked fine :
insert into t_countries(ID,CITY ,POPULATION, DESCRIPTION, located, insdate )
SELECT 1 id, city, o , city||' is a nice city' description, max(nvl(locatedAt,'unknown')) as located,
SYSTIMESTAMP
FROM TABLE(SEM_MATCH(
'{GRAPH :gCH {<http://www.semwebtech.org/mondial/10/countries/CH/> :hasCity ?cityID .
?cityID :name ?city .
OPTIONAL{?cityID :locatedAt ?locatedAt .}
?cityID :population ?o .
SEM_Models('VIRT_MODEL_MONDIAL'),
SEM_Rulebases(null),
SEM_ALIASES(SEM_ALIAS('','http://www.semwebtech.org/mondial/10/meta#'),
SEM_ALIAS('prv','http://www.semwebtech.org/mondial/10/countries/CH/provinces/')
null))
group by city,o
order by city;
Or with execute immediate :
declare
v_country varchar2(200) :='http://www.semwebtech.org/mondial/10/countries/F/';
v_text varchar2(2000);
begin
v_text := 'insert into t_countries(ID,CITY ,POPULATION, DESCRIPTION, located, insdate )
SELECT 1 id, city, o , city||'' is a nice city'' description, max(nvl(locatedAt,''unknown'')) as located,
SYSTIMESTAMP
FROM TABLE(SEM_MATCH(

null))
group by city,o
order by city';
dbms_output.put_line(v_text);
delete from t_countries;
execute immediate v_text ;
commit;
end;

How does labVIEW use ActiveX controls?
How does labVIEW use activeX controls?
I recently wrote an activeX control in VB and noticed that it would not work if the control was set so that its properties could not be set in ambient mode. This may suggest that labVIEW uses some activeX controls only in ambient mode.
Is this the case or are there more complexities?Dan,
Which version of LabVIEW do you have?
As per the KnowledgeBase bellow, in versions of LabVIEW prior to 5.1 you would get errors accessing the ambient properties.
ActiveX Controls in LabVIEW 5.0.1 Containers Cannot Access Ambient Property
Do your controls use the Ambient.UserMode to determine when the control is being used in a development environment? When embedding ActiveX controls into a container on the front panel, by default, the ActiveX control generates and responds to events, i.e. it is running, even when LabVIEW is in edit mode.
Right-click an ActiveX container and select Advanced»Design Mode from the shortcut menu to display the container
in design mode while you edit the VI. In design mode, events are not generated and event procedures do not run. The default mode is run mode, where you interact with the object as a user would.
Information can be found in the LabVIEW help files

Post Author: jimmyp
CA Forum: General
We have a problem with printing crystal report over web using ActiveX Control. When clicking print button, it only shows a blank dialog web crystal viewer page without any error. The page just simply hangs. We installed the PrintControl DLL and enable all the security setting for ActiveX Control for IE. It still does not print. Does anyone know why?
Environment.

Is it possible to call a activeX control from PL/SQL...?
Hi all,
Is it possible to call a activeX control from PL/SQL...? If yes, please give me sample code or any link.
Thanks,
PalThe LoadLibrary() Win32 call is used to find the physical DLL and load it into memory. This API call first look in the current directory for the file, and then uses the PATH environmental variable to try and find the file.
Thus you need to make sure PATH is properly set. A Win32 process runs in a 32bit VM (Virtual Machine). Been a very long time since I did Windows server side development, but as I recall this VM inherits the default o/s environment (unlike Unix where the parent process environment is inherited).
You can set the environment using the Properties menu of the System desktop icon (or via Control Panel).
However.. Oracle does not run as your user. Typically it is installed as the o/s user Oracle and this user owns all the Oracle processes (listener, instance, etc).
So you will need to make sure that this user's environment is correctly configured... Further more than this, I'm out of my depth. Did a lot of Windows stuff back in the 90's, but for many years now I'm only using Unix/Linux professionally - with Windows being my console platform for playing games at home. :-)
On the Linux/Unix side, I configure the environment variable via the Listener. E.g. Under the entry SID_LIST_LISTENER, I configure the external procedure handler as follows:
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME=/tjs-dev/app/oracle/product/10.2.0)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ANY")
)No idea how this applies and works on the Windows side. -
Problems using ActiveX controls
Hello all,
I bought a set of ActiveX controls provided with a installation routine.
Using those controls within LabView after installing them were no
problem, but for distribution purpose I have to install those ActiveX
controls manually.
So I tried to do it on a separate computer by registering the ActiveX
controls with regsvr32 [regsvr32 ]. But the attempt to
start a LabView program where these controls were embedded ended with
the error message "error opening document" (ole_lv5container) and "error
510 occurred while loading ActiveX control ..."
I'm working with Windows NT 4.0 and LabView 5.0f2.
Does anyone know, what I made wrong?

Using ActiveX controls in GUI application, which uses TestStand API
When using ActiveX controls in TestStand Operator Interface GUI,
CVI reports User Interface Library error no.-143:
"ActiveX control Error" on attempt to load panel, which contains ActiveX controls.
The same code, which takes care of user interface, but not references
TestStand ActiveX API (i.e. not creates TS Engine), works properly.
What's wrong?Hello again Misha,
Sorry about my previous answer, I overlooked the fact that you were saying this error was caused by placing ActiveX controls in your Operator Interface (OI) GUI (as my example shows I thought the problem was with GUIs displayed from step code modules).
Nevertheless, the problem is still being caused by the same issue, and is solved in a similar fashion. The source for the CVI OI initializes the TestStand engine before it loads/displays the UI panels. The calls to initialize the engine seem to be CoInitializing the main GUI thread as multithreaded apartment (MTA) mode whereas you will need it to be single threaded apartment (STA) mode in order for the ActiveX control container to work properly. The TestStand engine is compatible with either modes, but only one can be in place at a given time. If we CoInitialize the OI's main GUI thread as STA this will solve the problem (the subsequent attempts of setting it to MTA will fail, but again this is ok since the engine is compatible with STA).
In order to perform this functionality you will need to put a call to CoInitializeEx in the main function of the CVI OI source (this will also require that you #include the "windows.h" file at the top of the source also). Here is what the main function in your main.c file for the CVI OI will look like once you have done this:
int main(int argc, char **argv)
int retval = -1;
sArgc = argc;
sArgv = argv;
if(InitCVIRTE(0, argv, 0) == 0) /* Initialize CVI libraries */
goto Done; /* out of memory */
// Intialize main GUI thread as STA to prevent other attempt to make it
// MTA, which will not allow ActiveX controls to be used.
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
/* initialize the test engine */
if(!InitEngine())
goto Done;
if(!InitErrorDialogStrings())
goto Done;
if(!InStandaloneExecutable() && !DisplayRunningInEnvironmentWarning())
goto Done; // get out now
if(!ProcessPreLoginCmdlineArgs())
goto Done;
if(!CfgFile_Load())
goto Done;
if(!CfgFile_RestoreOptionSettings())
goto Done;
if(LoadGUIPanels() < 0)
goto Done;
if(!InitFileQuickList())
goto Done;
/* set initial gui state */
if(!InitGUI())
goto Done;
RunUserInterface();
retval = 0; /* normal exist status */
Done:
/* cleanup */
SeqFileList_DeleteAllSequenceFileRecords();
ExeList_DeleteAllRecords();
IconList_DeleteIconList();
SaveAndCleanupFileQuickList();
CfgFile_SaveOptionSettings();
CfgFile_WriteAndCleanupForExit();
AdaptList_DeleteAdapterList();
DestroyToolMenus();
CloseEngine();
FreeErrorDialogStrings();
return retval;
Note: Remember to #include "windows.h" at the very top of the main.c file and to include ole32.lib in your project file list in order to link in the definition for CoInitializeEx.

Query about use activex control in Developer form
I'm an oracle developer and My name is milton datta.I cant' use activex control in forms.Pls. anybody would help me how to use activex control in developer forms.If possible provide me with some examples.
my email address is [email protected]Download the Oracle Forms demos and you'll see a sample.
Also read the documentation for Oracle Forms 6i the developer guide has a section about Active/X.
Just remember that they will not work once you take your Forms to the Web. So think twice before you use them. -

I have an apple tv 3 but when i use Home Sharing from my Windows Laptop the Apple TV shows all my music on the TV but it will only play 1 or 2 songs and then stops!!! Annoying, so I have to re-start iTunes on my Laptop and it will play 1 or 2 more songs then stops again!!! still annoying.
Can anyone assist me with this issue?
ThanksTo downgrade, you'll need to download the previous software version here: ATV3 http://appldnld.apple.com/AppleTV/041-4361.20120605.grjot/AppleTV3,1_5.0.2_9B830 _Restore.ipsw
ATV2: http://appldnld.apple.com/AppleTV/041-4362.20120605.t8i4U/AppleTV2,1_5.0.2_9B830 _Restore.ipsw
Next, plug the Apple TV into your computer with a micro-usb cable (most phones today use these) and start up Itunes. It should detect the Apple TV in recovery.
After that, hold down Option on Apple or Alt on Windows and click Restore. This should open a window that allows you to select the software update you want to apply. Select the one you downloaded earlier.
It will then go through the restore process, which takes only a few minutes, and then you will be able to plug the Apple TV back in to your display and set it up again.
I recently ran into a similar issue with a bunch of these things and after restoring them all to the previous software version they are working again.
