We have an Access Database on a server and our test machines use an ODBC DSN to connect to it. Works great, but now our company is forcing us to move test machines behind a firewall. However the server with the database is not moving behind the firewall.
Does anyone know what port on the firewall must be open for ODBC connections to work? Is there a better way than ODBC to make the connection to the database?
Thanks
I have LabWindows/CVI 8.0.1 and Visual Studio 2013. I'd like to convert a project from CVI to VS. The wizard to do so ( in VS ) isn't present and I can't install it as the CVI installer looks for VS 2005 ( only? ). It states you must have VS 2005 or higher installed but I'm guessing since the CVI 8 installer had no concept of VS 2013 when it was released that it doesn't realize 2013 is newer than 2005. Is there a work-around, a patch that updates the wizard, etc. I can use? Thanks.
I am using CVI 2013 and I have several tools that I use to automatically generate and send emails. These tools leverage the outlook2000.c, outlook2000.h, and outlook2000.fp modules. The code was primarily taken from the Samples directory within the CVI2013 directory.
Recently my company loaded Lync 2013 and since that point I am getting the "Active X - library not registered" message. My guess is that this is due to the install of Lync2013 affecting some of the modules that are using in the Outlook 2000 environment.
Are there new Source Modules and Instrument files to support migration to Outlook2013?
Thanks!
Hello,
I get an error on my CAN module after a crash system (randomly happen). An error message ask me to look at the nicanErr.txt. I have no idea of what does it mean. Anyone can help me on the interpretation of this file ?
Thanks,
Hi everybody,
I am making a program in LabWindows and so far I have got two instruments running without any problems. But I am trying to add an NI USB6008 to the program. I have downloaded something called "NIDAQmxBase" and added a file called "NIDAQmxBase.h" but I can´t find the ".fp" file and therefore I have no functions to communicate with the instrument.
Can anyone help me?
I'm looking at reviving my CVI support and updating from CVI 2009 to the current one.
To help justify the plunge I'd like to know more about plans for CVI2015:
Background / Context:
I don't mean to be overly negative - CVI does great things for us, but these two complex (and hard to control!) issues really are the two pain points that I'd like to see progress on.
Thanks,
Ian
Hi All,
I'm having problems running a function in more than one thread at the same time.
The error is returned from the analysis library, so I guess my first question is "Is the analysis library thread safe?" (Specifically, Vector & Matrix Algebra functions.) I have looked through the documentation and cant see a statment either way.
Although I have a workaround using locks placed around all analysis library calls, I'd like to get to the bottom of this - it's got me a little worried because I've multithreaded other programs using matrix functions from the analysis library...
Another reason is my propgram processes quite a bit of data, so I'm confident I'll get a noticable speed improvement if I could remove the locks.
I've coped a chunk of code below.
The function works fine if:
a) it is run in a single thread only,
OR
b) running in multiple threads with USE_THREAD_LOCKS defined.
The function dosent work when:
Running concurrently in multple threads, and USE_THREAD_LOCKS is not defined.
In this situation, I get a fatal runtime error at one of the matrix functions -Transpose(), MatrixMul(), or InvMatrix(). The error does not always occur and is rarely in the same place, but always comes with a message about an undersize output array.
To give one example with some detail:
A fatal run time error occured at InvMatrix(), with pointer C highlighted and error message:
"Array argument too small (72 bytes). Arguement must contain at least 168 bytes"
But C is appropriatley sized as 9 doubles, given the matrix size is 3x3.
While other threads are running my function at the time of the error, no other threads appear to be using the analsys library.
I've looked over this code a hundered times, looking for unsafe variables but cant see anything.
Any ideas?
Diz.

I am using CVI 2009 and I am trying to create a distribution with CVI RTE 2009 but the cab file contains cvirte 2013. The RTE files in the System32 folder are 2009 but I also have RTE 2013 files in the SysWOW64 folder. How can I build a distribution with the 2009 RTE? (Customer requirement)
Hello,
I have a table control on a panel with 'hot' control mode.
When I use the scroll bar and scroll through the data it appears that the table loses focus after scrolling is complete. The focus is set on another button on the panel.
I amupdating the table contents periodically through a timer callback. In this routine I set ATTR_VISIBLE for table to 0 at beginning of routine and then set back to 1 at end.
I guess I'm expecting that the table would retain focus if the user scrolls through the data.
Does anybody know any tricks or workarounds to accomplish this?
Thanks,
Hello, I'm trying to draw an x-array and a y-array using ploXY function; but an inclined line is composing on my graph. I'm using that code:
plot_handle = PlotXY (testler, TESTLER_GRAPH, inputNumber, amplitude, 1024, VAL_INTEGER, VAL_DOUBLE, VAL_THIN_LINE, VAL_EMPTY_SQUARE, VAL_DOT, 1, VAL_RED);
In this code, inputNumber is an integer, amplitude is a double value. I'm drawing a point in the each 'for' loop using the plotXY in the above; but an inclined line that is between 0 and the last produced point, is also composing together with my correct points.
How can I prevent this inclined line?
Hallo,
here's a problem with a numeric control.
I have a control wich accepts a pretty large range of values: 0.01 to 60000.
What I want to do is changing of its incremental value in dependence on the current range.
So, if the control value is 2000..6000 to change it in step of 1000, if it's below 2000 but above 200 - in step of 100 etc.
The following code works if I change the value of the control with SINGLE mouse-clicks. But if I just press the left mouse key and hold it, it doesn't work!
Debugging shows, that it treats events correctly and passes the attribute to the control (also correctly). But changing of ATTR_INCR_VALUE seems to have no influence until I release the mouse key.
------------------------------------
int CVICALLBACK SetTint (int panel, int control, int event, void *callbackData, int eventData1, int eventData2)
{
float dIncValue=10.0, dIncValue_temp;
switch (event)
{
case EVENT_VAL_CHANGED:
GetCtrlVal(hMainPanel, MAINP_INTTIME, &fTint);
if (fTint>2000.0) dIncValue=1000.0;
if ((fTint<=2000.0)&&(fTint>100.0)) dIncValue=100.0;
if ((fTint<=200.0)&&(fTint>20.0)) dIncValue=10.0;
if ((fTint<=20.0)&&(fTint>=2.0)) dIncValue=1.0;
if ((fTint<2.0)&&(fTint>0.2)) dIncValue=0.1;
if (fTint<=0.2) dIncValue=0.01;
SetCtrlAttribute (hMainPanel, MAINP_INTTIME, ATTR_INCR_VALUE, dIncValue);
break............
-------------------------------------
Adding events like
case EVENT_COMMIT:
case EVENT_LEFT_CLICK:
case EVENT_VAL_CHANGED:
GetCtrlVal(hMainPanel, MAINP_INTTIME, &fTint);...
doesn't help.
Swallowing events after setting of the attribute like
SetCtrlAttribute (hMainPanel, MAINP_INTTIME, ATTR_INCR_VALUE, dIncValue);
return 1;
doesn't help.
This stuff -
ProcessDrawEvents();
ProcessSystemEvents();
doesn't help also.
Any other suggestions? :/
I just received a book from ASAM that lists members and products. There is a page for NI in this book and it lists the following (among others):
NI LabWindows/CVI
Type ANSI C blah blah
Functionaties blah blah
ASAM Standards ASAM MCD-1 CCP, ASAM MCD-1 XCP, ASAM MCD-2 MC (ASAP2/A2L), ASAM MCD-2 NET (FIBEX)
I just searched this board from information on using ASAM (in my case ASAM-3MC), and nothing turned up. I have written a library in Visual Basic .NET, but I need to port this over to LabWindows CVI.
Just what does NI have to offer for ASAM that works with LabWindows/CVI?
P.S. My software need only commmunicate with the ASAP server, not the ECU itself.
Hello,
Is there a way to retrieve the constant panel ID of a panel that was loaded with LoadPanel ?
I can always save this value in a variable when loading the panel, but I would have expected a better solution.
Thanks

Hi,
I've encounterd an issue which I'm trying to end a thread from another thread
I have one main thread that calls two different threads (Thread1 & Thread2) as so:
Thread1()
{ ... while (g_ThLoop) { ...Do stuff... } ...Cleanning memory etc....
}
Thread2()
{ g_ThLoop = 0;
}
MainThread()
{
.... g_ThLoop = 1; CmtScheduleThreadPoolFunction (DEFAULT_THREAD_POOL_HANDLE, Thread1, 0, &hFid1); ....Do Stuff... CmtScheduleThreadPoolFunction (DEFAULT_THREAD_POOL_HANDLE, Thread2, 0, &hFid2);
CmtWaitForThreadPoolFunctionCompletion (DEFAULT_THREAD_POOL_HANDLE, hFid1, 0);
CmtWaitForThreadPoolFunctionCompletion (DEFAULT_THREAD_POOL_HANDLE, hFid2, 0);
CmtReleaseThreadPoolFunctionID (DEFAULT_THREAD_POOL_HANDLE, hFid1);
CmtReleaseThreadPoolFunctionID (DEFAULT_THREAD_POOL_HANDLE, hFid2);
}I've tried to debug in debug and release configuration but the change of g_ThLoop from Thread2 doesn't make Thread1 to exit
also tried to use CmtLock, Local Variable and Safe Variable but...with no success

greetings,
i'm addressing an Ethercat device using the Beckhoff Twincat ADS dotnet library, that is linked into my project as an instrument i created.
The function in question reads an analog input into the variable whos handle i pass to it (&valueHandle1) , but also requires the variable type, of the type System_Type.
err = TwinCAT_Ads_TcAdsClient_ReadAny_1 (tc_handle, Var_handle1, UINT16, &valueHandle1, &exception);
in C# the variable type is easily passed by e.g. typeof(Uint16)
but i'm having difficulty in Labwindows. i tried passing the variable type directly, without success.
This is the function proto:
int CVIFUNC TwinCAT_Ads_TcAdsClient_ReadAny_1(
TwinCAT_Ads_TcAdsClient __instance,
int variableHandle,
System_Type type,
CDotNetHandle * __returnValue,
CDotNetHandle * __exception);
and my code is attached below.
Any help will be appreciated

Hello,
I'm new in LabWindows/CVI. Is it possible to compose a status bar, like in C#, in LabWindows/CVI? Moreover, how can I place the buttons, that I composed before, onto the tabs or decoration tools?
Good days...
I'm starting my exploration of network variables (CNV) with the example projects. Excellent examples.
Using the Polling project, I have the writer program running on one PC. On another PC, I have the reader program running. I modified it slightly so that the network path would be selectable using the Browser example project.
The Reader can't find the Writer network variable. The browser popup (where Reader is running) finds the PC that is hosting the Writer program. So this is good, in the sense that this verifies both PCs are on the same network and subnet.
But in the browser, the tree view can't find any attached network variables. This seems like a simple problem, but I can't find any.
Also, if I run the Reader app on the same PC which hosts the Writer app, this browser popup finds the network variable attached. So I know that on the same PC, Writer and Reader are working. Just not over my network (which is kinda the whole point!)
