ECU Measurement and Calibration Toolkit 2.3 - ReadDAQ() Problem
Hi all,
I have a very specific problem with the functionality of the NI ECU Measurement and Calibration Toolkit 2.3
I am communicating via XCP to an ECU device and reading some measurement values with a defined sampling rate. Everything is working fine so far.
I use the mcDAQInitialize() and then the mcDAQRead() in a loop to get continously some values from my ECU.
I can see that normally after using mcDAQRead() , the amount of "mcPropDAQ_SamplesPending" is -1, which means that all data read from ECU.
But suddenly the DAQ functionality runs crazy and reads a lot of non-existent pending messages, also the "mcPropDAQ_SamplesPending" property is over 1.000.000 pending samples.
My problem is that with another software all values can be read constantly over XCP, so the ECU and the XCP communication seems fine.
Has anybody an idea for a solution with the rise of samples or a similar problem with the NI ECU Measurement and Calibration Toolkit 2.3?
Thanks in advance!
Best regards,
Simon

CVI2015 and color preferences
Hi,
I changed the color preferences of CVI2015 from the menu 'Options>>Colors...' but part of the window 'Variables and Call Stack' doesn't takes the background color that I set.
How can I fix it?

CVI nonstandard rs-232 baud rate
I am trying to use an RS-232 comport using a non-standard baud rate. Is it possible to send data at 2344 baud. when the stop bit is received switch to 4800 baud to receive data on the ? From post I have read users indicate the comport driver will interpet this non-standard baud rate. Will it keep it at 2344 or will it round up/down?

scan with unsigned long long
Hello,
I want to use the Scan function with an unsigned long long, but i don't found the format modifier to used to this type.
With sscanf, it's OK :
char rdBuf[1024]; unsigned long long frequency=0; sprintf(rdBuf, "33500000000000"); sscanf(rdBuf, "%llu", &frequency);
Thanks

TerminateExecutable does not terminate Microsoft application.
I have a short program that is supposed to startup a powerpoint slideshow using
LaunchExecutableEx (fileName, LE_SHOWMAXIMIZED, &g_exeHandle)). That part works.
When i try to terminate it using TerminateExecutable (g_exeHandle); Nothing Happens.
Afterwards i have: status= ExecutableHasTerminated (g_exeHandle); It returns a "1" saying that it did terminate.
Note that I placed that same line of code after the LaunchExecutableEX and the status was "0"
How can I kill the application?

mscorlib
I have a .DLL that uses mscorlib in Labwindows/CVI 2013 SP2. We recently had to update the dotnet from version 4.5.1 to 4.5.2 but in addition to the update, 4.5.1 was scrubbed from the machine. My .DLL is broken now and reports error 17502 when executed from TestStand. Stepping into the CVI code, one of the library function calls is returning a null pointer. This .DLL does work on a machine that always that 4.5.2 on it from the start.
I tried removing both the instrument mscorlib and the function panel(FP). Then reconnecting them. I tried removing the #include and letting the compiler auto add it. I tried adding mscorlib2.fp and making sure I added the mscorlib2 instrument(that is mscorlib version=2.0.0.0). Still not working. I know there is a setting in a labview .ini that tells it which version of dotnet to use. Is there something similar in CVI?

CVI using imaqCalibrationSetAxisInfoByReferencePoints
Dear all,
did anybody ever used the NI-Vision function
imaqCalibrationSetAxisInfoByReferencePoints()
in Labwindows / CVI?
It seems that the function requires a calibrated image.
Now, I do have one but I get the error
The source/input image has not been calibrated.
At least I guess that my input image is calibrated, since I use before:
imaqLearnCalibrationPoints()
Any hint appreciating,

timer control issue under Windows 7, from CVI 2013 under XP
I have a program that runs well under Windows XP. Two of the subwindows of this program use control timers @ 1Hz to determine if data isn't received from the ADC. When I launch the program under Windows 7, it seems to operate fine until I try to open one of these two windows. The timers appear to bung up the works and the windows can take up to 20 seconds to respond to a mouse click. I put a printDebugf() statement in the timer callback and it prints perhaps once/5 seconds and often hangs up for long periods of time. Any ideas would be appreciated.

GPF error on picture ring with Ctrl+Home keys
I am facing a strange behaviour while upgrading an application of mine, with GPF error occurring when I press Ctrl+Home keys with focus on a picture ring:
The address location remains the same all times when I work within the IDE; when I create the executable the error message does not show but the program crashes.
In system event viewer I see the following record that points to the runtime engine:
Nome dell'applicazione che ha generato l'errore: #######.exe, versione: 33.3.0.0, timestamp: 0x58a77f5d Nome del modulo che ha generato l'errore: cvirte.dll, versione: 15.0.1.239, timestamp: 0x57636f1f Codice eccezione: 0xc0000005 Offset errore 0x0010100d ID processo che ha generato l'errore: 0x2054 Ora di avvio dell'applicazione che ha generato l'errore: 0x01d28970f82e4fbd Percorso dell'applicazione che ha generato l'errore: C:\############.exe Percorso del modulo che ha generato l'errore: C:\Windows\system32\cvirte.dll ID segnalazione: 407fae2c-f564-11e6-8305-00c2c6885ebd
I stripped down the application to the minimum sample program attached that exhibits the behaviour. While doing so, I found that a similar error occurs if I operate the picture ring in the UIR editor, but with a more serious error that crashes the IDE:
It seems to me that only Ctrl+Home key combination is critical: I attempted other combinations without problems (Ctrl+I, Ctrl+End, Ctrl+Enter, Ctrl+Fx keys...).
Anybody has some clue to address this error?
I'm currently working on a Win7Pro machine with CVI 2015SP1 installed.

hide warnings from external files
Hello,
Compiling my project, I receive lots of warnings from .h files that are delivered with CVI or other modules.
I'd like to focus on "my" warnings but they are in the flow and I can miss some.
Is there a way to say clang compiler (or CVI interface) to hide the warnings from files not in the project directory (#include <thefile.h< as eg)?

Table Control
Hello,
I'm trying to build a program in which I have a table and the user can click on whichever radio button he wants and it will add the corresponding array to the table.
My arrays are created at the beginning with an arbitrary amount of memory (which is larger than expected to be loaded) and a for loop while loading the file counts the actual number of elements in the file itself. I wish to use SetTableCellRangeVals to put the data in rows since the data is not uniform. Does the array length has to match the number of rows I open even though I explicitly define how many needed rows to put (the array itself is longer than the amount of data I want to put in the table)?
Thanks in advance for the help.

Plotting real time graph
Hello,
I want to develop labwindows CVI application where I get continous real time plot of data. I used strip chart for that. I made X axis as relative time , absolute time etc. I am getting plot correctly, but x asis labelling is not correct. Time may not have been passed 1s , but x axis labelling shows 299s and all. Please tell me correct setting to get correct time in x axis same as our real clock.

Watchdog signal handle
Hello everybody,
I have a question about a reading a signal with a digital input. I would like to handle a watchdog signal that I get from a higher level system. The watchdogs signal works like a heartbeat. Is there a failure with the system in the higher level my system should notice that. The watchdog signal is a square-wave-signal (0,1,0,1 etc.). At the moment I do not now the frequency. The plan is that when the signal stands by 0 or 1 to wait two seconds. If there is no reaction after two seconds the program should stop because the high level system has an error.
Has someone a idea how I can implement this feature? For me it is important to know how I can do the signal acquisition correct.
Best regards
