How can i go about this ?
Any suggestions

Re: not enough memory to complete this operation
Hi Sowjana,
again I moved your message from an old thread into your own one…
when i tried to plot the multiple channel data by using array it showing not enough memory to complete this operation How can i go about this ?
When you get "out of memory" then the waveforms are too big. What is the size of your TDMS file? How many samples do those waveforms contain?
Solution: read only parts of the whole waveforms to plot them…

Unable to communicate in NI MAX. I have attached the LabVIEW coding (This coding is download from NI, but unable to communicate with TDS3032C)

Re: properly start FPGA lvbitx
ok, thanks, will try tomorrow. There has to be a simple solution.
Guess when I deploy, it stops the cRio, then loads all vis into voilatile memory, thats why it works. Cannot remeber the name, put all the vis in memory, select startup vi, set lauch startup.rtexe false, see how that works.

Re: TCP TRANSFER DATA
Sorry, another question.
If i want to tranfer a control, how can i do this? because , I'm trying to do this with the solution that you gave me, but it's not valid to transfer control.
Thanks.

Re: TCP TRANSFER DATA
What properties (value, Label text, Description text etc.) of your control do you want to transfer?

Re: TCP TRANSFER DATA
I want transfer de value of my controls, almost all my controls are dbl type, except 2 that they are u8 type.
Thanks.

procesamiento de imagen tomada con webcam
Buenas estoy haciendo un projecto que trata de un laberinto donde una bola es detectada a travez de una camara web y tiene que moverse a traves de dos servo motores (PWM y PID). Mis preguntas son las siguientes:
1) como puedo hacer para quitar el brillo de fondo creado por la lampara que coloque para aumentar la luminosidad y asi evitar los cambios de luz exteriores. La bola es perfectamente detectada menos donde se encuentra el reflejo de la lampara. he utilizado el vision assistant y adquisition. 2) tienen otra idea de como evitar esos cambios de luces?
3)mi webcam produce max 30 franjas por segundo y el VI requiere 100ms para procesar cada imagen, es verdad que con el modulo de FPGA se procesaria mas rapido? necesitaria una camara mas rapida?

Re: Stored Procedure call with multiple input and output parameters
Hi, I use this setup with procedure calls on an MS-SQL-Server:
But I'm using only the directions Input & Output.
The string "SQL procedure call" has the format:
{?=call PROCEDURENAME(?,?,?)}where the number of questionmarks within the parantheses equals the number of inputs & outputs.
Jens
EDIT: The FOR-Loop is not necessary. It is there to repeat the procedure call once in case of an error.

Re: TCP TRANSFER DATA
My goal is following:
I have three .vi one in FPGA , one in Host-target and one in Host-computer and I want handle all program from the computer, and in this .vi i want to change the control for they'll change in target (host and fpga), so that, I want see the controls and indicators in conputer (server)

Re: ULx in LabVIEW - Error 10023 occurred at ULx Create Channel (AI-Temperature).vi:2950001
You have to get ULx from Measurement Computing as part of the MCC DAQ CD, from here: https://www.mccdaq.com/Software-Downloads
It looks like the current version of ULx is 2.22, part of MCC DAQ CD 6.60, released last September. You might try updating it and see if it makes any difference.

Re: TCP TRANSFER DATA
Hi Cristina,
did you create an example project for your PC host/ RT host/ FPGA system?
LabVIEW comes with such examples - the communication is explained in them quite well…

Re: CSV database
the first and second point i didn't get them very well.
i wanted to append the file
and in my actual VI i'm using QMH, so i'm writing only once when i needed

Hi fung,
you surely know about this idea in the IdeaExchange…
Seems the easy way is still in development!

Re: SMTP client shows BCC recipients in sent e-mails
I have the same result using the NI SMTP client, but was successful in hiding the BCC recipients by modifying the Gmail example found here:
http://www.ni.com/example/30992/en/
I changed the 'MailMessage' property node from 'CC' to 'Bcc' and sent an email from an Office 365 address to multiple recipients, without revealing other recipients addresses.

Re: CSV database
Hi N.,
the first and second point i didn't get them very well.
You are reading the CSV file, index the first column and search for an element of this column.
What didn't you "get very well"?

Nice idea, instantly got another Kudo....

Re: TCP TRANSFER DATA
Hi Christina
GerdW is correct LabVIEW gives you the best possible start and does not expect you to start from the beginning each time. Also there is plenty of information on ni.com, check this out as an example.

Implementing API function with HWND
Hello,
I have a camera with a dll with a function to start the camera. The following is copied from the header file...
#define TCAM_EVENT_EXPOSURE 0x0001 /* exposure time changed */ #define TCAM_EVENT_TEMPTINT 0x0002 /* white balance changed, Temp/Tint mode */ #define TCAM_EVENT_CHROME 0x0003 /* reversed, do not use it */ #define TCAM_EVENT_IMAGE 0x0004 /* live image arrived, use Tcam_PullImage to get this image */ #define TCAM_EVENT_STILLIMAGE 0x0005 /* snap (still) frame arrived, use Tcam_PullStillImage to get this frame */ #define TCAM_EVENT_WBGAIN 0x0006 /* white balance changed, RGB Gain mode */ #define TCAM_EVENT_ERROR 0x0080 /* generic error */ #define TCAM_EVENT_DISCONNECTED 0x0081 /* camera disconnected */ #define TCAM_EVENT_TIMEOUT 0x0082 /* timeout error */ #ifdef _WIN32 tcam_ports(HRESULT) Tcam_StartPullModeWithWndMsg(HTCam h, HWND hWnd, UINT nMsg); #endif
Would the attached png be a proper implementation of this function in LV?
I'm lost at the 'HWND hWnd' parameter.
HTCam h is the identifier of the camera (it works in other functions).
UINT nMsg would identify one of the 9 messages (I believe).
Thanks!
Mohit.
