I would like to install the Labwindows CVI in NI cDAQ-9133 and some errors occur, for example, it lacks DAQmxIOctrl.fp or verify that you have access to that directory. So I tried to reinstall the NI-DAQmx. And there are still some errors as the attached picture shown.
Could anyone help to solve this problem? Thanks in advance.
I am working on a project to acquire data from an NI-9205 and transmit results to a server. During some initial testing of the code we are seeing a random crash of the program with the following message:
NON-FATAL RUN-TIME ERROR: "DAQmx4.c", line 99, col 9, thread id 0x00001338, function id 105: Function ConnectToTCPServer: (return value == -11 [0xfffffff5]). Timeout error
Why is the program stopping for a non-fatal error? Particularly a timeout - that's the whole purpose of having a timeout in the first place - to keep the program running.
How do I prevent the program from stopping like this for any non-fatal errors?
I would like to add the capability to acquire video from an Axis camera, and I understand from previous conversations with tech support at NI that this is possible with the Vision Acquisition Software included in my NI software package.
Can anyone suggest a good place to start with examples and documentation for using Vision Acquisition Software in Labwindows to capture video?
Hello,
I have some performance issues with application build in labwindows CVI 2012 (64bits).
With time SetCtrlAttribute functions are taking longer and longer, and the application become unresponsive.
CPU and Memory consumption are OK.
Target OS is Windows Server 2012R2. (Runtime 2012).
Is there any known issue relative the this OS ? Should i upgrade to runtime 2015 ?
Best regards, G. Lacroix

Hello,
We have been using a program written on 2010 LabWindows CVI and Windows XP environment. We now getting new computer with Windows 10.
Can we use the same program?
I tried to generate a 64-bit version and build a new release. But I get an error message
saying
"dataskt.h" The LabWindows/CVI DataSocket library is not supported on X64
Thanks

On an oscilloscope there is usually an indicator that shows what portion of the capture buffer (sometimes called a viewport or a window) that is currently being displayed. I talked with NI and they don't have any numeric slider that behaves the same way. I am looking for ideas on how to do this.
Thank you

I have a GPIB/USB from keisight 82357B.
What are the libraries that I have to install to make it run in labwindows?
Thanks
Hi,
I'm relatively new to CVI, but I'm in need of some help. Right now, I'm creating a UIR with a user input with a text box that is querying a database full of data. I'm wondering how do I get what I entered into the textbox into the WHERE OPERATOR = ' USERS INPUT '. Also, I'm trying to print that SQL Statement out too. So, far I'm just trying to get the output of this simple SQL statement.
hstmt =DBActivateSQL(hdbc,"SELECT * FROM REG_RESULTSTABLE");if(hstmt <=0){ShowError();}
sprintf(uutNum,"%s \n",hstmt);while((resCode =DBFetchNext(hstmt))== DB_SUCCESS){SetCtrlVal(panelHandle,PANEL_lstregulator,uutNum);}
It seems that the documentation for AddCtrlToSplitter() function is incomplete and/or partially worng.
This function attaches a new control to the splitter control.
First of all, it's not clear if parmeter controlID refers to the splitter or to the control to attach.
From my tests it seem that this is the splitter control.
Second point: parameter controlToAttach has no description.
Based on its name, it seems that this is the control to attach 
Could someone from NI side clarify and improve the documentation?

Maybe this is a stupid question, but is there a way to get the value of a control attribute that has been set in the uir?
I try to explain better with an example.
Hello everyone,
I want to use the USB-5856 board for my application "with inductive input sensors and actuators such as pneumatic output valves".
I need to know if Advantech products can work with labwindows? cause i didn't find the driver.
I created a new control using
int control = NewCtrl (panelHandle, CTRL_ROUND_LED, 0, y, x);
and then I drew a line using the same coordinate (x,y) using the code below.
I expected the cross hair lines to be at least near the newly created LED,
but they are not. They are far away. The CanvasDrawLine(), I think
is using the top-left as the origin. The NewCtrl() seems NOT.
How do I reconcile the coordinates used in CanvasDrawLine() and
NewCtrl() functions.
Point start, end;
start.x = x - 50; end.x = x + 50;
start.y = y; end.y = y;
CanvasDrawLine(panelHandle, canvas, start, end);
start.x = x; end.x = x;
start.y = y - 50; end.y = y + 50;
CanvasDrawLine(panelHandle, canvas, start, end);
Hi,
I am trying to create a program that allow me to copy files from usb connected camera to local directory in PC.
The traditional functions like GetDir() or SetDir() or DirSelectPopup() is not working because the camera folder is not mapped as any drive.
May somebody can help or send any example how to see the files (Pictures) in a camera.
Thank you very much

Whenever the computer reboots or ethernet cable connecting to cDAQ-9184 is unplugged and re-plugged, my Labwidows application generates an error attempting to communicate with it apparently.
The error I experience is DAQmxCfgSampClkTiming ERROR: specified operation cannot be performed when there are no devices in the task.
The only way to get the cDAQ-9184 working is to open up the Measurement and Automation Explorer and select the cDAQ-9184 and self test it to get it connected.
How can I fix this problem so on a reboot or reconnection of the ethernet cable my Labwindows application can connect to the cDAQ-9184 without having to use MAX?
Hi,
I'm currently programming a SQL statement with DBBindCol... I'm getting either ASCI characters out or garbage characters. I'm wondering if there anything special I need to do to make sure it reads the right variable I selected in the statement. Are the two pointers just to show the address of the variable I selected. If so, what does DBFetchNext(hstmt) do? I get an error everytime I run it. Thanks!
Below is a sample of what I'm trying to do:
hstmt = DBActivateSQL(hdbc, "SELECT TESTINDEX,SESSIONID,OPERATOR,SN,TESTDATE,TEST_TIME,ERRNUM,ERRDES,SYSNUM FROM REG_RESULTSTABLE WHERE SN = 260887");
if(hstmt <= 0)
{
ShowError();
}
int nrec = 0;
nrec = DBNumberOfRecords(hstmt);
if(nrec<=0)
{
ShowError(); /*goto Error;*/
}
resCode = DBBindColInt(hstmt,1,&Test_Index,&T_Index);
if(resCode != DB_SUCCESS)
{
ShowError(); /*goto Error;*/
}
while((resCode = DBFetchNext(hstmt)) == DB_SUCCESS)
{
sprintf(TI,"%d \t\t\t",Test_Index);
SetCtrlVal(panelHandle,PANEL_lstregulator,TI);
}
Hi, im working on a project where i have a list of arrays that define a current value. I have a sub-vi that reads the the values of the array and increments the index every 100ms and writes it in a global variable. the main VI only reads the value of the global variable. The problem is only the last value is read because the Sub-VI never exists the timed loop so the main VI never reads the global variable until the timed loop stop condition is met. I need a solution that makes the main VI able to update the global variable value each time the value changes inside the sub_vi.
Thanks in advance
Hi everyone,
I'm using Advantech USB-4704 as a replacing card for our current A/D card which has gone EOL.
Advantech is only "officially" supporting LabWindows, but since they have ANSI_C examples, I have been looking into them.
Except for one line, which i replace everything else seems to be supported:
//wcscpy(devInfo.Description, deviceDescription); strcpy(devInfo.Description, deviceDescription);
The code runs perfectly using Visual Studio 2017, but not CVI 2015SP1.
Could someone help me out to get this to work with LabWindows?
Or is there another approach that is better? Thinking of maybe wrap the example that builds in VS2017 and export the DLL to CVI?
I have attached both VS2017 and CVI example, where one works and one fails.
You would need to install Advantech SDK to make it work, I assume (http://downloadt.advantech.com/download/downloadsr.aspx?File_Id=1-1MENNIH).
Thanks
