Hello everyone, I hope you are well.
In fact the purpose of my duty is to put the strom in a form of a pause in other words the strom must be equal to 0 and I must bring out the different curves. I'd like to know how to do it right if I have to use a vergleicher or what?
Can someone help me because I'm really blocking thanks for your understanding.

Software trigger
Background:
I am writing C code and calling the DAQmx API directly. I am developing in VS community 2017 with the latest DAQmx. I am using the Synch AI-AO example with success. I changed the examples triggering scheme to have the AO task trigger the AI task with success. I have a PXIe chassis with a PCIe-6358 board.
Question:
I want to trigger the AO task from a DAQmx function call, a software event is going to start the AO/AI in one-shot mode. I tried DAQmxSendSoftwareTrigger() with no success. Is this idea even possible?
Thanks,
Ed

Can you change order of digital input lines with DAQmxCreateDIChan?
Hi,
I am not sure if this should be here or in the DAQmx forum. I have an application reading and writing digital lines on a USB-6281. Is it possible to change the order of the digital lines read.
DAQmxCreateDOChan(taskOut, "Dev1/port1/line1","DigIn1", DAQmx_Val_ChanPerLine);
DAQmxCreateDOChan(taskOut, "Dev1/port1/line0","DigIn0", DAQmx_Val_ChanPerLine);
So when I read using
DAQmxReadDigitalLines(taskOut, 1, 0.010, DAQmx_Val_GroupByScanNumber,
data, 16, &numRead, &bytesPerSamp, NULL);
data[0] is from line1 and data[1] is from line 0?

Not Finding Visual Studio Conversion Wizard
Based on the steps in this thread:
I installed VisualStudio 2008 (Pro Edition, not Express), then re-ran installation of LabWindows/CVI 8.5.1 directly from CD-ROM. While installing, the only option I had for a Visual Studio Wizard add-on was for Visual Studio 2005. I DID make sure this was selected. I was hoping despite the version mismatch, this would all just "work", as I understand support ran through VS2008. However, I have no option for launching any kind of conversion wizard from VS2008 when I select "New>Project". Do I need to update to a later version of CVI that offers a wizard for VS2008 as part of the install? Or should I install VS2005?

Communicating with the Preprocessor
CVI 2017, Windows
Is there a way to send something to the preprocessor from the outside world upon application build?
I am using some of the same source code files for two applications which use the same hardware. The two applications have different .uir, and thus different .h files for the UIRs. I need to tell the preprocessor to use either UIR1.h or UIR2.h for the build, based on something.
Before I dump a lot of detail here regarding multiple .h files, and communicating between these files, does anyone have an idea to solve the above.

debug executables flagged as malware?
My company uses Symantec anti virus and this morning I was greeted with a bunch of my debug EXEs being flagged. Is there anything I should know about here? I doubt these are actually suspect files; most are from the example projects.

labwindows / cvi project
I have a WINDOWS NT system in which a CVI project is running, the project checks all the module in the starting if it is ready or not? right now one module is gone bad so is there any option to copy that program and run it on a different computer using a Vmware so that I can edit it to skip the initial checks and run it?
Thank you in advance

CVI 2019 - Editor Whitespace Cursor Behavior
In CVI 2017, you could cursor around all over the editor screen.
In 2019, you can only place the cursor where characters (including spaces, tabs) exist.
So say you enter a new line, you can't cursor over to the spot you want to start typing, you have to fill the area with tabs or spaces.
Is there a way to change this behavior back to the 2017 version (and like all other test editors I've ever used for 35 years). It's killing my productivity. Going to have to go back to the 2017 editor if this can't be changed.

#ifndef macro switching
I'm making a library for a GPIO device. This device has several macros for constant values. I'm attempting to make these replaceable inside the host application that attaches my library.
For instance:
Library
#ifndef LABJACK_CLOCK_BASE #define LABJACK_CLOCK_BASE LJ_tc4MHZ #endif #ifndef LABJACK_CLOCK_DIVISOR #define LABJACK_CLOCK_DIVISOR 14 #endif
...where LJ_tc4MHZ is itself a declared long value in the vendor header.
Now up one layer from here, my host application will set this macro to a relevant value:
#define LABJACK_CLOCK_BASE LABJACK_tc48MHZ_DIV
But what I'm finding is that the CVI compiler is making two different values for LABJACK_CLOCK_BASE! I was assuming that the compiler makes the determination of the value at the beginning of compilation and then substitutes all references of the macro everywhere. Not so!
I'm sure this is convoluted, but is there a more elegant way of going about this?

How to lock folders with labwindows CVI

I have application with several folders like :

----------------------
The main folder contains several folders, so I would like to know if it possible with labwindows CVI to develop a program to lock and Unlock folder " Exemple : lock => Folder_01 and Folder_02 , Unlock ==> Folder_03 and Folder_04 "
these folder contains our sequence test that is developed by CVI.
So if there is some command or instruction to use to develop this programme ,
Thank you in advance .

Could not understand lines in "visa.h"
Hi, recently I am starting to use LabWindows/CVI 2017 as my primary coding tool. Before this, I use LabVIEW a lot and also has some experience with ANSI C programming. I read the "visa.h" file but could not understand two lines (line 88 and line 89):
typedef ViStatus (_VI_FUNCH _VI_PTR ViHndlr)
(ViSession vi, ViEventType eventType, ViEvent event, ViAddr userHandle);
This typedef statement does not look like a regular typedef statement. In the above statement, what is typedef-ed to what? Thanks.
