How to pass the Visa Resource Name parameter to labview dll in labwindows/cvi
Hello world
I build a dll of labview, the prototype is: double getchannelpower (double f, uintptr_t * VISAResourceName);
I don't know how to go from VISAResourceName to this function.
Is it related to the ViPSession paremeter in function viOpen(REES ViSession, rn ViRsrc, ViAccessMode am, ViUInt32 ti,ViPSession vi)?
BRs,
lotusky
Hey, guys:
I figured out how to pass the parameter.
In labview, you must replace the control of visa with string control. In this way, the generated dll function at the entrance of the string type.
I hope this will help others!

You have entered the value of the process request

Hi good day to everyone!
I am a beginner to LabVIEW, and currently I'm testing on a single project.
Store device data in Server series of STS (which has 16 com ports).
But I need to use 7 series STS server com ports. I need to read that data 7 com ports and save in a file.
Each com port has a different function (for example the reading of data or display).
My question is,
(1) VISA resource name operation function for 7 com ports at the same time to a VI?
(2) how can I choose different com ports to different functions?
Kind regards
Control of resources of e/s of VISA will show you all the com ports you have on your computer.
So you just need to make 7 copies of that control and the value of each of them to another com port and use for each VISA entry and read the series of functions that you do. (Have you looked in the example Finder to get examples of serial port?)

Hello
I have a control "VISA Resource Name" on my front, according to the guidelines of the attached screenshot, which should automatically fill with the names of all the VISA resources that the PC can see.
Is it possible to get a picture of these names as strings (via a property node, or other) programmatically?
Thank you very much
Dan
In the schema click Instrument of e/s > VISA > VISA advanced > VISA find resources. This VI returns an array of strings. You can type cast the string in a resource VISA type.

A control "VISA Resource Name.
In LabVIEW, there is a control "VISA Resource Name" which lists all the VISA resources, is automatically updated when devices are plugged or not plugged in and has a navigation feature.
With CVI, you can use NIDAQmx_NewDeviceCtrl () on a control of the chain, but it lists only the DAQmx resources.
There is another function that I can use to have all resources VISA listed?
Hey Vix,
It seems to be the only solution. Here you will also find an example.
I hope that helps!

How to pass the ObjectType as input for search criteria
Hi all
I have the search function that takes input parameters and returns all matching rows. It is only forward. My problem is to have several types as an input parameter. This is the reason why I'm not able to pass the value of entry for these types.
My Input Type table looks like this.
CREATE OR REPLACE TYPE T_T_PARTY_REQUEST_CRITERIA
AS THE T_O_PARTY_REQUEST_CRITERIA TABLE;
/
CREATE OR REPLACE TYPE T_O_PARTY_REQUEST_CRITERIA
AS AN OBJECT

REQUEST_TYPE_CLASS_NAME VARCHAR2 (50).
PARTY_KEY_IDENTIFIER T_T_PARTY_KEY_IDENTIFIER,
ADDTN_IDENTIFIER_INFO T_T_ADDTN_IDENTIFIER_INFO
)
/
Finally the two entries are type again.my question is how to pass the values of these two T_T_PARTY_KEY_IDENTIFIER and T_T_ADDTN_IDENTIFIER_INFO. I defined the last two types now.
CREATE OR REPLACE TYPE T_T_PARTY_KEY_IDENTIFIER
AS THE T_O_PARTY_KEY_IDENTIFIER TABLE;

PARTY_KEY_TYP_NM VARCHAR2 (50).
PARTY_KEY_VALUE VARCHAR2 (50)
)
/
CREATE OR REPLACE TYPE T_O_ADDTN_IDENTIFIER_INFO
AS AN OBJECT
(
ADDTN_INFO_KEY_TYP_NM VARCHAR2 (50).

ADDTN_RQST_VAL_DT TIMESTAMP (6).
NUMBER OF ADDTN_RQST_VAL_NUM (19: 2)
)
/
I glued the request my function here. When I pass the value null in the entry for these 2 types my query works. otherwise, it's say no valid Identifier.First I tried with the first Type.
I am passing the value that
(PRKYTP. PRTY_KEY_TYP_NM = ITTPRC. PARTY_KEY_IDENTIFIER. PARTY_KEY_TYP_NM OR ITTPRC. PARTY_KEY_IDENTIFIER. PARTY_KEY_TYP_NM = 'ALL' OR ITTPRC. PARTY_KEY_IDENTIFIER. PARTY_KEY_TYP_NM IS NULL).

How to pass the session IMAQ to the Subvi
Hello
My experience with LabView is neither very good nor extended. I am a scientist and I'm with IMAQ data acquisition. My current problem is that the people who wrote the script is modular, versatile, or clear initially structured. So I try to reduce the ridiculous number of tests in a simple flowchart to a level that people can actually understand it... and to make the more versatile script for future experiments.
I'm introducing quite a few subVIs to be executed repeatedly. However, I can't know how to pass the IMAQ session on the Subvi. I constantly get the error messages. In this case, I want to acquire images with OIDE_CollectFrame.vi controlled by OIDE_TrialPhaseCollect.vi. I couldn't understand how to assign the refnum IMAQ session class, either.
It is probably a newbie question, but usually I program with LabView.
