Change the parameter Prototype of a Module DLL TestStand Programmaticaly

Hello.

I started this post inside the LabWindows, but there was no response.

Hope I can get help here.

Please see the following link

Thanks in advance.

Hi Doug.

I'm sorry for the delay.

Here is how I solved the problem: I changed the module of the BCI to the DLL module.

Here is a sample of my code:

I changed CVIModuleGetParameters() and CVIParametersGetItem() to TS_DllModuleGetParameters() and TS_DllParametersGetItem and now it works fine.
seqContextCVI = object reference ThisContext
__declspec(dllexport) __stdcall GetControlarParameters (CAObjHandle seqContext) Sub
{
error int = 0;
ErrMsg errMsg = {'\0'};
ERRORINFO errorInfo.
char strItemLabel2 [1024] = "";
Step CAObjHandle = 0;
CAObjHandle seqFile = 0;
Module CAObjHandle = 0;
Parameters CAObjHandle = 0;
Parameter CAObjHandle = 0;

tsErrChk (TS_SeqContextGetStep (seqContext, & errorInfo, &step));))
tsErrChk (TS_StepGetModule (stage, & errorInfo & module));
tsErrChk (TS_DllModuleGetParameters (module, & errorInfo & settings));
tsErrChk (TS_DllParametersGetItem (parameters, & errorInfo, CA_VariantInt (1) & parameter));
sprintf (strItemLabel2, "\"%s\"", "TEST" ");
tsErrChk (TS_CommonCParameterSetValueExpr (parameter, & errorInfo, strItemLabel2));

NOTE: After make a change to a stage you must mark the file, as amended by
increment the number of changes to the file. It is also necessary for the change to show
upwards in the sequence editor immediately.
tsErrChk (TS_SeqContextGetSequenceFile (seqContext, & errorInfo, seqFile));
tsErrChk (TS_SeqFileIncChangeCount (seqFile & errorInfo));

Error:

CA_DiscardObjHandle (Step);
CA_DiscardObjHandle (seqFile);
CA_DiscardObjHandle (module);
CA_DiscardObjHandle (Parameters);
CA_DiscardObjHandle (Parameter);

If an error occurs, set the error indicator causes an error of execution at TestStand.
If (error<>

TS_SetStepError (seqContext, error, error);
}

Thanks for all the help.

My best regards.

  • Change the parameter [] strings in a sub - bound dynamically VI

    I'm in a situation where I need to use the sub-panels to dynamically bind subVIs for data entry. I also like having the calling VI to change the [] parameter strings several enumerations in the Subvi, but this doesn't seem to be possible, as the Subvi is not in edit mode. Does anyone know of a way around this?

    I read data from a file to initialize the enums, so that I can have the Sub - VI read the file instead, but I was hoping to do it once in the main VI and send strings to the subVIs to speed up execution.

    Thank you!

    It's impossible.  Enums are set in stone at run time.  Oh wait, you try to use the script running.  Sorry, it does not work.  Note that the property for the [Strings] node for the enum is blue?  That tells you it is a script node and is useful for mounting screws over time edit.

    As RavensFan said, you use a ring.  Their data type is a real number.

  • change the parameter db_recovery_file_dest

    Hello!

    We use oracle 10g on windows 2008r2. the flash recovery area is d:\fra. in recent months the amount of data has increased considerably, then move the fra to another (of course largest) partition/hard disk.

    now the question: is it possible to change the setting "db_recovery_file_dest' from d:\fra to e:\fra and then copy the games of backup and archive logs to the new location OR is - it enough to change the parameter and oracle knows that data before changing the setting must be placed in d:\fra? hope this is understandable... ;-)

    Thanks in advance!

    Ciao,.
    Christian

    Hello;

    Yes, you can change it and it should work fine.

    The catalogue will know on older backups, so it shouldn't be a problem.

    alter system set db_recovery_file_dest='e:\fra';
    

    No doubt it would change too: (at the same time)

    alter system set db_recovery_file_dest_size=??G scope=both;
    

    The audit is easy

    SQL>show parameter db_recovery
    

    Do NOT move the old files. Oracle will bark.

    If you want more than all of the files from an MRE old new FIU, follow the link

  • A30 - still cannot change the parameter memory

    Hi, yesterday I asked if someone could help me change my memory of graphics chip integrated 32 MB to 64 MB on my satellite A30. Sascha suggested goin to view properties and adjusting the frame buffer, but there is no frame buffer setting.

    He says that the maximum memory for the graphics chip is 64 MB on my system, so I think there must be a way to change.

    Any help?

    Hi Neil,

    As Sacha has suggested how to change your frame buffer size is: -.

    1 Control Panel-> display
    2. click on the option "settings".
    3. click on the "Advanced" option
    4. click on the tab "frame buffer".
    5. Select your desired menu frame buffer size drop-down.
    6. click on 'apply '.

    Note that you can also do in the configuration menu of the BIOS (F2 during the boot process). Change the value of the AMU to your chosen size.

    Kind regards

  • Problems for existing VM after you change the parameter VT PowerEdge 2950?

    Hello

    We have ESXi 4 installed, a number of servers windows 2003 32 bit running but need to install Server 2008 64 bit. Didn't know that these parameters were until he is tried to install 64 bit OS and got the error message. I read through other posts, but haven't seen a direct answer to this question:

    Are there any negative potential impact for my 32-bit servers existing after I enter and change VT enabled, NX enabled?

    Thank you

    cwhicks wrote:

    No.; for 32-bit Windows 2003 by default execution mode is binary translation, if VT is enabled in the BIOS.

    If your Windows 2003 guests are running with SP2, you may find that you can get better performance by changing the mode of execution to VT - x (or VT-x/EPT on systems with EFA).  Before SP2, you definitely want to stay with binary translation.

  • Definition of the parameters of the VI in LabView Action Module with TestStand API

    I started playing with the API, TestStand, and I have questions on how to configure a TSAdp.LabViewModule.

    I use a few examples of NOR and the community of developers to get started:
    http://www.NI.com/example/30263/en/
    https://decibel.NI.com/content/docs/doc-18401

    These examples work as I expect and I understand them.  I am struggling with how to specify VI parameter values in the module when the step type is 'Action '.  In other words, how to set these parameters?

    All the examples I see use of step types that have defined fields, which are accessible through the API with 'AsPropertyObject '.  The action type, by default, has the result field.

    Set the values of the parameters of a VI with the API TestSTand?  If so, how?

    Thank you

  • How to change the size of the hover in Spry Panel, but not the rest of the site?

    Hi guys, I need to add more tabs which means I need to reduce the size of the font of my style of H2 and its stationary state. However, when I set it is 10 pt in sprytabbedpanels2.css it remains 14 in live mode to view until I also change the parameter to 10 points in my Arrowmark.css file, which then shoves upward stationary behavior of links elsewhere in my site.

    Is there a way to set the hover in the stylesheet of tabbed panels and will not affect the rest of the site? Or I do something wrong?

    My site is www.wakatipucollection.co.nz/wholesale

    Thanks in advance for the help.

    JO

    Hi Jo.

    Watch out, I'm not an expert, but in my way of thinking, your CSS Spry needs link Pseudo-classes to specify a special font size so that links in your tabs. Normal size attributes H2 or the police has no effect on the text which is a link.

    This may look like

    . TabbedPanelsTabHover a: link {}

    do-size: 9px;

    }

    . TabbedPanelsTabHover a: visited {}

    do-size: 9px;

    }

    . TabbedPanelsTabHover a: hover {}

    do-size: 9px;

    }

    . TabbedPanelsTabHover a: active {}

    do-size: 9px;

    }

    You have time to try it?

  • Dynamically change the path of the report

    Is it possible to dynamically change the path where reports are saved. TestStand 4.1.1

    Glennjammin,

    You can set a path to the specific report for any sequence that you run via the entry points of process model using the reminder of your sequence ReportOptions. It will allow you to change the current settings in the Options report (including the path) for the execution of this sequence. This allows each of your sequences have unique report options.

    If I understand your question, you want to do is exactly what is meant recall ReportOptions.
