&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I have a probelm when I use the "tool/import shared library(.dll)" wizard&nbsp;to generate the&nbsp;API from C. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The API &nbsp;works correctly when I complete the wizard, but after I exit labview and re-start labview to run&nbsp;the API&nbsp;again.

&quot;re-entrant&quot; &quot;file I/O&quot; &quot;QSM_State Machines&quot;
&nbsp; &nbsp; I have trouble with writing (appending) to text file in a QSM that is in an "occurence mode" of operation whereby the queue waits for outside engueue to go ahead and do a task. The task is simply to write to a file a line of text. &nbsp; Outside producers give the queue its go ahead and data is sent along etc... &nbsp; WHat I am seeing in the logging functions are multiple errors (Error 1) Somehow Labview&nbsp;is not noticing that the reference is valid or it is invalidating the reference. &nbsp; Q is Should I just let the QSM loop to keep it alive and would that work? &nbsp; What is the rule concerning queue waiting for an event? Does the VI get flagged as idle and is that why the ref appears to be dropped?&nbsp; THere is no reason I can think of for the ref to be dropped. It is opened in the init frame then kept in a shift register. and available at each iteration in the QSM. &nbsp; The example works in a simple loop but not a loop that is waiting on an occurence.&nbsp; Why? &nbsp; The only work around I can manage is to use the path and open the reference when it is not valid which feels kind of&nbsp; silly if you get my drift &nbsp; Anyone seen this before? &nbsp; Thank You &nbsp; &nbsp; &nbsp; ...

Adding an &quot;IMAQ Image.ctl&quot; to the &quot;Display State.ctl&quot; of an XControl prevents LabVIEW from creating a probe of &quot;Display State.ctl&quot;
I am working on an extended IMAQ Display control using LabVIEWs XControl capabilities. &nbsp; I need a copy of the original image passed to add some overlays which must not affect the original image. To achieve this I am creating a backup image in the "Init.vi" and deleting it in the "Uninit.vi". I am storing the reference&nbsp;of this image&nbsp;in the "Display State.ctl" which is part of every XControl. &nbsp; As soon as I am adding an "IMAQ Image.ctl" to the Display State cluster, it is no longer possible to generate a probe of the Display State cluster for debugging purposses. I am always getting the message: "Failed to load or create probe." Deleting the "IMAQ Image.ctl" from the cluster makes the probe working again. &nbsp; Is it a bug or am I doing something wrong? &nbsp; I am working with LabVIEW 8.5 and Vision 8.5. &nbsp; Regards &nbsp; Ingo Bartsch Hello Mr. Bartsch, is it possible for you to post a small example to reproduce the behaviour?

How can I modify the &quot;Type definitions&quot; of &quot;Function Prototype&quot; if I want build a DLL in Labview 8.5.1.?
Hello,We have a library with several VIs (API - Interfaces to our Real Time Target). This VIs we provide to our customer to generate own VIs to control the Real Time Target.Now we want to provide the functionality of this VI-library as DLL to our customer. The problem is, that labview use self definite name of type definitions. Also if I use "strict Type definition".Example:void GetOutputValues(VARIANT *Scale_In, int32_t ModelNr, uint16_t SignalID[], TD1:smileymad: *errorIn, VARIANT *Scale_Out, TD2 *Data, TD1 *errorOut, int32_t len)It is possible to modify "TD1" and "TD2"? I want to give useful names.GreetingsSteffen Hi Steffen, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Try&nbsp;editing the .h file as follows: CHANGE FROM: typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} TD1; CHANGE TO: typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} TD1; typedef struct {&nbsp;LVBoolean status;&nbsp;long code;&nbsp;LStrHandle source;&nbsp;} LVErrorCluster; then your GetOutputValues prototype becomes: void GetOutputValues(VARIANT *Scale_In, int32_t ModelNr, uint16_t SignalID[], LVErrorCluster *errorIn, VARIANT *Scale_Out, TD2 *Data, LVErrorCluster *errorOut, int32_t len) If your source-code doesn't refer to "TD1", then&nbsp;you probably won't need to keep the TD1 prototype!

How to define &quot;byte stream type&quot; for &quot;open file&quot;?
Hello, I created some numbers (type "double") in Matlab and stored in a file. What value should I use to specify the "byte stream type" for "open file" in Labview? Should I put something like "DBL" or "I32". I don't know where to find the list of legal "types" in Labiew help. Thanks so much! Felicia Looks like 7.1:<img src="http://forums.ni.com/attachments/ni/170/347924/1/read%20file%207.png"> The Matlab "double" is 64 bits (8 bytes). It doesn't make much sense to use an integer datatype to read a floating point value, so you would use DBL in LabVIEW. The numeric data types table can be found <a href="http://zone.ni.com/reference/en-XX/help/lv/71/lvhelp/Numeric_Data_Types_Table/" target="_blank">here</a>.

&quot;Save measurement to file&quot;-VI doesn't obey the &quot;Use next avaible file name&quot; setting
I'm using this express VI to store data. In it's properties, there's the "If a file already exists: Use next avaible file name" radio box which does not work.

&quot;Re-Chunking&quot; A labview waveform per iteration.
Hi, &nbsp; I've got a quick question, so say I've got a DAQ Block, that captures a signal at 300 Samples/Sec. So for every iteration of an outer while loop I get 300 Samples Per Second. Now I want to do some signal processing where, for example in a for loop inside the while loop, where I look at the samples for that second in chunks of X (we'll call it 10) samples per second. Is there some way to "Re-chunk" a waveform over iteration like this?Regards,Kenneth Miller You probably don't want to have that for loop doing its re-chunking inside your DAQ while loop.&nbsp; You could take your data out of the while loop using a queue and then re-chunk in a data processing loop.&nbsp; Or if the re-chunking is not time critical you wait until all your DAQ is done and then re-chunk from file (or array in memory).&nbsp; I dont know if that is helpful to you or not.

Kenneth, You can convert the DDT to a Waveform data type.&nbsp; Then you can get the waveform components, (t0, dt, and Y).&nbsp; Depending on what signal analysis you are doing, you might not even need to do this.&nbsp; But, then you can build the waveform with the values ...
