Adding units of a string, or a property

• String ActiveX Server property

  Hello world

  I am developing an application using LabWindows/CVI 8.1 on a machine WinXPSP3. To enable easy automation of functions in my application, I decided to add an ActiveX Server interface to my request and the first tests look very promising. However, after I introduced a property of type string to my ActiveX Server I get a strange error when the get method is called by the customer. The code generated automatically from the ActiveX server receives the application string and converts it to a BSTR that is returned to the client. The string pointer returned by the demand function is converted to this type BSTR and later in auto genereated the string pointer is freed with a call to CA_FreeMemory (). Generally that it works fine but when I run my application in mode Debug execution is interrupted at this point (even when there is no breakpoint) and the debug window displays the following message:

  Heap [application_debug.exe]: invalid address specified to RtlFreeHeap (00140000, 027995E0)

  In fact, the allocated memory is not released.

  I have generated a small sample project that reproduces the issue. The error occurs in autotest_axs.c on line 71, a breakpoint is set for convenience. The attached VI LabVIEW is used to serve the client ActiveX and makes the necessary calls to reproduce the effect. Simply build the CVI project in debug mode and start the VI during execution of the implementation of the CVI.

  At the moment I don't think I'm doing something wrong, maybe everyone at OR has an idea.

  Thanks in advance!

  In the AutotestApplicationget_String function in the autotest.c file, you should use the function library ActiveX CVI CA_AllocateMemory to allocate memory for the string. Instead, you use the ANSI C malloc function. This affected memory is released later by calling CA_FreeMemory call to the CaSrvrAutotestApplicationget_String function in the autotest_axs.c file. It is allocated in the memory manager and deallocated in another.

• Weird characters added to the URL string.

  So, while I use ColdFusion at work, I also use it on my personal website, where I host a blog and photos in the gallery.

  Whenever I click on a message or a photo from the Gallery, I noticed that the URL is added with a kind of token.

  For example, this:

  http://mysite/post/2224

  becomes this:

  http://mysite/post/2224#.VmKaAipG_0

  It allows for some URL channels very ugly when I paste something to someone.

  My host is using CF9 (I think) and Linux.  Is there an obvious reason that that?  I use the session management and cookies to the client in Application.cfc, so maybe that has something to do with it.

  Do you use a javascript like AddThis plugin on your website? Using firefox in seeing these links?

  I know that addthis puts params like this on the URL for analytics. -See more here what is Address Bar sharing Analytics?

• On the digital unit of string conversion

  Hello world

  I'm trying to convert a digital control with min as a unit to a string.

  The fact is that it converts in seconds before it updates the channel indicator.

  

  I noticed that the format "in channel" will convert always first to the base unit (unit multiple value of units conversion value), as W kW (10 kW will display 10000 W) to watt unit.

  Is there a way to format the entry without this conversion value to the first base unit?

  Thank you...

  If you are looking for the syntax of using LabVIEW Format specifier, you'll see a unit option.

  This is the format that you want to keep the string in a few minutes: g {min} %

• Insert a property root data in a text object

  Hello

  I am writing a script to create a default report with a variable number of pages.

  For this, I use objects DIAdem to create these new pages, but I got stuck trying to correctly configure some textbox.

  I would like to display a property of data root in all the pages, don't forget that pages are created as the script goes.  "In theory", this value is a user input (get via a DlgBox when the script runs) so what I did was to assing the value: Data.Root.Properties ("Report_Number"). The value to the new text object (by using the TXTTXT command).

  By doing this, the new report shows the value (as a simple text, no longer tied to the property) which is fine as long as the user knew this value. But here's the problem, sometimes this value cannot be specified until the last moment so that users may have to change and now it's not that simple to change the value of the property, and then click Refresh. He or she would need to go one by one in order to change this "number".

  I am looking to start a new modeless dialog box or a new buttom that opens/closes all these objects refreshing their text of values but move before I would like to know if there is something easier to keep the link between the value of the property and the text object.

  p.S. I use 11 DIAdem

  Thank you

  Javier

  Javier,

  I think that I thought about it!

  You simply send the property textbox as variable instead of just under form of text. Here is an example

  TXTTXT = "@Data.Root.Properties(""Report_Number"")." "Value".

  You can see that I added the @ on each end of the property and also quote the string so that the script he interpret correctly. I also had to quote the string Report_Number so that the VB script would interpret it correctly.

  Give that a try and let me know how it goes - I think it should work fine for you. After you run the script, I can change the property and then refresh the report and see the updated value.

• Units in the Stimulus Data Logger profile editor

  I have an active Veristand application that uses the data logger built in Stimulus profile editor. Recording data works fine but it does not display the channel units. This becomes a big problem with our client.

  I suggested to change the channel names so that they have units in them. Before we go on changing over 100 names of channel and dealing with the associated benefits of doing this, I would like to know if there is a way to get the units of the string to display in the data logger.

  Before, it was suggested, I already use the recording custom device of embedded data and I hammered him to the gills.

  Has anyone concerned with that? Don't know a good workaround solution?

  Thank you!

  We have a patch for this NI VeriStand 2011 SP1 if you have access to this version. The problem is that VeriStand using incorrect property name for the property units. Channels are registered with a property named 'Units', then it should be "unit_string" so that the other products like the tiara to interpret it correctly.

  You can apply an INI token to change this behavior in 2011 sp1. Add the token following in the file below.

  Win7:
  C:\ProgramData\National Instruments\NI 2011\NI VeriStand.ini VeriStand

  WinXP:
  C:\Documents and Settings\All Users\Application Data\National Instruments\NI VeriStand 2011\NI VeriStand.ini

  [NOR VeriStand]
  LogUnitsPropertyName = unit_string

• Public property of custom in the property panel component

  I have ready a few days ago an article somewhere on public property of component adding custom in the Panel property of Adobe Flex 3 using a few Metatag.

  Today I thought to add my custom in the properties panel component property, but could not do, I can't even remember the meaning of this article.

  Could you please guide in this matter?

  Thank you.

  See the description of Inspectable tag in docs: http://livedocs.adobe.com/flex/3/html/help.html?content=metadata_3.html

• prefixes and units of first hp

  According to the manual, if you want to use a prefix with units, you select the prefix first. When I do this (after you put a value on the line of writing, of course), the prefix is indicated in brackets in the input line and the units menu disappears which is a surprise (I expect to wait until the units have been added). After that gate again the menu units and adding units, I press on enter and get a syntax error.

  This behavior is not consistent. I just tried again and the prefix appears without brackets, the unit has hooks and I always get a syntax error.

  I tried it in input mode of textbooks (I prefer RPN, but there are problems with the use anywhere but in mode 'calculator') does not. I must be missing something but have no idea what.

  Even if I'm here, nobody knows why there is not set explicitly for calculators?

  Also (you never know your luck), if someone wrote a good guide for the first HP? Whenever I pick it up, it brings me a new problem.

  Ah, I forgot to mention that the parentheses are always required if the appliance no symbol of multiplication or division.  In algebraic entry mode, you must type the brackets yourself (if the device contains no mathematical symbols as division), so that literally, you type this:

  2_(km/s)

  The manual entry mode and entry RPN mode type brackets automatically when you press the underscore character.

• MSXML SelectSingleNode property

  Hello

  I use the MSXML in labview to read an xml file. My VI works fine. But now I want to read the attribute xsi: noNamespaceSchemaLocation from the node root with the SelectSingleNode [queryString As String = @xsi: noNamespaceSchemaLocation] property. The result is an error. If I read all the attributes of the root node, the VI does not display an error. Is it possible that labview or the property cannot interpret the ': ' (colon)? Because it can read any other attribute without a ': '.

  Thanks for the reply,

  Shavo

  Hi Hillman,

  Thanks for your help, but I solved the problem another way. I used the 'attributes' property > "nodeName". So, I get a picture of all the attribute names and I compared it with the location of schema attribute. Is there a correspondence, the MSXML to get the value of the node and it's good. I create the following XML VI with the 'selectsinglenode-colon-problem' and post it here.

  See you soon

• VISA resource name strings

  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 string that can be displayed as ASCII and hex in an indicator will allow not to store the data in a file in ASCII format

  You can see the data in an indicator very well, but when we try to write this string of hexadecimal data in a file, it will only save the data in ASCII format.

  This seems simple enough, as the indicator can be selected to display the data in different formats (VI > properties > appearance > display Style: Normal, backslash, hexadecimal).  However, I could not, for the moment save data in different formats.

  Altenbach says:

  ... or you can just read the string: text.text property to get everything that is actually displayed.

• Writing a string flattened to a Description DAQmx channel

  Hi all

  I have an application in which I have a main VI and VI configuration.  The latter configures how the façade will also look although the way in which the data acquisition system (which is driven by the main VI) will be exploited.  In the configuration VI, the user selects the channels as well as a good description of the string (which is contained in a cluster of enums, Boolean and numeric values).  I am able to write the description of each string in the description property of DAQmx channel as a string (example below) and then read the string in the back and reformat it as some type of delimited string in which I understand the structure and can decode correctly using different string functions (for example the tokenize string (, string digital, etc.).  I thought I'd get a little smarter on this subject and simply flatten the clusters to a string and write these binary strings in the description.  However, when I read this back from the description, I get error 74 - structure of memory or data corrupted.  Did anyone tried something like this before?  Is there a better way to do this?  What could I do it wrong?  Any help is appreciated.  Peace, Matt

  

  Hi Matt,

  There are a few screws LabVIEW for coding/decoding Base64: http://decibel.ni.com/content/docs/DOC-5544

  I have not tried, but I expect that you can flatten to a string, convert the binary string to a string in Base64, and then define the string Base64 Descr property of the node DAQmx channel property. Data recovery would be the exact opposite.

  Yes, if the binding variable is declared as a clob, so it can store the maximum size of the CLOB, but this isn't your problem.
  Your problem is that you set the clob data using a string literal that is a single quoted string. There is a limit to the size of the string literals, so you will have to accumulate the clob in adding a whole lot string literals instead.
