  The joint vi (LabVIEW 2012) will return the value in cell "A1" "Sheet1" of the already opened excel workbook "Book1".

  Change the values for your specific names in the workbook and worksheet and of cells needed.

  The value returned is a Variant needs to be converted with 'Variant to data' according to the type of data

• Read excel cells into variables

  I'm trying to read cells of an excel file and store the contents in variables. The idea is to pass information such as the numbers test, high/low limits, ect.

  I looked through the activex/excel samples and found excel2000dem which has a function called ReadDataFromExcel. I copied over the

  Excel2000.h file, most other variables and defines that it seemed to need. I get no error to generate/compile but when I SHIFT/F5, I have 7 errors of link

  for symbols not defined such as ' _ExcelSheetsItem @28' and '_ExcelWorkbooksOpen@208'. '.   I am new to LabWindows so I don't know how

  track down a link error. Can someone point me in the right direction?

  Well, I think that I finally managed to pinpoint the problem. It seems that the file .c for this instrument has been disconnected. Here's how to fix it. Go to tools and select Edit. Then click Attach and Edit source. Recompile it and I hope that set the excel2000.c on the instrument. Go ahead and try this.

  Hello to all,

  The problem of the modes of compatibilities between 2003 and 2007-2010.

• Link an Excel cell in a block of text in InDesign

  I hope to incorporate an Excel cell in a text box and have this value in the text box the file exchange linked Excel is updated. Imagine the following: "... There is a significant number of 123456 and the text goes here...". »

  
  So far, I could successfully change the preferences so that a linked Excel file is linked and can be updated, but it's an entire file, or range of cells in its own table.

  I have JUST the text in the cell appear (with no discernible denotation of its attributes) in the static text block and be linked to an update in the links Panel?

  Why is BTW that sometimes only the first two columns appear in the table?

  Thank you all

  
  

  This is the solution!

  A table online!  I made a small framed, linked to the cell, then makes an inline element in the paragraph of the text. Then it's just hair she and design.

  Thank you very much

• The referenceing cell value against a form to anoter forms

  I have two forms of data. Form A and B. I'm writing the formula (columns added formulas) member in form B.
  I need to get A formula cell values. How reference to the cell in B forms.
  Such as in excellent we have 2 sheets and we can reference the a cell in another worksheet values. I'm doing it in the form of Hyperion.
  Please suggest me how I can do
  Thank you

  If she is separated, forms, then it will not work as the formulas are run on the active form, I thought that it would be possible with composite forms, but as I said, I didn't have much success.
  The other way, as suggested to have formulas in a member and access the Member between the forms.

  See you soon

• OnDrawingCell seems to be to delete all cell values

  I paint a capable 2D on a report that I did successfully with the result I want. It may be important to note that all cell values are expressions, not channels. It looks like this:

  

  My final step is to change the background color based on the value of the cell.

  Following the example "to help for orders for trend displayed in user Tables", I saved a script separate with the new command and put in place a column to use. On the test of the script, all THE contents of header cell has not disappeared from the table! Now, it looks like this:

  

  The new user control is in the HealthCellBackground.vbs file as follows. Note that currently all the contents of the command is commented on, which would theoretically result in any changes to the table and theoretically could not be hidden in bugs.

  void TabHealthOnDrawingCell (context, cell)
  
    Dim dCurrVal
  
  '  dCurrVal = val (Cell.Value)
  
  '  <= 9="">
  
  '    If dCurrVal > = 100 then
  
  '      Cell.BackgroundColor.SetRGBColor (RGB (50, 150, 50))
  
  '    ElseIf dCurrVal > = 25 then
  
  '      Cell.BackgroundColor.SetRGBColor (RGB (175, 230, 200))
  
  '    Else
  
  '      Cell.BackgroundColor.SetRGBColor (RGB (255, 50, 50))
  
  '    End If
  
  '  End If
  EndSub ' TabHealthOnDrawingCell

  The command is saved as:

  ' Saves a user REPORT function,.
  
  ScriptCmdAdd("D:\LabVIEW\Project\DIAdem\HealthCellBackground.VBS")

  The content of the script for this column is:

  Set o2DTableColumnExpression = o2DTable.Columns.Item (2)
  
  Set oColBG = o2DTableColumnExpression.Settings.BackgroundColor
  
  oColBG.ColorIndex = eColorIndexFillEffects
  
  oColBG.RGBFilling = RGB (147,225,225)
  
  oColBG.RGB = vbGreen
  
  oColBG.GradientDirection = eColorGradientHorizontal
  
  oColBG.GradientMode = eColorGradientModeFromInside
  
  o2DTableColumnExpression.settings.OnDrawingCell = "TabHealthOnDrawingCell"

  Commenting simply on the last line of the final snippet above will restore the cell values. The above images were generated by enabling / disabling just that character of a comment.

  Just for mental health, I tried to use the command in the example, TabTrendOnDrawingCell_Case1, and he gave the same results. Based on the evidence so far, something goes wrong with the record, either it is the contents of the cell as expressions that cause the problem.

  Any ideas?

  Hi gizmogal,

  I have reproduced a table with the expression of group name in your message and also had problems until I changed the scale of the entire table to have the right fixed number of lines.  If all you have are expressions, there unfortunately no way around to a static number in the number of rows in the table.  The expression Root.ChannelGroups.Count works to the right of the expression in the configuration dialog box you posted, but it does not work in the global table scaling tab, and that has to be right.  By default, DIAdem paintings list of 10 lines - my guess is that you had less than 10 groups in the data portal when you got this error.

  All 3 of your table configurations are expressions, if you need to list them as expressions, not variables.  A variable would be the name of a global variable that contains the information you want to display.  Unless you have created the global variable and filled with the value you want to display, you cannot use a configuration of variable type.

• read the independent values in a channel

  Hello

  I want to read the value of a chanel.

  I guess that every chanel's store as an array with an index and a value.

  I would like to read a value of a chanel with its index number, then do some calculations, and then write to it.

  For example:

  Chanel 1:
  index value
  1           1
  2           1
  3           1
  4           2
  5           1
  6           1

  start index = 0
  value > 1?
  If no control of the following
  If so do something

  Do you have a sample script to read a unique value in a chanel?

  Kind regards

  Frédéric MANUAL

  OK, so it should work

  Dim oChn, K, value
  "Go to the channel you are interested in.
  Set oChn = data. GetChannel ("Time")

  ' loop through all the values
  For K = 1 To oChn.Size
  Value = oChn (K)
  If (value > 1) then
  "do something
  MsgBox ("value WG 1")
  End If
  Next

• Read the output values after each step runs in the User Interface of LabVIEW

  Hi all

  Development environment: TestStand 2010 SP1 and LabVIEW 2010 SP1

  Problem: is there a way to run the following steps programmatically and get values out of each of them?

  I have already extended a bit a complete interface IO for TestStand load any sequence, choose among the measures and execute step by step (something as an alternative to the steps run selected). What I'm trying to do is to add some actions between each step and do in the UI (I can't change the sequence!), so I start the NewExecution with some previously configured InteractiveArgsParam and option breakAtFirstStep set to true. Eventually I do just something like step over when debugging the sequence and it works well, but I didn't do well a way yet to read the output values of the place...

  So, if I wait before the end of the run I can read my results by treating the ResultObject, but it works only after the completion of the test sequence. Because I wanted to stop after each step, read the values, do some actions and continue to the next step, I've tried to register a running Trace event reminder View Manager. I see that after each step is executed, this event is fired, but when I try to read that a ResultObject returned in the event data it is not filled with values (ResultList seems to be empty?). Is this a correct behavior or maybe I'm reading the wrong way? (It's the same VI regarding the reading of the ResultObjects after the sequence ends and there it works very well for tables, containers and other types of data).

  As I mentioned I can't change Test sequences, I can not add a UImessages.

  What are my options? If the trace event returns output all the values from each steps or is it just used to check the status? Or maybe there's a completely different approach to this issue?

  Thanks in advance for your suggestions,

  Best regards.

  When you manipulate the UIMessage trace (you need this before the return of the event or you will present the race conditions), download myuimessage. Thread. Then call Thread.GetSequenceContext (0, & Iplease).

  And then on the context of the sequence, either go to PreviousStep.Result if it exists, or watch Locals.ResultList.

  Trace events occur between the steps executed step the more recently is the previous step, but it is also a trace event to the beginning before any measure have run at this time, there will be a previous step.

  Hope this helps,

  -Doug

• Read the last value of a large file of PDM

  Hello everyone!

  I hope someone can help out me with this one.

  I try to put in place a program that can read the last value of one of the large channels of different TDMS files but I just can´t find a way to do it.

  I would appreciate help for my little problem.

  Thank you very much in advance for your support.

  Kasim.

  Hello

  You can use the following playback TDMS Set Position feature included in the PDM API.  This function receives a parameter called "(0:start)", which can be set to 1 to go to end of the file.  In this way, you can read the last value written to the PDM file.

  I hope this helps!

• MAX is reading my PLC values as decimal type, but they are BCD

  I have a Koyo sold by Automation direct plc.  All values of the automaton are BCD, but in the measurement and Automation Explorer, they are read as decimal values.  Does anyone know how to convert, OPC server is on the MAX so that I can read my values, because they are?  The database of the Citadel is useless for me without eigenvalues.  Belvedere offers the possibility of advertising ": b ' to your tags to read as BCD.  LabVIEW tools and it offers a similar way?

  Your opc server program should have a specific format for reading the data of the BCD. Here is some info for kepware.
