Writting to an specific spreadsheet of an existing excel file.

I need to write a labview 2-D array of real numbers to an specifc spreadsheet of an existing excel file (which has many sheets and is located in my hard disk).
Some years ago a member forum wrote a nice and small code for writting to excel. The code is http://forums.ni.com/ni/attachments/ni/6170/107/1/Excel.vi and was posted here http://forums.ni.com/ni/board/message?board.id=6170&thread.id=105
I found that it would be useful after some modifications. How to modify it in order to get what I need? (Obs.: My LabVIEW version is 8.0)

There is a function to do that in the Excel specific VIs palette of the Report Generation Toolkit. Of course you need to have the toolkit installed. You can also use the invoke and property nodes on the Excel object but you have to find out what are the appropriate methods to use and propriety to set (you should find the information in an Excel programming manual. in VBA it is something like worksheet("Sheet2").Select). You can use the Workbook OPEN method to open the Excel workbook saved on you hard disk (connect your file path to the Filename input of the invoke node).

Auto delete everything but specified folder contents from txt file

Hey Guys,
I am brand new to using Powershell (like 48 hours into using it for work) and I've run into a bit of an issue. I've only taken a programming concept classes so some of the stuff makes sense to me but a lot of it is new. Basically I've made a
script that automatically deletes any files over X amount of days. My next step is to have an exceptions text that will have a list of folders that should not have its contents deleted. This is what I have so far.
$Date= Get-Date
$Days = "7"
$Folder = "C:\publicftp\users"
$LastWrite = $Now.AddDays(-$Days)
#----- getting DO NOT DELETE listing from TXT ----#
$Exceptions = Get-Content "c:\exclude.txt"
$Files = Get-Childitem $Folder -Recurse -Exclude "c:\exclude.txt" | Where {$_.LastWriteTime -le "$LastWrite"}
foreach ($File in $Files)
if ($File -ne $NULL)
Remove-Item $File.FullName -Exclude $Exceptions | out-null
I've seen a lot of threads that show how to auto delete contents or how to exclude specific file types but I haven't seen an answer to my particular problem. Any help would be greatly appreciated! Thanks!

Hi Rabbot,
The script below may be also helpful for you, and uses the -whatif parameter in Remove-Item cmdlet, which doesn’t actually remove anything but simply tells you what would happen if you did call Remove-Item.
$Exceptions = @()
Get-Content "c:\exclude.txt" | foreach{
$Exceptions += $_} #store the exception file to array
$Folder = "C:\publicftp\users"
$LastWrite = (get-date).adddays(-7) #over 7 days.
$Files = Get-Childitem $Folder -Recurse | Where {$_.LastWriteTime -le $LastWrite} #filter files which over 7 days.
Foreach ($file in $files){
if ($Exceptions -notcontains $file.fullname){ #if the file is not listed in the exception array.
Remove-Item $File.FullName -whatif} #use -whatif to test
I hope this helps.

A better way to search a string in a 3GB txt file

I am looking for a string(12 characters) in a 3GB txt file. I use the file reader to go though each line and use the startwith() (that 12 characters are from the beginning of each line) to check if that line contain the string I am searching for. Is there a faster way to do it? Thank's.

I would avoid using java to parse/search a 3 GB text file at all costs. Any java solution is going to have terrible performance and you may run into memory problems. I would recomend that you either a) develop a native method for resolving this search and just invoke it from your current java class or b) use Runtime.exec to invoke a native OS command for searching the file (like grep or find) and parse the results. ....
I'm not even sure how I would complete that task with java exclusivly ... maybe break the file into smaller parts, then iterate through each smaller, temporary file ... I would really recomend storing your data in a different format if possible. A 3 GB text file just isn't very partical or secure.
... oh, to answer your original question (which I'm not sure if I all ready did), the fatest way to load the file is to wrap it into some BufferedReader. The fatest way to perform String searches is through the java.util.regex package if you have access to the 1.4 API. Other wise, just use basic String searches, as you all ready are.

Format number to specific string form

Dear fellow Labview users,
I'm quite familiar with Labview but for some reason I cannot figure out how to do the following:
I need to format a number (any number given) into a string of the form 'mmmmee' where m is a digit and 'ee' the exponential. For example:
0.0128 becomes 1280-5
1654086 becomes 165403
0.0000006 becomes 0600-9
etc.
I would appreciate any advice.
Thank you!
Solved!
Go to Solution.

Here's a quick draft. I am sure some of the regex wizards will come up with something simpler.
It sitll needs some work. For example if the value is zero or negative, or if the resulting exponent is more than 2 digits, you also need extra handling. I currently deal with negative exponents that are more than 1 digit (i.e. 2 digits, including the sign).

Acrobat 9 Pro: Batch Export Form Data to TXT?

Is it possible to use Acrobat 9.0 Pro's batch processing utility (Advanced > Document Processing > Batch Processing...) to export a bunch of PDF forms to individual .txt files (Forms > Manage Form Data > Export Data...)?
I can't find access to the Forms menu in the built in Batch utility wihen I click "New Sequence...", so I imagine it might take some custom JavaScript, which I'm not super experienced with, but I muddle through reading JavaScript code and understand it.
So, if someone can give any direction, I'd appreciate it! Thanks!

I'll try and read through the API Reference, but can't I just use a relative file path... something like this.exportAsText(true, null, "\..");
I don't know the correct syntax for filepaths in JS... does it get wrapped in double quotes?
The JavaScript for Acrobat API Reference says:
Paths
Several methods take device-independent paths as arguments. See the PDF Reference, version 1.7, for details about the device-independent path format.
Where the hell is the PDF Reference, version 1.7???
Is there a this.filename property?

Replace specific string in a file while reading it

Hi,
I am kind of an in between learner & intermediate programmer. I am trying to replace a specific string pattern in a file by reading it using BufferedReader & BufferedWriter. I tried it for 2 days. Can anyone give me a piece of code which reads a file line by line and replaces the specific string format with other? I tried replaceAll(regex,replacement). Nothing is working.

}when I wrote it, I was sober and bored
now I'm drunk and amused
god
did you try and remove the magic "static" keyword ?
I wrote it static because I didn't refer to any class
member when I wrote it and that's what I felt
compelled to do, though I feel nowadays writing
anyting static suggests some design mistake

Hi Pravin Baji
Try this code to load your form
Private Shared UIDPath As String = "Application/forms/action/form/@uid"
Private xmlDoc As XmlDocument
        Protected Sub LoadXml(ByVal xmlFile As String)
            xmlDoc = New XmlDocument()
            If Not System.IO.File.Exists(xmlFile) Then
                xmlFile = xmlFile.Insert(0, "..\")
            End If
            If System.IO.File.Exists(xmlFile) Then
                xmlDoc.Load(xmlFile)
                formUID = xmlDoc.SelectSingleNode(UIDPath).Value
            Else
                oApplication.MessageBox("ERROR: File " + xmlFile + " not found", -1, "", "", "")
            End If
        End Sub
Protected Sub LoadForm()
            If xmlDoc.HasChildNodes Then
                xmlDoc.SelectSingleNode(UIDPath).Value = formUID + System.Math.Max(System.Threading.Interlocked.Increment(counter), counter - 1)
                Dim xmlStr As String = xmlDoc.DocumentElement.OuterXml
                oApplication.LoadBatchActions(xmlStr)
                Dim oForm As Form = oApplication.Forms.ActiveForm
                Try
                    Dim oUDS As UserDataSource = oForm.DataSources.UserDataSources.Item("FolderDS")
                    If oUDS IsNot Nothing Then
                        oUDS.Value = "1"
                    End If
                Catch generatedExceptionName As Exception
                End Try
            Else
                oApplication.MessageBox("ERROR: XML File containing the form not found", -1, "", "", "")
            End If
        End Sub
Hope this will solve your problem

Writing to specific cells of existing Excel file and saving as a new file using LV 8.6

Hi all,
I am new to LV and am currently tasked to create a program that can open an existing excel file, input data in the program that will be written to a specific cell in the excel file and then saving the current edited file as a new file.
I have browsed through all the forums but I am unable to view the examples sent in them as I am using LV 8.6 which is why I am still having trouble visualizing how to create a program like this. Can anyone help me and mentor me how to write this program in this version of LV? I do not have a microsoft office toolkit hence another approach could be preferred. Thank you.
Aaron
Solved!
Go to Solution.

Thank you for helping me on this. However I do not really understand how does ActiveEx work. I have created a Vi according to the picture that you provided but there was some error in running the file.
Below is my own VI that I am trying to create. It consists of multiple string inputs which I am trying to input each into an existing file. I have created a separate txt file which has the cell numbers. I am trying to allocate each string into each respective cell in an existing file. I am currently having the problem of doing this "allocation" of each string as I do not have the microsoft office tool kit. Is there any other way for me to do so?
Also, I would like to save the newly created file as a new file with the name as seen in my VI. How would I be able to do it?
Please help me as I am stuck here but do not know how to continue

Disabling Deletion of Specification

Hi!
We are trying to grey out the option to delete specifications thru security roles but we couldn´t figure out what needs to be updated to prevent users from deleting specs (nothing showed up in the trace). We were wondering if this may be related to configuration.
Is there something in configuration that can restrict that functionality? Is there something that can be set up thru security to disable this option?
Thank you,
Eugenia

Hello Eugenia
specifications are used in EH&S to do a lot of things. At least if:
a.) a released report exists per specification
b.) the specification is used in a composition
etc.
you can technically not delete the specification any more. Furtheron it makes no sense to delete a specification if you have e.g. assigned materials etc. and if i remember correct it is not allowed any more to delte such a specification.
Furtheron you can not manipulate by standard the spec type after generation of the specification (e.g. try to convert a REAL_SUB to a LIST_SUB) etc.
As Keerthi explained: there is no separate activity type to assist.
With best regards
C.B.

Check access object like: C_SHES_* You will find easily all objects which are delivered by standard and used by standard in EHS.

How to delete string or line from unix file(dataset) of application server

Hi Rio,
I faced similar kind of issue working with files on UNIX platform.
The line is a line feed to remove it use
DATA : lv_carr_linefd TYPE abap_cr_lf VALUE cl_abap_char_utilities=>cr_lf.
DATA : lv_carr_return TYPE char1,
         lv_line_feed   TYPE char1.
lv_line_feed   = lv_carr_linefd(1).
lv_carr_return = lv_carr_linefd+1(1).
Note: IMP: The character in ' ' is not space but is a special
character set by pressing ALT and +255 simultaneosly
REPLACE ALL OCCURRENCES OF lv_line_feed IN l_string WITH ' '.
REPLACE ALL OCCURRENCES OF lv_carr_return IN l_string WITH ' '.

Delete record from the form and from the database

hi,
i want delete record from the form and the database ,but the record is only delete from the from !!!
this is my code :
if //condition then
delete_record;
commit;
end if ;
Any solutions ??
thnx

You have unique key field(s) on the table you are trying to insert which actually restricts you from inserting the same value again.
When you are deleting the record and issue commit there is a record to be inserted in the table which is a duplicate that's why you are getting this unique error.
As oracle is not able to insert your commit fails and stops your deletion of record from table

Urgent: deleting a specific string form an existing .txt file
