Table indicator formatting strangeness
I'm hoping someone here can shed a little light on this one for me.
I just started working on a project involving a MySQL database. I'm new to MySQL, so I may be looking in the wrong place to solve this error.
For some reason my table in LabVIEW is appending today's date to my StartTime and EndTime columns. But when I use the MySQL Query Browser or the command line interface, I do not see the date appended to those columns.
The time format is also different in my LabVIEW table. The time data was entered into the database in 24 hour format. If I view that data through either the Query Browser or the command line, I see it in 24 hour format. But my LabVIEW table shows the time in 8:00:00 AM format.
Is there anything I can do to eliminate this behavior?
I've tried looking for something in the Properties, along with what is available through property nodes. So far I haven't found anything.
The time formating I could probably live with. But I definitely don't want dates appended to my time columns.
I've included a couple of screenshots to illustrate what is happening.

I'm using some of the VIs from the Database Connectivity Toolkit. In this case, it would be the DB Tools Select All Data.vi
I'm including my code here as well.
One thing I just noticed was that my "Select All" VI I'm using isn't in the DCT pallet. I'm not sure where it came from actually. Probably from an online example or something.
I tried using the DB Tools Select Data.vi from the pallet. But the data output from that VI is a Variant.
For some reason, the Database Variant to Data.vi on the pallet couldn't/wouldn't convert the variant data to the 2D array of strings that I'm using in my table. It kept calling my sink type as "void". I had to use the Variant to Data.vi from the Variant pallet.
This introduced a huge performance problem though. The table I'm accessing has about 19000 rows in it. My first VI pulled all this data out in just a couple of seconds. The second one where I had to convert the data took so long that I thought the application had hung. It would be unusable. When it does finally spit out the data, it's in the exact same format as the first VI. Maybe I'm doing something wrong with the way I'm converting it?
I'm including the second VI as well. Hopefully I can get to the bottom of this.

How do I change the background color of a row in a table indicator?
Hello,
How do I change the background color of a row in a table indicator? I know how to change the background color in a active cell, but that is not what I want. My first intent is to make the background color of the first row a unique color, such as green, just to highlight the top row of the table.
Regards,
Kaspar
Regards,
KasparI have done this before by using a for loop to change the active cell of a row in order to give the appearance that the whole row is turning the color at once.

Source agent: FM 9.0p250, unstructured
Transformative agent: RH 8.0.2.208
OS: WinXP Pro V. 2002 SP3

Is anyone else experiencing problems with RH not correctly transforming FM figure and table titles? I can get most of my design to work, but I am having a problem with RH not following-through with some of my table title format and figure title format specifications.
I am having problems with RH not correctly applying, or inconsistently applying, figure title and table caption attributes ("Paragraph" settings) that I specify through Project Settings | Import | Edit | Conversion Settings.
For example (in FM Table Designer), I have a table title paragraph design, "TT.Table Title", in which I specify Title > Above Table, and specify a paragraph design (FM style) of Arial, 10pt, regular, bold, 0" indents, alignment left. It works fine direct to print or PDF; the same is true with figure titles.
In RH (through Project Settings | Import > Edit | Conversion Settings [FrameMaker Settings] > Paragraph), I specify that the FM style is to transform through an RH style that I define (through Edit Style button > Styles > Format > Paragraph). I set the alignment, etc., as is required through RH, but when I look at the Design view and/or generate the output (say...Webhelp), RH has not correctly interpreted one or more of my specification's attributes.
For example, in the case of my table titles, in Design view, RH has centered the title (or in RH terms, the ''Caption") above the table. Or sometimes the bold attribute is missing. In Project Manager, if I right-click and select View, the title/caption sometimes appears as specified; however, if I Generate the WebHelp (or HTML Help, or whatever), the bold formatting isn't there.
I thought that maybe RH defaulted figure and table titles to a Caption, as that is what it calls that part in the Design view. But when I set Caption to my specs, it made no difference.
Any thoughts?
Thanks in advance!I may be off at a tangent here as this is a wild guess.
HTML recognises Table Heading and Table Text, RH does not recognise the Table Heading selector. Maybe with your knowledge of FM's table caption and that tidbit of information, you can change something in your FM table to avoid the problem, if indeed there is a link.

Is it possible to wrap text in cells of a Table indicator?
I have read the contents of an Excel file into a Table indicator and would like to wrap text within certain cells.
Solved!
Go to Solution.You can do this - sort of...
LV will not auto wrap the contents of a cell automatically. However, if there are hard line breaks, you can make LV expand the cell vertically to show all the lines. It will not however, autoutomatically size the cell width.
Sounds like this might be a good project for an XControl.

Why does a digital indicator formatted for time & date add 16 hours to the input?
I wire a digital indicator with a double precision value that is supposed to indicate an elapsed time. But the indicator (formatted for time and date, with the date inactive) always adds 16 hours to the wired input.
This problem occurs even in a simple vi I wrote that only consists only of a constant wired to the indicator.
Using LabView 6.0.2Labview interprets the number passed into an indicator formatted for date & time as seconds since Jan. 1st 1904. I'm assuming that since you're looking for elapsed time this is not what you're passing in. One thing that I've done is get the elapsed time in seconds and write a routine to convert that into whatever format you want.

Calculated Percentage Columns in Pivot Table loose formating in Excel
I have a simple report built using pivot table ( OBIEE 11.1.1.5.0)
1 Metric and 1 dimension using pivot table. and I duplicated the metric column and change it to % column.(Show data as % of column). SO far so good. Below is the snapshot
http://tinypic.com/r/2s14xa9/7
Now i download the report in excel and all the % values are messed up . Below is how it looks
http://tinypic.com/r/bede90/7
I tried messing with data formats etc..nothing works.. I cannot add a custom column format to the metric column since it will impact the derived % column.
Is this a bug ?Any pointers ..
ThanksHi,
Follow up this SR:
SR 3-5060435331: Calculated Percentage Columns in Pivot Table loose formating in Excel
Workaround: (not sure may be give a try)
also give a try like below one then try to download it may work.
In that % column -->add the below statement in the Custom CSS section of the column properties:
mso-number-format:"\@"
Refer snapshot here:
http://i53.tinypic.com/a09kqv.jpg
This will treat the data in the column as text while downloading to excel, hence retaining any leading or trailing spaces.
Thanks

Can you stop table indicator cell editing?
Hello,
Is there a way to disable the ability of a user to edit the cells of a table indicator? I have a table indicator on my front panel and just want it to be a indicator, nothing else. I have found that I can change the contents of a cell in the table indicator and type in any value I want.
Regards,
KasparA technique I have used at times to quickly disable multiple controls at one time (provided they are located near each other) is to create a simple string indicator that is transparent. Size it so that it covers the controls (in your case the table) that you want to disable. In your code when you want to disable those controls use the property node to make the transparent string control visible. When you want to enable the controls use the property node to set the "visible" attribute to false. This is a simple trick that can be useful at times.

Analyzer - Table header formatting
Hi @ll,
I`ve formatted a BEx Analyzer workbook to our requirements. The only thing I can`t change is the table header.. Could anybody tell me how to change the table header formatting?
Regards,
FloHi,
Open your workbook. Go to design mode, select the design item in the header and delete the design item.
Again click on design mode to come back to original workbook and click on header and delete the header bar and give the table header as per your requirement.
To format the table header, right click on header and use excel foramatting(Font size, font & font style).
Hope it is helpful.

Hi All,
Am using OPENROWSET to load the file data into table, here the problem is i need to map same input value to two different columns of table, As format file doesn't allow the duplicate numbers am unable to insert same value to two columns, please help me to
find a solution for this.
i can use only OPENROWSET because i need to insert some default values also which come based on file. only the problem is how to map same input value to two different columns of table. please give me the suggestions.
Thanks,
SudhakarFrom what you say:
INSERT tbl(col1, col2)
SELECT col1, col1
FROM OPENROWSET(....)
But I guess it is more difficult. You need to give more details. What sort of data source do you have? What does your query look like? The target table?
Erland Sommarskog, SQL Server MVP, [email protected]
Hi Erland,
Thanks for your response
my source file is text file with | symbol separate for ex:
1002|eTab |V101|eTablet|V100|Logic|LT-7|Laptops|SCM
Database table have columns like
column1,column2,column3...etc, now i need to insert same value from input file into two columns for ex:
the eTab value from text file has to be insert into column2 and column3 of
table
we cannot change format file like below one
for the above situation how can we insert eTab into column2 and column3
Thanks,
Sudhakar. -
RH 9.01 Table Captions Format Problem
I created WebHelp in RH 8 / TCS 2.5. The table captions are fine, Arial, Blue, Italic
I made a few minor updates to the table contents (not the caption) in FM 10 / TCS 3.0.
I open the project in RH9 / TCS 3.0 and regenerate.
The table caption is Times Roman black.
I cannot modify the table caption format to be anything else besides Times Roman black.
The RH files show the correct format.
Here's what I tried:
I tried manually inserting a table and formatting the caption.
I tried creating a CHM file instead of a WebHelp file. Same problem.
I tried with two different projects. Same problem.
I did not try creating a new project.
Am I missing something, or is this a bug?
Thanks for any clues.
I tried attaching screenshots here, but I must have some IE setting disabled because nothing happens when I click the camera.Welcome to our community
I'll begin by saying openly that I'm a big ole Frame ignoramous. I'm a RoboHelp guy.
I find that in order to specifically style my table captions I first need to edit the CSS file using Windows notepad. Pop the following code somewhere in the file:
Once you do this your Styles dialog will have a caption entry in the Other category that you may format.
Seems to work on my own setup. Hopefully it will work for you.
Cheers... Rick

Table date format - How can I display Week 1, Week 2, instead of the date?
I would like to creat a table for my Gantt, that displays the week number unit, as I have as the middle tier in my timescale on the Gantt side of the view. I cannot find how to do this anywhere. I know I can change the way the date is displayed,
format wise, while in the table edit area, however one of the choices is NOT the week #. The data must exsist as the timescale displays it!
My goal is to creat a table that instead of showing the start date for a task, displaces the start week: i.e. Week 1, Week 2, ...ect.
Any help is appreciated,
Craig.Craig --
Bad news, my friend. What you want to do with the date format in the table cannot be done. The format you see in the Timescale bar is simply not an available date option in any table. Sorry.

Hi,
I am displaying a list of filesfrom a directory in a table on the front panel of a VI as part of a program I am developing. I would like the user to be able to select from that table so that particular file can be processed. Is there a way to do this?
Thanks,
Aaronyou'll find that most of the useful functionality of the labview user control interface is hidden within the property node and invoke node functions. just right click a control or indicator terminal on the block diagram and mouse over to create, then to property node or invoke node. lots of fun stuff in there. attached is an example. one file is saved for labview 8.0, the other is saved for labview 8.6.
