How do get an indicator to appear when using control references

Hi, can anyone help with the following?
I've just managed to resolve the problem of getting indicators of a sub VI to appear on the front panel of my main VI and remain active. This was done by using control references. Basically, I created a reference for the control on the front panel of the main VI. I then dragged the reference in the block diagram of the main VI to the front panel of the subVI to obtain a Control Refnum. Then in the block diagram of the subVI I created a property node and linked the indicator and control refnum to it. Then I wired the subVI's connector pane to the control refnums in the subVi front panel. Finally, I copied the subVI icon into the mainVI block diagram
and wired the references to the relevent renum terminals of the subVI connector pane. However, I'm still having a problem with one of the indicators, which I've called 'time limit reached?'. When the VI has reached the end of the run this indicator in the subVI changes from the word 'No' (surrounded by a red box) to 'Yes' (surrounded by a green box). In the sub VI this was done by using a comparison function and linking the visible property node to the 'time limit reached?' true/false boolean. I would like the same to happen on the front panel of my main VI. In this case where should I put my property node and control refnum? I'm unable to link a control refnum to the current visible property node. When I create a visible property node which can be joined to a control refnum then I don't have the option to link it to the true/false boolean. Any suggestions? I have written a small VI which demonstrates the problem if need be.
Thanks, Adrian

I would suggest to use a customized boolean instead of making it visible/invisible, just take a boolean, change boolean text from TRUE/FALSE to YES/NO and change also diferent cases colors, this way, you don't need to play with property nodes. If this can't be done for any reason, using a local / global variable is the only solution that comes to my mind.
Hope this helps

Main VI stops when using control references.

Hi, This is my first question on this forum. I've created an engine simulation VI which uses control references. The main VI has a data acquistion loop and control references. The control references link to another VI that runs an equation loop which continuously calculates engine speed base on data collected in the main VI. The control references work but the main VI data is collected and updated only once when the main VI starts. If I remove the control references from the main VI the daq loop runs fine. Thanks in advance for your help.
Mike

Joe,
Thanks for the response. I do not load the subvi dynamically. I have attached a similar vi to show what I'm trying to accomplish. The DAQ vi reads the input and calculates the power. The power is sent to the "engine momentum sub" vi where the speed, as a function of time, is generated and sent back to the DAQ vi. I created the sub vi to clean up and isolate the DAQ vi from the subvi. I wanted the sub vi to run at a certain speed (by adjusting the wait time)and not affect the DAQ vi. If you input a value of 10 into the DAQ vi and then start it you will see the speed ramp up to 100. While the DAQ vi is running, I need to be able to change the input which would cause the power to change and in turn change the speed. I thought the control r
eferences were the way to go. In my real DAQ vi, I have many more inputs, all which do not update after the first reading. I considered putting the DAQ functions in another subvi and reading the outputs through control references but that seemed too cumbersome.
Thanks again,
Mike

How to get the PDF Document version when using Digital Signature

Please suggest me the how to get the version data from the form.

Hi Mithun:
I think I have run into a similar issue and have not been able to find a resolution.
I have been trying to place three groupings of data and limit them to 15 rows; additional rows would print on a void check on a next page using the rtf template.
Earnings .............. Pre-Tax Deductions .........Taxes
<line 1 earnings> <line 1 pre-tax deductions> <line 1 tax dedcutions>
<line 2 earnings> <line 2 pre-tax deductions> <line 2 tax dedcutions>
<line 3 earnings> <line 3 pre-tax deductions>
<line 4 earnings> <line 4 pre-tax deductions>
<line 5 earnings>
<line 6 earnings>
The template works fine with these lists as nested tables until I add in the restriction and filler for the 15 rows for the first table. The data in the 2nd two lists does not appear once the limitation is added.
Check Writer (XML) - Issues with payroll check stub in rtf
As an alternative, I have been thinking adding the remaining line totals (over 15 rows) and adding a 16th row. However I have been running into an error when trying to use the code for-each-group.
*** XML-22056: exactly one of four group attributes must be present in xsl:for-each-group
Can you send me your template to review? My email is: Karen.Lacey(AT)paetec(DOT)com
Thanks!

How to get the total page number when using Crystal Report in JSP

In my JSP, I use the class CrystalReportViewer to generate and display the report views. But this class only sypply the function to get the info of the active view.
Thus with this info, I only can get the active view's page number. How can I get the report total page number without showing the last page first?
Thanks.

Anything you do without submitting to form has to be done on the client side (ususally by JavaScript) using data which has been send already from the server.
With JavaScript you can do quite a bit. You can download tables which don't necessarilly appear on the screen, loading them into JavaScript arrays by dynamically generating javascript. Then you can pick up events like drop-box selection and use these tables to chose what you do next (e.g. preloading other fields, setting drop box content etc.).
Or, you can cause forms to be submitted when actions like a selection happen without the user clicking a button. It's generally a matter of how much data you'd need to transmit.
Another posibility is to use a Java applet, which can generate requests to the server and handle the results as it chooses. That are a number of problems with that but occasionally it's the best solution.
What you can't do is to handle user input inside a JSP. The JSP has come and gone before the user even gets to see your form.

How to get more detailed error messages when using Oracle JDBC

Here are some typical Oracle error messages that leave you guessing :
"ORA-01722: invalid number"
"ORA-00904: invalid column name"
Is there any way to find out which number or which column name is invalid ?
Why doesn't Oracle include this information in the error messages ? If it knows the number or column is invalid, it must know the number or column name !

Launch the query under sqlplus, it'll tell u :
SQL> select user_id, userna from dba_users ;
select user_id, userna from dba_users
ERROR at line 1:
ORA-00904: invalid column name

First click on the Apple > Logout and Log back in or restart the unit see if that solves it. If it doesn't do you have a backup of your system prior to upgrade? Check Disk Utility and see how much space is being used to make sure the drive wasn't somehow erased.

I am able to get the 'Home sharing' 'user and password on my Mac.
Also using IPad 2 I am able to get the ITunes to accept the user name and same password as the Mac.
However, the only way I can see the 'Home sharing; icon is in Music on the Ipad. When I tap on the Icon it asks for a password.
When I give the same password, it is rejected.
Help!!!!

Personally I think the iOS devices are poor at reconnecting - Airplay establishes that a link is available but when the iPhone/iPad has been away from the house and rejoins the network i think AppleTV already thinks it's connected with a different IP address and fails to recognise it has joined the network again with new credentials.
Something along those lines anyway.
I find that a combination of restarting AppleTV, router and iOS device tends to fix it, but not for everyone.

These issues are causing me to use Chrome very often even though I like Fox better. I've searched and searched how to get help and cannot find anything. How does one get personal technical help?? These issues do not happen in Chrome at all. Thanks.

How to get the full image directory when i upload the image to web page???

hai, how to get the full image directory when i upload the image to web page???
here is the example:
<form action="uploadfile.jsp" method="post">
image<input type="file" name="image" />
<input type="submit" value="submit"/>
<%
String s=request.getParameter("image");
%>
<%=s%>
</form>
i upload the image from C:\image\center.gif. i use request.getParameter just can get the image name like "center.gif". Can anybody help me how to get the full path name. Thanks a lot..

There is no need to get the path. It is also fairly pointless as the server cannot access the client's local file system.
Carefully read this article how you can upload files the right way: http://balusc.blogspot.com/2007/11/multipartfilter.html

Hello Leonie!
I use Iphoto sharing with my family on their ios devises. And it works.
The only problem is that, now, I try to organize the photos in a meaningful way (not chronologically) before Iphoto Sharing (Icloud)
But on the ios devices the photos is arranged chronologically.
Is there a solution?
