For Loop with Error Check

Hello all,
As per my sample VI.
I gave Empty array to For Loop. As we know this Loop will not execute because N value “0”.
But, I want to know why Error out always giving True value. This Error Indicator value changing to “True” irrespective of Error In.

That''s exaclty what I said.
If you use plain tunnels and the loop iterates zero times, the output will give the default value for the datatype, which is FALSE for errors.
If you use shift registers, whatever is wired to the initializer terminal will be output unchanged on the right if the loop iterates zero times. Since you initialize with a error=TRUE, that's what you get.
This is all as expected. In your first post you claimed that the output is error=true using plain tunnels, which cannot be. Agreed?
If you want error=false with the shift register, change the diagram constant accordingly.

Windows Update failed to check for updates with error 0x800B0001

Hi all,
I have a WSUS installed on a Windows Server 2008 R2 box, I have a new Windows Server 2012 box (joined to domain) that cannot get updates from the WSUS, whenever I try to search for new updates I receive the following error in event viewer:
Windows Update failed to check for updates with error 0x800B0001
Note: I cannot see the Win2K12 server in the WSUS console under computers node.

I couldn't get it to run even after installing the mentioned KB fixes. So I investigated the error myself, and found a "hack" that seems to fix the issue. Wrote up a small piece on it here:
http://tplive.azurewebsites.net/2013/12/windows-update-error/
You and about a thousand other people have reported "I had already installed [the update], but installing it AGAIN fixed the problem.", which is almost assuredly a simple indication that the original installation of the update failed, and you simply did
not recognize that the installation of the update was not successful.
The fact that the /selfupdate folder was corrupted (read: missing files) pretty much says it all. There's no bug. Your installation of the update simply failed. (Or, the server wasn't healthy to begin with and you got what you got.)
Bottom line: The only known cause for a client-side 0x800B0001 error code is that the WSUS server has not been
properly and completely patched.

Swing : login with error checking

Hi all,
I am trying to write a login with error checking on the password. If password validation fail. It will remain there. If it passes it will go to the application. any samples and sites please.
thanks
andrew

CardLayout would be good for this sort of thing - allows you to lay panels on top of one another and then switch the display accordingly.
Thus, when your app starts up you show the login screen and then once a user successfully logs on you switch to the main application screen.
I put a basic example on another thread earlier:

Bug in conditional for loop with an empty array

There appears to be a bug in the for loop with a conditional terminal.
If an empty array is wired to an auto-indexed array input tunnel, an output array tunnel has one element instead of zero.
The array constant on the left is empty.
Top loop without the conditional terminal produces an empty array.
The bottom loop with a never true conditional terminal produces an array with one element

Creating the example from scratch, I do not see the error.
Neither do I.
If I add one or more elements to the array (constant or control), then delete them all (using 'Delete Element') the bottom array has one element.
Nup. Still empty.
If I empty the array (using 'Empty Array') both are empty.
Yep.
Also if I create an empty array using 'initialise array' with zero elements, I get one element.
Nup. Still empty.
'Show constant folding' does not appear to change the behaviour, but including a random operation in the loop does.
Agreed that constant folding doesn't cause any odd behaviour. Introducing a random operation (adding two constants) in the loop doesn't either.
I've tried all your methods here Trevor, but I can't replicate this behaviour in 8.5.1 under WinXP SP3. Sorry!
Maybe somebody else will be able to help, or find a useable workaround.

How to keep the field open for input with error message in report program

Hi,
Need a help in solving the below issue.
"How to keep the field open for input with error message in report program"
Regards,
C.Shasiraj.

Hi...
you have to use the event:
AT SELECTION-SCREEN ON <FIELD> EVENT.
u have to give an error message in this event.
Consider the following Example:
PARAMETERS : NUMBER TYPE I.
AT SELECTION-SCREEN ON NUMBER.
IF NUMBER = 10.
MESSAGE 'Number vakue is 10' TYPE 'E'.
ENDIF.
START-OF-SELECTION.
WRITE NUMBER.

in this if u give the value of number = 10, it will not proceed further, if u give some other value other than 10 you will proceed further...
Execute this program once u will understand....
also Consider the following links :

The demand of my application is that i can not replace for loop with a while loop.because i need fixed number of iterations and as far as i know fixed iterations could be only with possible with the for loop.

the demand of my application is that i can not replace for loop with a while loop.because i need fixed number of iterations and as far as i know fixed iterations could be only with possible with the for loop.
your recommended second option that i could add true/false case.
this true/false case must be inside the for loop or outside the for loop?if this case is inside the for
loop, how can i send stop command from outer while
loop?
more over do you have any example for this please?
thanks"

You can execute a fixed number of iterations using a while loop by comparing the iteration count to the number of iterations you want and wiring the output of that comparison (e.g. Less Than or Equal To) to the continue (or stop) terminal of your while loop. Which comparison you use depends on personal preference, where you wire the desired count and the interation count, and whether you're using the while loop as Continue if True or Stop if True.

For Loop with parameter in application process

Hello,
I am working on a project for school and a loop in an application process is giving me a headache. I have an application from which I make an ajax call to an "on-demand" process. Here's a short version of the process:
declare
valuesList varchar2(32000) := '';
sqlWhere varchar2(32000) := '';
begin
begin
//calculations, but let's hard code sqlWhere for demonstration purposes
sqlWhere := ' where ID = 50';
for j in (select * from myview sqlWhere) loop
valuesList :=valuesList || '~rowsep~' || j.id || '~colsep~' || j.beds;
end loop;
     exception
     when no_data_found then null;
     when others then HTP.p('Error: ' || SQLERRM);
valuesList := substr(valuesList, 9, length(valuesList));
end;
htp.prn(valuesList);
end;
I thought the for loop would contain only one record but it lists all records in the view. Interestingly, when I replace the loop condition to 'select * from myview where ID = 50' it returns what it's supposed to.
Could someone please explain what I am doing wrong?
Thank you!

There are a couple of different options but using a variable in the sql statement and not the where clause needs an execute immediate. The link below gives a good overview and options to accomplish what you are trying to do.

How to use for loops with Multiple Initializers and Incrementers

I found that my for loop is printing out wrong, because I am using two for loops. I have searched but all I can find out is you can't use multiple inializers and increments, does anyone know how to get around this? How would I use an array for this?
Thanks very much for your help.
import java.util.Random;
import java.util.Arrays;

int numnodes = 6;
//Randomly generate a number between 0 and 499 for the x and y coordinates for the nodes
Random randomGenerator = new Random();
for (int x = 0; x < numnodes; ++x) {
int randomInt = randomGenerator.nextInt(500);
Random randomGenerator2 = new Random();
for (int y = 0;y < numnodes; ++y) {
int randomInt2 = randomGenerator2.nextInt(500);
log("Generated : " + randomInt + " " + randomInt2);
log("Done.");
}

Sorry that code works, but I want to use both my x and y coordinates to get a random number from 0 to 499 in both of them, then I want to do some comparisons of the values, then return it to another function. As it stands now, I get the wrong results when I run it, as you can see at the bottom.
Thanks very much for your help. I have been stumped all mornign on this and have looked everywhere trying to find an example. I don't won't to use math random. I am on a tight deadline to finish and at the rate I am going, I will not complete it.

Mail for Exchange with error "Body Fetch Message T...

Hi,
I am just got the Nokia E71, and had installed the Mail for Exchange version 2.0.5(5), and had set all the required configuration (Exchange Server Name, UserName, Passowrd, Domain). But when I do the SYNC, it got the "System Error" from the log, and I check on the "admin_log1.txt", it show that "Body Fetch Message Too Large" error.
Any ideal on the error ? I have check the Access Point, there is working fine, as I can us the web browser on the phone, and no proxy setting
I also check all the Exchange configuration setting with using the Windows Mobile PDA phone to do the SYNC with our company Exchange server, it work fine with all the given configuration.
Please help.
Thank You very Much.

Is Mail for exchange working after the update? I am able to setup my company email, but mails are not getting downloaded. I tried entering a wrong password for my company email (after deleting my profile), just to check if mfe is able to connect properly with my company email server. It is able to identify that the email password i entered was incorrect. Also when I enter the correct password, setup finishes successfully. But its not retrieving any emails. I am sure of the settings, since the same settings were working earlier. Only thing i am doubtful about is the port number. Port number by default comes as 443. Does it need to change? Is MFE working for anyone? My company email is ************@hcl.com. Can you pls suggest?

"-error" "wStub" "721426". Printer is installed and working, but continuous install loop with error.

I get the above error, quotes and all, on my daughters computer recently. She is running Windows 7. The only change is that my husband recently did some network maintenence on her computer so that she could back up some of her media to the storage drive.
She was previously able to print from this printer (it's set up as a network printer, wireless for users) and had no issues. Now, she has this weird install loop. I was able to reinstall the printer despite the loop so that she could print again (it overwrote it with wrong data) but it still keeps trying to install and when the administrator permissions come up asking if we want to allow it, and we say no, then it cycles off and starts right back up again.
I have already followed the directions online for the re-regestering, and i have run a new virus scan.
What next?

Enhanced for loop with DirectoryStream in java 7

Hi, I'm a newbie to Java and am having trouble with the following code, which I'm trying to use to iterate through a directory and obtain the file names of all the pics to create thumbnails of them.
I've done hours and hours of searching on the web and find no answer for this one, so it's probably something very simple I've screwed up.
All assitance is appreciated.
The code segment:
 try (DirectoryStream<Path> ds =
 Files.newDirectoryStream(FileSystems.getDefault().getPath(dirNew)))
 System.out.println("at dirstream");
 System.out.format("toString: %s%n", ds.toString());
 for (Path p : ds)
 // Iterate over the paths in the directory and print filenames
 System.out.println(p.getFileName());
 System.out.println("at Path p : ds");
 thumbName = p.getFileName();
 createThumb(String.format("%s",thumbName));
 } catch (IOException e) {
 System.out.println("dirstream failed!!!");
// e.printStackTrace();
 System.out.println("atend of dirstream");and the output:
run:
/home/rich/Images/FromWeb-Misc/1
at dirstream
toString: sun.nio.fs.UnixSecureDirectoryStream@196b20e

Oracle recommended me to upgraded Oracle XML Parser for Java v9.0.4 (see note 271148.1), but it happends in only one instance.
In other instance, we haven't upgraded the XML Parser and We don't have the error.
Have you ever got this error or any similar error? What do you suggest?
