Bug with Base LVOOP object variants and flatten string.

I found a bug when if the base LabVIEW Object is wrapped in a variant (even indirectly), it cannot sucessfully be flattened to and from a string.
Neither of these should produce an error.
And if you try to work around it with XML, it can lockup or crash.

The first is the simplest demonstration of the problem.
The second is to show that problem is indirect (through multiply layers of different structures).
As for the purpose I was writing a SQLite interface that could write any form of LabVIEW data while maintaining variant attributes. I have to serialize the data somehow so the first attempt I just packed it into a variant then turned that into a string with flatten to string (since the variant contains the type info for what it holds I just need to use the type info for a variant to unserialize it). That failed with the first bug if I tried to store a variant with a attribute holding something down classed to the LabVIEW base object.
So instead of wrapping it in a variant I tried directly flattening it to a string and storing the type info from variant to flatten as a pascal string at the front of serialized data (of course this breaks if a LabVIEW object two variant levels deep is passed in). But that destroys variant attributes. So I tried wrapping that in a cluster then flattening the cluster (hence error two, and since it's indirect I can't wrap it in anything to avoid the problem).
So the current work around is to never store anything in the LabVIEW base object. So If I wanted a generic LVOOP container I would have to make a class for storable items then everything that can be stored would have to inherit from that.
I'm mainly posting since unknown bugs are rarely fixed, and this one is a bit obscure.

Logic for correcting strings with different barckets

can any one tell me the simple logic for correcting strings with different barckets
suppose say for eg.
(<{abc}>defgh) should evaluate to TRUE
(<{abc>} should evaluate to FALSE
Things to check is
1. number of opening brace and closing brace
2. Their position are correct or not
If the above two conditions are met than it is TRUE else FALSE
i guess string function with decode and lenght function or case should do but bit difficult to develop this logic in with sql
Thanks,
AAK

Time stamps to string with seconds

Good Day
Im writing a program for my DAQ system. Its required that my
data is saved with hours, mins and secs. The get date/time
string VI seems to only output a string with the date and with
hours and minutes.
How would I include the seconds into the outputed string.
Thank You for your time.

The vi has an boolean input 'want seconds' default is FALSE. Wire a TRUE and your done
For a more flexible output there is also the
Format Date/Time String Function
Owning Palette: String Functions
Requires: Base Package
Displays a timestamp value or a numeric value as time in the format you specify using time format codes. For example, %c displays locale-specific date/time. Time-related format codes include the following: %X (locale-specific time), %H (hour, 24-hour clock), %I (hour, 12-hour clock), %M (minute), %S (second), %<digit>u (fractional seconds with <digit> precision), and %p (a.m./p.m. flag). Date-related format codes include the following: %x (locale-specific date), %y (year within century), %Y (year including century), %m (month number), %b (abbreviated month name), %d (day of month), and %a (abbreviated weekday name).

Do you see something wrong in the code.Yes. Don't convert the signBytes to a String since (reading between the lines) it is a signature which is binary data and not characters.

Problem using DECODE() function with a Query of Queries

I
posted
on my blog about an issue I was having trying to use the PL/SQL
DECODE() function with a Coldfusion Query of Queries. This function
works fine when you query a database for information. However, when
you query another query, it seems that CF doesn't recognize it. I
got errors stating that it found a left parenthesis where it
expected a FROM key word. Here is a simplified version of what I am
trying to do:
quote:

<cfscript>
qOriginal = queryNew("Name,Email,CountryCode",
"VarChar,VarChar,VarChar");
newRow = queryAddRow(qOriginal, 5);
querySetCell(qOriginal, "Name", "Joe", 1);
querySetCell(qOriginal, "Email", "[email protected]", 1);
querySetCell(qOriginal, "CountryCode", "AMER", 1);
querySetCell(qOriginal, "Name", "Sally", 2);
querySetCell(qOriginal, "Email", "[email protected]", 2);
querySetCell(qOriginal, "CountryCode", "AMER", 2);
querySetCell(qOriginal, "Name", "Bob", 3);
querySetCell(qOriginal, "Email", "[email protected]", 3);
querySetCell(qOriginal, "CountryCode", "ASIA", 3);
querySetCell(qOriginal, "Name", "Mary", 4);
querySetCell(qOriginal, "Email", "[email protected]", 4);
querySetCell(qOriginal, "CountryCode", "EURO", 4);
querySetCell(qOriginal, "Name", "John", 5);
querySetCell(qOriginal, "Email", "[email protected]", 5);
querySetCell(qOriginal, "CountryCode", "EURO", 5);
</cfscript>
<cfquery name="qCountries" dbtype="query">
SELECT DISTINCT(CountryCode) AS CountryCode,
DECODE(states, "AMER", "North America & Canada",
"EURO", "Europe & Africa", "ASIA", "Japan &
Asia","") CountryName
FROM qOriginal
ORDER BY CountryCode
</cfquery>
<cfdump var="#qCountries#">

So running this returned the following error:
Query Of Queries syntax error.
Encountered "(. Incorrect Select Statement, Expecting a
'FROM', but encountered '(' instead, A select statement should have
a 'FROM' construct.
Does anybody know why this doesn't work? Is it just not
supported? Please note that I have also tried to use the CASE()
function instead of DECODE() and that resulted in basically the
same error. For now I an looping over my distinct query with a
switch statement and manually loading a new query with the data how
I want it. But it would be a lot cleaner and less code to have the
DECODE() to work. Thx!

DECODE() is an Oracle function, not generic SQL. Q-of-Q is a
very limited subset of SQL and lacks many functions and clauses
available in standard SQL, especially what you may be used to using
in your particular RDBMS.

String with embedded single quote

Hi, all. We're trying to pass a string from one procedure to another, which will then do an EXECUTE IMMEDIATE on it. However, there are single quotes withing the string, and they're driving us nuts! This is what the concatenated string should look like when passed to the pw_execDDL procedure:
insert into appimmunization.wsrprfs (inoc_id, proof, is_valid,proof_num) values ('MEAG', to_date('02-OCT-05','DD-MMM-YY'), 'Y',1);
Here's the concatenation process that doesn't work, and there are functions being called within the string:
chr_sql := 'insert into appimmunization.wsrprfs (inoc_id, proof, is_valid,proof_num) values (' || '''' || prm_inoc_id || '''' || ', ' || 'to_date(' || '''' || prm_proof1 || ''''||','||'''' ||'DD-MMM-YY'||''''||')' || ', ' || '''' || fw_is_proof_valid(prm_birth_date, prm_proof1) || '''' || ',1);';
pw_execDDL(chr_sql); /* call the procedure to do the EXECUTE IMMEDIATE */
Help! We've tried every combination -- using two single quotes together, three, and four, and still no luck. Thanks.

insert into appimmunization.wsrprfs (inoc_id, proof,
is_valid,proof_num) values ('MEAG',
to_date('02-OCT-05','DD-MMM-YY'), 'Y',1);
This statement can be made in a string with the following affectation:
chr_sql := 'insert into appimmunization.wsrprfs (inoc_id, proof, is_valid,proof_num) values (''MEAG'', to_date(''02-OCT-05'',''DD-MMM-YY''), ''Y'',1)';
Note please that each single quote in your original string must be specified using two single quotes and that is all. It is more readable and more easy to do it this way.
Michel.

Creating a string with hiearchical data

This is being done in Crystal 8 will all updates applied.
I have a database with records that are linked to a series of "folders" that are hierarchical in nature as shown below:
Folder 1:
     Folder 1.1
          Folder 1.1.1
Folder 2
    Folder 2.1
All of the folders can have data records attached to them.
The database represents the folder structure in a table with the following attributes:
Folder ID   (integer)
Folder Name (String) (such as "Folder 1"
Folder Parent ID (integer)
(other non-related fields)
If the folder is at the root level, then the value in Folder Parent ID is 0, otherwise, it is the Folder ID of the parent folder.
I need to be able to create a string field that displays the path for any given folder that I can insert into a group header or footer, or into a report header if the report deals with records in a single folder. Desired format for the string is:
"Folder 1> Folder 1.1> Folder 1.1.1"
I need to be able to display at least 6 levels of folder indentation.
I have tried several ways to create a formula that will reliably produce the desired string, and can get close, but cannot completely address the problem. My most successful approach was to put multiple instance of the table into the report and link the Folder Parent ID of one level to the Folder ID of the next level down and then use the data to build the string with a formula like this:
Local StringVar Result := {portfolio_master.portfolio_name};
local stringvar ExitLoop := "1" ;
if ExitLoop = "1" then
    Result := {portfolio_master_1.portfolio_name} + "> " + Result
else
    ExitLoop := "0";
if {portfolio_master_1.parent_id} NE 0 AND ExitLoop = "1" then // NE replaces Crystal not equal symbol which will not show
    Result := {portfolio_master_2.portfolio_name} + "> " + Result
else
    ExitLoop := "0";
if {portfolio_master_2.parent_id} NE 0 and ExitLoop = "1" then
    Result := {portfolio_master_3.portfolio_name} + "> " + Result
else
    ExitLoop := "0";
if {portfolio_master_3.parent_id} NE 0 and ExitLoop = "1" then
    Result := {portfolio_master_4.portfolio_name} + "> " + Result
else
    ExitLoop := "0";
if {portfolio_master_4.parent_id} NE 0 and ExitLoop = "1" then
    Result := {portfolio_master_5.portfolio_name} + "> " + Result
else
    ExitLoop := "0";
Result;
This formula works so long as the folder in question is exactly 5 levels deep. Changing the nature of the links(inner join, left outer join etc.) between the instances of the table in the Database Expert changes the data that is visible, but I can't find a combination that will show ALL of the needed information for all of the folders.
I understand that this is a brute force approach, and that there must be a different way to skin the cat. My preference would be to "walk the tree" with a loop structure, but I don't see any way to do the needed data look up within the loop.
Any suggestions would be greatly appreciated!
Thanks,
L. Jasmann

I have been working to adapt the code provided above to my application. Although I have worked with Crystal for quite a while, this is the first time that I have attempted to use SQL in Crystal... and it is just not working.. probably because I am no doing something very basic.
Here is the code as currently set up in the SQL Formula Editor. Only major difference from the code provided above is that the ID fields are integers instead of strings, and the field that I want to print out is a string field separate from the ID fields.... I have substituted the field names from the table I am referencing for the ones in the code above. The table that I am using has been selected using the Database Expert.
DECLARE @Value int, @pf int, @FolderPath VarChar(MAX)
SET @Value = "portfolio_master"."portfolio_id"
SELECT @pf = "portfolio_master"."parent_id" FROM portfolio_master WHERE "portfolio_master"."portfolio_id" = @Value
SET @FolderPath = "portfolio_master"."portfolio_name"
WHILE @pf <> 0
BEGIN
SET @Value = @pf
SELECT @pf = "portfolio_master"."parent_id" FROM portfolio_master WHERE "portfolio_master"."portfolio_id" = @Value
SET @FolderPath = "portfolio_master"."portfolio_name" + ' > ' + @FolderPath
END
SELECT @FolderPath AS FolderPath
When I test the SQL statement it errors out on the very first statement (the DECLARE statement). If I substitute a different statement in front of the DECLARE statement, it errors on that statement.
Here is the error that I get back. The database is using MS SQL Server.
Error in compiling SQL Expression:
Failed to retrieve data from the database.
Details: ADO Error Code: 0x80040e14
Source: Microsoft OLE db Provider for SQL Server
Description: Incorrect syntax near the keyword u2018DECLAREu2019,
SQL State: 42000
Native Error: 156 [Database Vendor Code: 156].
Any pointers would be greatly appreciated...

How Can I replace newScale Text Strings with Custom Values?

How Can I replace newScale Text Strings with Custom Values?
How can I replace newScale text strings with custom values?
All newScale text is customizable. Follow the procedure below to change the value of any text string that appears in RequestCenter online pages.
Procedure
1. Find out the String ID of the text string you would like to overwrite by turning on the String ID display:
a) Navigate to the RequestCenter.ear/config directory.
b) Open the newscale.properties file and add the following name-value pair at the end of the file:res.format=2
c) Save the file.
d) Repeat steps b and c for the RmiConfig.prop and RequestCenter.prop files.
e) Stop and restart the RequestCenter service.
f) Log in to RequestCenter and browse to the page that has the text you want to overwrite. In front of the text you will now see the String ID.
g) Note down the String ID's you want to change.
2. Navigate to the directory: /RequestCenter.ear/RequestCenter.war/WEB-INF/classes/com/newscale/bfw.
3. Create the following sub-directory: res/resources
4. Create the following empty text files in the directory you just created:
RequestCenter_0.properties
RequestCenter_1.properties
RequestCenter_2.properties
RequestCenter_3.properties
RequestCenter_4.properties
RequestCenter_5.properties
RequestCenter_6.properties
RequestCenter_7.properties
5. Add the custom text strings to the appropriate RequestCenter_<Number>.properties file in the following manner (name-value pair) StringID=YourCustomTextString
Example: The StringID for "Available Work" in ServiceManager is 699.
If you wanted to change "Available Work" to "General Inbox", you would add the following line to the RequestCenter_0.properties file
699=General Inbox
Strings are divided into the following files, based on their numeric ID:
Strings are divided into the following files, based on their numeric ID:
String ID File Name
0 to 999 -> RequestCenter_0.properties
1000 to 1999 -> RequestCenter_1.properties
2000 to 2999 -> RequestCenter_2.properties
3000 to 3999 -> RequestCenter_3.properties
4000 to 4999 -> RequestCenter_4.properties
5000 to 5999 -> RequestCenter_5.properties
6000 to 6999 -> RequestCenter_6.properties
7000 to 7999 -> RequestCenter_7.properties
6. Turn off the String ID display by removing (or commenting out) the line "res.format=2" from the newscale.properties, RequestCenter.prop and RmiConfig.prop files
7. Restart RequestCenter.
Your customized text should be displayed.

I've recently come across this information and it was very helpful in changing some of the inline text.
However, one place that seemed out of reach with this method was the three main buttons on an "Order" page. Specifically the "Add & Review Order" button was confusing some of our users.
Through the use of JavaScript we were able to modify the label of this button. We placed JS in the footer.html file that changes the value of the butt

Stepping through a query result set, replacing one string with another.

I want to write a function that replaces the occurance of a string with another different string. I need it to be a CF fuction that is callable from another CF function. I want to "hand" this function an SQL statement (a string) like this:   (Please note, don't bother commenting that "there are eaiser ways to write this SQL..., I've made this simple example to get to the point where I need help. I have to use a "sub_optimal" SQL syntax just to demonstrate the situation)
Here is the string I want to pass to the function:
SELECT
[VERYLONGTABLENAME].FIRST_NAME,
[VERYLONGTABLENAME].LAST_NAME,
[VERYLONGTABLENAME].ADDRESSS
FROM
LONGTABLENAME [VERYLONGTABLENAME]
Here is the contents of the ABRV table:
TBL_NM, ABRV    
VERYLONGTABLENAME, VLTN
SOMEWHATLONGTALBENAME, SLTN
MYTABLENAME, MTN
ATABLENAME, ATN
The function will return the original string, but with the abreviations in place of the long table names, example:
SELECT
VLTN.FIRST_NAME,
VLTN.LAST_NAME,
VLTN.ADDRESSS
FROM
LONGTABLENAME VLTN
Notice that only the table names surrounded by brackets and that match a value in the ABRV table have been replaced. The LONGTABLENAME immediately following the FROM is left as is.
Now, here is my dum amatuer attempt at writing said function: Please look at the comment lines for where I need help.
      <cffunction name="AbrvTblNms" output="false" access="remote" returntype="string" >
        <cfargument name="txt" type="string" required="true" />
        <cfset var qAbrvs=""> 
        <cfset var output_str="#txt#"> 
        <cfquery name="qAbrvs" datasource="cfBAA_odbc" result="rsltAbrvs">
            SELECT TBL_NM, ABRV FROM BAA_TBL_ABRV ORDER BY 1
        </cfquery>
     
    <cfloop index="idx_str" list="#qAbrvs#">      
    <cfset output_str = Replace(output_str, "#idx_str#", ) 
    </cfloop>               
        
    <cfreturn output_txt>
    </cffunction>
I'm mainly struggling with syntax here. I know what I want to happen, I know how to make it happen in another programming language, just not CF9. Thanks for any help you can provide.

One:
<cfset var output_str="#txt#"> 
No you do not need to create a local variable that is a copy of the arguments variable as the arguments scope is already local to the function, but you do not properly reference the arguments scope, so you leave yourself open to using a 'txt' variable in another scope. Thus the better practice would be to reference "arguments.txt" where you need to.
Two:
I know what I want to happen, I know how to make it happen in another programming language, just not CF9.
Then a better start would be to descirbe what you want to happen and give a simple example in the other programming language. Most of us are muti-lingual and can parse out clear and clean code in just about any syntax.
Three:
<cfloop index="idx_str" list="#qAbrvs#">      
I think you want to be looping over your "qAbrvs" record set returned by your earlier query, maybe.
<cfloop query="qAbrvs">
Four:
<cfset output_str = Replace(output_str, "#idx_str#", ) 
Continuing on that assumption I would guess you want to replace each instance of the long string with the short string form that record set.
<cfset output_str = Replace(output_str,qAbrs.TBLNM,qAbrs.ABRV,"ALL")>
Five:
</cfloop>               
If this is true, then you are looping over the record set of tablenames and abreviations that you want to replace in the string.

How to create a String with comma ?

Hi All,
I have a table with 10 records(employee name) and i have to make a string
with comma delimiter and at the end with "."
Can anybody tell me how to write a Java program for this ?
Thanks in advance.

// I believe the following example gives you the answer.
class stringEG {
     public static void main(String args[]) {
     String emprs[] ={"1","2","3","4","5","6","7","8","9","10"};
     String vempname = "";
     for(int i=0; i<emprs.length; i++) {
     if(i == (emprs.length-1))
          vempname = vempname + emprs[i] + ".";
     else
          vempname = vempname + emprs[i] + ", ";
     System.out.println("vempname : "+vempname);
Here dont assume that I asked you to get all the results and putting
it into the string arrays. But its a simple example to suit your requirement.
The half-way coding below answers your question, I hope.
vempname = "";
while (emprs.next()) {
if(emprs.isLast())
vempname = vempname + emprs.getString("empname") + ".";
else
vempname = vempname + emprs.getString("empname") + ", ";
// nats.

Disk File Sharing Switching from with base station password to with account

Ok, here's the situation. I have an external hard drive, with multiple partitions, connected to an AirPort Extreme (802.11n) and it is currently protected using the "With Base Station Password" option. I would like to switch that to the "With Account" option but when I do the files that are located on the disk no longer appear when a user connects. It will also work fine if I use the "With a disk password" option. So I am not sure why the files are disappearing for the users when they connect. Is there something that I am missing and is it possible to make the change.

I have the same issue.
Plus, in my case, two disks appear on my desktop, even though I have no partition. One is named the same as my disk, the other is named the same as the user account for the disk on the Airport Extreme.

i have a string with multiple lines inside it eg.
hello this is
my string with
mutiple lines inside it
how could i get it to print out line by line
iv used "\n" so it detects the new lines but it doesnt seem to work
this is my following code that doesnt seem to detect the newline
if(multiString.equals("\n")){
}

if(multiString.equals("\n")){But the whole string isn't an "\n" so this won't do. Again, much will depend on the current state of the String. You may need to split it based on the current line separator.

Parsing XML string with XPath

Hi,-
I am trying to parse an XML string with xpath as follows but I am getting null for getresult.
I am getting java.xml.xpath.xpathexpressionexception at line where
getresult = xpathexpression.evaluate(isource); is executed.
What should I do after
xpathexpression = xPath.compile("a/b");in the below snippet?
Thanks
String xmlstring ="..."; // a valid XML string;
Xpath xpath = XPathFactory.newInstance().newPath();
xpathexpression = xPath.compile("a/b");
// I guess the following line is not correct
InputSource isource = new inputSource(new ByteArrayInputStream(xmlstring.getBytes())); right
getresult = xpathexpression.evaluate(isource);My xml string is like:
<a>
<b>
<result> valid some more tags here
</result>
</b>
<c> 10
</c>
</a>Edited by: geoman on Dec 8, 2008 2:30 PM

I've never used the version of evaluate that takes an InputSource. The difficulty with using it is that it does not save the DOM object. Each expression you evaluate will have to create the DOM object, use it once and then throw it away. I've yet to write a program that only needs one answer from an XML document. Usually, I use XPath to locate somewhere in a document and then read "nearby" content, add new content nearby, delete content, or move content. I'd suggest you may want to parse the XML stream and save the DOM Document.
Second, all of the XPath expressions search from a "context node". I have not had good luck searching from the Document object, so I always get the root element first. I think the expression should work if you use the root as the context node. You will need one of the versions of evaluate that uses an Object as the parameter.

Can I encrypt a string with RSA encryption using DBMS_CRYPTO?

We have an web application that does a redirect thru a database package to a 3rd party site. They would like us to encrypt the querystring that is passed using RSA encryption. The example that they've given us (below) uses the RSA cryptographic service available in .NET. Is it possible to do this using DBMS_CRYPTO or some other method in Oracle?
Below are the steps outlined to use the key to generate the encrypted URL
2.1 Initialize Service
The RSA cryptographic service must be initialized with the provided public key. Below is sample code that can be used to initialize the service using the public key
C#
private void InitializeRSA( string keyFileName )
CspParameters cspParams = new CspParameters( );
cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
m_sp = new RSACryptoServiceProvider( cspParams );
//Load the public key from the supplied XML file
StreamReader reader = new StreamReader( keyFileName );
string data = reader.ReadToEnd( );
//Initializes the public key
m_sp.FromXmlString( data );
2.2 Encryption method
Create a method that will encrypt a string using the cryptographic service that was initialized in step 2.1. The encryption method should convert the encryption method to Base64 to avoid special characters from being passed in the URL. Below is sample code that uses the method created in step 2.1 that can be used to encrypt a string.
C#
private string RSAEncrypt( string plainText )
ASCIIEncoding enc = new ASCIIEncoding( );
int numOfChars = enc.GetByteCount( plainText );
byte[ ] tempArray = enc.GetBytes( plainText );
byte[ ] result = m_sp.Encrypt( tempArray, false );
//Use Base64 encoding since the encrypted string will be used in an URL
return Convert.ToBase64String( result );
2.3 Generate URL
The query string must contain the necessary data elements configured for you school in Step 1. This will always include the Client Number and the Student ID of the student clicking on the link.
1.     Build the query string with Client Number and Student ID
C#
string queryString = “schoolId=1234&studentId=1234”;
The StudentCenter website will validate that the query string was generated within 3 minutes of the request being received on our server. A time stamp in UTC universal time (to prevent time zone inconsistencies) will need to be attached to the query string.
2.     Get the current UTC timestamp, and add the timestamp to the query string
C#
string dateTime = DateTime.UtcNow.ToString(“yyyy-MM-dd HH:mm:ss”);
queryString += “&currentDT=” + dateTime;
Now that the query string has all of the necessary parameters, use the RSAEncrypt (Step 2.2) method created early to encrypt the string. The encrypted string must also be url encoded to escape any special characters.
3.     Encrypt and Url Encode the query string
C#
string rsa = RSAEncrypt(querystring);
string eqs = Server.UrlEncode(rsa);
The encrypted query string is now appended to the Url (https://studentcenter.uhcsr.com), and is now ready for navigation.
4.     Build the URL
C#
string url = “https://studentcenter.uhcsr.com/custom.aspx?eqs=” + eqs
