How do you pass knowledge ?

Dear Gurus,
When rolling off, a developer may be asked to hand over knowledge of codes developed to the next person.
Is there no way to hide knowledge during such a process given that codes can be read by any developer?
I like to know how to handover without actually handing over knowlege as much as possible.
Pls share with me this skill.
Thanks,
t.d

I agree totally. When we roll-off of a project and have "knowledge transfer", we go through a review process for each program. The developer meets with the client team lead and client developer. We do a code review and go over the functional and technical specification documents.
Some client contracts carry legal requirements. I have seen development objects listed as "type 1", "type 2", or "type 3". In some cases, the code is owned by the client and you cannot legally re-use it at any other site. Other cases declare the source code as "shared". You can re-use it at a new project. The third case may declare it is owned by the consulting firm or implementation partner. The client cannot share it with outside sources.

How do you pass XML as a URL param?
Thanks!

I don't know why I wasn't thinking about this when I made my
last post. If they're pasting some XML into a form, that's one
thing. But if they need to send XML to your site from their own,
you can setup a Coldfusion Component (CFC) as a Web Service to
accept XML through a WSDL call.

How do you pass shell scripts with cocoa?

How do you pass shell scripts with cocoa?

You asked for more detail -- I don't know if this is what you were referring to or not, but here's a little more detail on how to use the system() function if that's what you wanted to know.
As etresoft mentioned, the system() function can be useful for the kind of thing you are talking about. You will need to write the following statement at the top of your code if you want to use it:
#include <stdlib.h>
To use the system() function, simply put the command as you would write it in the Terminal between double quotes between the parenthesis. For example, something as simple as:
system("ls");
I don't what the practical use of the above statement would be, but it will run, and that's the general format for the system() function. So just put between the quotes whatever command you want to send.
Hope there was something helpful here.

How do you pass an ActiveX Variant from an external application to LabVIEW?

Background: I created a LabVIEW ActiveX server. I can access it with my external application (Matlab). I have a control variable in my LabVIEW executable. I want to use Active X to set the value of my control variable from my external application.
Documentation: The only reference in the documentation for this task is in the Using ActiveX with LabVIEW in the LabVIEW 2009 help. It simply says "Use the variant control and indicator to pass data to or from ActiveX controls." I also went through all the ActiveX examples in the example finder and did not find any vis that passed variables using ActiveX.
Questions:
What should my control variable look like in LabVIEW? Should it be a refnum, a variant, or a data type? Does it have to be wired to a vi connector?
Do I need to do any magic on this variable, such as change its properties?
How do I pass the value from my external application to the variable in my LabVIEW executable?
Thank you.

Hello Lyn,
The control variable should be a refnum and it would have to be wired to Automation Open with the correct reference.

How would you pass more than 255 args?

I have an SFTP program that currently is only passed a single file. I am modifying it so that it will loop though an array of files to simulate an mput command. Originally I was just going to call the program with each file to be transferred as an argument but noticed the 255 argument limit. I am looking at potentially having 1500 - 2000 files to transfer at one time. I am just looking for advice on how this should be designed. One idea that was forwarded to me was to just create a listing of the files on the server and use that list file as my argument. Would this be the best approach for this issue?

I see no reason why you need an argument for every file.I would not necessarily need one for every file. Prior to our needing to use this for multiple files, it was easy enough to pass in one file as an argument. That is my question, how would you try to pass in a long list of files?Let's establish what you are concerned about. The 255 argument limit is on method signatures. From what you're saying here, you're talking about arguments being passed into your application from, say, the shell. Am I right?Correct, please see my clarified post. From what I have tested, the 255 argument limit appears to exist even for arguments passed to main.Ah, but arguments passed to main from the command line are passed into main as a single array of Strings, no matter how many of them there are. I have no idea what the limit on those is, but an array can hold millions of elements. I expect your shell will moan about that many, though.
As I see it, you have a few choices. Unless these files are all in different, arbitrary directories, you can specify a list of directories for your app to search. Or you can pass them all in one at a time, and see how you go. Or you can list them in a text file, pass that to your app and have it work them out. Or write a script that invokes your app multiple times. What you don't need, is a method that takes each file as an argument.Thank you for walking me through this. Would you mind telling me which way you would lean if you were designing this? The files will all be in a single directory on the server and I would not like to invoke the app multiple times as it creates a connection during each invocation. They're all in the single directory. Ok, are all the files in that directory to be transferred? If so, I'd just pass the directory name to the app, and have it iterate over all the files. If it's only to be certain ones, how do you know which ones? Is there some regex or filtering you can do on the command line?
If you are interested, the 255 argument limit for main that I tested was from this article:
[http://www.javaspecialists.eu/archive/Issue059.html|http://www.javaspecialists.eu/archive/Issue059.html]
It does die at 255 using Java 1.5.Like I said, arguments to a method are thus limited. But the args passed to an app are passed to main as one argument - an array. In short, that article is not relevant to your problem.

JavaScript: How do you pass the currently active doc to a dialog in a menu item?

I'm using Adobe Acrobat 11.0 Standard on Windows 7, and I'm having trouble with the menu item that I'm creating. The menu item calls a dialog that prompts the user to select a page in the currently active document. The problem is, I can't figure out how to pass the currently active document to the dialog. I scoured the rest of the documentation, did searches on Google and here in the Adobe forums, but haven't turned anything up. The AcroJS API gives the following solution (found under app/methods/execDialog):
This function attaches the Doc object to the dialog box, then passes the dialog box to the app.execDialog method. The dialog4 object and this function can be at the document level.
   function dotheDialog(dialog,doc)
        dialog.doc = doc;
        var retn = app.execDialog( dialog )
Finally, the following script can be executed from a mouse-up action, for example.
    dotheDialog( dialog4, this );
I did this exact thing, but in the dialog, the value of this.numPages still comes out as undefined, indicating that the current document still hasn't been passed. My own code looks like this:
function dotheDialog(dialog, thisDoc){
    dialog.doc = thisDoc;
    var retn = app.execDialog(dialog);
app.addMenuItem({
    cName: "Test Dialogue Box",
    cParent: "Edit",
    cExec: "dotheDialog(templateDialogue, this);"
where templateDialogue is the name of my own dialog, rather than dialog4. I'm not sure what the retn variable that they declare in the documentation is for, but I've tried it with and without that part, and it doesn't seem to make a difference. Does anyone know how to do this?

Sorry, here it is. It's also just a small modification of something directly from the API, which is why it still has the date bit in it.
var templateDialogue = {
initialize: function (dialog) {
    // Create a static text containing the current date.
    var todayDate = dialog.store()["date"];
    todayDate = "Date: " + util.printd("mmmm dd, yyyy", new Date());
    dialog.load({ "date": todayDate });
commit:function (dialog) {    // called when OK pressed
    var results = dialog.store();
    var inBounds = (parseInt(results["tPag"]) < this.numPages);
    if(!inBounds){
      app.alert({
        cMsg: "Please enter a valid number for the page from which to make the template." +
        "\n" + parseInt(results['tPag']) + " = parseInt(results['tPag']) !< this.numPages = " + // I put this in to see the value of this.numPages,
        this.numPages,                                                                           // and it continues to be undefined.
        cTitle: "Page out of Bounds",
        nIcon: 0, nType: 0
    }else{
      var nButton = app.alert({
        cMsg: "Your template is named " + results["tNam"] + " and is made from page " + results["tPag"],
        cTitle: "javascript",
        nIcon: 3, cType: 0

Side Question: Out of curiosity, how would you abort if the user clicks cancel? I get the feeling that they don't cover it because it's something you're supposed to already know how to do, but...I don't. Would you just put whatever action you want to take into an if ( button == "Ok" ) type statement so that cancel does nothing?

How do you pass the data from a SBO process to a crystal report laout

Hi Everyone
Can someone please assist or direct me to documentation that could be of help.
I do production orders in SBO.
I have a crystal report that I have imported as a layout to print these production orders.
The report was developed the normal way, linking to the tables and returning data(all data for all production orders ever done)
The production print option is set to make use of this layout.
What I would like to see is that when I create production order 12345 and click on print preview I get the data of the mentioned order only displayed in my crystal layout(that is set to default)
What I get however is all the data from the tables.
Where am I going wrong. With my design already or is there a different way to pass the data to my report/layout direct from my SBO production order screen
This is quite urgen
Regards
Burger

Hi All
The solution i was looking for is:
In Crystal create the parameter called DocKey@
This is recognized by sap and the active document number is passed to the report layout.
In crystal itself also do a filter {<Table>.<Column Name>} = {?DocKey}
So simple once you know how.
Hope this help someone else that is as stuck as I was.
Regards

How do you pass more than 3 items to another page via a Column Link?

I know this is a simple question, but I don't see it covered in the manual.
I have a report on page 1, when the user clicks on a column link, I'd like to pass 4 items to the page that is called.
The Column Link area allows you to specify 3 items. How do people normally accomplish this?
Do you somehow use page zero? Do you use Application Items for this purpose?
Also, can someone recommend a good APEX book to supplement the manuals?
Thanks

Oh Varad I didnt know this, Thanks for a new tip ;)
Just change the target to URL and enter a simple statement
in the URL section
f?p=&APP_ID.:50:&SESSION.:10:&DEBUG.::P50_item1,P50_item2,P50_item3,P50_item4:value1,#column_name2#,#column_name3#,#column_name4#
Use value when u know a fixed value to be passed
and column names on the same report can be passes by using #column_name#
Hope this helps
Thanks

How do you pass a variable from one form to another

Sorry, I am new at this.
I have an ID on one form and I want to pass it to another form and then populate a text field on the second form. How is this accomplished.

There are various ways to accomplish this depending on your applications' needs.
Read up on the manual, especially on session state management http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10499/concept.htm#CIHCFHBD
This will get you familiar with the basics of url syntax and and session state after which you will have no problem implementing what your asking

How do you pass "struct" in an AJAX call URL? (CF11)

Quote from CF11 documentation: "Note that "struct" is also available to be accessible through an AJAX argument. Now you can pass struct in an AJAX URL to serialize a query object as struct."
How? An example URL would be handy.

"To serialize a query object as struct" overstates the case. You can serialize a struct, as well as a query, for sending by means of URL.
For example, create the following 2 CFM pages in the same directory.
testpage1.cfm
<cfdump var="#url#">
testpage2.cfm
<cfset myStruct = structnew()>
<cfset myStruct.myFirstKey = "uno">
<cfset myStruct.mySecondKey = 2>
<cfset myStructSerialized = serializeJSON(myStruct)>

<cfquery name = "getBiololgyCourses" dataSource = "cfdocexamples">
    SELECT Course_ID, Dept_ID, CorNumber,
    CorName, CorLevel
    FROM CourseList
    WHERE Dept_ID = 'BIOL'
    ORDER by CorNumber asc
</cfquery>
<cfset biologyCoursesSerialized = serializeJSON(getBiololgyCourses)>
<cflocation url="testpage1.cfm?myVar=#myStructSerialized#&biologyCourses=#biologyCoursesSerialized#">

How do you pass an array of characters using the DLL functions

I have exported C code into my DLL and I want to know how to pass an array of characters using LabVIEW.

Mont;
If you want to pass a string from LabVIEW to your dll, and you do NOT change size of the string, you can use a C String pointer (CStr), which is equivalent to (unsigned) char *.
If you do modify size of the string, pass string as a LabVIEW structure (LStrHandle).
The example "Passing a Variety of Data Types from DLL to LabVIEW" is an excellent starting point. Also make sure you check the manual "Using External Code in LabVIEW".

How do you pass vi references from one event to another

I have a vi which gets vi references (thereby loading the vi's into memory) for all the vi's in a given directory when a user clicks a button on the front panel. To do this I use an event structure. My question is whether it is possible to have another event (user button on the front panel) which unloads the vi's from memory. I have tried passing the vi references that are initially generated to the close reference function but whenever I do I get a 'vi reference invalid' error. Does this have to do with trying to pass the vi references between one event and another? If I use a local variable simply pass a reference to another indicator and then probe it, the originally-generated refnum and the local vari
able refnum match up. However once I try to wire that same indicator to the close reference function I get the 'vi reference invalid' error. Is there a different/better way to unload the vi's from memory based on a user button click? Any suggestions would be welcome.

Several problems with your code:
1... Bad idea to use lights as buttons. Yes it can be done, but it's not "natural".
2... If you've gotta do that, set their mechanical action to "LATCH WHEN RELEASED"
3... Because of #2, you are getting TWO copies of every array when you click the LOAD VIs light (er... button).
4... No need for the conversion from path to string and back - use BUILD PATH to append each file name to he folder path.
5... Set the BROWSE OPTIONS on your PATH control to EXISTING DIRECTORY to allow browsing of directories, not files.
6... Your code doesn't care whether the file is a .VI file, or a .ZIP file, or a .TXT file, or what. Use the PATTERN input on the LIST function to discriminate.
7... Your code is only storing the latest refer
ence, not the array of references.
8... An ERROR DIALOG on the OPEN REFERENCE function will tell you that you're getting an error. Why? You are asking to prepare a non-reentrant VI for reentrant execution (why use options = 8?)
9... Because of #8, the latest VI reference is invalid.

How do you pass a variable from one page to another thru a button

I have a page that has a button that goes to another page and allows the user to create a new record related to the data on the previous page.
The first page is a master, while the second page is a detail. I need the primary key from the first page to update a column in the detail page.
How do I get the primary key in the second page and how do in put the data in the correct column?

Hi Nielsen,
The master detail form should handle everything for you already...Select all rows in each table but only display the records besides the primary keys. Try creating a new master-detail form with this idea, don't bother trying to change some other page.
