How to write into multicolumn listbox during runtime?

Hi,
I am able to edit into multicolumn listbox. But i am not able to write into empty boxes... How to do that???
Regards,
Amit

Hi Amit,
Have you initialised the item names with any default values? If not try initialising the item names to a 2D size that will be large enough for you're requirements. Once this size is set in edit mode you can't enter data at runtime outside of this initialised area.

How to update cgicmd.dat file during runtime?

I'd like to know how do update cgicmd.dat file during runtime. For example, I run a report one.jsp as
http://<machine>:<port>/reports/rwservlet?one.jsp&USERID=uid/pwd@db&DESTYPE=cache&mode=bitmap&desformat=htmlcss
within this report there is a hyperlink to open another report named two.jsp.
before creating this hyperlink, I'd like to update cgicmd.dat file with passed in userID, pwd, and connection, so two.jsp can use this key for userinfo
so I can create hyperlink as follows
srw.set_hyperlink('/reports/rwservlet?report=two.jsp'||
'&cmdkey=userinfo&DESTYPE=cache&mode=bitmap&desformat=htmlcss');
Thanks

To my knowledge the cgicmd.dat is only read when the OC4J starts, so you would have to come up with another solution. Using Single-Sign-On (SSO) is quite a good idea, and it's there for cases like this.

Entries into Multicolumn Listbox/Safing Data in .txt-file

Hello. I haven't found anything helpful for my problem or better to say problems. I have to do a task that I have no idea how to solve. It isn't helping that I was never good with programming. Here is what I have up till now:
I want to write seven strings indivudally into a multicolumn listbox with seven columns. The first shall be a running number, increasing for every row. For this I'm using right now a Case Structure. And there is my first problem. I don't know how to realize that whenever a row is completed the next string is written into the next row instead of overwriting one in the completed row.
This has to go one for as long as the user wants to. Then there has to come a Pop Up Window - if that's the correct term - and shall ask the user if he/she wants to safe the created list into a textfile. And that's my next problem. I have no idea how to program that.
I know it's probably rather easy to program these things in LabVIEW 8.0 (which I'm using) but as I've already said I'm anything but good in programming at all and to make things even more complicated I don't want to do this task, therefore not putting all my energy into it as a result.
Please, can someone here help me?

Does it have to be a multicolumn ListBox?
Seems like a table might be more appropriate, if it's only for display purposes.
Either way, you need to use a FOR loop inside a FOR loop to generate a 2-D array of strings.
The INNER loop generates the strings for each column in a row, the OUTER loop generates each row.
You wire the 2-D array directly to a TABLE indicator, or to the ITEM NAMES property of a ListBox.
Attached is a pic.

Filling large array into multicolumn listbox

Hi,
I need to fill a multicolumn listbox with a large array. I feed a 2D array into the ListNames property. The problem I am having is that if the array is large (+1000) it is taking forever to update the itemnames. Is this because the listbox is going through a resize? Is there someway to intialize the ItemNames array to speed up the insertion. It is also slow if the next array insertion (overwrite) is a small array.
thanks Michael

Hi Michael,
Please take a look at the attached VI.
This VI allows the user to programmatically (during run time) write data to a multicolumn listbox. The VI uses the control reference to a multicolumn listbox, so this VI will work on any multicolumn listbox. The VI has inputs for the 2D array (of strings), and a start location (row and column) where the zeroth (top left) element goes. The VI returns the end row and end column of the multicolumn listbox. This is useful for writing successive entries to the listbox.
In this vi, I am currently writing a 1000*10 2D array to a multicolumn listbox and it runs very fast.
Regards,
Ankita A.

How do I create multiple objects during runtime?

I don't know how to create multiple objects during runtime, here's my problem:
I get a String as input. Then I create an object called newobject. I put the object in a hashtable with the above string as key.
Then comes the problem, in order to create a new object, I have to rerun the same class, which uses the same name (newobject) to create a 2nd object. Now my hashtable doesn't reference to my 1st object anymore...
Is there anyway I can fill up the hashtable with different objects, and make each key point to each object it was supposed to?
For those who want to see a bit of the program:
public class PlayBalloon{
public Hashtable ht = new Hashtable();
for(){
Balloon pB = newBalloon;
newBalloon=new Balloon(pB);
ht.put("Some input from user", newBalloon);
for(){
ht.get(s).draw;<= s=string, draw=own meth. in Balloon
}

I think i can see the problem that you are having. You have, in effect, duplicate keys in your hashtable - ie, two strings used as keys with the same name.
The way that a hashtable works is as follows...
When you ask for a value that is mapped to a key it will go through the table and return the first occurence it finds of the key you asked for. It does this by using the equals() method of whatever object the key is (in your case it is a String).
If you cant use different Strings for your keys in your hashtable then i would consider writing an ObjectNameKey class which contains the String value that you are trying to put in the hashtable and an occurrence number/index or something to make it unique. Remember to override the equals method in your ObjectNameKey object or else the hash lookup will not work. For example
class ObjectNameKey {
    private String name;
    private int occurence;
    public ObjectNameKey(String name, int occ) {
        this.name = name;
        this.occurence = occ;
    public String getName() {
        return name;
    public String getOccur() {
        return occurence;
    public boolean equals(Object o) {
        if (!(o instanceof ObjectNameKey)) {
            return false;
        ObjectNameKey onk = (ObjectNameKey)o;
        if (onk.getName().equals(name) && onk.getOccur() == occurence) return true;
        return false;

How to determine the target system during runtime of a Generic DS?

Hi Experts, good afternoon.
I am coding a Generic Extractor using Function Module. I have to select the field TIMESTAMP on table ROOSPRMSC. To do so, I need the value of RLOGSYS that is the BW system that is calling the Extractor.
Do anybody knows how to determine via ABAP the RLOGSYS (Remote Logical System) during the runtime of the Generic DataSource Function Module?
The table ROOSPRMSC keep the TIMESTAMPs values of the last delta upload for each DataSource and for each BW target system. As I have 2 BW's loading data from the same SAP ECC system, I need to know, during runtime of my Generic DataSource, the actual system that is requesting the delta. That's the reason why I need to know the BW's logical system name that is "runnig" the delta InfoPackage.
Plese, help!!!
Thanks in advance!
Leandro Vani

Leandro,
The calling program of your FM should have a local variable I_RLOGSYS which is populated with the BW server ID.
If you don't know how to access a variable in a program that is in call stack using field symbols, search SDN.
I haven't tested this, so you may have to explore a little.
Good luck.

How to write 'into' a PDF-document ?

hi there,
i have a new small project to do with the following problem:
i get a file (text-file) with invoices from an external system.
I want to 'overlay' this file with a form, which is a PDF-document.
the question is: is it possible to write 'into the PDF'-form the contents of the text-file ? if yes, how is it possible ?
regards, Martin

well,
this is not what i need, sorry
i don't want to convert the text-file into a PDF-file.
i have an existing PDF-file (a FORM with all the overlay, like graphics, company-logo, etc....). and i have a text file. and i want to 'merge' the text into
the pdf-file.
regards, Martin

How does one empty an array during runtime with a front panel switch

I can 'empty array' from the front panel during runtime but I want to empty all arrays (20) from my vi with a front panel switch (see screenshot). I have used replace array subset and reshape array with no success. Any help would be appreciated

Hmm... You can empty an array by reshaping it or by assigning a constant empty array - using local variables or properies of the original control (see attached example... hmmm... not the best one ). May be you can attach a part of your code to see what is better to do in the given case.

How to run a Jar file during runtime

Runtime.getRuntime().exec("javaw -jar MYJAR.jar");was what I used to run the jar originally, and it worked. Recently I created an installer for my program, where the user runs a batch-file shortcut which launches the main application. Because the main application is launched from the desktop, rather than directly, the "user.dir" property is different which makes the above code not work. How do I get the name of the folder that contains the running java application?
Thanks

You don't. You fix the installer so that it puts the correct working directory into the shortcut that it creates.
