Populating a Drop-Down Menu via xml in php

I am new at programming. I am looking for a way to link a drop menu to 3 drop down menus dynamically. In other words, the 3 ddm's will have the same options according to the value selected in first ddm. Can someone provide a tutorial for this? Also, i am using php to pull the data for those ddm's from xml file.
Thank You

php is server side... so you want user to choose option from dd menu #1, reload the page to populate dd menu #2 (process on server via php), choose option from dd menu #2, reload the page again to populate dd menu #3 (process on server via php), then finally choose option from dd menu #3 and then after reloading the page three times already (once for initial load and two more time for each subsequent server process) load the page for a fourth time to process the entire form entry? Whoa daddy... that's a lot of page loads.
Just want to be clear of your desire. I don't think you'll find many tutorials for the mentioned method. There are many, many three tier drop down menus in javascript that provide client side processing without page reload.

Populating a Drop down menu JSP form

How to go about populating a drop-down form from Oracle Database using JSP?
I have the connecting to the Oracle Database running. I also can query forms, but i can't create a drop-down menu form.

Start the dropdown box with the regular select tags "<select name=this>"
Then open a JSP block and get a resutlset, loop through the resultset and and put the values from the resutlset into the <option> tags for the HTML.
Example
out.println("<option value=\"" + rs.getString(1) + "\">" + rs.getString(1) + ">");
Then close the loop and that should populate a dropdown within the html form.

How do I get the VISA resource drop down menu to be auto populated in my stand alone application (exe file)?

Hi all,
Here's a hopefully simple question.
I am building an application (i.e. an exe file) from a simple program which use VISA to read and write to a RS-232 com port. When I run it before building the application everything works fine and the VISA resource control, which is a drop down menu, is automatically populated with available com ports. When I run the application on a computer without LabVIEW installed nothing appears in this window. I have made an installer which includes NI LabVIEW Rutime Engine 8.5, NI Measurement & Automation Explorer 4.3 and NI-DAQmx 8.6.1. Is there anything else I need to include? Any specific settings I need to do when I build the exe-file?
I use LabVIEW 8.5.
Thank you.
Solved!
Go to Solution.

DAQmx is only for NI DAQ cards so I'm not sure why you installed that. The driver for VISA applications is NI-VISA (surprise!)
Add the NI-VISA run-time to your installer.

Most of my library consists of h.264 videos wrapped in the m4v format, which my converters (Handbrake & mkvtools) says is the Apple TV format. Today I tried coverting a few to mp4 (for iPad) instead, so that I can watch them on multiple devices, but I'm running into the same problem with those that you are.
I tried resetting my ATV as the other responder suggested, but that hasn't helped. I'm still unable to watch h.264 mp4 files, while h.264 m4v's are fine.

Selecting the XML data from a drop-down menu or links

Hi, I have this page:
http://www.georgeglazer.com/prints/nathist/botanical/volckinv/volckinv.html
There are prints of lemons/limes and prints of oranges. I
want to have the visitor select which kind of fruit from either a
drop-menu or from two links that look something like this:
Lemons/Limes | Oranges. Looking at other help docs I found the
region/state mapping demo at
http://labs.adobe.com/technologies/spry/samples/data_region/StateMappingSample.html,
and copied the code and tried to modify it. But I don't really
understand the technical shorthand of the help docs (an ongoing
problem I have with the Spry documentation) and I couldn't find the
XML docs that the region/state mapping demos are based on so I
couldn't see how they were set up.
I got as far as this: nothing loads initially when you open
the page (I'd like the lemons to load), but if you select Oranges
from the drop-down menu you see the oranges, and THEN once you've
done that, you can select Lemons/Limes in the drop-down menu and
see those. I have three XML files I've been playing around with to
get this to work: lemons.xml, oranges.xml and inventory.xml, which
combines the two.
I also suspect region/state mapping might not even be exactly
what I'm trying to do here, but I can't figure out from the
documentation exactly what this thing I'm trying to do is called. I
know the photo album demo accomplishes something similar, and I
could do that, but it seems way more complicated than what I need
here (right?). Help will be appreciated!
Thanks,
Helen

I made a different test using the file
http://www.georgeglazer.com/prints/nathist/botanical/volckinv/inventory.xml
and
http://www.georgeglazer.com/prints/nathist/botanical/volckinv/volcktest.html
where I sent up the inventory xml form like one I found in the
Nested XML Data documentation where you have item ids and types, so
all the oranges and lemons are in one XML document (which I'd
prefer).
Here's an abbreviated version of the inventory.xml:
<inv_items>
<inv_item id="1" type="lemon">
<name>Lemons and Limes</name>
<title>Cedro Ordinario</title>
<plate>116a</plate>
<fullimage>pl116a.jpg</fullimage>
<tn>pl116a-2.jpg</tn>
</inv_item>
[and more lemons follow]
<inv_item id="19" type="orange">
<name>Oranges and Others</name>
<title>La Zucchetta Imperiale</title>
<plate>138a</plate>
<fullimage>pl138a.jpg</fullimage>
<tn>pl138a-2.jpg</tn>
</inv_item>
[and more oranges follow]
</inv_items>
What I'd like to do is display the names "Lemons and Limes"
and "Oranges and Others" and when you click on "Lemons and Limes"
you see only the thumbnails for lemons and limes, and when you
click on "Oranges and Others" you see the thumbnails for only
those. I'd like the Lemons and Limes to be selected when the page
is opened.
Help greatly appreciated!

Display XML in a drop down menu

Hi,
I've got Dreamweaver CS3 and I'm trying to display some XML
data.
I've loaded the XML in both XSLT and Spry, but I can't seem
to disply it in the way that I want (i.e. in a drop down menu).
Any help would be great.
Cheers.

Insert a Spry region. With your cursor inside the Spry
region, click the
Spry Repeat List button on the Spry tab of the Insert bar.
Choose SELECT
(Drop-down List) as Container tag. In the remaining three
options,
select the Spry data set, and the names of the columns you
want to be
used for the menu labels (Display Column) and values (Value
Column).

Populating drop down menu based on selection in other dropdown

Hi
I want to know a solution for populating 2 drop downs. The scene is that once the user has logged in he has to select a REGION. The options in region are EAST, WEST, NORTH, SOUTH, ALL.
On selecting the region a second drop down gets populated with the dealers of that particular region.
DROP DOWN 1 : REGION > NORTH
DROP DOWN 2 : DEALERS > ALL DEALERS IN NORTH.
Someone n Everyone please help me urgently.

ok here's what your servlet would look like:
public class getDealers extends HttpServlet {
    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws javax.servlet.ServletException, java.io.IOException {
        // get the region selected from the form1
        String region = request.getParameter("region");
        if(region != null) {
            //calls a static method which selects dealers from a database or whatever you have to do to get the list
            Collection listOfDealers = Dealers.findDealersByRegion(region);
            //puts the list in the session.
            request.getSession().setAttribute("listOfDealers", listOfDealers);
            // server side forward back to the page
            RequestDispatcher rd = this.getServletContext().getRequestDispatcher("/mypage.jsp");
            rd.forward(request, response);
        else {
            //handle error
}Hope this helps
good luck!

AD Site names are not populated in Collection criteria drop down menu...

I tried to create a collection based on AD Site name. Collection creating wizard on the membership rules tab, query rule properties, edit query statement (system resource), criteria tab, criterion type is simple value, System resource - Active
Directory site name, operatör is equal to Vlaue... there is no AD site names appear in this drop down menu, just one of the 20 sites appear. I already run the system discovery, and create Automatically boundary for the each sites. And also create
the Bpoundary groups...
Thanks,

Yes, I know this is an old post, but I’m trying to clean them up.
Did you solve this problem, if so what was the solution?
Without the query that you are using it will be hard to troubleshoot this issue but my guess is that the PC that belong to those AD site have not yet be inventoried. Check your Heartbeat and Hardware inventory.

Can you display a calendar in a drop down menu to select a date

I would like to display a calendar in a drop down menu like in
outlook's calendar appointments. Is this possible with forms
and how can it be done. I haven't been able to find anything in
the book I have. Any help would be appreciated
Thanks
Jim

I am sure this is possible. There is a calendar object on the Forms and Demos CD but I have created my own calendar just using a single form that is called from every date field.
Create your calendar using a single date item that is populated by a parameter - this will be either the date from the field or sysdate. Create the other elements of the calendar as calculated items based on the first item +1, +2 etc. Use a when-mouse-click trigger to get the user's selection and pass it back to the date field via a global variable or a shared PL/SQL library.
To make it more like the Outlook calendar you will have to add a button next to every date field and add code to position the calendar according to the field position. You may prefer not to bother to do that - I just open the calendar centrally on screen and activate it using key-listval and/or a pop-up menu.
Hope this gives you an idea.

Trying to alter drop down menu

I am creating a form that uses a lot of drop down menus and I am trying to have the drop down show the descriptions and have the box actually populated with a part number instead of description. I am not against XML coding if needed I am new to it but have played around a little bit. Any ideas or direction would be much appreciated thanks.

Yes. Put the descriptions in the drop down menu and then specify values in the binding tab. In the exit event for the drop down menu put the code (in formcalc):
if ($.rawValue == 1) then
$.formattedValue = "109323" // put whatever the part number is in here
elseif ($.rawValue == 2) then
$.formattedValue = "109324" // etc
endif
the rawValue is the value of the option the person has chosen in the menu and the formattedValue is what the box will show once the exit event has executed.

How can you change a drop down menu's selection in a case statement?

Hi,
I am trying to an array finding vi. This VI will take an existing xml file and after the user has selected his/her equipment, input, output, and frequency it will put all of those options into a string and search the xml file for that exact array name and display it on an output screen. The problem I am having is that my input and outputs selection needs to be a little different depending upon the equipment selected. I thought that I could use a case statement to change the input and output selectable options, but I have run into many snags with it. For one everytime I place a new Input and Output drop down menu in the case statement it wants to place a new one in the front panel (I only want one input and output not three I have two inputs and outputs hidden right now). I believe I am using the case statement wrong... Can anyone help change my input and output selectable options depending upon the equipment selected. Attached is my xml file, Array Find.vi (the original one), and Array Find_Test.vi (this is the one I am trying to modify).
Thanks,
dlovell

Hi dlovell,
There are 2 key things I'd recommend for the code - using property nodes to edit the strings in the combo boxes. Something like the following snippet:
Also, check your CPU in task manager when running the code. It will eat a whole core of your machine (25% quad core, 50% dual, 100% single) - that is because you are running the while loop and polling the control as fast as Windows will allow you to. Using Event Structures is a much more efficient way of working in this example.
