VI Keydown event interferes with menu selection

My application requires that the user log a data point with a spacebar pressed. To do this, I want to use the Key Down event at the VI level. However, I find that when I include this event it disables the keyboard's Alt- menu selection, even though I'm passing all the parameters through KeyDown unchanged. I've included a skeleton VI that exhibits this behaviour. Has anyone else run into/overcome this problem?
Thanks,

Instead of using keydown, use keyup. I have written the attached VI to decode the scancodes on my computer so that one can tell what key was pressed. Unlike with keydown, this method allows the alt-keys of the window to work and it will indicate a larger number of keys.

Other events interfere with abort for state machine started by an event

In the attached VI there is a state machine that is triggered by a boolean “start” change event. There is also a boolean “stop” that stop the state machine, a numeric “voltage” that has an event handler and a boolean “exit” that has an event handler.
The stop button works as expected unless if the voltage value is changed before the stop button is pressed. I was thinking this might be because there is an event for the voltage value change but there is also an event for the exit button value change and the problem does not occur if the exit button is pressed before stop.
If anyone could explain the reason I am only running into the problem with the voltage value change and/or how to properly implement the stop/abort function I would appreciate it!
Thanks,
Dave (LabVIEW 7.1)

Well that certainly solves the problem I was having! The case in a while in a case in a while reminds me of the 10-level deep if statements I used to end up when starting C programming. I guess the inner case/while are required for the state machine and the outer while is required for the Producer / Consumer. I always find myself thinking in terms of "if/then" statements and the case/comparison took the place of that.
Regardless, problem solved. If anyone has tips on how to make it (attached) look better, please post them!
Lynn, I wasn't quite sure about your instructions on passing the exit and stop commands through the queue. I went with the idea of keeping the long-running loop separate. I know I still have a bit more to work out such as use of exit button while state machine is running, and the stop button only works in between state machine iterations.

My mouse out event interferes with my "clicked" animation...

I created a page that contains several buttons. Whenever you mouse over any given button the graphic on the page updates to new information. Everything works fine at the level. Then, I created a click event on one of the
buttons, that makes an animation play on top of the information.
Everything works fine except whenever you click on a button, the animation will play...BUT as soon as the cursor "mouses out" (intentionally or not) the whole animation goes away and the page goes
to default ( as if you've moused out without ever have clicked the button )
I'm a complete newbie and know very little about Javascript and zero about jquery. I thought I could do a "workaround" and do it very simply but none of my "simple" solutions work.
I don't want to re-think or re-design the page but I may have to.
thanks

Mobile site using an accordian panel with menu selections

I watched the adobe muse video here is the link http://tv.adobe.com/watch/creative-suite-podcast-designers/how-to-create-a-dynamic-sliding -menu-for-your-mobile-website-in-adobe-muse/
In the demo, when you preview it mobile site, the menu is not displayed and when you tap th emenu, the accordian menu displays and pushes all the content down and then when you close it, pushes it back up.
I created a similar test mobile site. But, when I preview it the menu always appear on start up and the content is not pushed down or up when the menu is activated or closed. I noticed that the options on the accordian widget in the video are different than in my MUSE which is V7.1 build 329. There is no close all initially check box. Instead I have an overlap item below check box.
So my question is what do I need to do to get this to work as per the video.
Thanks-Bryan

Hello,
I think there may be an issue in how your model/Accordion Menu was configured. What insert option are you using? Your destination should only be 'one' row OR 'one' column at the most.
Thanks,
AJ

How to programmatically signaling Menu selection (User)

I have an event case handling Menu selection(User) event. Now I wish to programmatically signaling the Menu selection (User). Is that possible in LV?
WT
LV2013SP1

Well then you could have a state machine, where you go to the "Menu Selected" state when the event is generated. Or you can choose to go to that state in your application whenever you want. Now you don't have code duplication and have once case that handles doing the work, and you can get there from multiple methods.
Unofficial Forum Rules and Guidelines - Hooovahh - LabVIEW Overlord
If 10 out of 10 experts in any field say something is bad, you should probably take their opinion seriously.

I am using the "Menu Selection With Events.vi" example alongside other while loops, When I select exit from the new menu it stops the other while loops but not the menu/event while loop

The event driven menu example works fine and I've integrated it into my application. I have built in simple local vars to link menu selections to existing GUI buttons. The problem is that I cannot get the File-Exit menu option to switch off/terminate the application. The [1] "Stop": Value Change panel of the event structure simply switches off the other while loops but leaves the event while loop running. Add a while loop to the axample using a local var from the event while loop to terminate 2nd while loop to get the effect.
Help appreciated, Chris

Attached you will find a modified version of your VI.
I documented what I did on the block diagram.You were right on you just needed to add a variable with a true wired to it.
Have fun with it.

Tabbed selection screen with AT SELECTION-SCREEN ON events does not work

I have a selection screen with 3 tabs fields on each tab have AT SELECTION-SCREEN ON field events.
If you are on tab 1 and select a variant that populates fields on all tabs and then click the execute button ABAP does not seem to recognize that the field has changed when it executes AT SELECTION-SCREEN ON field event unless you physically go to each tab.
I can work around this by:
1) moving all of the AT SELECTION-SCREEN ON field events in a AT SELECTION-SCREEN OUTPUT event. This is not efficient and it potentially opens me up to other problems.
2) changing the selection screen to remove the tabs and have all of the fields on 1 screen. This makes for a very long screen.
Is there any way to have ABAP check all tabs?
Thanks,
Jerry

I finally got it to start. Let it sit and tried and it wouldn't but then I tried again and it did. How do I blow the dust out? I think it must be something with the heat since that comes up alot.

Issue with events not propagating when selecting toolbar items

Hey All,
I'm on OS X Lion using CS6 beta and observing events in Photoshop form an outside application using Cocoa's NSEvent#addGlobalMonitorForEventsMatchingMask.
It seems Photoshop is stoping the propogation of some events coming out of selection of toolbar items. Here's the issue:
There are two ways to select the Pencil tool from the toolbar. (Method A) I can click the Paintbrush, holding down for a second and releasing, then mouse move to the Pencil and click, OR (Method B) I can mouse down the on the Paintbrush and drag the mouse to the Pencil.
If I use Method A I get what seems to be every event associated with the interaction, BUT If I use Method B Photoshop seems to stop the propogation of a lot of drag events.
Are there any experts out there that have an knowledge of why this is, or if there are any known work arounds?
Regards,
Ned
ps This is also an isue in Photoshop 5

Ned, this is a bit over my head, but FYI (and your troubleshooting research), there are other methods to get alternate tools: ALT+click to cycle them, CMD/right-click to get the flyout, and Shift+Tool shortcut (unless you changed the setting in preferences)
BTW, method B is not the same as A? The only difference is that in A, there is a release, then a move to target area, then another click, while in B, we have a hold, then a move to the target area, then release.

Selected state issue with Menu Module V2

OK so I am getting an issue with Menu Module V2. I have used this before with success but this time I have hit a wall. I possed this question to BC live chat and they bugged out real quick.
The site in construction is http://www.urbanista.com.au
What is happening is that in the top right tools nav with the headings Home, Services, People, Contact Us using Menu Module V2. The Heading Services has a drop down and this is where the issue resides. Roll over any of these nav devices and you will see they will highlight orange. Home is already auto activating its Selcted state. Click on Contact Us and it will do the same. Roll over and click on Services and it appears to have worked. While in Services roll over the drop down again and you will see all links have activated the Selected state. This is the issue. If you view the code of the Services UL you will see only the Services state has been alocated the Slected state. See below:
<li id="Services" class="selected">
<a href="/services.htm">Services</a>
<ul>
<li id="tools-panningdev">
<li id="tools-housing">
<li id="tools-urban-renewal">
<li id="tools-project-management">
<li id="tools-feasibility-tools">
<li id="tools-governance-systems">
<li id="tools-communications">
<li id="tools-projects">
</ul>
</li>
The CSS that runs the nav is as follows:
ul.dropdown {
    font-weight: normal;
    font-family: Arial, Helvetica, sans-serif;
    font-style: normal;
    text-decoration: none;
    ul.dropdown li {
    background-color: transparent;
    color: #999;
    padding-top: 5px;
    padding-right: 10px;
    padding-bottom: 5px;
    padding-left: 10px;
    font-size: 12px;
    ul.dropdown li.hover,
    ul.dropdown li:hover {
    background-color: transparent;
    color: #FFF;
    ul.dropdown a:link,
    ul.dropdown a:visited    {
    color: #FFF;
    text-decoration: none;
    ul.dropdown a:hover        { color: #ff871f; }
    ul.dropdown a:active    {
    color: #b33b00;
    /* -- level mark -- */
    ul.dropdown ul {
    width: 150px;
    margin-top: 1px;
    background-image: url(/images/nav-transparency.png);
    background-repeat: repeat;
    color: #FFF;
    ul.dropdown ul li {
    font-weight: normal;
ul.dropdown li.selected a {
    color: #ff871f;
The last entry 'ul.dropdown li.selected a {color: #ff871f;}' is required in order to allocate a Slected State. Without it not Selected state is active and the links al remian white.
I have tried all manner of combinations and additonal tags with no success. Any suggestions greatly appreciated. I have not modified the default Javascript provided by BC in the system apart from allocating the required ulTagClass as specified. The Javascript in the supplied 'container.html' is as follows:
<script type="text/javascript" >
    // ids need to be unique per page, use different ones if you are including multiple menus in the same page
    // id of the nav tag, used above
    var divTagId = "myMenu1";
    // desired id for 1st <ul> tag
    var ulTagId = "myMenu1List";
    // desired class for 1st <ul> tag
    var ulTagClass = "dropdown dropdown-vertical";
    if ((null !== ulTagId) && ("" !== ulTagId)) {
        document.getElementById(divTagId).getElementsByTagName("ul")[0].setAttribute("id",ulTagId );
    if ((null !== ulTagClass) && ("" !== ulTagClass)) {
        document.getElementById(divTagId).getElementsByTagName("ul")[0].className = ulTagClass;
    // this will set the selected state
    if ((null !== ulTagId) && ("" !== ulTagId)) {
        catSetSelectedCSSItem(ulTagId);
</script>
Lastly this is one of the recomended navs by BC at the following address: http://lwis.net/free-css-drop-down-menu/
I have used these before with success but for the life of me this has stumped me big time.

Hi Matthew,
Having a super quick look at the code I'd say it's because of:
ul.dropdown li.selected a {
    color: #ff871f;
This affects all the child elements.
To override this down the line you could do something like:
ul.dropdown li.selected ul li a {
    color: #fff;
This would override the parent link color when selected.
You could probably then also add:
ul.dropdown li.selected ul li.selected a {
    color: #ff871f;
For the dropdown selected states.
That's a quick look though so don't quote me too much

Menu selection event

Is there any way to generate a Menu Selection Event for a menu item that has a sub-menu?

You can handle the "Menu Activation?" (Filter) event to set the menu item info before it is displayed.
The attached VI has a custom menu. Set the "Checked?" boolean to the desired value and then activate the menu to see the effect.

Menu selection with timer callbacks

Hello,
I am using LabWindows 5.0.1 to display event logging data at regular intervals
based on a timer callback (200 msec). The data is displayed on the main
panel in listbox controls, etc.
When timer events are enabled, I'm having trouble making menu selections
from the panel menu. When I click on a menu bar entry, I get the drop-down
menu list, but it disappears before I can make my selection.
How do I solve this problem?
-Thanks

I can't select Photoshop CC 2014 when using the "Open with" menu in Windows 7

I have recently installed CC 2014, and uninstalled my CC version. When I go to a jpeg, or any image file in windows explorer, I right-click and "open with" and it isn't listed on my program list to open the file with. I click on "browse programs", find the exe file in adobe-photoshop cc2014 folder and click OK, and it just goes back to the open with menu with no option for photoshop.
Any ideas on how I can get it on that list, so I can open these files from the file location, instead of opening up photoshop and then searching for the file location within photoshop?
Also, I don't have any problems opening up the pictures from within photoshop, just within windows explorer.

I'm having a similar problem, but only with jpg's. I have PS CS6, CC, and CC 2014. Other image file formats function normally with regard to the "open with" list. PS CC 2014 appears on the list. But with jpg's only PS CC appears on the "open with" list and 2014 can't be added by the browsing for it.
The curious thing is that if I have any of the three versions of Photoshop open, click on Photoshop CC in the "open with" list, the image opens in whatever version is already open on my computer. This is true of all image formats. No matter which version I pick from the "open with" list it opens in the currently running program. I use only the latest version so keeping it open all the time is an easy work around. I won't uninstall any of the earlier versions lest more file association quirks result. it would be nice to have this matter fixed.

Conditonal formatting with expiration date dependant on dropdown menu selection

Hello all,
I've got an interesting one for you.
I'm creating a report tracking excel spreadsheet. I have to suspense the return of the report. That being said I want to find a way that I can have the row turn red if the suspense date is past but only if the another cell does not have a specific selection
from a drop down menu selected.
Specifics:
J2 starts the column for the suspense date. G2 Starts the Drop down list. If the G2 (drop down) has anything selected other than "Complete" The row should be red. Once "Compete" is selected the rule should now longer be employed.

Thanks for the quick reply George. Sorry for the confusion. Suspense is the military term we use. Basically, I send a report to someone and they are required to get it back to me by the suspense date (or due date). Its just the date in which they are required
to send the report back to me. Until it is returned, the report is still "in suspense." That is why once the "Complete" is selected in G2 form the drop down list, I woul dlike the rule to no longer be applied. Does that answer/clarify your
question?
Thanks again Jeremy

Best practice for responding to keyDown event

I am writing my first Cocoa application. It's a simple utility app -- a calculator. I've got everything working, the last thing I want to add is I want the app to respond to key press events. So, you could click the "4" button with the mouse, or you could just press the "4" key on the keyboard. I'm reading all the event handling documentation, but I'm not picking up on the recommended approach for getting an NSResponder (or NSView) that handles the event.
I can make a subclass of NSWindow and tell the interface builder to make the main window of that type. Then when I override the keyDown message in my new NSWindow subclass, it gets the events, but I'm not sure how to connect it to my application delegate class (since I basically just want to switch on the key pressed and call the corresponding message in the delegate that the button "select" action targets.
Or, I think I heard something about doing this by changing the super class of the application delegate class from NSObject to NSView, or NSResponder or something. I haven't poked at that idea much, but I'm not sure how to actually get the application delegate object then actually set up as the first responder (I think that's what I'd want to do).
So, I'm hoping someone can give me specific directions on how/where I should implement my keyDown method, but I'd also like to understand what the recommended "best practice" is for doing this. What would Apple say is the right architecture for doing this? I'm as much interested in learning how to make this work as learning the Apple design pattern behind it.
The structure of my program is as follows:
I have one nib file (actualy a .xib) where I've designed my window with a textbox for display and a hand-ful of buttons. I've registered outlets and actions from there to the AppDelegate class (the one that the standard project template sets up for you). Following the MVC pattern, I then have a Calculator class that the AppDelegate initializes and all the actual logic of the calculator is in that class. The AppDelegate basically just responds to messages from the buttons, passes them along to methods in the Calculator class, and then asks the Calculator for the current display value and updates that back into the textbox. So, the graphical elements in my nib file are the "view", the AppDelegate is the "controler" and the Calculator class is the "model". Right?
So, who is supposed to be handling keyDown events? Seems like the view should capture them and send them to the controller, but how do I set that up?

Dear Noppong,
You can do it with multiple ways like :-
1. Get the current host name and make complete URL with using host name for the webdynpro iview.
request = (IPortalComponentRequest) this.getRequest();
HttpServletRequest req = request.getServletRequest();
StringBuffer strURL = req.getRequestURL();
