How to do a taskflow call without pushing an entry on the page flow stack

Hi,
I have a use case where I have to do a task flow call with parameters as the final state of my task flow. That is, I don't want he called task flow to ever return a value so I don't need the called task flow to be stacked over the calling one, just replace it and close the calling task flow.
Normally, I think the good way to do that is to use an URL view activity, but in my specific case, some of the taskflow's input parameters have to be passed by reference so encoding them in a stateless way within an URL is not very exciting as it would imply pushing an id of the object that would need to be stored in the request or another shared area.
Is there any good practice or some other method I'm not aware of to achieve this?
Thanks,
~ Simon

Hi Simon!
If I understand you in a right way, the way to achieve this is to wrap both taskflows (calling and called as you refer them) in one external taskflow. This way, the your "calling" taskflow should return to wrapper all params you need to pass to "called" (and then you call "called" from wrapper by passing these params you got on return from "caller"). That way, the "called" is not stacked over the "calling".
Of course, you still have both "calling" and "caller" stacked over wrapper, but that is a cost of current subroutine-style taskflow invocation mechanism provided. Basically, there is no "Go To" in taskflows (beside Url calls but without params passing – well, that is a true "Go To").
On second thought, I'm not 100% sure but you may investigate datacontrols sharing options. If both "calling" and "called" share datacontrols with wrapper, then the stacking overhead of wrapping is negligible and you almost have your use-case.

How can I print a booklet without a white outline around the border?

How can I print a booklet without a white outline around the border? I'd like the front page to be covered entirely.

You either need a borderless printer, or you have to print on oversize paper and trim off the bleed.

How can I resize an image without losing resolution or using the crop tool? I am using Photoshop Elements 13 on a PC.

Hi Peru Bob,
I've tried two images, the results were:
Image 1
Jpg, original file size 923KB, dimensions 848px x 279px.
After resizing to 848px x 180px with 72dpi, the file size decreased to 164KB.
Image 2
Jpg, original file size 809KB, dimensions 1200px x 1800px.
After resizing to 668px x 722px with 72dpi, the file size decreased to 307KB.
So, there seems to be a fair file size loss - is this to be expected?

How come 64 GB storage can hold only 100 entries in the call list. can anybody explain the reason?

Because the "Recents" is limited to exactly 100 calls, by design...nothing to do with the size of your phone. Tell Apple if you liked to see it increased:

How to tell whether one driver(say driver A) is in the same driver stack with another driver(say driver B)?

I'm new to WDF, so the questions below might be trial. However, I cannot find the answers in MSDN or text book(e.g. Developing Drivers with the Microsoft Windows Driver Foundation)
The questions below only apply to KMDF on Windows Phone.
1. Can I say that one *.sys file is one driver?
2. How to tell whether one driver(say driver A) is in the same driver stack with another driver(say driver B)?
3. If several *.sys files are included in one *.inf file, can I say that those drivers are in the same driver stack?

Drivers are not in a stack, the devices created from the driver are. Consider having two identical pieces of hardware in a single computer, each will have a device object which will come from the same driver, but each device object will be in
its own stack. Things can get even more complex since a filter driver can create more than one device object in a single stack.
Just as a single driver can create devices that are in different stacks, your question on multiple drivers in an INF has the same answer, there is nothing that says they will be in the same stack.

How do i have subsequent fields label and values move down the page dynamic

how do i have subsequent fields label and values move down the page dynamicly...
the field in question "can grow" and can become quite big...overlaping the content of the fileds below...how can i make the fields below this large field move dyanmically so there is no overlap?

if it is the same field and it is set to can grow you just need to make sure you put space between by inserting a section below

How do you create an array without using a shell on the FP?

I want to be able to read the status of front panel controls (value, control box selection, etc.) and save it to a file, as a "configuration" file -- then be able to load it and have all the controls set to the same states as were saved in the file. I was thinking an array would be a way to do this, as I have done that in VB. (Saving it as a text file, then reading lines back into the array when the file is read and point the control(s) values/states to the corresponding array element.
So how do I create an array of X dimensions without using a shell on the front panel? Or can someone suggest a better way to accomplish what I am after? (Datalogging doesn't allow for saving the status by a filename, so I
do not want to go that route.)

Thanks so much m3nth! This definitely looks like what I was wanting... just not really knowing how to get there.
I'm not sure I follow all the icons. Is that an array (top left with 0 constant) in the top example? And if so, that gets back to part of my original question of how to create an array without using a shell on the FP. Do I follow your diagram correctly?
If I seem a tad green... well I am.
I hope you understand the LabVIEW environment and icons are still very new to me.
Also, I had a response from an NI app. engineer about this problem. He sent me a couple of VI's that he threw together approaching this by using Keys. (I still think you are pointing to the best solution.) I assume he wouldn't mind m
e posting his reply and the VI's for the sake of a good, thorough, Roundtable discussion. So here are his comments with VI's attached:
"I was implementing this exact functionality this morning for an application I'm working on. I only have five controls I want to save, but they are all of different data types. I simply wrote a key for each control, and read back that key on initialization. I simply passed in property node values to the save VI at the end, and passed the values out to property nodes at
the beginning. I've attached my initialize and save VI's for you to view. If you have so many controls that this would not be feasible, you may want to look into clustering the controls and saving the cluster as a datalog file.

iTunes purchases cannot be transferred between accounts. If you no longer wish to use the old account at all, you should delete those apps and repurchase them with the new account.

How can I export a Video without making it darker than the original file?

Hi there!
I'm working on a footage shot with the Canon 5D and since the first step in the post I exported the raw footage with Apple ProRes 422 (HQ) and worked with it in After Effects and later on FCP and then the usual Color and Compressor. But somehow every time I exported it, it got darker and darker... I tried using Animation codec instead of Apple ProRes 422 (HQ) and it didn't get dark but the files are HUGE and in the end I have to export the video in H.264 for internet. Does anybody out there have any idea what should I do and which compression should I use and how?
Thanks a lot!
Davi

When you say you exported the raw footage... are you working with native H.264s in FCP?

How to delete paragraph marks (returns) without affecting spacing, like at the top of the next page

if you have a large document and you add two returns at the end of every major section or group but one of the two returns goes to next page, how do you keep that return so it doesn't mess up spacing if something is added earlier in document but get rid
of it so the top of the page is the same as the other pages? I was wondering if there was something like a hidden return that would hide the paragraph at the top of the page but if more information was added before it, it would act like a regular return. Hope
this makes sense.
Also do you know what the paragraph maker with a dotted box around it is? I was trying to solve the above problem by trying different keys with the return key, e.g. control + return gives you a page break, shift + return gives you a soft return,
control + alt + return gives you this funky paragraph symbol that seems to erase lines in front of it at least it did when I printed out a page using them.

Thank you! I've never used Styles but have used the formatting. I just didn't want to have to go to the bottom of every page and change the paragraph formatting but format painter helped a lot. Thanks again.
You could also use a heading style for the start of your next major block of text which is formatted to have a page break before. Styles are at the heart of Word formatting. Take the time to learn about them to save a lot of time and hair pulling.

link that Stefan gave you. If you want more, see

Sorry I cannot help with this utility. What is your database version? In 10.1 and later, the recommended way is using JPublisher. Download JPublisher 10.2 and the webservice callout utility.

How to change the "Page Flow Error - Unsatisfied Role Restriction" page

When you try to access a page and are denied authorization to it, Weblogic automatically redirects you to a
"Page Flow Error - Unsatisfied Role Restriction" page, on the bottom of which tells you what roles you have to be in in order to access the resource. My question is how can I change this page to match the general look and feel of my application?

I know you asked this almost a month ago, so you may have already figured it out... but you just need to add a handler for com.bea.wlw.netui.pageflow.UnfulfilledRolesException. Something like this:
@jpf:catch type="com.bea.wlw.netui.pageflow.UnfulfilledRolesException" path="roles-error.jsp"
You can put it at the class level of a specific page flow, or at the class level of WEB-INF/src/Global.app, which will apply it to all page flows.
Hope this helps.
