Warning when casting object into generic type at run time.

I am getting this message when casting an object at run time:
Type safety: The cast from Object to Tree<V> is actually checking against the erased type TreeI'm overloading an equals(Object o) method in my class.
Is there a way to get rid of the warning (besides turning the warning off :))

I'm overloading an equals(Object o) method in my
class.
Is there a way to get rid of the warning (besides
turning the warning off :))No. The best you can do is what is demonstrated in the previous link.

Question about casting objects into Number

This might sound a bit silly, but i have a function that
casts an Object into a Number and then checks if it is NaN to
ensure that it is indeed a number, it returns true if it is a valid
number or false if it isn't a number
Now i have a TextInput and when i type for example "HELLO"
and call the function it returns false (since that is not a
number), if i type 23 it returns true (it is a number), if i type
"20a" it returns false. Everything works fine except for one
combination, if i type any number and the letter "e", for example
2e, 9E, 5e, etc, it returns true, which means this is a valid
Number, why is this?

I thought it might be that, but for my bussiness logic, 2e is
not a valid number.......will i need to parse the string and
validate it?

Casting Object into primitive

I'm using java reflection to return value of an attribute from a Class. The attribute is a float primitive. However, the return form is an Object. How do I cast it into the float primitive again?
Thanks.
LG

From the API for Method.invoke: >>if the value has a primitive type, it is first appropriately wrapped in an object<<
So if the method returns a float primitive, Method.invoke will return a Float object.

How to determine itab type at run time

I need to write a subroutine that organizes data in internal tables for presentation by a smartform. There are a few similarly structured internal tables all with the same field name ("recipe_type") by which the data is sorted. My problem is that how I can determine the type of the itab inside my subroutine at run time? Is it ever possible in ABAP?
The subroutine code is attached below. Thanks for any help.

The following code does what I want, but only if the input itab structure is declared first in the program. It won't work if the itab is declared as itab_in TYPE TABLE OF sflight. This is because the function 'GET_COMPONENTS_LIST' only can load the structure of a field declared explicitly in the program. Does anybody know of any method to load the structure of an itab based off a dtab?
Thanks you guys for answers. Points have been rewarded.

Error 1003 when loading a VI dynamically on LabView Run-time ini file configuration

hi all,
I have a problem with my runtime excutable.
On 4 systems, all running XP it runs fine.
On 2 systems ( one a new install of just LVRT 2011 SP1 ) I have:
Error 1003 when loading a VI dynamically on LabView Real-time
Or more spoecifically the error code is 1003 and the error source is Open VI Reference.
When the RT app runs correctly I get these paths:
Path Sent to Open Vi Reference: Yeast_Grower.exe\Tecan_talk_Control.vi,
Path Returned from Open Vi Refence: C:\Program Files\Yeast_Grower\Yeast_Grower.exe\Tecan_talk_Control.vi,
On a system that does gets the 1003 Open Vi Refence error I have the same Path Sent but of course no path returned as it does not open.
To be sure that the vi Dyanmically called vi is compiled and valid at runtime I also include a copy of in the main.vi.
To be extra sure I have also installed the runtime versions of VISA and DAQmx.
I have compiled it with and without the "Use LV 8 calling hiaracy"
My conclusion as this stage is that either the installation of LVRT 2011SP1 misses something the earlier LVRT installtions make.
or is there a MyApp.ini or LVRT .ini that controls how the RT dyanim calls are handled.
Help very welcome how to solve this puzzle.
thanks
michael

I understand that all the PCs (6 of them) have LV 2011 SP1, runtime or the development system installed. Right?
How many of these PCs have the source code available on them?
-> Only one of them has the source code.
I am not sure I understood 'I also include a copy of in the main.vi'. Does it mean you placed the subvi in the main.vi?
-> I meant I have included in main.vi the actual vi that is called dynamically - but only where it is not called.
Did you try including the sub vi which is called dynamically, as 'Always included' in the EXE build?
-> No, I did not know of this option - but the above I did this by default.
Edit: Did you verify the software versions of LV RT, VISA etc on all the PCs? Are they same?
-> I did verify even added DAQmx just in case
There is lots of material available on this forum for error 1003 and dynamic vi calling. Did you find anything useful to try among the forums threads?
-> I did view many of them.
I did finally find the answer.
I have a subvi (callNet.vi ) in the dynamically called vi (dynamic ) that calls .Net libraries.
Now the thing is that this subvi callNet.vi is coded out by enclosing it in a Disable structure.
In fact this subvi ( callNet.vi) does not even compile - ie it has a broken arrow
however if enclosed in a Disabled structure and disabled, the enclosing vi compiles OK.
However I have discovered that even with the .Net calling subvi (callNet.vi) in the Disabled state of the Disabled structure
the enclosing vi (dynamic.vi ) does NOT run - although it compiles just fine.
Once I installed the .Net libraries (I actually did include them with my app installer ) with the vender's supplied installer
then my app now successfully calls the dynamic vi.
So the Summary and warning is: Even if the dynamic called vi is included in Main.vi and Main.exe runs ( but does not call the dynamic vi - except when called dynamically at later some point ) and even if, in this case, the .Net calling subvi is disabled out ie no .Net calls are made the dynamically called vi will not run when called dynamically.
I hope that is not too confusing. In summary it seems the Disable structure does not entirely disable.

to samb,
It doesn't look like you are getting a runtime error. Is it possible your query is returning no rows?
If you are sure your query should be returning rows, you probably need to check if DBMS_OUTPUT is enabled in SQL Developer (View menu I think).my query is returning a row
where where 123=key and 'FUBAR'=gradename?
If so, you want 3 single-quotes at the end of the string, not 4:
You sure? I think 4 is correct.i am sure 4 is correct i have tried as per jeenesh said

Read Data's from the Form step type at run time

Hi Experts,
I have the 'Form' step type in my workflow and it will displays some values at the Run time. In this form I have one IO field called 'Comments'. So at the runtime manager can Enter the comments on it.
Now my need is I need to get the 'Comments' data from that form. How can I get this value?
Thanks in Advance,
Helps will be Appreciated..

I got the solution.
Thanks All..

When access BW from Crystal I get: run-time error '-2147417848(80010108)'

Installed Crystal and the SAP int Kit in the correct order. I can access R/3 but get an error when trying to access BW:
run-time error '-2147417848(80010108)'
Then Crystal crashes and shuts down.

Yep, I have the same... The only one solution for me for now is open report, then log in to BW using toolbar icon from SAP integration kit bar. Only after that you can work with this report without crash.

Can you safely cast Object to generic Set MyType ?

I have a property change event evt where evt.getNewValue() contains a Set<MyType> value and I want to do the following:
Set<MyType> newSet = (Set<MyType>)evt.getNewValue();
Is there a "safer" way of doing this which satisfies the compiler enough to prevent the unchecked warning?
Before going any further and replying with something like MyType<T> is lost at runtime, I want to add that I can do:
MyObject<MyType> myObj = new MyObject<MyType>();
as well as:
MyObject<MyType> myObj = createMyObj(MyType.class);
{.. and somewhere alternatively: return clazz.cast(o); }
So why can't I do something similar with Set<MyType> such as:
Set<MyType> newSet = Set<MyType>.class.cast(evt.getNewValue()); // compile error obviously.
I suppose I'll just have to go with:
Set newSet = (Set)evt.getNewValue();
for (Object o : newSet)
MyType myType = MyType.class.cast(o);
}

This would only be helpful, if one also changes the PropertyChangeListener interface topublic interface PropertyChangeListener<T> {
void propertyChange(PropertyChangeEvent<T> evt);
}making it parametrized by the Type of values so the listener can receive type-safe events. If you don't, you will have the same problem as the OP with casting to the parametrized event type.
Same, if one only uses a wildcard for the parameter's type.
Of course, doing so is possible for your own classes, if you do not have to be compatible with any Swing or AWT code. One would have to implement specific listeners for each type of evented value, though, as it is not possible to implement the same interface more than once having different parameterizations. It seems by far more overhead and complex than simply checking and casting the value received by the event.

Unable to load LabVIEW VI into TestStand using LV Run Time only

I'm unable to load some of my VIs into TestStand from LabVIEW. I am using:
TestStand 4.2.1
LabVIEW 2010
I have the appropriate patches installed for both TestStand and LabVIEW, and I still get the error.
Attached is a message that I get when I hover over the "!" to explain my error. The VI has the "Simple Error Handler.vi" as part of the build, and when I eliminate this VI from my VI, TestStand then loads correctly.
Thanks,
Eric

This fixed my issue as well. Thank you for posting this. I have repaired LabVIEW 2010 sp1, LabVIEW FPGA, LabVIEW RT, DAQmx, and VISA 5.0. These are not small programs to do repairs on. Even after doing all of these repairs I still had issues with just labview coming up.
Just by clicking on my lv shortcut to run the labview.exe I would get a loading screen for gws_int.vi This was before opening any projects or VI's. Labview was having many issues. Once the loading vi screen went away the standard labview 2010 startup page was present. But this page was dysfunctional. For example if you clicked tools and then options it would just totally crash LabVIEW, no error message or warning.
Many people are suggesting to mass compile to fix this, but that is not an option. If you went to tools>advance>mass compile the same loading vi screen would come up (pic A), but then the mass compile program would have a broken arrow (pic b) I included a image to show people this.
The error list will always pop up, but there are no errors.
I called NI tech support and they suggested that I repair all of my programs starting with the largest programs first. During the repairs I found this forum. I have over 30 different NI modules installed on this machine, I would have been at this for the next two days.
Thank you very much for this.
A good question is why didn't the repairs of these large programs find this, and would any repair of any module have fixed this?

How to drag and drop a object in an indicator at run time?

How to drag and drop a picture at run time in a indicator displaying pictures on the front panel. The main thing is that the window is displaying frames continuously?

Hi Vivman,
You have duplicated this post here. Please do not post the same question to separate forum post.

Pasting multiple objects into frame

Greetings everyone
I was wondering if someone could shed some light on how to best paste multiple objects into a single frame.
Mainly, I'm trying to nest objects that form a part of a newspaper article header; since it's a design element that keeps repeating with each single article I don't want to spend time with manually positioning the elements each time--it's time consuming and prone to sloppiness.
Unfortunately, the base frame will have about three objects that need to be nested within it. Once I paste one object into a frame, the next time I do `Paste into`--the content (previously pasted object in this case) just gets overridden.
I've read that, to paste multiple objects into a single frame, one should group the objects first. Now this works pretty well for getting them into the frame, but leaves me with no options to position them relative to the frame. I can't move or position an object individually and I have no option to ungroup them once they've been pasted.
Here's a small mock-up to depict my peculiar predicament:
Ideally, I'm aiming to have the main header frame to fit the content of the nested objects and for it to be flexible enough that I can quickly span it across multiple columns as per article requirements.

!kRON wrote:
For items that are part of the group, their (X,Y) location coordinates are relative to the document--neither to the group nor the parent frame. The group itself has coordinates that are relative to the parent frame (X+ offset, Y+ offset). I can select the group and the parent frame and use the align to selection options. For individual items, I cannot make a selection of both them and the frame, only between items that are part of a group. I loose options to align an individual item relative to the parent frame, which means I have to drag them around and rely on smart guides.
I've tinkered around some more and it'd appear it's not possible to lay out the elements as I imagined. So I have to resort to grouping the items that would form a frame and pasting them into a frame. If multiple frames have to be members of a single frame I'd have to group the frames and paste them into the single frame and so on.
Based on my layout mock-up, I'd end up with 3 frames within the header frame:
Article header
Heading
Article type
Separator
Article heading
Title
Footer
Author
Shape
Based on experience, should I go with this or stick with the old fashined moving around of loose elements? Will it be a lot of work to maintain resizing and repositioning of the various items and their frames once I start changing the width and height of the header frame or will it save me some time?
I'm not a working designer or production worker, so anything new takes me longer than I think it should, because I don't have a rich reservoir of quick methods at my fingertips.
Your description above interested me, because I've been wrestling with the annoying limitations of manipulating and adding compound objects in anchored frames. For many situations, it's probably simplest to assemble each iteration of a compound object, that introduces a new element, outside the anchored frame, then group the elements and paste the grouped object into the anchored frame.
However, the arrangement of elements in your example made me think that a table might be a workable solution. The answer I arrived at is "Yes, it's a solution, but it takes a while to set up." If it's reusable easily, then it might be worthwhile investing in a few experiments.
I've attached a zipped idml interchange version of the file, and also a PDF.
Here are some notes:
* I created a table with three rows and three columns, no header or footer rows. Three columns because I thought I'd paste a vertical line into an inline anchored frame in the center cell of the top row, for the separator line. Later, I realized that defining the vertical cell rule as paper color would suffice, so I merged the two right cells on the top row to create a two-column row, with text in each cell and the vertical separator between them.
* I merged all three cells on the second row into a single cell.
* I merged the two right cells on the bottom row, but later, when I moved the cell rule to position the triangular graphic in the inline anchored frame in the right cell, it moved the vertical cell rule in the first row. So, I had to unmerge (or split) the cells, and cut/paste the triangular graphic's anchored frame into the rightmost cell. To position the anchored frame, I moved the vertical cell rule with Shift+Drag, to keep the table width unchanged.
* I sampled the purple color with the eyedropper tool while cells were selected and the swatch panel was set to fill the selected object.
* I didn't spend much time matching the type, as you can see. To position the text, I adjusted the cell margins in some cases, and left/right indention in some cases; I'm not sure which is more efficient in situations where there will be different amounts of text to fit. I didn't create cell styles or paragraph styles (BAH! Bad, bad, bad process) because I won't be repeating this stuff, but you probably will benefit greatly from defining styles for your repeating needs.
* The triangular cut into the bottom row made it easy to manage creating and positioning the graphic. A non-geometrical object might be trickier. The triangle is a text frame, set to negative space above, so it overlaps the cell above it, enough to avoid a black gap.
* Except for the vertical paper-colored divider line, all the cells have zero-width strokes.
* I created the table in a text frame, that I fitted down to the size of the table, but I can't remember if I selected, copied, and pasted the text frame into the text flow to anchor it, or if I selected the table in the text frame, copied and pasted it into the flow. Not sure if it makes a difference in work efficiency.
If I understand your general needs, this should work well for changing text and adjusting the column widths.
