Question about stacked canvas disappearing
Hi,
I have a block which has some database items and non-database items. Since
there are many items in the block, I use a stacked canvas with horizontal bar
to display the less important items.
In the trigger of new-block-instance, show_view('stacked_canvas')
But I face one problem. When I click on a non-database item and then move
the cursor away from the item, the stacked canvas suddenly disappears.
Any idea ?
Many thanks in advance
Imagine each canvas as a piece of paper stacked on a desk. Each piece of paper possibly has a different size and the top left corner of each piece is possible oriented in a different spot. When you say show_view('stacked_canvas') its like reaching to the bottom of the pile and putting that canvas top. When you click on an item not on the stacked canvas that items canvas is placed on top. Your problem is that your non-database item content canvas is covering up the stacked canvas. I think...
Your issue could be solved by simply rearranging the canvas order by putting the stacked canvas last (I think) in the object navigator.
Raise on Entry could also be causing your issue. Go to the help. Click the search tab. Type "raise on entry". Read "Working with the Raise on Entry Canvas Property". There is a good explanation in there on how stacked canvases get covered up by content canvases and when.

Hello Everyone,
I have a quick question about stackwise plus technology. I would like to confirm that there is no redundancy at the ethernet switch port in terms of a physical problem. The reason I ask is that we are deploying stacked switches shortly to ensure high availability but curious to know whether anyone has seen issues with physical ports failing and not the chassis/PSUs. I understand that Etherchannels can be used but we have security cameras that cannot suffer any outages and would be connected to a single port on the stack. I'm guessing that my option is to monitor the Switch Ports statistics via SNMP and move the camera to another port if this ever happens.
Thanks in advance.
Cheers.

Sure, ports can fail without the whole switch failing, but edge redundancy, such as using dual links (often configured as a bundled channel), between the host and two stack members addresses both switch port failure and stack member failure.
Unless your security cameras support dual links, your going to have a single point of failure at the edge port.
Next best options, as you've already noted, would be to have, on-line, "warm" spare ports that you can quickly repatch into. Ideally you have enough spare ports to allowing repatching in case a whole switch member fails.
(BTW, when you have spare ports, you don't have to set aside a whole stack member, sitting empty. For example, instead of having a dual stack with only one switch member populated, and the other not at all, split the populated ports across both stack members. That way, if a stack member fails, you don't lose all your hosts, only half. [With cameras, depending on their views, you might be able to overlap their coverage across multiple stack member.]) -
Question about stacked graph from DB
Hi There.
Ive come up against an interesting issue in my current project. In my prototype I have a stacked column chart (just one column) with the 'sections' of each column being defined as in the Flex docs, i.e. I have 3 column series I will call col1, col2, and col3. This works great but now my problem is that when I start getting data from the DB, I could have any number of column series as I have in the DB data pairs in the form of; col1 - 23, col2 - 34, col3 - 14... And there can be x number of records. Has anyone got any references or ideas about how to go about this?
Thanks in advance.Getting on with this I can say I have made (some) progress.
The file looks as follows:
<mx:ColumnChart id="columnChart" type="stacked" dataProvider="{this.chartData}" width="507" height="100%" x="781" y="0">
<mx:horizontalAxis>
<mx:CategoryAxis categoryField="category" dataProvider="{this.chartData}"/>
</mx:horizontalAxis>
</mx:ColumnChart>
And the AS part:
private function createChartSeries(event:ResultEvent):void
var temp:ArrayCollection = event.result as ArrayCollection;
chartData = new ArrayCollection();
var i:int;
chartData.addItem({name:"val1"});
chartData.addItem({name:"val2"});
for (i = 0; i < temp.length; i++)
var series:ColumnSeries = new ColumnSeries();
series.xField = "name";
series.yField = temp[i].call_type.toString();
series.displayName = temp[i].call_type.toString();
chartData.getItemAt(0)[temp[i].call_type.toString()] = temp[i].cost;
chartData.getItemAt(1)[temp[i].call_type.toString()] = temp[i].duration;
columnChart.series.push( series );
columnChart.dataProvider = chartData;
columnChart.invalidateSeriesStyles();
columnChart.series = columnChart.series;
[Bindable]
public var chartData:ArrayCollection;
The event.result is as follows:
[{type:"t1", val1=10, val2=30}, {type:"t2", val1=20, val2=3}]
Now call the "createChartSeries" function the y-axis updates, there are 2 columns (well the grey bit down the bottom), but there are no names (the x-axis values) and the actual data columns do not show up.
Can anyone help me with this one? -
Hi All,
Iam using forms 6i..its not working when Iam trying to call a canvas from a procedure but working if i write the code in a button (when-button-pressed)
Iam using go_block('abc'); ---say abc is the block name in that canvas..
If i use pause; after this go_block i can see the canvas. This canvas is having one text item and one button
Thanks in advance
Girish kotapatiThat sounds like a "Hack" to me. You shouldn't have to fail the form to make things work. What about the code that comes after the RAISE Form_Trigger_Failure? This code will never execute because you have halted execution. A better solution would be to trace through your form (either by turning runtime debug messages on or by using Forms Runtime Diagnostics [FRD]) to see why your form is not behaving as you are expecting.
Hope this helps,

i've been with aperture since 1.0 so forgive my ignorance on this. I vaguely remember pre 2 that with stack you could do a search (either keyword, star, or whatever) and it would list all the photos that match that and the one in stacks you could open the stack and view the ones that weren't part of the search.
Let me try to explain my problem, perhaps that will help with the understanding. I have a fairly large library, a bit over 50,000 photos. there are hundreds of folders and projects and everything is very nice and neat. I have keywords and ratings on most of the images in my library, but I'm running into an issue regarding images in stacks that are not keyword or rated.
as an example, let's say I have a stack that has five photos in it, each rated one through five, with five being the stack pick. The stack is collapsed and life goes on only later I do a search for say all the 3 star or greater photos. In that search there are times when I want to open up the stack and see the rest of the photos to, in case say I wanted to upgrade the rating on something I'd missed.
Case i point, I have a smart album right now that's looking for photos with a certain keyword. The album has 'about' 300 photos in it. I say about, because roughly half of those are stacks. My problem is I want to add the same keyword to all the photos in the stacks but I can't view the other photos in the stacks because they don't have that keyword.
I would really like to figure this out. Anyone have any suggestions or hints. Maybe I'm just missing the button or not seeing some setting that I'm supposed to clickThe notion of "stacks" only has meaning in the context of a project, IMO. It was originally part of the Ap design as a means to keep light-table work habits a part of Apple's digital workflow solution. I find it most useful during culling/selection, but not much beyond that point.
What you are attempting to do is very reasonable, but in my experience the only way to do this is to visit each respective project as you find candidates with your global rating search. It would be easier if Ap allowed a "reverse" lookup directly from a selected image....maybe in Ap3??
I know this is not an attractive option for you, so maybe others will have a better suggestion.
Good luck.
cheers,

Question about stacked objects using blend modes
Say there are three stacked objects. The two topmost have a blend mode.
In the area where all 3 intersect, the bottom object interacts with the transparency. Is there a way to limit how many levels the transparency affects? If you could limit it to two levels, then in the area where all three intersect the bottom object wouldn't participate in the blending. But in the areas where it overlaps only one of the topmost objects, it would participate.
I know this can be achieved by creating another object, or using the Pathfinder, I'd just like to know if there is a simpler method to use.The attached PDF explains this better. Page 1 - the yellow and magenta are multiplied on top. But the cyan in not participating in the area where all 3 overlap. But in the areas with only 2 levels, it does participate, so there are the green and blue overlaps.
Since the cyan is negated from the one area, the result is red – yellow and magenta multiplying
The problem is, the only way to get this is to punch a hole in the cyan. So when you move the yellow and magenta around, the red doesn't follow (see page 2)
It would be nice if the blend modes included some sort of level limit. Default would be unlimited, but you could change it to 2 or whatever number you want. In this case if the level was 2, no hole in the cyan would be required.
As far as I know Adobe has not added to transparency capabilities for a long time. You have the 16 bend modes, and opacities. And knock out group and isolate blending, which are good features. But maybe it's time to expand on this and add more points of control. -

Question about Stacked Chart ... is this possible?
This seems possible but I cannot get APEX to do it, wondering if someone has any ideas:
Say I have a table with multiple records with columns which contain a DATE, PERSON, TEAM ...
I am comparing number of records per team but trying to show in the STACK how each person contributed ...
Lets say there are 5 teams ...
I want to end up with a STACKED BAR chart which shows HOW MANY INSTANCES (count(*)) per TEAM ...
I want to end up with 5 BARs and each subdivided with the number of record instances which each PERSON in that team.
So at the end of the day, we can see how different people contributed to the overall total of a team and we can see how each team fared against one another ...
Thank you!
CYou would build a series per team and group on your date value with same aggregate.
Sample series using EMP and DEPT tables. seen here Chart Axis
Series 1
select null link, TRUNC(e.HIREDATE,q') label, count(*) acct
from "EMP" e natural join "DEPT" d
where d.dname = 'ACCOUNTING'
group by TRUNC(e.HIREDATE,q')
Series 2
select null link,TRUNC(e.HIREDATE,q') label, count(*) sales
from "EMP" e natural join "DEPT" d
where d.dname = 'SALES'
group by TRUNC(e.HIREDATE,q')
Series 3
select null link, TRUNC(e.HIREDATE,'q') label, count(*) research
from "EMP" e natural join "DEPT" d
where d.dname = 'RESEARCH'
group by TRUNC(e.HIREDATE,q')

Question about stacked sequence structure
Hi,
I made a numeric control outside a stacked sequence structure, and connect the control both to frame 1 and frame 2. In frame 2 there is a while loop structure. And now I start the labview program with the control A. Then, after frame 1 finished, frame 2 started, now I want to change the control to B and deliver B into frame 2. But the indicator in frame 2 shows that the control is still A. So I wonder how can I change the control and deliver it to the frame after the frame has started? Thank you!
NI Software : LabVIEW version 7.1
OS : Windows XP
Regards,
jackaudenDataflow dictates what you are seeing. The control does not get read once the sequence starts. This is as expected.
Some possible solutions:
Just don't use stacked sequence! I don't and never feel limited by this choice.
Create local variable of the control and read from it inside frame 2.
Do you REALLY need a stacked sequence? Why???

Help:A question about stack
Hi, I met a weird problem,
try {
Stack stack=new Stack();
stack.push(a);
stack.push(b); //a,b are Objects
while(stack.peek() instanceOf Objects)
stack.pop;
System.out.println("Done")
}catch(Exception e) {
System.out.println("Error");
It could be worked, however, I always got the error message, which is so weird.
Can anyboy tell me the reason? Thanks a lot!
IrisTry the following program:
import java.util.Stack;
public class StackTry
public static void main(String args[])
try
Stack stack=new Stack();
Integer a = new Integer(10), b = new Integer(11);
stack.push(a);
stack.push(b); //a,b are Objects
while(stack.peek() instanceof Object)
System.out.println(stack.pop());
System.out.println("Done");
}catch(Exception e)
e.printStackTrace();
System.out.println("Error");
}The problem is when u are doing stack.peek()
After all the elements in stack are poped, stack.peek() is done in the while loop which causes exception to occur. Hence the Error message.
Put a condition to check whether the stack is empty before peeking into the stack.
This should help, i guess.

Simple Problem with Stacked Canvas, I hope
Hello all,
I am become a bit frustrated with what I thought would be a simple form development solution. I am trying to create a form with a stacked canvas that will display about 20 fields that can be scrolled through. This is the detail
Total of 25 fields
5 Fields on the content canvas
20 Fields on the stacked canvas
I created the first canvas that originally contained all 25 fields. Then I created the stacked canvas and moved the appropriate fields to the stacked canvas. Using the forms builder editor, I positioned my stacked canvas as such so that it would not overlap the last field on the content canvas or visa versa. This is a form being developed for Oracle EBus. Whenever I run the form in the apps, the stacked canvas is not visible. It only becomes visible when the 1st field on the canvas has focus. When the stacked canvas becomes visible, it shows all of the items of the stacked canvas and not just the ones that I included in the viewpoint. Once I tab through the last field of the stacked canvas, it goes back to the first field on the content canvas and the stacked canvas disappears. At this point I am not doing anything complicated, but for whatever reason this just is NOT working. Any advice anyone can provide, I would very much appreciate it. This is VERY frustrating.
Thank you in advance.Step No. 1
Set the STACKED CANVAS's property VIEWPORT WIDTH AND VIEWPORT HEIGHT
This property determines what viewable width and height of the stacked canvas at runtime.
Set SHOW HORIZONTAL SCROLL BAR or SHOW VERTICAL SCROLL BAR or BOTH as YES so that you can scroll down to view all the items in the CANVAS.
Step NO.2
In your WHEN-NEW-FORM-INSTANCE trigger, write the code to make the canvas visible
SHOW_VIEW('stack_canvas_name'); -
Hi
I have a screen where part of the block is in a 'fixed' content canvas and part is in a stacked canvas which is scrollable. Initially, both canvases are displayed and I can scroll backwards and forwards in the stacked canvas. However, when I select one of the fields that is outside the stacked canvas the stacked canvas disappears. Is there anyway of pinning the stacked canvas so that it is visible all the time.
ThanksHi
What i understand when your naviagation is on contact canvas item then stack canvas disappear.
it is so simple just click on the border of stack canvas and drag the stack canvas away from the items of contant canvas. it may possible your stack canvas is over the any item of contant canvas

Stacked contents disappear when reach the end of the field
I have one content canvas and one stacked canvas, I have putting the show_view('canvas1') to show the stacked canvas in the when-new-form-instance. However, when I press enter on the first field in the content canvas, the stacked canvas disappear immediately and when the cursor jump from content canvas to stacked canvas the stacked canvas is shown. When I keep on press enter reach the end field of the stacked canvas and jump back to the content canvas, the stacked canvas is disappear again. And the cursor still keep on reside on the firs record / row without jumping to the next two of record. How do deal with this ?
I need to shown the stacked canvas even the cursor back to the first content canvas and also I want the record to be jump into next row / record once it reach the end of the column.
Thanks.
Limhi
try something like this.
GO_BOCK('BLOCK.ITEM_NAME');
HIDE_CANVAS('CANVAS_NAME');
SHOW_CANVAS('CANVAS_NAME');sarah -
Tab canvas disappear when the main stacked canvas reach the end of column
Hi all,
I have 3 canvas ( 1 main canvas, 1 stacked canvas ) and this link to 1 tab canvas. All these are in the same window.
Whenever using the keyboard to press enter navigate from column to column and when it reach the end of the main canvas which is about to jump to the stack canvas, the two canvas ( stacked & tab ) was hide by itself. Even I have stated earlier to show all canvas in the pre-block trigger. when I keep on press the enter to jump to the next stacked canvas, this stacked canvas is being shown again. My tab canvas was not appear if I am press the enter key. However, if I press the arrow key down the tab canvas is appear. This I wasn't do any code to call the tab canvas.
When I keep on press enter and reach the end of the stacked canvas again the tab canvas is disappear, unless I have press the arrow key down to display the tab canvas.
Trying to use show_view( tab canvas ) in many trigger but still does not show the effect.
Anyone has this experience before ?
Thanks.
