I'm having a problem with set function in MatLab gui I'm getting this error :
Invalid handle object.
there is my code:
[value index] = min( CostFunction(params, ...
input_layer_size, ...
hidden_layer_size, ...
num_labels, ...
X, y, lambda));
set(handles.cfwoText,????,value);
Value returned from [value index]is type double ex:1.4563e-011,and I want to show it on EditText called cfwoText,but i dont know what type should I write in ?
I believe a simple google search will provide an answer.
In addition, in GUIDE you can write click your Edit Text and choose Property Inspector. You will see all the properties.
Having said that, what you are looking for is
set(handles.cfwoText,'String',num2str(value));
Note that num2str is required since value is double and the text is string.

I have an xml
<family>
<child_one>ROY</child_one>
<child_two>VIC</child_two>
</family>
I want to fetch the value from the XML based on the dynamic tag in ESQL. I have tried like this
SET dynamicTag = 'child_'||num;
SET value = InputRoot.XMLNSC.parent.(XML.Element)dynamicTag;
Here num is the value received from the input it can be one or two. The result should be value = ROY if num is one and value is VIC if num is two.
The chapter ESQL field reference overview describes this use case:
Because the names of the fields appear in the ESQL program, they must be known when the program is written. This limitation can be avoided by using the alternative syntax that uses braces ( { ... } ).
So can change your code like this:
SET value = InputRoot.XMLNSC.parent.(XMLNSC.Element){dynamicTag};
Notice the change of the element type as well, see comment of #kimbert.
Below is the code which i have been trying to address the below UseCase in JMETER.Quick help is appreciated.
Usecase:
A particular text like "History" in a page response needs to be validated and the if the text counts is more than 50 a random selection of the options within the page needs to be made.And if the text counts is less than 50 1st option needs to be selected.
I am new to Jmeter and trying to solve this usingJSR223 POST processor but somehow stuck at vars.put function where i am unable to see the desired number being populated within the V paramter.
Using a boundary extractor where match no 1 should suffice the 1st selection and 0 should suffice the random selection.
def TotalInstanceAvailable = vars.get("sCount_matchNr").toInteger()
log.info("Total Instance Available = ${TotalInstanceAvailable}");
def boundary_analyzer =50;
def DesiredNumber,V
if (TotalInstanceAvailable < boundary_analyzer)
{
log.info("I am inside the loop")
DesiredNumber = 0;
log.info("DesiredNumber= ${DesiredNumber}");
vars.put("V", DesiredNumber)
log.info("v= ${V}");
}
else{
DesiredNumber=1;
log.info("DesiredNumber=${DesiredNumber}");
vars.put("V", "DesiredNumber")
log.info("v= ${V}");
}
def sCount = vars.get("sCount")
log.info("Text matching number is ${sCount_matchNr}")
You cannot store an integer in JMeter Variables using vars.put() function, you either need to cast it to String first, to wit change this line:
vars.put("V", DesiredNumber)
to this one
vars.put("V", DesiredNumber as String)
alternatively you can use vars.putObject() function which can store literally everything however you will be able to use the value only in JSR223 Elements by calling vars.getObject()
Whenever you face a problem with your JMeter script get used to look at jmeter.log file or toggle Log Viewer window - in absolute majority of cases you will find the root cause of your problem in the log file:
Trying to show/hide a couple of rectangles in SSRS based on an expression which uses the value of a parameter in the report. See the screenshots for more details. When the '-Cover pages' label is picked I want it to display the rectangle but I consistently get the following errors. It can't seem to convert and read the parameter expression no matter what I do.
The expression I'm trying to use is:
=iif(Parameters!specparam.Value="-Cover Pages",true,false)
It looks like the label of your parameter is what you're looking for based on the image provided and your expression. Try to switch instead to:
=IIF(Parameters!specparam.Label="-Cover Pages",TRUE,FALSE)
(Note: I switched specparam.Value to specparam.Label.
Your comment is very close. Apply this expression to the Hidden property of the rectangle:
=IIF( Parameters!specparam.Label.Equals("-Cover Pages"), FALSE, TRUE )
You'll notice I have switched around the FALSE and TRUE as you don't want the rectangle to hide when the parameter matches.
Edit:
As you're dealing with a multivalue parameter, you can use a combination of Array.IndexOf and Split to check if your value is one of the selected parameters.
Apply this expression to the Hidden property of your rectangle:
=IIF( Array.IndexOf( Split( Parameters!specparam.Value, "," ), "-Cover Pages" ) > -1, FALSE, TRUE )
I have a simple TextBox in my Precision Design related to a Field in Temporary Table.
I need to show this TextBox only If the it value under Temporary Table is pupulated : so if the value field is pupulated (is a string) I show the Text Box , otherwise I don't show the text Box.
I need to set Visibility by Expression :
Which is the best way forward over ?
Thanks!
You can use iif function. Press fx button, here you can writte your code.
iif function evaluate a condition and return 1 of 2 options, for example, in your case you need show one value only if exist.
check this code:
=iif(fields!YourFieldName.value = "", true, false)
if your field is a number
=iif(fields!YourFieldName.value = 0, true, false)
This code evaluate the value of your field and only populate the value if is complete.
I'm getting this error when trying to build the app:
<unknown>:0: error: cannot assign value of type 'Array<_>' to type 'Array'
but Xcode is not indicating a specific line or class for the failure.
If I could understand the difference between
Array<_>
&
Array
it may help me locate the issue.
When you app is crashing, than you can turn on All Exceptions for Debug breakpoint. This should stop on the line where the crash appears.
You find this in Xcode on the Left Panel-> BreakPoint Navigator.
Than press the + in the bottome left corner and Add Exception Breakpoint.
It looks like that you overwrite an array with an array that has a specific value definition. Good Luck :)
A generic argument clause is enclosed in angle brackets ( < > )
< generic argument list >
You can replace a type parameter with a type argument that is itself a specialized version of a generic type.For example, you can replace the type parameter T in Array < T > with a specialized version of an array, Array< Int > , Array< String >, to form an array whose elements are themselves array of integers / Strings
Regarding xour code Snippet the fix is:
u should define it with the right value ... userTweetsArray : [String] = String . or remove the : [String] because setting the value defines already the object and type :)
I don't like answering my own questions but for the sake of closure
I had this line of code
var userTweetsArray : Array = [String]()
I never actually used it. Once I removed that line the error had gone.
The error was caused by assigning an array of a type in this case String to an Array of no type.
So difference is Array<_> is an array of a type and Array is not.
