How to configure PHP to emit warning when I try to read value of unset variable?
It is frequently happens when I rename variable in one place, I obtain weird result because I forgot to rename it in other place.
I am trying to deserialize a field:
"presenters":[{...},{...}]
but some of the rows come back with only:
"presenters":""
When the serializer gets to the row with that empty string I get:
Error converting value "" to type 'System.Collections.Generic.List`1[DataPrototype.Model.Presenter]'.
Am I right in thinking that I need a JsonConverter that will change the empty string into an empty List?
I am trying to set the class for an intent to the address listed in a string value, so that I can launch a given activity. The string is composed dynamically during runtime.
Is there anyway to make something like the code below run:
String target=com.test.activity1.class;
Intent intent=new intent();
intent.setClass(this, target);
Thanks
I have a table with three columns: patient_id, obs_date, and weight_val. patient_id stores patient identification #, weight_val stores a weight value, and obs_date stores the date when the weight reading was taken. So, a patient can have many different weight readings at different dates.
How do you write a query for:
select all patients whose last weight reading is 120?
According to the Release Notes:
All user request have an
X-AppEngine-Country header which
contains the ISO-3166-1 alpha-2
country code for the user, based on
the IP address of the client request.
My app is running on localhost with the 1.5.1 Java release which contains the X-AppEngine-Country header but I don't seem to be receiving any value for this header in my requests.
Do I have to deploy the app to a production instance to test this feature?
What is document data store? What is key-value data store?
Please, describe in very simple and general words the mechanisms which stand behind each of them.
I'm reading an article about different evaluation strategies (I linked article in wiki, but I'm reading another one not in English). And it says that unlike to call-by-name and call-by-need strategies, call-by-value strategy is not Turing complete.
Can anybody explain, please, why is it so? If it's possible, add an example pls.

all I can get is a blank prompt:

In NumPy functions, there are often initial lines that do checking of variable types, forcing them to be certain types, etc. Can someone explain the point of these lines? What does subtracting a value from itself do?

I want to set the value of the column 'character_hold' to 'no' for all my rows in my MYSQL database. Is there a SQL statement I can use in phpmyadmin to set them all to 'no'?
I wonder if I could save a value (in my program its an index) so I could call it back when the program launches back again (even if the program destroyed) and the user could start from where finish.

showDescriptionPath is being passed from the previous Tableview. The text shows up, but the entire path prints in the UITextField instead of just the value of "Description" in my plist.
NSString *DescriptionPath = [[NSBundle mainBundle] bundlePath];
NSString *DescriptionInfoPath = [DescriptionPath stringByAppendingPathComponent:showDescriptionInfo];
showDescription.text = [[NSString alloc] initWithFormat:@"%@",DescriptionInfoPath];
Hi,I have a range say,1-100 and i want the user to select a value from this range.Ofcourse showing this with a spinner will be awful.I want to use the functionality of date widget,where we can pick a date by pressing a +/- sign,the longer the press ,higher the iteration speed.
I found numberpicker.java that has the code the date widget uses to get this functionality, but do i have to paste that entire code to achieve this functionality!
