mysql - How to use unsigned int / long types with Entity Framework? -

-

with long form data types are mapped correctly when adding a new migration (Code-before), but the Ulm data types are omitted by the eF provider of mysql how a ?

mappings a property to use that entity framework unsigned Does not support data types For the uint column, any one can store the value in a signed data type with a large range (i.e., a long ) is. About ulong column? The general solution could not work for me because there is no EF-supported signature data type that can hold inverted code without any overflow.

After a little bit of thinking, I thought an easy solution to this problem: simply enter the data in the supported long type and if it is accessed then ulong Enter . You might have been thinking: "But wait, Ulong's maximum value & gt; maximum value for long!" You can still store a Ulux bytes in the long run, and then when you need it, revert it, as both of them have 8 bytes. It allows you to save a vulgar variable for a database through EF will allow. 

  // Avoid modifying the following directly // Only used as a database column Public long __MyVariable {received; Set; } // Access / modify this variable. // Tell EF to not map this field to the DB table [Notepad] Public ULLL Permanent {Receive {uncheck (return) __Mearnal;}} set {uncontrolled {__MyVariable = (long) value; < / P> 
 Casting  has been unchecked .  
 
 
 Hope it helps someone to stop the overstalla exceptions.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
