Is there away to run scheduled background job on stateful service in azure service fabric ? the only way I found only was timers & reminders which they run on Actors not stateful service. I'm trying to run scheduled background job to clean up some data in Reliable dictionary.

I am stuck in a problem, don't know if this is related to the current thread.

I have created a rectangle inside the canvas like this:

The grey part is the canvas there is a small rectangle inside. This is the code I have written:

Whenever I am trying to execute a transaction through NodeJS I am getting the error.

I have two Strings

"TOP : Cotton + Embroidered ( 2 Mtr) \nBOTTOM : Cotton + Solid (2 Mtr) \nDUPATTA : Chiffon + Lace Work ( 2 Mtr) \nTYPE : Un Stitched\nCOLOUR : Multi Colour \nCONTAINS : 1 TOP WITH LINING 1 BOTTOM & 1 DUPATTA\nCountry of Origin: India"

and Second one is

"Top Fabric: Cotton Cambric + Top Length: 0-2.00\nBottom Fabric: Cotton Cambric + Bottom Length: 0-2.00\nDupatta Fabric: Nazneen + Dupatta Length: 0-2.00\nLining Fabric: Cotton Cambric\nType: Un Stitched\nPattern: Printed\nMultipack: 3 Top\nCountry of Origin: India"

I need to create python dictionary out of these two strings but with keys which are before colon

for example in string one keys would be

TOP,BOTTOM,DUPATTA,TYPE,COLOUR,CONTAINS,COUNTRY OF ORIGIN

and in second one

keys would be

Top Fabric,Bottom Fabric,Top Length,Bottom Length,Dupatta Fabric,Dupatta Length,Lining Fabric,Type,Pattern,Multipack,Country of Origin

So far i have used

How do you get a specific object from Fabric.js, and determine which one you got? Like calling canvas.getSelectedObject() and then determining if the returned object is an IText or a Circle or something else.

Thanks.

I need to get the number of lines in a Fabric.js Textbox. The text inside the textbox is inputted by the user, and parts of the text can be formatted to bold using [b] and [/b]. This text is then formatted using setSelectionStyles (changing the fontFamily).

I am using Hyperledger Fabric v2.3.1.I am trying to approve my chaincode definition with argument --signature-policy "OR('Org1MSP.peer','Org2MSP.peer')" instead of the default endorsement for the test-network. The whole command is below

I am currently running hyperledger fabric v2.2. I have developed the chaincode using the contractapi and developing the application using fabric-sdk-go/pkg/gateway

How can i get the transaction status and the transaction payload? I am aware of the GetHistoryByKey() which is available in the contractapi but that doesn't works out for my application.

I know there is hyperledger-explorer which can be used to search transactions by TxID but my use-case is my application will be querying by TxID and then it will verify the status of that particular transaction (TxID).

Also, i have tried to achieve this using the fabsdk but i am getting an error when i try to create instantiate the fabsdk using the fabsdk.New(). There seems to be some compatibility issue with the connection-profile.json which i am using the fabric-sample project.

The error which i am getting is:

failed to create identity manager provider: failed to initialize identity manager for organization: MyOrgName: Either a cryptopath or an embedded list of users is required

The same connection-profile has been used in getting the network up and running, and everything seems to be working all good. I am able to submit and evaluate transactions.

SOLUTION

The system chaincodes are embedded in the peer itself. so we need to set the target otherwise it would just give the discovery error since the contract QSCC is not explicitly deployed on the channel.

Make sure to check the core.yaml file channel.system - the system chaincode should be enabled channel.system.qscc: enable
