I am new to swift and trying to figure out how to parse JSON to a struct. I am trying to get an image from NASA Mar's Rover Photos.I am trying to follow tutorials online, but can't seem to fix this issue. What am I doing wrong here?

error:

Fatal error: The data couldn’t be read because it isn’t in the correct format.

Please tell what is wrong with my connection string. I only copy the connection string from azure right now it is showing an error "Format of the initialization string does not conform to specification starting at index". When I tried to replace the double quote with single quote it says the it is missing the providerName attribute but the provider name is already included. My connection string, also I am using Entity Thank you. I know this has been asked before but I couldn't see what is wrong. What am I missing?

I developed locally using SQL Server and am attempting to get it working in AWS.

I installed the "AWS Toolkit for VS2019" and published to AWS Elastic Beanstalk.

I modified the code to grab the connection properties as explained in https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_NET.rds.html

I also created the database and populated it with data.

I loaded the Pomelo.EntityFrameworkCore.MySql NuGet package.

When I call a test "Hello World" api function it returns Hello World.

When I attempt to call a function that accesses the database the first error I get is

Keyword Data Source not expected in the connection string.

If I refresh the browser I get this next error

The operation cannot be completed because the DbContext has been disposed.

I'm not sure what the provider and providerName sections should be or how it should be set using AppSettings to determine the connection string.

I'm trying to click this button, but the button is actually an image which doesn't have an ID. I've tried using the Xpath by doing

I am suddenly getting this error, on production, in my log file:

System.Web.HttpException (0x80004005): Exception of type 'System.Web.HttpException' was thrown.

System.Web.HttpException (0x80004005): Unable to connect to SQL Server session database.

System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

I looked at a lot of other answers like here

but I don't have connections leak and I don't want only to set the max pool to 200 or so because I want to understand why I suddenly get this exception...

These are my connection strings:

I've read and reread articles online on how to do this, but it's probably something simple. I'm trying to learn how to process a json response from an API call. I have a simple method I call from Main()

I have looked through various posts related to this problem, but none provide an answer. I created a .Net 5.0 app that accesses an Azure SQL DB using EF 6.4.4 which works with .Net standard libraries. I modified the EF by adding a function that creates the connection string from appsettings.json since .Net 5 apps don't use a web.config file. This also works well in Azure with the configuration settings in an app service.

The connection string looks like this:

My objective is to create a 1D/2D lookup table that can read a variable sized array in JSON file without having to specify a statically sized Modelica array parameter.

I started out by trying to extend ExternData to implement a custom table based on a suggestion in a github issue: https://github.com/modelica-3rdparty/ExternData/issues/34#issuecomment-718552210

The steps outlined were:

• Create your own copy of a CombiTable, modify it to accept a data access object and a stable name, see code snippet below
• Create a duplicate of the ExternalCombiTable1D, which instead references your own CombiTable data object
• Create a c-function which reads the data directly from the json and stores it into a table object, which is then passed to the MSL function ModelicaStandardTables_CombiTable1D_init2

I've implemented all three steps to make a custom CombiTable1D block which populates a dynamic sized table from ExternData JSON functions. Package code below:

https://github.com/vsskanth/ExternData.CustomTable

In this package, there are 3 experiments of relevance to this issue. All experiments compile but only only one experiment works:

• ExternData.Examples.JSONTestVariableArrayBroken.mo - Single instance of custom CombiTable1D - does not initialize
• ExternData.Examples.JSONTestArrayCombi2DBroken.mo - Custom CombiTable1D and instance of Modelica CombiTable2D - does not initialize
• ExternData.Examples.JSONTestVariableArrayWorking.mo - Custom CombiTable1D and a couple instances of Modelica CombiTable1D - works as expected

I am trying to find out why my custom CombiTable1D implementation initializes and runs only when there is at least one instance of Modelica CombiTable1D present in the experiment. I made sure to link ModelicaStandardTables.h and ModelicaStandardTables.lib libraries in my own implementation, checked for warnings in dsbuild.txt and compilation seems to be fine.

For some reason, the constructor function for the custom ExternalCombiTable1D external object (ExternData.Types.ExternalCombiTable1D) does not return and hence the custom CombiTable1D block (ExternData.Tables.CombiTable1D) is not able to initialize when there are no instances of Modelica CombiTable1D tables in the model.

I would appreciate any thoughts on why this is happening and how to overcome it.

I am writing a program in Python that communicates with a spectrometer from Avantes. There are some proprietary dlls available whose code I don't access to, but they have some decent documentation. I am having some trouble to find a good way to store the data received via callbacks.

Basically, the dll contains a function that I have to call to start measuring and that receives a callback function that will be called whenever the spectrometer has finished a measurement. The function is the following:
