error-handling

问题 all, I am checking the error info in a file in the last line, I would like to have a "yes" result if there is an "Error".

问题 I want to implement the following operator » : throwingFunction(arg: T?)».doStuff() /* if throwingFunction throws an error: print or log the error else returns an object having the doStuff() Method OR An Alternative design that I'm open to is Instead of a throwing Error, the `throwingFunction()` can be swapped out for a method that returns `Result` OR a custom Type, with a generic payload type. */ Here is an example of something similar to what I'm looking for. It is a custom implementation

问题 I have an apache camel rest api which downloads a file from S3. I send json input (key, bucketname, accessKey, secretKey, region) in order to write the URI. The code looks like this: public static class HelloRoute extends RouteBuilder { @Override public void configure() { rest("/") .post("file-from-s3") .route() .setHeader(AWS2S3Constants.KEY, key) .to("aws2-s3://bucketname?accessKey=INSERT&secretKey=INSERT&region=INSERT&operation=getObject") .endRest(); } } I am able to get the respective

问题 I don't know what to do. I want to print out the classifier score but its not working. Can someone Help me? I really don't know what is the problem maybe its something with the Numpy Array ( numpy.arrange ).

问题 I have an Excel VBA function that takes a URL and returns a response (source: getHTTP with VBA?). response = GetHTTP(.ListColumns(colNameURL).DataBodyRange(n).Value) ... Public Function GetHTTP(ByVal url As String) As String With CreateObject("MSXML2.XMLHTTP") .Open "GET", url, False: .Send GetHTTP = StrConv(.responseBody, vbUnicode) End With End Function The function works as expected. However, if there is a problem with the URL (like the server being down), then the VBA editor pops up an

问题 I am not very familiar with MYSQL functions & exception handling. After all the research I could come up with below, but to no gain. I am trying to return 0 if insert statement execution fails and 1 otherwise. Exception is getting raised instead of being handled. Where am i going wrong?

For example, Python has ValueError and the documentation clearly states when to use it.

问题 I've been reading some Microsoft documentation about error handling in VBA and they recommend to include this code in your startup routines to set the appropriate error handling level: Sub SafeStart() Application.SetOption "Error Trapping", 1 End Sub This basically changes this setting inside Tools > Options: I changed the setting manually and it works great.
