kandi X-RAY | ipp Summary
A pure Javascript implementation of the IPP/2.0 protocol that has no dependencies. The IPP protocol was started in the 90's and is still being worked on today. It is a very indepth protocol that spans many RFCs- some of which are dead while others were herded into IPP/v2.x. There are millions of printers that support IPP. If you have one, this module will allow you to send/recieve data to/from the printer.

QUESTION
I have a problem with handling asio::error_code
values when they are received from another dll or executable. For instance, I may run an asynchronous operation with a handler:
ANSWER
Answered 2021-Jun-03 at 14:30This is what I meant with this comment
though boost::system::system_error could invite issues back
The trouble is, error categories are global singleton instances, with object identity (i.e. compared for equality by their address).
You'r ending up with multiple instances in multiple modules. The usual solution is to
- dynamically link to Boost System, so all libraries use the same copy (this does however sometimes run into initialization order issues)
- if that doesn't solve it, make sure all modules actually load the same library (version?)
- In recent boosts I think there's the option to build Boost System completely header-only. This may or may not involve new-fangled C++14 inline, I haven't checked.
If all else fails, do your own translation. There's related issues that might give you ideas:
- Is it possible to convert a boost::system::error_code to a std:error_code?
- Do note that exceptions may run into very similar issues due to RTTI not necessarily matching; exceptions need to be exported types and linked dynamically from the same module for the exception handlers to match the thrown runtime type id.
Is it normal or expected to compare only errorCode.value() against enums?
No it is not. According to some sources Boost as well as standard library promise to map generic error category to errc
which is standard - so you could do that, but you still have to figure out whether that is the category, so doesn't help your scenario.
QUESTION
I am porting some code using Intel IPP lib to OpenSSL (Apple Silicon port).
I have some code checking an XML file signature that looks like this:
...ANSWER
Answered 2021-May-05 at 10:58So after a bit more experimenting, I realised that indeed, ippsRSAVerify_PCKS1v15
and RSA_Verify
expect different data for their respective pMsg
and m
arguments. The Intel function wants to be given the entire message to sign/verify, and computes the SHA1 digest (or other digest) internally, whereas the OpenSSL function expects to be given the digest of the message to sign/verify, not the original message itself.

I have below PowerShell script in my Yaml pipeline, where I am trying to add Path in environmental variable Path, I am not getting any error but my test cases is failing which is dependent on one of the path variable I am setting below.
Is there a way if I can debug and see what all path has been added to my path variable below. If yes how can I see it?? as my test cases pass locally when setting the path env variable.

I have an artifact called onnxruntime.dll which are downloaded from pipeline and its folder structure is like this MyProject_x64_windows/bin/Nodes/onnxruntime.dll . I would like this artifact to be downloaded at one level up i.e. MyProject_x64_windows/bin/onnxruntime.dll
I am not sure how it is getting downloaded at that level and how can I fix this. I cant copy the complete YAML but am providing the one which I think is required:

Answered 2021-Mar-17 at 07:22You can try to set the destination directory in the DownloadPipelineArtifact
task to download the artifact to the bin
folder.

I have an existing Yaml pipeline which I am trying to understand and fix certain things. Since I am new to this, there are few things I am unable to understand in this existing pipeline.

QUESTION
I am trying to show an error whenever one of the fields is not empty...
doing it the old way one field at a time is time and effort consuming... so is there a way to create an array of ErrorProvider
to handle this matter?
and here is the code i have till now...
...ANSWER
Answered 2021-Feb-23 at 13:53As mentioned, you just need a single ErrorProvider
component to report the errors. The ErrorProvider
implements the IExtenderProvider interface to extend the controls in the container and provide additional properties, namely the Error
,
IconAlignment
, and IconPadding
provider properties. So, you just need to set/get their values through the dedicated setter/getter methods.
- ErrorProvider.GetError and ErrorProvider.SetError
- ErrorProvider.GetIconAlignment and ErrorProvider.SetIconAlignment
- ErrorProvider.GetIconPadding and ErrorProvider.SetIconPadding
In your case, create a method to get the controls:
QUESTION
I have a simple form containing fields like Name, City, State, Phone Number, etc. I'm calling a javascript form validation function on submit button click. The validation function is acting strange. Codes written towards the end of the function is not getting executed and the form is getting submitted. However, when I put those codes towards the beginning of the function then those validations are getting executed.
...ANSWER
Answered 2021-Feb-12 at 19:27You return true
in your inputEmail
validation and that is causing the validating function execution to end and form submission to not be stopped when email is valid.
You should put return true;
at the end of the validation function (so after ddlStat
validation).
Also - I highly recommend you to read a bit about code formatting, it will make your code easier to understand: https://standardjs.com/rules.html
QUESTION
I am trying to convert boost::object_pool usage on my old project to new visual studio 2019 project, I am using boost version 1.56
ObjectPool.h
...ANSWER
Answered 2021-Feb-11 at 15:49Frankly, this code cannot have compiled under any compiler.
Note: I'm ignoring numerous typos, omitted semi-colons, omitted
template
declarators, typedefs and access specifiers to focus on the real issues.
You're passing *this
which is Material&
. However, the contruct
[sic] function takes a MaterialServer*
.
So, in fact, the commented line was closer, and makes sense IFF it were a member of MaterialServer
, not Material
.
It would make a lot more sense, logically, for the material server to "create new materials", anyways, and almost works:
