7 Nov 2018 ... I tried your api to extract text from images using the sample C# code available in github. For the images i tried, the api failed to extract the text. Implicit string conversion is very common in VB, and you often have no idea it has actually happened However, string conversion is expensive and you should avoid it when possible There are some simple steps you can take to minimize the number of string conversions The first step is to use the W versions of the Asc and Chr$ functions Asc must first convert a native UNICODE string into ANSI before it returns the value; AscW simply reads the number currently stored in the string Similarly, Chr$ must convert the number ou give it into a UNICODE number The result is that AscW and ChrW$ are much faster than Asc and Chr$ You should always use the $ versions of string functions whenever they are available If a $ version of a function is available, then its non-$ counterpart actually returns a Variant rather than a String Although the VB compiler is smart enough to avoid duplicating the string when assigning the return value of a Variant function to a String variable, a significant amount of overhead and code generation is involved in using the non-$ functions If you think the extra character is too much trouble, one look at the generated code will cure your laziness Search for $ in the Object Browser to get a list of the $ functions The best-known place where VB performs automatic ANSI/UNICODE conversion is when you send String or fixed-length string variables to Declare functions To seamlessly handle an external world that is often ANSI from within an internal world that is always UNICODE, the VB brain trust decided that all API calls would be considered ANSI When you want an ANSI API call, this situation is wonderful from a coding perspective because you don't have to do any work to make an ANSI API call from VB But from a performance perspective, you add string-conversion overhead at runtime If you write an application exclusively for Windows NT or Windows 2000, which have full UNICODE API support, string conversions for API calls are a waste The downside of implicit conversion is that there is no way to make a Declare statement treat all strings as UNICODE and leave them alone Articles in the VB4 timeframe advocated a ridiculously heavy and complex workaround for calling UNICODE API functions The technique involved copying strings to and from Byte arrays and passing the first element of the Byte array ByRef to the API. asprise-ocr-api c# example: Dynamsoft OCR SDK for .NET microsoft ocr library c# cognitive-services-dotnet- sdk -samples/samples/ ComputerVision at ...

The advantage of the multiple teller model, like that of the multiple process model, is that a failure or grand pause with one server does not impact the others; you get a very rapid failover at the application level or continuity of service through the ultiple back ends Redundancy at the process level has limitations Each process must ensure that it remains independent of others, not moving file pointers or modifying shared file information Output must be coordinated and serialized so that there is no contention from the writing processes If there is intermediate state managed by the worker processes, that state needs to be broadcast to all the processes, since a future request looking for that state information might end up on another process.

Ideally, you want as little state as possible managed on the server side within the application process; state belongs in a database or filesystem where it can be made recoverable, persistent, and easily accessed from any process Note that with multiple processes trying to coordinate read and write access to files, and passing information through the filesystem, you may get better results and fewer development headaches by using a small database table to accomplish the same thing Multiple server processes can run on multiple servers Classic example: httpd daemons running on a web server farm They contain no state that lives beyond the scope of an HTTP connection; they are identical from the point of view of a client, and they are easily replicated If you choose the multiple-server approach for scale or host redundancy reasons, make sure you use a loadbalancing network distribution model as described in 9, Networking.
