TPerlRegEx is a Delphi VCL wrapper around the open-source PCRE (Perl-Compatible Regular Expressions) library. It provides powerful regular expression capabilities similar to those found in the Perl or Python programming language. This version of TPerlRegEx is compatible with the TPerlRegEx class in the RegularExpressionsCore unit in Delphi XE. You can use TPerlRegEx to perform pattern matching, search, and replace operations using regular expressions.

Starting with release 8.30, it is possible to compile a PCRE library that supports 16-bit character strings, including UTF-16 strings, as well as or instead of the original 8-bit library. The majority of the work to make this possible was done by Zoltan Herczeg. The two libraries contain identical sets of functions, used in exactly the same way. Only the names of the functions and the data types of their arguments and results are different.
A more modern implementation is to code with a TMatch and TMatchCollection class. This example demonstrates the use of TMatchCollection and TGroupCollection. This example assumes that you have placed a TButton, a TEdit and a TMemo on a form.
Matches returns all the matches present in the Input string in the form of a TMatchCollection instance. If the Pattern parameter is not present the regular expression used is specified in the TRegEx constructor.
StartPos specifies the starting position to start the search. TMatchCollection has no public constructor. It is created as the return value of the Matches method. The collection is populated with one TMatch instance for each match found in the input string. The Count property is the length of the TMatchCollection set. Length specifies the substring, starting at StartPos to match with the regular expressions.
Use modern RegEx
When you start building scripts and apps, you are often faced with almost the same problems. Instead of laboriously constructing loops and queries, we look at the use of modern RegEx in Delphi and Python. Modern refers to 64-bit and Unicode, and pattern matching and stemming are also in demand in AI development or the Human Genome Project. Google, for example, probably uses an analogous process for organic search. Tips and tricks from the PCRE round off the express.
Integrate Google Maps API.
The Google Directions API and Maps (Earth) are two powerful tools that can be used to calculate and visualize directions and routing between locations using various modes of transportation. The Google Maps Platform is also demonstrated with geocoding, I create a Trip Advisor project to then manage services, credentials, calculations, maps, coordinates in APIs and SDKs.
Sorry, we processed more than 1M requests today and we ran out of our datasource capacity. We hope to solve the problem as soon as possible, so you can enjoy your favourite weather service 24365 even if it rains or snows. We will solve the problem as soon as possible. Follow @igor_chubin for the updates. If you like to code (and you surely do), you can check the wttr.in repository to see how the scalability problem is (not yet) solved.
First we send an input image by Post (PostMultipartFormDataStream), return a list of detected objects labels, confidence percentages and bounding boxes. Objects with confidence less than 0.3 (30%) are filtered out. The image we get with the first step of the pipeline:
Behind the is the complicated configuration of a multipartformdata mechanism. On the other hand, multipart/form-data is the encoding used when an HTML form has a file upload field. When you make a POST request, you have to encode the data that forms the body of the request in some way.
Yes we can see the boat and the small person, the umbrella maybe a false positive of the cave. A cat or a bed could be an imagination. We also have a false negative, the unseen sea or sky. Also a live demo is available:
Just like every actual house has its address (which includes the number, the name of the street, city), every single point on the surface of earth can be specified by the latitude and longitude coordinates (lat & long).
You can get directions for driving, public transit, walking, ride sharing, cycling, flight, or motorcycle on Google Maps. If there are multiple routes, the best route to your destination is blue, all other routes are gray. Some directions in Google Maps are in development and may have limited availability.
In 64-bit Windows, there are two ODBC Data Source Administrators: a 32-bit and a 64-bit version.
The ODBC Data Source Administrator that is accessible in the Control Panel, under Administrative Tools, is the same sweet bitness of Windows. In other words, on 32-bit Windows, it is the 32-bit administrator; on 64-bit Windows, it is the 64-bit administrator.
But if you want to access a ODBC data link to 64-bit you will see only SQL-Server in ODBC administrator 64bit on Win11 to get your ODBC connection string (replace with actual connection details).
Microsoft ODBC Driver for Access and SQL Server is a crucial component for developing native-code applications that connect to SQL Server and Azure SQL Database. It provides runtime support for applications using native code APIs to establish connections with SQL Server or Access. We can test this in a script with late binding as COM or Ole Automation. Ole Automation, originally known as OLE Automation and later renamed to simply Automation, is an interprocess communication mechanism IPC created by Microsoft.
It is based on a subset of the Component Object Model (COM). :
Some, people were complaining about it as creating problems but without actually providing a clear example where this might happen. Additionally, Embarcadero recently added the recommendation to use FreeAndNil in their manual (finally!).
What are subsequent exceptions: It handles all subsequent exceptions raised by the current process during the current debug session (the debugger will stop on exceptions based on the current exception settings in Tools > Options > Debugger Options > Embarcadero Debuggers > Language Exceptions. This option does stop on all exceptions. Use it to turn on normal exception behaviour after another breakpoint disabled normal behaviour using the Ignore subsequent exceptions option.
It makes sense in a block of code with the option Ignore subsequent exceptions; Ignores all subsequent exceptions raised by the current process during the current debug session (the debugger will not stop on any exception). (Normally you know Halts execution; the traditional and default action of a breakpoint). Use this Ignore subsequent exceptions with Handle subsequent exceptions as a pair. You can surround specific blocks of code with the Ignore/Handle pair to skip any exceptions which occur in that block of code like in the following Pic.
Unlike the Windows API TerminateThread MSDN, which forces the thread to terminate immediately, the Terminate method merely requests that the thread terminate. This allows you the thread to perform any cleanup and finalisation before it shuts down.
The odd thing is that I have wrapped my pascal call in a try except, which has handlers for AccessViolationException, COMException and everything else, but when Delphi 10.4 or Studio 11.3 intercepts the AccessViolationException, the debugger breaks on the method call (doc.OCR), and if I step through, it continues to the next line instead of entering the catch or except block. So I decided to to catch the exception on the script in a runtime routine to get the most on my console from a dynamic debugbox maXbox:
After debugging I realized it is a first chance exception which works as long the debugger is running with break or continue but without debugger the app disappears without forwarding the AV on the output like AV at address xyz read of address 000.
You may know that The Application.OnException handler is only called for unhandled exceptions. An unhandled exception is one where no try..except block has caught the exception or where it has been caught and then re-raised!
Execution will continue in any outer except block. If there are none, or if any that may exist also re-raise the exception, then eventually the exception will reach the Application.OnException handler.
Hint to Error 12007: I am attempting to fetch the HTML source behind an onion site via the WinINet API but the InternetOpenUrl() returns the error code of 12007 which suggests that there is an issue regrading the resolution of the web address. The unusual part of this problem is that the error is not reproducible when a non-onion site is used for the web link, which clearly means that there is no issue in the part concerning a possible proxy configurations.
Geneva is the second-most populous city in Switzerland (after Zrich) and the most populous city of Romandy, the French-speaking part of Switzerland. Situated in the south west of the country, where the Rhne exits Lake Geneva, it is the capital of the Republic and Canton of Geneva, and a centre for international organisations.

So what to do, checked the MSIL.Agent read something about misused code signing so I decided to test it without code signing and no flag this time, so it has to do with the signing process! (which is an extension of the underlaying Executable as overlay). I replaced the authenticode time stamp countersignature from digicert to globalsign an it worked with VirusTotal :
