Question on RichTextBox, CanUndo and GetCharFromPosi tion(aPoint)

Hi,
Does anyone knows why using GetCharFromPosi tion(aPoint) on RichTextBox
will clear the CanUndo flag? More importantly, How to use
GetCharFromPosi tion and still be able to do Undo?

Thanks
Al

I would like to set up a string array as a class member, or field, and then populate this array by reading in from a text file, but I cannot find the appropriate syntax. The getter and setter are very unhappy with the idea and the compiler refuses to play ball with any of the attempts I have made to build such a structure. There is no problem when using a single string but a two dimensional array of strings appears to be a very different...

There is a hash in my program. The problem is I need to search in the hash, but there are some keys that are identical, but I need to get the associated value of all these keys. when I do something like $value = $hash{ "theKey" }; obviously I'm only getting the value associated to the first key called "theKey". How can I get the others? Some sort of loop? thanks

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
