I am new to GTK and gtkmm. I have been trying to compile an example hello world code for gtkmm which resulted in a gtkmm/button.h: No such file or directory I fixed this by providing the header path, but now I am getting this new error which I am unable to fix.

Answered 2021-Dec-21 at 10:12Your CMake file does not actually use glibmm, it just searches for it.
Here is a modernized version of your libhelloworld/CMakeLists.txt:
QUESTION
I am using C++Builder 10.4.2 with the 64bit compiler. I am trying to parse the nested JSON file below so the "US.NYSE" values are in a TJSONArray, and then loop through them to get each array value. My code does not place the "US.NYSE" into an array. Can you show how to place "US.NYSE" into a TJSONArray? Currently, I can't test the for loop, is this for loop set up correct?
ANSWER
Answered 2021-May-20 at 21:53You have a misunderstanding of how JSON works. I suggest you review the syntax defined by the JSON standard available at https://www.json.org.
There is no array in the JSON you have shown. Arrays are denoted with [] brackets. Objects are denoted with {} braces. So, the top-level JSON value is an Object, the "data“ value is an Object, and the "US.NYSE" is an Object. Thus, the 2 ParseJSONValue() calls will both return a TJSONObject, not a TJSONArray.
There is no need to call ParseJSONValue() the 2nd time, since those inner TJSONObjects are already parsed by the 1st ParseJSONValue() call and are accessible inside of the value hierarchy ofMyjsonFile. Simply typecast the return value of GetValue() to TJSONObject* when accessing those values.
Also, you need to delete the value that is returned by ParseJSONValue() to avoid a memory leak.
Try this instead:

I wrote a shellcode in C that pops a messagebox. I have compiled two variations of it. One says "Hello World!" (shellcodeA) and the other one says "Goodbye World!" (shellcodeB).
...ANSWER
Answered 2021-May-19 at 13:43I don't know where you see the value 0x119, but BYTE bootstrap[12] is a BYTE array.
So assigning bootstrap[i++] = sizeof(bootstrap) + shellcodeALength - i - 4; will store the lowest byte of the expression in bootstrap[i++] and ignore the rest, hence can never go above 255.
You probably want something like this instead:

I have two classes. The base class, called String stores a const char* and the lenght of it, len. The derived class, called UString should has to manage an upperCase static boolean variable. If this is true the string in ostream has to be full uppercase. (this is a university task)

QUESTION
I have made a custom widget and have struggled all afternoon due to the lack of documentation to get a custom object that extends Gtk::Entry to work. I have gotten to the point where I can add the widget in Glade. I am now getting an error:
terminate called after throwing an instance of 'Gtk::BuilderError'
Upon loading. My gdb skills are not excellent but I know that the error is being thrown from auto builder = Gtk::Builder::create_from_file("glade/window_main.glade");
This is what my custom object implementation looks like:
...ANSWER
Answered 2021-Mar-16 at 22:20As it turns out in the course of writing the question I figured out my issue.
I had forgotten to register my custom objects before trying to use them.
I needed to call custom_widgets_init() prior to calling Gtk::Builder::create_from_file("glade/window_main.glade");

Quick question: do I have to / how do I release memory from this allocation of memory?
unsigned char *uString = new unsigned char[4096]();
And if I have to, would I do it like this?
free(uString); delete[] uString;
ANSWER
Answered 2021-Jan-18 at 18:05You use the free function when you allocate memory with the C functions like malloc calloc and more.
In c++ you use the operators new and delete (Also thier array friends new[] and delete[]).
When you want to delete object created with the operator new[], you call the operator delete[].
For example:
QUESTION
recently I got into iOS development and I got a task of examining the application which is already in App Store . But I found something unusual ... Two different users when loging through two different devices through my application which is downloaded from App Store returns same vendor ID ...... is this the expected one ? Because according to the APPLE DOCUMENTS VENDOR ID MUST BE DIFFERENT FOR DIFFERENT DEVICE REGARDLESS OF VENDOR if the app is downloaded from App Store . Please clarify here .
The code which I am using is :
...ANSWER
Answered 2020-Dec-26 at 08:30After several research and practical results I found several characteristic of VendorID:
VENDOR ID will be unique for every device I.e if a same app is downloaded on two devices from App Store , it will surely return different VENDOR ID. VENDOR ID is calculated based on AppStore data in this case
VENDOR ID will be same for every app on a single device which is from same vendor . That is if I have 5 apps from a VENDOR named A in my device .. ALL THESE 5 APPS WILL HAVE SAME VENDOR ID. If we uninstall one app and reinstall again the VENDOR ID will not change . For VENDOR ID to change we must uninstall all 5 apps .
VENDOR ID in newer iOS will also change if we are installing the build using XCODE or development certificate on different device I.e every device will have a different VENDOR ID for same app . In this case vendor ID is calculated based on BUNDLE ID . For older iOS similar BUNDLE ID for 2 apps may produce identical VENDOR ID .
VENDOR ID is always a 32 bit string
VENDOR ID is not a device identifier instead it’s a UUID through this we can’t identify the details about the device
