not relevant as i wanted to replace that method anyway my man ;P but yes i forgot about that

//Assuming int is on 4 bytes typedef union u { int i; byte b[4]; } U; U x; x.b[0] = 0 // Put first byte here x.b[1] = 0 // second byte here, etc. // Then use x.i as an integer // Keep in mind that on Intel CPUs, integer values are represented in memory in reverse order. // This means that hex value 0x11223344 will be represented in memory as 0x44, 0x33, 0x22, 0x11 // This is called little-endian vs. big-endian representation. // There can be CPUs that uses the other convention. // Make a small test project and play around with some values etc.

Thank Richard

Thank Victor:rose::thumbsup:

If you are also Doug Milne 2021, then you should close one of these accounts.

Why are you using int's through handles and gcnew? Why don't you just say Int32 bytesToRead = 0; Int32 counter = 0; ?? The difficult we do right away... ...the impossible takes slightly longer.

When you get a message like that, one project is compiling for either 32 or 64 bit and the other project is compiling for the opposite. If the target is "Any CPU", a project will compile so that if the code runs on a 64-bit machine, it'll run as a 64-bit process, and if on a 32-bit machine, as a 32-bit process. To solve this, make sure both projects build as either x64 or x86. Which depends on your requirements, but both projects have to build targeting the same thing.

I have never tried, but I would not expect so. If you drag a control onto a form in the designer then the designer adds it to the Form's properties. But there is nothing (at least in C# Forms) that I can see that allows you to modify it to be static.

Then use ToString() with the format specifications. See the example: [Converting Double To System::string^ - C And C++ | Dream.In.Code](https://www.dreamincode.net/forums/topic/98077-converting-double-to-systemstring/)

Hello jsc42, yes I have done this part to prevent the user from ever mistakenly clicking the button :) . Thanks for the suggestion!

Hello, I have made to test() to static and now I have a new error at the same line that doesn't make sense to me. argument of type "void (*)(int, char*)" is incompatible with parameter of type "void (*)(int, char*)" Both the types are identical. I have also tried to change all types to void, and the error message is still the same i.e. argument of type "void (*)()" is incompatible with parameter of type "void (*)()" latest update: problem solved. Please see the first post! thanks!

Thanks Richard, I was just about to delete this post because I just realized that I could do FreeHGlobal(IntPtr(pFullUrl)) as long as pFullUrl is a LONGLONG. Thank you for your response. The difficult we do right away... ...the impossible takes slightly longer.

The only think I could think of is inside ConfigSerialPort.h I should use gcnew for _serialPort _serialPort = gcnew (System::IO::Ports::SerialPort); , and then assign it the parameter _serialPort = serialPort

Hello, thank you very much for your help! I am able to compile after following your suggestion. I will test if this method works and update if this is the final solution. Thanks again! myGroupbox.h #pragma once using namespace System::Windows::Forms; ref class myGroupbox: public System::Windows::Forms::Control { private: System::IO::Ports::SerialPort^ _serialPort; . . .

I fixed my problem already , Updated from array^ to array^.

I have mentioned this following: At the same time, if I tried to declare this myUser^ user1 = gcnew user1 (1002); outside the function , it gives an error syntax error missing ';' before '^' Fortunately, I have solved my problem. It is due to #include function of the class is placed in the .cpp file, instead of the .h file
