I’ve wrote a program, that approximates Pi using the Monte-Carlo method. It is working fine, but I wonder if I can make it work better and faster, because when inserting something like ~n = 100000000 and bigger from that point, it takes some time to do the calculations and print the result. I’ve imagined how ..

How to detect a connection failure in Indy TCP Client Hello, I have made a client and a server using Indy TCPClient and Indy TCPServer (C++Builder 11 Alexandria). I can start the server and connect the client to it correctly but if I set the server ‘MaxConnections’ to a x value and I try to ..
I’m trying to read an integer value from a foreign process with the C++ code below (using C++Builder as IDE). Both applications are 64-bit, but the ReadProcessMemory() function fails with error 299 (ERROR_PARTIAL_COPY). If I compile a second test application and try to read a value from it, it works fine. But I can’t read ..
I recently asked question about how to work with element Edit1 dynamically, now I want to ask something about values, which I received from dynamical arrays. First I try to divide image into sectors: const n=20; unsigned short i, j, line_length, w = Image1->Width, h = Image1->Height, l = Left + Image1->Left, t = Top ..
I needed to divide the picture into sectors and count the number of black dots in each of them. I use regions for this. Can I do this with the Edit input field somehow? HRGN region [n]; HRGN requires a constant value like const n = 35; Please, help if it is possible to somehow ..
I want to measure text width of a TButton so that I can resize it when the text changes. If the button uses ParentFont, I can use the form Canvas to get the width: int GetButtonTextWidth(TForm* form, TButton* btn) { const int base = form->Canvas->TextWidth(btn->Caption); const int margin = 16; return base + margin; } ..
I’m working with 12 year old legacy software written in Embarcadero C++ and I noticed: when you use __func__ or __FUNC__ in debug or release configuration for 32bit, it returns ClassName::FunctionName but when built in debug or release configuration for 64bit, it returns only FunctionName. Is that expected behaviour and can I change that? I’d ..
I built this example to quickly rotate images 90 degrees but I always get a cut of the image on the sides. After many tests, unfortunately I still don’t understand the cause of the problem. void rotate() { Graphics::TBitmap *SrcBitmap = new Graphics::TBitmap; Graphics::TBitmap *DestBitmap = new Graphics::TBitmap; SrcBitmap->LoadFromFile("Crayon.bmp"); DestBitmap->Width=SrcBitmap->Width; DestBitmap->Height=SrcBitmap->Height; SetGraphicsMode(DestBitmap->Canvas->Handle, GM_ADVANCED); double myangle ..
