Assuming that you have no need for floating point exceptions to be unmasked in your application code, far and away the simplest thing to do is to mask exceptions at some point in your initialization code. The best way to do this is as so: SetExceptionMask(exAllArithmeticExceptions); This will set the 8087 control word on 32 … Read more
This allowed me to avoid Eclipse “Unresolved inclusion” error. In my case I had to find the location of the C++ vector header on my computer (which is a Mac): find /usr/local -name vector -print I found the correct include location in folder “/usr/include/c++/4.2.1”. Then I set my project eclipse settings like so: Project->Properties->C/C++ General->Paths … Read more
you are doing this the other way around so there may be present holes in the resulting image because you are looping the source pixels with 1 pixel step …. to remedy this loop the target pixels instead… loop through bitmap2 pixels (x2,y2) for each compute rotated-back (x1,y1) position in bitmap1 copy pixel value if … Read more
This answer is outdated but may be interesting to learn about the technical background. RAD Studio 10.4 Sydney now supports using the Edge browser out of the box. See my other answer. The WebView control is offered via WinRT and does not depend on .net. You can use it from normal Win32 applications. WinRT (Windows … Read more
Nope. But there’s a potential solution: if you enclose your include directive in a namespace of its own, like this… namespace codegear { #include “codegear_header.h” } // namespace codegear …then the effects of any using directives within that header are neutralized. That might be problematic in some cases. That’s why every C++ style guide strongly … Read more
easy, just use TForm::Handle as window handle … Here some ancient example of mine in BCB5 ported to BDS2006: //————————————————————————— #include <vcl.h> #pragma hdrstop #include “Unit1.h” #include <gl/gl.h> #include <gl/glu.h> //————————————————————————— #pragma package(smart_init) #pragma resource “*.dfm” TForm1 *Form1; //————————————————————————— int TForm1::ogl_init() { if (ogl_inicialized) return 1; hdc = GetDC(Form1->Handle); // get device context PIXELFORMATDESCRIPTOR pfd; … Read more
After extensive debugging i finely isolated the problem. Memory management of bds2006 Turbo C++ became corrupt after you try to call any delete for already deleted pointer. for example: BYTE *dat=new BYTE[10],*tmp=dat; delete[] dat; delete[] tmp; After this is memory management not reliable. (‘new’ can allocate already allocated space) Of course deletion of the same … Read more
for TStatusBar, use QStatusBar for TListBox, use QListBox (Q3ListBox in Qt4) or QListWidget TStringGrid and TSpeedButton apparently have no equivalent. Use Qt demo software to see what Qt toolkit proposes and find what you are looking for. For other classes (not mentioned by OP): for TCheckBox, use QCheckBox for TRadioButton, use QRadioButton for TComboBox, use … Read more
