[Blog] 在 Blogger 加上程式碼區塊

參見下方連結.
* 如果程式碼中有角括號 (<>)時，要先用 HTML Encoder 進行轉碼再貼上，才不會被編輯器誤認為是要在部落格網頁裏執行的程式碼。

[C++ Builder] FLOAT_INVALID_OVERFLOW!! SetExceptionMask !!

Error FLOAT_INVALID_OVERFLOW occurred when calling a function from a DLL build by VC from C++ Builder? This is a problem of C++ Build and solve if by calling SetExceptionMask before calling your Dll.

Example:

#include <System.Math.hpp>

typedef int (*PFNAddFunction)(int, int);

void testDllCall()
{
  //Mask Exception
  TFPUExceptionMask fExceptionMask ;
  fExceptionMask=GetExceptionMask();
  fExceptionMask << exInvalidOp;
  fExceptionMask <<  exDenormalized;
  fExceptionMask <<  exZeroDivide;
  fExceptionMask << exOverflow;
  fExceptionMask << exUnderflow;
  fExceptionMask << exPrecision;
  SetExceptionMask(fExceptionMask);
  //Call DLL
  HMODULE _dll=LoadLibraryA("dllName.dll");
  if(_dll != NULL) {
    PFNAddFunction myAdd = (PFNAddFunction)GetProcAddress(_dll,"funcAdd");
    myAdd(1,2)
    FreeLibrary(_dll);
  }
}
