Applications Interface Programming Using Multiple Languages: by Ying Bai

By Ying Bai

This ebook addresses the necessity for interfaces, or bridges, among the a number of renowned programming languages. With the advance of the complex computing device controls and functions, the one programming language occasionally has a quandary for contemporary complex initiatives. Programmers will often be operating with a number of programming languages at a time and, at the moment, shouldn't have a "bridge" language to tie issues jointly. They spend numerous paintings hours both changing code or operating concurrently on 2 (or extra) varied languages instantaneously. to resolve this challenge and to make use of some great benefits of a number of languages, an interface is required to set a bridge among the various languages. The programming languages coated during this booklet contain: C/C++ and visible C++ 6.0, visible simple 6.0, Java 1.2 and 1.3, Perl, LabView, LabWindows/CVI and size Studio, Matlab, Matlab C/C++ Math library, Matlab compiler and Matlab photo library, and SmallTalk. functional and hands-on programming examples are supplied with every one venture within the e-book. All software examples, that are saved within the connected CD-ROM, were confirmed, debugged and utilized within the real tasks. Readers can simply decide upon the examples to fit their distinct wishes.

Sample text

Y. = 0) msg("ERROR in PortRead()! "); sprintf(cdata, "%d", commClass->pcBuffer[0]); idata = atoi(cdata); delete commClass; return idata; } DllExport int CALLBACK Close() { ERR_CODE rc = OK; if (PortCreateflg) CloseHandle(hPort); PortCreateflg = false; return rc; } ERR_CODE PortInitialize(LPTSTR lpszPortName, pSerialCreate pCreate) { DWORD dwError; 57 58 DCB PortDCB; ERR_CODE ecStatus = OK; COMMTIMEOUTS CommTimeouts; unsigned char dBit; // check if the port has been created... "); return ecStatus; } // Open the serial port.

Functions that are only called from within the DLL may be declared NEAR. The PASCAL or _cdecl calling conventions may be used as appropriate. Functions called from Windows must be declared using the PASCAL calling convention. To summarize, a DLL function called by other applications should be cast by a keyword, FAR PASCAL. In Visual C++, the CALLBACK macro is equivalent to this FAR PASCAL cast. That is why you must place the macro CALLBACK just in front of the DLL function name. We need to do one more thing before we can build our project that is to create a DEF file, or definition file.

WaitCommEvent(hPort, &dwCommModemStatus, 0); // Re-specify the set of events to be monitored for the port. SetCommMask(hPort, EV_RXCHAR|EV_CTS|EV_DSR|EV_RLSD| EV_RING); if (dwCommModemStatus & EV_RXCHAR||dwCommModemStatus & EV_RLSD) { // received the char_event, Loop for waiting for the data. do { // Read the data from the serial port. "); fDone = TRUE; break; } else { // Display the data read. if (dwBytesTransferred == 1) { if (Byte == 0x0D ||Byte == 0x0A) // null char or LF { CommPorts->piNumRcvd = nTotRead; fDone = TRUE; break; } CommPorts->pcBuffer[nTotRead] = Byte; nTotRead++; if (nTotRead == CommPorts->iMaxChars) { fDone = TRUE; break; } } else { if (Byte == 0x0D ||Byte == 0x0A) // null char { msg("Received null character "); fDone = TRUE; break; } } } }while (dwBytesTransferred == 1); //while (nTotRead < pRecv->iMaxChars); } } // while return; } Besides the DLL functions, there are 4 additional local functions implemented in this project.
