I've worked with struct when I used WinINet DLL. Here's an exemple when I try to find a filename in an FTP session.
***CODE BEGIN Binary findFiledata = new Binary(512); // WIN32_FIND_DATA struct Binary dwContext = new Binary(4); // DWORD size dwContext.word(0, 0); // Here I pass the pointer to findFiledata // the dll fills findFileData with WIN32_FIND_DATA struct _ftpFindFirstFile.call(_intSessHandle, lpszSearchFile, findFiledata, 0, dwContext); // The file found is in findFileData, we just need to extract it // I know that the file name is located at 0x2C in the struct and // length is 260 info(substr(findFiledata.string(0x2C), 1, 260)); ***CODE END Since you cannot declare struct in Axapta the same way you can in C, it's a bit more work, but you can also create a class that will encapsulate all the struct management. If you need more info about this, let me know.
