控制台程序实现拖曳运行支持

TCHAR *acDataFile = new TCHAR[MAX_PATH];TCHAR *acTmp = new TCHAR[MAX_PATH];TCHAR *acSourceFile = new TCHAR[MAX_PATH];TCHAR *acResultFile = new TCHAR[MAX_PATH];GetFullPathName(argv[1], MAX_PATH, acDataFile, &acSourceFile);lstrcpyn(acTmp, acDataFile, lstrlen(acDataFile) - lstrlen(acSourceFile) + 1);lstrcpy(acResultFile, Tmp);lstrcat(acResultFile, "Result_");lstrcat(acResultFile, acSourceFile);FILE *hSourceFile,*hResultFile；//……………………//……………………//……………………hSourceFile = fopen(argv[1], "r"); // path is needed.hResultFile = fopen(acResultFile, "a");    

 

将待处理文档（argv[1]）拖曳到exe程序（argv[0]）运行时，argv[0]和argv[1]都带有全路径。

执行fopen时，若赋给fopen的文件名参数不带有路径，则程序的默认路径并非当前路径，而是C:/documents and settings/admin(当前用户名)/，默认路径下找不到argv[1]，于是出错。
