C++利用注册表添加桌面右键新建菜单
海胖子 - 2014/02/23对于程序员来说,新建一个cpp文件是再频繁不过的事情了。 为了方便,我们习惯在桌面右键新建文件,而不是新建一个文本文档,然后修改后缀名。 百度谷歌查询了一下,终于知道如何添加注册表。 手痒,抽出时间用cpp写了一个程序,方便以后操作。 客户需求是永远无法满足的,经同学测试,陆续写了三个版本。 接下来直接贴代码~
第一个版本,只能添加c、cpp、java三种后缀。
第二个版本,精简了代码,支持添加用户输入的后缀。/* * Author: Haipz * School: HDU * File Name: registry1.0.cpp */ #include <cstdio> #include <cmath> #include <ctime> #include <cctype> #include <cstring> #include <cstdlib> #include <climits> #include <cfloat> #include <iostream> #include <vector> #include <stack> #include <queue> #include <set> #include <map> #include <algorithm> using namespace std; char s[1024], buffer[128], result[1024*4]; void work_1() { system("reg add \"HKEY_CLASSES_ROOT\\.c\\ShellNew\" /v \"NullFile\" /t REG_SZ"); } void work_2() { system("reg add \"HKEY_CLASSES_ROOT\\.cpp\\ShellNew\" /v \"NullFile\" /t REG_SZ"); } void work_3() { system("reg add \"HKEY_CLASSES_ROOT\\.java\\ShellNew\" /v \"NullFile\" /t REG_SZ"); } int main() { printf("Add registry for C, C++ and Java\n"); printf("Author: Haipz\nSchool: HDU\n"); printf("1 for C;\n2 for C++;\n3 for Java.\n"); printf("Example: 12 to add C and C++.\n"); printf("Please make choice(s): "); gets(s); for (int i = 0; s[i] != '\0'; ++i) { printf("Working...\n"); if (s[i] == '1') work_1(); else if (s[i] == '2') work_2(); else if (s[i] == '3') work_3(); else printf("%c is a wrong enter!\n", s[i]); } system("pause"); return 0; }
第三个版本,支持多次添加,并允许删除已添加的注册表。/* * Author: Haipz * School: HDU * File Name: registry2.0.cpp */ #include <cstdio> #include <cmath> #include <ctime> #include <cctype> #include <cstring> #include <cstdlib> #include <climits> #include <cfloat> #include <iostream> #include <vector> #include <stack> #include <queue> #include <set> #include <map> #include <algorithm> using namespace std; char a[1024]; char b[1024] = "reg add \"HKEY_CLASSES_ROOT\\."; char c[1024] = "\\ShellNew\" /v \"NullFile\" /t REG_SZ"; void work(char* a) { strcat(b, a); strcat(b, c); system(b); } int main() { printf("Function: Add registry to build a new file simply!\n"); printf("Author: Haipz\nSchool: HDU\n"); printf("Example: Enter c to add C and enter cpp to add C++.\n"); printf("Your opion: "); gets(a); work(a); system("pause"); return 0; }
