请教一下如何获取Programs and Features里面软件的版本信息，谢谢！

Question

获取Programs and Features里面所有软件的版本信息，并能提取出来driver 和version（比如：Intel
Graphics Driver 21.20.16 ）

Answer 1

 #include <stdio.h>
#include <windows.h>

#pragma comment(lib,"Advapi32.lib")

#define MAX_BUF 1024

int main(int argc, char *argv[])
{ 
    HKEY  hKey;
    char  key_name[MAX_BUF] = {0}; 
    DWORD key_name_len = MAX_BUF;
    const char SubKey[]="SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall";

    if( ERROR_SUCCESS != RegOpenKeyEx(HKEY_LOCAL_MACHINE, SubKey, 0, KEY_ENUMERATE_SUB_KEYS, &hKey))
    {
        printf("打开注册表失败！\n");
        return -1;
    }
    FILE *fp = fopen("D:\\reg_read.txt","w");
    int  i = 0;
    while(ERROR_SUCCESS == RegEnumKeyEx(hKey, i++, key_name, &key_name_len, NULL, NULL, NULL, NULL))
    {
        //printf("OK! %d,%s\n", key_name_len, key_name);
        char buf[MAX_BUF] = {0};
        sprintf(buf,"%s\\%s", SubKey, key_name);
        HKEY hSubKey;
        if( ERROR_SUCCESS == RegOpenKeyEx(HKEY_LOCAL_MACHINE, buf,0,KEY_QUERY_VALUE,&hSubKey))
        {
            //printf("OK! %d,%s\n", key_name_len, key_name);
            BYTE  DisplayName[MAX_BUF]    = {0};
            BYTE  DisplayVersion[MAX_BUF] = {0};
            BYTE  Publisher[MAX_BUF]      = {0};
            DWORD key_value_len           = MAX_BUF;
            RegQueryValueEx(hSubKey, "DisplayName",    0, NULL, DisplayName, &key_value_len);
            key_value_len = MAX_BUF;
            RegQueryValueEx(hSubKey, "DisplayVersion", 0, NULL, DisplayVersion, &key_value_len);
            key_value_len = MAX_BUF;
            RegQueryValueEx(hSubKey, "Publisher",      0, NULL, Publisher, &key_value_len);
            key_value_len = MAX_BUF;

            //printf("%s,%s,%s\n",DisplayName,DisplayVersion,Publisher);
            if(strlen((char*)DisplayName) > 0)
            {
                fprintf(fp,"%s,%s,%s\n",(char*)DisplayName,(char*)DisplayVersion,(char*)Publisher);
            }
            RegCloseKey(hSubKey);
        }

        key_name_len = MAX_BUF;
        memset(key_name,0,MAX_BUF);
    }

    fclose(fp);
    RegCloseKey(hKey);

    return 0;
}

VC++6.0 和 VC++2008编译通过

输出到D:\reg_read.txt，以逗号分隔：
