得到電腦的資訊

這裡有幾個函式，用來得到機器的資訊：

1、得到登錄檔鍵值：這裡判斷norton的病毒庫版本

void cinfoshowdlg::getnortonversion()

dword datalen,type;

byte data[80];

result = regqueryvalueex(hkey,"patternfiledate",null,&type,data,&datalen);

if (result != 0)

char tmp;

int years,months,days;

tmp = data[0];

years = tmp%10;

tmp = data[1];

months = tmp + 1;

tmp = data[2];

days = tmp;

m_norton_version.format("200%d.%d.%d",years,months,days);

regclosekey(hkey);

}2、硬碟空間：

cstring cinfoshowdlg::getdisk(char *disk)

free_space = result_freespace.quadpart/1024/1024;

total_space = result_totalspace.quadpart/1024/1024;

free_percent = (float)free_space/total_space*100;

disk_space.format("%dm/ %dm (%d%%)",free_space,total_space,free_percent);

if((hostinfo = gethostbyname(name))!=null)

}wsacleanup();

}m_ipaddr = ip;

m_hostname.format("%s",name);

}4、網路狀態：建立乙個socket，ping自己。

int cinfoshowdlg::get***state()

memset(&pingsocket, 0, sizeof(pingsocket));

pingsocket.sin_family      = af_i***;

pingsocket.sin_addr.s_addr = i***_addr(m_ipaddr);

pingsocket.sin_port        = htons(ping_port);

confd = socket(af_i***, sock_stream, 0);

error = connect(confd,(struct sockaddr *)&pingsocket,sizeof(sockaddr_in));

error = send(confd,"!",1,0);

if(error == 0)

m_***_state.format("on");

updatedata(false);

return 0;

}

得到指定檔案的資訊

char szfilename c enochshen.exe dword dwsize getfileversioninfosize szfilename,null lpvoid pblock malloc dwsize getfileversioninfo szfilename,0,dwsize...

C 得到磁碟資訊

得到輪廓點的座標資訊

vv contours裡面就是輪廓點的座標資訊 for int i 0 i 如果你要獲取輪廓內部的點 那你演算法用錯了，contour是找邊緣。你要用的是blob，連通域。基於contour做乙個區域蔓延法就行。opencv如何獲取指定圓上所有畫素點的座標 csdn論壇 或者簡單點 建立一副尺寸夠大...
