具體要怎么修改啊？那個大神幫幫我uj5u.com熱心網友回復：
c++builder，讀寫ini檔案
//包含檔案
#include <inifiles.hpp>
//寫檔案
TIniFile *ini;
ini=new TIniFile(ChangeFileExt(ExtractFilePath(Application->ExeName),"config.cfg"));
ini->WriteInteger("Form","Top",Top);
ini->WriteInteger("Form","Left",Left);
ini->WriteString("Form","Caption",Caption);
ini->WriteBool("Form","InitMax",WindowState==wsMaximized);
delete ini;
//讀檔案
if(FileExists(ExtractFilePath(Application->ExeName)+"config.cfg"))//檢測檔案是否存在
{
TIniFile *ini;
ini=new TIniFile(ChangeFileExt(ExtractFilePath(Application->ExeName),"config.cfg"));
Top=ini->ReadInteger("Form","Top",100);
Left=ini->ReadInteger("Form","Left",100);
Caption =ini->ReadString("Form","Caption","Default Caption");
ini->ReadBool("Form","InitMax",false)?WindowState=wsMaximized:WindowState=wsNormal;
delete ini;
}
else
{
ShowMessage("檔案存在");

同意樓上的，創建一個ini檔案，讀寫ini檔案就可以了uj5u.com熱心網友回復：
經典的用ini，好的串口工具都能講最后一次的設定保存下來供下次初始化uj5u.com熱心網友回復：
有檔案嗎發給我下大哥uj5u.com熱心網友回復：
大哥我也需要這個但是我復制過去的不可以用
uj5u.com熱心網友回復：
大神我也要這個交作業但是不會搞可以幫下嗎
