C Builder修改 Registry Table 的問題 2000-08-16 14:11:52 摘自《賽迪網》 /文 作者不詳 RootKey是Registry Table 的Root 鍵值﹐比如執行regedit後看到的HKEY_USERS,HKEY_LOCAL_MACHINE就是RootKey,在TRegIniFile中缺少的RootKey 是HKEY_USERS. 下面的例子是TRegistry的﹐TRegIniFile也差不多 void __fastcall TfrmMainForm::WriteToMyRegistry(int table_count) { //TODO: Add your source code here TRegistry *MyRegistry=new TRegistry; MyRegistry->RootKey=HKEY_LOCAL_MACHINE; //改變缺少Rootkey if(!MyRegistry->OpenKey("Software\\Microsoft\\Windows\\Current\ Version\\Run",true)) //改變 Run 的鍵值為True //這樣雙引號裡面的東西就變成了CurrentKey { Application->MessageBox("Registry Table 內容無效", "讀取Registry Table 錯誤",MB_ICONERROR); MyRegistry->CloseKey(); delete MyRegistry; return; } MyRegistry->WriteString("myrun","c:\\sthvcd\\sthvcd.exe"); MyRegistry->CloseKey(); delete MyRegistry;
