以下小弟寫的是一個JNI程式,他會將目前正開啟的process與其記憶體使用率存在一個字元陣列中並回傳,結果卻出現降的錯誤訊息:    [Linker Error] Unresolved external 'GetProcessMemoryInfo' referenced from D:\芭樂專案\GETPROCESSLIST\GETPROCESSLIST_DLL\UNIT2.OBJ    請問這樣的錯誤訊息到底是說明什麼錯誤呢?請各位大大賜教,謝謝!!    #include  #pragma hdrstop #include "Unit2.h" #include "tlhelp32.h" #include "psapi.h" #include #include //------------------------------------------------------------------- #pragma package(smart_init) //------------------------------------------------------------------- JNIEXPORT jstring JNICALL Java_ProcessList_GetProcessList(JNIEnv *env, jobject obj) { char *lastfile; AnsiString temp = ""; HANDLE hProcessSnap=NULL; HANDLE hProcess=NULL; PROCESSENTRY32 pe32={0}; int iProcessCount=0; PROCESS_MEMORY_COUNTERS pmc={0}; hProcessSnap=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); pe32.dwSize=sizeof(PROCESSENTRY32); do { temp = temp pe32.szExeFile; hProcess=OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID); if(hProcess!=NULL) { ZeroMemory(&pmc, sizeof(PROCESS_MEMORY_COUNTERS)); pmc.cb=sizeof(PROCESS_MEMORY_COUNTERS); GetProcessMemoryInfo(hProcess,&pmc,sizeof(PROCESS_MEMORY_COUNTERS)); temp = temp IntToStr(pmc.WorkingSetSize/1024) " K"; } ZeroMemory(&pe32, sizeof(PROCESSENTRY32)); pe32.dwSize=sizeof(PROCESSENTRY32); iProcessCount ; } while(Process32Next(hProcessSnap, &pe32)); CloseHandle(hProcessSnap); lastfile = temp.c_str(); return(env->NewStringUTF(lastfile)); }

georgebig1 你好: 記得要利用 Project Manager 把以下的檔案 Add 到你的專案裡面 C:\Program Files\Borland\CBuilder6\Lib\Psdk\psapi.lib -- Enjoy Researching & Developing --

哇~~~我竟然忽略的這麼重要的一步... 多謝版主的指點!!程式已經可以成功執行了!!
