我使用動態聯結RAPI.DLL方式想要取得PDA上指定目錄的檔案
先測試CeFindAllFiles 但是回復的值是False
請問我哪裡弄錯了?

原碼如下:

HINSTANCE Hdl;
Hdl = ::LoadLibrary("RAPI.dll"); //載入DLL
WideString szSearchPath;
szSearchPath = ("\\");
DWORD dwFoundCount;
CE_FIND_DATA findDataArray;
/*
const int FAD_NAME =0x4;

typedef struct _CE_FIND_DATA {
DWORD dwFileAttributes;
FILETIME ftCreationTime;
FILETIME ftLastAccessTime;
FILETIME ftLastWriteTime;
DWORD nFileSizeHigh;
DWORD nFileSizeLow;
DWORD dwOID;
WCHAR cFileName[MAX_PATH];
} CE_FIND_DATA, *LPCE_FIND_DATA;

*/

int __stdcall (*CeFindAllFiles)(LPCWSTR,DWORD,DWORD,CE_FIND_DATA); //設定定義函式原型

if(Hdl != NULL) {
CeFindAllFiles = (BOOL __stdcall (*)(LPCWSTR,DWORD,DWORD,CE_FIND_DATA))::GetProcAddress(Hdl,"CeFindAllFiles"); //獲取函數入口地址
if(CeFindAllFiles != NULL) {
if (CeFindAllFiles((LPCWSTR)(szSearchPath),FAF_NAME,dwFoundCount,findDataArray))
{
ShowMessage("能取得RAPI資訊!");
}
else
{
ShowMessage("不能取得RAPI資訊!");
}
} else {
ShowMessage("不能找到函數入口!");
}
::FreeLibrary(Hdl); //一定不要忘記用完后釋放DLL
} else {
ShowMessage("不能載入DLL!");
}

//改用 CeFindFirstFile and CeFindNextFile
/*
typedef struct _CE_FIND_DATA {
DWORD dwFileAttributes;
FILETIME ftCreationTime;
FILETIME ftLastAccessTime;
FILETIME ftLastWriteTime;
DWORD nFileSizeHigh;
DWORD nFileSizeLow;
DWORD dwOID;
WCHAR cFileName[MAX_PATH];
} CE_FIND_DATA, *LPCE_FIND_DATA;//CE_FIND_DATA, *LPCE_FIND_DATA;
*/

int GetRemotePDAFileList(WideString RemotePathName, TStrings* LocalStrings)//-1 false 0 unknow false 1 success
{
HINSTANCE Hdl;
Hdl = ::LoadLibrary("RAPI.dll"); //載入DLL
if (Hdl == NULL)
{
return -1;//ShowMessage("不能載入DLL!");
}
else
{
try
{
HRESULT __stdcall (*CeRapiInit)();//設定定義函式原型
CeRapiInit = (HRESULT __stdcall (*)())::GetProcAddress(Hdl,"CeRapiInit"); //獲取函數入口地址
void __stdcall (*CeRapiUnInit)();//設定定義函式原型
CeRapiUnInit = (void __stdcall (*)())::GetProcAddress(Hdl,"CeRapiUnInit"); //獲取函數入口地址
// BOOL __stdcall (*CeFindAllFiles)(LPCWSTR,DWORD,DWORD,LPCE_FIND_DATA); //設定定義函式原型
// CeFindAllFiles = (BOOL __stdcall (*)(LPCWSTR,DWORD,DWORD,LPCE_FIND_DATA))::GetProcAddress(Hdl,"CeFindAllFiles");
HANDLE __stdcall (*CeFindFirstFile)(LPCWSTR,LPCE_FIND_DATA); //設定定義函式原型
CeFindFirstFile = (HANDLE __stdcall (*)(LPCWSTR,LPCE_FIND_DATA))::GetProcAddress(Hdl,"CeFindFirstFile");

BOOL __stdcall (*CeFindNextFile)(HANDLE,LPCE_FIND_DATA); //設定定義函式原型
CeFindNextFile = (BOOL __stdcall (*)(HANDLE,LPCE_FIND_DATA))::GetProcAddress(Hdl,"CeFindNextFile");
BOOL __stdcall (*CeFindClose)(HANDLE); //設定定義函式原型
CeFindClose = (BOOL __stdcall (*)(HANDLE))::GetProcAddress(Hdl,"CeFindClose");

CeRapiInit();
DWORD dwFoundCount=0;
LPCE_FIND_DATA findDataArray1 = new CE_FIND_DATA[1024];
WCHAR wszFileName[MAX_PATH];
RemotePathName = RemotePathName "\\*.*";
HANDLE MyH1 = new HANDLE;
MyH1 = CeFindFirstFile(RemotePathName,findDataArray1);
if (MyH1 != INVALID_HANDLE_VALUE)
{
LocalStrings->Clear();
LocalStrings->Add(findDataArray1->cFileName);
while (CeFindNextFile(MyH1,findDataArray1))
{
LocalStrings->Add(findDataArray1->cFileName);
}
CeFindClose(MyH1);
return 1;
}
else
{
return 0;
}
}
catch(...)
{
return -1;
}
::FreeLibrary(Hdl); //一定不要忘記用完后釋放DLL
}
}

然後呼叫 GetRemotePDAFileList("\\My Documents",ListBox1->Items); 就會顯示於ListBox1中
