有懂VB和VC的大虾请来了

[cn2000]

有一个动态链接库（没有LIB文件），在VB中是这样引用的：
Private Declare Function SelectFolder Lib "Convert.dll" (ByVal lpstrFileTitle As _
String, lpcbMaxFileTitle As Long, ByRef lpdwRestoreFlag As Long, ByRef _
lpdwX0 As Long, ByRef lpdwY0 As Long, ByVal lpstrSelectButtonText As _
String, ByVal hParentWnd As Long) As Long

Global Const strSEL_FLD_BUTTON_TEXT = "Select"
Public hWordHandle As Long 'Word's handle for Browse/Progres bar dlg
hWordHandle = GetActiveWindow

Private Function SelectFolderDlg(ByRef strPathDummy As String, _
ByRef lPathSizeDummy As Long) As Long

Dim dwRestoreFlag As Long
Dim dwX0 As Long
Dim dwY0 As Long

dwRestoreFlag = 0 ' default: FALSE
dwX0 = -1
dwY0 = -1

SelectFolderDlg = SelectFolder(strPathDummy, lPathSizeDummy, _
dwRestoreFlag, dwX0, dwY0, _
strSEL_FLD_BUTTON_TEXT, hWordHandle)
End Function
在VC应该如何做呢，恳请各位大侠帮忙。

为什么没有人回答

[gameboy999]

HANDLE hLibrary;
FARPROC lpFunc;
long result;

hLibrary=LoadLibrary("Convert.DLL"); //加载DLL
if(hLibrary>31) //加载成功
{
lpFunc=GetProcAddress(hLibrary,"SelectFolder"); //检取SelectFolder函数地址

if(lpFunc!=(FARPROC)NULL) //检取成功则调用
result=(*lpFunc)(xxx,xxx,xxx,xxxx); //里面跟参数表.....
FreeLibrary(hLibrary); //释放占用的内存
}

我这样做了，但是运行时出错，估计是参数的类型不对，请指教。

按 Function SelectFolder Lib "Convert.dll" (ByVal lpstrFileTitle As _
String, lpcbMaxFileTitle As Long, ByRef lpdwRestoreFlag As Long, ByRef _
lpdwX0 As Long, ByRef lpdwY0 As Long, ByVal lpstrSelectButtonText As _
String, ByVal hParentWnd As Long) As Long 所见会不会是：
typedef long (*fun_in_dll)(char *lpstrFileTitle, long lpcbMaxFileTitle, long *lpdwRestoreFlag, long *lpdwX0, long *lpdwY0, char *lpstrSelectButtonText, long hParentWnd)

func_in_dll lpFunc;
lpFunc=(func_in_dll)GetProcAddress(hLibrary,"SelectFolder");
