如何在主程序下调用DLL，显示一非模式对话框！！

如何在主程序下调用DLL，显示一非模式对话框！！？
我在dll中实现了显示模式对话框，可是改成显示非模式对话框就会出错，
下面是FaultCheck.dll中的外部函数：
extern "C" __declspec(dllexport) void Test()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
pDlg = new CDialog;
if (pDlg != NULL)
{
pDlg->Create(IDD_DIALOG1);
pDlg->ShowWindow(SW_SHOWNOACTIVATE);

}
}
exe主程序中如下调用：
void CTestDllDlg::OnButton2()
{
typedef void (FAR __cdecl *MYDLL)(void); //

HINSTANCE hinstDLL=NULL; //
hinstDLL=LoadLibrary(GetCurrentDir()+"FaultCheck.dll"); //
if (hinstDLL)
{
MYDLL proc;
proc=(MYDLL)GetProcAddress(hinstDLL,"Test");
if(proc==NULL) AfxMessageBox("can't find function");
else proc();
FreeLibrary(hinstDLL);
}
else
{
AfxMessageBox("FaultCheck.dll装载失败...");
}
}
编译运行时，DIALOG1可以显示，可是马上就windows就会报错！棘手中，请大侠赐教，分不够可再加！

to syy64(太平洋) :
你的意思是要从主程序中将句柄传给dll，不过好象一般不常用这种方式，大多是在dll中自己去获取，但是这样还是出现问题，希望大侠能提供一个demo，我将开贴再送100分！

FreeLibrary 得太早了,用完在 Free

// Note!
//
// If this DLL is dynamically linked against the MFC
// DLLs, any functions exported from this DLL which
// call into MFC must have the AFX_MANAGE_STATE macro
// added at the very beginning of the function.
//
// For example:
//
// extern "C" BOOL PASCAL EXPORT ExportedFunction()
// {
// AFX_MANAGE_STATE(AfxGetStaticModuleState());
// // normal function body here
// }
//
// It is very important that this macro appear in each
// function, prior to any calls into MFC. This means that
// it must appear as the first statement within the
// function, even before any object variable declarations
// as their constructors may generate calls into the MFC
// DLL.
//
// Please see MFC Technical Notes 33 and 58 for additional
// details.

to xing_xing_xing(ζ未名ζ) :
非常感谢，你是对的！大意啊！给分！
to syy64(太平洋):
同样感谢你的支持，不过好象你贴出的代码是模式对话框的！对你倾力相助的精神表示感谢！！！

[njluhao]

另外想问to xing_xing_xing(ζ未名ζ) :FreeLibrary 得太早了,用完在 Free，应该如何free！请到http://community.csdn.net/Expert/topic/4898/4898925.xml?temp=.8572351领分

断言？什么断言？是不是ResourceInstance不对？你的DLL可是MFC的扩展DLL？

[syy64]

extern "C" __declspec(dllexport) void Test(HWND hMainWnd)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
pDlg = new CDialog(CWnd::FromHandle(hMainWnd));
if (pDlg != NULL)
{
pDlg->Create(IDD_DIALOG1);
pDlg->ShowWindow(SW_SHOWNOACTIVATE);

}
}

[njluhao]

to DentistryDoctor(牙医的目标是没有蛀牙)：
是Regular Dlls……

[njluhao]

to syy64(太平洋) :
pDlg = new CDialog(CWnd::FromHandle(hMainWnd));
这句有问题的啊，
CDialog(const char *,class CWnd *)'：cannot convert parameter 1 from 'class CWnd *' to 'const char *'
感谢支持！！！

[njluhao]

论坛和外面的引擎上，我都搜索过了，好象还没有发现完备的方法给出，希望大侠们能给予帮助，整理后加入FAQ，为后来的朋友们提供便利！

[syy64]

写错了，应该这样。
extern "C" __declspec(dllexport) void Test(HWND hMainWnd)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CXXXDlg pDlg(CWnd::FromHandle(hMainWnd));
pDlg = new CDialog();
if (pDlg != NULL)
{
pDlg->Create(IDD_DIALOG1);
pDlg->ShowWindow(SW_SHOWNOACTIVATE);

}
}
