在调用对话框的函数开始加入 AFX_MANAGE_STATE(AfxGetStaticModuleState( ));Call this macro to protect an exported function in a DLL. When this macro is invoked, pModuleState is the effective module state for the remainder of the immediate containing scope. Upon leaving the scope, the previous effective module state will be automatically restored.The AFX_MODULE_STATE structure contains global data for the module, that is, the portion of the module state that is pushed or popped. By default, MFC uses the resource handle of the main application to load the resource template. If you have an exported function in a DLL, such as one that launches a dialog box in the DLL, this template is actually stored in the DLL module. You need to switch the module state for the correct handle to be used. You can do this by adding the following code to the beginning of the function:AFX_MANAGE_STATE(AfxGetStaticModuleState( ));This swaps the current module state with the state returned from AfxGetStaticModuleState until the end of the current scope.For more information on module states and MFC, see "Managing the State Data of MFC Modules" inCreating New Documents, Windows, and Views in Visual C++ Programmer’s Guide and Technical Note 58.
void LoadDialog()
{
CTestDlg dlg;
if (dlg.DoModal == IODK)
{
//......
}
}
2。楼上说了
{
CDialog_Connect dlg;
dlg.DoModal();}
我以上方法定义了一个显示对话框的函数，可什么不能显示呢（DLL中）？
