MFC Dialog报错问题，m_hWnd为空 <b> ?报错
代码如下：
BOOL CVSOConnectorApp::InitInstance()
{
//m_pMainWnd = (CWnd*)malloc(sizeof(m_pMainWnd));
INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);
char buf[MAXBUFSIZE + 1];
char value[MAXPARAMETERLEN + 1];
CVSOConnectorDlg dlg;//报错地方，debug模式下只要执行到这就会报错，release下是ok的
m_pMainWnd = &dlg;
错误信息如图

CVSOConnectorDlgdlg;dlg.DoModal()CVSOConnectorDlgdlg;
dlg.Create(对话框资源id);有的，
CVSOConnectorDlg*dlg=newCVSOConnectorDlg;
m_pMainWnd=dlg;dlg->serverdetails.setServer(sd.getServer());dlg->serverdetails.setPort(sd.getPort());dlg->serverdetails.setUsername(sd.getUsername());dlg->serverdetails.setPassword(sd.getPassword());dlg->serverdetails.setDomain(sd.getDomain());dlg->serverdetails.setGatewayHostname(sd.getGatewayHostname());dlg->serverdetails.setFullScreen(true);if(pShellManager!=NULL){deletepShellManager;}returndlg->Create(IDD_VSOCONNECTOR_DIALOG);m_hWnd还是m_pMainWnd为空？
m_pMainWnd是什么类型要看一下CVSOConnectorDlg类的构造函数中写了什么
将dlg换成CVSOConnectorDlg*，或者全局变量。
