onsize() 在OnInitDialog() 前运行 如何修改为onsize() 在OnInitDialog() 后运行 呢？

[syy64]

其实你可以用变量来控制对OnSize里的程序的调用。

[jasonshark]

声明一个全局的bool为false, OnInitDialog里置为true,
OnSize里根据这个值进行处理

[折腾_苏州]

我看了你的代码，OnSize()里面 在g_StatusBar调用时候，判断一下句柄是否存在就行了:
if(!g_StatusBar.GetSafeHud())
{
g_StatusBar.....
}

[tdtdtdtdtd123]

其实，我是对作例子敲的，但例子这样是行的 ，而我的偏偏不行呢？
郁闷

[tdtdtdtdtd123]

if (hDialogTemplate != NULL) //在mfc\src\dlgcore.cpp hDialogTemplate=0x0060ce28
lpDialogTemplate = (LPCDLGTEMPLATE)LockResource(hDialogTemplate);
...
if (CreateDlgIndirect(lpDialogTemplate,CWnd::FromHandle(hWndParent), hInst))
//分开
BOOL CALLBACK AfxDlgProc(HWND hWnd, UINT message, WPARAM, LPARAM)
{
if (message == WM_INITDIALOG)
{
// special case for WM_INITDIALOG
CDialog* pDlg = DYNAMIC_DOWNCAST(CDialog, CWnd::FromHandlePermanent(hWnd));
if (pDlg != NULL)
return pDlg->OnInitDialog();//粒子
else
return 1;
}
return 0;
}
//偶的访写 在mfc中变成了
if (CreateDlgIndirect(lpDialogTemplate,CWnd::FromHandle(hWndParent), hInst))
//lpDialogTemplate = 0x00607da0
hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate,
pParentWnd->GetSafeHwnd(), AfxDlgProc);
咋会这样呢？

[思危]

什么意思啊？

[tdtdtdtdtd123]

安不明白，同样的代码，为何产生了不同的执行顺序?

这么多，晕哦
