SDK非模态对话框问题求助!

[stackoverlow]

想用非模态对话框实现个计算器，加上加速键键盘接口，结果弄好之后不但加速键没用，连用鼠标也失效了。。
求助求大神解决看看我代码哪里有问题啊？先谢谢了，下面是界面的主要代码

#include <windows.h>
#include "core.h"
#include "resource.h"

我也新手,说的不一定对

这个计算器,如果模态对话框的话,正确吗?

模态对有内建的消息循环,只需要自己写对话框消息过程就可以了
非摸态对话框,不仅要自己写对话框消息过程,还要自己写消息循环,就类似主窗口的消息循环那样

建议LZ 先试试改成模态的好用不好用

饿....

LZ 的程序好像只有一个窗口,当我楼上的话没说....

已经做好了的模态的能行，我是想改成非模态的，这样才能加加速键。。。但是改了之后就不行了

[aiyaya730]

为什么只有非摸态才能加加速键?
摸态的也可以吧

我感觉既然摸态的可以,非摸态的不可以,
问题肯定是处在消息循环上了

dlghwnd = CreateDialog (hInstance, MAKEINTRESOURCE(IDD_DIALOG), 0/ * hwnd */, DialogProc) ;

求助啊各位帮看看怎么解决。。

把

	while (GetMessage (&msg, NULL, 0, 0))
	{
		if (!TranslateAccelerator (hwnd, hAccel, &msg))
		{
			TranslateMessage (&msg) ;
			DispatchMessage (&msg) ;
		}
	}

改为

 while (GetMessage(&msg, NULL, NULL, NULL)) 
{ 
    if (!IsWindow(hwnd) || !IsDialogMessage(hwnd, &msg)) 
    { 
        TranslateMessage(&msg); 
        DispatchMessage(&msg); 
    } 
}

非模态对话框的消息有IsDialogMessage函数来传递和处理
