win32，创建两个非模态对话框但有一个不能退出、按钮无法响应、无法移动（分数不多了，无法给太多分。但是希望大家帮忙解决，谢谢。）

CreateDialog The CreateDialog macro creates a modeless dialog box from a dialog box template resource. The CreateDialog macro uses the CreateDialogParam function. HWND CreateDialog( HINSTANCE hInstance, // handle to application instance LPCTSTR lpTemplate, // identifies dialog box template name HWND hWndParent, // handle to owner window DLGPROC lpDialogFunc // pointer to dialog box procedure );

我记得对话框的DlgProc窗口过程最后需要return FALSE;

不行

引用 2 楼 Minikinfish 的回复:

Windows程序很简单，就几点内容 1、窗口需要注册， 2、注册需要proc 3、proc需要循环泵的支持 4、大量窗口的api 5、SetWindowLong WGL_DLGPROC 可以对窗体任意修改

这个我知道，我现在需要直接加载RC资源中的对话框，因此 custommessage.commonvariables.hMainWnd = CreateDialog(custommessage.commonvariables.hInst, MAKEINTRESOURCE(IDD_DIALOG_WNDPROC), 0, (DLGPROC)WndProc); 在回掉函数WndProc中，点击高级搜索后弹出搜索的对话框， case IDB_WNDPROC_SEARCHALLDLGDOWN: { custommessage.commonvariables.hSearchWnd = CreateDialog(custommessage.commonvariables.hInst, MAKEINTRESOURCE(IDD_DIALOG_ALLSEARCH), 0, (DLGPROC)AllsearchProc); // hWnd也不成 ShowWindow(custommessage.commonvariables.hSearchWnd, SW_SHOW); } break; 其中AllsearchProc与WndProc所对应的两个对话框不是父子关系，而是同等关系。但是点击AllsearchProc中的关闭按钮、移动、点击搜索按钮 case IDB_SEARCH_ALLSEARCH: { DestroyWindow(hWnd); hWnd = NULL; } break; 都不响应消息。 而且我也用WM_SYSCOMMAND来实现关闭操作，仍然没反应。 case WM_SYSCOMMAND: { if(wParam == SC_CLOSE) { DestroyWindow(hWnd); hWnd = NULL; } } break; 不知道为什么.
