Winapi 弹出菜单不发送WM_命令消息
我正在使用vc6.0。右键单击列表框项目时,我会加载一个弹出菜单。但当我单击POP菜单项时,它似乎没有发送WM_命令消息。在谷歌搜索之后,我对此一无所知。有人知道吗Winapi 弹出菜单不发送WM_命令消息,winapi,visual-c++,contextmenu,visual-c++-6,popupmenu,Winapi,Visual C++,Contextmenu,Visual C++ 6,Popupmenu,我正在使用vc6.0。右键单击列表框项目时,我会加载一个弹出菜单。但当我单击POP菜单项时,它似乎没有发送WM_命令消息。在谷歌搜索之后,我对此一无所知。有人知道吗 void PT_OnContextMenu(HWND hwnd, HWND hwndContext, UINT xPos, UINT yPos) { HWND hList = GetDlgItem(hwnd,IDC_LIST_PRESTYPE); if (hList == hwndContext) {

无法获取下面代码处的消息框
void PT_OnCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify)
{
switch(id)
{
case ID_MENUITEM_RDELTYPE:
{
MessageBox(hwnd,TEXT("dddd!"),TEXT("dddd"),MB_OK);
}
break;
default:
break;
}
}
解决了。找到它了吗
我将hwnd
设置为列表框而不是对话框
A handle to the window that owns the shortcut menu. This window receives all messages
from the menu. The window does not receive a WM_COMMAND message from the menu until the
function returns. If you specify TPM_NONOTIFY in the uFlags parameter, the function does
not send messages to the window identified by hWnd. However, you must still pass a window
handle in hWnd. It can be any window handle from your application.
