我的程序中有一个嵌入式控制台。当主窗口未激活且在控制台中单击时,不会将主窗口置于前面。在spy ++中,没有任何消息在点击控制台时发送到主窗口。
以下是说明问题的示例:
#include <windows.h>
#include <iostream>
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nShowCmd)
{
static TCHAR lpszAppName[] = TEXT("HelloWin");
HWND hwnd;
MSG msg;
WNDCLASS wc;
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wc.lpszMenuName = NULL;
wc.lpszClassName = lpszAppName;
if (!RegisterClass(&wc))
{
MessageBox(NULL, TEXT("This program requires Windows NT!"),
lpszAppName, MB_ICONERROR);
return 0;
}
hwnd = CreateWindow(lpszAppName,
TEXT("The Hello Program"),
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);
ShowWindow(hwnd, nShowCmd);
UpdateWindow(hwnd);
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_CREATE:
{
AllocConsole();
freopen("CONOUT$", "w", stdout); // redirect std::cout to console
std::cout << "test console" << std::endl;
// get console handle
HWND console = GetConsoleWindow();
SetParent(console, hwnd);
ShowWindow(console, SW_MAXIMIZE);
}
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd, message, wParam, lParam);
}
是否可以通过单击控制台激活主应用程序?
