C++ 生成组合键 WINAPI(无 MFC)

Question

我试图让我的应用程序输出组合键 ( ALT + D ) 以专注于 Internet Explorer 地址栏，但我在实现所需代码时遇到了问题。我已经有一个方法来传递 1 个键:

void GenerateKey(int vk, BOOL bExtended) {

KEYBDINPUT  kb = {0};
INPUT       Input = {0};

/* Generate a "key down" */
if (bExtended) { kb.dwFlags  = KEYEVENTF_EXTENDEDKEY; }
kb.wVk  = vk;
Input.type  = INPUT_KEYBOARD;
Input.ki  = kb;
SendInput(1, &Input, sizeof(Input));

/* Generate a "key up" */
ZeroMemory(&kb, sizeof(KEYBDINPUT));
ZeroMemory(&Input, sizeof(INPUT));
kb.dwFlags  =  KEYEVENTF_KEYUP;
if (bExtended) { kb.dwFlags |= KEYEVENTF_EXTENDEDKEY; }
kb.wVk = vk;
Input.type = INPUT_KEYBOARD;
Input.ki = kb;
SendInput(1, &Input, sizeof(Input));

return;
}

任何人都可以提供一些关于如何实现所需解决方案的帮助吗？

解决方案:

我设法使用以下方法解决了这个问题:

void GenerateKeyCombination(int vk, int vk2, BOOL bExtended, BOOL bExtended2) {

KEYBDINPUT  kb = {0};
INPUT       Input = {0};
KEYBDINPUT  kb2 = {0};
INPUT       Input2 = {0};

// Generate a "key down" 1
if (bExtended) { kb.dwFlags  = KEYEVENTF_EXTENDEDKEY; }
kb.wVk  = vk;
Input.type  = INPUT_KEYBOARD;
Input.ki  = kb;
SendInput(1, &Input, sizeof(Input));

// Generate a "key down" 2
if (bExtended2) { kb2.dwFlags  = KEYEVENTF_EXTENDEDKEY; }
kb2.wVk  = vk2;
Input2.type  = INPUT_KEYBOARD;
Input2.ki  = kb2;
SendInput(1, &Input2, sizeof(Input2));

// Generate a "key up" 1
ZeroMemory(&kb, sizeof(KEYBDINPUT));
ZeroMemory(&Input, sizeof(INPUT));
kb.dwFlags  =  KEYEVENTF_KEYUP;
if (bExtended) { kb.dwFlags |= KEYEVENTF_EXTENDEDKEY; }
kb.wVk = vk;
Input.type = INPUT_KEYBOARD;
Input.ki = kb;
SendInput(1, &Input, sizeof(Input));

// Generate a "key up" 2
ZeroMemory(&kb2, sizeof(KEYBDINPUT));
ZeroMemory(&Input2, sizeof(INPUT));
kb2.dwFlags  =  KEYEVENTF_KEYUP;
if (bExtended2) { kb2.dwFlags |= KEYEVENTF_EXTENDEDKEY; }
kb2.wVk = vk2;
Input2.type = INPUT_KEYBOARD;
Input2.ki = kb2;
SendInput(1, &Input2, sizeof(Input2));

return;
}

然后这样调用它:

        GenerateKeyCombination(0x12, 0x44, FALSE, FALSE);

其中 0x12 是 ALT，0x44 是 D。

将加速器映射添加到您的项目资源，在运行时将其加载到您的应用程序中，并在您的消息循环中添加对 TranslateAccelerator 的调用，然后 TranslateMessage 和 DispatchMessage 才有机会查看它。
