组合键(ctrl + v + c ...)用于OnKeyDown [英] Combine Key (ctrl+v +c ...) for OnKeyDown

问题描述

您能告诉我如何编写组合键(如ctlr + v)的代码吗?

例如:

Can you tell me how to write code for combine key like ctlr + v.

For example:

OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if(nChar == VK_DELETE) //this is ok
//do something

//but if we press control + v how to process it

if(nChar == VK_CONTROL // +, &, | 0x56

我尝试了GetKeyState和GetASyncKeyState，但结果不好

i tried GetKeyState and GetASyncKeyState but the result is not good

if(nChar == 0x56)
    {
    if((GetAsyncKeyState(VK_CONTROL) & 0x8000) == 0)
        {
        MessageBox(_T("test thu"));
        }
    }

我用Google搜索了这是我的问题，但找不到任何有用的方法.
请帮帮我！

This is my problem, i googled, but cant find anything helpful.
pls, help me out!

推荐答案

在WM_KEYDOWN消息中，您应该使用GetKeyState(). GetAsyncKeyState()用于WM_KEYDOWN处理程序外部的代码.

Win32:

During a WM_KEYDOWN message you should use GetKeyState(). GetAsyncKeyState() is for code outside a WM_KEYDOWN handler.

Win32:

case WM_KEYDOWN:
    if (wParam == 'V')
    {
        if (GetKeyState(VK_CONTROL)<0)
            MessageBoxA(hWnd, "TEXT", "CAPTION", MB_OK);
    }

您的代码经过修改:

Your code with modifications:

if(nChar == 'V')
{
    // you could also say "if (GetKeyState(VK_CONTROL) & 0x8000)"
    if (GetKeyState(VK_CONTROL) < 0)
        MessageBox(_T("test thu"));
}
