非MFC下如果让edit不能粘贴

[孟如庭]

rt。
没有用MFC。使用了WndProcess，怎么让edit不能粘贴呢？

焦点进入edit中，就拦截不到WM_RBUTTONUP了

子类化 这个 Edit m_hEdit=CreateEdit(hwnd); WNDPROC EdOldProc = (WNDPROC)SetWindowLong(m_hEdit, GWL_WNDPROC, (LONG)EDProc); SetProp(m_hEdit,// handle of window "EditOldProc", // atom or address of string EdOldProc); 、、 LRESULT CALLBACK EDProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) {// get oldproc WNDPROC OldEdProc=(WNDPROC)GetProp(hWnd,"EditOldProc"); char buf[100]= {0}; switch(Msg) { case WM_NOTIFY: // OutputDebugString("notify\n"); break; case WM_KEYDOWN: OutputDebugString("WM_KEYDOWN\n"); break; case WM_KEYUP: OutputDebugString("WM_KEYUP\n"); break; case WM_CHAR: if((TCHAR) wParam==VK_RETURN) { CallWindowProc(OldEdProc, hWnd, Msg, wParam, lParam); POINT pt; DWORD pos; int idx; // insert the indent GetCaretPos(&pt); pos=SendMessage(hWnd,EM_CHARFROMPOS,0,MAKELPARAM(pt.x, pt.y)); idx=LOWORD(pos); SendMessage(hWnd,EM_SETSEL,idx,idx); SendMessage(hWnd,EM_REPLACESEL,0,(LPARAM)" "); return 0; } break; } return CallWindowProc(OldEdProc, hWnd, Msg, wParam, lParam); }

部分代码没看懂，思路理解了。CreateEdit是什么函数，我都没搜到。 WM_RBUTTONUP拦截了，在问下，ctrl+v怎么拦截？

HWND CreateEdit(HWND parentWnd) { HWND hEd=0; hEd = CreateWindow("EDIT", NULL, WS_CHILD | WS_TABSTOP | WS_VISIBLE | WS_BORDER | WS_VSCROLL |WS_HSCROLL | ES_AUTOVSCROLL | ES_AUTOHSCROLL| ES_MULTILINE | ES_WANTRETURN, 4, 250, 300, 80, parentWnd, (HMENU)IDC_EDIT, (HINSTANCE) GetWindowLong(parentWnd, GWL_HINSTANCE), NULL); SetWindowText(hEd," An Edit with ES_MULTILINE and ES_WANTRETURN style!"); // return hEd; }

WM_PASTE WM_COPYDATA 试试拦截这些消息

[信阳毛尖]

ctrl+v怎么拦截 -----------------------

switch(uMsg)
{
case WM_KEYDOWN:
	if(wParam=='V' && GetKeyState(VK_CONTROL)&0x80)
		return;	//直接返回，阻止当前操作
	break;
default:
	break;
}

提醒：粘贴还可以用Shift+Ins

[孟如庭]

竟然还有这个。。。不过我直接拦截WM_PASTE就没问题了
