How to select all text in edit control by pressing Ctrl+A? I can catch Ctrl+A for parent window in WndProc. But I don't know how to catch ctrl+a which are applied for edit control. Also I tried to use accelerators, but again it applies only for parent window. Thanks. EDIT: 1-st the simplest method This method Based on @phord's answers in this question: win32 select all on edit ctrl (textbox)
while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
{
if (bRet == -1)
{
// handle the error and possibly exit
}
else
{
if (msg.message == WM_KEYDOWN && msg.wParam == 'A' && GetKeyState(VK_CONTROL) < 0)
{
HWND hFocused = GetFocus();
wchar_t className[6];
GetClassName(hFocused, className, 6);
if (hFocused && !wcsicmp(className, L"edit"))
SendMessage(hFocused, EM_SETSEL, 0, -1);
}
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
EDIT: 2-nd method Need to use CreateAcceleratorTable + TranslateAccelerator functions:
//global variables:
enum {ID_CTRL_A = 1};
HACCEL accel;
//main procedure
ACCEL ctrl_a;
ctrl_a.cmd = ID_CTRL_A; // Hotkey ID
ctrl_a.fVirt = FCONTROL | FVIRTKEY;
ctrl_a.key = 0x41; //'A' key
accel = CreateAcceleratorTable(&ctrl_a, 1); //we have only one hotkey
//How GetMessage loop looks
while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
{
if (bRet == -1)
{
// handle the error and possibly exit
}
else
{
if (!TranslateAccelerator(hWnd, accel, &msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
}
//in WndProc we must add next cases
case WM_COMMAND:
{
if (LOWORD(wParam) == ID_CTRL_A && HIWORD(wParam) == 1)
{
//on which control there was pressed Ctrl+A
//there is no way of getting HWND through wParam and lParam
//so we get HWND which currently has focus.
HWND hFocused = GetFocus();
wchar_t className[6];
GetClassName(hFocused, className, 6);
if (hFocudsed && !wcsicmp(className, L"edit"))
SendMessage(hFocused, EM_SETSEL, 0, -1);
}
}
break;
case WM_DESTROY:
{
DestroyAcceleratorTable(accel);
PostQuitMessage(0);
}
break;
As you can see this is pretty simple.
