我在下面挂钩了 Winapi EndPaint() 函数，在其中我发送了一些 wm_copydata，但与此同时，我收到“wm_copydata，变量 endpaint_text 周围的堆栈已损坏......”挂钩的应用程序崩溃。
BOOL WINAPI Mine_EndPaint(HWND hWnd, const PAINTSTRUCT *lpPaint) {
BOOL result = fpEndPaint(hWnd, lpPaint);
if (hWnd == g_win)
{
if (lpPaint->rcPaint.left == g_12x && lpPaint->rcPaint.top == g_12y)
{
painting = 0;
wchar_t endpaint_text[MAX_PATH] = L"deleting_a";
COPYDATASTRUCT cds;
::ZeroMemory(&cds, sizeof(COPYDATASTRUCT));
cds.cbData = sizeof(paint_dc);
cds.lpData = endpaint_text;
::SendMessageTimeoutW(g_main, WM_COPYDATA, (WPARAM)::GetDesktopWindow(), (LPARAM)&cds, SMTO_ABORTIFHUNG, 1000, 0);
}
else if (lpPaint->rcPaint.left == g_list12x && lpPaint->rcPaint.top == 137)
{
big_painting = 0;

}
}

{
re_window = NULL;
GetWindowText(hWnd, window_text, MAX_PATH);
if (!wcscmp(window_text, L"Text"))
