Find Window Tittle then Close

Posted: Mar 26, 2018 12:33 PM

findwindow , sendmessage , hwnd

//test1 failed
HWND MyHandle;
MyHandle = FindWindow((wchar_t*)"Properties",NULL);
SendMessage(MyHandle, WM_CLOSE, 0, 0);

//test2 failed
HWND Find = ::FindWindowEx(0, 0, (wchar_t*)"Properties", 0);
SendMessage(Find, WM_CLOSE, 0, 0);

in Delphi the FindWindow and SendMessage to closed the window is directly done BUT in c++ builder it does not cooperate.

Any ideas, suggestions, code?

You are type-casting a narrow char[] literal to a wide wchar_t*
pointer. You can't do that. To specify a wide string literal, you
need to use the 'L' prefix instead:

MyHandle = FindWindow(L"Properties",NULL);

HWND Find = ::FindWindowEx(0, 0, (wchar_t*)"Properties", 0);

Same here, too:

HWND Find = ::FindWindowEx(0, 0, L"Properties", 0);

Either way, make sure the functions are not returning NULL before you
call SendMessage().

this code execute it,
HWND MyHandle;
MyHandle = FindWindow(NULL,L"Properties");
if (MyHandle!=0) SendMessage(MyHandle, WM_CLOSE, 0, 0);
