C++ Builderから別ソフトを操作するための方法。

試しにnotepadを表示して、[表示(V)]->[ステータスバー(S)]を実行してみる。

参考1: http://www.gesource.jp/weblog/?p=5143

sample.cpp
void __fastcall TForm1::Button1Click(TObject *Sender)
{

	STARTUPINFO si = {};
	si.cb = sizeof(si);
	PROCESS_INFORMATION pi = {};

	CreateProcess(NULL, L"notepad.exe", NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);

	WaitForInputIdle(pi.hProcess, INFINITE);
	CloseHandle(pi.hThread);
	CloseHandle(pi.hProcess);

	HWND hwnd = GetDesktopWindow();
	hwnd = FindWindowEx(hwnd, NULL, L"Notepad", NULL);

	SetForegroundWindow(hwnd);

	for(int loop=0; loop<3; loop++) {
		Sleep(3000);
		keybd_event(VK_MENU, 0, 0, 0); // Altキー
		keybd_event('V', 0, 0, 0);
		keybd_event('S', 0, 0, 0);
		keybd_event(VK_MENU, 0, KEYEVENTF_KEYUP, 0); // これがないとAltを押したままになる
	}

	keybd_event(VK_RETURN, 0, 0, 0);

}

KEYEVENTF_KEYUPは大切。これがないとAltが押しっぱなしになり、何度かやってしまって、不自由になり、Windowsをログアウトした。
