Hello. In Windows7-Aero, the malfunction such as the following video does not occur.
http://ifreeta.dee.cc/20100922/Untitled25.html But , On the Basic themes, the following malfunction occurs.
http://ifreeta.dee.cc/20100922/Untitled25.html
The re-drawing of the screen of RibbonMenu is not performed definitely.
The programs are as follows. // ----------------------------------------------------------------------------
/**
*/
// ----------------------------------------------------------------------------
void ProcessCtl( CString csCommand )
{
DWORD dwThread = 0; BOOL result;
DWORD dwExitCode;
STARTUPINFO si;
PROCESS_INFORMATION pi; ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(STARTUPINFO);
si.lpReserved = NULL;
si.dwX = CW_USEDEFAULT;
si.dwY = CW_USEDEFAULT;
si.dwXSize = CW_USEDEFAULT;
si.dwYSize = CW_USEDEFAULT;
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOWNORMAL;
ZeroMemory( &pi, sizeof(pi) ); result = CreateProcess( NULL, csCommand.GetBuffer( csCommand.GetLength() ), NULL, NULL, FALSE,
DETACHED_PROCESS | HIGH_PRIORITY_CLASS,
NULL, NULL, &si, &pi ); DWORD dRet = WaitForSingleObject( pi.hProcess, INFINITE ); if( dRet != WAIT_FAILED )
{
GetExitCodeProcess( pi.hProcess, &dwExitCode );
} CloseHandle( pi.hProcess );
if( dwExitCode >= 0 ){
if( (dwExitCode / 10) == 1 ){
ProcessCtl( csCommand );
}
}
}
BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{ if( nID == ID_EDIT_PASTE && nCode == CN_COMMAND && pExtra == NULL )
{
ProcessCtl("NotePad.exe");
return TRUE;
}

Hello. I tried this source code.
However, re-drawing does not work at the time of specific pattern definitely. http://ifreeta.dee.cc/20100927/Untitled27.html Without its starting from VisualStudio , When I started direct Exe, a bug occurs. //起動
result = CreateProcess(
NULL, csCommand.GetBuffer( csCommand.GetLength() ), NULL, NULL, FALSE,
DETACHED_PROCESS ,
NULL, NULL, &si, &pi ); //DWORD dRet = WaitForSingleObject( pi.hProcess, INFINITE ); DWORD dRet = WaitForSingleObject( pi.hProcess , 10 );
for( ; dRet == WAIT_TIMEOUT; dRet = WaitForSingleObject( pi.hProcess , 10 ) ){
CExtPaintManager::stat_PassPaintMessages();
}

Redrawing stops working when the message queue is overloaded with messages. The CExtPaintManager::stat_PassPaintMessages() static method handles only painting messages. So, please try the next version:
result =
CreateProcess(
NULL,
csCommand.GetBuffer( csCommand.GetLength() ),
NULL,
NULL,
FALSE,
DETACHED_PROCESS ,
NULL,
NULL,
&si,
&pi
);
HWND hWndMain = ::AfxGetMainWnd()->GetSafeHwnd();
DWORD dRet = WaitForSingleObject( pi.hProcess , 10 );
for( ; dRet == WAIT_TIMEOUT; dRet = WaitForSingleObject( pi.hProcess , 10 ) )
{
if( hWndMain == NULL || ( ! ::IsWindow( hWndMain ) ) )
return;
CExtPopupMenuWnd::PassMsgLoop( true );
}

The following line of code is bad because it switches the main UI thread of the application into the non-responding and non-draw-able state:
DWORD dRet = WaitForSingleObject( pi.hProcess, INFINITE );
Please replace this bad line of code with the following: DWORD dRet = WaitForSingleObject( pi.hProcess, 10 );
for( ; dwRet == WAIT_TIMEOUT; dRet = WaitForSingleObject( pi.hProcess, 10 ); )
CExtPaintManager::stat_PassPaintMessages();
The main frame window will be able to repaint itself, but the UI will not be click-able. I.e. main frame will behave like disabled. Is that what you need?
