Hi Dale,

I am using the MFC Feature Pack Sample [^]located at:

\Samples\1033\Visual C++ 2008 Feature Pack\RibbonMDI

I pasted the code snippets you have shown into the InitRibbon() function. It compiles cleanly after I added resource definitions. The items only show once for me. I am not able to reproduce the issue you have described.

Thx, for looking into this, here is image I see in XP:

http://img260.imageshack.us/img260/2356/peephelp.jpg[^]

I used the MDIRibbon InitRibbon and added the following:

to resource.h

#define ID_HELP2 33016
#define ID_HELP_SHOWHELPONSTARTUP 33017

to mainfrm.cpp just after pPanelWindow->Add (pBtnWindows);

CMFCRibbonButton* pBtnHelp = new CMFCRibbonButton (ID_HELP, _T("&Help"), 10, 11);
pBtnHelp->SetKeys(_T("H"));
pBtnHelp->AddSubItem(new CMFCRibbonLabel(_T("Help")));

CMFCRibbonButton* pBtnPeepHelp = new CMFCRibbonButton(ID_HELP2, _T("Peep &Help"), 10, 11, TRUE);
pBtnPeepHelp->SetToolTipText(_T("Peep Help"));
pBtnPeepHelp->SetDescription(_T("Get help using Peep."));
pBtnHelp->AddSubItem(pBtnPeepHelp);

CMFCRibbonButton* pBtnShowHelp = new CMFCRibbonCheckBox(ID_HELP_SHOWHELPONSTARTUP, _T("Show Help &On Startup"));
pBtnShowHelp->SetToolTipText(_T("Show Help On Startup"));
pBtnShowHelp->SetDescription(_T("Show Help file when starting Peep."));

Hi Dale,

I have confirmed the behavior you are describing. I am now getting the same results. I do not know if this behavior is by design.

However do you really need the "Peep &Help" to have a menu handler? If you give this menu item an ID of zero it will be ommitted from the customization dialog.

Increase mainframe window if right side of inserted view is out of MainFrames client area [modified]

I have some problems getting the screen coordinates of the client area of my mainframe and later increasing if the right side coordinate of the mainframes client Rect is smaller than the views right side coordinate.
For testing i positioned the view fitting in the mainframes client area(By Mouse). So the outside coordintes of the View Window should be the same as the inside coordinates of the main frame client area.
But it isn't!!
What am I doing wrong?

Code inside the view class:

GetWindowRect(ViewWindo wRectSC);

pMainFrame->GetClientRect(MainFrameClientRectCCMain);
MainFrameClientRectSC=MainFrameClientRectCCMain;
pMainFrame->ClientToScreen(MainFrameClientRectSC);
But
ViewWindowRectSC.right is not MainFrameClientRectSC.right

f.e.
ViewWindowRectSC: {top=99 bottom=918 left=14 right=1267}
MainFrameClientRectSC {top=42 bottom=964 left=4 right=1277}

I tried a lot but it is getting more and more unclear.

For example i tried to find frames or bars or something else with the GetSystemMetrics() function because i was thinking that there could be coordinate values not bringing these into account these. Didn't help.

Also tried to calculate the outside of the view window by first using
GetClientRect(ViewClientRectCC) and then
AdjustWindowRectEx(ViewClientRectCC,GetStyle(),1,GetExStyle());
Didn't help.
Thanks a lot

If your view is going to be bigger than the frame size, you must ideally use CScrollView so that the view is scrollable and you can also use CScrollView::ResizeParentToFit[^] to resize the frame to the size of the view.

Thanks for your answer.

I just reduced the problem to the described upstract conditions. In real i am setting views to before stored positions when i rebuild the application or the user opens a config file. The user is able to load a defined graphview which has coordinates which sometimes d'ont fit into the frame. (If the frame was smaller during constructing of the graphviews)
The use of scrollviews would be possible but i wouldn't like to have scrollbars. I constructed tabs in this view and in each tab there are one or more graphs. But there are also more then one view in the mainframe. The user has to positioned them once and he and others can open these configuration from file.
How does CScrollView::ResizeParentToFit increase the Mainframe? Just at the view coordinates which are bigger then the accordant one of the MainFrame?

My own answer to my own question. A little stupid but maybe someone can use my solution to save some times and delivers new idears.

I solved my problem as follows:
First i used the sysinternals freeware zoom tool (http://technet.microsoft.com/de-de/sysinternals/bb897434%28en-us%29.aspx[^])to find the sizes of frames and borders.
Then the second tool the winspector tool from gipsysoft (http://www.windows-spy.com/[^] )to find out coordinates and classes of the interesting frames.

With this informations i was looking for parent() parent()....... frames and windows until i found the windows and frames with the correct coordinates.

The resulting code as follows:

CRect MainFrameClientRect,MainFrameClientRectSC,ViewsFrameWindowRect,PPWindowRectSC;
CWnd* PP;
//ClientRect  of mainframe 
PP=GetParent()->GetParent();
PP->GetClientRect(MainFrameClientRect);
MainFrameClientRectSC=MainFrameClientRect;
PP->ClientToScreen(MainFrameClientRectSC);

//View covering outside frame
GetParentFrame()->GetWindowRect(ViewsFrameWindowRect);

CMainFrame* pMainFrame=(CMainFrame* )theApp.GetMainWnd();
WINDOWPLACEMENT MainFramePlacement;
MainFramePlacement.length = sizeof(WINDOWPLACEMENT);

//Get the Mainframes actual position
::GetWindowPlacement(pMainFrame->m_hWnd,&MainFramePlacement);

//if views right/bottom edge is outside mainframes client area increase MainFramePlacement right/bottom
// coordinates so view windows right/bottom  will be next to mainframes client area right/bottom 
 
if(ViewsFrameWindowRect.right>MainFrameClientRectSC.right)
MainFramePlacement.rcNormalPosition.right+=ViewsFrameWindowRect.right-MainFrameClientRectSC.right;
if(ViewsFrameWindowRect.bottom>MainFrameClientRectSC.bottom)
MainFramePlacement.rcNormalPosition.bottom+=ViewsFrameWindowRect.bottom-MainFrameClientRectSC.bottom;

//increase and position mainframe
pMainFrame->SetWindowPos(NULL,
												 MainFramePlacement.rcNormalPosition.left,
												 MainFramePlacement.rcNormalPosition.top,
												 MainFramePlacement.rcNormalPosition.right-MainFramePlacement.rcNormalPosition.left,
												 MainFramePlacement.rcNormalPosition.bottom-MainFramePlacement.rcNormalPosition.top,
												 SWP_NOZORDER);
pMainFrame->ShowWindow(theApp.m_nCmdShow);
pMainFrame->UpdateWindow();

Thanks to all which were looking at my question and thinking about a solution but couldn't help.

how to use createprocess to create a new console window(cmd.exe) and run commands

Hi,

I am trying to develop a console application, in which i am creating a new process (executable is c:\windows\system32\cmd.exe).

I am able to see the newly created process cmd.exe (console windows). but how can i execute some commands in the newly created console window programatically?

if( !CreateProcess("C:\\windows\\system32\\cmd.exe",
NULL, // Command line.
NULL, // Process handle not inheritable.
NULL, // Thread handle not inheritable.
FALSE, // Set handle inheritance to FALSE.
CREATE_NEW_CONSOLE, // No creation flags.
NULL, // Use parent's environment block.
NULL, // Use parent's starting directory.
&si, // Pointer to STARTUPINFO structure.
&pi ) // Pointer to PROCESS_INFORMATION structure.
)
{
printf( "CreateProcess failed (%d).\n", GetLastError() );
return;
}

The second parameter in the CreateProcess Function[^] is the commandline. You can pass your arguments there such as the path to a batch file. This is probably what your looking for.

If you are looking to do some advanced interaction with the console then it would be possible to overide the hStdInput handle of the STARTUPINFO Structure[^] with a handle to a named pipe or something.

Hi David,

I think the second argument is the command line argument to the process that we are creating. i want to execute a command after creating the cmd.exe process.

for example, how can i execute a "DIR" command once i create a cmd.exe process? can i use WriteConsole() to execute the command?

Thanks in advance...

You mean like:

CreateProcess(NULL, "cmd.exe /c dir", NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);

Using Randor's second suggestion will also work but is more involved.

Hi Devgo,

devgo wrote:

The WriteConsole Function[^] is designed for writing to the console screen buffer. This is probably not what you are looking for.

What you are looking to do is called redirected console input/output. When a console process is created the NT kernel automatically creates a few standard I/O handles. The GetStdHandle Function[^] and SetStdHandle Function[^] can be used to access these standard handles. The CreateProcess Function[^] allows you to pass a STARTUPINFO Structure[^] which gives you an opportunity to access these standard I/O handles. You can replace these handles with your own.

Here is an example of redirected console input/output.

Hi Dev.

I suggest that you research and seek to understand STDIN STDOUT STDERR[^] because when you open a command prompt and you type DIR you are actually writing to the STDIN stream. After you research these streams you will have a better understanding of my answer.

devgo wrote:

You have been given several options.

Option 1.) Pass a command on the CreateProcess command line.

>cmd /?
/C      Carries out the command specified by string and then terminates
/K      Carries out the command specified by string but remains

Option 2.) Interact with the standard input handle and pass commands.

How to spawn console processes with redirected standard handles[^]

These are your best options if you are using CreateProcess to open the command prompt as you described in your original post.

Here is another Microsoft sample of redirecting the input/output handles.

As you were aware, i am trying to execute a command in the console window created through createprocess(); now i am trying to execute the command by using Pipes as you suggested.

Hi Devgo,

In the future you should not reply to yourself. You are lucky that I review my old threads... I did not get notification of your response because you replied to yourself. Anyway I wrote a quick and dirty sample for you. In this example I am creating an instance of CMD.EXE and writind the Dir command to its STDIN pipe. I then use MessageBox to show the results.

C++

#include "stdafx.h"
#include <windows.h> 
#include <tchar.h>
#include <stdio.h>
#include <process.h>

#pragma comment(lib,"user32.lib")

HANDLE g_hChildStd_IN_Rd = NULL;
HANDLE g_hChildStd_IN_Wr = NULL;
HANDLE g_hChildStd_OUT_Rd = NULL;
HANDLE g_hChildStd_OUT_Wr = NULL;

unsigned __stdcall ReadCMDThread(void* pArguments)
{
	DWORD dwAvailable =0;
	DWORD bytesRead =0;
	CHAR szOut[4096] = {0};
	while(0 == bytesRead)
	{
		PeekNamedPipe(g_hChildStd_OUT_Rd,szOut,sizeof(szOut),&bytesRead,&dwAvailable,NULL);
		if(0 != bytesRead)
		{
			Sleep(1000);
			ReadFile(g_hChildStd_OUT_Rd,szOut,sizeof(szOut),&bytesRead,NULL);
			::MessageBoxA(NULL,szOut,"",MB_OK);
			break;
		}
	}
	return 0;
}

int _tmain(int argc, _TCHAR* argv[])
{
	DWORD bytesRead;
	DWORD exitcode;
	PROCESS_INFORMATION pi;
	STARTUPINFO si;
	SECURITY_ATTRIBUTES sa;

	ZeroMemory(&sa,sizeof(sa));
	sa.nLength=sizeof(SECURITY_ATTRIBUTES);
	sa.bInheritHandle=TRUE;

	CreatePipe(&g_hChildStd_IN_Rd,&g_hChildStd_IN_Wr,&sa,0);
	CreatePipe(&g_hChildStd_OUT_Rd,&g_hChildStd_OUT_Wr,&sa,0);

	ZeroMemory(&si,sizeof(si));
	GetStartupInfo(&si);

	si.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
	si.hStdOutput = g_hChildStd_OUT_Wr;
	si.hStdError = g_hChildStd_OUT_Wr;
	si.hStdInput = g_hChildStd_IN_Rd;
	si.wShowWindow = SW_HIDE;
	
	BOOL bSuccess = CreateProcess(
		_T("C:\\windows\\system32\\cmd.exe"),
		NULL,
		NULL,
		NULL,
		TRUE,
		CREATE_NEW_CONSOLE,
		NULL,
		NULL,
		&si,
		&pi);

	UINT threadID;
	HANDLE hThread = (HANDLE)_beginthreadex(NULL,0,&ReadCMDThread,NULL,0,&threadID);
	
	Sleep(500);

	if(INVALID_HANDLE_VALUE != hThread)
	{
		DWORD dwWritten = 0;
		CHAR szIN[4096];

		strcpy(szIN,"dir\n");
		WriteFile(g_hChildStd_IN_Wr,szIN,strlen(szIN),&dwWritten,NULL);
		
		WaitForSingleObject(hThread,INFINITE);
		CloseHandle(hThread);

		strcpy(szIN,"exit\n");
		WriteFile(g_hChildStd_IN_Wr,szIN,strlen(szIN),&dwWritten,NULL);
	}

	CloseHandle(g_hChildStd_IN_Rd);
	CloseHandle(g_hChildStd_IN_Wr);
	CloseHandle(g_hChildStd_OUT_Rd);
	CloseHandle(g_hChildStd_OUT_Wr);
	return 0;
}

The code is ugly and contains some Sleeps to allow CMD.EXE to initialize. I also use Sleep to wait for the Read pipe to become full. There are probably better ways to do this. Also... on my Windows7 workstation I had problems terminating CMD.exe by closing its handles. Using TerminateProcess is generally not desirable so I opted to write exit to the STDIN stream.

There are some other functions that you might want to get familiar with:

GenerateConsoleCtrlEvent Function[^]

when you register an ActiveX object, its CLSID is added to HKEY_CLASSES_ROOT/CLSID and a path to the DLL is added below that. so if the debug and release versions use the same CLSIDs for their interfaces (which they typically do), there's no way to have multiple versions, regardless of where the DLLs live.

Hi. Well.. I need to add some tooltips to my main window (CDialog).
So... I do this in OnInit

bool test21=TTC.Create(this); //creating tooltipwindow
theApp.tooltip=&(TTC);
m_but.MoveWindow(0,0,500,500);
bool test11=theApp.tooltip->AddTool(m_but,"Cool?");
TTC.Activate(TRUE);

and

BOOL MainDial::PreTranslateMessage(MSG* pMsg)
{
	if (NULL != theApp.tooltip)            
		theApp.tooltip->RelayEvent(pMsg);
	return CDialog::PreTranslateMessage(pMsg);
}

Appears a great button, but hint doesn't. Why? Any idea? Smthng that i'am missing? Huh?

Could it be that in your OnInitDialog the TTC variable, which is i assume a CToolTipCtrl a local variable? If so then when your OnInitDialog is done and returns, TTC will be deleted and its destructor also destroys the tooltip. Of course that you don't get a crash in PreTranslateMessage suggests this is not the case but it might happen. Try making your TTC a member of the dialog class if it is not and use that instance instead of storing a pointer at it.

this->SetParent(pParentWnd);

but once again it doesn't help. Hint doesn't appear. Any idea?
