I want to find the windowhandle of a dialog application minimized to the system tray.
enumwindow does not find the window, since the window is not visible.

what should I do?

gtz,

u can use spy++ from visual studio tools to find any window handle. even minimized. if u know class and caption.

for example. i'be minimized icq. so it doesnot enumarated. but i can c it in this tool.

how to do it programatically. i think use FindWindow with known class and caption

The window is not minimized to the taskbar but to the systemtray. enumwindows finds minized windows to the taskbar but not when they are minimized to the tray.

I use enumwindows instead of findwindow since it is more stable. I guess both functions do the same thing.

yes, spy++ does find my window. How does spy++ finds its windows?

systemtray, taskbar - its not a big reason. in both cases main windows are hided.
i won't dispute about stability, but as i said: use findwindow to get handle.
u've caption and u've class, or u dont've? its quite complete info to use this function.

or i dont understand your question.

Yes, i have the caption.
with enumwindows:
- I find the window when its visible on screen.
- I don't find the window when it is minimized to the tray.
it is simply not listed when using the callback func.

I guess you don't understand the problem.
thank you for your help anyway

p.s.
// i had outlook in system tray.
HWND hwndOutlook = ::FindWindow(NULL, "Inbox - Microsoft Outlook");
// i got valid handle for this window.

Using spy++ and find a class of the program. This is safer in my view, 'coz the caption may be changed by a program behaviour or other program.

HWND hWindows = FindWindow("ProgClass", NULL)

I think you are still confused between a minimized window and a hidden window.

Of course, because it was minimized, not hidden.

ok. lets determine what window should call hidden and what should be call minimized? it looks like demagogy but as i see its necessary.
i want to hear your oppinion!

EnumWindows() will enumerate all top-level windows on the screen, while EnumDesktopWindows() will enumerate all top-level windows on a desktop.

...AND...If the system Tray OWNS the minimized window, then you can get the window handle of the system tray and try to enumerate the child windows of it.
One of them is probably the window you want.

Do this:
messagemap:
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNotify)

in .h file:
afx_msg BOOL OnToolTipNotify(UINT id, NMHDR *pNMHDR,LRESULT *pResult);

function implementation something like this:

BOOL PbmFlexListViewer::OnToolTipNotify(UINT id, NMHDR *pNMHDR, LRESULT *pResult){<br />
	//pTTT->szText ==> maximum 80 characters<br />
	CString tooltiptext2display;<br />
	tooltiptext2display = "";<br />
	TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;    <br />
	UINT nID = pNMHDR->idFrom;<br />
    if(pTTT->uFlags & TTF_IDISHWND){<br />
        //idFrom is actually the HWND of the tool<br />
        nID = ::GetDlgCtrlID((HWND)nID);<br />
		switch(nID){<br />
			case IDC_PBM_DOWN:		tooltiptext2display.Format(IDS_MOVE_ROW_DOWN_PBM);<br />
			break;<br />
			case IDC_PBM_UP:		tooltiptext2display.Format(IDS_MOVE_ROW_UP_PBM);<br />
			break;<br />
			case IDC_FLEX_NEW_ITEM:	tooltiptext2display.Format(IDS_ADD_NEW_ITEM);<br />
			break;<br />
			case IDC_BUTTON_PRINT:	tooltiptext2display.Format(IDS_PBM_FLEXLIST_PRINT);<br />
			break;<br />
			case IDC_STATIC_ROW_COL:tooltiptext2display.Format(IDS_TOOLTIP_FLEXLIST_STATICCURRENTCELL);<br />
			break;<br />
			default:				tooltiptext2display = "";<br />
			break;<br />
		}								//end switch<br />
		strcpy(pTTT->szText, tooltiptext2display);<br />
		return(TRUE);<br />
	}									//end if<br />
	else{ return FALSE; }				//end else<br />
}										//end function OnToolTipNotify

DON'T FORGET in OnInitDialog or constructor:
EnableToolTips(true);

good luck.

Add a CTooltipCtrl[^] to your dialog/view class and add the button to it.

Question about WTS fucntions

4apai20-Aug-04 1:01

20-Aug-04 1:01

hallo.
i need your help.
i want to list sessions on a remote terminal server. i use next code:

HANDLE hServer = WTSOpenServer("WMWareComputer");
// hServer is set to NULL;
DWORD dwError = GetLastError();
// dwError is set to 5 (Access Denied)

As i undersatnd i've insufficient access rights on a remote computer.
in documentation i find that i need to have QUERY_INFORMATION access rights to view this specific information.
How can i change access rights?

in the next case i get following results:

HANDLE hServer = WTSOpenServer("RemoteComputer");
// hServer is initialized with a real value, smth like 0x04548343;
DWORD dwError = GetLastError();
// dwError is set to 0 (all is ok)
BOOL bRet = WTSEnumerateSessions(hServer, 0, 1, &wtsSessionInfo, &dwCount);
// bRet is true. all is ok.
// But dwCount is 0. but i know for sure that there're some sessions.

and one more. when i execute those code on specified machines directly, they return good results.
what do i do wrang?

waiting for your ideas, discussions...

its me again
i found where can i set user access rights on terminal server. and set full control for everyone. but still've the same problem.
what can be wrong?

Blake Miller20-Aug-04 4:42

What did GetLastError() return from the WTSEnumerateSessions() and did WTSEnumerateSessions() return a non-zero value?

4apai20-Aug-04 5:43

20-Aug-04 5:43

after enumaratesessions :
GetLastError return 0.
and the result is true (non-zero);
all is ok. looks like it must be so. but it it shioldn't.

I am sorry I do not know more about your specific problem.
I was trying to help you rule out obvious mistakes, and I only ever enumerated sessions on the local server.
