I believe you need to pass the HMODULE for the dll, not the exe, which is what GetModuleHandle(NULL) returns. Use something like GetModuleHandle("nameofdll.dll").

yes, thank you very much it has resolved!
i thought since the function resides inside dll it will get the handle of the dll. i spent a few days troubleshooting this problem, thank you very much!

Hi all,
I have to create a win 32 dll which is loaded by two different processes. MSDN tells me that the dll is mapped to the process space of the calling exe and so there would be two instances of the dll running. The problem is that the dll which I have to create keeps doing some processing on a hardware board. Does it mean that both instances of my dll will keep on doing these operations parallely on the board? If this is the case then I need to make sure only one instance of the dll runs on the system, no matter how many processes load it. Any pointers in this direction and how to create a single shared instance of dll will be very helpful.

We see the very common MFC as shared dll option in our projects. Does this option mean than only one instance of the MFC dll would be running on the system? What happens behind when create a MFC shared dll?Can I use the same technique to create a shared dll?
Thanks in advance. Your responses are truly appreciated..

Yes there be only one Instance loaded in memory, and every function has it address, using which we can make the call to the function!.
misha_grewal wrote: What happens behind when create a MFC shared dll
there is lot of difference between shared MFC DLL and Dll you are creating... actually your problem is syncronization not sharing... actually here Shared mean that Application will use MFC dll previously loaded OS.. and BTW I believe MFC dll itself use Syncronization technique like Mutex,events etc

I use LoadLibrary( "ntdll.dll" ) to hide process!
just like :
hNtDLL = LoadLibrary( "ntdll.dll" );
RtlInitUnicodeString =
(CProcessHide::RTLINITUNICODESTRING)GetProcAddress( hNtDLL, "RtlInitUnicodeString");
ZwOpenSection = (CProcessHide::ZWOPENSECTION)GetProcAddress( hNtDLL, "ZwOpenSection");
.............
but in window 2000 pro :
1,some compuctors can start up and hide process;
2,some compuctors can start up but can't hide process;
3,some compuctors can't start up the exe. Show Error like this: "now Creating Error Log!"
if I Setup vc6.0 in the compuctors which can't Start up the exe.
the exe can Start up ,and Hide process!
why?
how to fix it ?
thanks

Hi,
A simple way. Make m_wndStatusBar public in CMainFrame class.
Include "MainFrm.h" in YourView.cpp and/or YourDoc.cpp.
Type the following to change the text of the pane at 0 index:
<br />
CMainFrame *pFrame = (CMainFrame *) AfxGetMainWnd();<br />
pFrame->m_wndStatusBar.SetPaneText(0, "New Text");
If you want more flexibility, you need to change/or manipulate also with
a static array 'indicators' in MainFrm.h file, which sets the panes in the status bar.

Could somebody have a such kind of sample code.
I would like to implement it as downloading a video file from the HTTP Server,
and when you are downloading you wouldn't wait for completing it; instead, you
could watch it during downloading processing.
If someone could give me a sample code, or some reference websites.
Appreciate more, and thanks a million.

I want to create a window using a dialog template without use DialogBox function. Is it possible? I'm not creating a MFC application.
I want to do it because I don't want to use 2 functions to control my application like WndProc and MyWindow function to receive the messages.

Every windows app must have a WndProc function.

SetDlgItemText(m_hWnd, nID, ...
SetDlgItemText(GetSafeHwnd(), nID, ...
SetDlgItemText(*this, nID, ...
SetDlgItemText(nID, ...
The last one is CDialog's (actually CWnd's) wrapper for SetDlgItemText.

Hmm? None worked... 
SetDlgItemText(m_hWnd, nID, ...
m_hWnd doesn't exist...
SetDlgItemText(GetSafeHwnd(), nID, ...
GetSafeHwnd() neither... I looked it up and it came out to be a member of CWnd, but it's not static... 
SetDlgItemText(*this, nID, ...
error C2664: 'SetDlgItemTextA' : cannot convert parameter 1 from 'CMazzeeMapGrouperApp' to 'HWND'
SetDlgItemText(nID, ...
Doesn't exist either... 
Do you know of another way? Thanks!

I have an app which always runs in the background (main window is hidden) and it's only visible cue to the user is an animated icon on the task bar. The icon is animated when the app is actively polling for information, and static when the app is running but no polling is taking place. Now according to the task manager my app is running the CPU at about 20% just to animate the icon. This is not so bad when the user is sitting at the computer but the app is designed to run 24/7 so I would really like to be able to stop the animated icon when the user is not there to see it (screen saver starting and or monitor turning off) and start it again when the user is there (screen saver stops and/or monitor turns on).
Is there a way to detect the screen saver starting and stopping or the monitor turning off and on from an app that is not the currently active app? WM_SYSCOMMAND with SC_SCREENSAVE is only recognized by the active app when the screen saver starts, not when it stops.
