I belive you are talking abut shell extension, Micheal Dunn has few articles on what you are looking for.

No, I don't want to write a shell extension, I just hope to find a way to reuse this menu (without turning the file name into a PIDL and then playing explorer - I roughly know the protocol how this menu is created  )
But you're right, I should have thought of Michaels articles, I'll check them....

Can somebody please explain what I have to do in order to have CButton controls on dialog respond to WM_CHAR messages (and not to use PreTranslateMessage() ). I tried to put OnChar() in my instance of CDialog with classWizard but the dialog just beeps when I press keys.

Are you talking about shortcut keys ? did ya try putting '&' before one of the char in the dialog button text ?

Did you try it by subclassing cbutton.....you should derive your own class(CMyButton) from CButton and use CMyButton on your dialog box instead of CButton and then add the messagemap for WM_CHAR ...it will work...

When you detect a second instance is being launched, why not call ShowWindow(SW_RESTORE)?

Wait... so the 1st instance should control how many instances should run and not the 2nd one? Right now, I'm using CWinApp::InitInstance to check if an instance is already running. If so, I don't create the dialog and return FALSE so that instance exits.

You cud try some IPC mechanism (mutex, event etc) to communicate between the 1st and 2nd instance. When the 2nd instance comes up it cud for e.g set an event in the 1st instance to signal it to show itself.

yes, it will work to determine that another instance is running, but how will you use to restore the window ???

I had used this technique long back...
Registered a windows message. when another instnce is found then broadcast the message.
Handle the event and post showwindow to your main window.

Well I managed to find a solution. In OnInitDialog(), I just save the m_hWnd value to the registry and use that value with WM_SHOWWINDOW if needed. The only drawback is that even though the dialog window appears, it hasn't set focus and the taskbar isn't refreshing. I have to click on the dialog window to activate it and make it visible in the taskbar. I tried WM_ACTIVATE but with no success...

CWindow::BringWindowToTop<br />
BOOL BringWindowToTop( );
Remarks
Brings the window to the top of the Z order.
Does this helps???

No  The thing is that it will work once (with or w/o BringWindowToTop( )) but after that the dialog will always be at the bottom of the z-order and wont be displayed in the taskbar...

very stupid, will lead to lot of bugs in the long run. 
The method that told you about registering the window will surely work.
While using FindWindow did you give the classname or the windowtitle.
I think i have used classname to find the window and it worked greate.

I cannot find a solution anywhere.
Pleae help.

search for the class RichEditCtrlGS on codeproject.
I found the solution to this problem there last week.
It gives you all the information you need.
if you do not find it i will send it to you.

Hi,
I have an application that is hidding in the tray. Currently, I'm able to detect how many instances of my app are running so I can prevent that more than one is. What I'd like to do is that if a 2nd instance is launched, it would bring the main dialog up from the 1st instance.
FindWindow will not work since the dialog is not visible while the app is hiding in the tray. Is there some trick to find a hidden window, or perhaps I could manage to find the tray icon's menu and trigger a message?
Thanks!

Is there a way to find out if two paths/volumes are on the same physical drive?
I want to know if C: / D: are on the same disk.

I am trying to clear/delete the AutoComplete data (like Internet Explorer's "Clear Forms" and "Clear Passwords" options)
I believe AutoComplete data is stored in the registry under hidden keys.
How do you determine which registry keys need to be deleted?
Can you just delete them or are they protected?
I use C with the Win32 API.
Thanks,
Richard

Check out this key.

Which simply turns auto-complete on or off. It does not actually clear the entries.

I would say download from http://www.sysinternals.com/ntw2k/source/regmon.shtml Regmon and check what IE does when you clear the forms
