Why do you want the path?
Is it so that you can use it to launch a PDF file?
If so, you don't need to know the path.
You can simply use ShellExecute to launch it.

It's not because of my post Mr. Crow. Smile | :)

I've gave him this answer after I saw his post about the exe path.
I knew that you will give him the right directions about the exe path and decided to show the OP how could he pass cmd line args to Acrobat reader in order to select given page. Smile | :)

Hi deadlyabbas,

Did you try searching the Adobe forums[^] before asking in the C++ forum?

Try

SearchPath[^]

Pass "AcroRd32.exe" as lpFileName to that function.

I am trying to widen drop-down part of combo box but keep fixed size of combo box.
For the same i used following in my code. But drop down portion of the combo box remained as it is.
No change reflected in it's size.

LRESULT OnDropDown(WORD wNCode, WORD wID, HWND hWCtl, BOOL & bH1)
{ 
   ::SendMessage(v_ComboBox->v_hWnd, CB_SETDROPPEDWIDTH,      100 , 0);
   ::SendMessage(v_ComboBox->v_hWnd, CB_SETHORIZONTALEXTENT , 100 , 0);
}

Please help to solve this issue..

CB_SETDROPPEDWIDTH is used to set the maximum allowable width and not the exact width of the drop down list.
In your case the drop down list will grow up to 100 pixel if you have lengthy strings as its items.

For fixing a large width to the drop down, you may need an owner draw combo box.
This article could be of help - FontComboBox - a font listing combo box for .NET[^]

I guess thats not correct. To confirm I just tried the code and the width of drop down changed to 100( Provided the width of combo is less than 100 pix ).

Thanks to all for quick response.
Now my problem is solved.
MSDN itself states "Call this function to set the minimum allowable width, in pixels, of the list box of a combo box"
The problem was the very small width specified by me.
The 100 pixel size was less then the width of the combo box itself, that's why i was not able to see any change.

Thank you very much!

Stopping windows shutdown in C++./MFC?

Kushagra Tiwari16-Sep-09 22:50

16-Sep-09 22:50

Hello all
I am making a MFC silent application which will trace if windows is shutting down or not and if it is I will have to stp this shut down and perform some other work and then initiate the shutdown myself.I am overriding method to handle WM_QUERYENDSESSION . the code is some thing like this

BOOL CMyShutDownDlg::OnQueryEndSession()
{

ShellExecuteA(NULL, "open","abc.exe", NULL, NULL, SW_SHOWNORMAL);
::MessageBox(NULL,_T("Test"),_T("I stopped shutdown"),MB_OK);
return FALSE;
}

The thing is that returning false allows window to halt the sutdown but not completely stop it. Also,while trying to file any other exe at this time leads to'windows error' stating that windows cannot execute this as it is about to shutdown. I think as soon as windows recieves WM_QUERYSHUTDOWN it sends all other applications WM_CLOSE which is what I think is stopping my aplication to execute any other application from itself.

Please help me in this .

Regards,
Kushagra

The documentation for WM_QUERYENDSESSION says that the WM_ENDSESSION message is sent after the former message is processed. You could try ShellExecute in the WM_ENDSESSION handler.

The documentation also says that after 5 seconds the system displays information about the applications that are blocking shutdown so that the user can manually end the application. So I don't think you have much time here.

It's probably a good idea to review the requirements or design and look for alternatives.

Have you seen the AbortSystemShutdown Function[^] and the ShutdownBlockReasonCreate Function[^]?

Here is an example of using AbortSystemShutdown[^].

How about:

CMyShutDownDlg::OnQueryEndSession()
{
    PostMessage(MY_MESSAGE);
    return FALSE;
}
  
CMyShutDownDlg::MyMessageHandler()
{
    ShellExecuteA(NULL, "open","abc.exe", NULL, NULL, SW_SHOWNORMAL);
}

You might also consider using TRACE() instead of MessageBox() for such debugging.

Maybe, but you're testing will be the ultimate judge of that. Don't discount Superman's "respond to WM_QUERYENDSESSION rather than WM_ENDSESSION" suggestion.

Kushagra Tiwari17-Sep-09 20:24

17-Sep-09 20:24

Also ..If I want to distinguish betwwen a Shutdown event and a Restart event , what should be done in achieving the same ? As , WM_QUERYENDSESSION doesnot give me any differentiation between Shutdown and Restart. Is there a way to know specifically which one of the two has been initiated ??
