I created a exe named as test.exe.I want to put a log whether the exe is closed manually or by some other crash. If the exe gets crashed,will it call onclose function or how that exe will get closed?
How can i put a log during crash?

Thanks,

You cannot log the crash (of course OnClose isn't called when the application crashes). Anyway you may log the normal program execution in order to have hints about the crash.

Thanks. Then how that exe will get closed during crash? Whether it will call OnClose or OnDestroy function?

You should call SetUnhandledExceptionFilter[^] to set a filter function to be called during a crash.

Suppose if i closed the application using task manager, the control is not coming to SetUnhandledExceptionFilter function.

Did you read the docs for that function:

After calling this function, if an exception occurs in a process that is not being debugged, and the exception makes it to the unhandled exception filter, that filter will call the exception filter function specified by the lpTopLevelExceptionFilter parameter.

As Task Manager likely uses something akin to TerminateProcess(), it's doubtful that both of the above conditions would evaluate to true, thus making SetUnhandledExceptionFilter() a moot point.

One simple solution (I think) would be

1. Write the status as STARTED to a status file when the application starts
2. Update it to CLOSED when application exits

You can check this status file to ensure whether the application closed normally or not.

One thing is that, when an application crashes no OnClose() like functions are called. Actually the OS is terminating the process.

You cannot do this for a single window.
Title bar size is a global setting which will effect all windows.

For your requirement you will have to do some skinning like custom drawing on the dialog and handle the WM_NCHITTEST message.

What I meant is all Windows on the system.
SystemParametersInfo is also used for system-wide settings.

ya i tried like this..

NONCLIENTMETRICS n;
n.cbSize = sizeof( NONCLIENTMETRICS );
::SystemParametersInfo( SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS) , &n , 0);
n.iCaptionHeight = 28;//where as default value is 25...
::SystemParametersInfo( SPI_SETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS) , &n , SPIF_SENDCHANGE);

it was increasing but when i revert iCaptionHeight to 25...im able to see the change titlebar but captions in the registry were looking weired...so pls let me know if there is any possibility to change the titlebar only in my application

You can have a wrapper class also with Visual Studio 2003.
(I've tested the following steps with Visual Studio 2005, but I suppose they are the same on your Visual Studio version).

Create a MFC application having care of enabling the ActiveX controls check of the Advanced features tab of the MFC Application Wizard window.
Select Project->Add Class item of Visual Studio Main menu.
Choose the MFC node on the treview in the newly appeared window.
Select MFC Class From ActiveX Control.
Click button Add.
Choose Microsoft Communication Control... in the newly appeared list.
Click button Add.

Did you try using CListCtrl::FindItem[^] to find and CListCtrl::SetItemState[^] to select the items?

I m trying this,but this work on one fixed Listctrl, and find item from first column only .

its not find string from entire list.

Basically i m working on SDI type splitter application,here i m split the view in one row and two column.

for first column i m using TreeView Derived Class,and for second Column i m using FormView Derived Class .

each formview has one ListCtrl where i want to perform find operation.

On Click event of Tree on different Tree Item replace the different Form View in Second column.

Ctrl+F use as shortcut for find.

so whenever i press Ctrl+F the find dialog must appear and find the text that is typed in find dialog in corresponding list where the Ctrl+F pressed.

Please help me for this.

if possible please explain me with any example.

Thanks in advance.

Well, you could try iterating thorough the items of the list control yourself, querying for the strings in the columns and comparing them, so something like this:

for (int row = 0, endRow = the_list.GetItemCount(); row < endRow; row++) //Iterate thorough the rows
{
  for (int col = 0; col < column_count; col++) //Iterate the "columns of this row"
  {
    CString Text;
    Text = the_list.GetItemText(row, col);
    if (Text.CompareNoCase(the_text_to_search_for) == 0)
    { //This "cell" contains the text we are searching for, let's select this row for example
      the_list.SetItemState(row, LVIS_SELECTED, LVIS_SELECTED);
      break; //break from the column iteration since we already found the string, no need to look for more
    }
  }
}

How about this?
